Abstract: An actuator with a planetary screw drive (PSD), in particular to operate a clutch of a vehicle, wherein a centric spindle having a pitch is connected non-rotatingly to a rotor of a drive and is drivable by the drive around an axis of rotation, and a plurality of planetary rollers are engaged with the spindle and mesh with a ring gear encircling the planetary rollers which has grooves in the circumferential direction, wherein both ends of the planetary rollers are positioned in a planetary roller carrier. The planetary roller carriers are supported non-rotatingly on both ends in such a way that a fixed assignment of the pitch of the spindle to an axial travel of a component that is movable axially by the PSD, which is operatively connected to an axially actuatable piston, is realized.

Abstract: A spindle drive unit, in particular for an actuator having a planetary screw drive (PWG) for actuating a clutch of a motor vehicle by an actuating element is provided, where the drive unit has an e-motor with a rotor and a stator and where a spindle provided with a pitch is connected non-rotatingly to the rotor and is drivable by the rotor around an axis of rotation. The spindle is designed as a threaded rod and a rotor carrier that holds the rotor is screwed onto the threaded rod, and the rotor carrier is rotationally secured and axially fixed on the spindle by a lock nut.

Abstract: An actuating device for the selection and/or actuation of a gear ratio of a motor vehicle transmission and for engaging and/or disengaging a motor vehicle clutch, having a drive motor which drives a drive shaft that is connectible non-rotatingly to a gear selector drum of a transmission actuating device to move and/or rotate the gear selector drum, the gear selector drum also being connected to a transmission, and having a clutch actuating device which controls a release bearing of a clutch, wherein a master cylinder of the clutch actuating device, which is connected hydraulically to a slave cylinder that moves the release bearing, is actuatable depending on the position of the drive shaft, wherein an actuating segment which protrudes in the radial direction from the drive shaft is connected non-rotatingly to the drive shaft and the actuating segment actuates the master cylinder when the drive shaft is rotated in at least one direction of rotation, as well as to a drivetrain having such an actuating device is
