Abstract

An axial setting device comprising two plates (24, 29) which are relatively rotatable and coaxially supported relative to one another and between which balls are guided in pairs of ball grooves (34, 39) in the plates (24, 29), with the depth of said pairs of ball grooves (34, 39) being circumferentially variable; of the plates (24, 29), one is axially supported and one is axially displaceable against the elastic returning forces of spring means; at least one of the plates (24, 29) is drivable via a driveline by a driving motor (11). Within the driveline, between the driving motor (11) and the drivable plates (24, 29), there is inserted a switching coupling (83).
