Invention Patent Descriptive Report for HIGH EFFICIENCY, HIGH OUTPUT TRANSMISSION.
CROSS REFERENCE TO RELATED APPLICATIONS [001] This application claims priority for US Serial Patent Application No. ^Q 62 / 438.201 (Registration Number EATN1100-P01), filed on December 22, 2016, entitled HIGH EFFICIENCY, HIGH OUTPUT TRANSMISSION, which is incorporated into this document by reference in its entirety.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION [002] Without limitation to a particular field of technology, the present disclosure is directed to transmissions configured for coupling to a primary engine and more particularly to transmissions for vehicle applications, including truck applications.
[003] Transmissions play a critical role in translating the energy supplied by a primary engine to a final load. The transmission serves to provide a change in speed ratio between the primary motor output (for example, a rotating axle) and a load-boosting input (for example, a rotating axle coupled to wheels, a pump or other axis-responsive device boost). The ability to provide selectable speed ratios allows the transmission to amplify torque, keep the primary engine and load speeds within the desired ranges for these devices and selectively disconnect the primary engine from the load under certain operating conditions. [004] Transmissions are subject to several conflicting restrictions and operational requirements. For example, the transmission must be able to provide the desired torque multiplication range while still handling the input torque requirements of the system. Furthermore, from the point of view of the global system, transmission represents

2/106 an overload device - the space occupied by the transmission, the weight and the interface requirements of the transmission are all general aspects for the system designer. Transmission systems are highly complex and take a long time to design, integrate and test; thus, transmission is also often necessary to meet the system integrator's expectations of past or historical transmissions. For example, a reduction in the space occupied by a transmission may be desirable in the long run, but for a given system design it may be more desirable for a space occupied to be identical to a previous generation transmission or as close as possible.
[005] The previously known transmission systems suffer from one or more drawbacks within a system as described below. To manage noise, robustness and structural integrity problems, previously known high-output transmission systems use steel for the transmission housing. In addition, previously known high-output transmissions use a large countershaft with high-strength gears to manage high loads through the transmission. The previously known gear sets have relatively few degrees of design freedom, which means that any deficiencies in the design need to be put in the adjacent transmission elements. For example, axial loads through the transmission, noise generated by gears and installation problems, such as complex gear timing problems, require a robust and potentially overly designed system in housing, bearing and / or installation procedures. High-output transmissions previously known, such as for trucks, typically include multiple interfaces to the surrounding system (for example, electrical, air, hydraulic and / or refrigerant), each requiring design and
Petition 870190057036, dated 06/19/2019, p. 25/213
3/106 integration and introducing a point of failure in the system. The previously known high-output transmissions include a cooler to protect transmission parts and fluids from overheating in response to the heat generated in the transmission. The previously known high-performance transmissions use concentric clutches that require complex performance and service. Therefore, there remains a need for improvements in the design of high production transmissions, particularly truck transmissions.

DETAILED DESCRIPTION [0077] Referring to Fig. 1, an example of transmission 100 is presented having one or more aspects of the present disclosure. The transmission example 100 includes a main housing 102, the main housing 102 defines the outer shape of portions of the transmission 100 and in certain embodiments the main housing 102 includes one or more components made of aluminum. The main housing example 102 is coupled to a clutch housing 104, wherein the clutch housing 104 includes or is operationally coupled to a clutch 106. The transmission example 100 further includes a rear housing 108. The rear housing 108 provides aspects of the transmission housing 100 at the rear, including in certain embodiments a set of planetary or helical gears arranged inside the rear housing 108, having structural coupling with a
Petition 870190057036, dated 06/19/2019, p. 36/213
14/106 output shaft assembly 110.
[0078] Example transmission 100 includes an integrated driver housing 112 coupled to main housing 102. The housing of integrated driver 112 in the example in Fig. 1 is coupled to the top of transmission 100, and main housing 102 includes an opening ( (not shown) in the position where the integrated driver housing 112 is coupled to the main housing 102. In the example of transmission 100, the opening in the main housing 102 provides access to the drivers operatively coupled to the integrated driver housing 112, including, for example, a driver clutch and / or one or more gear shift actuators. The example transmission 100 also includes a transmission control module 114 (TCM), where the example TCM 114 directly connects to the integrated driver housing 112.
[0079] The arrangement of transmission aspects 100 shown in Fig. 1 is an example and a non-limiting arrangement. Other provisions of various aspects are contemplated in this document, although in certain embodiments, more of the provisions depicted in Fig. 1 may be advantageous as described throughout the present disclosure. Particular provisions and aspects of the transmission 100 can be included in certain modalities, including one or more of the aspects arranged as depicted and one or more aspects arranged in a different way as will be understood by a person skilled in the art contemplating an application and / or installation in particular.
[0080] The description of the spatial arrangements in the present disclosure, for example, front, rear, top, bottom, above, below and the like, are provided for convenience of description and for clarity in the description of the component list. The description of a particular spatial arrangement and / or relationship is not limited to modalities
Petition 870190057036, dated 06/19/2019, p. 37/213
15/106 of a transmission 100 consistent with the present description, in a particular transmission 100 can be arranged in any manner understood in the art. For example, and without limitation, a particular transmission 100 can be installed so that a rear position can face a front, side or other direction, as installed in a vehicle and / or application. In addition or alternatively, transmission 100 may be rotated and or tilted about any axis, for example, and without limitation, at an azimuth angle to a transmission system (for example, clutch rotation angle 106) and / or a tilt from front to back, for example, to accommodate an angular transmission. Consequently, one or more components may be arranged relatively as described in this document and a component described as above another component may, however, be the vertically inferior component as installed in a particular vehicle or application. In addition, the components for certain embodiments may be arranged in a relative manner different from that described here, resulting in a component described as above, another component being vertically inferior for certain embodiments or resulting in a component described as the rear of another being positioned at the rear. in front of another, depending on the observer's reference structure. For example, a transmission example 100 includes two countershafts (not shown) and a first feature in particular engaging an upper countershaft can be described and depicted as above a second particular resource engaging a countershaft; however, it is contemplated in this document that a provision with the first resource in particular engaging the lower countershaft in the second resource in particular engaging the upper countershaft is consistent with at least certain modalities of the present disclosure, except where the context indicates the
Petition 870190057036, dated 06/19/2019, p. 38/213
16/106 otherwise.
[0081] Referring to Fig. 2, a transmission 100 is shown in a top view, where transmission 100 shown in Fig. 2 is consistent with transmission 100 shown in Fig. 1. In the top view of transmission 100, the rear housing 108, the clutch housing 104 and the main housing 102 remain visible. In addition, the integrated drive housing 112 and TCM 114 are visible on top of main housing 102. Example transmission 100 further includes a clutch drive housing 202 that provides accommodation for a clutch drive assembly (not shown in Fig. 2). The clutch actuator housing 202 is represented as a part of the integrated drive housing 112 and positioned on top of the transmission 100. The example of clutch actuator housing 202 and clutch actuator assembly, as evidenced by the position of the actuator housing clutch 202, engages an upper countershaft on the rear side; however, a lubrication pump assembly can engage one or more countershafts in any axial position along the transmission 100. More details of an example lubrication pump assembly are described elsewhere in the present disclosure.
[0082] The example transmission 100 of Fig. 2 further illustrates the output shaft assembly 110 at a rear end of the transmission, in the example shown as a transmission output shaft assembly 110; however, any design of the output shaft assembly 110 for the particular application is contemplated in this document. The transmission 100 further illustrates an input shaft 204, in the example, the input shaft 204 extends through the clutch 106 on the outside of the transmission 100, engages with a main motor shaft, such as the tail shaft. An example of input shaft 204 includes a splined hitch with a main motor shaft, although
Petition 870190057036, dated 06/19/2019, p. 39/213
17/106 any coupling arrangement comprised in the art is contemplated here.
[0083] The transmission example 100 shown in Fig. 2 includes a single air inlet line (not shown), which in the example is pneumatically coupled to the integrated drive housing 112. In certain embodiments, transmission 100 includes a drive clutch and one or more shift actuators, where the clutch actuator and shift actuator (s) are powered by a single or common air inlet supply line, as shown in the example in Fig. 2. Additionally or alternatively, each of the actuators can be powered by separate power inputs and / or alternative energy sources, such as, but not limited to, a hydraulic and / or electrical source.
[0084] Referring to Fig. 3, a transmission 100 arranged in an orientation similar to the representation shown in Fig. 1 is illustrated to more clearly show certain aspects of transmission 100. Example transmission 100 includes integrated driver housing 112, in that an air inlet port 302 provides pneumatic access to the supply of air inlet for engaging the clutch actuator and the shift actuator (s). Transmission example 100 includes only a single power inlet to operate all actuators and in other embodiments the single power inlet is included as an air inlet port 302. In the embodiments, a single air supply is provided for the drive pneumatic clutch actuator (such as a linear clutch actuator (LCA) and each of the gearshift actuators (for example, actuators for front, main and rear gearboxes). In the modalities, the air supply is handled in of the integrated driver housing via a set of conduits that accept air from the air inlet supply
Petition 870190057036, dated 06/19/2019, p. 40/213
18/106 and provide air to feed the movement of each of the actuators. The conduits can be integrated (for example, machined, cast, etc.) in the integrated driver housing / frame, so that air is supplied without the need for separate hoses or the like, between the air inlet supply and the respective actuators for clutch and gear movement. Among other benefits, this eliminates potential points of failure (such as leaking hoses or poor hose connections) and allows very precise control (because, among other reasons, the air volume is smaller and more precisely defined for a hose-based system ). It is to be understood that a particular integrated driver housing 112 includes the number and type of power access points for the particular arrangement, such as an electrical and / or hydraulic input and / or more than one input of a given type, such as like pneumatics. Additionally or alternatively, in certain embodiments, the transmission 100 includes one or more energy inlets positioned at locations other than the location of the air inlet port 302 in the example of Fig. 4.
[0085] The example transmission 100 shown in Fig. 3 also shows a sensor port 304. In the example in Fig. 3, port 304 of the sensor couples a controller in TCM 114 to a speed sensor in the output shaft assembly 110 of transmission 100. Referring to Fig. 4, a sensor coupler 404 operationally couples a sensor (for example, a speed sensor of any type, such as a Hall effect, variable reluctance, tachograph or similar) to the sensor connector 304, for example, to provide an output shaft speed value for TCM 114. Additionally, transmission 100 includes an oil pressure sensor 406. In the embodiments, a transmission data 100 can include any number of sensors of any type desired, including having no
Petition 870190057036, dated 06/19/2019, p. 41/213
19/106 speed and / or other sensors. In certain modalities, the type and source of information may vary with the control and diagnostic characteristics present in the system. In addition, or alternatively, any detected value can instead be determined from other known values in the system (for example, a virtual sensor, model or other construction or derivation of a given value from other sensors or other known information ) and / or the detected value can be determined from a data link communication or alternative source, instead of or in addition to a direct sensor coupled to a controller. The controller can be in communication with any sensor and / or driver anywhere on the transmission 100 and / or within a system including or integrated with the transmission 100, such as a transmission, vehicle or other application, as well as with remote systems, such as through one or more communication networks, such as Bluetooth ™, cellular, WiFi or similar, including for remote systems used in the cloud, such as telematics and similar applications, among others.
[0086] Transmission example 100 includes a pair of electrical connectors 402 (reference to Fig. 4), represented as two 20-pin connectors, in the example shown in Fig. 4, although any electrical interface can be used. An example TCM 114 includes an electrical connection between TCM 114 and the integrated drive housing 112, for example, where TCM 114 connects to the integrated drive housing 112 providing electrical datalink communication (for example, between a controller present in the integrated drive and the controller in TCM 114 - not shown) and / or direct control of the actuator actuator in the integrated actuator housing 112. In certain modalities, a single controller can be present that performs all operations on the transmission 100 and / or the functions of transmission 100 can be divided between one or more controllers other than the

