AMT变速箱换挡过程的设计分析

Study and Analysis of AMT system shift process

针对换挡控制系统执行机构的控制理论,以各换挡阶段实际的受力情况为出发点,以国家标准28工况为依据,根据试验所测得的原型车性能参数制定动力性和燃油经济性换挡规律,通过对换挡同步过程和同步力影响因素的分析,以及对电动选换挡执行机构作用过程的运动学和动力学研究,计算出了换挡所需的最大同步力,并在此基础上优化换挡执行机构的参数设计。

Internal structure and operating principle of AMT Auto transmission shifting control system are described in the paper. The main focus in shift force in every stage for analysis, which enables start on auto shift control system process analysis, it based on real stress for every shift stage and GB 28 standard work condition, according to the test results from the performance parameter of prototype vehicle to define power and economic shift strategy, via the analysis of shift synchronizing process and syn-chronizing force influencing factor, electric shift actuator action process study on kinematics and dynamics, calculate the max syn-chronizing force on shifting process, on this basis of optimize the parameter design of gear shift structure.
