What are the shock absorbers for automobiles 5, what are the main shock absorbers for automobiles?

Automobile shock absorbers are:

1. Divided according to the angle of damping material.

1. Changgao hydraulic type:

Hydraulic shock absorbers are widely used in automotive suspension systems. The principle is that when the frame and the axle are reciprocating relative to each other, and the piston reciprocates in the cylinder barrel of the shock absorber, the oil in the shock absorber housing repeatedly flows from the inner cavity into the other inner cavity through some narrow pores. At this time, the friction between the liquid and the inner wall and the internal friction of the liquid edge ruler form a damping force on the vibration.

2. Pneumatic type:

The pneumatic shock absorber is a new type of shock absorber developed since the 60s. Its structure is characterized by a floating piston installed at the lower part of the cylinder barrel, and a closed air chamber formed by the floating piston and the cylinder barrel at one end is filled with high-pressure nitrogen. The floating piston is fitted with a large cross-section O-ring that completely separates the oil and gas.

The shock absorber of a car is made up of a spring and a shock absorber. The shock absorber is not used to support the weight of the body, but to suppress the energy of the spring shock absorption and absorb the impact of the road surface. The spring plays a role in softening the impact and reducing the impact of large energy multiple times.

If you've ever driven a car with a damper-damaged shock, you can feel the car's bouncing through every pothole, undulation, and aftermath that the shock absorber is designed to dampen that bounce. Without a shock absorber, it will not be possible to control the spring, and the car will have a serious jump when it encounters rough roads, and it will also cause the loss of tire grip and traction when cornering because of the spring up and down. It should be noted that the shock absorber of the car is not permanently used, so many people will ask, what is the detection method and replacement cycle of the car shock absorber?

Today we will talk to you about it.

The role of the shock absorberThe car shock absorber is a vehicle accessory used to suppress the spring shock absorption, which can be used to improve the comfort of vehicle driving. Uneven roads or poor driving conditions can cause the vehicle to wobble and jolt. In this case, the shock absorber can reduce the vibration, maintain the smoothness of the vehicle, and improve the comfort of the driver and passengers.

In other words, shock absorbers can reduce the feeling of bumps when driving. Quickly eliminate axle and wheel vibrations caused by bumpy road surfaces, ensure that the wheels grip the ground at any time, so as to ensure the steering and braking functions of the vehicle and improve the safety of vehicle driving. Damage to the shock absorber will directly affect the comfort, handling and smoothness of driving, and continued use will lead to damage to the chassis parts of the vehicle, and in serious cases, the braking effect will be affected.

Common types of shock absorbers are hydraulic shock absorbers, pneumatic shock absorbers, and resistance shock absorbers.

Abnormal situation of shock absorber 1, shock absorber oil leakage The cushioning effect is weakened, and the shock absorption and cushioning effect of the vehicle will be weakened. Oil leakage from the unilateral shock absorber will cause the body to be high on one side and low on the other, and the guide pants will cause the vehicle to deviate. If it is only a slight oil leakage, it will not affect the comfort of driving and riding, and it can be used in the short term; If the oil leakage is serious, it is recommended that you go directly to the 4S store for testing and replace it if necessary.

2. The rubber on the top of the shock absorber is aging and falling off, resulting in abnormal noise, when the vehicle shakes on the bumpy road, the top of the shock absorber will collide with other parts, if the rubber on the top of the shock absorber is aging and falling off, it will make an abnormal sound when it collides with other parts, and it is very likely to damage other parts 3. The fatigue of the shock absorber softens Causes damage to the shock absorber When the shock absorber spring fatigue is softened, the effect of shock absorption and cushioning of the vehicle will be significantly reduced. Since the shock absorber springs do not sufficiently dampen the vibrations of the body, the hydraulic pressure on the shock absorbers will increase and the burden will increase, resulting in a shortened service life. When it is found that the shock absorber has abnormal noise, too hard, soft and soft fingers, oil leakage, etc., it is necessary to consider replacing it.

In addition, if the vehicle brakes suddenly while driving slowly, and the vibration is very strong, it is possible that there is a problem with the shock absorber. Shock absorber is an important accessory related to driving comfort and safety, please go to the 4S shop in time to ask a professional maintenance technician to help detect.

It doesn't matter if you don't divide it, but I know less: there is nothing special to pay attention to in the car shock absorber, but there are some that need to be paid attention to:

1: The hardness of the shock absorber: the shock absorber is as the name of the hall orange is to give the car in the bumpy road section when driving can play a role in buffering, generally divided into: (1) hydraulic shock absorber, pneumatic shock absorber, resistance can.

2: The most noteworthy is Audi's quattro autonomous series, in which the Audi Q7 is kind.

