    Petition 870170098597, of 12/15/2017, p. 8/32
    5/22 below.
    [0014] The differential bearing portion 32 can be arranged in the vicinity of the central portion 30. The differential bearing portion 32 can support components of the differential 22 and can also define a cavity which can receive at least a portion of the differential 22. according to at least one embodiment, the differential bearing portion 32 can be coupled to the central portion 30 in any suitable way, such as with one or more fasteners such as a screw.

    [0016] The differential 22 can be arranged in box 20.
    Petition 870170098597, of 12/15/2017, p. 9/32
    6/22 differential 22 can be configured to transmit torque to the vehicle's drive wheel assemblies and to allow the drive wheel assemblies to rotate at different speeds. An input fork 50, an input shaft 52, an annular gear 54 and an optional output fork 56 are shown in at least one of figures 1-3 to facilitate an abbreviated discussion of the operation of the differential 22.
    [0017] The input fork 50 can facilitate the coupling of the set of axles 10 to a torque source. For example, the input fork 50 can be coupled to a drive shaft which can be coupled to an output of a vehicle transmission. Alternatively, the input fork 50 can be coupled to a connecting shaft or a drive shaft which can be coupled to an output fork 56 of another set of axes or a transfer housing. The input fork 50 can be arranged on the input shaft 52, which is best demonstrated in figure 3.
    [0018] The input shaft 52 may be rotatably supported by one or more bearings which may be arranged in the differential carrier portion 32 of the housing 20. The input shaft 52 may be provided with or operationally connected to one or more intermediate gears which can be configured to provide torque for ring gear 54 and output fork 56, if applicable. For example, a pinion gear (not shown) may be provided at one end of the input shaft 52 o
    Petition 870170098597, of 12/15/2017, p. 10/32
    7/22 which may be disposed opposite the input fork 50. The torque that is provided for the input fork 50 and the input shaft 52 can be transmitted to the ring gear 54 by means of the pinion gear.
    [0019] The annular gear 54 can rotate around an axis 58 and can spread lubricant 44 which accumulates in the well portion 42 as it rotates. As will be discussed in more detail below, a lubricant 44 of said nature can be captured and temporarily retained or stored in a reservoir module 28 to reduce the volume of lubricant 44 in the well portion 42 under various operating conditions. Reducing the volume of lubricant 44 in the well portion 42 can reduce losses or frictional drag which can be exerted on the annular gear 54 by the lubricant 44 and can improve the fuel economy of the vehicle. Torque of the ring gear 54 can be transmitted to each axis 24 by means of differential 22.
    [0020] The differential 22 can be arranged in box 20 and can be configured to allow axles 24 to rotate at different speeds. The differential 22 can generally be arranged in the central portion 30 of the box 20. As best shown in figure 3, the differential 22 can include a first outlet gear 60, a second outlet gear 62, a housing 64, a crosshead 66 and a plurality of pinion gears 68.
    [0021] The first output gear 60 can be arranged in the vicinity of the first axis 24. For example, the first output gear 60 can extend around

    8/22 of an axis 58 and can have a central perforation. The central perforation may have a groove which can receive and engage with a corresponding groove on the first axis 24 to inhibit rotation of the first output gear 60 with respect to the first axis 24. The first output gear 60 can include a set of teeth which can cooperate with one or more pinion gears.
    [0022] The second output gear 62 can be spaced and disposed opposite the first output gear 60. The second output gear 62 can have the same configuration as the first output gear 60 according to one or more embodiments. The second output gear 62 can be arranged in proximity to the second axis 24 and can extend around an axis 58 and can have a central perforation. The central perforation may have a groove which can receive and engage in a corresponding groove on the second axis 24 to inhibit rotation of the second output gear 62 with respect to the second axis 24. The second output gear 62 may also include a set of teeth which can cooperate with one or more pinion gears 68. [0023] The housing 64 can receive various components of the differential 22. The housing 64 can be spaced from the housing 20, the first axis 24 and the second axis 24 to facilitate the rotation of the housing 64 with respect to at least one of said components. According to the embodiment shown, housing 64 has a two-piece construction which includes a first housing portion
    Petition 870170098597, of 12/15/2017, p. 12/32
    9/22 and a second housing portion 72. The area inside the housing 64 which can receive the crosshead 6 6 can be designated as differential nest 74.
