減震器故障常見的檢查方法Common inspection methods of shock absorber failuRE

很多人知道汽車減震器的作用，可是很多人卻不知道汽車減震器的檢查該怎樣進行，工作正常的汽車減震器，可以緩解路面給汽車帶來的衝擊，迅速吸收顛簸時產生的震動，使車輛恢複到正常行駛狀態；而不正常的汽車減震器會有什麼樣反應呢? 

Many people know the function of the automobile shock absorber, but many people don't know how to check the automobile shock absorber. The normal automobile shock absorber can alleviate the impact brought by the road surfACE, quickly absorb the vibration generated by bumps, and make the vehicle return to normal driving state. What kind of reaction will the abnormal automobile shock absorber have?

　　用力按下保險杠，然後鬆開，如果汽車有2~3次跳躍，則說明減震器工作良好，反之則就是工作不是很正常。拆下減震器將其直立，並把下端連接環夾於台鉗上，用力拉壓減振杆數次，此時應有穩定的阻力，往上拉的阻力應大於向下壓時的阻力，如阻力不穩定或無阻力，可能是減震器內部缺油或閥門零件損壞，應進行修複或更換零件。使汽車在道路條件較差的路面上行駛10km後停車，用手摸減震器外殼，如果不夠熱，說明減震器內部無阻力，減震器不工作。此時，可加入適當的潤滑油，再進行試驗，若外殼發熱，則為減震器內部缺油，應加足油；否則，說明減震器失效。 

Press down the bumper and release it. If the car jumps for 2-3 times, it means that the shock absorber is working well, otherwise, it is not working normally. Remove the shock absorber, put it upright, clamp the lower connecting ring on the vise, and pull and press the shock absorber rod several times. At this time, there should be stable resistance, and the resistance of upward pulling should be greater than that of downward pressure. If the resistance is unstable or no resistance, it may be the lack of oil in the shock absorber or the valve parts are damaged. Repair or replace the parts. Make the car stop after driving for 10km on the road with poor road conditions. Touch the shock absorber shell by hand. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, appropriate lubricating oil can be added, and then the test is conducted. If the shell is heated, the shock absorber is short of oil, and sufficient oil should be added; otherwise, the shock absorber is invalid.

　　***，減震器在實際使用中會有發出響聲的故障，這主要是由於減震器與鋼板彈簧、車架或軸相碰撞而產生的，膠墊損壞或脫落以及減震器防塵筒變形，油液不足等原因引起的，應查明原因，予以修理。減震器的正常工作可以保證我們在駕車的過程中更多的平穩前進，所以要及時檢查減震器的工作是否正常。

Finally, the shock absorber will make noise in actual use, which is mainly caused by the collision between the shock absorber and leaf spring, frame or shaft, damage or fall off of rubber pad, deformation of shock absorber dust cylinder and insufficient oil. The causes should be found out and repaired. The normal work of the shock absorber can ensure that we drive more smoothly in the process of driving, so we should timely check whether the shock absorber works normally.
