<p><P>PROBLEM TO BE SOLVED: To provide an energy regeneration device for a vehicle, including a first rotary electric machine and a second rotary electric machine, in which only the first rotary electric machine is made to function as an electric generator in a simple structure without requiring complicated mechanism and control. <P>SOLUTION: The energy regeneration device 21 for the vehicle includes: a planetary gear mechanism 30 which combines the rotational drive force of a first shaft 26 rotationally driven by a first rotary electric machine 24 and the rotational drive force of a second shaft 66 rotationally driven by the second rotary electric machine 64 and transmits the combined rotational drive force to a drive shaft 32 with the rotational speed increased. The rotational drive force of the second shaft 66 is transmitted to the planetary gear mechanism 30 via a first power transmitting mechanism 68. In the planetary gear mechanism 30, there is provided a clutch mechanism 58 for allowing transmission of rotational drive force from the second shaft 66 to the planetary gear mechanism 30 while blocking transmission of rotational drive force from the planetary gear mechanism 30 to the second shaft 66. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