    [0024] The first housing portion 70 can be configured to rotate with respect to box 20. For example, the first housing portion 70 can be rotatably arranged on a differential bearing 76 which can be arranged in box 20 and which can facilitate the rotation of the first housing portion 70 around axis 58. The differential bearing 76 can be mounted on the differential bearing portion 32 according to one or more embodiments. The first housing portion 70 can support the annular gear 54. The annular gear 54 can be fixedly arranged on the first housing portion 70 in any suitable manner, such as with one or more fasteners such as screws to inhibit rotation of the gear ring 54 with respect to the first housing portion 70. The first housing portion 70 can include an opening 78. The opening 78 can be configured as a through hole which extends along axis 58. The first axis 24 can extend through opening 78. In addition, the first outlet gear 60 can be rotatably arranged in aperture 78 so that the first outlet gear 60 can rotate about axis 58 with respect to the first housing portion 70.
    [0025] The second housing portion 72 may be arranged opposite the first housing portion 70. The second housing portion 72 may be fixedly
    Petition 870170098597, of 12/15/2017, p. 13/32
    10/22 arranged in the first housing portion 70 in any suitable manner, such as with one or more fasteners such as screws to inhibit rotation of the second housing portion 72 with respect to the first housing portion 70. The second housing portion housing 72 may be configured to rotate with respect to housing 20. For example, the second housing portion 72 may be rotatably arranged on a differential bearing 76 which may be arranged in housing 20 and may facilitate rotation of the second housing portion 72 around axis 58. The second housing portion 72 can include an opening 80. Opening 80 can be configured as a through hole which extends along axis 58. The second axis 24 can extend through the opening 80. In addition, the second output gear 62 can be rotatably arranged in the opening 80 so that the second output gear 62 can rotate around the axis 58 with respect to the second housing portion 72.
    [0026] The housing 64 and the differential nest 74 can be arranged between differential bearings 76. The differential nest 74 can receive gears and moving components such as the first output gear 60, the second output gear 62, the crosshead 66 and the pinion gears 68.
    [0027] Crosshead 66 may be arranged in housing 64 and may be configured to rotate around axis 58. Crosshead 66 may include a set of pins 90. Pins 90 may extend away from axis 58 and may be arranged along a first crosshead axis 92 and
    Petition 870170098597, of 12/15/2017, p. 14/32
    11/22 a second cross axis 94. The first cross axis 92 and the second cross axis 94 can intersect and can be arranged perpendicular to each other and perpendicular to axis 58 according to one or more embodiments. The ends of pins 90 can be received in housing 64 and can be spaced from housing 20 to not interfere with the rotation of differential 22. For example, pins 90 can be received between the first housing portion 70 and the second housing portion 72.
    [0028] One pinion gear 68 can be rotatably arranged on each pin 90. Each pinion gear 68 can be arranged on housing 64. According to at least one embodiment, two pinion gears 68 can rotate around pins 90 which extend along the first cross shaft 92 and two pinion gears 68 can rotate around pins 90 which extend along the second cross shaft 94. Each pinion gear 68 can include a set of teeth which can cooperate with the first output gear 60 and the second output gear 62.
