An axle assembly having a support bearing assembly. The support bearing assembly may be mounted to a differential carrier and may engage a back side of a ring gear. The support bearing assembly may rotatably support the ring gear and may inhibit deflection of the ring gear away from a drive pinion.

A differential bearing arrangement is provided for supporting a differential cage, having a final drive housing, at least one bearing support and at least one fastening screw with a screw head and a cylindrical screw body that is provided with an external thread and fixedly connects the bearing support to the final drive housing. The bearing support has a blind hole with an internal thread and the fastening screw is arranged such that the screw head thereof comes to bear against an outer surface of the final drive housing, and the screw body extends through a through-recess formed in the final drive housing and is at least partially received by the blind hole formed in the bearing support. The internal thread of the blind hole cooperates with the external thread of the fastening screw.

A power transmitting component that includes a housing, a case, a bearing, a bearing adjuster, and a retaining member. The housing defines a bearing bulkhead and an aperture, the aperture being disposed about a first axis. A pinion is coupled to the housing for rotation about a second axis that is not coincident with the first axis. A ring gear is coupled to the differential case and is meshed with the pinion. A bearing supports the case for rotation relative to the housing about the first axis. A bearing adjuster is disposed within the aperture and abuts the bearing. The retaining member is formed of a polymeric material and couples the bearing adjuster to the bearing bulkhead such that the bearing adjuster is non-rotatably and axially fixed to the housing and a preload is applied to the bearing in a direction along the first axis.

A differential for a vehicle includes a final drive gear with a final drive gear spline, a differential carrier with a differential carrier spline, and an axially slidable clutch. The axially slidable clutch includes a first clutch spline drivingly engaged with a one of the final drive gear spline or the differential carrier spline and a second clutch spline for selectively drivingly engaging with the other one of the final drive gear spline or the differential carrier spline. In an example embodiment, the differential also includes a pair of side gears, each including an inner spline for drivingly engaging a respective axle shaft, a pair of radially offset spider gears, each drivingly engaged with both of the side gears, and a shaft extending through the pair of radially offset spider gears into the differential carrier.

An axle assembly that includes a housing assembly, an input pinion, a ring gear, a ring gear bearing, and a differential assembly having a differential case. The ring gear bearing supports the ring gear for rotation on the housing assembly as well as handles thrust loads between the ring gear and the housing assembly in opposite axial directions. The ring gear bearing includes an outer bearing race having a first race member, which may be unitarily and integrally formed with the ring gear, and a second race member that is received in a groove formed on the ring gear. The differential case is coupled to the ring gear and secures the second race member to the ring gear.

A differential gear assembly, in particular for a motor vehicle, includes a gearwheel, driven by a pinion and arranged on a differential case that is rotatably mounted in a gearbox case via rolling-contact bearings on both sides. Planet gears are supported in the differential case on at least one driving pin and meshing with axis-parallel output gears on output half-shafts. The gearwheel is attached to the differential case without form fit in circumferential direction and has recesses into which the at least one driving pin formfittingly projects in circumferential direction.

A transmission assembly for an electric drive for a motor vehicle comprises a first transmission unit having a drive gear and a driven gear; a second transmission unit which is drivingly connected to the first transmission unit and which features a transmission speed reduction ratio i2; a third transmission unit which is drivingly connected to the second transmission unit and which transmits an introduced torque from an input part to two output parts; wherein the second transmission unit comprises a planetary gearing with a planetary gear, a planetary carrier, a first sun gear and a second sun gear, wherein the planetary gear engages the first sun gear and the second sun gear, wherein the first sun gear is at least rotatably supportable relative to a stationary component and wherein the second sun gear is drivingly connected to the input part of the third transmission unit. An electric drive assembly can have such a transmission assembly.

An axle assembly having a drive pinion that may be rotatably supported by first and second sets of roller bearing elements. A preload element may exert a preload force on at least one of the first and second sets of roller bearing elements. The preload element may be disposed on the drive pinion in an inboard direction from the yoke.

Various improvements to axle assemblies are disclosed herein that are especially adapted for highly robust and compact configurations for use in front (i.e., steering) axle configurations.

A final drive device includes a housing and a final drive gear mechanism. The final drive gear mechanism is provided in the housing, and comprises a drive pinion and a ring gear meshed with the drive pinion and a differential gear mechanism. The differential gear mechanism includes a pinion rotatably supported by a pinion mate shaft, and a pair of side gears meshed with the pinion from both sides in an axle direction. The final drive device has a pinion carrier that is rotated in a direction around the axle integrally with the pinion mate shaft supporting the pinion, and which is secured to the ring gear. The pinion carrier is provided with a pinion housing unit that houses the pinion while permitting the pinion to rotate around its own axis. The side gears are fixedly located relative to the housing while being permitted to rotate around their own axes.