20/106 position of the controller shown in Fig. 4. For example and without limitation, a vehicle controller, application controller, engine controller or other controller present in transmission 100 or global system may include one or more functions of transmission 100. [0087] Example transmission 100 further includes a clutch 106. Example clutch 106 includes a clutch face 306 and one or more torsion springs 308. The example of clutch face 306 includes a number of friction plates 310 and the clutch face 306 presses against an opposite face from a main engine (not shown), for example, a flywheel. The torsion springs 308 of the example clutch face 306 provide rotary damping of the clutch 106 to the transient forces, maintaining the steady state alignment of the clutch 106. The clutch face 306 can alternatively be any type of clutch face, understood in the art, including, for example, a single friction surface instead of friction plates 310. In the example of the clutch face 306, the friction plates 310 are included as a portion of the clutch face 306. The divisions between the clutch plates are provided as grooved divisions of the clutch face base material 306 to provide the desired performance (for example, frictional performance, debris management and / or heat transfer functions), but any configuration of the clutch face 306 including alternate groove patterns and / or no groove presence is contemplated here. The material of the example clutch face 306 can be any material comprised in the art, including at least one ceramic material and / or organic clutch material. In the modalities, as illustrated in more detail below, clutch 106 can be positioned off-axis relative to the main engine, it is arranged around (such as through a configuration

21/106 horseshoe or similar) the main motor (eg an axle) is pivotally anchored on one side (such as by a hinge or similar mechanism that allows it to turn in the desired direction of clutch movement 106 and is actuated by the linear clutch actuator (which can also be positioned off-axis, opposite the anchoring side), so that the linear actuation causes the clutch to rotate in the desired direction).
[0088] Referring to Fig. 4, an example of transmission 100 is shown from a side view, with the output shaft assembly 110 positioned on the left side of Fig. 4, in the clutch housing 104 positioned on the right side of the Fig. 4. Transmission 100 illustrated in Fig. 4 includes numerous features that may be present in certain modalities. For example, numerous 408 fins and / or projections are present that provide selected voltage characteristics, housing stress management and / or selected heat transfer characteristics. The transmission example 100 also depicts a PTO 410 interface that allows access to a PTO installation to engage the transmission on a lower side. In addition or alternatively, transmission 100 may include a second PTO interface at the rear of the transmission (not shown), for example, to allow PTO engagement at the rear of transmission 100. A rear PTO engagement may be provided with a hole (which can be connected to a non-PTO installation) or other access installation, where PTO can be engaged, for example, with a pipe shaft engaging one of the transmission countershafts 100 at a first end and providing an engaging surface, such as as a groove, at a second end extending from the transmission 100. The transmission example in Fig. 4 additionally represents a number of lifting points 412, which are optionally present, and which can be arranged as

22/106 shown or in any other provision or position.
[0089] Referring to Fig. 5, another view of an example transmission 100 is provided representing a clear view of the clutch drive housing 202, the integrated drive housing 112, in TCM 114. The transmission example 100 also includes a a number of couplings 502 between the main housing 102 and a rear housing 108 and a number of couplings 504 between the main housing 102 and the housing 104 of the clutch. In certain embodiments, the selection of frame elements (102, 104, 108) that includes the transmission portions of the transmission 100 may be distinct from the selection of frame elements (102, 104, 108), as shown in Fig. 5. For example, certain carcass elements can be combined, divided and / or provided at separation points other than those shown in Fig. 5. Several considerations that can be included in determining the selection of carcass elements include the strength of materials used in manufacturing , the transfer of energy from transmission 100, the transfer of torque (maximum and / or transient) from transmission 100, manufacturing considerations (including positioning at least the housing and devices within the housing during manufacture, materials selected for the housing and / or manufacturing costs and repeatability considerations) and cost and / or reliability concerns associated with each the housing interface (e.g., interface 506 between main housing 102 and rear housing 108).
[0090] Referring to Fig. 6, another view of an example transmission 100 is provided representing a clear view of the PTO 410 interface. The example of PTO 410 interface is an 8-screw interface provided on the underside of the transmission 100. Referencing Fig. 7 shows a schematic view of a transmission housing 700. Housing 700 includes a latch opening

23/106 of driver 702 positioned on top of the transmission. The driver slot 702 is sized to accommodate the attachment of the integrated driver housing 112 and to allow the drive elements to be positioned on the transmission 100. The position, size, shape and other elements of a driver hitch opening 702 , when present, can be selected according to the particular resources of the triggers for the system. The transmission example 100, driver hitch opening 702 and integrated driver housing 112, are easily accessible with access to the top of the transmission 100, and can be installed, serviced, maintained or otherwise accessed or manipulated without removal of the transmission 100 of the application or vehicle and / or without disassembling the transmission 100. Example housing 700 also includes a clutch actuator engagement opening 704, sized to accommodate the clutch housing portion of the integrated actuator housing 112 and to allow the clutch actuator to be positioned on transmission 100. In example housing 700, displacement actuators (not shown) are positioned on transmission 100 through the coupling opening on actuator 702, and a clutch actuator is positioned on transmission 100 through the coupling opening of clutch actuator 704, and it can be seen that a single step installation of the integrated drive housing 112 provides isolation of all primary drives for transmission 100, as well as providing a single convenient location for access to all primary drives.
[0091] Referring to Fig. 8, an example of transmission 100 is shown schematically in a sectional view. The section plane in the example of Fig. 8 is a vertical plane through transmission 100. The example of transmission 100 is capable of providing transfer

