輪轂軸承維持著汽車行駛的重任，承擔(dān)著降低底盤運(yùn)轉(zhuǎn)時(shí)的摩擦阻力，日常維護(hù)肯定是必不可少的，下面濟(jì)南哪里修奧迪比較專業(yè)廠家來講講汽車的輪轂軸承在拆卸時(shí)的正確步驟！

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、拆下輪轂軸頭的裝飾蓋、防塵罩；

1. Remove the decorative cover and dust cover of the hub shaft head;

2、拆下輪胎但不要碰傷輪胎螺栓的螺紋，如果是盤式制動(dòng)器，應(yīng)拆下制動(dòng)器，再用工具拆下鎖圈或鎖銷。

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、使用專用的工具拆下輪轂軸承；

3. Use special tools to remove the hub bearing;

4、清理舊的潤(rùn)滑脂，并使用清潔劑清洗然后用抹布擦干，后用布擦凈軸承內(nèi)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、檢查輪轂軸承與軸承座圈，發(fā)現(xiàn)有裂紋、疲勞剝落和軸承滾子松散等現(xiàn)象，應(yīng)更換軸承。如果發(fā)現(xiàn)軸承座圈上有麻點(diǎn)，也應(yīng)更換軸承。

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、檢查軸承內(nèi)徑與軸頸的配合情況，配合間隙應(yīng)不大于0.10mm測(cè)量軸頸時(shí)，應(yīng)在垂直地面的上下兩個(gè)部位（該處為大的磨損部位）測(cè)量。如果配合間隙超過規(guī)定的使用限度，應(yīng)更換軸承，使之恢復(fù)正常的配合間隙。不允許在軸頸上打毛刺、麻點(diǎn)來縮小間隙。

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，就能將涂有潤(rùn)滑脂的內(nèi)軸放入到輪轂中。

7. After all parts meet the requirements, the inner shaft coated with grease can be put into the hub.

8、在涂抹潤(rùn)滑脂的時(shí)候也要注意，涂抹的量也有要求，它需要你從軸承一端涂抹到軸承的另一邊，直到它冒出來為止，不過，腔內(nèi)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、把輪轂和外軸都重新裝到軸徑上面，用手將軸頭調(diào)整螺母擰上，然后用軸頭扳手按規(guī)定扭力擰緊調(diào)整螺母。擰緊螺母后，應(yīng)左右轉(zhuǎn)動(dòng)輪轂幾圈，看看軸承安裝情況；另一方面，通過轉(zhuǎn)動(dòng)使軸承與座圈正確配合。此時(shí)軸承緊度適當(dāng)，車輪自由轉(zhuǎn)動(dòng)而感覺不出軸向間隙。

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、后依次安裝鎖片、固定螺母、輪胎、防塵罩和裝飾蓋等零件。

10. After that, install lock plate, fixing nut, tire, dust cover, decorative cover and other parts in turn.

11、輪轂軸承調(diào)整好后，行駛一段里程（10km左右），停車檢查，用手拭摸輪轂的溫度，如果發(fā)熱，為軸承調(diào)整過緊所致，應(yīng)重新調(diào)整，適當(dāng)放松軸承緊度。

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.

此外汽車保養(yǎng)是個(gè)持續(xù)性的活，平時(shí)保養(yǎng)做得好對(duì)安全駕駛起到很大的作用，所以廣大的車主們，還是要更加重視汽車的日常保養(yǎng)！更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.nhakhoathuduc.net進(jìn)行咨詢吧！
