摘　　要：简介了封闭行星轮系特性图和功率分配系数Pf的计算法,查表可确定功率流形态。又采用了求J直线和t直线交点,按图由交点直接确定功率流种类的方法。以一种重型车辆用无级变速机为实例,应用这些"特性图"和经改进的"传动比法"对其进行了运动分析、功率流分析、效率分析。Characteristic diagram J of planetary differential and the installation of partition ratio of power Pf are introduced. Species of power flow can be determined by tables. Another way of determining the species of power flow is through the point of intersection of straight line J and straight line t. When the meshing efficiency is computed. The improving law of the train ratio is used. In the end, an example of a differential gear variable speed transmission for heavy - duty vehicles is given.
