诊断和更换车轮轴承

诊断一个磨损的轮毂轴承可能很棘手。 许多磨损的轮毂轴承会发出噪音

改变悬架的几何形状,你就改变了车轮轴承的负荷因素。

当出现噪音时,轴承可以发出任何这些声音:

- 在高速路上发出嗡嗡声。

- 磨削噪音

- 敲击声

- 咆哮的声音

然而,磨损的悬架部件和轮胎也会发出同样的声音。 因此,你的工作是隔离噪音。 一种方法是在笔直的平坦道路上驾驶车辆,建立一个基线噪音。 然后稍微转动车辆(就像你在改变车道),看看噪音是否改变。 另外,增加和减少速度,看看噪音是否随速度变化。

检查轮毂轴承的游隙

大多数车轮轴承在发展到足以在车轮上感觉到游隙之前就开始发出噪音。 当它们磨损到这种程度时,你有时可以感觉到方向盘的振动,并注意到汽车无法保持直线行驶。 有时,车轮轴承过度磨损会导致ABS轮速传感器的问题,你会得到一个间歇性的ABS故障灯,由于掉了轮速传感器的信号。

用汽车听诊器检查车轮轴承

将车辆放在千斤顶架上,通过以下方式旋转车轮 如果你听到噪音,使用汽车听诊器找到噪音的位置。 将听诊器探针触及转向节。 阅读这篇关于如何使用汽车听诊器的文章

检查车轮轴承是否有间隙

在2点和6点位置抓住轮胎,拉动和推动以检测轮毂运动。 不要将橡胶运动与轮毂运动混淆。

将手放在12点和6点位置,摇动车轮进出,检查车轮轴承。

然后将你的手移到3点和6点的位置,重复。

然后在3点和9点试着摇一摇

检查轮毂轴承密封是否泄漏

许多轮毂轴承是永久密封的。 但如果密封恶化,润滑脂就会渗漏出来。 所以要检查轴承是否有润滑脂渗漏的迹象。 有密封的轮毂轴承不应该有渗漏的迹象。 如果有,就是坏的。 任何渗漏润滑脂的密封,也是允许水进入轴承的。

如何更换磨损的车轮轴承

如果轮毂轴承是一个单元轴承组件,你必须更换整个单元。 卸下车桥螺母(在前轮驱动车辆上),然后 卸下轮毂的固定螺栓,你

轮毂轴承总成

可能要把旧的装置从关节处撬出来。

如果车轮轴承被压入转向节,你必须租用适当的工具(如轮毂钳)将其拆下,或将整个转向节拆下,送到机械厂,付钱给他们换出轴承。

拧紧车轴螺母

在重新组装新轴承时,你可能犯的最大错误是使用冲击扳手来拧紧轴螺母。 快速的冲击会使滚子或球轴承上的镀铬层脱落,并可能损坏内部滚道。 你不会马上注意到这种损坏,但由于你的冲击造成的损坏,轴承会提前失效。扳手。

因此,用棘轮扳手和套筒用手拧紧车轴螺母,使螺母就位。 然后用扭矩扳手按照规格设置预紧力。 不使用扭矩扳手会导致轴承过早失效!适当的预紧力至关重要!如果预紧力低于规格,轴承会分离。
