Patent ID: 8875851

Claim:
An electromechanical vehicle brake comprising: a hydraulic operating pressure chamber that is delimited in a brake housing by a brake piston which is configured to be loaded by hydraulic pressure medium in order to perform service braking operations, such that the brake piston is configured to be actuated hydraulically along a longitudinal piston axis (A) in order to produce a braking effect, and an electromechanical actuator which acts on the brake piston by a gear unit, wherein the gear unit converts rotary motion of the electromechanical actuator into a translational motion, causing the brake piston to be actuated to perform parking brake processes and to remain in the actuated position, wherein the gear unit comprises a threaded spindle and a threaded nut which contact one another via a plurality of rolling elements, a spring element that allows the rolling elements to slip when the gear unit is actuated in an unloaded state while causing the rolling elements to roll when the gear unit is actuated under load, wherein the spring element is arranged between the rolling elements and a pocket-shaped recess which is formed in the threaded nut and forms a stop for the spring element, one end of the spring element directly abutting against a stop face of the pocket-shaped recess defined by the threaded nut.
