Abstract
An axle assembly having at least one lubricant passage. A differential carrier, a motor housing, and a cover may cooperate to at least partially define a first lubricant passage that routes lubricant from an axle housing to the cover. The differential carrier, motor housing, and cover may cooperate to at least partially define a second lubricant passage that routes lubricant from the cover to the axle housing.
Claims20
An axle assembly comprising:
- an axle housing that receives a differential assembly and that at least partially defines a sump portion that receives lubricant;
- a differential carrier that is mounted to the axle housing and supports the differential assembly;
- an electric motor module that includes:
- a motor housing that is mounted to the differential carrier, wherein the motor housing receives a stator and receives a rotor that is rotatable about an axis;
- and
- a cover that is mounted to the motor housing opposite the differential carrier, wherein the differential carrier, the motor housing, and the cover cooperate to at least partially define a first lubricant passage that receives lubricant from the axle housing and routes lubricant to the cover, wherein a portion of the first lubricant passage that is defined by the motor housing is radially positioned further from the axis than the stator.
