A threaded drive, in particular for an actuator, for example a hydraulic clutch actuator, in a motor vehicle, comprises a linearly displaceable spindle (6) and a spindle nut (4) which is stationary in the linear direction with respect to a housing (12) of the actuator and is connected fixedly to a rotor (3) of an electric motor so as to rotate with it, and at least one bearing (11), in particular a ball bearing, which is provided for mounting the rotor (3) in a manner which is fixed in the axial direction, and a pressure piece (10) which is connected to the spindle (6). On that side of the spindle (6) which faces away from the pressure piece (10), said spindle (6) is guided in a spindle guide (7, 8, 9) which comprises at least one attaching sleeve (8) and a guided sliding element (9), wherein the attaching sleeve (8) is arranged coaxially with respect to the spindle (6) and is fastened to the housing (12), and the guided sliding element (9) is configured at least indirectly for mounting the spindle (6) in the attaching sleeve (8) in a manner which is secured against rotation. |
