TORSIONAL VIBRATION DAMPING ARRANGEMENT FOR THE POWERTRAIN OF A VEHICLE

摘要

A torsional vibration damping arrangement (10) for the drivetrain of a vehicle comprises an input region (50) to be driven in rotation around an axis of rotation A and an output region (55), and a first torque transmission path (47) and parallel thereto a second torque transmission path (48) which proceed from the input region, and a coupling arrangement (41) for superposing the torques guided via the two torque transmission paths, which coupling arrangement (41) communicates with the output region, and a phase shifter arrangement (43) for the first torque transmission path for generating a phase shift of rotational irregularities guided via the first torque transmission path relative to rotational irregularities guided via the second torque transmission path. The phase shifter arrangement comprises at least one spring set (40) with a curved spring (90).
