<P>PROBLEM TO BE SOLVED: To provide a hybrid transmission capable of performing high-output operation of lock-up gear ratio by setting a lock-up gear ratio fixing mode capable of fixing the gear ratio to 1:1 of lock-up gear ratio. <P>SOLUTION: Pairs of planetary gear GR, GC and GF and pairs of motor/generator MG1 and MG2 are coaxially provided in order from a side far from an engine ENG. An input shaft 3 connected to the ENG is connected to a carrier Cc and a ring gear Rr through an engine clutch Cin, and an output shaft 4 is connected to a carrier Cr. The MG1 is connected to a ring gear Rc, and the MG2 is connected to a sun gear Sf, and this sun gear Sf is connected to a sun gear Sc. The carrier Cf and the sun gear Sf can be connected to each other by a high clutch Chi, and this carrier Cf can be fixed by a low brake B<SB>LO</SB>, and the ring gear Rf is connected to a sun gear Sr. A lock-up clutch Cdi is provided to connect both the ring gear Rr and the sun gear Sr of the pair of planetary gear GR, which connects both the input shaft 3 and the output shaft 4 to each other, and since the lock-up clutch Cdi connects between the ring gear Rr and the sun gear Sr, rotation from the input shaft 3 can be taken out from the output shaft 4 (Out) through the carrier Cr, and gear ratio can be fixed to 1:1 of lock-up gear ratio. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
