Abstract
A hydrodynamic coupling arrangement, particularly torque converter, comprises a housing arrangement () which is filled or fillable with fluid, an impeller (), a turbine (), a lockup clutch (), a torsional vibration damping arrangement () with an input region () and an output region (), wherein a first torque transmission path () and parallel thereto a second torque transmission path () and a coupling arrangement () for superposing the torques transmitted via the torque transmission paths () are provided between the input region () and the output region (), wherein the torsional vibration damping arrangement () further includes at least in the 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 the second torque transmission path.
