An axle assembly having an input shaft, an output shaft, and an interaxle differential unit. The interaxle differential unit includes a first side gear, a second side gear, a spider, at least one pinion gear, and a case. The case encircles the first side gear and the spider and has an integral drive gear.

Pass-through differentials are described.

A motor vehicle transmission system includes a reduction device having at least an output shaft including a first gearwheel and a second gearwheel. A differential drive device is configured to distribute the torque from the reduction device to two half-shafts. The differential drive device includes a coupling device which, in a coupled position, transmits torque between a first element and a second element of the differential drive device, the coupling device further including an actuator. A radial plane, orthogonal to the axes X and W, passes through the first gearwheel and through the coupling device.

The case encircles the first side gear and the spider and has an integral drive gear.

A transmission device includes a power-transmission case having a carrier of a reduction gear and a differential case joined to the carrier is supported in a transmission case via case support bearings, a specific planetary gear portion of a planetary gear is disposed on one side of a differential mechanism in an axial direction, and the specific case support bearing is disposed on the other side thereof An oil passage-forming body is provided on an inner wall of the transmission case, the oil passage-forming body comprising an oil collection part that opens upward and can collect lubricating oil splashed up in an area around the specific planetary gear portion within the transmission case accompanying rotation of the power-transmission case, and an oil reservoir part that is continuous from the oil collection part, stores lubricating oil collected by the oil collection part, and supplies the lubricating oil to the specific case support bearing.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

An input arrangement for a drive axle system and a drive axle system are provided. The input arrangement comprises a splined sleeve and an input shaft. The splined sleeve has a first end drivingly engaged with a portion of a driveshaft and a second end which defines a splined recess. The input shaft has a first splined portion on an end of the input shaft. The first splined portion is complimentary to and axially slidably engageable with the splined recess of the splined sleeve. The input arrangement for a drive axle drive system eliminates a need for a companion flange, reduces a weight of the drive axle system, and reduces noise, vibration and harshness.

A differential assembly arrangement with optimized pinion shaft bearing lubrication is provided. The assembly includes a housing, a ring gear, a pinion gear, a pinion shaft supported by two rolling element bearings, a sleeve, and a lubrication deflector. The two rolling element bearings, a pinion head bearing bearing and a pinion tail bearing, are located at each end of the sleeve which fits over the pinion shaft. The sleeve helps facilitate the application of a pre-load to the bearings. The lubrication deflector is located along the length of the sleeve for providing the correct amount of lubricant to the two bearings. The deflector is in the form of a ring located on the sleeve or integrated within the sleeve.
