Abstract

A hybrid drive train for a motor vehicle comprises an internal combustion engine, and electric machine, with a stator and rotor, and a transmission. A disk clutch is located in the force flow, between the combustion engine and the transmission input shaft, and an outer disk carrier of the disk clutch is fixed to a transmission input stage and an inner disk carrier of the disk clutch is connected to the combustion engine. The rotor of the electric machine drives another element of the transmission input stage, and the disk carriers of the clutch are mounted and centered by two roller bearings which center the inner and outer disk carriers relative to one another and bring them into axial alignment, and axial tolerances within the unit which comprises the electric machine, the separator clutch and the transmission input stage are compensated by displacing and aligning the disk packet of the clutch in the drive gearing of the inner disk carrier.
