Abstract
A ball-screw drive for an actuator assembly of a vehicle brake is disclosed, comprising a rotatably mounted recirculating ball screw on which a screw nut which is closed on one side is mounted, at least one thread being formed on the circumferential surface of the recirculating ball screw, in which thread a plurality of balls are guided in such a way that a rotation of the recirculating ball screw brings about an axial displacement of the screw nut along an axis of rotation of the recirculating ball screw. A ball return system is integrated in the recirculating ball screw. Furthermore, an actuator assembly comprising a ball-screw drive and a method for producing a ball-screw drive are indicated.
