摘要： A combined electromechanical vehicle brake has a hydraulically activated operating brake and an electromechanically activated parking brake apparatus. A hydraulic operating pressure chamber in a brake housing is delimited by a brake piston that can be loaded by hydraulic pressure to carry out operating braking actions. The brake piston can be activated along a longitudinal piston axis to achieve a braking effect. The parking brake apparatus acts upon the brake piston by a gear unit because the gear unit converts the rotational movement of an electromechanical actuator into a translational movement, causing the brake piston to be activated to carry out parking brake processes and remain in the activated position. The gear unit has a threaded spindle and a threaded nut that contact one another via a plurality of rolling elements. A spring element allows the rolling elements to slip when the gear unit is activated in the unloaded state.
