1.吃胎 简单的说就是有一个或者几个轮胎内侧或者外侧不正常的加速磨损 比起另外几个轮胎 某一个胎的某个部分磨损的特别快， 可以在检查轮胎的时候 明显的看出来花纹下的别别的胎或者同一个胎的另外部分下的深 很快造成偏磨 导致该轮胎报废。
2.什么原因造成的呢 一般来说 有这样几个原因
a.四轮定位不准确 造成四个轮胎不是在标准要求的横竖两条直线上 那么同侧的2个轮子在跑起来的时候就会发生吃胎现象 或者前轮或者后轮 主要是不走直线了 车辆自行矫正 造成某个轮胎的某个部位对地摩擦力不正常加大 加速磨损。 我说的有点不清楚 没想好怎么表达 总之吧 你想像一下 一个车的四个轮子应在一个长方形的四个定点的位置 如果不是 那么跑起来就会较劲 就会造成轮胎磨损。
b.前束调节不准确 也会造成吃胎 前束是什么呢 就是前轮向内侧稍稍倾斜的一个角度 类似内八字 这是高速稳定行车的最佳角度 所有的车都有一个自己的前束角 这个角度没调整好也会吃胎 道理同第一条
c.方向机故障 也会造成吃胎 跑偏等
d.大梁不平整 失型 也会造成吃胎 比如有些事故车 吃胎的原因就是大梁车身变形了
e.各个轮胎的气压差异太大 也会吃胎 不同规格的轮胎混装 也会吃胎 道理都是一样的 就是四只脚不和谐了 不在一个顺畅的环境干活了 就会吃胎 因为吃别的吃不动 哈哈哈哈
主要原因差不多就这些把
3.如何解决呢 大梁变形的 没办法 只能去校正 其它的都自己看着办吧 不难 绝大多数吃胎都可以用调前束和四轮定位的办法矫正
