SELF-ENERGIZING DISK BRAKE

摘要

Disclosed is a self-energizing disk brake which comprises an electric actuator and in which an actuating force that is applied by the actuator is boosted with the aid of a self-energizing device located between the actuator and the brake lining. The inventive disk brake comprises the following features: - a clamping unit for clamping at least one brake lining (20) on one side of a brake disk (2) by performing a clamping movement of the brake lining (20) towards the brake disk (2), said clamping movement being divided into at least one movement component extending parallel to the axis of rotation (BA) of the brake disk and at least one movement component (U direction) extending tangential or perpendicular to the axis of rotation (BA) of the brake disk; - at least one electromotive drive unit (23) as an actuator for actuating the clamping unit; - the clamping unit is designed so as to move the brake lining or the brake lining unit (20) on a non-linear path, especially a curved trajectory, parallel to the frictional surface of the brake disk; and - the clamping unit is provided with a crank (34) that encompasses a crank pin (35) which extends parallel to the axis (BA) of the brake disk, is used for moving the brake lining unit tangential to the brake disk, i.e. parallel to the frictional surface of the brake disk, and positively engages into a corresponding hole in the pressure plate (18) such that the brake lining unit directly follows the movement of the crank.
