<P>PROBLEM TO BE SOLVED: To solve the problem wherein mechanical connections among a motor generator 10, an engine 12, a driving wheel 14 and a power split device 20 are not suitable in some traveling area of a vehicle. <P>SOLUTION: The power split device 20 is constructed by connecting a ring gear R and a sun gear S of a first planetary gear mechanism 22 to a carrier C and a sun gear S of a second planetary gear mechanism 24, respectively. A rotating shaft 10a of the motor generator 10 is connected to a ring gear R of the second planetary gear mechanism 24, and connected to the sun gear S of the first planetary gear mechanism 22 and the sun gear S of the second planetary gear mechanism 24 through a CVT 36 and a clutch C1. The driving wheel 14 is mechanically connected to the ring gear R of the first planetary gear mechanism 22 and the carrier C of the second planetary gear mechanism 24, and mechanically connected to the sun gear S of the first planetary gear mechanism 22 and the sun gear S of the second planetary gear mechanism 24 through a clutch C2 and the CVT 36. <P>COPYRIGHT: (C)2011,JPO&INPIT |
