Abstract

The invention relates to an actuating device for a motor vehicle brake, comprising the following components:

an actuating device, in particular in the form of a brake pedal,a pressure supply device (11), in particular a reciprocating pump or double-acting reciprocating pump, driven by an electric motor drive (M),a piston-cylinder unit (main cylinder) (10) that can be actuated by means of the actuating device, that is connected hydraulically with a hydraulic fluid reservoir (BFR) and that forms at least two pressure chambers that are connected with hydraulic brake circuits,a valve assembly (HCU) with valves for adjusting brake pressures in a wheel-specific manner and for disconnecting or connecting the wheel brakes from or to the pressure supply device (11) and the piston-cylinder unit (10),an electronic control unit (ECU),at least one sensor device, having at least one sensor or evaluation element (3, 4, 5, 24, 24a) and a sensor target (5a, 23, 23a), preferably based on an electromagnetic principle,for sensing a movement of a device component.
