Title:
LUBRICATION STRUCTURE OF HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2020082963
Kind Code:
A
Abstract:
To suppress the enlargement of an agitation loss in a lubrication-necessary part caused by the excess of a flow rate in an axial core oil path.SOLUTION: A lubrication structure of a hybrid vehicle comprises: a cooling oil path for supplying oil for cooling a motor to the motor; a lubricant path branched from the cooling oil path, and supplying oil for lubricating a lubrication-necessary part of a power transmission device to the lubrication-necessary part; and an electric oil pump for discharging the oil supplied to the cooling oil path and the lubricant path. The lubricant path includes a supply oil path formed of a hollow supply pipe 102 connected to an end part of an input shaft 6, extending along an axial direction in the supply pipe 102, and communicating with the axial core oil path. The input shaft and the supply pipe rotate at HV-traveling, however, do not rotate at EV-traveling. A spiral part is arranged at an internal peripheral face of the supply pipe, and a non-rotation center shaft is inserted into the supply pipe along the axial direction.SELECTED DRAWING: Figure 2
