Abstract: 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.

前 言
自动变速箱是汽车动力传动系统的重要组成部分,其内部结构极其复杂,而结构的复杂性导致其容易发生故障。变速箱的故障会直接影响整车的动力性能和驾驶性能,严重情况下会影响到车辆的行驶安全。多片式离合器做为自动变速箱的关键部件之一,决定了变速箱是否能够正常工作,目前常使用卡簧对多片式离合器的轴向位置进行限制,防止相关零部件的轴向移动超出其允许的工作范围,而出现动力输出异常,使其能够正常工作,以保证变速箱元件工作状态的稳定和可靠[1-3]。……
