Automobile suspension is an elastic device connecting frame and axle in automobile. It is generally composed of elastic components, guide mechanism, shock absorber and other components, the main task is to ease the impact from uneven road to the frame, in order to improve the comfort of the ride: 1.the car suspension including elastic components, shock absorber and force transmission device and other three parts, these three parts respectively play a buffer, vibration reduction and force transmission. 2. coil spring: is the most used spring in modern cars. It has strong impact absorption ability and good ride comfort; The disadvantage is that the length is large, occupy more space, the contact surface of the installation position is also large, so that the layout of the suspension system is difficult to be very compact. Because the coil spring itself can not bear the transverse force, so in the independent suspension has to use four link coil spring and other complex combination mechanism. 3. leaf spring: mostly used in vans and trucks, by a number of different lengths of slender spring pieces combined. It is simpler than coil spring structure, low cost, compact assembly at the bottom of the body, the work of each piece friction, so it has its own attenuation effect. But if there is significant dry friction, it will affect the ability to absorb the impact. Modern cars, which value comfort, are rarely used. 4. Torsion bar spring: it is a long rod made of twisted and rigid spring steel. One end is fixed on the body, and one end is connected with the upper arm of the suspension. When the wheel moves up and down, the torsion bar has torsional deformation and plays the role of spring.

Complete Shock Strut is composed of shock absorber, lower spring pad, dust jacket, spring, shock absorber pad, upper spring pad, spring seat, bearing, top glue and nut. Complete Shock Strut uses fluid to convert the elastic energy of the spring into heat energy to make the vehicle movement convergence the most reasonable, so as to eliminate the vibration of the road surface to improve the driving stability, and give the driver comfort and stability. 1.Composition and structure: The Complete Shock Strut is composed of shock absorber, lower spring pad, dust jacket, spring, shock absorber pad, upper spring pad, spring seat, bearing, top glue and nut. Complete Shock Strut is divided into front left, front right, left, right four parts, each part of the shock absorber at the bottom of the ear (horn connected to the brake disc) position is different, so in the selection of Complete Shock Strut must be aware of which part of the Complete Shock Strut.  Most of the front damper on the market is the Complete Shock Strut, after the shock absorber is still ordinary 2.Difference with shock absorber: Difference with shock absorber composition structure. Complete Shock Strut is distinguished from shock absorber. Complete Shock Strut is distinguished from shock absorber. 1.The shock absorber is only part of Complete Shock Strut;  Complete Shock Strut is composed of shock absorber, lower spring pad, dust jacket, spring, shock absorber pad, upper spring pad, spring seat, bearing, top glue and nut. 2. Different difficulty of replacement The replacement of independent shock absorbers is difficult to operate, requiring professional equipment and technicians, and the risk factor is large;  Replacing Complete Shock Strut is a simple matter of turning a few screws. 3. Price difference It is expensive to replace each part of shock absorber set separately.  Complete Shock Strut, which

Automobile shock absorber damage, the most obvious phenomenon is the car in the process of running jump, brake will appear abnormal sound. Auto shock absorber is in order to protect the body and frame, the car driving process, reduce the vibration of the body and frame to produce, so as to improve the ride comfort and comfort of vehicle driving, the car suspension system is composed of a spring and damper cylinder, belongs to a kind of consumables, use for a long time can lead to shock absorber. If the car shock absorber is broken, the car produced by shaking the better in the rugged road, tires can lose grip, the rear wheels lose grip will make the car produces a spin phenomenon, because of the shock absorber failure, the safety factor of the car will be reduced, the car brakes or likely to occur during a lane change, also can reduce auto control and control performance is poor, Prone to danger. The quality of the shock absorption system directly affects the comfort of the car, so the car in the process of driving do not fierce, must slow down when the speed bump, should make the shock absorber often just in a good working state, if there is a problem must be repaired in time. Shock absorber is broken what symptom can you have A broken shock absorber will appear the following symptoms: 1, the car over a bumpy road or speed bump, a wheel issued a “MAO” sound. 2. The car in bad road conditions for a distance, and then touch the shell of each shock absorber.  Under normal circumstances, the shell of the shock absorber should have a temperature, and the temperature indicates that the shock absorber is working.  If the shock absorber shell is cold, there

Historical origin “Dragon Boat Festival” “end” the original meaning of the word “is”, “noon” for “.  “Dragon Boat Festival” (Dragon Boat Five), “zhongzheng” also, the noon is in the middle of the.  The ancient people took the heavenly stem and earth branch as the carrier, the heavenly stem carried the way of heaven, and the earth branch carried the way of earth. They set the heavenly stem and Earth branch as the transport of heaven and earth personnel, and the heavenly stem and Earth branch was common in the era. Traditional custom The Dragon Boat Festival is a very popular Chinese folk festival, the Dragon Boat Festival, is the Traditional habit of the Chinese nation since ancient times, because of the vast area, plus many stories and legends, so not only produced a number of different festival name, but also around the country has not the same customs. Midsummer Dragon Boat Festival is an auspicious day for the flying dragon in the sky. The Dragon Boat Festival is an important theme of etiquette and customs in the form of Dragon Boat Festival. This custom is still prevalent in the southern coastal areas of China. Dietary habit Commonly known as zongzi, is made of glutinous rice and stuffing. It is wrapped by reed leaves (or leaves) and has various shapes such as sharp corners and quadrangles. Zongzi has a long history and was originally used as a sacrifice to the ancestors. Into the north, with millet (northern millet) to make zongzi, said “jiao Shu”. Due to the different dietary habits around the formation of the north and south flavor reed;  In terms of taste, zongzi are divided into two categories: salty and sweet.

