摘要

The drive train comprises a combustion engine, which has a crankshaft (1), a transmission, which comprises a transmission input, and a coupling unit (3,8) arranged between the crankshaft and the transmission input, by which the crankshaft is coupled with the transmission input. The coupling unit has an air guiding element (15,16), which produces an air flow by the rotation of the coupling unit, which cools an electrical machine (12).
