What is a car shock absorber? What is its function?

1. The word vibration damper is a common term in the automobile chassis industry. Automobile vibration damper is actually a vibration damper. Vibration dampers are not only used in suspension in cars, but also in other positions. For example, it is used for cabs, seats, steering wheels, etc., and can also be used as a buffer on vehicle bumpers.

2. The car shock absorber is a vehicle accessory used to suppress the rebound impact after spring shock absorption, which can be used to improve the comfort during driving. The function of car shock absorbers. Roads with uneven roads or poor driving conditions will cause vehicles to shake and bump.

3. Automobile shock absorber is also called shock absorber, and its professional scientific name is "shock absorber damper": as the name implies, its function is to produce damping. It is one of the most important parts in the vehicle suspension system; the car suspension is composed of swing arm, elastic element and shock absorber damper.

4. The function of automobile shock absorbers is to suppress the vibration and the impact from the road surface when the spring rebounds after shock absorption.

5. The function of car shock absorber: bai shock absorber can make the vehicle run smoothly, and du shock absorber has the effect of buffering vibration. If there is no shock absorber in the suspension, the car will run unsteadily and will shake. Nowadays, the shock absorbers of many cars are hydraulic shock absorbers.

6. The main function of the shock absorber is to buffer vibration. It can make the car run smoothly, make passengers comfortable, and not easily feel bumps.The shock absorber is a part of the car suspension. After the impact brought by the ground reaches the spring, the shock absorber prevents the spring from rebounding to maintain the stable running of the car, otherwise the car is prone to body bumps.

What are the symptoms of a broken car shock absorber?

After the car shock absorber is damaged, the main manifestations are: oil leakage of the shock absorber, abnormal sound of the shock absorber, signs of side slippage, and poor shock absorption effect.Therefore, you should go to a professional auto repair shop or 4S in time to deal with it. Safe driving is the most important thing. Generally, after the shock absorber is damaged, there are the following faults: shock absorber oil leakage.

The performance of a broken car shock absorber is as follows: body shaking: For cars, the method of shaking the body can be used to judge the performance of the shock absorber. It can also be judged by the shaking state of the front and rear of the vehicle after emergency braking. After the vibration damper fails, the number of times the vehicle shakes is obviously more than normal.

The performance of the car's shock absorber is as follows: you can still feel the poor stability of the vehicle when the shock absorber is broken. If there is a slight unevenness on the road, the car will sway up and down. When crossing the upside-down road, it would have stopped if it was shaken up and down once or twice, but now it takes four times to stop, and the amplitude has become larger. This is a typical symptom of a broken shock absorber.

Common faults and overhaul of automobile shock absorbers

Common damage to hydraulic shock absorbers include oil leakage of shock absorbers, aging of rubber on the top of shock absorbers, fatigue softening of shock absorber springs, etc. Shock absorber oil leakage: When the vehicle is running, the shock absorption effect will be greatly reduced until the hydraulic oil leaks, and the vehicle has no shock absorption effect. One-sided shock absorber oil leakage will make the car body rise and fall, resulting in deviation.

In order to rapidly reduce the vibration of the frame and the car body and improve the smoothness and comfort of car driving, the car suspension system is generally equipped with shock absorbers. At present, two-way cylinder shock absorbers are widely used in cars.

Common damage performance of shock absorbers. If the shock absorber is broken, you can feel it when driving. If the stability of the vehicle is poor, the road surface will shake up and down if it is slightly uneven.When crossing an upside-down road, it would stop if you shake it up and down once or twice, but now it takes three or four times to stop, and the amplitude is getting bigger. This is a typical symptom of a broken shock absorber.

Car shock absorber fault check After determining that there is a problem or failure of the shock absorber, the first thing to check is whether the shock absorber has oil leakage or traces or phenomena of old oil leakage. The oil seal washer 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 invalid, and a new seal should be replaced.

After determining that there is a problem or malfunction of the shock absorber, you should first check whether the shock absorber has oil leakage or traces of old oil leakage. The oil seal gasket and sealing gasket are broken and damaged, and the nut of the oil storage cylinder head is loose. The oil seal and gasket may be damaged and invalid, and new seals should be replaced. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out.

Common faults of automobile shock absorbers. The vibration absorber is a wearable accessory in the process of automobile use. Whether the vibration absorber works well will directly affect the stability of the car and the life of other parts. Therefore, we should always keep the shock absorber in good working condition. The following methods can be used to check whether the vibration damper is working well.

What is the principle of the car shock absorber

1. Its working principle is that when there is a year-on-year movement between the frame (or body) and the axle, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly passes through different air holes. Enter the other cavity.

2. The working principle of the car shock absorber is that when there is a relative movement between the frame (or body) and the axle due to vibration, the vibration dampingThe piston in the device moves up and down, and the oil in the damper cavity repeatedly flows into another through different pores from one chamber.

3. Their working principle is that when the frame (or body) and the axle move relative to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another through different holes.

4. When compressing the stroke, it means that the wheels of the car move close to the body and the shock absorber is compressed. At this time, the piston in the shock absorber moves down. The volume of the lower chamber of the piston decreases, the oil pressure increases, and the oil flows through the circulation valve to the chamber (upper chamber) above the piston.

5. The automobile air shock absorber is called a buffer, which controls unwanted spring movement through a process called damping. The vibration absorber passesConvert the kinetic energy of the suspension movement into the heat energy that can be dissipated by hydraulic consumption to slow down and weaken the magnitude of the vibrational movement.

6. Description of the working principle of the two-way cylinder shock absorber: When compressing the stroke, the shock absorber is compressed, and the piston in the shock absorber moves down at this time. The volume of the lower chamber of the piston decreases, the oil pressure increases, and the oil flows through the circulation valve to the chamber above the piston.
