Patent ID: 7393296

Claim:
A hybrid driving unit comprising: an input shaft for inputting motive power from an internal combustion engine; an output shaft disposed on an axis in line with said input shaft and engaged with driving wheels; a first electric motor disposed on said axis and comprising a stator and a rotor; a power-splitting planetary gear disposed on said axis and comprising a first rotary element coupled with said input shaft, a second rotary element coupled with said rotor of said first electric motor and a third rotary element coupled with said output shaft; a second electric motor disposed on said axis and comprising a stator and a rotor; and a transmission disposed on said axis, which shifts and transmits revolution of said rotor of said second electric motor to said output shaft; wherein said first electric motor, said power-splitting planetary gear, said second electric motor and said transmission are provided in a casing member while being disposed in line on said axis; wherein said stators of said first and second electric motors are fixed to said casing member; wherein said first electric motor, said power-splitting planetary gear, said second electric motor and said transmission are disposed on said axis such that said second electric motor and said transmission are positioned on a side of a vehicle closer to said internal combustion engine than said first electric motor and said power-splitting planetary gear; and wherein said transmission is an automatic transmission having at least two stages or a continuous variable transmission.
