A friction surface clutch () 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.

The proposal is for a switchable friction clutch having a drive wheel () driven by a drive motor via a drive belt, wherein a first electromagnet arrangement () is provided for actuating a first friction clutch (), and a second electromagnet arrangement () is provided for actuating a second friction clutch () in order to be able to drive a drive shaft () of an auxiliary unit () at different rotational speeds via the drive wheel () at one rotational speed of the drive wheel. According to the invention, a belt drive arrangement is provided between the drive wheel () and the drive shaft () of the auxiliary unit () to drive the drive shaft () at the different speed.

An electromagnetic friction clutch () is proposed having two clutch plates () which have concentrically circular, magnetically soft ring areas (--) which are at least partially magnetically insulated from one another, which friction clutch () transmits comparatively large torques while having a compact design. For this purpose, pole faces (--) which, when viewed in the radial cross section, oscillate in the axial direction are formed at the magnetically soft ring areas (--).

The invention relates to a shiftable friction clutch () for actuation with a pressure medium. Clutches of this type can be used, for example, to drive auxiliary assemblies such as fans () in vehicle construction. An especially compact construction is achieved through the use of a disk spring (). A production method is furthermore proposed.
