Actuating device for a clutch and the drive rod assembly with a coupling and an actuating device

摘要

The present invention relates to an actuating device for a coupling with a stator device, which is arranged in a rotationally fixed manner with respect to a supporting structural member, a with respect to the stator device and a rotor device, which can be rotated with respect to the rotor device in the axial direction is limited moveable slide means, wherein between the rotor device and of the slide means with a rolling-body at least three windings, and a circumferential groove is provided with rolling elements rolling elements, while the roller bodies channel formed in such a way, a track change region, that the rolling elements in the circumferential direction in front of the lane change range between a first and a second turn run, and roller bodies in the circumferential direction according to the lane change region between the second and a third winding run, at least one energy store between the slide means and the supporting structural member is provided, as well as a drive rod assembly, in particular for a motor vehicle with a coupling and of a corresponding actuating device.
