  • Torsional vibration damper
    Patent number: 7484607
    Abstract: A torsional vibration damper in a gearbox housing has an input part connected to a drive and acts on a first damping unit and an intermediate part which acts as the output of the first damping unit and as the input of a second damping unit. The torsional vibration damper further has an output part which is in working connection with the second damping unit and which is designed to accept a takeoff. Takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet. A sealing wall separates the torque-transmitting space from a damping space including the first damping unit.

  • Torsional vibration damper
    Publication number: 20060196751
    Abstract: A torsional vibration damper in a gearbox housing, equipped with an input part, which is connected to a drive and acts on a first damping unit; and an intermediate part. The intermediate part, in its first capacity, acts as the output of the first damping unit and has drive-side drive elements to interact with the first damping unit, and in its second capacity, acts as the input of a second damping unit and has takeoff-side drive elements to interact with the second damping unit. The torsional vibration damper further has an output part, which is in working connection with the second damping unit and which is designed to accept a takeoff. The takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet.
