| 摘 要： | 在回流式无级自动变速传动系统调速特性和传动效率分析的基础上，以提高效率为出发点。通过对原有系统低速档、倒档工况下的效率分析，并对原有结构进行了优化．对传动系统的最大速比、最小速比和倒档速比进行了计算分析，提出了回流式无级自动变速传动系统的结构参数设计方法,以长安羚羊SC7101轿车为设计原型，在保持原车性能的基础上给出了对原型车的回流式无级自动变速的改造实例．

| Abstract: | On the purpose of improving efficiency of continuously variable transmission with reflux power,efficiency of previous system under low gear and reverse gear have been analyzed to optimize its structure based on analysis of speed modulation characteristic and transmission efficiency of transmission system.What's more,with maximum speed ratio,minimum speed ratio of transmission system and speed ratio of reverse gear having been calculated,design method of structural parameters has been brought out.Finally,SC7101 as reference,design on structural parameters of continuously variable transmission with reflux power has been presented on the base of performance of previous structure. |
