Abstract (en)
[origin: WO2021078321A1] The invention relates to a torque-transmitting device (20) and to a drivetrain (10) for a motor vehicle, wherein the torque-transmitting device (20) has a first input side (60), a second input side (65), an output side (70), a hydrodynamic converter (95), a lockup clutch (100), a first torque-transmitting path (75) which runs between a splitting point (85) and a merging point (95), and a second torque-transmitting path (80) which is configured so as to be parallel with respect to the first torque-transmitting path (75), wherein the hydrodynamic converter (95) is arranged in the first torque-transmitting path (75) and the lockup clutch (100) is arranged in the second torque-transmitting path (80), wherein the first input side (60) is connectable to a crankshaft (35) for conjoint rotation, wherein the hydrodynamic converter (95) has a pump wheel (115) and a turbine wheel (120) which is hydrodynamically connectable to the pump wheel (115), wherein the splitting point (85) is connected to the first input side (60) for conjoint rotation, wherein the pump wheel (115) and a first clutch input side (105) of the lock-up clutch (100) are each connected to the splitting point (85) for conjoint rotation, wherein a second input side (65) is connected downstream of the merging point (90) in a torque flow of a first torque (M1) from the first input side (60) to the output side (70).
