在汽车行驶的过程中，难免会转弯，这就依靠于汽车的转向系统喽，在二手车估价的过程中，转向系统的检测也是尤为重要，占影响车辆价格的比重也是较大的，一旦转向系统受损，那么这个二手车的价格会大大的降低。接下来就让小编谈一谈转向系统的那些事吧。

转向系统主要是由转向操纵机构（转向盘，转向轴，转向管柱），转向器，转向传动机构组成；主要作用是通过汽车驾驶员操作根据需要改变汽车的行驶方向；目前的分类主要由机械转向系统和动力转向系统。

二手车评估过程中，转向系统该如何去检测呢？

以下便是在二手车评估时经常遇到的转向系统故障，以及故障原因

1. 方向跑偏

两只前轮轮胎气压不同；两只前轮的注销后倾角不等；前束超差左右前轮轮毂轴承调整间隙不一致；一边车轮制动卡滞。

2. 转向沉重

转向管路，转向叶片泵故障；动力转向器故障；转动传动机构故障，前轮定位参数不准；轮胎气压过低；前轮轴承咬死，配合过紧。

3. 转向不灵敏，操纵不稳定

转向器安装松动；动力转向器齿轮齿条啮合间隙变大；左右横拉杆球头销磨损松动；转向柱与方向盘连接的三角花键配合间隙过大或锁紧螺母松动；车轴轴承间隙过大

4. 高速摆动

前轮胎动平衡不对；转向传动部件安装松动；转向盘自由行程过大；转向器滚轮与蜗杆啮合间隙过大；蜗杆上下轴承间隙过大；转向节主销与衬套的间隙过大；前轮轮壳轴承装配过松，或前轮轮辋失圆摆差过大；前轮定位失准。

二手车评估过程中，转向系统该如何去检测呢？

 以上基本上算是转向系统最容易发生的故障了。而且每一个故障都会大大的影响到二手车的评估价格，想了解更多的二手车技巧以及二手车评估案例就来关注一下吧。
