摘　　要：汽车自动变速器通常采用多行星排结构,行星排之间组合关系较为复杂。采用杠杆法分析了两行星排的可能传动方案,并介绍了自动变速器中常用的一些机构类型及其结构特点。针对杠杆法,在分析两行星排自动变速器传动中的缺陷和不足后,对其进行完善。运用新拓展后的杠杆法对5L40E自动变速器各挡位的传动进行分析,验证了拓展后的杠杆法和分析的正确性。Automatic Transmission usually adopts multiple row planetary gear structure. The relations between planetary row combination are complicated. In this paper, the lever analogy method is used to analysis possible transmission scheme, structural composition, the possible connections between different components. In the light of the defect and deficiency of the lever method in the analysis of the transmission of two planetary gear transmission, it is expanded. By using the new extended lever analogy method,the transmission of each shift of the 5L40E automatic transmission is analyzed. And the correctness of the analysis is verified. It lays the foundation of searching the best transmission scheme.
