Abstract
A self-energizing disk brake is described. The brake includes an electric actuator in which an activation force is amplified using a self-energizing device arranged between the electric actuator and a brake lining. The system includes a brake application unit for applying the brake lining to a brake disk with an application movement of the brake lining, relative to the brake disk, having a component extending parallel to a rotational axis of the brake disk and another component extending tangentially to the rotational axis of the brake disk. At least one electromotive drive for activating the brake application unit and at least two brake plungers of the brake application unit are provided. Pressure surfaces of the brake plungers have a recess with a ramp shaped contour for engagingly receiving a rolling element.