24/106 power transfer from a clutch interface primary motor 106 to the input shaft 204, from the input shaft 204 of a first portion of the main shaft 804, to a second portion of the main shaft 806 operatively coupled to the first main shaft portion 804 and from the second main shaft portion 806 to the output shaft assembly 110. The transmission example 100 is operable to adjust torque multiplication ratios along the transmission, to engage and disengage the clutch 106 from the primary motor (not shown) and / or position transmission 100 in a neutral position where, even if clutch 106 is engaged on the main motor, torque will not be transmitted from clutch 106 to output shaft assembly 110.
[0092] With additional reference to Fig. 8, a clutch hitch fork 808 is shown in a first position 808A consistent with, in certain embodiments, clutch 106 being engaged with the main motor (ie clutch 106 in a forward position). For the sake of clarity of the description, clutch coupling fork 808 is simultaneously represented in a second position 808B consistent with, in certain embodiments, clutch 106 being disengaged with the main motor (i.e. clutch 106 in a stowed position) . The example clutch coupling fork 808 is operationally coupled at a first end to a clutch actuator, which in the example in Fig. 8 engages the clutch coupling fork at the top end of the 808 clutch coupling fork. example clutch coupling 808 is attached to a second end, providing a pivot point for the clutch coupling fork 808 to move between the first position 808A and the second position 808B. A clutch hitch fork 808 of the example in Fig. 8 allows for convenient

25/106 t of the clutch 106 with a linear actuator, however, in certain embodiments of the present description, any type of clutch actuation can be used, including a concentric clutch actuator (not shown) and / or other type of clutch device linear clutch actuation.
[0093] The example transmission 100 further includes an input shaft gear 810 selectively coupled to the input shaft 204. The inclusion of the input shaft gear 810, when present, allows for additional distinct gear ratios provided by the input shaft 204 , for example, a gear ratio where the torque is transmitted to the input shaft gear 810, where the torque is transmitted directly to the first portion of shaft 804 (for example, with the input shaft 204 and the first portion of main shaft 804 coupled to a first feed gear 812). In certain embodiments, the first forward gear 812 shared between the input shaft 204 and the first main shaft portion 804 may be called a dividing gear, although any specific naming convention for the first forward gear 812 is not limiting to the present description.
[0094] Example transmission 100 further includes a number of gears selectively coupled to the first main shaft portion 804. In the example in Fig. 8, the first forward gear 812, a second forward gear 814 and the third forward gear 816 are shown, and a first reversing gear 818 is still shown. In the example, the first feed gear 812 is attachable to any of the input shafts 204 and / or the first main shaft portion 804. When the input shaft 204 is coupled to the first feed gear 812 and the first shaft portion main 804 is not, it is gearing reason
Petition 870190057036, dated 06/19/2019, p. 48/213
10/26 between the input shaft 204 and the first main shaft portion 804. When the input shaft 204 is coupled to the first feed gear 812 and the first main shaft portion 804 is also coupled to the first feed gear 812 , the input shaft 204 and the first main axis portion 804 rotate at the same angular speed. The number and selection of gears depends on the desired number of transmission ratios of the transmission and the number of gears represented is not limiting to the present disclosure.
[0095] The transmission example 100 further includes a planetary gear set 820, which couples the second main shaft portion 806 to the output shaft assembly 110 through at least two transmission ratios selectable between the second portion of main shaft 806 and the output shaft assembly 110. The transmission example 100 further includes at least one countershaft, the countershaft having an alignment gear with each of the gears attachable to the input shaft 204 in the first portion of main axis 804. The countershaft (s) transmit (s) selectively transmit energy between the input axis 204 in the first portion of the main axis 804, depending on which gears are rotatably attached to the input axis 204 and / or the first main axis portion 804. More details of the countershaft (s) are described below, for example, in the disclosure portion referenced in Fig. 9.
[0096] It can be seen that transmission 100 in the example in Fig. 8 provides up to 12 direct transmission ratios (2 x 3 x 2) and up to four reverse transmission ratios (2 x 1 x 2). A particular mode may include gear arrangements other than those depicted and / or may not use all available gear ratios. In modalities, an eighteen-speed automatic truck transmission can be provided, as well as providing three gears

27/106 in advance, three main gears and two planetary gears, here referred to as a three by three by two architecture. Likewise, a twelve-speed automatic truck transmission can be provided providing three forward gears, two main gears and two planetary gears, or other combinations.
[0097] Referring to Fig. 9, an example of transmission 100 is shown schematically in a sectional view. The example in Fig. 9 represents a section through a plane that intersects with the double countershafts 902, 904. The example countershafts 902, 904 are positioned 180 ° on either side of the first main shaft portion 804 In certain embodiments, transmission 100 may include only a single countershaft and / or more than two countershafts. The position and angle of countershafts 902, 904 shown in Fig. 9 is a non-limiting example and countershafts 902, 904 can be adjusted as desired for the application. Each of the example countershafts 902, 904 includes a gear layer 906 which engages with a corresponding gear on the input shaft 204 and / or the first main shaft portion 804, respectively. Example transmission 100 includes gears 906 rotatably attached to countershafts 902, 904, with the corresponding gears on the input shaft 204 and / or the first main shaft portion 804 being selectively fixed to the input shaft 204 and / or the first main shaft portion 804. Additionally or alternatively, the gears 906 may be selectively rotatably attached to the countershafts 902, 904, with one or more of the corresponding gears on the input shaft 204 and / or the first main shaft part 804 rotatingly attached to the input shaft 204 and / or the first main shaft part 804. The descriptions of change drivers presented in this document use the convention that
Petition 870190057036, dated 06/19/2019, p. 50/213
28/106 gears 906 are rotatably attached to countershafts 902, 904 and changes in which the gears are rotatably fixed or selectively rotatably fixed would lead to corresponding changes in the drive.
[0098] Example transmission 100 includes a first driver 908, for example, a shift fork, which moves (for example, side by side and / or up or down) under drive, to selectively rotate the shaft input 204 to one of the countershafts 902, 904 or to the first main shaft portion 804. The first actuator 908 interacts with a gear coupler 910, and in certain embodiments, the gear coupler 910 includes a timing component as understood in the art . The first driver 908 can also be used to position the gear coupler 910 to an intermediate position where the input shaft 204 is rotationally dissociated from both countershafts 902, 904 and the first portion of the main shaft 804, for example. example, putting transmission 100 into a neutral operating state. In certain embodiments, the first driver 908 is a portion of, and is controlled by, an integrated driver assembly 1300 (e.g., reference Fig. 13) positioned within the integrated driver housing 112.
[0099] The transmission example 100 also includes a second driver 912 which, under actuation, such as movement from side to side and / or up or down, selectively couples rotationally one among the first direct gear 812 and the second direct gear 814 to the first main shaft portion 804, rotatingly coupling the countershafts 902, 904 to the first main shaft portion 804. The transmission example 100 also includes a third drive 914 which, under drive, selectively couples one of the third gear rotationally direct 816 and the gear
Petition 870190057036, dated 06/19/2019, p. 51/213
29/106 inverse gem 818 to the first main shaft portion 804, thereby rotatingly coupling countershafts 902, 904 to the first main shaft portion 804. In certain embodiments, the second driver 912 and the third driver 914 are operable to be positioned in an intermediate position where the first main shaft portion 804 is rotationally decoupled from both countershafts 902, 904 - for example, placing the transmission 100 in a neutral operating state. In certain embodiments, at least one of the second actuator 912 and the third actuator 914 are positioned in the intermediate position at any given time, preventing the coupling of countershafts 902, 904 to the first main shaft portion 804 at two different speed ratios simultaneously. In certain embodiments, the second driver 912 and the third driver 914 are portions or are integrated with, and are controlled by, the integrated driver assembly 1300 positioned within the housing of the integrated driver 112.
[00100] In example transmission 100, the second driver 912 interacts with a second gear coupler 916, and the third driver 914 interacts with a third gear coupler 918, wherein each of the second and third gear couplers 916, 918 can include a synchronization component. According to the arrangement shown in Fig. 9, the first, second and third actuators 908, 912, 914 are operable to provide a number of different direct gear options, reflecting different combinations of gear ratios (for example, six, twelve or eighteen transmissions) and a number (for example, two) of different reverse gear ratios. The planetary gear set 820 may include a clutch (such as a 920 sliding clutch) configured to position the planetary gear set 820 and provide two different ratios between the second
Petition 870190057036, dated 06/19/2019, p. 52/213
30/106 main shaft portion 806 and the output shaft assembly 110. Accordingly, according to the arrangement shown in Fig. 9, transmission 100 is operable to provide twelve different forward gear ratios and four reverse gear ratios different. In certain embodiments, one or more of the available gear ratios may not be used, and a selection of the number of forward gears, number of reverse gears and number of drives may be different from the arrangement shown in Fig. 9.
[00101] The transmission example 100 provides a direct transmission arrangement, for example, when the first drive 908 couples the input shaft 204 to the first main shaft portion 804 (gear coupler 910 on the right in the orientation shown in Fig. 9 ) and where the second driver 912 couples the first main shaft portion 804 of the first forward gear. The direct drive operation transfers energy through the planetary gear set 820, with the sliding clutch 920 providing either gear reduction (for example, sliding clutch 920 positioned to the right in the orientation shown in Fig. 9) or full direct transmission of the transmission 100 (for example, sliding clutch 920 positioned to the left in the orientation shown in Fig. 9). In certain embodiments, the direct drive may be a higher gear ratio than transmission 100, and / or the drive may include one or more overdrive gears. Determining the number of gears, how many gears are forward and / or reverse and the reasons for each gear, including whether and how many overdrive gears may be present and how many combinations of gear ratios are selectable, are configurable features that depend on the characteristics response times for a particular application. An example of transmission 100 includes the operational coupled integrated driver assembly 1300
Petition 870190057036, dated 06/19/2019, p. 53/213
31/106 to the 920 slip clutch, for example, with a shift fork (not shown) mounted on a shift rail.
[00102] The transmission example 100 represents the PTO 410 interface positioned in the vicinity of the lower countershaft 904. In certain embodiments, the transmission 100 includes a main housing 102, where the main housing 102 is made of aluminum and / or is a fused component. It will be understood that material restrictions and component stress management indicate that certain characteristics of an aluminum housing will be larger, thicker or otherwise modified in relation to a steel housing. For example, the protrusions of the screws of the PTO 410 interface can be deeper and project further into the main housing 102 for a PTO 410 interface designed in an aluminum housing compared to a similar installation designed in a steel housing. Cast components, in certain modalities and depending on the casting process used, impose certain restrictions on the design of the component. For example, for certain casting processes, it may be beneficial to limit a component to having a monotonically increasing external carcass shape or profile. The transmission example 100 includes ratio selections and gear sizing, as well as position selection of the PTO 410 interface, so that a lower countershaft gear 904 having a greater radial extension of a gear train centerline is positioned in the vicinity of the PTO 410 interface. An example of transmission 100 includes the PTO device that accesses transmission 100 on the PTO 410 interface to be fed by the first forward gear 812 (for example, the dividing gear) through the corresponding countershaft gear.
[00103] In certain embodiments, transmission 100 allows the coupling of a PTO device (not shown) directly with a coupling

