DRIVE DEVICE FOR HYBRID VEHICLE

摘要

A drive device (1-1) for a hybrid vehicle is provided with a first planetary gear mechanism (10), a second planetary gear mechanism (20), a clutch (4) which connects and disconnects the carrier (14) of the first planetary gear mechanism and the ring gear (23) of the second planetary gear mechanism, and a brake (5) which engages to restrict the rotation of the ring gear of the second planetary gear mechanism. The second planetary gear mechanism is of a double pinion type. The sun gear (11) of the first planetary gear mechanism is connected to a first dynamo-electric machine (MG1), the carrier (14) thereof is connected to the engine (1), and the ring gear (13) thereof is connected to the drive wheels. The sun gear (21) of the second planetary gear mechanism is connected to a second dynamo-electric machine (MG2) and the carrier (24) thereof is connected to the drive wheels.
