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.

Abstract: The invention relates to a vibration damping device in a drive train of a motor vehicle, having an input drive part and an output part that is rotatable to limited extent relative to the input part through the action of at least one energy storage element, there being a pendulum mass carrier situated or formed on the input part and/or the output part, which makes it possible to receive at least one pair of pendulum masses comprising pendulum masses that are situated opposite each other axially on the pendulum mass carrier and are pivotable to a limited extent relative to the latter with the aid of at least one roll-off element, and where the roll-off element, by rolling, passes over a roll-off surface on the pendulum mass carrier and on each of the pendulum masses as the pendulum masses move relative to the pendulum mass carrier, and where the pendulum masses of a pair of pendulum masses have different geometric forms.
