<P>PROBLEM TO BE SOLVED: To provide a transmission for a hybrid vehicle capable of relaxing an interruption of driving force even at any switching in each gear change stage of a gear change mechanism, and improving the drivability of the vehicle. <P>SOLUTION: The transmission 20 for the hybrid vehicle 1 includes a planetary gear 30 and the gear change mechanism 40. The planetary gear 30 has a first element 31 connected to an internal combustion engine 11, a second element 32 of which a rotation is allowed and prohibited by a brake Brk, and a third element 33 connected by the first element 31 and the clutch Crt. The gear change mechanism 40 includes an input shaft 41 connected to the third element 33, the output shaft 42 connected to a driving wheel, and a plurality of gear sets. In the gear set having a minimum speed reduction ratio out of the plurality of gear sets of the gear change mechanism 40, each gear is engageably and disengageably supported on the input shaft 41 and the output shaft 42 respectively, and one of the gear out of the gear set having the minimum speed reduction ratio is connected to an electric motor 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
