Abstract
An axial setting device having two discs () which are rotatable relative to one another, which are supported coaxially relative to one another and between which there are guided balls () in pairs of ball grooves () whose depth varies across the circumference. One of the discs () is axially supported and one is axially displaceable against elastic returning forces of first spring (). At least one of the discs can be driven by a motor () via a gear drive. During the return movement of the discs () after the balls () have reached their end position in the ball grooves, which end position is defined by the greatest groove depth, a second spring permits overshooting of the drivable disc () together with the disc () supported with respect to rotation against elastic returning forces of the second spring.
