车轮外倾角与前束合理匹配的研究

Research on the Rightful Matching with Toe-in and Camber of Wheels

主要对四轮定位参数中最重要的也是对车辆使用影响最大的两个参数———外倾角和前束的合理匹配关系进行了详细的研究。提出了3种确定最佳匹配的方法:即根据轮胎特性计算外倾角和前束值的合理匹配关系式;根据轮胎工作中无横向滑移时建立了外倾角和前束值的合理匹配关系式;根据轮胎接地印迹长度建立外倾角和前束值的合理匹配关系式。

In this paper, an exhaustive research on the rational matching relations between the camber angle and the toe-in ,which are the two most significant parameters in that of locating vehicle＇ s four wheels and have great influence on the vehicle perfermenoe ,has been carried out. Then three means of optimal matching are presented： On the basis of the tyre＇ s properties calculation to build up the equation reflecting the rational matching relations;According to the condition where no tyre＇ s horizontal stiding to establish the equation and based on the tyre＇ s grounding mark length to set up the equation.
