Abstract

A torque-transmitting device has a first input side, a second input side, an output side, a hydrodynamic converter, a lockup clutch, a first torque-transmitting path which runs between a splitting point and a merging point, and a second torque-transmitting path which is configured so as to be parallel with respect to the first torque-transmitting path. The hydrodynamic converter is arranged in the first torque-transmitting path and the lockup clutch is arranged in the second torque-transmitting path. The hydrodynamic converter has a pump wheel and a turbine wheel which is hydrodynamically connectable to the pump wheel. The splitting point is connected to the first input side for conjoint rotation. The pump wheel and a first clutch input side of the lock-up clutch are each connected to the splitting point for conjoint rotation. A second input side is connected downstream of the merging point in a torque flow of a first torque from the first input side to the output side.