32/106 gear engaging the lower countershaft 904, without having to use an intermediate gear or similar mechanical configuration to extend the power transfer of the lower countershaft 904. It can also be noted that the transmission example 100 includes a geometric profile of the gears in the gear train, such that an easily castable main housing 102 can be positioned on the gears after the gear train is assembled and / or the gear train is mounted on the main housing 102 in a simple manner. In addition, it can be noted that transmission example 100 includes provisioning for screw spares from the PTO 410 interface, even when deeper screw spares are provided, such as an application having an aluminum main housing 102.
[00104] The transmission example 100 also includes a braking device 922, selectively coupled to at least one of the countershafts 902, 904. In the example shown in Fig. 9, the braking device 922 is selectively coupled to the counter - lower axle 904, however, a braking device 922 may be attachable to one of the countershafts 902, 904 and / or more than one braking device may be present in coupling to each countershaft present. The braking device 922 provides the ability to decelerate the countershaft and / or the transmission line, to stop the countershaft and / or the transmission line, and / or to provide stationary holding capacity to the transmission line. An example of a braking device 922 includes a braking device driver 924 (a pneumatic inlet in the example in Fig. 9) that can be controlled pneumatically by an integrated driver assembly 1300 positioned in the housing of the integrated driver 112. Additionally or alternatively, any other means of actuation and controller is contemplated in this document, including at least one actuator
Petition 870190057036, dated 06/19/2019, p. 55/213
33/106 electric and / or hydraulically operated, and / or any other transmission line braking device, is additionally contemplated in this document. Additionally or alternatively, any other type of braking device may be included within the transmission 100 and / or positioned upstream or downstream of the transmission 100, for example, a hydraulic retarder and / or an electrical braking device (not shown), which can be controllable by a driver in the integrated driver assembly 1300 positioned in the integrated driver housing 112, by TCM 114 and / or by another control device in the system (not shown).
[00105] The transmission example 100 includes the output shaft assembly 110. The example of output shaft assembly 110 includes an output shaft 926, in which the output shaft is rotatably coupled to the planetary gear set 820. The output shaft assembly 110 further includes a transmission line adapter 928 coupled to output shaft 926, and configured to engage a downstream device (not shown) on the transmission line. The transmission line adapter 928 can be any type of device known in the art, and the specific representation of the transmission line adapter 928 is non-limiting. The selection of a 928 transmission line adapter will depend in part on the application, the type of downstream device and other considerations known in the art.
[00106] Referring to Fig. 10, an example of transmission 100 is shown schematically in a sectional view. The cutting plane and the example of Fig. 10 is a plane that intersects a clutch actuator 1002 on the transmission line (for example, including the input shaft four, the first and second main shaft portions 804, 806, in the set output shaft 110). The representation in Fig. 10 illustrates the clutch engagement unit 808 in the first position 808A and in the second position 808B. The transmission example

100 includes a linear clutch actuator 1002, positioned inside the housing of the clutch actuator 202 and extending to the clutch hitch unit 808. In the example in Fig. 10, the pneumatically operated clutch actuator 1002 applies a force of pressure to the clutch hitch unit 808 and return to a stowed position in response to the force of the clutch hitch unit 808. The clutch actuator example 1002 provides a normally engaged clutch 106, such that if the clutch actuator 1002 is not actively engaging the clutch engagement unit 808, clutch 106 extends and engages. The example of clutch actuator 1002 is a pneumatic linear clutch actuator (LCA) that pushes to engage, however, any type of clutch actuator is contemplated in this document, for example and without limitation, a pull-to-type actuator. engage (for example, using a catapult or other mechanical arrangement), hydraulic and / or electric actuation, and / or engaging with a clutch normally engaged or normally disengaged 106. In certain embodiments, the clutch actuator 1002 includes a volume of dead air close to zero in the stowed position. Examples of support features for keeping dead air volume close to zero for clutch actuator 1002 are described below. In certain embodiments, the use of a linear actuator, the inclusion of a dead air volume close to zero and the positioning of the clutch actuator housing 202 as part of the integrated actuator housing 112 support several improvements of one or more among accessibility to clutch actuator housing 202, accessibility to clutch actuator 1002, improvements in control and / or repeatability of the clutch actuation, reduction of points of failure and / or diagnosis or determination of the precise position of the clutch face 306 (including depending on the clutch

35/106 act 106 wear out over time). In certain embodiments, a dead air volume close to zero includes a volume 1004 behind the clutch actuator 1002 on one supply side, where the volume 1004 is small enough that the delivered air immediately begins to put in a driving force in the clutch actuator 1002 and / or in such a way that a consistent initial air volume starts, each time, a consistent movement in the clutch actuator 1002. Examples of air volumes close to zero include, without limitation, the clutch actuator 1002 positioned against an air supply pipe (for example, as shown in Fig. 10), a volume small enough that the clutch actuation starts after applying the supply pressure within a selected response time (for example, 5 ms, 10 ms, 20 ms, 40 ms, 100 ms and / or 200 ms) and / or a volume less than a specified volume difference behind the clutch actuator 1002 on the supply side between the e actuator mbreaction 1002 in a current rest position and clutch actuator 1002 in a predetermined rest position (for example, fully positioned against a stop), where the specified volume is approximately zero, less than 0.1 cc, less than 0.5 cc and / or less than 1 cc. The examples provided for a volume close to zero are illustrative and not limiting. An individual skilled in the art, who has the benefit of the present disclosure and information normally available, when contemplating a particular modality, can readily determine a volume close to zero for a contemplated application. Some considerations for determining a dead air volume close to zero include, without limitation, the pressure and / or rate of drive air supplied, the desired response time for clutch actuator 1002, the computation of resources available on TCM 114 or elsewhere in the system, and / or the physical response of the

In certain embodiments, the transmission 100 is sized similarly to transmissions previously known and available for similar applications and, in certain embodiments, the transmission is smaller or larger than the transmissions previously known and available for similar applications. In certain embodiments, the transmission 100 includes frame elements 102, 104, 108 that provide additional space beyond what is necessary to accommodate the internal aspects of the transmission (gears, shafts, drivers, lubrication system, etc.), for example, to match with transmission 100 to an expected integration size and / or to use one or more housing elements 102, 104, 108 in various configurations of transmission 100 (for example, to include additional gear layers on input shaft 204 and / or in the first main shaft portion 804). The modular construction of the housing elements 102, 104, 108, gears, shafts, lubrication pump assembly 1300 and other aspects of the transmission 100 similarly promote the reuse of certain aspects of the transmission 100 through various configurations, while other aspects ( for example, clutch housing 104, main housing 102 and / or rear housing 108) are readily adapted to the specific needs of a given application or configuration. The exemplary transmission 100 additionally provides immediate access to components, such as the drives and / or clutch bearings that, in previously known and available transmissions, require more complex access to install, repair, integrate and / or maintain those components.

58/106 lou alternatively, transmission 100 is a high efficiency transmission.
[00138] The term high output, as used in this document, should be understood broadly. Non-limiting examples of a high output transmission include a transmission capable of operating at more than 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900 , 2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900 and / or more than 3000 foot-pounds of input torque at a specified location (for example, on the clutch face, input shaft or another location in the stream).

