【Abstract】 The structure characteristics and transmission mechanism of the metal V-belt type continuously variable transmission is introduced in this paper, and a computer model for the performance simulation of vehicles equipped with belt drive CVT is presented. The model simulation can give the dynamic performance simulation of the vehicle under various working condition and provide evaluations of vehicle performance in driveability, fuel economy and emission levels for various drive ranges. Finally, the simulation results are given for several typical driving cycle condition by simulation.更多还原
