Abstract
An actuator assembly (12), in particular for an electromechanical vehicle brake (10), is specified, having a brake caliper (14) in which an intermediate space (16) is present for receiving a brake rotor (18), a ball screw drive which has an actuating slide (24) for applying a brake pad (20) onto the brake rotor (18) and an electromotively driven spindle (26) for the axial movement of the actuating slide (24), wherein the actuating slide (24) can be moved by axial displacement between an extended position and a retracted position. The spindle (26) has a spindle shaft (28) and an output sleeve (30) which is separate from the spindle shaft (28) and which is arranged in toothed and torque-transmitting engagement on the spindle shaft (28). A threaded raceway (32) is formed on the external peripheral surface of the output sleeve (30) and an opposing raceway (34) for balls is formed on the internal peripheral surface of the actuating slide (24).
