一般情况下,汽车底盘出现异响时,很多都是下支臂球头、下支臂胶套或者是稳定杆小连杆等零件出现了问题,需要维修。而师傅的维修办法基本也都是换整根新下支臂,很少会单独更换球头。
师傅介绍,这主要是因为下支臂球头与下支臂合金材质的设计是一个整体,球头只要坏了,必须换整根下支臂才行,只有很少的车型,由于设计等原因,可以单独更换球头或胶套,维修成本降低很多。
这不,一辆奥迪A6L因为底盘下支臂球头出现异响,师傅更换了整根下支臂才解决问题。看着换下来的两根下支臂,车主表示,换整根下支臂有点不合理!不过,这也没办法,只有这样维修!下图所示,它的行驶里程已经超过了16万公里!
奥迪车主描述的故障现象是:行驶在颠簸路面,底盘总会咕咚响。师傅发现是弯下支臂的球头损坏,而球头不能单独更换,需要更换整根弯下支臂才行。车主无奈同意更换。
师傅先是把下支臂与副车架固定胶套的螺丝拆下,然后把固定球头的螺丝拆下,但是球头还在转向节里面卡着,很难拆下。下图绿色箭头所示,这就是拆球头的专用工具。如果没有专用工具,用铁锤使劲砸橙色箭头的位置,也可以取出球头。
师傅用了半个小时才把左右弯下支臂给拆了下来,如下图所示。橙色区域所示,这是下支臂的胶套,轻微损坏;绿色区域所示,这是下支臂球头。虽然球头胶套没有破损,但是内部已经损坏,车主上次换的下支臂质量比较差。注意红色箭头所示,转向节上的铁套被球头带了下来,和上一篇文章中的情况一样。
下图绿色区域所示,上图中球头卡着的铁套应该在它里面安装。接下来,师傅需要想办法把上图中的铁套给取下。
为了看得更清楚,小编又拍了一张图,如下图箭头所示,一下就能看出区别,汽修师傅正试着用工具拆下球头的铁套。
师傅用下图所示的办法拆了很多次,也没能把这个铁套给拆下来,卡得实在是太牢固了! 反正这个球头已经坏了不用,师傅用压力机才把这个铁套给拆了下来。
下支臂球头铁套被取下后,师傅很快就把新下支臂给安装到底盘,只是橙色箭头所示的这个胶套螺丝没有紧固,需要用拖板车顶起来才能紧固!
绿色箭头所示,师傅用拖板车顶起下支臂球头位置,模拟底盘受力,然后紧固橙色箭头所示的胶套螺丝。这样的话,汽车在平路时,这个胶套不受力,当汽车在颠簸路面时,下支臂上下运动时,这个支臂胶套受力,延长支臂的使用寿命。若是不这样操作的话,支臂胶套很容易就会损坏!
最后,师傅试车,行驶在颠簸路面时,底盘已经不会出现异响!车主对于维修结果很是满意,只是看着换下来的下支臂,车主还感觉有点可惜,若是能单独更换支臂球头就能省很多钱。
