Simulation Analysis of Synchronization Process of Single Cone Lock Ring Synchronizer Based on ADAMS

摘要: 针对汽车变速器企业在研发阶段便能获取相关换挡参数的需求，以手动式带单锥锁环式同步器的工程车用变速器为研究对象，建立三、四档变速器换挡系统的三维简化模型；利用ADAMS软件对影响换挡动作的主要构件进行运动副设置，并根据实际情况添加与输入端、输出端的转动惯量等效的转动圆盘，建立运动仿真模型；设置输入端、输出端的转速和换挡轴的换档力，仿真得出齿圈、锁环、结合齿的速度曲线以及接合齿对齿圈的冲击力曲线。仿真结果与实际换挡过程基本吻合，为企业提供了一套变速器换挡系统虚拟样机仿真测试的操作方法，对产品优化设计有一定借鉴作用。

Abstract: In order to meet the needs of automobile transmission enterprises in the research and develop-ment stage to obtain the relevant shift parameters, taking the manual engineering vehicle trans-mission with single cone lock ring synchronizer as the research object, the three-dimensional simplified model of three and four speed transmission shift system was established; the motion pairs of the main components affecting the shift action were set by using ADAMS software, and the input and output ports were added according to the actual situation, and the motion simulation model was established. By setting the speed of input and output end and the shift force of shift shaft, the speed curve of ring gear, lock ring, combined gear and the impact force curve of joint gear on ring gear were obtained by simulation. The simulation results are basically consistent with the actual shift process, which provides a set of operation method for virtual prototype simulation test of transmission shift system for enterprises, and has a certain reference value for product optimization design.
