Operating device for an eletromechanically actuated disk brake

摘要

The present invention relates to an actuating unit for an electromechanically operable disc brake for automotive vehicles preferably comprising a driving unit (1) or an electric motor (11), an actuating element (7) secured against rotation and causing one (4) of two friction linings (4, 5) that are arranged slidably in a brake caliper to move into engagement with a brake disc (6), as well as a reducing gear (2) interposed between the electric motor (11) and the actuating element (7). To ensure the testability of the reducing gear, the present invention proposes that the means (27) for providing the anti-rotation mechanism of the actuating element (7 or 16, respectively) be arranged in a gearbox casing (24) accommodating the reducing gear (2).
