汽车无级变速技术的发展现状及展望

Actuality and development of Technologies in Automobile Continuously Variable Transmission

以液力变矩器和行星齿轮系组合的自动变速器,因结构复杂、成本高、维修不便其装车率会逐渐降低,取而代之的将是可以实现传动比连续改变,发动机工况与传动系匹配最佳的无级变速技术。本文主要介绍无级变速技术的概况、工作原理和发展展望。

This paper mainly introduces the outline, basic construction, working theory, technology developing trend and key technology prospect of automotive continuously variable transmission (CVT).
