Abstract

A hydraulic vehicle brake with a parking brake device, in particular for motor vehicles, includes a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, wherein hydraulic pressure fluid can be applied to the hydraulic service pressure chamber for carrying out service brake operations so that the brake piston is actuatable along a longitudinal piston axis in order to achieve a braking effect. The parking brake device acts on the brake piston with an actuating device, which actuates a rolling-element ramp-type gear with an electromechanical actuator.In order to achieve a higher rate of overall efficiency as well as a reduced electric energy consumption, a two-step gear is interposed between the electromechanical actuator (7) and the actuating device (4), wherein the first gear step (11, 21, 31) on the inlet side is connected to an output shaft (8) of the electromechanical actuator (7) and the second gear step (12, 22, 32) on the outlet side is connected to the rolling-element ramp-type gear (1, 2, 3).
