摘　　要：目前绝大部分轿车自动变速器是采用行星齿轮变速器,多速行星齿轮变速器结构原理和传动比的计算复杂。文章以4T65E自动变速器为例,在分析结构的基础上,建立它的行星齿轮机构的特征方程和速度矢量图,利用传统的公式计算法和杠杆法分别计算行星齿轮机构的传动比,并对两种方法进行对比,从而为自动变速器的传动比计算提供参考?At present automatic transmission of most passenger cars are using planetary gear mechanism.The structure principle and transmission ratio computation of multi-speed planetary gear mechanism are very complicated.Taking 4T65E as an example,the characteristic equations and velocity vector chart of planetary gear mechanism are created based on its structure analysis,both the conventional formula method and lever method are being used to calculate transmission ratio and compared,which in turn provides references for the calculation of transmission ratio of automatic transmission.
