Abstract
A hydrodynamic torque converter and a torsional vibration damper include a pump wheel connected on the drive side and a turbine wheel which is driven by the pump wheel. Between the housing of the torque converter and an output hub, a torsional vibration damper, which includes an input part that can be connected to the housing by a converter bridging clutch, and an output part, which is connected to the output hub, are provided. In order to allow a special wiring of the torsional vibration damper, an intermediate flange is arranged against a respective spring device, which acts in a circumferential direction, between the input part and the output part, said intermediate flange having a centrifugal pendulum and being connected to the turbine wheel.
