A brake system for an electric wheel drive unit has a housing that can be attached securely to the vehicle frame. The housing has a flange region and a shaft-like wheel carrier region secured to the flange region. A first brake component is connected to the housing and includes a first support part attached directly on a radial outer side of the wheel carrier region and a first brake disc element rotationally fixed to the first support part. A second brake component is rotatably mounted relative to the housing and has a second support part and a second brake disc element rotationally fixed to the second support part. A hydraulic actuation device is provided with one or more pressure pistons arranged. A sliding element is provided for moveably coupling the pressure pistons with one of the brake disc elements.

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.

In human-powered vehicles, e.g., bicycles, etc., it is customary to use drum brakes, disc brakes or shoe brakes. Each of the braking systems has different advantages in terms of braking effect, system costs, ease of maintenance, etc. A brake unit with a modified structure for a vehicle is provided. For this purpose, a brake unitfor a vehicleis disclosed, having a housing, having a brake body device, wherein the brake body devicesupports a stationary brake partner of a brake apparatusfor the vehicle, wherein the housingand/or the brake body devicedefines a main axis H, having an actuator for moving the brake body device relative to the housingin order to generate a braking force, wherein the stationary brake partner is formed as a brake disc
