Abstract

An electromechanical brake actuator (102, 202, 302, 402) for a brake has a cam disc (108, 108′, 108″, 208, 308, 408) and a brake plunger (114, 214, 314) for actuating a brake lever (358). The cam disc (108, 108′, 108″, 208, 308, 408) and the brake plunger (114, 214, 314) have contact surfaces in contact with one another for directly transmitting a drive torque. The contact surface of the cam disc (108, 108′, 108″, 208, 308, 408) extends at a distance r about the pivot point D, which is defined as a function r(φ) with a change rate r′(φ) and depends on the angular position φ of the cam disc (108, 108′, 108″, 208, 308, 408). The contact surface is configured to effect non-linear transmission between the drive torque of the cam disc (108, 108′, 108″, 208, 308, 408) and the force transmitted to the brake plunger (114, 214, 314).
