摘要

搭建了金属带式无级变速器传动系统的数学模型,并通过实例仿真分析了CVT速比变化特性对车辆加速度的影响。研究结果证明,CVT速比变化率能够在一定程度上影响车辆加速度,应当根据速比变化的方向适当地控制速比变化率。该项研究工作为CVT速比变化率的控制策略提供了理论上的依据和方法。

Abstract

The mathematic model of the metal pushed V- belt continuously variable transmission is established,and the influence of CVT speed ratio variation on the vehicle acceleration is analyzed and simulated through the example. The research result proves that the changing rate of the speed ratio affects on the vehicle acceleration to a certain extent. As the result,the changing rate of the speed ratio should be controlled according to the direction of the changing. Through the research,the theoretical foundation and method are provided for the control strategy of the CVT speed ratio changing rate.
