摘　　要：通过研究调整转向传动轴两个万向节叉的相位角的方法,以瞬时传动比的波动最小作为优化目标,达到了改善汽车转向性能的目的。借助Matlab软件,将该优化方法运用于某轻型商用车转向传动系统的优化设计中,按优化方案试制样件并在实车上进行试验,试验结果验证优化方法是有效可行的。The optimization method of the instantaneous transmission ratio of the steering transmission system with double cross universal joints is researched. The steering performance is im- proved by adjusting the phase angle of the yokes on the steering shaft, with the minimum fluctuation of the instantaneous transmission ratio as the object. The optimization method is used to design of the steering transmission system of one light commercial vehicle by Matlab. The sample parts are tested ac- cording the optimization scheme, and the test result verifies it is feasible and effective.
