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: A double-armature solenoid valve may include an adjustable first armature and an adjustable second armature arranged axially opposite each other along a common adjustment axis, and a coil mechanism configured to provide a magnetic flux. The valve may also include a first restoring spring, a second restoring spring, an inlet opening arranged on an axial side of the first armature opposite the second armature, and an outlet opening arranged on an axial side of the second armature opposite the first armature. The inlet opening and the outlet opening may be connected via a fluid duct. The first armature and the second armature may respectively have a different closing time such that when an energization of the coil mechanism is at least one of interrupted and reduced the inlet opening is closable more quickly via the first armature than the outlet opening via the second armature.

Abstract: A device (1) for transmitting torque for driving an auxiliary unit, in particular an alternator, preferably in a motor vehicle, and for damping torsional vibrations, said device comprising driving means (2) that can be driven about an axis of rotation (4) by an internal combustion engine, and output drive means (3) rotatable about the axis of rotation (4) that are arranged and designed for driving the auxiliary unit, wherein at least one axial front face of the driving means (2) and/or of the output drive means (3) carries permanent magnet means (10, 11) which allow torques to be transmitted between the driving means (2) and the output drive means (3) and which allow torsional vibrations to be dampened, the poles (13, 14, 15, 16) of the permanent magnet means (10, 11) being arranged in at least one radial plane, characterized in that the permanent magnet means (10, 11) comprise a plurality of permanent magnet elements (17) arranged next to each other in the circumferential direction, these permanent magnets (
