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.

Hybrid drive train for a motor vehicle

A hybrid drive train of a motor vehicle which comprises a combustion engine, an electric machine which is operable as a motor and a generator and comprises a stator and a rotor, and a multi-stage planetary transmission with input and output shafts. The driveshaft of the combustion engine can be connected to the input shaft of the transmission, the electric machine is coaxially arranged about the input shaft, and the rotor of the electric machine is rigidly connected with the input shaft. To achieve a starting acceleration and climbing capacity on starting, corresponding to those provided by a drive train with an automatic transmission and a hydrodynamic torque converter or a manual gearshift transmission with a converter shifting clutch, the rotor of the electric machine can be connected with the transmission input shaft via an input transmission stage which is formed as a simple planetary gearset and has a high gear ratio.
