Abstract

A motor vehicle includes a drive motor, a torque transfer device with an actuating device, a gearbox with at least one shift shaft, an actuating device, and a control device. The actuation of the torque transfer device and the gearbox is automatically controlled through the control device or an input thereto. The gearbox actuation includes a first and second movement component, e.g., a rotational and translation movement. The gearbox actuating device has a first and second drive dedicated to the first and second movement components. A multi part element transfers movement to the shift shaft and includes at least one axial groove for the axial guidance and rotational movement transfer, and at least one ring groove or ring groove segment for the rotational guidance and axial movement transfer. The multi part element includes at least one sleeve like element having a toothed spline, a follower, and a toothed rod.
