- Abstract:
- The clamping force control of continuously variable transmission was studied,and the traditional force control strategy was improved.The slip mechanism of metal belt and pulley was analyzed,with the description of the slip phenomenon.The influence of slip ratio on the belt wheel drive was studied,and the mathematical model was established by the test data.The combined simulation model based on AMESim and Simulink was established.Combined with simulation results,the new control strategy and the traditional control strategy are compared.The simulation results showed that the clamping force was reduced to the original 85％-90％ with the new control strategy.The new control strategy made transmission efficiency maintained between 80％ to 85％,with throttle opening increased from 10％ to 50％.In extreme conditions,the slip rate control would produce a certain degree of slip rate fluctuations,which might need further improvement.
