    DETAILED DESCRIPTION [0009] As required, detailed embodiments of the present invention are disclosed herein; even so, it is important to note that the embodiments disclosed here are merely exemplary of this invention, which can be carried out in many different alternative ways. Figures are not necessarily to scale, and certain characteristics may be exaggerated while others will be minimized, in order to show details of particular components. Accordingly, specific functional and structural details that are disclosed herein should not be taken into account as being limiting, but merely as a representative basis for making known to those skilled in the art various ways of using the present invention.
    [0010] Referring to figure 1, an example of axis 10 can be seen in it. This set of axle 10 may be equipped with a motor vehicle, such as a truck, a bus, agricultural equipment, military transport or an armed vehicle, or with equipment for loading cargo in means of land transport, aquatic and aerial.
    [0011] The 10 axle assembly may transmit torque to one or more traction wheel assemblies, which may include a tire mounted on a wheel. In one or more embodiments, that axis 10 assembly may be steerable. The set of axle 10 can receive the torque of a component of a transmission train of a motor vehicle, as is the case,
    Petition 870180153351, of 11/21/2018, p. 8/31
    5/21 for example, an internal combustion engine and / or a transmission. Thus, for example, this set of shaft 10 may receive the torque of a transmission through a transfer box 12. This transfer box 12 may be coupled to the transmission by means of a drive shaft, and may be coupled to an intake 14 of the shaft assembly 10 by means of a drive shaft 16. This transfer box 12 may include a transfer box clutch 18, which may enable or prevent the transmission of torque from transfer box 12 to the shaft assembly 10. Therefore, the torque cannot be transmitted to the shaft assembly 10 through the drive shaft 16 when the transfer box clutch 18 disconnects or disables the transmission of torque from the transfer box 12 to the shaft assembly 10.
    [0012] Referring to figures 1-3, the axle assembly 10 may include an axle cover 20, a differential 22, a front axle sleeve 24, at least one axle 26 and a wheel end assembly 28.
    [0013] The cover of the axle 20 can receive various components of the set of the axle 10. On the other hand, this cover of the axle 20 can facilitate the assembly of the set of the axle 10 in the vehicle. This shaft cover 20 can define a cavity that can receive at least a part of the differential 22.
    [0014] This differential 22 may be configured in order to transmit torque to the vehicle's drive wheel assemblies and also to allow these drive wheel assemblies to rotate at different speeds. As in figure 1 the
    Petition 870180153351, of 11/21/2018, p. 9/31
    6/21 differential 22 is hidden by the cover of axle 20, then we will give a brief explanation of the operation of differential 22. This differential 22 may include a pinion and a differential crown. As previously mentioned, the pinion may be coupled to at least one source of torque, such as, for example, a transmission train for a component of a motor vehicle, as in the case of transfer box 12, through inlet 14. This pinion can support itself, in order to be able to rotate, in one or more bearings, being able to rotate around an axis. The torque that is transmitted to the pinion can be transmitted to the differential ring. Torque may be transmitted from the differential crown to each of the front axle sleeves 24 and from each of these front axle sleeves 24 to a corresponding wheel end assembly 28 and a corresponding drive wheel assembly.
    [0015] A part of each of the front axle sleeves 24, at least, may be rotated around an axle 30 by the differential 22. Each of the front axle sleeves 24 may have a first end and a second end. The first end may be coupled to differential 22. The second end may be positioned opposite the first end, and may be located outside the cover of shaft 20. In more specific terms, the second end may extend through of a hole that may exist at one end of a part constituting an arm of the axle cover 20. The front axle sleeves 24 may or may not be configured for use with an independent suspension system. So, for example, a
    Petition 870180153351, of 11/21/2018, p. 10/31
    7/21 front axle sleeve 24 that has been configured to be used with an independent suspension system may have several axle segments and / or axle joints, such as, for example, constant speed joints that facilitate the relative movement between the differential 22 and a wheel end assembly 28. Alternatively, a front axle sleeve 24 may be configured as a solid or live axle, which may not have an independent suspension system. An axle bearing may be installed between the first and second ends of the front axle sleeve 24 so as to support the front axle sleeve 24 so that it can rotate.