How does shock absorber / shock struts Guarantee the stability of your car Concept： The shock absorber is used to suppress the shock and the impact from the road surface when the spring rebounds after shock absorption. Widely used in automobiles, in order to accelerate the attenuation of the vibration of the frame and the body to improve the driving stability of the car. working principle In the suspension system, the elastic element vibrates due to the impact. In order to improve the ride comfort of the car, a shock absorber is installed in parallel with the elastic element in the suspension to dampen the vibration. The working principle is that when the frame (or body) and the axle vibrate and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly passes through a different cavity. The pores flow into another cavity. 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 car is converted into the heat energy of the oil, which is then absorbed by the shock absorber and released into the atmosphere. When the oil channel section and other factors remain unchanged, the damping force increases or decreases with the relative movement speed between the frame and the axle (or wheel), and is related to the oil viscosity. (1) During the compression stroke (the axle and the frame are close to each other), the damping force of the shock absorber is small, so that the elastic effect of the elastic element can be fully exerted to ease the impact. At this time, the elastic element plays a major role. (2)

piston composition：Piston components include: pistons, piston rings, support rings, piston rods, etc. According to different structural forms, pistons can be divided into cylindrical pistons (the length is larger than the diameter), disc pistons (the length is smaller than the diameter), differential pistons, combined pistons and plunger pistons. After rolling, the reduction of surface roughness value can improve the fit properties. At the same time, the friction damage to the seal ring or the seal when the cylinder rod and piston moves is reduced, and the overall service life of the oil cylinder is improved. The rolling process is an efficient and high-quality process measure.Material characteristics：Material:C35,C45,40Cr；Surface treatment:Chrome plating ,Nickel-Chrome plating；Size:Customized or current modelsThe role of the piston rod：The function of the piston rod is to connect the piston and the crosshead, transmit the force acting on the piston and drive the piston to move.Basic requirements for the piston rod:(1) There must be sufficient strength, stiffness and stability;(2) Good wear resistance and high machining accuracy and surface roughness requirements;(3) Minimize the influence of stress concentration on the structure;(4) Ensure reliable connection and prevent loosening;(5) The design of the piston rod structure should facilitate the disassembly and assembly of the piston.Piston rod overheating(1) When the piston rod and the stuffing box are assembled, there is a deflection, which causes local mutual friction, and should be adjusted in time;(2) The holding spring of the sealing ring is too tight and the friction force is large, so it should be adjusted appropriately;(3) The axial clearance of the sealing ring is too small, and the axial clearance should be adjusted according to the specified requirements;(4) The amount of oil supplied is insufficient, and the amount of oil should be appropriately increased;(5) The running-in of the piston rod and the sealing ring is poor, and the running-in

Knowledge of shock absorber daily maintenance In order to make the vibration of the frame and body decay quickly, improve the ride comfort and comfort of the car, the automobile suspension system is generally equipped with shock absorbers.Shock absorbers are vulnerable parts in the process of automobile use. The working quality of shock absorbers will directly affect the stability of automobile driving and the life of other parts. Therefore, we should make the shock absorbers often 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 10km on the road with poor road conditions, touch the shell of the shock absorber by hand. If it is not hot enough, there is no resistance inside the shock absorber and the shock absorber does not work. At this time, the appropriate lubricating oil can be added, and then the test, if the shell heat, for the shock absorber internal lack of oil, should add enough oil; Otherwise, the shock absorber fails. 2. Press the bumper firmly and then release it. If the car has 2~3 jumps, the shock absorber works well. 3.When the car is moving slowly and braking in an emergency, if the car vibrates violently, there is a problem with the shock absorber. 4.Remove the shock absorber to the upright, and connect the bottom ring clamp on the vise, pull reduce vibration lever several times, this time should be stable resistance, pull up resistance should be greater than the resistance when pressing down on them, such as unstable resistance or without resistance, may be internal lack of oil damper or valve parts damaged, should be repaired or replacement parts.After determining the shock absorber has a problem or failure, we should first check whether the shock absorber has oil leakage or traces

Multi-link independent suspension is composed of connecting rod, shock absorber and shock absorber spring.  It has more links than the general suspension, according to the convention, generally put 4 links or more links structure of the suspension, known as the multi-link. Functional characteristics： Multi-link suspension can not only ensure a certain comfort, but also because there are more links, the wheels and the ground can be as vertical as possible, as far as possible to reduce the body tilt. Maximum possible maintenance of tyre adhesion. Its control performance and double fork arm suspension are hard to distinguish, high-grade cars due to ample space, and pay attention to comfort performance and control stability, so most of the use of multi-link suspension, it can be said that multi-link suspension is the best partner of high-grade cars.  Material characteristics： Multi-link suspension structure is relatively complex, material cost, research and development experiment cost and manufacturing cost are much higher than other types of suspension, and its space occupation is large, medium and small cars for cost and space consideration rarely use this kind of suspension. Function： As the name implies, the multi-link suspension is composed of three or more connecting rods, and can provide multiple direction control force, so that the tire has a more reliable driving track suspension structure.  However nowadays, because 3 connecting rod structure already cannot satisfy people to chassis control the higher pursuit of performance, only the structure is more accurate, more accurate positioning 4 connecting rod type and 5 connecting rod type suspension can be said to be true multi connecting rod type, these two kinds of suspension structure are usually applied to the front wheel and rear wheel respectively.  Take the five-link suspension which is often used in the rear wheels as an example. The five links respectively refer to
