Abstract:
A mechanism for changing the operating condition of a shifting element having two shifting element halves, which can either be functionally connected to connect two components or disengaged to break the connection between the components. The mechanism includes a drive machine and a drive converter unit in the area of which rotary drive motion of the drive machine can be converted into a translational actuation movement of the shifting element. A spring device is associated with the drive converter unit, whose spring force assists with actuating the shifting element in the engaging direction. The spring device includes an approximately circular flat spring element which, in at least one area of the drive converter unit, is in contact with at least one cam, whose stress condition varies as a function of an operating condition of the drive converter unit and is designed to be rotationally fixed.
