Abstract
An axial adjusting device includes two discs which are rotatable relative to one another and coaxially supported relative to one another, between which two discs balls are guided in pairs of ball grooves. The depth of the pairs of ball grooves is variable across the circumference of the discs. One of the discs is axially supported and one is axially displaceable against resilient returning forces of a first spring mechanism. At least one of the discs can be driven by a motor via a gear drive. A second spring mechanism is provided which—during the return motion of the discs, after the balls have reached their end positions in the ball grooves, which end positions are determined by the greatest groove depth—permit the drivable disc to overshoot against the resilient returning forces of the second spring mechanism.
