Hybrid TransmissionsMADE BY MAGNA
Hybrid-dual-clutch transmissions are fully scalable from mild to plug-in hybrid. The efficiency of the combustion engine and the electric motor can be used thanks to torque-split technology. This torque-split technology allows use of three powertrain designs on a single platform: a conventional powertrain with an internal combustion engine and dual-clutch transmission, a mild hybrid with an internal combustion engine and a 48 V electric motor integrated into the hybrid transmission, and finally, a plug-in hybrid with an internal combustion engine and a 400 V electric motor integrated into the hybrid transmission.
The hybrid manual transmission 6HMT215 concept offers specific advantages for small and mid-size powertrains as a cost efficient option to create mild hybrid variants based on a 48 V electric system. By using a standardized hybrid part component kit shared with hybrid DCTs, cost and development risks are minimized.
From a vehicle assembly perspective, the integrated solution offers the benefit of a fully-tested unit ready for assembly into the vehicle.
Moreover, the modularity of the concept enables upgrade opportunities to automated hybrid transmissions and to high voltage hybrid units for PHEVs.