59/106, any characteristics described can be included or excluded from certain modalities and be included within the present disclosure. In addition, the described examples of a high production transmission are not limiting, and in certain embodiments, a transmission may be a high output transmission for the purposes of an application, vehicle, power and / or torque, but not for the purposes of others applications, vehicles, power ratings and / or torque ratings.
[00139] The term high efficiency, as used in this document, should be understood widely. A high efficiency transmission is a transmission that has a relatively high output value and / or a high level of benefit, in response to a given input value and / or cost level. In certain modalities, the high output value (and / or benefit level) is higher than that normally present in previously known transmissions, the given input level (and / or cost level) is lower than that commonly present in previously known transmissions and / or a difference or ratio between the high yield value (and / or benefit level) and the input level (and / or cost level) provided is greater than that normally present in previously known transmissions. In certain embodiments, the output value and / or the input level are within the ranges observed in previously known transmissions, but the transmission is nevertheless a highly efficient transmission - for example, because the difference or relationship between the value high output and the input level given is high and / or because other benefits of certain modalities of the present disclosure are additionally evident in the exemplary transmission. A high production value should be understood as covering a relatively high level of benefit, for example, a lower weight transmission has a higher output value, where weight is considered to be the output side of the efficiency. A low entry value

60/106 da should be understood as covering a relatively low cost or an input quantity, for example, a lower weight transmission has a lower cost value, where weight is considered to be the input side of efficiency. Exemplary and non-limiting output values include a level of transmission torque (input, output or overall gear ratio), a number of available gear ratios, an amount of noise reduction, a description of power loss, reliability, durability and / or robustness value, ease of maintenance, quality of service, ease of integration and / or ease of installation, a responsiveness value (for example, clutch engagement and / or displacement), a consistency value (for example , repeatability of operations, consistent driver feel, high degree of matching a previously known setting), transmission-induced downtime values and / or a lifetime value. Exemplary and non-limiting input values include a transmission cost, transmission weight, transmission noise level, engineering design time, ease of manufacture and / or cost, installation and / or integration time (eg, time installation and / or engineering work to prepare the installation plan and / or configure other parts of a vehicle or application to accommodate the transmission), a total cost of ownership value, scheduled maintenance values, average maintenance and / or values repair time (eg time and / or cost) time values and / or application restrictions (eg torque or power limits - absolute, average time and / or in certain gear configurations). The descriptive examples of a high efficiency transmission are non-limiting, and any high efficiency descriptions known to a person skilled in the art, having the benefit of the disclosures in this document, are contemplated within the present disclosure. One versed in

61/106 technical, having the benefit of the disclosures in this document and information commonly known about a contemplated application or installation, such as the functions and priorities related to performance, cost, manufacturing, integration and total cost of ownership for the application or installation, can easily set up a high efficiency transmission.
[00140] It can be additionally seen that the exemplary transmission 100 provides, in certain modalities, a reduction in the general bearing and gear loads along the transmission 100, for example, through the use of high speed countershafts, helical gear for improve and / or optimize sliding and loading speeds of gears and / or molding of gear teeth to configure the contact area of gear teeth, structural integrity and control of sliding speed profiles and deflection of gear teeth. In certain embodiments, the use of high-speed countershafts allows for smaller and / or lighter components, including at least rotating components (for example, shafts and gears), bearings and lubrication systems. In certain embodiments, the use of helical gears and / or molded gear teeth allows the reduction of slip losses (for example, increased energy transfer efficiency and reduced heat generated) while also allowing a transmission 100 to meet restrictions of noise. In certain embodiments, the configuration to allow noise control allows certain aspects of the transmission 100 to be configured for other desirable purposes that would otherwise increase the noise emissions of the transmission 100, such as the use of aluminum boxes, configuring for use shift access and / or clutch actuators, the use of a linear clutch actuator and / or positioning access to larger transmission resources,

62/106 such as actuators, on top of the transmission that can place them in close proximity to a passenger compartment or other noise sensitive area in an application or vehicle. In certain embodiments, the use of helical gears allows a degree of freedom in thrust loads (axial), directing axial loads to selected positions in the transmission 100, such as a support bearing and / or a bearing positioned between axles having low differentials. speed and / or away from boxes or bearings.
[00141] In certain modalities, the use of additional high-speed countershafts or alternatively reduces the speed differences between axles, at least in selected operating conditions, and supports the management of axial loads in the transmission 100. In certain modalities, helical gears in a set of planetary gears provide a reduced length of countershafts (for example, countershafts do not need to extend to the output shaft), a reduction in a number of countershafts (for example, countershafts additional power transfer between a main shaft and the output shaft are not required). Additionally or alternatively, the helical gears in a planetary gear set are load balanced, in certain modalities, to remove the gear load from the housings and / or housings coupled to housings. In certain embodiments, the features of the transmission 100, including but not limited to axial load management features, provide load management through the use of efficient bearings, for example, with a reduced number or elimination of tapered bearings in the transmission 100. In In certain embodiments, the characteristics of the transmission 100 include a high efficiency lubrication system, for example, use of a smaller lubrication pump (for example, short lubrication cycles within the transmission 100, reduction or elimination of the e-slip rings)

