A drive system for an electric vehicle includes a housing having a first housing portion, a second housing portion connected to the first housing portion, and a third housing portion connected to the second housing portion. The third housing portion includes a torque arm connectable to a vehicle chassis. A hypoid gear set is mounted in the first housing portion, and an electric motor is mounted in the third housing portion.

Axle including a drive system for an electric vehicle

A motor vehicle drive-axle includes a drive-axle housing defining a gear-set cavity and a shaft bore having first and second bearing pockets and an oil cavity arranged between the first and second bearing pockets. The housing also defines a supply channel and a return passage configured to respectively supply oil from the gear-set cavity to the oil cavity and return oil from the oil cavity to the gear-set cavity. The housing also includes an input shaft extending through the shaft bore into the differential gear-set cavity. The housing additionally includes first and second bearings arranged within respective first and second bearing pockets for supporting the input shaft. The housing additionally includes a lubrication regulating insert arranged inside the oil cavity. The insert defines first and second lubrication channels configured to direct oil from the supply passage to respective first and second bearings.

Differential assembly oil management insert

An axle assembly includes an axle housing having a passage. An axle extends through the passage. A bearing supports the axle in the passage. An adaptive bearing preload adjustment system is mounted adjacent the bearing. The adaptive bearing preload adjustment system is selectively activatable to adaptively adjust a preload force on the bearing.
