Power transmission apparatus for automobile

摘要

The invention relates to a power transmission apparatus for use in an automobile, including a gear-type transmission and plural numbers of motors, the gear-type transmission (100) comprises: a first input shaft (23), onto which the motive power is transmitted from an engine (1) through a first friction clutch (25); a second input shaft (24), onto which the motive power is transmitted from an engine (1) through a second friction clutch (26); and plural numbers of gear trains (31-42) between the first input shaft (23) and an output shaft (27), and between the second input shaft (24) and the output shaft (27). Onto the first input shaft (23) and the second input shaft (24) are connected a first motor (29) and a second motor (30), so that the motive power is transmitted from the above two motors through the plural numbers of gear trains (31-42) up to the output shaft (27). Therefore, it is possible to make the maximum torque of the motors small, which is required when changing claw clutches provided on the gear trains (31-42).
