POWER TRANSMISSION DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a power transmission device for vehicle which is compact as much as possible.

SOLUTION: This power transmission device includes: an oil pump 52 linked with an input shaft 14 through a clutch 60; and an auxiliary motor Ms in which the oil pump 52 is drivably set up. The device can be miniaturized by commonalizing those configurations by: driving the oil pump 52 with the engine 10 in engagement with the clutch 60 when running with the engine 10 as a driving power source; driving the oil pump 52 with the auxiliary motor Ms, while intercepting power transmission between the oil pump 52 and auxiliary motor Ms, and the input shaft 14 by releasing the clutch 60 when running with the second motor M2 as a driving power source; and starting the engine 10 with the auxiliary motor Ms for driving the oil pump 52 since the start of the engine 10 is performed with the auxiliary motor Ms in engagement with the clutch 60 when starting the engine 10.
