FLOW DETECTING DEVICE OF TRANSMISSION

摘要

PURPOSE: A flow detecting device of a transmission is provided to automatically and exactly detect the lubricant flow in a transmission and to immediately indicate the flow state to a driver by exactly alarming the flow when a vehicle is stopped or traveling. CONSTITUTION: The flow detecting device of a transmission is composed of:a pressure sensor(3) placed on an output meter of a pressurizing pump which circulates by pressurizing the lubricant of a transmission to work when the oil pressure is reduced to the value to be alarmed; a flow sensor(4) detecting if the oil level of the transmission is lower than the value to be alarmed; and a piece(11) accepting the output of the pressure sensor as the alarm output in a traveling mode of a vehicle and the output of the flow sensor as the alarm output in a stopping mode of a vehicle.
