Abstract
A torque transmission unit includes a first input side, a second input side, an output side, a hydrodynamic converter and a lock-up clutch. The first input side is configured to receive a first torque, and the second input side is configured to receive a second torque. The torque transmission unit has a freewheel. The freewheel is arranged downstream of the hydrodynamic converter, and the second input side is arranged downstream of the freewheel in a torque flow of the first torque from the first input side to the output side. The freewheel is designed to, in a first freewheel operating state, connect, in a torque-locking manner, the hydrodynamic converter to the output side for the transmission of the first torque from the first input side to the output side when the lock-up clutch is open. The freewheel is designed to, in a second freewheel operating state, decouple the hydrodynamic converter from the output side, to at least partially prevent a transmission of the second torque from the second input side into the hydrodynamic converter.
