Abstract:
A torque transmission device between an input side and an output side including a torque converter having a pump, a turbine, a lockup clutch for transmitting a torque between the input side and the output side, and a torsional vibration damper arranged in a casing. The lockup clutch has a clutch input coupled to the casing, a clutch output rotatable relative to the input, and an actuating element for actuating the lockup clutch. The torsional vibration damper has at least one first damper stage comprising a first damper input part and a first damper output part, which can be rotated to a limited extent relative to the first damper input part by the action of at least one first energy storage element, wherein an absorber mass is attached to one of the damper components.
