Abstract
An axle assembly that includes an axle housing, a differential carrier, and an electric motor module. The differential carrier that is mounted to the axle housing and rotatably supports a differential. The electric motor module is received inside the differential carrier and is operatively connected to and provides torque to the differential.
Claims20
An axle assembly comprising:
- an axle housing;
- a differential carrier that is mounted to the axle housing and rotatably supports a differential, wherein the differential is at least partially received in the axle housing;
- and
- an electric motor module that is received inside the differential carrier, wherein the electric motor module is operatively connected to the differential and provides torque to the differential.

An axle assembly comprising:
- an axle housing;
- a differential carrier that is mounted to the axle housing and rotatably supports a differential, wherein the differential carrier includes:
- a bearing support wall that extends around an axis and defines a hole;
- and
- an exterior wall that is spaced apart from the bearing support wall, wherein the exterior wall extends around the bearing support wall such that the exterior wall and the bearing support wall cooperate to at least partially define an outer cavity that extends around the axis;
- and
- a differential carrier cover disposed on an end of the exterior wall that is disposed opposite the axle housing;
- an electric motor module that is received inside the outer cavity and has a rotor that is rotatable about the axis;
- a drive pinion that is rotatable about the axis and extends through the hole, wherein the drive pinion is operatively connected to the rotor between an end of the bearing support wall and the differential carrier cover and the electric motor module provides torque to the differential via the drive pinion.
