Abstract
A combined vehicle brake including a hydraulically actuated service brake and an electromechanically actuated parking brake device, a hydraulic operating pressure chamber in a brake housing being defined by a brake piston, which for performing service braking actions can be acted upon by hydraulic pressure fluid, so that the brake piston can be actuated along a piston longitudinal axis in order to produce a braking action, and the parking brake device acting on the brake piston by way of a transmission that translates the rotary motion of an electromechanical actuator into a translational motion and actuates the brake piston to perform parking brake actions and to keep it in the actuated position. Also disclosed is a transmission for translating a rotary motion into a translational motion by way of a screw spindle and a spindle nut, which are in contact with one another by way of multiple rolling elements.
