Patent ID: 8490727

Claim:
A hybrid drive train for a motor vehicle, the hybrid drive train comprising: an internal combustion engine, an electric machine with a stator ( 1 ) and a rotor ( 2 ), and a transmission in which a separator clutch ( 4 ), in a form of a disk clutch being arranged in a force flow direction between the internal combustion engine and a transmission input shaft ( 3 ), having an outer disk carrier ( 5 ) connected in a rotationally fixed manner to an element of a transmission input stage and an inner disk carrier ( 7 ) connected to the internal combustion engine, the rotor ( 2 ) of the electric machine driving another element of the transmission input stage, the electric machine, the separator clutch ( 4 ) and the transmission input stage comprising an unit, the outer and the inner disk carriers ( 5 , 7 ) of the separator clutch ( 4 ) being mounted and centered by two roller bearings ( 11 , 12 ) which center the inner disk carrier ( 7 ) and the outer disk carrier ( 5 ) relative to one another and bring the inner and the outer disk carriers ( 7 , 5 ) into axial alignment, and axial tolerances produced within the unit, during operation of the motor vehicle, being compensated by displacing and aligning a disk packet of the separator clutch ( 4 ) in a drive gearing of the inner disk carrier ( 7 ); wherein the transmission input stage is a planetary transmission unit and the outer disk carrier ( 5 ) is connected to a planetary carrier ( 6 ) of the planetary transmission unit, the rotor ( 2 ) of the electric machine drives a ring gear ( 8 ) of the planetary transmission unit and a sun gear ( 9 ) of the planetary transmission unit is coupled to a housing.