Car shock absorber is also a car shock absorber, there is a good car shock absorber for car lovers who like off-road, sports models, the chain will not add points to the driving experience.

Automobile shock absorbers are composed of top pressure bearings, shock absorbers, dust jackets, buffer rubber piers, and coil spring shock absorbers.

Shock absorbers"The term is a common term within the automotive chassis industry, and an automotive shock absorber is actually a vibration damper. Shock absorbers are used not only in suspension but also in other locations in automobiles. For example, it is used in cabs, seats, steering wheels, etc., and can also be used as a buffer on vehicle bumpers.

In the suspension system, due to the vibration of the elastic element by the impact, in order to improve the smoothness of the car, the shock absorber is installed in parallel with the elastic element in the suspension, and the shock absorber is mostly a hydraulic shock absorber in the automobile suspension system, and its working principle is that when the frame (or body) and the axle are vibrated and there is a relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity flows into another cavity repeatedly from one cavity through different pores. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the automobile is converted into oil heat energy, and then absorbed and dissipated into the atmosphere by the shock absorber. When the cross-section of the oil channel and other factors remain unchanged, the damping spring force increases and decreases with the relative motion speed between the frame and the axle (or wheel), and is related to the oil viscosity.

Shock absorbers and elastic elements are responsible for the task of slowing impact and damping vibration, and excessive damping force will deteriorate the elasticity of the suspension and even damage the shock absorber connections. Due to the contradiction between the elastic element and the shock absorber, it is necessary to adjust the surface.

Detection method. 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 or 3 jumps, 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.Dismantle the shock absorber to stand upright, and clamp the lower end of the connecting ring on the vice, pull and press the damping rod several times, at this time there should be stable resistance, pull up (recovery) resistance 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.

Automobile shock absorber is an indispensable accessory in the driving of the car. If you want to describe what a shock absorber is, it can only be said that the shock absorber is a tube in the middle of the shock absorber of the car. It reduces unwanted vibrations by suppressing excess spring rebound from the spring.

In addition, the car shock absorber also has the ability to absorb part of the impact from the road surface, which can make the car more comfortable and stable.

Therefore, car shock absorbers are very important for cars. Once the levy reduction period and the damage fails, the car is prone to large bumps in the rough area, and sometimes it is even easy to cause rollover or loss of control of the vehicle. Moreover, in daily life, we often need to drive over speed bumps, and if our shock absorbers fail, then our car will become very unstable, so we need to check and replace the shock absorbers regularly.

Generally speaking, ordinary car shock absorbers need to be checked or replaced every 100,000 kilometers. When inspecting the shock absorber, we should pay attention to whether there are oil stains on the surface of the shock absorber, because generally speaking, the appearance of the shock absorber is dry and clean. If we find oil on the surface of the shock absorber, it means that the hydraulic oil inside it is overflowing, which means that our shock absorber needs to be replaced.

It should be noted that when replacing the shock absorber, we should try to replace the original shock absorber. After all, the original shock absorber is the one that best matches the vehicle. If we don't replace the original shock absorber, then it is still easy to have some accidents, such as in the process of driving, the vehicle deviates, or oil leakage and other problems.

In addition to seeing whether the shock absorber has oil stains, we can also judge whether the shock absorber is damaged by looking at whether the shock absorber has temperature, after all, the shock absorber will produce a certain degree of heat when working, and the shock absorber of the car that has just stopped generally has a temperature.

During the driving process, the vehicle does not deviate, maintains a normal speed, and does not cause engine failure, which can reduce vibration.

The shock absorber of the car is really very important for the car, because this shock absorber will reduce some fluctuations of our car, will make the car longer in life, and then it will also make the car have a certain stability.

It will also keep the car from jolting during driving.

It will reduce the feeling of bumps, will make the car more stable, make the car safer, can reduce unnecessary vibrations, can relieve the impact force, and can improve the comfort of the driver.

The role of automobile shock absorber: mainly in order to make the vibration of the frame and the body quickly attenuated, improve the smoothness and comfort of the car, the automobile suspension system is generally equipped with a shock absorber, and the two-way action cylinder shock absorber is widely used in the car. The shock absorbing spring is mainly used to absorb the bumps and vibrations caused by the uneven road surface during the driving process, but the spring as an elastic element, while absorbing and filtering the bumpy vibration of the road surface, it will also produce reciprocating bounce motion, and the main function of the shock absorber is to inhibit the attenuation of the natural vibration of the repeated bounce acceleration spring after absorbing the various impacts brought by the road surface, so as to provide better driving comfort for the vehicle.

The most important role is to cushion the vibration, it can make the car more stable driving, give passengers comfort, will not easily feel bumpy, when the car encounters speed bumps, etc., the role of shock absorbers is more obvious.
