Axle Assembly Having an Electric Motor Module and a Gear Reduction Module

An axle assembly comprising:

• an axle housing;
• a differential carrier that is mounted to the axle housing and rotatably supports a differential;
• a differential carrier cover that is mounted to an end of the differential carrier that is disposed opposite the axle housing, the differential carrier cover having a gear cavity that is disposed outside of the differential carrier and opposite the differential carrier;
• an electric motor module that is completely disposed in the differential carrier;
• and
• a gear reduction module that is at least partially received in the gear cavity, wherein the gear reduction module transmits torque from the electric motor module to the differential via a drive pinion, wherein lubricant flows between the axle housing and the gear cavity by flowing through the differential carrier housing.
