ABSTRACT:
An electromechanical wheel brake device has a helical gear for converting the rotating motion of an electric motor into a translating motion of a brake piston in order to press a brake pad against a brake disc in an advancing stroke or in order to release the brake pad in a restoring stroke. In addition, a clutch is provided, which operatively disengages a part of the helical gear from the electric motor should a permissible restoring stroke be exceeded. This prevents a mechanical failure or damage to the wheel brake device in the event of such a malfunction. The electromechanical wheel brake device can be used in motor vehicles such as cars.
