Patent ID: 8220593

Claim:
A self-energizing disc brake having an electric actuator in which an activation force applied to the actuator is amplified using a self-energizing device arranged between the actuator and a brake lining, comprising: a brake application unit for applying the brake lining to one side of a brake disc by carrying out an application movement of the brake lining relative to the brake disc, the application movement having at least a first movement component in a direction parallel to a rotational axis of the brake disc and a second movement component in a direction tangential to the rotational axis of the brake disc; at least one electromotive drive for activating the brake application unit; an electric motor of the at least one electromotive drive rotating via one of a direct drive and at least one gear mechanism; and a crank of the at least one electromotive drive, the crank having a crank tappet extending parallel to the rotational axis of the brake disc and engaging a correspondingly oriented opening in a pressure plate, wherein rotation of the crank tappet about a longitudinal axis of the crank tappet moves the pressure plate the direction tangential to the rotational axis of the brake disc.