In certain embodiments, transmission 100 provides lower energy transfer losses than previously known transmissions and / or provides similar or enhanced energy losses in a relative overload transmission to previously known transmission systems using a direct transmission, allowing other aspects of a system or application operates at speeds lower upstream of the transmission (for example, a load component such as a transmission line, rear center axle, wheels and / or pump axle) as desired to meet the operational objectives of these aspects.
[00142] In certain embodiments, the transmission 100 uses a clutch and displaces the gears using actuators that move elements or speed change drivers (for example, using displacement forks and sliding clutches, with synchronizing elements). An example and non-limiting application for transmission modalities is an automated transmission and / or an automated manual transmission. Certain aspects and characteristics of the present disclosure apply to automatic transmissions, manual transmissions or other transmission configurations. Certain resources, resource groups and resource subgroups may be applicable to any type of transmission and / or may have a specific value for certain types of transmission, as will be understood by one skilled in the art having the benefit of the present disclosure.
[00143] Referring to Fig. 41, an example of a 3800 clutch operation set is illustrated that illustrates certain aspects
Petition 870190057036, dated 06/19/2019, p. 86/213
64/106 of a clutch assembly and operational portions of the transmission 100 that interact with the clutch assembly. The exemplary clutch operating set 3800 provides a clutch 106 that responds to a linear clutch actuator 1002 and adjusts a clutch position 106 so that, as the clutch face uses 306, the engagement point of the linear clutch actuator 1002 remains constant for a selectable amount of wear on the 306 clutch face. The inclusion of a 3800 clutch operation set that responds to a linear clutch actuator 1002 and / or that provides a constant engagement point for a linear clutch actuator or concentric are optional configurations that are included in certain modalities of the transmission 100 and may not be included in other modalities of the transmission 100. Any 3800 clutch operating set known in the art is contemplated in this document, including alternative arrangements for providing engagement with a driver linear clutch valve 1002 and / or alternative arrangements to provide maintaining a coupling point for a clutch actuator over a selectable amount of wear on the 306 clutch face. In certain embodiments, the coating actuator 1002 is additional or alternatively self-adjusting, allowing the actuation volume to the actuator to remain consistent as the clutch, clutch coupling breech 808, linear actuator 1002 and / or other aspects of system wear and / or change over the life cycle of the transmission 100. In certain embodiments, the drive volume is consistently maintained as a volume of activation close to zero. In certain embodiments, the consistency of the drive volume and / or an almost zero maintained drive volume provides improved response time and improved control accuracy throughout the transmission life cycle 100 and
Petition 870190057036, dated 06/19/2019, p. 87/213
65/106 provides qualitative improvements in the operation of clutches, such as features that use the clutch quickly during shifts (for example, to mitigate tooth-tip events and / or reduce the impact of clearance on gear meshes).
[00144] The exemplary clutch operating set 3800 includes input shaft 204 and release bearing 1118, and the face of clutch 306 that engages the primary engine. The example clutch operating set 3800 further includes a diaphragm spring 3802 that polarizes the face of the clutch 306 to a engaged position (towards the pressing machine and away from the transmission 100) and after actuation by the clutch hitch fork 808 (for example, clutch coupling fork 808 pushed forward by clutch actuator 1002) removes clutch face 306 from the engaged position. Any other actuation mechanism for a clutch is contemplated in this document. Clutch operating set 3800 additionally includes a bearing housing 3804 that engages and retains release bearing 1118, and additionally includes a landing face on release bearing 1118 that engages clutch hitch fork 808.
[00145] Referring to Fig. 42, a portion of the 3800 clutch operating assembly is shown in exploded view. The clutch operating set 3800 includes clutch 106, having torsion springs 4202 and a pre-damper assembly 4006 coupled thereto. The clutch operating set 3800 includes a pressure plate assembly 4004 and the diaphragm spring assembly support 4002. Referring to Fig. 43, a detailed view of the exemplary pressure plate assembly 4004 is shown in a view in perspective (Fig. 43) and in a side section view (Fig. 44). The exemplary pressure plate set 4004 includes a
Petition 870190057036, dated 06/19/2019, p. 88/213
66/106 cam ring 4504 and control fingers 4506 coupled to a pressure plate 4508. Cam ring 4504 rotates and cooperates with control fingers 4506 to position clutch 106 in such a way that, once the face clutch wear 306, release bearing 1118 maintains the same position in relation to clutch hitch fork 808. Accordingly, even when clutch face 306 wears out, clutch actuator 1002 returns to the same position within the clutch housing. clutch actuator 104. After a selected amount of wear, control fingers 4506 prevent further adjustment and clutch actuator 1002 will not return to the starting point. Accordingly, a high degree of responsiveness and repeatability is provided when engaging the clutch on the exemplary transmission 100, allowing for the diagnosis and / or detection of wear on the clutch face 306, where the clutch still works, but the return position of the clutch actuator 1002 responds to wear on the clutch face 306. The exemplary pressure plate assembly 4004 includes a torsion spring (not shown) coupled to the meat ring 4504 to drive the rotation of the meat ring 4504 to the face of clutch 306 wears out, and a cam baffle 4510 which has teeth to prevent counter-rotation of cam 4504.
[00146] Several exemplary modalities of the present disclosure are described below. All examples are non-limiting and can be divided or combined, in whole or in part. Exemplary modalities may include any aspect of modalities throughout this disclosure.
[00147] Certain modalities of a high efficiency transmission are described below. The description of certain characteristics as promoters of transmission efficiency is provided as illustrative examples. Efficiency-promoting features can be included
Petition 870190057036, dated 06/19/2019, p. 89/213
67/106 trips in a particular mode, while other features may not be present. The efficiency-promoting features can be combined, used in part when applicable and subgroups of any one or more of the efficiency features can be included in certain modalities. The description of any resource or characteristic as an efficiency-promoting resource is not limiting any other resource in this disclosure, it also promotes efficiency and in certain modalities it will be understood that a resource can promote efficiency in certain contexts and / or applications and decrease efficiency in others contexts and / or applications.
[00148] An exemplary transmission 100 includes one or more housing elements 102, 104, 108 that are made at least partially from aluminum. In certain embodiments, the housing elements 102, 104, 108 can be cast aluminum. The use of aluminum introduces numerous challenges to the performance of a transmission 100 and, in certain embodiments, introduces more challenges in which transmission 100 is a high output transmission. For example, and without limitation, aluminum is usually not as strong as steel for a given volume of material, it is softer than steel and has different stress characteristics, making it less resistant to stress in certain applications. Changes in the tensioning functionality of the housing material have consequences during transmission - for example, bolt protrusions generally must be deeper for equivalent strength, and the housing shells must be thicker and / or have management capabilities. voltage to equivalent voltages experienced in the housing. Aluminum also does not isolate noise, as well as compensated materials such as steel.
[00149] The exemplary transmission 100 includes an energy impulse management arrangement that neutralizes, cancels, reduces
Petition 870190057036, dated 06/19/2019, p. 90/213
68/106 and / or redirects the primary energy impulse loads experienced within the transmission. In certain embodiments, the power impulse management arrangement redirects axial loads out of the gearboxes and / or transmission housings, allowing for reduced strength of the gearboxes with sufficient durability and robustness for a high output transmission. An exemplary energy impulse management arrangement includes helical gears in the power transfer line throughout the transmission 100, for example the countershaft gear screens 902, 904, where helical gear angles are selected to neutralize, reduce and / or redirect within transmission 100. Axial load adjustments can, in certain modalities, be improved or optimized for certain operating conditions, for example, gear ratios that are likely to be coupled with higher load conditions, gear ratios probably involved in higher speed differential operations on thrust bearings and the like. A gear coupling next to the input shaft 204 of the transmission 100 with the countershaft 902, 904 has one or more corresponding gear couplings on the first main shaft portion side 804 of the transmission 100 (depending on the available gear ratios and rail shift plane) and the impulse management aspects of helical gears include selected helix angles for the various gear meshes to adjust the impulse profile and the thrust cycle of the transmission 100. Some considerations in determining gear geometries helicals include, without limitation: the load cycle for the application, installation or vehicle (loads and / or speeds, as well as operating time), the gear ratios in each mesh and the duty cycle of opposite gear hitch scenarios , and noise and efficiency characteristics of heli gear ratio selections

69/106 coidal. One skilled in the art, which has the benefit of the present disclosure and information normally available on a contemplated system, can readily determine helical gear ratios to perform power impulse management operations on a 100 transmission. In certain embodiments, axial loads they are redirected to a thrust management device, such as an axial bearing, which is positioned between rotary axes with a lower speed differential (for example, the input shaft 204 for the first major axis portion 804). In certain embodiments, transmission 100 does not include tapered bearings.
[00150] An example of transmission 100 includes a low loss lubrication system. The losses, in the present case, refer to the general energy consumption of the lubrication system, regardless of the source of energy consumption, and including at least the pumping work performed by the lubrication system, viscous losses of moving parts in the transmission 100 and / or parasitic losses in the lubrication system. The exemplary low-loss lubrication system includes a dry well, in which the rotating portions of the transmission 100 (e.g., gears, shafts and countershafts) are not positioned, completely and / or partially, within the lubricating fluid in the reservoir. An exemplary lubrication pump assembly 1600, drawing lubrication fluid for the pump from the rear housing 108, provides a non-limiting example of a lubrication system having a dry reservoir. An exemplary low-loss lubrication system additionally includes a centralized lubrication pump, such that the lubrication paths within the transmission 100 have a reduced length and / or a reduced or optimized total length of the lubrication channels. An exemplary lubrication pump set 1600, integrated in the transmission 100 and coupled to a countershaft or other

