Abstract: A clutch disk includes a hub area and a plurality of friction lining elements arranged in sequence in the circumferential direction relative to a clutch disk rotational axis, each providing at least part of an associated friction surface area. The friction lining elements are intended to make frictional contact with the associated opposing friction surface of a flywheel, a pressure plate, or the like. At least one of the friction lining elements is supported on the hub area in such a way that it can move in the radial direction.

Abstract: A double clutch assembly comprising a first clutch area for the optional production of a torque-transmitting connection between a drive element and a first driven element, a second clutch area for the optional production of a torque-transmitting connection between the drive element and a second driven element, and a common engaging/disengaging mechanism, by means of which the first clutch area and the second clutch area can be actuated to produce or to nullify the torque-transmitting condition.

Abstract: A multi-plate clutch for a motor vehicle has a U-shaped spring element fastened to an intermediate plate for holding adjacent pressure plates at a distance from one another. The intermediate plate is reliably held between the pressure plates. Grinding of friction facings arranged between the intermediate plate and the pressure plates is accordingly minimized. The spring element is arranged in an area of an external toothing of the intermediate plate and therefore does not contribute to an increase in the radial dimensions of the multi-plate clutch.

Abstract: A pressure plate for a friction clutch has a friction-surface region which can be pressed against a friction-lining arrangement of a clutch disk or the like. The pressure plate, in the friction-surface region, is formed at least partially from a first material which provides rapid dissipation of heat generated by friction, and in a body region which adjoins the friction-surface region, is formed from a second material which has a high heat absorption capacity for the heat dissipated from the friction-surface region.

The wrap spring arrangement is at connective rest with a first spring section on a circumferential surface of the first component for torque transmission and is at connective rest with a second spring section on the circumferential surface of the other component.

Abstract: A torsional vibration damper has a drive-side transmission element and an output-side transmission element rotatable relative thereto. The output-side transmission element is centered relative to the drive-side transmission element via a radial slide bearing and can be held at a predeterminable axial distance from the drive-side transmission element by means of an axial slide bearing. The axial slide bearing has an inner circumference larger than the outer circumference of the radial slide bearing and rests, on the one hand, on at least one component of the first transmission element acting on the outer circumference of the radial slide bearing and, on the other, on at least one component of the other transmission element arranged on the inner circumference of the radial slide bearing, so as to form, together with these components, a covering for the radial slide bearing, by which the latter can be protected against an unwanted afflux of solid particles.

Abstract: A torsional vibration damper having an input part, an output part, and a plurality of coupling members coupling the input part with the output part. The input part and the output part are tiltable relative to one another so that when a wobbling movement of at least one of the parts occurs, this wobbling movement is not compulsorily or positively transmitted to the other part.

Abstract: A torsional vibration damper having a first damper element and a second damper element, which are connected to each other for the purpose of torque transmission by a first damping spring device. The first damping spring device has at least one damping spring arrangement with at least one damping spring. One of the damper element has a support on which the damping spring arrangement is supported in its respective end areas in approximately the circumferential direction via support elements. Further, a displacement surface is embodied on the first damper element for each support element. On the other damper element, there are carriers for each support element. Upon a relative rotation between the first and second damper elements, the carrier serve to take along the respective support elements and press them in the direction of the displacement surface for the purpose of movement along the associated displacement surface.

Abstract: A torsional vibration damper is equipped with a drive-side transmission element and an output-side transmission element deflectable relative thereto. A friction device is connected between the transmission elements. The friction device has a friction element with at least two different friction areas. The friction element is arranged in a circumferential opening having circumferential ends in one of the transmission elements. As long as the friction element is movable within the circumferential opening relative to the ends of the circumferential opening, only a first friction area of the friction element is active. When the friction element contacts one of the circumferential ends of the circumferential opening, only a second friction area of the friction element is active.

The clearance sensor has an operation lever segment that cooperates with a wear adjustment device, and an axial stop segment which cooperates with the flywheel. The pressure plate subassembly comprises the displacement contrivances, which displacement contrivances prevent a displacement of the clearance sensor, of which there is at least one, with respect to the pressure plate prior to the assembly of the pressure plate subassembly to the flywheel.
