Abstract

An axial adjusting device comprising 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. Of the discs, one is axially supported and one is axially displaceable against resilient returning forces of spring means. At least one of the discs is rotatingly drivable by a driving motor. For load reducing purposes, at least two balls are guided in each of the pairs of ball grooves.