    [0029] Axles 24 can transmit torque from differential 22 to a set of drive wheels. According to figures 1 and 2, two axes 24 are provided so that each axis 24 extends through a different arm cavity 46. The axes 24 can extend along and can rotate around the axis 58 through the differential 22. Each axis 24 can have a first end and a second end. The first end may be
    Petition 870170098597, of 12/15/2017, p. 15/32
    12/22 coupled to differential 22. The second end can be arranged opposite the first end and can be located outside the housing 20. An axle flange 100 can be arranged on the second end and can facilitate the assembly of a wheel end assembly and a set of traction wheels. An axle bearing (not shown) can be provided between the first end and the second end of the axle 24 to rotatively support the axle 24. The axle bearing can be located between the reservoir module 28 and the axle flange 100 according to with one or more embodiments. [0030] According to figure 2, at least one lubricant conduit 26 can be provided to drive lubricant 44 to a reservoir module 28. Lubricant conduit 26 can be configured to receive or capture lubricant 44 which is splashed or sprayed into the housing 20 by the differential 22. According to at least one embodiment, the lubricant conduit 26 or a portion thereof can be configured as a chute or as an open channel which can receive lubricant 44 which it is spread or sprayed by a rotating ring gear 54 or which drips downward on an inner surface of the central portion 30. Said chute or channel may be oriented upwards and generally away from the well portion 42 or may include an opening passage whose lubricant 44 can be received. The lubricant line 26 can also be designed to direct lubricant to the differential 22, but it can be spaced from the gear
    Petition 870170098597, of 12/15/2017, p. 16/32
    13/22 annular 54 so as not to interfere with the rotation of the annular gear 54 or remove lubricant 44 from the surfaces of the annular gear. The lubricant duct 26 can be configured to capture lubricant and provide captured lubricant to a reservoir module 28 when the vehicle is traveling above the limit speed. For example, the rotation speed of the ring gear 54 may increase as the vehicle accelerates. Increasing the rotational speed of ring gear 54 can change the spray profile of lubricant 44 which is spread or sprayed by ring gear 54 in box 20. Lubricant line 26 can be configured, positioned or oriented so that it is not captured or only an insignificant amount of lubricant 44 is captured below the speed limit and a significant amount of lubricant 44 is captured above the speed limit. The limit speed can be established based on the vehicle development test and the evaluation of the performance characteristics of the set of axles 10. As a non-limiting example, the limit speed can be a speed of approximately 30 mph (48 km / h). Therefore, the lubricant line 26 and the reservoir module 28 can be calibrated so that the level of lubricant 44 in the well portion 42 falls below the differential bearings 76 above the limit speed to contribute to reducing frictional drag on the annular gear. 54.
    [0031] Lubricant line 26 may extend to the
    Petition 870170098597, of 12/15/2017, p. 17/32
    14/22 along an inner surface of the central portion 30 and the arm portion 34 of the box 20 according to one or more embodiments. For example, the lubricant line 26 can be formed as a one-piece with box 20. Alternatively, lubricant line 26 can be provided as a separate component which can be coupled to box 20 in any suitable way, such as by welding. or with a fastener. In addition, a lubricant conduit 26 or a portion thereof may hang downwardly from the central portion 30 of the housing 20 towards a reservoir module 28 to facilitate the flow of lubricant 44 to a reservoir module 28.
    [0032] A lubricant conduit 26 can conduct lubricant 44 to one or more reservoir modules 28. For example, a singular lubricant conduit 26 may be provided which has opposite ends which end in different reservoir modules 28. Alternatively, a lubricant conduit 26 can provide lubricant 44 to a single reservoir module 28 as illustrated in the embodiment shown in figure 2. More specifically, in figure 2 two lubricant conduits 26 are provided which provide lubricant 44 for different reservoir modules 28. According to said embodiment, the lubricant conduit 26 can include a first end 110 and a second end 112.
    [0033] The first end 110 can be arranged in the
    Petition 870170098597, of 12/15/2017, p. 18/32
    15/22 cavity 40 of the central portion 30 to contribute to the capture of lubricant 44 as described above. At least a portion of the lubricant conduit 26 in the central portion 30 or in the vicinity of the first end 110 may include an upwardly oriented opening 114. According to figure 2, the opening 114 extends from the first end 110 to the second end 112. The opening 114 of said nature can be provided by removing an upper section of a pipe or tube according to a or more embodiments or by forming a gutter or channel in one piece with box 20 as discussed above.
