HYDRODYNAMIC COUPLING DEVICE, IN PARTICULAR A TORQUE CONVERTER

摘要

The invention relates to a hydrodynamic coupling arrangement, in particular a torque converter, comprising a housing arrangement (12) that is or can be filled with fluid, a pump impeller (20), a turbine wheel (28), a lock-up clutch (54), and a torsional vibration damping arrangement (42) having an input area (52) and an output area (82), wherein a first torque-transmission path (46) and parallel thereto a second torque-transmission path (48) and a coupling arrangement (50) for superposing the torques transmitted by means of the torque-transmission paths (46, 48) are provided between the input area (52) and the output area (82), wherein the torsional vibration damping arrangement (42) further comprises at least in the first torque-transmission path (46) a phase-shifting arrangement (56) for producing a phase shift of rotational irregularities transmitted by means of the first torque-transmission path (46) relative to rotational irregularities transmitted by means of the second torque-transmission path.
