Transmission is an important part of vehicle, it can deal with all kinds of driving conditions, to ensure the normal function of the vehicle. As one of the key part of automatic transmission, the snap ring plays an axial role in fixing the components to ensure the accuracy and safety of AT.This paper introduces a development strategy of the snap ring, and carried out a series of comprehensive analysis, such as force analysis, mechanism analysis, design analysis, finite element analysis, manufacturing and assembly process analysis,and got the optimization scheme per the analysis result, then making the limit samples. Through the vehicle test to verify the effectiveness and reliability of the measures, and provide a basis for the optimization, which can effectively improve transimission performance,provides some engineering feasible technical basis for the snap ring of automatic transmission.
