Abstract
An axle assembly having a differential carrier that includes a bearing support wall that at least partially defines a first lubricant chamber. A rotor output flange that is fixedly coupled to a rotor may at least partially defines a second lubricant chamber. At least one seal may separate the first lubricant chamber from the second lubricant chamber.
Claims20
An axle assembly comprising:
- a differential carrier having a bearing support wall that extends around an axis and at least partially defines a first lubricant chamber that receives a drive pinion bearing that rotatably supports a drive pinion;
- a rotor that is rotatably disposed on the bearing support wall and is disposed in an air chamber;
- a rotor output flange that is fixedly coupled to the rotor, wherein the rotor output flange at least partially defines a second lubricant chamber;
- a first seal that extends between the bearing support wall and the drive pinion and separates the first lubricant chamber from the second lubricant chamber;
- and
- a second seal that extends between the bearing support wall and the rotor output flange and separates the air chamber from the second lubricant chamber.

An axle assembly comprising:
- a differential carrier having a bearing support wall that extends around an axis and at least partially defines a first lubricant chamber that receives a drive pinion bearing that rotatably supports a drive pinion;
- a motor cover that is spaced apart from the differential carrier;
- a motor housing that extends from the differential carrier to the motor cover, wherein the motor housing receives a rotor that is rotatably disposed on the bearing support wall and is disposed in an air chamber that is located between the differential carrier and the motor cover;
- a rotor output flange that is fixedly coupled to the rotor, wherein the rotor output flange at least partially defines a second lubricant chamber;
- a seal carrier plate that is mounted to the motor cover;
- and
- an inner seal that extends between the seal carrier plate and the rotor output flange, wherein the inner seal separates the air chamber from the second lubricant chamber.
