Abstract (en)
[origin: WO2021078320A1] The invention relates to a torque transmission unit (15) and a drive train (10), wherein the torque transmission unit (15) comprises a first input side (35), a second input side (40), an output side (45), a hydrodynamic converter (65) and a lock-up clutch (70), wherein the first input side (35) can be torque-transmittingly connected to an internal combustion engine (20) and a first torque (M1) can be introduced into the first input side (35), wherein the torque transmission unit (15) has a freewheel (75), wherein the freewheel (75) is arranged downstream of the hydrodynamic converter (65) and the second input side (40) is arranged downstream of the freewheel (75) in a torque flow of the first torque (M1) from the first input side (35) to the output side (45), wherein the freewheel (75) is designed such that, in a first freewheel operating state, it torque-transmittingly connects the hydrodynamic converter (65) to the output side (45) for the transmission of the first torque (M1) from the first input side (35) to the output side (45) when the lock-up clutch (70) is open, and wherein the freewheel (75) is designed such that, in a second freewheel operating state, it decouples the hydrodynamic converter from the output side (45), in order to at least partially prevent a transmission of the second torque (M2) from the second input side (40) into the hydrodynamic converter (65).
