A torsional vibration damper includes a drive-side transmission element connected to a drive and a takeoff-side transmission element, which can deflect rotationally with respect to the drive-side element. A damping device is installed between the two transmission elements and transmits torque between the drive-side transmission element and the takeoff-side transmission element. The damping device has a gas spring system with a reservoir containing a gaseous medium. The reservoir of the gas spring system is connected to a pressure circuit which allows, at least when there is a change in the torque to be transmitted by the gas spring system, adjustment of pressure in the reservoir to adapt the characteristic of the gas spring system to a new torque.

Torsional vibration damper

A multi-clutch arrangement, especially a dual clutch for motor vehicles, comprising a first clutch area with a first pressure plate arrangement, with a first opposing support arrangement, and with a first clutch disk arrangement, which can be clamped between the first pressure plate arrangement and the first opposing support arrangement to transmit torque via the first clutch area; and a second clutch area with a second pressure plate arrangement, with a second opposing support arrangement, and with a second clutch disk arrangement, which can be clamped between the second pressure plate arrangement and the second opposing support arrangement to transmit torque via the second clutch area. A torsional vibration damper arrangement is assigned to at least one of the clutch areas, and where&mdash;relative to an axis of rotation (A)&mdash;the torsional vibration damper arrangement is arranged at least partially in the axial area of the first clutch area and/or of the second clutch area.

Multi-clutch arrangement

A torsion damping mechanism with a torsion damper with an input side and an output side, where the input side and the output side are connected elastically to each other by spring-type stored energy elements for rotation in common auxiliary mass which can rotate coaxially to the torsion damping mechanism is connected frictionally to the torsion damping mechanism by way of a friction area, where the frictional connection between the torsion damping mechanism and the auxiliary mass has a predetermined frictional moment. When this moment is exceeded during the occurrence of peaks in the torque being applied to the torsion damping mechanism, the auxiliary mass can slip or slips.

Torsion damping mechanism with auxiliary mass

A leaf spring arrangement, especially for connecting a pressure plate to a housing, comprises a plurality of adjacent leaf spring elements, where each leaf spring element has a first attachment area for establishing the connection the pressure plate, a second attachment area for establishing the connection to the housing, and a connecting area extending between the first attachment area and the second attachment area. At least certain areas of at least two of the leaf spring elements are spaced apart between their first attachment area and their second attachment area.

Leaf spring arrangement, especially for attaching the pressure plate of a pressure plate assembly to a housing

A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.

Pressure plate assembly for a friction clutch

A torsion damping mechanism with a torsion damper with an input side and an output side, which are connected elastically to each other by spring-type stored-energy elements, and with an auxiliary mass which can rotate coaxially to the torsion damper. A combination bearing has a first bearing section for supporting the input side and the output side against each other, and a second bearing section for supporting the auxiliary mass.
