It is a key process for the automatic transmission design to study and analyze the dynamic characteristics of the planetary gear mechanism. Applying whole vector method, the paper analyzes the power transmission route of the double-row planetary gear mechanism’s automatic transmissions on five independent motion components. The transmission ratios under dif-ferent gears are also calculated according to the triangle similarity theory. Combining with the speed vector graph , the lifting gear process of such kinds of automatic transmission is further analyzed. The whole vector method is of great help to qualitative analy-sis of the automatic transmission’s power transmission characteristics and quantitative calculation of transmission ratio and ele-ment speed.
