POWER TRANSMITTING APPARATUS FOR HYBRID VEHICLE

摘要

A power transmitting apparatus (TM) for a hybrid vehicle includes a power split mechanism (4), a transmission gear mechanism (17) and a support (118). The power split mechanism (4) includes a differential device provided with a first/second/third rotation elements. The power split mechanism (4) splits and transmits dynamic power to a drive force source and the drive shaft (126). The transmission gear mechanism (17) changes speed of an engine (1) and transmits a torque to the first rotation element (8), and the elements are arranged in an order of the transmission gear mechanism (17), a rotary machine (2), and the power split mechanism (4) from a side closer to the engine (1). The support (118) is arranged between the transmission gear mechanism (17) and the rotary machine (2), supporting a rotating shaft (2a) of the rotary machine (2), and configured to allow lubricant to enter (118b) the rotary machine side from the transmission gear mechanism side.