    [0016] Axis 26 may be connected to the cover of axis 20. As a general rule, axis 26 may extend along axis 30, and it cannot rotate around that axis. The axle 26 may define an orifice 40, through which the front axle sleeve 24 extends. Therefore, that axle 26 may be installed at a distance from the front axle sleeve 24, in order to allow the front axle sleeve 24 to rotate around the axle 30. As figure 3 shows more clearly, the axle 26 can support one or more wheel bearings 42 which, in turn, support the wheel end assembly 28 so that that end can rotate, as will be explained in more detail below. In addition, one or more sets of brake shoes 44 may be installed at a certain distance from the axle 26, in order to prevent the rotation of an associated wheel hub assembly 28. A set of brake pads 44 can be part of a friction brake
    Petition 870180153351, of 11/21/2018, p. 11/31
    8/21 which may have been configured either as a drum brake or as a disk brake.
    [0017] Referring to figures 2 and 3, the wheel end assembly 28 may couple the front axle sleeve 24 to a traction wheel assembly, which may include a tire mounted on a wheel. In these figures, the wheel end assembly 28 has been configured to have a drum brake configuration, and a disk brake configuration can also be used. The wheel end assembly 28 may include a hub 50, a brake drum 52, a cover 54, a crosshead assembly 56, a bearing 58, a thrust bearing 60, a clutch ring 62 and one or more members of diversion 64. In a disc brake configuration, and as is known to those skilled in the art, the brake drum 52 may be replaced by a rotor.
    [0018] Hub 50 may be installed on axis 26 in order to be able to rotate. Thus, for example, one or more wheel bearings 42 may be mounted on the axle 26, and can support the hub 50 so that it can rotate. The cube 50 may have a first surface 70, a second surface 72 and a third surface 74. The first surface 70 may face away from differential 22. In at least one embodiment, that the first surface 70 may extend in the opposite direction to that of axis 30, and may also be arranged radially in relation to axis 30. The second surface 72 may be some distance from the first surface 70. In addition, this second surface 72
    Petition 870180153351, of 11/21/2018, p. 12/31
    9/21 may also extend in the opposite direction to and / or extend radially in relation to axis 30. The second surface 72 may include one or more cavities 76 which may receive a deviation member 64, as will be explained in more detail below . The third surface 74 may extend from the first surface 70 to the second surface 72. The third surface 74 may include a groove of cube 78 which, in turn, may have several teeth, which may extend in one direction basically parallel to axis 30.
    [0019] The hub 50 may also include a passage 80. That passage 80 may facilitate the flow of pressurized fluid to actuate the clutch ring 62, as will be explained in more detail below. The passage 80 can be, at least partially, defined by a conduit or a tube, which can be installed outside the cube 50, and in one or more embodiments they can extend through the cube 50 and / or coverage 54.
    [0020] Brake drum 52 may be fixedly installed on hub 50. That brake drum 52 may extend around brake shoe assemblies 44 and may, at least partially, define an outer surface of the end assembly wheel 28. Figures 1 and 2 show a drum brake configuration; however, a disk brake configuration may be used in one or more embodiments.
    [0021] Cover 54 may be fixedly installed on cube 50. Cover 54 may act in conjunction with the
    Petition 870180153351, of 11/21/2018, p. 13/31
    10/21 hub 50 in order to define a cavity 84 for receiving the crosshead assembly 56. In at least one embodiment, the cover 54 may be installed at one end of the wheel end assembly 28 adjacent to the drum brake 52, to help hide the crosshead assembly 56, and also at one end of the front axle sleeve 24, in order to prevent contaminants from entering. In at least one embodiment, the cover 54 may include a hole in the cover 90, plus a final surface 92, an inner surface 94 and a cavity for the clutch ring 96.
    [0022] The hole in the cover 90, which can be seen more clearly in figure 2, may be positioned along the axis 30 and, in addition, it may be positioned near the end of the sleeve of the front axle 24. if desired, a plug 100 may be installed in the hole in the cover 90. In at least one embodiment, the plug 100 may include threads that engage with corresponding threads in the hole in the cover 90.
