  • Patent number: 10995818
    Abstract: A torque transmission device for a powertrain of a motor vehicle has an input area and an output area. A torque path runs from the input area to the output area. A torsional vibration damping unit is positioned first, followed by a gear unit, along the torque path between the input area and the output area. The torsional vibration damping unit provides a first spatial area and an adjoining second spatial area along the torque path, and the gear unit provides an adjoining third spatial area.

  • Patent number: 10738839
    Abstract: A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.

  • Patent number: 10704619
    Abstract: A method for the transmission and damping of a mean torque with a superposed alternating torque in an arrangement having an input and an output. The mean torque and superposed alternating torque are transmitted along a path from the input to the output. A slip arrangement is provided in the torque path between the input and the output for transmitting mean torque and superposed alternating torque and for generating a speed slip between an input speed and an output speed in the path. The slip arrangement provides a maximum of an external activation of the speed slip in the area of the maxima of at least one periodic oscillation component of the alternating component and provides a minimum of an external activation of the speed slip in the area of the minima of at least one periodic oscillation component of the alternating component.

  • Patent number: 9005037
    Abstract: A rotational vibration damper includes a primary side (32) and a secondary side (46) which is rotatable with respect to the primary side (32) around an axis of rotation (A) against the action of a damper element arrangement (28). At least one damper element unit (42) of the first group (70) and at least one damper element unit (42?) of the second group (70?) are pre-loaded, and the primary side (32) and the secondary side (46) are pre-loaded in a basic relative rotation position with respect to one another. Proceeding from the basic relative rotation position of the primary side (32) with respect to the secondary side (46), a pre-loading path (V, V?) of at least one pre-loaded damper element unit (42) is shorter than a maximum relative rotation path of the primary side (32) with respect to the secondary side (46).

  • Patent number: 7648009
    Abstract: A torsional vibration damper for a bridging clutch of a hydrodynamic clutch arrangement has a drive-side damping device, which can be brought into working connection with the housing of the clutch arrangement and is provided with a drive-side transmission element, which acts via a drive-side energy-storage group on an intermediate transmission element, and a takeoff-side damping device, which uses a takeoff-side group of energy-storage devices to establish a working connection between the intermediate transmission element and a takeoff-side transmission element, which is connected to a takeoff-side component of the hydrodynamic clutch arrangement. A predetermined stiffness ratio is obtained between the energy-storage devices of a first group and the energy-storage devices of a second group, and the energy-storage devices of the drive-side group have a stiffness different from that of the assigned energy-storage devices of the takeoff-side group.
