摘　　要：汽车转向梯形是一个由“齿轮-齿条”驱动的连杆运动机构,与悬架机构一起控制轮胎转向与跳动,影响转向阿克曼率、转向传动比、齿条力等转向性能。基于大量标杆车台架试验数据,给出转向梯形关键设计参数;同时论证了基于同一套前悬架系统,前置转向梯形变为后置转向梯形的可行性。利用Catia V5参数化模型和Adams前悬架运动仿真模型,对某混动车转向梯形进行了概念设计,很大程度上实现了转向系统平台化,减少了开发成本,可为汽车工程师提供设计参考。The steering trapezoid of automobiles can be seen as a link mechanism.It controls the motions of the tyres and influences on the steering Ackermann rate,steering gear ratio,rack force,and so on.A list of steering trapezoid's design parameters based on the benchmark data is given in the study.Front steering trape⁃zoid can be replaced of rear steering trapezoid in the same front suspension system that is proved in this study.The steering trapezoid of a hybrid power automobile is designed taking advantages of Catia V5 parameterized model and front suspension motion model based on Adams.Low cost and low design risk come true through the design method of the steering trapezoid.
