Device and method of testing temperature of each part of dry clutch

Abstract

The invention discloses a device and a method of testing the temperature of each part of a dry clutch. The device comprises a rack, a variable-frequency motor arranged at the right side of the rack, a fixing shaft arranged at the left side of the rack, a pressure plate arranged at one end of the fixing shaft, and a flywheel arranged on a rotating shaft of the variable-frequency motor, wherein the pressure plate and the flywheel are arranged oppositely, and a friction disk is arranged between the pressure plate and the flywheel; the pressure plate and the friction disk sleeve the fixing shaft from left to right; the pressure plate and the flywheel are rotating parts and are driven by the variable-frequency motor to rotate synchronously, the pressure plate can move axially relative to the fixing shaft, and the friction disk is arranged on the fixing shaft and does not rotate; and multiple temperature acquisition parts are distributed in an array mode on the relative friction surface among the pressure plate, the friction disk and the flywheel. Through the above structural layout, independent temperature data of the pressure plate, the friction disk and the flywheel can be directly acquired, no other transmission paths are needed, and temperature data can be directly read through temperature display screens of the temperature acquisition parts.

Description

technical field [0001] The invention relates to the field of clutch temperature testing, in particular to a temperature testing device and testing method for each part of a dry clutch. Background technique [0002] Clutch is a common component in mechanical transmission. It can separate or engage the transmission system at any time. It is generally installed between the engine and the transmission. It is a component that cuts off and transmits power between the engine and the automobile transmission system. Due to the relative slip between the driving and driven parts, a large amount of heat will be generated to increase the temperature of the clutch. If the temperature exceeds a certain limit, the friction coefficient will be affected, so that the transmitted torque will change, and the wear of the friction plate will be accelerated. In severe cases, the friction plate will burn and lose its effectiveness. [0003] However, due to the rotation and mutual frictional movemen...

Problems solved by technology

Among them, the infrared thermometer can only test the temperature of the outer surface of the component, and cannot reflect the actual maximum temperature of the friction surface; the self-made wireless temperature acquisition system is troublesome to operate, and cannot guarantee the accuracy of temperature measurement; simulation and theoretical calculation can only assist in temperature measurement, does not represent the actual temperature
