Vehicle drive device

摘要

A vehicle drive device includes an oil pump, a first one-way clutch, a first transmission path configured to transmit a driving force generated in an engine to the oil pump via the first one-way clutch, a second one-way clutch, a second transmission path configured to transmit a driving force from an output shaft of a transmission portion to the oil pump via the second one-way clutch, and a power transmission interruption device configured to interrupt transmission of the driving force generated in the engine to a drive wheel. A speed ratio between the engine and the oil pump in the first transmission path is set to be smaller than a speed ratio obtained by multiplying the smallest speed ratio of the transmission portion by a speed ratio between the transmission portion and the oil pump in the second transmission path.
