摘要： A hydraulic vehicle brake (10) has a hydraulic chamber (16) which sealingly accommodates a brake piston (18) which can slide along an axis (A). The brake piston (18) acts upon a friction member and can be moved by means of hydraulic pressure which is supplied to the hydraulic chamber (16) into an actuating position in which it presses the friction member against a rotor (brake disk, brake drum, etc.). In order to be able to use the vehicle brake (10) besides its function as a hydraulic service brake also as a parking brake, a spindle/nut arrangement (24) is provided which is driven by an electric motor (42) and arranged coaxial to the axis (A) of the brake piston (18), the nut (30) of which arrangement (24) is secured against rotation, and by rotation of the spindle (26) as a function of the sense of rotation can either be moved into contact with the brake piston (18) or be moved away from the brake piston (18) translatorily along the axis (A). For realizing a compact and economical construction, the output shaft (46) of the electric motor (42) extends at a lateral distance parallel to axis (A) and exits the electric motor (42) at the side facing away from the brake piston (18). In addition, a reduction gear (44) with a reduction ratio in the order of 200:1 is connected between the electric motor (42) and the spindle (26), with the electric motor (42) and the reduction gear (44) being designed as a subassembly (40) which can be handled separately.
