Research Of Automatic CVT Clutch Performance Test Platform Analog Device And Its Control System

Automatic CVT (Continuously Variable Transmission ) clutch is an important component of light motorcycles, it is also a very important safety guarantee of the motorcycle's transmission system. So the quality of automatic CVT clutch will direct influence motorcycle drive reliability. Therefore, test the automatic CVT clutch working performance is especially important.Our country's motorcycle industry has no specialized simulating equipments to test working performance of motorcycle automatic CVT clutch. In order to adapt the motorcycle profession to the check-out facility simulation and the intellectualized demand,and to adapt the requirements of testing a automatic CVT clutch of the motorcycle in the laboratory. I have designed a 'mechanical simulating tester for automatic CVT clutch of the motorcycle'.This thesis mainly carried on the following research work: Go deep into the structure and principle of the automatic CVT clutch, carry on the theories analysis and study of it's working characteristic, then to make a small, intelligentize, practicality simulating tester based on the mechanism, electric and autocontrol structure design, which can do all the tests the national standard requests. The concrete research work has:(1) In the generalized analysis motorcycle automatic CVT clutch structure composition and principle of work, and on the basis of absorption the Original automatic CVT clutch performance test platform merit, overcomes its malpractice,I designed the motorcycle automatic CVT clutch mechanical analogy model performance.(2) With CATIA, I designed a 'mechanical simulating tester for automatic CVT clutch of the motorcycle', and has carried on thepartial structures simulation to proven the test platform structural design rationality and the feasibility. And unified AUTOCAD using the CATIA engineering platfunction to complete the motorcycle automatic CVT clutch test platform mechanical analogy model blueprint design.(3) Choosed sensors, designed the electric circuit of sensor signal recuperation and the electric circuit of system survey control with Protel DXP, and finally I built the test simulation control platform.The completed of this simulating tester will provide abundant but detailed scientific data for the actual test of the automatic CVT clutch; It can guide the motorcycle industry's actually manufacture and test, provide a teaching instrument for the university, graduate school, or the exhibition, and all its working results is a valuable experience for our motorcycle industry.
