Hydrodynamic clutch device

摘要

A wet clutch arrangement includes a housing arrangement which is filled or fillable with fluid, a first friction surface formation which is rotatable with the housing arrangement around an axis of rotation and a second friction surface formation which is rotatable with a driven member around the axis of rotation and which can be brought into frictional engagement with the first friction surface formation by a piston pump. At least a portion of a torsional vibration damping arrangement is provided in a torque transmission path and includes an input region and an output region. The torsional vibration damping arrangement further includes at least in a first torque transmission path a phase shifter arrangement for generating a phase shift of rotational irregularities transmitted via the first torque transmission path relative to rotational irregularities transmitted via a second torque transmission path.
