减震器故障常见的检查方法Common inspection methods of shock absorber failuRE

很多人知道汽车减震器的作用，可是很多人却不知道汽车减震器的检查该怎样进行，工作正常的汽车减震器，可以缓解路面给汽车带来的冲击，迅速吸收颠簸时产生的震动，使车辆恢复到正常行驶状态；而不正常的汽车减震器会有什么样反应呢? 

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?

　　用力按下保险杠，然后松开，如果汽车有2~3次跳跃，则说明减震器工作良好，反之则就是工作不是很正常。拆下减震器将其直立，并把下端连接环夹于台钳上，用力拉压减振杆数次，此时应有稳定的阻力，往上拉的阻力应大于向下压时的阻力，如阻力不稳定或无阻力，可能是减震器内部缺油或阀门零件损坏，应进行修复或更换零件。使汽车在道路条件较差的路面上行驶10km后停车，用手摸减震器外壳，如果不够热，说明减震器内部无阻力，减震器不工作。此时，可加入适当的润滑油，再进行试验，若外壳发热，则为减震器内部缺油，应加足油；否则，说明减震器失效。 

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.

　　***，减震器在实际使用中会有发出响声的故障，这主要是由于减震器与钢板弹簧、车架或轴相碰撞而产生的，胶垫损坏或脱落以及减震器防尘筒变形，油液不足等原因引起的，应查明原因，予以修理。减震器的正常工作可以保证我们在驾车的过程中更多的平稳前进，所以要及时检查减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.
