<P>PROBLEM TO BE SOLVED: To improve efficiency of a motor/generator at regeneration time without increasing cost. <P>SOLUTION: A hybrid drive device includes: an engine 1; a gear type multi-stage transmission 2; a starting clutch 3; and the motor/generator 4. A rotor shaft 41 extending in both shaft directions from the motor/generator 4, is arranged in parallel with a crankshaft 15 and a transmission input shaft 21. A first rotor shaft end 41a at an engine side in the rotor shaft 41, and the crankshaft 15 are driven and connected so as to be disconnected by a first gear row 5 and a first one way clutch 7. A second rotor shaft end 41b which is projected to the opposite side to the first rotor shaft end 41a in the rotor shaft 41, and the transmission input shaft 21 are driven and connected so as to be disconnected by a second gear row 6 and a second one way clutch 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
