摘要： A combined vehicle brake having a hydraulically actuable driving brake and an electromechanically actuable parking brake device. In a brake housing, a hydraulic operating pressure space is bounded by a brake piston chargeable with hydraulic pressure medium to carry out normal braking. The brake piston is actuable along a longitudinal axis of the piston, and the parking brake device acts on the brake piston by a gearing converting the rotational movement of an electromechanical actuator into a translation movement and bringing about an actuation of the brake piston in order to carry out parking brake operations and keeping the brake piston in the actuated position. The gearing has a threaded spindle and a threaded nut which are in contact with each other via a plurality of rolling bodies. The frictional moment transmitted by the further axial bearing is higher than the returning torque of the threaded spindle.