    [0023] The final surface 92 may face the cube 50. The inner surface 94 may extend from the final surface 92 in a direction that extends in the opposite direction to differential 22. Therefore, the inner surface 94 may face for axis 30, being able to be positioned radially in relation to that axis.
    [0024] The cavity for the clutch ring 96 may receive the clutch ring 62. The cavity for the clutch ring 96 may extend from the final surface 92, which may be
    Petition 870180153351, of 11/21/2018, p. 14/31
    11/21 positioned between the inner surface 94 and an outer surface existing opposite the inner surface 94, and positioned at a distance from these surfaces. This cavity for the clutch ring 96 can be configured as a ring, and it can also extend around the axis 30.
    [0025] Passage 80 may extend through cover 54 such that the portion of passage 80 in cover 54 may be connected, by means of fluid, with the portion of passage 80 in hub 50. Passage 80 may be extend from the final surface 92 to the cavity for the clutch ring 96. At the interface between the cover 54 and the hub 50 adjacent to the passage 80, a seal 102, such as one or more O-rings, may be installed for prevent leakage of a pressurized fluid, as will be explained in more detail below.
    [0026] As a general rule, crosshead assembly 56 may be installed in cavity 84. With clutch ring 62 in its first position, and as will be described in more detail below, crosshead assembly 56 may transmit torque from the front axle sleeve 24 to hub 50. In addition, the crosshead assembly 56 may provide a reduction in speed between the front axle sleeve 24 and the drive wheel installed on hub 50. In at least one embodiment , the crosshead assembly 56 may include a crosshead 110, a hub reduction gear set 112 and a crosshead box 114.
    [0027] This so-called crosshead 110 can rotate around the axis
    Petition 870180153351, of 11/21/2018, p. 15/31
    12/21
    30. The crosshead 110 may have a central hole which can receive the front axle sleeve 24 and which can be positioned at a certain distance from that sleeve. This crosshead 110 may include a set of pins 120. Pins 120 may extend in the opposite direction to the central hole, and may also be arranged along a first axis 122 and a second axis 124. These first axis 122 and the second axis 124 will be able to intercept each other, and may also be positioned so that they are essentially perpendicular to each other and also basically perpendicular to axis 30. The ends of pins 120 may be accommodated in the crosshead box 114, and may also be positioned at a certain distance of the cover 54, so as not to interfere with the rotation of either the cover 54 or the cube 50. Alternatively, in one or more embodiments, a smaller number of pins 120 may be provided. two pins 120, each receiving a reduction gear from hub 112.
    This hub reduction gear set 112 may include a front axle sleeve gear 130, an axle gear 132 and a pinion gear set 134.
    [0029J The front axle sleeve gear 130 may be fixedly installed on the front axle sleeve 24. This front axle sleeve gear 130 may include, for example, a hole which, in turn, has a spline that engages with a corresponding spline of the front axle sleeve 24. Therefore, the axle sleeve gear
    Petition 870180153351, of 11/21/2018, p. 16/31
    Front 13/21 130 can rotate together with the front axle sleeve 24.
    [0030JA Axle gear 132 may be fixedly installed on axis 26. Thus, for example, axle gear 132 may include the hole with a spline that engages with a corresponding spline on axis 26. It may also be installed an anti-rotation pin 140 to prevent rotation of an adjustment nut with respect to axis 26.
    [0031] Each of the pins 120 may have a pinion gear 134, installed in order to be able to rotate. As a general rule, each pinion gear 134 may be installed in the crosshead box 114, and may be attached to a corresponding pin 120, with one or more fixing devices, as is the case, for example, of a first washer 142, of a second washer 144 and a thrust bearing 146. In at least one embodiment, two pinion gears 134 may rotate around pins 120 extending along the first axis 122, while two pinion gears 134 may rotate around pins 120 extending along the second axis 124. Each pinion gear 134 may include a set of teeth that engages either the front axle sleeve gear 130 or the axle gear 132. In addition , a set of roller bearings may be installed between the pinion gear 134 and each of the pins 120, in order to facilitate the rotation of a pinion gear 134.
