How to judge whether the shock absorber of the car is damaged?

Press the bumper hard and then release it. If the car jumps 2 to 3 times, it means that the shock absorber is working well. When the car drives slowly and brakes urgently, if the car vibrates violently, it means that there is something wrong with the shock absorber.

Usually, the shock absorber housing is hot. If the shock absorber shell is cold, it means that the damper is damaged; when the car stops, when you press and release the corner of the car body, the body will rebound under the action of spring force.

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.

The performance of a broken car shock absorber is as follows: when driving through a large pothole or raised road, the vehicle will have the sound of metal collision and more than one vibration will occur. The grip of the rear wheel slides, and it is easy to swing the tail or insufficient steering. When the shock absorber is abnormal, the car body will shake abnormally.

Observe whether there is oil leakage. After the failure of the car shock absorber, we should first observe whether there is oil leakage. If there is oil leakageMoreover, we should tighten the cylinder head nut. If it is still a nut after tightening, it means that the oil seal or sealing gasket is damaged. At this time, a new seal needs to be replaced.

Daily repair and maintenance of car comfort shock absorber

1. If the resistance is unstable or there is no resistance, it may be a lack of oil inside the shock absorber or damage to the valve parts, which should be repaired or replaced. After determining that there is a problem or malfunction of the shock absorber, you should first check whether the shock absorber has traces of oil leakage or 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.

2. If it is unstable or has no resistance, it may be that the shock absorber lacks oil or parts are damaged, and new parts should be repaired or replaced.

3. If there is no oil leakage in the shock absorber, you should check whether the shock absorber connection pin, connecting rod, connection hole, rubber, bushing, etc. are damaged, desolded, cracked or fallen off.

4. The main function of the shock absorber is to ensure the smoothness and comfort of the moving car, so its overhaul and maintenance cannot be ignored. The editor here introduces some tips for the majority of car owners and netizens to quickly check the work and maintenance of shock absorbers.

5. The maintenance of the shock absorber is very important. The car shock absorber is a fixed part of the car chassis. In order for the car to feel like they want to be on the flat ground in the car, the better the better the car shock absorber. That is to say, if the shock absorber of your car can work properly, your sense of bump will be relatively reduced when the car passes through the uneven road surface.

6. Our daily driving style is very important. First of all, we should park the car in a flat position, then drive slowly when crossing the speed bump. Don't pull heavy objects for a long time, and finally bypass the manhole covers and big pits on the road. Why should the car shock absorber be maintained? Whether the shock absorber is a wearable part depends on the usual road conditions.

Common faults of automobile shock absorbers

The abnormal sound of shock absorbers may have the following reasons: 1. The shock absorber is leaking oil. Shock absorber bending, etc. Abnormal noise caused by aging or abnormal wear of damping pressure bearings. The deformation of the damping spring causes damage to the rubber sleeve of the abnormal sound balance rod, or there is a gap between the connecting ball heads.

The rubber parts of the shock absorber top glue, arm rubber sleeve, and balance rod ear are aging and hard, and the rubber parts are hardened and squeezed, which will make a squeak.The damper failed, causing the shock absorber to make a strange sound.

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.

The performance of car shock absorber failure is as follows: oil leakage. Check the shock absorber through the wheel arch through the flashlight. When oil leakage is found outside the shock absorber, it indicates that the shock absorber has been damaged. The chassis is loose.

Common faults cause the car to stop after driving 10km on the road with poor road conditions, and touch the damper shell with your hand. If it is not hot enough, it means that there is no resistance inside the damper and the damper does not work.

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.

What is the principle of car shock absorption?

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 damper moves up and down, and the oil in the damper cavity repeatedly enters another cavity through different pores.

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

When compressing the stroke, it means that the wheels of the car move closer 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.

The working principle of automobile shock absorbers is actually to assume the task and role of shock absorption through a connection between shock absorbers and bouncing parts.

Their working principle is that when the frame (or body) and the axle move relative to the 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.

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

common faults and overhaul of car shock absorbers

Common damage to hydraulic shock absorbers includes shock absorber oil leakage, rubber aging and shedding on the top of the shock absorber, shock absorber spring fatigue softening, 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 the upside down, it would have been shaken up and down once or twice.It will stop. Now it takes three or four times to stop, and the amplitude is getting bigger, which is a typical symptom of a broken shock absorber.

What is the function of car shock absorbers?

1. The function of car shock absorbers. Roads with uneven roads or poor driving conditions will cause vehicles to shake and bump. At this time, the function of the shock absorption device is reflected, which can reduce vibration, maintain the ride comfort of the vehicle, and improve the comfort performance of drivers and passengers. In other words, it is to reduce the bumpy feeling when the vehicle is driving.

2. The function of the shock absorber is to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface to improve the smoothness of the car. There are three types of shock absorbers used in cars: two-way cylinder shock absorbers, inflatable shock absorbers and damping adjustable shock absorbers.

3. [Pacific Automobile Network] The function of automobile shock absorbers is to slow down the expansion and compression speed of the spring, while absorbing the vibration caused by it. When the spring is deformed, it can be quickly stabilized, thus improving the ride comfort of drivers and passengers.

4. The word shock absorber 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.

5. The function of shock absorber: support the car body. Transmit all kinds of reaction forces facing the car body. Ease the body impact and reduce the body vibration. Suppress the beating of the vehicle, improve the grounding of the tires to the ground, and ensure the safety of the vehicle.
