ABSTRACT:
A hybrid gear train of a motor vehicle that has an internal combustion engine with a drive shaft, an electric motor with a rotor that operate as a motor and a generator, a transmission with two input shafts and an output shaft, as well as a differential transmission. At least one of the input shafts can be connected, via an assigned de-coupler, to the drive shaft, both of the input shafts can be connected by alternately assigned gearwheel sets of different ratios and in each case one assigned gear clutch to the output shaft. The differential transmission is designed as a simple planetary gearset that is coaxial with the first input shaft. The ring gear of this transmission is rotationally fixed to the one input shaft. The planet carrier is rotationally fixed to the second input shaft, and the sun gear is connected to and drives the rotor.
