Problems solved by technology

However, since the sensor needs to be fixed on the rotating part, it is impossible to use the method of direct wire connection for power supply, transmission and data detection, which makes it difficult to collect the temperature and torque data of the existing clutch. The emergence of testing methods for torque and temperature collection is imminent

Abstract

The invention discloses a clutch torque and temperature testing method, which adopts a wireless transmission and wireless power supply mode for measurement, that is, a stator supplies power to a rotor in an induced electromotive force mode, the rotor sends a frequency signal to the stator in real time, and after being amplified, the signal is received by the receiving device, correspondingly processed and then output in an analog quantity manner. Torque and temperature signals are connected with an automobile CAN bus, data acquisition and analysis are facilitated, an AD / CAN device is additionally arranged, the analog quantity signals of the torque and the temperature are converted into CAN signals through the AD / CAN device, and the CAN signals are transmitted to the bus. When data needs to be collected, the data can be collected from the bus through special equipment, and corresponding analysis and processing are carried out.

Description

Technical field [0001] The present invention belongs to the field of vehicle design, involving a clutch torque and a temperature test method. Background technique [0002] The transmission is an important part of the automobile power transmission system, which has an important role in the power of the car, the comfort and fuel consumption of the car, and the clutch is an important constituent structure on the transmission, and the clutch is frequently engaged and slippery, so that the friction sheet Wear, the heat generated during the frictional sliding process increases the temperature of the friction plate, when the working surface temperature exceeds 200 ° C, the frictional wear has increased dramatically, the friction material used in the clutch, the critical temperature of the working critical temperature is about 400 ° C More than this temperature, the friction piece will be permanently damaged due to ablation, in order to extend the service life of the clutch friction, the...
