    摘要： A power transmission device is disposed between an engine and a transmission so as to be capable of attenuating fluctuations in torque. The device includes an input rotary part, an output rotary part, an elastic part, an inertia mass part and an engaging part. The torque is inputted to the input rotary part. The output rotary part is rotatable relatively to the input rotary part. The elastic part elastically couples the input rotary part and the output rotary part in a rotational direction. The inertia mass part is movable in the rotational direction. The engaging part is engaged with the elastic part and the inertia mass part. The engaging part actuates the elastic part by relative rotation between the input rotary part and the output rotary part and movement of the inertia mass part.

    摘要： 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).

    摘要： A damper assembly for a torque converter includes a drive side elastic element arranged for transmitting torque to a turbine for the torque converter in a first direction and a coast side elastic element, separate from the drive side elastic element, arranged for transmitting torque to the turbine in a second direction opposite the first direction. In an example embodiment, a slope of a torque curve for the damper remains constant in a transition region between transmitting torque to the turbine in the first direction and transmitting torque to the turbine in the second direction. In an example embodiment, the damper assembly includes an input damper and an output damper. The elastic elements are disposed in a torque path between the input damper and the output damper. In an example embodiment, the input damper is selectively engaged with a cover for the torque converter and the output damper is drivingly engaged with an output hub for the torque converter.

    摘要： A damper mechanism 6 is provided to transmit torque while absorbing and damping torsional vibrations. A small coil spring 45 achieves characteristics of a low rigidity in a small torsion angle region of the torsion characteristics when compressed by rotary members. A coil spring 33 achieves characteristics of a high rigidity in a large torsion angle region of the torsion characteristics when compressed by the rotary members rotating relatively to each other. A frictional resistance generating mechanism 7 generates a frictional resistance while each spring is being compressed. Owing to a rotating-direction space 79, the frictional resistance generating mechanism 7 does not operate in the second stage of the torsion characteristics and also does not in the first stage while a torsion angle is in a predetermined range.

    摘要： A torsional vibration damper includes two structural units rotatable relative to one another and linked to each other by a spring arrangement which includes at least one thrust piston. At certain angles of rotation between both structural units, the flow of force between the thrust piston of the spring arrangement and at least the secondary structural unit is realized via an outer surface area that engages the thrust piston, wherein the outer surface area is formed on a separate third structural unit which is resiliently mounted relative to the secondary structural unit.
