Abstract
An electric axle drive unit for a motor vehicle, having an electric motor with a stator that is fixedly received in a housing, and a rotor that is rotatably mounted relative to the stator and rotationally coupled or coupleable to a wheel hub. A brake device is operatively connected to the wheel hub. The brake device has a first brake component fixedly supported on the housing, a second brake component rotationally fixed to the wheel hub that is frictionally connectable to the first brake component, and an actuation unit that applies a braking force that interconnects the brake components. One of the brake components has a brake disc element rotationally fixed to a support part and is displaceably received in the axial direction of a rotational axis of the wheel hub relative to the support part.
