The shock absorber of a car is used for shock absorption. In ancient times, there was no shock absorber when the carriage swayed. Many people think that shock absorbers exist only to support the weight of the car body. However, this is not the case. The shock absorber only absorbs the vibration and the impact force from the road surface, and inhibits the vibration of the spring rebound. If you drive a car with a broken shock absorber, you will feel the bumps caused by the ups and downs when the car passes through every pothole, and the shock absorber is designed to filter this bounce. Next, let's take a look at the deformation of Bian Xiao automobile shock absorber in the electric state.
Automobile shock absorber tower will deform-brief introduction of shock absorber tower, which is the full name of vehicle shock absorber seat, translated by Hong Kong and Taiwan as the top of the tower, plays the role of installing, fixing and supporting shock absorber, and can also be used as the fulcrum for installing the ejector rod of car body reinforcement when necessary.
The metal tower top refers to the part where the upper end of the shock absorber is connected with the frame, and the metal material is used to replace the hard rubber tower top for connection. Because soft rubber can absorb vibration and improve comfort, but it will make the transmission of force indirect, some manufacturers who modify shock absorbers have developed metal tower tops. It can make up for the problem that the vibration absorption of the hard rubber tower top affects the transmission, and the sense of giving way is more direct and the control is also helpful. However, due to the direct transmission of metal, some vibrations that would have been filtered out will also be transmitted to the carriage. At the same time, there is no soft medium to absorb subtle vibration, and the metal tower top is prone to noise.
Automobile shock absorber tower will be deformed-whether the shock absorber works well or not is a vulnerable part in the process of automobile use. The working condition of the shock absorber will directly affect the stability of the car and the life of other parts, so we should always keep the shock absorber in good working condition. You can check whether the shock absorber works well in the following ways.
1. Drive on the road with bad road conditions 10km, then stop and touch the shell of the shock absorber with your hands. 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 can be carried out. If the shell is hot, it is the lack of oil inside the shock absorber, so it is necessary to add enough oil; Otherwise, the shock absorber is invalid.
2. Press the bumper hard and release it. If the car jumps 2~3 times, the shock absorber works well.
3. When the car is driving slowly and braking urgently, if the car vibrates violently, there is something wrong with the shock absorber.
4. Remove the shock absorber and stand upright, clamp the lower connecting ring on a vise, and press the shock absorber rod hard for several times. At this time, there should be stable resistance, and the resistance of pulling up (restoring) is greater than the resistance of pressing down. If the resistance is unstable or there is no resistance, it may be that the shock absorber is short of oil or the valve element is damaged, so the parts should be repaired or replaced.
After determining that there is a problem or fault with the shock absorber, first check whether the shock absorber leaks oil or has traces of old oil leakage. The oil seal gasket and gasket are damaged, and the oil tank cover nut is loose. It may be that the oil seal and sealing washer are damaged and failed, so a new seal should be replaced. If the oil leakage still cannot be eliminated, pull out the shock absorber. If you feel that there is a hairpin or the weight is different, further check whether the gap between the piston and the cylinder is too large, whether the piston connecting rod of the shock absorber is bent, and whether the surfaces of the piston connecting rod and the cylinder are scratched or scraped.
