POWER TRANSMITTING APPARATUS FOR HYBRID VEHICLE

摘要

In a power transmitting apparatus (TM) for a hybrid vehicle, including a power split mechanism (4) that splits or combines dynamic power and transmits the power between an engine (1) and a drive shaft (5), and a transmission gear mechanism (17) that changes a rotational speed of the engine (1) through engagement and release of a clutch (C1) and a brake (B1) using hydraulic actuator s (103, 106), the transmission gear mechanism (17) is formed as a transmission gear unit covered with a front cover (108) and a rotary machine cover (118), and the transmission gear unit is mounted to a housing (122) in which the power split mechanism (4) and a motor-generator (2) are disposed, while oil passages (116, 117) for shift control used for supplying hydraulic pressure to the hydraulic actuators (103, 106) are formed in the front cover (108) or the rotary machine cover (118).
