1. A friction surface clutch (10, 41) for use in motor vehicles, wherein the friction surface clutch comprises a first tapered element (11, 31, 42) having a first friction surface (12) and a second tapered element (13, 43) 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, and
wherein the actuating device comprises a pressure element (21, 32, 46) 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 (30, 35, 45), 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 in order to disconnect the force-locked connection, wherein the pressure element can be detached from the guide part when the wear limit of the friction surfaces is reached such that the pressure element can no longer engage with the lever device after leaving the guide part, so that the force-locked connection can no longer be disconnected.
