- the invention is intended for use with dry friction clutches 16 or separating clutches, especially K0 modules in P2 arrangements.
- the strategies shown can, however, be transferred directly to other applications, preferably with hybridized drive trains. Particular mention should be made of triple couplings and K1 modules for dedicated hybrid transmissions.
- an internal combustion engine is connected via a crankshaft to the friction clutch 16 designed as a multi-plate clutch, which is designed as a K0 or disconnect clutch for separating and connecting the internal combustion engine from the hybrid drive train.
- the multi-plate clutch is designed concentrically with an electrical machine 14. Torque can be transmitted to the wheels of the motor vehicle via an output shaft 20.
- the output shaft 20 can be connected to the multi-disk clutch and the electrical machine 14.
- the multi-disc clutch is integrated in particular in a rotor of the electrical machine 14.
- the electric machine 14 is preferably an electric motor and / or an electric generator.
