The inspection of the shock absorber of the automobile shock absorber, how to detect the shock absor

1. Make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell 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, you can add appropriate lubricating oil, and then test, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber has failed.

2 Press the bumper firmly and then release, if the car has 2 3 jumps, then the shock absorber is working well.

3 When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

4. Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, pull and press the damping rod several times, at this time there should be a stable resistance, the resistance to pull up (restoration) should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

Hello! The detection method of automobile shock absorber is as follows:

Make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell 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, you can add appropriate lubricating oil, and then try this test, if the shell is hot, it is a lack of oil inside the shock absorber, and enough oil should be added; Otherwise, the shock absorber has failed; Press the bumper hard, then release, if the car has 2 or 3 jumps, then the shock absorber is working well; When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber; Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, and pull and press the damping rod several times, at this time there should be stable resistance, and the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

After determining that the shock absorber is faulty or failing, you should first check the shock absorber for oil leakage or signs of old oil leakage.

The oil seal gasket and sealing washer are broken and damaged, and the oil storage cylinder head nut is loose. It may be that the oil seal and sealing gasket are damaged and failed, and the new seal should be replaced. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out, if you feel a hairpin or a difference in weight, further check whether the gap between the piston and the cylinder barrel is too large, whether the piston connecting rod of the shock absorber is bent, and whether the piston connecting rod surface and the cylinder barrel are scratched or pulled marks.

If there is no oil leakage in the shock absorber, the shock absorber connecting pin, connecting rod, connecting hole, rubber, bushing, etc. should be checked for damage, desoldering, cracking or falling off. If the above inspection is normal, the shock absorber should be further decomposed, check whether the matching gap between the piston and the cylinder barrel is too large, whether the cylinder barrel is strained, whether the valve seal is good, whether the valve disc and the valve seat are tightly fitted, and whether the extension spring of the shock absorber is too soft or broken, and repair or replace the parts according to the situation.

In addition, the shock absorber will make a sound in the actual use of the fault, which is mainly due to the shock absorber and the leaf spring, frame or shaft collision, rubber pad damage or fall off, and the shock absorber dustproof car and barrel deformation, insufficient oil and other reasons, should be found out the reason, to be repaired.

When the resistance frequency is 100 1mm, the resistance of its extension stroke and compression stroke should meet the regulations, indicating that the shock absorber is basically normal.

Web decluttering. Automobile shock absorbers are used to accelerate the attenuation of frame and body vibration to improve the smoothness and comfort of car driving. Especially when driving on rugged mountain roads in the wilderness, the role of automobile shock absorbers is particularly prominent.

The failure or damage of the shock absorber will directly affect the driving smoothness and ride comfort of the car, and even affect the life of the car. Therefore, the inspection of automobile shock absorbers is very important, and car owners should always pay attention to the use of automobile shock absorbers, and deal with problems in a timely manner. Here are four ways to quickly test the performance of your car's shock absorbers.

If car owners find that the shock absorber makes a sound failure, it is mainly due to the collision between the shock absorber and the leaf spring, frame or axle, the damage or detachment of the rubber pad, the deformation of the shock absorber dust cylinder, and the lack of liquid and fluid.

1. Make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell 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, you can add appropriate lubricating oil, and then carry out the test, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber has failed;

Second, drive at a low speed, and then brake sharply, if you find that the car shakes more violently, and the human body feels uncomfortable, then there is a problem with the shock absorber. However, this method is best used sparingly, because frequent sudden braking can easily cause damage to the braking system.

3. Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, and pull and press the shock absorber bar several times, at this time there should be stable resistance, and the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

Fourth, press the bumper hard, and then release, if the car has 2 3 jumps, it means that the shock absorber is working well.

In addition, oil leakage is one of the reasons that causes the shock absorber to not work properly. If there is no oil leakage in the shock absorber, the shock absorber connecting pin, connecting rod, connecting hole, rubber, bushing, etc. should be checked for damage, desoldering, cracking or falling off. If the above inspection is normal, the shock absorber should be further decomposed, and whether the matching gap between the piston and the cylinder barrel is too large, whether the cylinder barrel is strained, whether the valve seal is good, whether the valve disc and the valve seat are tightly fitted, and whether the extension spring of the shock absorber is too soft or broken, and the method of grinding or replacement parts should be repaired according to the situation.

How are shock absorbers tested in cars? The main thing is to see if there is no oil leakage, other measurement methods are not particularly accurate, or go to the maintenance station to check the best However, as long as it is not a big bump, the shock absorber will generally not have problems within 100,000 kilometers Even if there is a problem, it is in the run-in stage of the new car After 1,000 kilometers, it is okay to use it with confidence It is not so easy to break In fact, the oil leakage is not that the shock absorber is completely unusable, but the shock absorber in the shock absorber is missing, resulting in the damping effect of the shock absorber becoming worse. The way to judge the failure of the shock absorber is to drive through the pothole, the road surface car can not quickly restore the stability is the failure, because it can not play a more real role, only the spring is working, the role of the shock absorber is to resist the spring when the spring is compressed, and pull the spring when the spring is stretched and long, so that the body posture can quickly return to stability.

There is a noise during driving, especially when the road is not good, the noise is loud and the car feels inflexible. Secondly, when the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber. Therefore, in the usual driving market, we should pay attention to road obstacles, and reduce the speed in time, and the speed bump in the city must be slowed down, which is particularly harmful to the shock absorption system of the vehicle.

Now the quality of domestic shock absorbers has been greatly improved, under normal circumstances, the regular manufacturer's products 5, 60,000 kilometers of life. Better products 8 to 100,000 km. Replacing the shock absorber is only one aspect measured in kilometers, the key is whether the driving feeling has deteriorated, if the new car feels obvious after a period of use, the comfort has deteriorated significantly, and the noise is obvious, it should be replaced.