70/106 rotating element of the transmission 100, provides a non-limiting example of a centralized lubrication system. In certain embodiments, the use of centralized lubrication tubes 1802 and / or 1804 provides short passages for lubrication channels. Additionally or alternatively, an exemplary transmission 100 includes a lubrication tube positioned within the first main shaft portion and / or second main shaft portion, having holes to provide a portion of the lubrication paths to one or more bearings and additionally or alternatively not include seals on the lubrication tube. In certain other embodiments, a low-loss lubrication system includes a lubrication pump driven by a high-speed countershaft, where the high speed of the countershaft provides a higher pump lubrication speed, thus allowing a smaller lubrication pump perform lubrication pumping operations, reducing both pumping losses and / or weight of the lubrication pump and / or 1600 associated lubrication pump set.
[00151] An exemplary transmission 100 includes one or more high speed countershafts 902, 904. The term high speed with reference to countershafts, as used in this document, should be understood broadly. In certain embodiments, a high-speed countershaft rotates at a speed similar to the input shaft 204 and / or the first main shaft portion 804, for example at the same speed, within +/- 5%, +/- 10 %, + / -15%, + / 20%, +/- 25% and / or within +/- 50% of the speed of the input shaft 204 and / or the first portion of the main axis 804. In certain embodiments, a high-speed countershaft has a relative speed greater than a countershaft in a displacement transmission for a similar application, where application similarity can be determined from considerations such as rated power,
Petition 870190057036, dated 06/19/2019, p. 93/213
71/106 torque, torque multiplication capacity and / or final load output and / or duty cycle. A speed that is a high relative speed for a displacement transmission includes, without limitation, a speed that is at least 10% higher, 20% higher, 25% higher, 50% higher, 100% higher, up to 200% higher and greater than 200% higher. In certain embodiments, the use of high-speed countershafts 902, 904 allows smaller devices to operate in response to the rotation speed of the countershafts, for example, a lubrication pump driven by a countershaft 902, 904. In certain embodiments , a PTO device driven by one of the countershafts can use the higher countershaft speed to improve performance. In certain embodiments, the use of high speed countershafts 902, 904 allows reductions of gears and bearing components, since the countershaft operates at a speed closer to the input shaft and / or the first speed of the portion main shaft than in a previously known transmission, providing lower loads on gears and gear bearings and / or providing faster gear changes with lower losses (less travel time and / or lower braking to approximate countershaft speed at hitch speed, for example, in a shift). In certain embodiments, the lower loads on the countershafts, due to the high speed configuration and / or a double load sharing configuration, allow the countershaft to be of a smaller size and / or weight. In certain embodiments, the double countershafts provide noise reduction, for example, the reduced size of the coupling components and / or lower coupling forces. In addition, or alternatively, the lower rotational inertia of the countershafts has a lower effect on the clutch speed during shifts, for example, by transferring the countershaft inertia to the clutch.
Petition 870190057036, dated 06/19/2019, p. 94/213
72/106 before clutch engagement, allowing for a faster and lower loss change event (for example, lower braking applied to slow system recoil).
[00152] In certain embodiments, a gear ratio at the front of the transmission 100 is lower compared to a gear ratio at the rear of the transmission 100. In certain embodiments, providing greater torque amplification at the rear of the transmission (for example, of the countershaft (s) for the second main input shaft portion 804) than in front of the transmission 100 (for example, from the input shaft 204 to the countershafts) provides more efficient energy transfer ( for example, less loss) than a more uniform torque amplification. For example, a total 4: 1 ratio provided as a 1: 1 first stage and a 4: 1 second stage for most of the exemplary transmissions 100 provides less power transfer loss than that of a first stage 2: 1 and a second 2: 1 step, while providing the same overall torque amplification. In certain modalities, a rear: frontal amplification ratio is greater than 1.5: 1, greater than 2: 1, greater than 2.5: 1, greater than 3: 1, greater than 3.5 : 1, greater than 4: 1, greater than 4.5: 1 and / or greater than 5: 1. For example, when a general torque amplification ratio of 5: 1 is desired, an exemplary transmission includes a 1.25: 1 front transfer and a 4: 1 rear transfer. The reasons and modalities described are non-limiting examples. Those skilled in the art with the benefit disclosed in this document will readily appreciate that, in certain modalities, high-speed countershafts facilitate lower front torque amplification ratios - for example, in a torque amplification ratio close to the unit (1) , the count of the gear teeth between the countershaft and the input shaft is also close to the unit and
Petition 870190057036, dated 06/19/2019, p. 95/213
73/106 te, gear sizes can be kept low if the countershaft rotates at a high rate of speed. In certain embodiments, a high-speed countershaft facilitates the selection of gear sizes to meet other restrictions, such as providing an interface to a PTO device, providing gear geometries within a transmission 100 to facilitate fabrication and assembly within a cast housing and / or to maintain gear outside diameters in a normal range. Gear sizes supplied within a normal range - that is, not restricted to being large on the input shaft 204 and / or on the countershaft 902, 904 due to torque amplification requirements - allow the control of torsional forces on the axles and on the gear clamping mechanisms (eg welds and / or synchronizing devices) and / or the control of a final geometric cover area of the housing (for example, main housing 102) to provide a compact and / or easily integrated transmission 100.
[00153] In certain embodiments, a double countershaft arrangement provides balanced forces on the input shaft 204 and / or the first main shaft portion 804 and lower cost bearings at one or more gear locations on the input shaft 204 and / or in the first main shaft portion 804 are provided - for example, a radial bearing, bushing, a washer and / or a bearing with rolling elements. In certain embodiments, a needle bearing is provided at one or more gear locations on the input shaft 204 and / or the main shaft portion 804, for example on a gear expected to receive a radial load, including, for example, a gear on input shaft 204 near the power input for transmission 100 and / or a gear coupled to the countershaft to power a PTO device.
[00154] In certain embodiments, helical gears in the
Petition 870190057036, dated 06/19/2019, p. 96/213
74/106 countershafts 902, 904 and the gear teeth in them provide high efficiency operation for the 100 transmission. For example, the helical gear provides thrust management control of the energy transfer in the transmission, allowing for smaller components weight and cost, such as bearings. In addition or alternatively, the control of thrust management of the gears allows to reduce the weight and / or the resistance of the frame for a certain transfer rate of power or torque. In addition or alternatively, the engagement of the helical gear allows a reduced noise generation, allowing a greater engagement force between the gears for a given noise level. In addition or alternatively, helical gears are easier to press and are time-related to, for example, spur gears - allowing for reduced manufacturing cost, improved manufacturing capacity and / or a more reliable gear mesh. In addition or alternatively, helical gears provide a greater contact surface for the gear teeth, allowing less contact pressure for a given contact force and / or less face width for the gear teeth, providing readily capable gear teeth withstand contact loads.
[00155] In certain embodiments, a transmission 100 is provided without tapered bearings in the transmission line. In certain embodiments, a transmission 100 has a reduced number of tapered bearings in the transmission line compared to a shift transmission in a similar application. Tapered bearings are normally used to control axial and radial loads. In certain embodiments, a transmission 100 includes features to control axial loads, so that tapered bearings are not present. Tapered rollers in a bearing require adjustment of bearing clearance and
Petition 870190057036, dated 06/19/2019, p. 97/213
75/106 of shims. In certain embodiments, the tapered bearings reduce the efficiency of energy transfer and generate additional heat in the transmission. In certain embodiments, the main bearings in a transmission example 100 are positioned (for example, pressed) on the housing elements 102, 104, 108 and the shafts in the transmission line are passed through them. An example of transmission 100 is mounted vertically, with shafts passed through the pressed bearings and where no play and / or bearing shims need to be made, the main housing 102 is coupled to the clutch housing 104 during vertical assembly and the rear housing 108 it is coupled to the main housing 102 to complete the housing portion of the vertical assembly. In certain embodiments, a transmission example 100 can be constructed horizontally or in another arrangement and / or vertically with the rear housing 108 downwards.
[00156] In certain embodiments, the energy transfer gears in the transmission 100 (for example, in the countershaft meshes) have a reduced height and / or have a flattened geometry at the top (for example, reference Fig. 24 - teeth have a flattened top profile). The use of shortened teeth provides sliding speeds on the gear teeth (for example, greater energy transfer efficiency), allowing the teeth to engage in a highly efficient energy transfer operation. Shortened gear teeth, when present, also experience less deflection than at the top of previously used gear tooth geometries, providing greater control of a noise source and longer gear tooth life. In certain embodiments, the use of helical gears with a flattened tooth geometry allows even more control of noise from flattened gear teeth and / or high power transfer loads. In certain modalities,
Petition 870190057036, dated 06/19/2019, p. 98/213
76/106 a low tolerance and / or high quality manufacturing operation for the gear teeth, such as the use of a worm screw to machine the gear teeth, provides a realized geometry of the gear teeth matching a design sufficiently to meet energy and noise transfer efficiency goals. In certain embodiments, a worm screw is used with a grinding and finishing grain applied in one pass, allowing the construction of the gear tooth to be completed in a single pass of the worm screw and leave a selected finish in gear tooth.
[00157] In certain embodiments, the transmission 100 includes axial loads canceled through a rolling bearing, to control the axial loads so that no bearing pressed on a housing shell receives an axial load, to control the axial loads so that one or more housing elements do not experience axial loads, to control axial loads so that a bearing positioned between low speed differential axles of the transmission (for example, between an input shaft 204 and a first main shaft portion 804) receives axial loads and / or so that axial loads are canceled and / or reduced by helical gears in energy transfer gear meshes. In certain embodiments, the bearings pressed into a housing element and / or one or more housing elements are directly exposed only to radial loads of energy transfer in the transmission 100.
[00158] In certain embodiments, a transmission 100 includes a PTO 410 interface configured to allow the engagement of a PTO device to one of the countershafts from a radial position, for example, at the bottom of the transmission 100. An example drive 100 includes gear settings so that a
Petition 870190057036, dated 06/19/2019, p. 99/213
77/106 radially extended gear of one of the countershafts 902, 904 is positioned to access the extended gear, so that a gear to drive a PTO device can be engaged with the extended gear. Additionally or alternatively, a corresponding gear on one of the input shafts 204 and / or the first main shaft portion 804 includes a needle bearing that accepts radial loads from the PTO coupling. In certain embodiments, countershafts 902, 904 do not include a PTO coupling gear (for example, at the rear of the countershaft) and transmission 100 is configured so that the transmission line gears can be used directly for PTO coupling. . Consequently, the size and weight of the countershafts are reduced in relation to the modalities with a dedicated PTO gear supplied on one or more countershafts. In certain embodiments, a second PTO access (not shown) is provided on the rear frame, so that a PTO device can alternatively or additionally engage the rear of the transmission. Consequently, in certain embodiments, a transmission 100 is configurable for multiple PTO coupling options (for example, selectable at the time of construction or order of a transmission), including an 8-bolt PTO access and / or is constructed to allow for multiple transmission options. hitch after construction (for example, both PTO access options provided, as with a plug on the rear over the rear PTO access and an installer / integrator being able to use one or both PTO access options).
[00159] An example of transmission 100 includes only a single driver connection for power drives in the transmission, for example, an air inlet port 302 provided in the integrated drive housing 112. A reduction in the number of connections reduces the integration and design, reduces leakage paths in the ins
Petition 870190057036, dated 06/19/2019, p. 100/213
78/106 and reduces the number of parts to be integrated and / or failures in the installed system. In certain embodiments, no external plumbing (for example, lubrication, coolant and / or other fluid lines) is present in transmission 100. In certain embodiments, transmission 100 is a non-cooling design, ensuring fewer failures in systems, making the 100 more robust transmission for an application or vehicle cooling system failure, reducing installation connections and integration design requirements, reducing leakage paths and / or failure modes in the transmission and installed vehicle or application and reducing the transmission weight size and footprint 100. It will be recognized that certain aspects of the transmission examples 100 throughout the present disclosure support a non-cooled transmission design, including at least improvements in transmission energy transfer efficiency (e.g. generating less heat within the transmission to be dissipated) and / or in the components aluminum s (eg, aluminum and common aluminum alloys are better thermal conductors than most steel components). In certain embodiments, the heat fins may be included in the housing elements 102, 104, 108 in addition to those represented in the illustrative embodiments of the present disclosure, in which additional heat rejection is desirable for a given application. In certain embodiments, an example of transmission 100 includes a refrigerator (not shown).
[00160] In certain embodiments, a transmission 100 includes a 306 organic clutch face. An organic clutch face provides consistent and repeatable torque engagement, but can be susceptible to damage from overheating. It will be recognized that certain aspects of the transmission examples 100 throughout the present disclosure support the use of an organic clutch face 306.
Petition 870190057036, dated 06/19/2019, p. 101/213
79/106
For example, the linear clutch actuator 1002 and the clutch adjustment for wear on the clutch face provide a highly controllable and repeatable clutch engagement, allow strict control of the clutch engagement and maintain the clutch life. In addition or alternatively, transmission components 100 that provide quick and smooth shifting couplings reduce the likelihood of using the clutch to shift organization events - for example, the use of high-speed countershafts, more rotational inertia countershafts lows, helical gears, efficient bearings (eg, shaft speed transient management in relation to tapered bearing modes) and / or compact short-term drives for changing gear with an integrated actuator set. In certain embodiments, the elements of the transmission 100 for quick and smooth shifting couplings improve the repeatability of the shifting events, resulting in a more consistent sense of direction in relation to a vehicle with an example of transmission 100 and additionally or alternatively the use of a 306 organic clutch face improves the ability to obtain repetitive change events that provide a consistent sense of direction.
[00161] In certain embodiments, a transmission 100 is configurable for a number of transmission ratios, such as an 18-speed configuration. An example of an 18-speed configuration adds another gear by engaging input shaft 204 with a corresponding gear on the countershafts. The compact length of the transmission examples 100 described in this document, combined with the modular configuration of the housing elements 102, 104, 108, allows immediate gears to be added to any of the axes and the accommodation of additional gears
Petition 870190057036, dated 06/19/2019, p. 102/213
80/106 within a single housing configuration and / or isolated changes to one or more housing elements, while other housing elements accommodate multiple gear configurations. An example of an 18-speed configuration is a 3x3x2 configuration (for example, three gear ratios available on the input shaft 204, three direct drive ratios on the first main shaft portion 804 and two transmission ratios available on the second main shaft portion 806). In addition or alternatively, other arrangements to achieve 18 gears or other gear configurations with more or less than 12 or 18 gears are contemplated in this document.
[00162] In certain embodiments, certain characteristics of a transmission example 100 allow the service of certain aspects of transmission 100 in a way that reduces the cost and service time in relation to previously known transmissions, as well as allowing the maintenance of certain aspects of the transmission 100 without performing certain operations that require expensive equipment and / or present additional risk (for example, loosening the transmission and / or disassembling the main portions of the transmission 100).
[00163] An example of service event 5600 (reference Fig. 45) includes an operation 5602 to access an integrated actuator set, directly accessing the integrated actuator set from an external location for transmission. In certain embodiments, the integrated driver assembly is positioned at the top of the main housing 102 and is accessed in a single unit with all shift and clutch drivers positioned on it. In certain embodiments, one or more actuators can be positioned outside the integrated driver assembly and a number of actuators can be positioned inside or coupled to the integrated driver assembly. Direct access to an integrated driver set provides,
Petition 870190057036, dated 06/19/2019, p. 103/213
81/106 in certain modalities, the ability to install, repair and / or maintain actuators without dropping the transmission, disassembling the main elements of the transmission (including at least the decoupling of one or more housings, clutch, any bearing, any gear and / or one or more axes). Additionally or alternatively, the 5600 service event example includes an operation 5604 to decouple only a single power input from the trigger, although in certain embodiments more than one power input from the trigger may be present and accessed. The 5600 service event example includes an operation 5606 to service the integrated driver assembly, such as, but not limited to, fixing, replacing, adjusting and / or removing the integrated driver assembly. The term service event, as used in this document, should be understood to include at least maintenance, integration, installation, diagnostics and / or access to a part to provide access to other parts in the transmission 100 or system (for example, vehicle or application) where the transmission is installed.
[00164] An example of service event 5900 (reference Fig. 46) includes an operation 5902 to access a radial bearing 2602 positioned at an engagement end of the input shaft 204. The engagement end of the input shaft 204 engages the motor main shaft, for example, on a roller bearing on the primary motor (not shown) and the engagement end of the input shaft 204 may experience wear. The inclusion of a bearing bearing 2602, in certain embodiments, provides ready access to replace this wear part without removing and / or replacing the input shaft 204. The service event example 5900 also includes an operation 5904 to remove the bearing radial 2602 and a 5906 operation to replace the radial bearing 2602 (for example, after fixing the radial bearing 2602 and / or replacing it with a different part). The example
Petition 870190057036, dated 06/19/2019, p. 104/213
82/106 of service event 5900 describes a radial bearing 2602 positioned on the input shaft 204, however, the radial bearing 2602 can be any type of wear protection device, including any type of bearing, bushing and / or sleeve.
[00165] With reference to Fig. 47, a perspective view of an example of clutch housing 104 consistent with certain embodiments of the present disclosure is illustrated. The clutch housing 104 includes an interface portion 4702 that allows coupling to a primary engine. The modularity of the clutch housing 104 allows for prompt configuration and integration for specific changes, for example by providing an extended or split input shaft to add a gear layer to the input shaft without significantly changing the coverage area of the transmission 100 or requiring a new design of other aspects of the transmission 100, while maintaining interfaces consistent with the primary engine.
[00166] With reference to Fig. 48, another perspective view of an example of clutch housing 104 is consistent with certain embodiments of the present disclosure. The clutch housing 104 includes a second interface portion 4808 that allows coupling to a main housing 102. The modularity of the clutch housing 104 allows for prompt configuration and integration for specific changes, for example providing an extended or split input shaft for adding a gear layer to the input shaft without significantly changing the coverage area of the transmission 100 or requiring a redesign of other aspects of the transmission 100, while maintaining interfaces consistent with the main housing 102. The clutch housing example 104 also includes holes 4802 for countershafts in a bulkhead (or casing) formed on the side of the main housing 102 of the clutch housing 104 and a hole 4804 for passing the input shaft through it. The

