The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.
Claims20
An axle assembly comprising:
- an electric motor module having a rotor that is rotatable about a first axis;
- a drive pinion that extends through the rotor and is rotatable about the first axis;
- a rotor bearing assembly that rotatably supports the rotor on the drive pinion, wherein the rotor bearing assembly extends from the drive pinion to the rotor;
- a gear reduction module that has:
- a set of drive pinion gears that includes a first gear that is operatively connected to the rotor and a second gear;
- and
- a first countershaft subassembly that includes a first countershaft that is rotatable about a first countershaft axis, a first countershaft gear is that is disposed on the first countershaft and that meshes with the first gear, and a second countershaft gear that is disposed on the first countershaft and that meshes with the second gear;
- and
- a first drive pinion bearing and a second drive pinion bearing that rotatably support the drive pinion, wherein the rotor and the set of drive pinion gears are axially positioned between the first drive pinion bearing and the second drive pinion bearing.
