Title:
VEHICLE POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2015200357
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a lubrication structure capable of ensuring an appropriate quantity of lubricating oil in response to a vehicle velocity or a transmission gear ratio so as to attract the lubricating oil into an inner peripheral side space of an outer member from outside in response to the oscillation of a one-way clutch.SOLUTION: A vehicle power transmission device includes a plurality of power transmission mechanisms disposed in an axial direction for changing the number of revolutions of an input shaft and transmitting the changed number of revolutions to an output shaft, oil passages 51 are formed in an outer member 22 to extend from an inner peripheral surface 22a side to an outer peripheral surface 22e side, an end portion 51a on an inner peripheral surface side of each oil passage 51 is provided to have a state of being located below an oil level h of lubricating oil stored in a case containing therein the power transmission mechanisms, and an end portion 51b on an outer peripheral surface side of the oil passage 51 is provided closer to a direction S1 of cancelling engagement than the end portion 51a on the inner peripheral surface side in a direction of oscillating the outer member 22.
