摘　　要：行星变速机构是自动变速器的核心组成,是决定自动变速器性能的关键部件,其效率随着结构类型的不同而变化。基于CX31行星齿轮变速机构,分析了其构型特点,计算了传动比及传动效率。以保持速比配置大致不变为条件,对典型对比构型的特点及其传动效率进行了研究,对其可替代性进行了分析。为自主设计重型车辆自动变速箱提供了理论和数据支撑。Planetary gear train is the core of the automatic transmission （AT） and is the key part to decide the performance of the AT. Its efficiency varies with different structure types. Based on the planetary gear train of CX31, the structure characteristic is analyzed, the transmission ratio and trans- mission efficiency are calculated. On the condition that the speed ratio distribution remained largely un- altered, the characteristics and transmission efficiency of another typical configuration are studied. And its alternative is analyzed. It is provided some theoretical and data support for automatic gearbox independent design of heavy vehicle.
