  • 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: 6578687
    Abstract: 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.
