| Abstract: | The metal V belt type continuously variable transmission(CVT)for vehicles is one kind of advanced transmission device.The construction of hydraulic system and the basic operating principle of hydraulic servo control for CVT was described. The relations between the rotating speed of the engine and the running speed of the vehicle were analyzed. With the help of bond graph method,the mathematical model of the system was established in the style of state equation.The study of this project provides the academic bases for further studying on the dynamic characteristics of continuously variable transmission and vehicle. |
