What Is a Shock Absorber?

Absorber is used to suppress the shock and impact from the road when the spring rebounds after shock absorption. Widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the ride comfort of automobiles. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will have a reciprocating motion, and the shock absorber is used to restrain this spring from jumping. ^[1]

In order to accelerate the attenuation of frame and body vibration,

First, check whether the product provides a 2-3 inch lift requirement. Some products only provide a 2 inch lift. After barely using the 3 inch lift, it is easy to pull to the limit and cause damage in off-road.

Second, whether the diameter of the center telescopic rod of the shock absorber can reach more than 16 mm, which is a basic indicator of strength.

Third, whether the upper and lower connection sleeves of the shock absorber are high-strength polyurethane sleeves, which is also an important basis for ensuring long-term high-strength use, because ordinary rubber is difficult to use for a long time under high strength.

The shock absorber is mainly used to suppress the shock when the spring rebounds after shock absorption and the impact from the road. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will have a reciprocating motion, and the shock absorber is used to restrain this spring from jumping. If the shock absorber is too soft, the body will jump up and down, and if the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. Shi Xiaohui said that on

If a car shock absorber leaks oil, it is undoubtedly a very dangerous thing for the shock absorber. Well, once

In order to quickly attenuate the vibration of the frame and the body, and improve the ride comfort and comfort of the car, shock absorbers are generally installed on the suspension system of the car, and the two-way cylinder shock absorbers are widely used in automobiles.

Shock absorber is a fragile accessory during the use of the car. The work of the shock absorber will directly affect the smoothness of the car and the life of other parts. Therefore, we should make the shock absorber always in good working condition. The following methods can be used to check whether the shock absorber works well.

1. Make the car stop after driving for 10km on the road with poor road conditions, and touch the shock absorber shell with your 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, you can add an appropriate lubricant, and then perform the test. If the shell is hot, there is a lack of oil in the shock absorber. You should add enough oil, otherwise the shock absorber is invalid.

2. Press the bumper firmly and release it. If the car has 2 or 3 jumps, the shock absorber is working well.

3. When the car is driving slowly and emergency braking, if the car vibrates violently, it indicates that the shock absorber is defective.

4. Remove the shock absorber to stand it upright, clamp the lower end connection ring to the vise, and pull the damping rod several times. At this time, there should be a stable resistance. The resistance to pull up should be greater than that when pressed down. The resistance, such as unstable or non-resistance, may be due to lack of oil inside the shock absorber or damage to valve parts. Repair or replace parts.

After determining that there is a problem or failure of the shock absorber, you should first check whether the shock absorber is leaking oil or there are signs of old oil leakage.

If there is no oil leakage from the shock absorber, inspect the bushings for damage, desoldering, cracking or falling off. If the above inspection is normal, the shock absorber should be further disassembled, check whether the fit clearance between the piston and the cylinder is too large, whether the cylinder is damaged, whether the valve seal is good, whether the valve disc and the valve seat are tightly attached, Check whether the extension spring of the shock absorber is too soft or broken.

Auto parts manufacturers are becoming a globalized trend, leaving the auto companies and forming specialized parts groups. Almost all of the world-renowned automobile and parts companies have established joint ventures or wholly-owned enterprises in China, and more than 1,000 joint ventures have introduced technology. A number of domestic high-tech, good-efficiency, large-scale automobile and component companies have gradually grown. As the international automotive industry begins to implement the "global procurement" strategy for parts and components and the localization strategy of international multinational automobile companies, a huge gap in parts and accessories will appear in the domestic market. By 2010, the domestic output value of China's auto parts will reach about 700 billion yuan. The production prospect is broad and the appreciation space is huge.
