Abstract: In the article, the interference of steering torque which produced by the McPherson suspension Anti-Roll bar's linkage has been analyzed, the conception of equivalent steering arm is introduced to quantitatively analyze the influence. By setting the different position of the Anti-Roll bar's linkage, the effects of different equivalent steering arm values on the suspension wheel jump steering performance and the vehicle dynamic steering characteristics are compared and analyzed. After collecting the statistical analysis of the equivalent steering arm value of several front McPherson Anti-Roll bar's linkages, recommend the reasonable equivalent steering arm value for vehicle, provide an effective data for guiding the suspension Anti-Roll bar design.

摘要： 文章对麦弗逊悬架横向稳定杆吊杆布置对车轮转向产生的干扰转向力矩进行分析,引入等效转向力臂的概念,对影响程度进行量化分析。设定稳定杆吊杆的不同位置,对比分析不同的等效转向力臂值对悬架轮跳转向性能和整车动态转向特性的影响。通过对多款前麦弗逊车型稳定杆吊杆等效转向力臂值的统计分析,给出合理等效转向力臂值,为指导后期的悬架稳定杆吊杆硬点设计提供了有效依据。
