POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve mounting performance to a vehicle by reducing the size and weight of a power transmission device.

SOLUTION: This power transmission device includes a first shift means 5 and a second shift means 7 for forming a plurality of shift stages. A first input side transmission shaft 10 is connected to a first input shaft 4 of the first shift means 5 via a first input clutch 12. A second input side transmission shaft 14 connected to the first input side transmission shaft 10 is connected to a second input shaft 6 of the second shift means 7 via a second input clutch 13. Rotation from an internal combustion engine 2 is inputted into a first rotation element Rf. The first input side transmission shaft 10 is connected to a second rotation element Cf. The power transmission device includes a power synthetic mechanism 11 for inputting rotation from an electric motor 3 into a third rotation element Sf. The power synthetic mechanism 11 includes an engaging element 29 for connecting and disconnecting the first rotation element Rf and the second rotation element Cf.
