某载货车转向回正性差的分析及优化

Analysis and optimization of poor steering reversal of a truck

文章根据某载货车转向回正性试验测试结果,对转向回正性差的问题进行了问题原因的分析,在诸多因素中找出了前桥阻滞力矩大、主销后倾角小两个主要问题原因,制定针对性的优化设计方案。问题整改完成后进一步进行试验验证,验证结果达到了满意的效果。

In this paper, the problem that truck actual is bad was analyzed according tothe actual parameters of a truck. Two reasons that the retardation torque of the front axle is large and the caster angle is small were qualified from a lot of factors. They may have a main effect on the experiment parameters. Formulate a scheme combined these reasons. After modified, the experiment was verifiedagain. The verification result has a great effect.
