【导读】
很多硬派越野或者皮卡车型,其承载能力较强、行驶路况恶劣,轮毂轴承多采用可维护类型。在日常养车中就十分考验车主的保养周期。如果置之不理,轮毂轴承的寿命将大大缩短。但常规的保养都是到维修店进行,少则1-200,多则4-500,大大提升了养车成本。其实这种可保养时轮毂轴承我们完全可以自己进行维护,下面几招学会了,让你轻松轻松省去几百元.
一、轮毂轴承的保养周期
1、依照轴承间隙
我们定期检查轮毂轴承的间隙,如果行驶了2-3万公里你发现轮胎出现了径向或者轴向间隙,就代表你的轴承出现了磨损消耗,需要保养了。
2、依照里程
一般来说,这种可维护的轴承,每3万公里拆卸进行清洗打油保养。
二、保养方法
多数的可拆卸轴承的拆卸方式都类似,学会以下步骤,基本可以应对市面上大多数可拆卸轴承的保养操作。
1、拆卸轮胎
2、打开防尘罩
防尘罩的拆卸要避免使用蛮力,禁止使用锤子使劲敲击,一旦防尘罩变形或者破损,将会导致行车时轴承进水。
3、拆卸连接法兰螺丝
4、拆卸卡簧
5、拆卸轴承挡板固定螺丝
6、取下轴承挡板
7、拆卸轮毂轴总成
从上图可以看到,当轴承拆卸以后,我们能够看到留在传动轴上的黄色固体,它是轴承进水导致生锈出现的杂质。
将轴承取出,我们能够看到,内部的润滑脂已经变质。并且有较为严重的锈蚀现象。这表明轴承已经超期服役,保养延后了。如果这种情况再继续行驶,将会导致轴承的磨损,也就没有保养的价值了。
8、油封的更换
保养之前我们要准备好相应的轴承油封,因为在拆卸轴承的时候是要拆卸油封的。而油封一旦拆卸就无法继续使用。
9、轴承的清洗
拆卸下来的轴承,我们查看其滚珠上面是否有比较严重的磨损,如果已经有比较严重的磨损就没必要保养了,只能更换解决。如果没有严重磨损,我们使用汽油将其表面沾染的润滑脂清理掉。
10、涂抹润滑脂
将准备好的润滑脂,均匀的涂抹在轴承的表面,并且用手挤压到轴承内部。
11、轴承的安装
这种可维护轴承,安装是比较简单的,无需任何压力机的辅助,直接放在轴承座上即可。
12、安装轴承油封
油封的安装要格外小心,尽量使用专用的油封安装器,如果没有的话。我们尽量使用与油封相同直径的金属扣碗,均匀的敲击进油封安装孔。
写在最后:
对于很多越野爱好者,车辆的轮毂轴承保养应该习以为常。但对于不经常越野的车主,而自己爱车还是这种可维护轴承,就要引起重视了。轴承的寿命完全依靠保养的频次,超期服役将影响轴承寿命。学会以上步骤,完全可以自己对轮毂轴承进行保养,省去几百元没有任何问题,你学会了吗?
