Abstract:
1. A hybrid drive apparatus comprising: an input shaft for inputting motive power from an internal combustion engine; an output shaft that is disposed in alignment with said input shaft on an axis and that operates in association with a driving wheel; a first electric motor that is disposed on said one axis and that has a stator and a rotor; a motive power distributing planetary gear that is disposed on said axis and that has a first rotating element connected to said input shaft, a second rotating element connected to the rotor of said first electric motor, and a third rotating element connected to said output shaft; a second electric motor that is disposed on said axis and that has a stator and a rotor; and a transmission that is disposed on said axis, and that speed-shifts rotation of the rotor of said second electric motor and then transfers rotation to said output shaft, wherein said first electric motor, said motive power distributing planetary gear, said second electric motor and said transmission are housed in a case member, and are aligned and thus disposed on said axis with said motive power distributing planetary gear being at a foremost end side, and said stators of said first electric motor and said second electric motor are secured to said case member, and wherein said output shaft is divided into a first output shaft and a second output shaft, and joined so as to rotate together, and wherein said third rotating element of said motive power distributing planetary gear is coupled to said first output shaft, and said transmission is coupled to said second output shaft.
