The most intuitive manifestation of a broken car shock absorber is the weakening of the shock absorption effect. When we pass some rugged roads, the car will make abnormal noises. What's more, it will affect the suspension, and then our The car will be repaired. In fact, many friends don't care too much about the broken shock absorber.
But when the oil leakage of the shock absorber reaches a certain limit, the role of the shock absorber no longer exists. In fact, it has a great impact on the car chassis. To be honest, the role of the shock absorber is to maintain the car. Comfort and safety, if the shock absorber is damaged, the probability of road accidents will increase.
In severe cases, this will cause the axle to break and the car to roll over. The most common failure of the shock absorber is oil leakage. If the shock absorber leaks, it will cause the internal hydraulic system pressure to be unbalanced and the shock absorption effect will be reduced. Or disappear, the shock absorber cannot limit the frequency of spring impact, causing the frequency and amplitude of the shock absorber spring to be too fast and too large when the vehicle is running.
If it is a shock absorber with serious oil leakage, we can't feel it on normal roads, but we can feel it in potholes. If both are serious oil leakage, you will feel The shaking is obviously larger than that without oil leakage before. Another common fault of
shock absorbers is abnormal noise. There are two kinds of abnormal noise. This is always the abnormal noise inside the shock absorber itself, and the other is the abnormal noise of the top rubber of the shock absorber. The failure phenomena shown by the two are also different, which need to be kept in mind.
The abnormal noise inside the shock absorber is mainly manifested as the drum sound, which is the hydraulic knocking sound caused by the wear of the hydraulic components and seals inside the shock absorber. It is relatively dull, a bit like a shock absorber. If the shock absorber is too Soft, it cannot quickly absorb the vibration of the spring, the body jumps up and down, the grip of the tires and the ground is not good, but the comfort of the car is better.
And the overall family cars tend to use relatively soft shock absorbers. If the shock absorber is too hard, it will bring too much resistance and hinder the cushioning effect of the spring, but the tires and the ground have better grip, so Some sports cars or SUVs have very hard damping. Cars are generally equipped with 4 shock absorbers. If the shock absorber is damaged, generally visually check whether it is leaking.
The shock absorber is related to the comfort and safety of the car. If it is damaged at high speed, the consequences will be serious. The speed is too high, causing the car to overturn and the bridge to break. This is all possible. It is not one-sided. If the shock absorber is broken, it is best to replace it with a pair, and the left and right shock absorbers are replaced together to keep the car balanced. When driving, the left and right sides of the vehicle are unbalanced.
affects driving safety. If the shock absorber is broken and not replaced, it will reduce the shock absorption effect of the vehicle, causing the vehicle to vibrate too fast or too much, especially when the vehicle passes through a bumpy road, the impact speed is more obvious, Affect the grip of the tires, causing accidental traffic accidents.
In addition, if you ignore it for a long time, it may damage the suspension components of the vehicle. Now you need to go to a professional repair shop for repair. The shock absorber is related to the comfort and safety of the vehicle during driving. When driving at high speed on the road, the vehicle speed is too high, which may cause the vehicle to roll over.
At the same time, the fuel consumption of the vehicle increases and the tire wear phenomenon brings danger to driving. If the temperature of the shock absorber body is not high enough, it means that there is no resistance inside the shock absorber and the shock absorber can no longer work normally. Grease restart the test.