    [0032J the crosshead box 114 may be installed in the cavity 84. That crosshead box 114 may include several slots 148 that may receive a corresponding pin 120 from
    Petition 870180153351, of 11/21/2018, p. 17/31
    14/21 crosshead 110. In this way, crosshead box 114 can rotate around axis 30 with crosshead 110. To facilitate assembly, grooves 148 can be opened at one end or on one side of the crosshead box. 114 which faces the cover 54. The crosshead box 114 may also include a splined crosshead box 136. This splined crosshead box 136 may be installed along an outer circumferential surface of the crosshead box 114. The crosshead box splined 136 may include several teeth, which may extend basically parallel to axis 30. Alternatively, this splined crosshead box 136 may be replaced by a face gear configuration, which may selectively engage , on a gear with a matching face installed on the clutch ring 62.
    [0033] Bearing 58, if installed, may facilitate rotation of the crosshead box 114 in relation to the cover 54. This bearing 58 may be installed between an outer circumferential surface of the crosshead box 114 and the internal surface 94 of the cover 54. In addition, this bearing 58 may also be characterized by any configuration that is suitable. Thus, for example, bearing 58 may be configured as a set of roller bearings that may be arranged radially around axis 30.
    [0034] The thrust bearing 60, if any, may be installed between the hub 50 and the crosshead box 114. This thrust bearing 60 can be configured in order to prevent the movement of the crosshead box 114 in relation to the hub 50. The
    Petition 870180153351, of 11/21/2018, p. 18/31
    15/21 thrust bearing 60 may have a configuration similar to that of a ring, and may be radially disposed in relation to axis 30. Thus, for example, that thrust bearing 60 may
    be installed between the 26 axis and the cube 50 and / or the member of deviation 64. [0035] 0 ring clutch 62, in turn, may be installed between the cube 50 and a Cashier in crosshead 114. A
    the configuration of that clutch ring 62 may, in general terms, be that of a ring, which may extend around axis 30. In addition, clutch ring 62 may move either axially or along axis 30, between its first position and its second position, in order to couple and uncouple the crosshead assembly 56 and the hub 50. In the embodiment shown in figures 2-4, it can be seen that the clutch ring 62 it has several chills that facilitate its coupling. Alternatively, one or more of these chills can either be replaced, or supplemented, with a face sprocket configuration, which can be achieved by the presence of one or more gear teeth along surfaces of the clutch ring 62 and / or the crosshead box 114, which may be facing each other and which may extend radially in relation to axis 30.
    [0036] The clutch ring 62 may have an outer surface 150, an inner surface 152, a first end 154, a second end 156 and still have one or more seals 158 installed.
    [0037] The outer surface 150 may face the
    Petition 870180153351, of 11/21/2018, p. 19/31
    16/21 direction opposite that of axis 30. The outer surface 150 may include a first groove 160. That first groove 160 may be positioned in the vicinity of the first end 154. In addition, this first groove 160 may also include several teeth, which they may be arranged so as to be positioned basically parallel to axis 30 and along that axis. The first spline 160 may be engaged with the hub spline 78 in order to prevent rotation of the clutch ring 62 in relation to the hub 50 and, at the same time, to allow axial movement or movement along axis 30.
    [0038] The inner surface 152 may be located opposite the outer surface 150. That inner surface 152 may include a second groove 162. That second groove 162 may be placed in the vicinity of the first end 154. Thus, for example, this second groove 162 may extend from the first end 154 to the second end 156. That second groove 162 may include several teeth, which may be arranged so as to be positioned basically parallel to axis 30 and along that axis. The second spline 162 may be engaged with the splined crosshead box 136 when the clutch ring 62 is in its first position. The second spline 162 can disengage the spline crosshead box 136 when the clutch ring 62 is in its second position.
    [0039] The second end 156 may be placed opposite the first end 154. That second end 156 may be lodged in the cavity for the ring
    Petition 870180153351, of 11/21/2018, p. 20/31
    17/21 clutch 96.
    [0040] One or more seals 158, such as, for example, O-rings, may be installed between the clutch ring 62 and the cover 54, in order to prevent leakage of pressurized fluid from the cavity to the clutch ring 96.