Shock absorber testing includes shock absorber performance test, shock absorber durability test, and shock absorber dual excitation test. Indication tests, friction tests and temperature characteristics tests are carried out on various types of shock absorbers. After driving 10 km on a road with bad road conditions, stop the car and touch the housing of the shock absorber 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 point, the appropriate lubricating oil can be added and then the test can be carried out. If the shell is hot, it means that the shock absorber is short of oil, and it is necessary to add enough oil.

Otherwise, the shock absorber is ineffective. Press down firmly on the bumper, then release. If the car jumps 2 or 3 times, the shock absorber works well.

When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber. 4.Remove the shock absorber and erect it, clamp the lower connecting ring to the vice, pull and press the shock absorber rod sock brother several times.

At this time, there should be stable resistance, and the resistance to pull up (recovery) should be greater than the resistance to press down. If the resistance is unstable or there is no resistance, it may be that there is a lack of oil inside the shock absorber or the valve is damaged, and it should be repaired or replaced.

Millions of car purchase subsidies.

Shock absorber testing includes shock absorber performance test, shock absorber durability test, and shock absorber dual excitation test. Index, friction and temperature characteristics tests are carried out on various types of shock absorbers. Stop after driving 10km on a road with poor road conditions and touch the shock absorber housing with your hand.

If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber is not working. At this time, you can add appropriate lubricating oil and then carry out the test. If the shell is hot and the shock absorber is short of oil, it is necessary to add enough oil.

Otherwise, the shock absorber has no mountain stupidity. Press firmly on the bumper, then release. If the car jumps 2 or 3 times, the shock absorber works well.

When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber. 4.Remove the shock absorber and erect it, clip the lower connecting ring to the vice, pull and press the shock absorber lever a few times.

At this time, there should be stable resistance, and the resistance of pulling up (recovery) should be greater than pressing down. If the resistance is unstable or there is no resistance, it may be that there is a lack of oil inside the shock absorber or that the valve parts are damaged and should be repaired or replaced.

The first test method: make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell 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. When these acres are a few acres, you can add appropriate lubricating oil, and then carry out the test, if the shell is hot, it is the lack of oil inside the shock absorber, and the oil should be added; Otherwise, the shock absorber has failed;

The second test method: when the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

The third inspection method: press the safety Bitong bar hard, and then loosen it, if the car has 2 or 3 jumps, it means that the shock absorber is working well, on the contrary, you should go to the repair shop for inspection and repentance, to see the extent of its damage.

The fourth inspection method: remove the shock absorber to stand upright, and clamp the lower end of the connecting ring on the vice, pull and press the shock absorber rod several times, at this time there should be stable resistance, the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

The first point, the most direct way to judge, is to stop the car and check whether the shock absorber is leaking. If the shock absorber is damaged, there will be oil stains, but this does not mean that the shock absorber is damaged, and the shock absorber with oil stains can still be used, but because the oil in the shock absorber is not enough, the effect of the shock absorber becomes worse.

The second point is that when the car quickly passes through potholes or speed bumps, a tire bounces abnormally, accompanied by a rattling sound, indicating that the tire shock absorber has been damaged, and there is no way to achieve the effect of shock absorption, so there will be such a abnormal sound.

The third point is that when driving on a flat road, the body also swings from side to side. When we look at the rear car, it is obvious that the car in front will shake from side to side, indicating that the shock absorber has been damaged.

Fourth, the tires are abnormally worn. Abnormal tire wear, in addition to the tire pressure, may also be caused by damage to the shock absorber, resulting in abnormal tire wear.

Fifth, when the car stops, touch the shock absorber with your hand, if the shock absorber is warm, it means that the shock absorber is not damaged and is working normally. If the shock absorber is cold, it means that the shock absorber is not working and the shock absorber is damaged.

Sixth, press the four corners of the car hard and then quickly let go, if the four corners of the car are quickly **, and soon stop, it means that the shock absorber is in good condition. If there is a single corner vibration that only stops after many times, it means that the shock absorber is damaged.

Although the shock absorber is a wearing part on the car, it does not have a strict time standard and lead mileage standard, if the shock absorber is detected to be damaged, then replace it. In fact, the shock absorber can also be repaired, mainly because of the damage to the seals, such as the main parts of the cylinder, which are generally not damaged. If you can buy maintenance parts, then you can repair it, if you can't buy it, you can only replace the shock absorber assembly.

If the car vibrates more violently, then there is a problem with the shock absorber of the car. Or press the bumper of the car, and then release, if the car has 2 or 3 jumps, then it means that the working environment of the shock absorber is good, and there is no problem. Land collapse.

There is also the possibility of allowing the car to drive about 10 kilometers in poor road conditions and then stop. Then touch the shell of the shock absorber with your hands, if the feeling of the hand touching is warm, then it means that there is no resistance inside the shock absorber. At the same time, it also shows that the shock absorber is not working.

At this time, the owner can add some lubricating oil to lubricate.

The most intuitive way to identify the quality of a car's shock suspension is through driving. This is especially noticeable on uneven and undulating surfaces.

The most direct way is to remove it, press it and watch it bounce back. The rebound process is uniform and stable, rather than fast and slow, and there is no oil leakage and other phenomena in the shock absorber cylinder, and the shock absorber cylinder is good.

If the shock absorber cylinder is in good condition, then the air pressure shock absorber cylinder has much better performance than the oil pressure shock absorber cylinder, and it is also more durable.

If the shock absorber is intact, the comfort type depends on the tires and suspension.

Comfort tires with thick tires and control tires with thin tires with high tire pressure.

In winter and summer, the tire pressure increases and decreases as the temperature changes.
