基于磨损失效原理的无级变速器可靠性试验研究
Test research on continuously variable transmissions' reliability based on principle of wear failure
摘要
Abstract
According to the demands of continuously variable transmission(CVT)'s clamping force control strategy for CVT's reliability,a durability test bench is designed.In consideration of the characteristics of the speed shifiting mechanism and traditional clamping force control during sliding transmission,a clamping force test bench is devel-oped based on the method of using mechanical limit to fix the speed ratio.Based on the principle of metal strip slip and the results of friction coefficient test,the failure chart of the transmission mechanism is plotted with the help of Matlab,and the lurbricating oil selection standard for CVT is given.A real vehicle with CVT is tested on the road of 30000km to compare the metal ion contents in lubricating oil before and after the road test,and the inside com-ponent aging is predicted by using the iron spectrum method,resulting in the predicting error rate of only 1.02%. The simulation verified the effectiveness of the test bench.It has the better stability and robustness when testing CVT's reliability.关键词
