Abstract

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.