83/106 holes in the integral bulkhead 4802, 4804 provide a mounting of bearings and shafts and a ready assembly of the transmission 100.
[00167] With reference to Fig. 49, a perspective view of an example of rear housing 108 consistent with certain embodiments of the present disclosure is illustrated. The rear housing 108 includes an interface portion 4902 that allows coupling to a main housing 102. The modularity of the rear housing 108 allows for prompt configuration and integration for specific changes, for example, providing a rear PTO interface 5102 (see reference in Fig. 51) or other changes in the rear housing 108, without significantly changing the coverage area of the transmission 100 or requiring a new design of other aspects of the transmission 100. With reference to Fig. 50, another perspective view of the housing is shown rear 108. Rear housing 108 includes a transmission line interface 5002, for example, for coupling to a transmission shaft or other downstream component. Referring to Fig. 51, a perspective view of another example of rear housing 108 is shown, providing a rear PTO interface 5102.
[00168] With reference to Fig. 52, a perspective view of an example of lubrication pump set 1600 is illustrated consistent with certain embodiments of the present disclosure. The drive element 1712, coupling the lubrication pump 1704 to one of the countershafts, is visible in the perspective view of Fig. 52. The modularity of the lubrication pump set 1600 allows for prompt configuration and integration for specific changes, for example, providing an alternative design of the pump or gear ratio, while maintaining interfaces consistent with the rest of the transmission 100. Referring to Fig. 53, another perspective view of an example of mounting the lubrication pump 1600 is illustrated. A screen 1718 oil trap and 1720 screen retainer are

84/106 visible in the view of Fig. 53.
[00169] With reference to Fig. 54, a perspective view of a main housing example 102 consistent with certain embodiments of the present disclosure is illustrated. The example in Fig. 54 has a connector for a transmission control module, but the transmission control module is not installed. Main housing 102 includes interfaces 5402, 5404 (see the disclosure portion referenced in Fig. 56) providing interfaces consistent with rear housing 108 and clutch housing 104. A clutch driver housing 202, which can be attached or integrated with an integrated driver housing 112, is visible in the view of Fig. 54. With reference to Figure 55, a transmission control module 114 (transmission control module, TCM) and a TCM 5502 retainer (for example, a cover TCM 1402) are shown as installed in a transmission 100. With reference to Fig. 56, an 8-screw PTO interface 410 is shown, which may not be optionally present or capped, without affecting the coverage area or the housing interfaces main 102. Referring to Fig. 57, a bottom view of a main housing example 102 is illustrated, providing a clear view of an example of an 8-screw PTO interface 410. C Referring to Fig. 58, a perspective view of an example of main housing 102 is shown, including a driver interface 5802, in which drivers for shifting, clutch control and / or a friction brake can be installed. Accordingly, main housing 102 can accommodate various drive assemblies, including an integrated drive assembly, without changing the coverage area or interfaces of main housing 102 with the rest of transmission 100.