    [0034] The second end 112 can be arranged opposite the first end 110. The second end 112 can be located in the arm portion 34 of the housing 20 and can end at or near the entrance of the reservoir module 28. A region in the vicinity of the second end 112 may be attached or may include an attached portion 116 to contribute to the retention of lubricant 44 in the lubricant conduit 26 as it is conducted to the reservoir module 28. For example, the attached portion 116 of the lubricant conduit 26 it can define a through hole through which lubricant 44 can flow. According to at least one embodiment, the attached portion 116 can start at the central portion 30 and can end at the reservoir module 28. Alternatively, the attached portion 116 it can be suppressed according to one or more embodiments.
    [0035] At least one module can be provided
    Petition 870170098597, of 12/15/2017, p. 19/32
    16/22 reservoir 28 to receive lubricant 44 and / or to temporarily contain or retain a volume of lubricant 44 which otherwise accumulates in the well portion 42. A reservoir module 28 can be at least partially arranged in at least an arm portion 34 of box 20. In addition, a reservoir module 28 can extend into the center portion 30 above well portion 42 as shown in figure 3.
    [0036] Figures 2 and 3 show an exemplary reservoir module 28. The reservoir module 28 can include a first end plate 120, a second end plate 122, a portion of tube 124 and a set of side plates 126 which can contribute to at least partially defining a reservoir cavity 128 which can be configured to hold or contain a volume of lubricant 44. According to figure 3, the reservoir cavity 128 is presented in the full state, but may contain a smaller volume of lubricant 44. The reservoir modules 28 can expel lubricant 44 due to fluidic pressure and not due to the use of a pump. In addition, reservoir modules 28 can be configured so that it is not necessary to provide a valve to control the flow of lubricant 44 through one or more outlets, reducing costs and eventual valve control components. [0037] The first end plate 120 can be oriented in the direction of the differential 22. The first end plate 120 can be spaced from the arm portion 34 and can be arranged in the central portion 30 according to a
    Petition 870170098597, of 12/15/2017, p. 20/32
    17/22 or more embodiments. The first end plate 120 can include a tube opening 130, a first outlet 132 and optionally a second outlet 134. [0038] The first outlet 132 can be configured as a through hole which can extend through the first outlet plate end 120 to reservoir cavity 128. The first outlet 132 can generally be arranged below the tube opening 130. The first aperture 132 can be sized to control the flow of lubricant 44 out of the reservoir cavity 128. For example, the first output 132 can be dimensioned so that the volume of lubricant 44 which flows out of the reservoir module 28 at reduced speeds (eg reduced differential rotational speeds) is less than the volume of lubricant 44 which flows out of the tank module 28 at high speeds (eg high differential rotational speeds). The first outlet 132 can direct or provide lubricant 44 for a differential bearing 76. For example, the first outlet 132 can be configured as a tube which extends from the first end plate 120 to the differential 22 and can have an end to which can be arranged in the vicinity of the differential bearing 76. The tube can extend essentially parallel to the axis 58 according to one or more embodiments.
    [0039] The second outlet 134 can be configured as a through hole which can extend through the first end plate 120 into the cavity of
    Petition 870170098597, of 12/15/2017, p. 21/32
    18/22 reservoir 128. The second outlet 134 can generally be arranged above axis 58, the tube opening 130 and / or the first outlet 132. The second outlet 134 can be configured to provide lubricant 44 for differential nest 74. For For example, the second outlet 134 can be configured as a tube which extends from the first end plate 120 to the differential 22 and can have an end which is arranged in the vicinity of housing 64. The second outlet 134 can be provided in a reservoir module 28 which is oriented towards the teeth of the annular gear 54 according to one or more embodiments. The lubricant 44 can flow through the opening 78 between the axis 24 and the housing 64 to the differential nest 74. The second outlet 134 can extend essentially parallel to the axis 58 according to one or more embodiments.
