Title:
LUBRICATION STRUCTURE FOR HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2016168950
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lubrication structure for a hybrid vehicle that enables oil to be supplied appropriately to a gear transmission mechanism for transmitting outputs from an engine and a motor to a driving shaft side.SOLUTION: In a lubrication structure for a hybrid vehicle using an engine, a first motor 2 and a second motor as driving power sources and including: a planetary gear mechanism PG in which the first motor 2 is connected to a sun gear 6, an output shaft is connected to a ring gear 7 and the engine 1 is connected to a carrier 8; a brake mechanism 10 for selectively stopping and fixing the rotation of the carrier 8; an oil pump 21 operated by a third motor to generate hydraulic pressure; and an oil supply mechanism 22 that uses the oil pump 21 as a hydraulic source to supply oil to the planetary gear mechanism PG, the oil supply mechanism 22 is configured to pressure-feed the oil to an axial center portion of a pinion gear 9 of the planetary gear mechanism PG by generating hydraulic pressure by using the oil pump 21.SELECTED DRAWING: Figure 2
