Abstract

The invention relates to a hydrodynamic torque converter having an impeller wheel, a turbine wheel and an oscillation damper which is accommodated in the converter housing, and a converter lockup clutch. Two damper stages are arranged here as a serial damper between the output hub of the torque converter and the converter lockup clutch, and a damper stage is arranged between the turbine wheel and the output hub. In order to improve the damping properties, a rotary oscillation absorber is additionally provided which is arranged between the dampers and is also connected to the turbine wheel in a rotationally fixed fashion.
