Abstract: A friction surface clutch (10) for use in motor vehicles is provided. The friction surface clutch includes a first tapered element having a first friction surface and a second tapered element having a second friction surface, along with an actuating device having an actuating element for force-locked connection and disconnection of the tapered elements. The actuating device includes a pressure element coupled to the actuating element and a lever device interacting with the first tapered element. The first tapered element has a guide part in which the pressure element can be guided in a torsion-resistant way relative to the first tapered element prior to reaching a wear limit of the friction surfaces and can be engaged with the lever device to disconnect the force-locked connection. The pressure element can be detached from the guide part when the wear limit of the friction surfaces is reached.

Abstract: The invention relates to a friction surface clutch (10) for use in motor vehicles, in particular for switching an air compressor or the like, wherein the friction surface clutch comprises a first tapered element (11) having a first friction surface (12) and a second tapered element (13) having a second friction surface (14), wherein the friction surface clutch has an actuating device (15) having an actuating element (16) for force-locked connection and disconnection of the tapered elements, wherein the tapered elements are in force-locked connection in an unactuated operating state of the friction surface clutch, wherein the actuating device comprises a pressure element (21) coupled to the actuating element and a lever device (22) interacting with the first tapered element, wherein the pressure element can be engaged with the lever device in an actuated operating state of the friction surface clutch so that the force-locked connection can be disconnected, wherein the first tapered element has a guide part, in
