  • Patent number: 7604542
    Abstract: 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.

  • Publication number: 20090133529
    Abstract: A torsional vibration damper has a drive side transmission element connected to a drive; a takeoff side transmission element, which can be brought into working connection with a takeoff and which can rotate with respect to the drive side transmission element; and a damping device installed between the two transmission elements, the damping device being equipped with a spring system, which serves to transmit torque between the drive side and the takeoff side transmission element and has at least one reservoir space containing a gaseous medium. Each reservoir space of the spring system is in working connection with an assigned pressure space of a pressure circuit containing a fluid medium, where the pressure circuit can be used to adjust the pressure present in the pressure space when the torque to be transmitted by the spring system changes and thus to adapt the characteristic of the spring system to the new torque as needed.

  • Patent number: 7264100
    Abstract: A dual clutch assembly includes a torsional vibration damper and a dual clutch. The vibration damper has a primary side which can be coupled to a driving member for joint rotation about an axis, a secondary side which is rotatable about the axis, and a damper element arrangement between the primary side and the secondary side. The dual clutch includes an input area and two output areas, the input area supporting the secondary side of the torsional vibration damper in at least one of an axial and radial direction with respect to the primary side, each output area being coupleable with a respective driven member so as to be fixed against rotation with respect to the driven member. A bearing arrangement supports the input area in at least one of an axial and a radial direction with respect to a stationary subassembly.

  • Patent number: 6830139
    Abstract: 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—relative to an axis of rotation (A)—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.

  • Publication number: 20040118655
    Abstract: A torque transmission arrangement includes a torsional-vibration damper arrangement having a primary side for fixing to a drive member and a secondary side rotatable about an axis of rotation (A) with respect to the primary side counter to the action of a damper element arrangement. A double clutch arrangement is coupled to the secondary side of the torsional-vibration damper arrangement and has a first clutch region for selective torque transmission coupling to a first output member and a second clutch region for selective torque transmission coupling to a second output member. A selectively activatable rotary-state influencing arrangement can limit the rotational movement of the secondary side with respect to the primary side and/or to a subassembly essentially nonrotatable about the axis of rotation (A).
