摘　　要：宝马五挡自动变速器采用并联三排行星齿轮机构,传动原理和传动比的计算复杂。文章以ZF5HP24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,利用杠杆法计算行星齿轮机构的传动比,此方法直观,可以为其它自动变速器的传动比计算提供参考?BMW 5-speed automatic transmission driven by parallel 3-row planetary gear mechanism,its drive principle and transmission ratio computation are complicated.Taking ZF5HP24 as an example,the characteristic equations and velocity vector chart of planetary gear mechanism are created based on its structure analysis.The transmission ratio is calculated by lever method.This method is visual and can provide references for the calculation of transmission ratio of other automatic transmissions.
