Abstract
A ball screw drive for an actuator assembly of a vehicle brake is disclosed, having a rotatably mounted recirculating ball screw spindle, on which a spindle nut open on one side is mounted. At least one thread groove is formed on the circumferential surface of the recirculating ball screw spindle, and a corresponding thread groove is formed on the inner surface of the spindle nut. A multiplicity of balls is guided in the thread grooves in such a way that rotation of the recirculating ball screw spindle brings about axial movement of the spindle nut along a rotational axis of the recirculating ball screw spindle. The spindle nut is manufactured from rolling bearing steel or from C steel.
