Title:
CONTROL METHOD FOR TRANSMISSION AND LUBRICANT PRESSURE CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2021/111802
Kind Code:
A1
Abstract:
In the present invention, a transmission comprises: a transmission mechanism that executes a gear shift for rotational power inputted from an engine; an oil pump that discharges oil supplied to the transmission mechanism; a lubricant pressure control valve that adjusts the pressure of the oil discharged from the oil pump, and supplies the oil to a lubrication part of the transmission mechanism; and a cooler that cools the oil supplied to the lubrication part of the transmission mechanism using external air. Furthermore, the lubricant pressure control valve adjusts the pressure of the oil supplied to the lubrication part such that, the lower the external air temperature is, the higher the lubricant pressure of the oil supplied to the lubrication part becomes.