    [0041] One or more bypass members 64 may extend from hub 50 to clutch ring 62. Although figure 2 shows four bypass members 64, a greater or lesser amount than That. These bypass members 64 can tilt the clutch ring 62 towards its first position. Each bypass member 64 may be accommodated in a receptacle 76 on hub 50. Bypass members 64 may engage with hub 50 and clutch ring 62. In at least one embodiment, a bypass member 64 can be configured as a spring.
    [0042] An actuator 170 may be installed to move the clutch ring 62 from its first position to its second position. In at least one embodiment, that actuator 170 may include a source of a fluid under pressure 172, responsible for supplying a fluid under pressure to actuate the clutch ring 62. In one or more embodiments, this fluid under pressure may be either a gas, such as air, or a liquid, such as a hydraulic fluid. That fluid under pressure may be supplied to the clutch ring 62 via passage 80. There may also be a control valve 174 for controlling the flow of fluid under pressure from the source of a fluid under pressure 172 to the clutch ring
    Petition 870180153351, of 11/21/2018, p. 21/31
    18/21
    62. This control valve 174 will also be able to control the ventilation of that fluid under pressure, in order to allow the clutch ring 62 to move from its second position to its first position under the effect of the bypass force being exerted by the members of deviation 64.
    [0043] The performance of the clutch ring 62 will be better understood taking into account figures 3 and 4. Although these figures 3 and 4 illustrate an embodiment that does not have an interface consisting of a face gear installed between the clutch ring 62 and the crosshead box 114, the operating principles are similar to the operating principles applicable when using such a face sprocket configuration. The activation of the clutch ring 62 can be achieved either through manual intervention or automatically, using control logic that can be based on the vehicle's operating parameters.
    [0044] Figure 3 shows the clutch ring 62 in its first position. In that first position, clutch ring 62 couples crosshead box 114 to hub 50. In more specific terms, clutch ring 62 registers an offset to the left of the perspective shown in the figure, so that the second spline 162 engages in spline crosshead box 136 which is installed in crosshead box 114. In addition, the first spline 160 of clutch ring 62 engages with hub spline 78. Therefore, clutch ring 62 engages crosshead box 114 to hub 50, so that crosshead box 114 and hub 50 can rotate together around axis 30. On the other hand, torque that is transmitted
    Petition 870180153351, of 11/21/2018, p. 22/31
    19/21 to the axle assembly 10 can be transmitted by the front axle sleeve 24 to the hub 50 through the crosshead assembly 56 and the clutch ring 62.
    [0045] In figure 4, the clutch ring 62 is shown in its second position. In that second position, that clutch ring 62 decouples crosshead box 114 from hub 50. In more specific terms, clutch ring 62 is moved to the right of the position shown in figure 3, so that the box grooved crosspiece 136 does not engage the second groove 162. The clutch ring 62 may move to its second position when the deflection force exerted by the actuator 170 overlaps the deflection force that is exerted by the deviation members 64. In more specifically, control valve 174 may be actuated to allow fluid under pressure to flow through passage 80 into the cavity for clutch ring 96. Therefore, clutch ring 62 may move in a way that the second spline 162 disengages the splined crosshead box 136. The first spline 160 may remain engaged with the hub spline 78 as the clutch ring 62 moves from its first position to its position. second position.
    [0046] In this second position, hub 50 may rotate independently of the front axle sleeve 24 and crosshead assembly 56.

    Petition 870180153351, of 11/21/2018, p. 23/31
    20/21 crosshead assembly 56. In the second position, the transfer box clutch 18 may be positioned so that no torque is transmitted from the transfer box 12 to the intake 14 of the shaft assembly 10. This disengagement clutch release transfer box 18, combined with displacement of clutch ring 62 to its second position, helps to isolate components of the axle assembly 10, such as the differential crown and differential pinion 22, front axle sleeves 24 and gears of the crosshead assembly 56, so that these components can remain stationary, without rotating. As a result, the noise produced by the axle assembly 10 can be reduced, as these components are not being rotated, or driven, by the rotation of the wheel assembly and hub 50. This type of configuration can be used to reduce noise levels when a vehicle is being operated in a two-wheel drive mode where no torque is provided to the axle assembly 10, which can improve fuel savings. On the other hand, decoupling can be installed either at the end of the axle support of the front axle sleeve, or at the intake for the axle assembly, or in a transfer box.
