Abstract
A hydrodynamic coupling includes a housing coupled to a driveshaft having an impeller and a turbine wheel arranged in the housing driven by the impeller and a first damper arrangement by which the housing is coupled to a driven member by a lockup clutch. The first damper arrangement includes a first torsional vibration damper connected to the lockup clutch that is rotatable around an axis of rotation against the action of a first damper spring arrangement. A second torsional vibration damper is connected to the first torsional vibration damper and rotatable around the axis of rotation against the action of a second damper spring arrangement. The turbine wheel is connected to an intermediate torsional vibration damper region including a first secondary side, a second primary side, a second damper arrangement has a deflection mass carrier connected to the second secondary side.
