Title: TORSIONAL VIBRATION DAMPER AND HYBRID DRIVE TRAIN
Abstract:
The invention relates to a torsional vibration damper (200), especially a dual mass flywheel, comprising an input part (204) and an output part (206) with a common axis of rotation (210), about which the input part (204) and the output part (206) can be rotated together and twisted in a limited manner in relation to each other, and a spring-absorber device (212) that acts between the input part (204) and the output part (206), wherein the output part (206) comprises a coupling device (202) with an input side (232) and an output side (234), which can be moved between an open actuating position and a closed actuating position, the coupling device (202) transmitting a torque from the input side (232) to the output side (234) in the closed actuating position, and the output side (234) of the coupling device (202) comprising a spring arrangement (252) which, in the closed actuating position of the coupling device (202), transmits the torque from a first component (246) of the output side (234) to a second component (262) of the output side (234). The invention also relates to a hybrid drive train (100) with an internal combustion engine (106) and an electric machine (108), the hybrid drive train (100) comprising such a torsional vibration damper (200).
