ABSTRACT:
A twin-clutch transmission, in particular for a motor vehicle, with a twin-clutch arrangement comprising a first and a second clutch, and a first and a second drive unit designed as an electric machine with a stator and a rotor. The rotor of the first drive unit is fixed to an input side of the transmission that is connected to an engine so that it rotates always at the rotational speed of the engine. The twin-clutch transmission can be switched back and forth between a serial and a parallel hybrid mode, these modes being established by means of the first and second drive units. The drive shaft of the second drive unit and the clutches have different rotational axes.
