Abstract
An electric drive unit and a drive axle system having an electric drive unit. The drive axle system also includes a drive shaft and an axle assembly that that is remotely positioned from the electric drive unit. The drive shaft operatively connects the electric drive unit to the axle assembly.
Claims20
A drive axle system comprising:
- an electric drive unit that includes:
- an electric motor having a rotor that is rotatable about a rotor axis;
- a shaft that extends through the rotor and that is rotatable about the rotor axis;
- and
- a transmission that operatively connects the rotor and the shaft;
- an axle assembly that is remotely positioned from the electric drive unit, the axle assembly including an axle housing assembly that receives a differential assembly and a drive pinion that meshes with a ring gear of the differential assembly;
- and
- a drive shaft that operatively connects the shaft to the drive pinion, wherein the electric drive unit is received in an engine compartment of a vehicle and the axle assembly is disposed rearward of the engine compartment of the vehicle.

An electric drive unit comprising:
- an electric motor having a rotor that is rotatable about a rotor axis;
- a shaft that extends through the rotor and that is rotatable about the rotor axis;
- a transmission that operatively connects the rotor and the shaft;
- a housing assembly that receives the electric motor, the shaft, and the transmission, wherein the housing assembly includes a support housing that is encircled by the rotor and that includes a tubular portion that encircles the shaft and a mounting flange that extends from an end of the tubular portion in a direction that extends away from the rotor axis, wherein the rotor is rotatably disposed on the tubular portion and the tubular portion includes a first internal wall that extends toward the rotor axis and that defines a first opening that receives a bearing that receives and rotatably supports the shaft;
- and
- a coupling that is fixedly disposed on the shaft outside of the housing assembly.

An electric drive unit comprising:
- an electric motor having a rotor that is rotatable about a rotor axis;
- a shaft that extends through the rotor and that is rotatable about the rotor axis;
- a transmission that operatively connects the rotor and the shaft;
- a housing assembly that receives the electric motor, the shaft, and the transmission, wherein the housing assembly includes a motor housing, a support housing, and an end housing, the motor housing encircles the electric motor, and the support housing is encircled by the rotor, encircles the shaft, and is mounted to the motor housing and the end housing such that the support housing separates the motor housing from the end housing;
- and
- a coupling that is fixedly disposed on the shaft outside of the housing assembly.
