Abstract:
1. A hydrodynamic coupling arrangement, comprising: a housing arrangement capable of being filled with a fluid; an impeller rotatable with the housing arrangement around an axis of rotation; a turbine arranged in the housing arrangement rotatable with a driven member around the axis of rotation; a lockup clutch for producing a torque transmission connection between the housing arrangement and the driven member; a torsional vibration damping arrangement including an input region and an output region; a first torque transmission path; a second torque transmission path parallel to the first torque transmission path; and a coupling arrangement for superposing torques transmitted via the first and second torque transmission paths, the coupling arrangement being provided between the input region and the output region, wherein the torsional vibration damping arrangement includes at least in the first torque transmission path a phase shifter arrangement for generating a phase shift of a rotational irregularity transmitted via the first torque transmission path relative to a rotational irregularity transmitted via the second torque transmission path.
