In order to quickly decay the vibration of the frame and the body, and improve the smoothness and comfort of the vehicle driving, the car suspension system is generally equipped with a shock absorber. The shock absorber is a damaged accessory during the use of the car.The good or bad work will directly affect the smoothness of the car and the life of other machines, so we should make the shock absorber often in a good working state.Let ’s take a look at the Encyclopedia of the shock absorber.
The role of a car shock absorber
When the spring is impacted by the car surface, it will absorb the vibration force by compressing and deformation by itself, which can buffer the bumpy vibration of the body and cause bumps.Then, when the impact force disappears, the spring will restore the original state, and at the same time release the absorption energy, stretch and deform itself, so as to play the car upwards. This phenomenon becomes a rebound.The rebound will make the passengers feel uncomfortable in the car, and it will make it difficult to control in the car, and it is prone to danger.
Since the discovery of the spring cannot stabilize the car body, the car designers have installed the shock absorber in the suspension to prevent the rebound of rebound.If there is a shock absorber in the suspension, the situation is like a tram used by hawkers, and the body will continue to shake.The role of spring is to buffer the impact of the pavement, but the role of the shock absorber is to limit the excessive elasticity of the spring, and the role of the two is completely different.It is with their coordination that cars can drive so smoothly and have a more comfortable driving experience.
How to maintain a car shock absorber
1. Park the car in a flat place
When parking, try to parry the car on a relatively flat ground. Do not let the vehicle parked for a long time.
2. Slowly walk slowly
There are deceleration bands in some schools, steep slopes and other places. The vehicles should be decelerated in advance, otherwise not only will increase the danger, but also the speed of vehicle shock absorption will be damaged.
3. Avoid pulling heavy objects for a long time
If you often use overweight things or passengers, overloading will cause shock absorbers to overload, affect elasticity, easily damage the shock absorber, and will not be accurately reset like before.
4. Survival killer road lid
Pass through it.Sometimes you may borrow a little lane next to it (when there are not many cars on the road).How novices judge can let the car pass through.Dont let any of the four wheels go up one by one.The easiest way.The right foot on the accelerator.The center point of the knee -to -knee manhole cover or a large pit.
5. Avoid putting heavy objects in the trunk for a long time
Generally, the four -wheel shock absorbers have been adjusted to the best state. When the trunk is placed heavier for a long time, the rear wheel shock absorption is severely pressured, and the oil sealing force increases, resulting in the possibility of oil leakage.
6. Check the shock absorber regularly
Under normal circumstances, a shock absorber should be checked every 20,000 kilometers to check whether the shock absorber is oil leakage and failure.Press the bumper hard during the inspection, and then release it. If the car jumps 2 to 3 times, it means that the shock absorber is good.
System maintenance of car shock absorber
1. Regularly check the performance of the shock absorber
1. First press the bumper hard and release, and then release it. If the car jumps 2 to 3 times, it means that the shock absorbers work well.Once there is a problem with the shock absorber, it is best not to adjust it yourself. In case of problems, the consequences are also very serious.
2. Another simple detection method is that the car is driving slowly, and then emergency braking. If the vibration of the car is more severe, it means that the car shock absorber has a certain problem.
2. Add regular lubricating oil
In many cases, the amount of lubricating oil inside the shock absorber is greatly reduced, resulting in the performance of the shock absorber will be greatly affected.Therefore, the owner should add lubricating oil regularly to a large extent to ensure the normal work of the shock absorber.Many shock absorbers will leak oil on the surface with the growth of use time, which will also have a great impact on the life of the shock absorbers and need to be repaired as soon as possible.
Third, performance test
After repairing the shock absorber, the performance of the shock absorber should be tested to determine that there is no problem with the performance of the shock absorber. When the resistance frequency is 100 ± 1mm, the resistance of the extension and compression strokes should meet the requirements.It shows that the shock absorber is basically normal.
Shock absorption oil maintenance is important
1. When storing and use, the container and refueling tools must be cleaned and tightly prevent mixed water impurities to avoid additive sedimentation and oil -based deterioration.
2. During the use, if there is no leakage of the shock absorber, every 40,000 to 50,000 km is maintained regularly, the shock absorbers are dismantled, and the shock absorber oil is replaced at the same time according to the specified quantity.
3. When lacking shock absorber oil, it can be used for HV15 low -temperature hydraulic oil.
Therefore, when saving shock absorption oil, store it in a place where the sunlight is directly shined to avoid the deterioration of the shock absorption oil.When the shock absorption oil is found insufficient, you can use the HV15 low -temperature hydraulic oil to replace the shock absorption oil.
