Abstract

The invention relates to a selective freewheeling mechanism for developing an electromechanical vehicle brake (service brake) into a parking brake. The freewheeling mechanism according to the invention has an outer ring and a locking element cage which are configured as an electric motor with a rotor and a stator. The rotor and stator can be swiveled in relation to each other when a coil is supplied with current. Due to a symmetric design, the freewheeling mechanism is advantageously insensitive to acceleration forces.
