轮毂轴承维持着汽车行驶的重任，承担着降低底盘运转时的摩擦阻力，日常维护肯定是必不可少的，下面
济南哪里修奥迪比较专业厂家来讲讲汽车的轮毂轴承在拆卸时的正确步骤！
The wheel hub bearing maintains the heavy task of driving the car, and is responsible for reducing the friction resistance when the chassis is running. Daily maintenance must be essential. Next, where to repair Audi in Jinan, a professional manufacturer, will talk about the correct steps for removing the wheel hub bearing of the car!
1、拆下轮毂轴头的装饰盖、防尘罩；
1. Remove the decorative cover and dust cover of the hub shaft head;
2、拆下轮胎但不要碰伤轮胎螺栓的螺纹，如果是盘式制动器，应拆下制动器，再用工具拆下锁圈或锁销。
2. Remove the tire without damaging the thread of the tire bolt. If it is a disc brake, remove the brake, and then remove the lock ring or lock pin with a tool.
3、使用专用的工具拆下轮毂轴承；
3. Use special tools to remove the hub bearing;
4、清理旧的润滑脂，并使用清洁剂清洗然后用抹布擦干，后用布擦净轴承内腔。
4. Clean the old grease, clean it with detergent, dry it with a rag, and then clean the bearing cavity with a cloth.
5、检查轮毂轴承与轴承座圈，发现有裂纹、疲劳剥落和轴承滚子松散等现象，应更换轴承。如果发现轴承座圈上有麻点，也应更换轴承。
5. Check the hub bearing and bearing race. If cracks, fatigue peeling and loose bearing rollers are found, replace the bearing. If any pitting is found on the bearing race, the bearing should also be replaced.
6、检查轴承内径与轴颈的配合情况，配合间隙应不大于0.10mm测量轴颈时，应在垂直地面的上下两个部位（该处为大的磨损部位）测量。如果配合间隙超过规定的使用限度，应更换轴承，使之恢复正常的配合间隙。不允许在轴颈上打毛刺、麻点来缩小间隙。
6. Check the fit between the bearing inner diameter and the journal. The fit clearance should not be greater than 0.10mm. When measuring the journal, it should be measured at the upper and lower parts of the vertical ground (this is a large wear part). If the fit clearance exceeds the specified service limit, replace the bearing to restore the normal fit clearance. Burrs and pits are not allowed on the journal to reduce the clearance.
7、待所有零件都符合要求后，就能将涂有润滑脂的内轴放入到轮毂中。
7. After all parts meet the requirements, the inner shaft coated with grease can be put into the hub.
8、在涂抹润滑脂的时候也要注意，涂抹的量也有要求，它需要你从轴承一端涂抹到轴承的另一边，直到它冒出来为止，不过，腔内不要涂抹太多。
8. Pay attention to the amount of grease when applying it. It requires you to apply it from one end of the bearing to the other until it emerges. However, do not apply too much grease in the cavity.
9、把轮毂和外轴都重新装到轴径上面，用手将轴头调整螺母拧上，然后用轴头扳手按规定扭力拧紧调整螺母。拧紧螺母后，应左右转动轮毂几圈，看看轴承安装情况；另一方面，通过转动使轴承与座圈正确配合。此时轴承紧度适当，车轮自由转动而感觉不出轴向间隙。
9. Reinstall the hub and the outer shaft onto the shaft diameter, screw on the shaft head adjusting nut by hand, and then use the shaft head wrench to tighten the adjusting nut according to the specified torque. After tightening the nut, rotate the hub left and right for several turns to check the installation of the bearing; On the other hand, rotate to make the bearing fit correctly with the race. At this time, the bearing tightness is appropriate, and the wheel rotates freely without axial clearance.
10、后依次安装锁片、固定螺母、轮胎、防尘罩和装饰盖等零件。
10. After that, install lock plate, fixing nut, tire, dust cover, decorative cover and other parts in turn.
11、轮毂轴承调整好后，行驶一段里程（10km左右），停车检查，用手拭摸轮毂的温度，如果发热，为轴承调整过紧所致，应重新调整，适当放松轴承紧度。
11. After the wheel hub bearing is adjusted, drive for a certain mileage (about 10km), stop to check, and touch the temperature of the wheel hub with your hand. If the heating is caused by the too tight adjustment of the bearing, readjust it, and properly loosen the bearing tightness.
In addition, car maintenance is a continuous task, and good maintenance at ordinary times plays a great role in safe driving, so the majority of car owners should pay more attention to the daily maintenance of cars! More relevant content will come to our website http://www.lutongqixiu.com Consult!
