Abstract: A first clutch area produces a first torque-transmitting connection between a drive element and a first driven element, and a second clutch area produces a second torque-transmitting connection between the drive element and a second driven element. A common engaging/disengaging mechanism actuates the first clutch area and the second clutch area to produce and to nullify the first and second torque-transmitting connections.

Abstract: In a clutch for a motor vehicle, an axially displaceable contact-pressure disk has a number of driver elements guided by a guide and further driver elements which are supported with spring elements in another guide. In the disengaged state of the clutch, the spring elements preload the contact-pressure disk into a central position, in which the guided driver element is remote from a stop. This prevents the driver element from digging into the stop and hence prevents sticking of the contact-pressure disk in the engaged state of the clutch.

Abstract: A pressure plate subassembly for a friction clutch includes a housing connectable to an abutment arrangement for joint rotation about an axis of rotation, a pressure plate arranged in the housing so that the pressure plate is rotatable together with the housing about the axis of rotation (A) and so that the pressure plate is displaceable relative to the housing in the direction of the axis of rotation, and a force accumulator for generating a pressure force, the force accumulator being supported on the housing and on the pressure plate. The force accumulator is arranged outside the housing.

Abstract: A torsional vibration damper is embodied with a drive-side transmission element and an output-side transmission element, one of which is connected to the gear element of a gear active between the two transmission elements. The gear element is placed into movement during relative movements of the two transmission elements. The gear element is effective as the drive for at least one mass associated with it. Upon a position change of the mass relative to the rotational center of the transmission elements, a change occurs in the moment of inertia caused by the mass. The gear element is connected to the mass by a gear device that transforms its movement and/or changes the translation.

Abstract: A vibration damping device for a drive system of a motor vehicle, includes a deflection mass arrangement arranged in a base body which is rotatable about an axis of rotation (A). The deflection mass arrangement includes at least one deflection mass and a deflection path associated with the at least one deflection mass and along which the deflection mass moves during rotation of the base body about the axis of rotation (A). The deflection path has a vertex area and deflection areas on both sides of the vertex area. The deflection areas have a decreasing distance from the axis of rotation (A) as they proceed from the vertex area toward their circumferential end areas. A positive rolling arrangement is arranged between the at least one deflection mass and the deflection path which generates a rolling movement of the at least one deflection mass during the movement of the at least one deflection mass along the associated deflection path and thereby prevents a sliding movement of the deflection mass.

Abstract: An intermediate disk for a motor vehicle clutch with friction surfaces on both sides includes two disk parts. On the sides of the disk parts remote of the friction surfaces, the disk parts have spacers which laterally define recesses between the disk parts. This arrangement of the intermediate disk provides a large heat-releasing surface even when the intermediate disk has small dimensions.

Abstract: A torsional vibration damper including a disk-shaped first damper part, a second damper part which is rotatable about an axis with respect to the first damper part, and a torsion spring arrangement with at least one torsion spring unit. The at least one torsion spring unit includes at least two springs which are arranged substantially following one another in the circumferential direction. Further, there is at least one intermediate ring element which is rotatable about the axis with respect to the first damper part and the second damper part and with at least one spring contact arm for the at least one torsion spring unit. The spring contact arm extends substantially radially with respect to the axis. The at least one intermediate ring element has a radial movement restraining component for protecting the at least two springs against a movement in the radial outward direction in their end regions facing the at least one spring contact arm.

Abstract: A pressure plate housing for a clutch of a motor vehicle includes a housing cover and a housing wall integrally produced from sheet metal. Sleeves are arranged in the housing wall that have recesses designed for receiving connecting elements. The pressure plate housing has particularly small radial dimensions and can be produced very cost-effectively.

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.