    [0040] Second outlet 134 can be provided with a single reservoir module 28 so that lubricant 44 from second outlet 134 can flow to differential nest 74 to provide fresh lubricant by spreading lubricant out of differential nest 74. Provide a second outlet 134 with multiple reservoir modules 28 can result in lubricant streams which can oppose each other, which can trap lubricant in a differential nest 74 and inhibit spreading of lubricant from differential nest 74, which can reduce efficiency lubrication.
    [0041] The second end plate 122, which is
    Petition 870170098597, of 12/15/2017, p. 22/32
    19/22 best shown in figure 1, can be arranged at an opposite end of the reservoir module 28 of the first end plate 120. The second end plate 122 can engage with one or more surfaces of the arm portion 34 to contribute to the positioning of the reservoir module 28. The second end plate 122 can optionally include an outlet configured to provide lubricant 44 for an axle bearing. [0042] The tube portion 124 may extend from the first end plate 120 to the second end plate 122 and may be spaced from the axis 24. According to at least one embodiment, the tube portion 124 generally it may extend along axis 58 and may have a generally cylindrical configuration. According to at least one embodiment, the tube portion 124 can be configured to flex with respect to the axis 24 to facilitate installation. For example, tube portion 124 can be manufactured from a flexible material, such as a polymeric material such as plastic, rubber or synthetic rubber such as neoprene. In addition, lubricant 44 can also pass through tube portion 124 to provide lubricant 44 for an axle bearing. For example, lubricant 44 can spread to and flow along tube portion 124 or it can be transported along axis 24 through tube portion 124 towards the second end plate 122 and can flow from axis 24 or a reservoir module 28 to lubricate an axle bearing or components which may be located
    Petition 870170098597, of 12/15/2017, p. 23/32
    20/22 out of the second end plate 122.
    [0043] According to figures 2 and 3, the set of side plates 126, when provided, may include one or more members which at least partially define one side of the reservoir module 28. Each side plate 126 can extend from the first end plate 120 to the second end plate 122. According to at least one embodiment, each side plate 126 can be arranged adjacent and engaged with at least another side plate 126. According to the embodiment shown, four side plates 126 are provided which engage with at least two other side plates 126 to provide a box-like configuration in which opposite pairs of side plates 126 are arranged essentially parallel to each other. Therefore, the reservoir cavity 128 can be disposed between the side plates 126 and the tube portion 124, providing an attached cavity which allows the reservoir cavity 128 to extend around the ring-like axis 24. A configuration of said nature can facilitate the storage of lubricant without increasing the box 20 or the arm portions 34 in order to increase the volume or the space available in the box 20. One or more of the side plates 126 can be suppressed and the portion arm 34 of the box 20 can define a portion of the reservoir module 28 according to one or more embodiments.
    [0044] The reservoir module 28 may also include an inlet 140 which receives lubricant 44 from
    Petition 870170098597, of 12/15/2017, p. 24/32
    21/22 lubricant duct 26. The lubricant duct 26 can be arranged in the vicinity of inlet 140 or extend into the inlet 140 according to one or more embodiments. Inlet 140 can be configured as a through hole and can be provided on the first end plate 120 or on a side plate 126 according to various embodiments. According to the embodiment shown in figure 2, the inlet 140 is arranged on the side plate 126 which is located on top of the reservoir module 28 and in the vicinity of the first end plate 120.
    [0045] The set of shafts 10 can allow passive lubrication of internal components due to the rotation of the annular gear 54 or the operation of the set of shafts 10. In addition, lubricant 44 can be continuously driven through the reservoir module instead of be stored in a reservoir due to the closing of a valve to prevent the lubricant from flowing out of an outlet, which can promote a more homogeneous lubricant temperature compared to long-term lubricant storage in a tank in which the temperature lubricant may increase and imply periodic compensations to equalize the lubricant temperature.
    [0046] The exemplary embodiments described above do not describe all possible embodiments of the present invention. The words used in the specification are words of description and not of limitation
