Abstract
An axle assembly having a rotor bearing preload module. The rotor bearing preload module may be disposed between a first and second rotor bearing assemblies. The rotor bearing preload module may include a biasing member that may bias the first rotor bearing assembly away from the second rotor bearing assembly.
Claims22
An axle assembly comprising:
- a differential carrier;
- a rotor that is rotatable about an axis with respect to the differential carrier;
- a first rotor bearing assembly and a second rotor bearing assembly that are disposed on the differential carrier and rotatably support the rotor;
- and
- a rotor bearing preload module that is disposed between the first rotor bearing assembly and the second rotor bearing assembly, wherein the rotor bearing preload module includes a biasing member that biases the first rotor bearing assembly away from the second rotor bearing assembly.

An axle assembly comprising:
- a differential carrier;
- a rotor that is rotatable about an axis with respect to the differential carrier;
- a first rotor bearing assembly and a second rotor bearing assembly that receive the differential carrier and rotatably support the rotor;
- and
- a rotor bearing preload module that is disposed between the first rotor bearing assembly and the second rotor bearing assembly, wherein the rotor bearing preload module includes:
- a first bearing preload ring that extends from the first rotor bearing assembly and is moveable in an axial direction;
- a second bearing preload ring that extends from the second rotor bearing assembly;
- and
- a biasing member that is disposed between the first bearing preload ring and the second bearing preload ring that biases the first rotor bearing assembly away from the second rotor bearing assembly.
