Patent ID: 8136639

Claim:
A self-energizing disk brake having an electric actuator for applying an actuating force, comprising: a self-energizing device for boosting the electric actuator, arranged between the actuator and at least one brake lining; a brake application unit for applying the at least one brake lining to one side of a brake disk, while an application movement of the brake lining to the brake disk is carried out, the application movement being resolvable into at least one parallel movement component and at least one movement component extending one of tangentially and perpendicularly relative to a rotational axis of the brake disk; and at least one electric motor drive of the electric actuator for actuating the brake application unit to apply the actuating force, wherein the brake application unit moves the brake lining on an arched curved path, parallel to a friction face of the brake disk, the brake application unit having a crank which has a crank pin, the crank having a crank axis extending parallel to the rotational axis of the brake disk and serving to move the brake lining tangentially with respect to the brake disk, parallel to the friction face of the brake disk, and engages positively into a corresponding opening in a pressure plate of the brake lining.
