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

An importer asked me what he should do when Chinese factories ask for his “price targets”. I think it is a legitimate question from factories Here is the sequence I advise importers to follow, when they source new suppliers: If this is not easy, continue discussing via email and phone, and pay for factroy audits once have narrowed your search down to 1 or 2 candiates. Don’t hesitate to give them your target price if it is very different from what they offer you. Ask them to justify their price level precisely. Don’t forget, in China price is very closely tied to quality.  If you negotiate a very low price, most suppliers will end up saying yes. Then they will wonder how to make your products. They will probably use the very cheapest materials and subcontract production in a small workshop. You will get what you pay for. One last piece of advice: if you pay 20% above market price, all you risk is wasting 20% of the money you disbursed for your project (and actually it is closer to 10-15% because the FOB price is only a portion of your total landed cost). If you pay 20% below market price, you risk getting something that can’t be sold at all (which means you risk losing all your investment). Do you agree?  I am cathy from Max Auto Ltd ,if you have any inquiry to China , we can help you source any parts from China . We specialize in manufacture and export all the components for shock absorber , for example piston rod , sintered part , shims , oil seal , stamping part and coilover .

Mcphersonindependent suspension is an important part of the safety structure of the car. For a long time, the driving control and comfort of the car are closely related to the suspension system in the chassis structure, and the simplicity and complexity of the suspension structure also directly determines the cost of automobile manufacturing. the level of. Mcphersonindependent suspension is one of many suspension systems, which has won a wide range of market applications due to its simple structure, low cost and acceptable comfort. Development history:In the human body, bones are often connected by soft tissue, which acts as a buffer to protect the bones and insulates excess vibration from traveling to the brain and damaging brain cells. In the composition structure of the car, the role of the suspension system is just the same as the soft tissue in the human body structure. The suspension system is the whole support system composed of the elastic components, shock absorber and force transmission devices between the body and the tire. These three components are responsible for buffering, damping and force transmission respectively. The specific responsibility of the suspension system is to support the car body, filter out the unnecessary shaking of the road, and provide a smooth and comfortable riding environment for drivers and passengers. So far, the suspension system has formed independent, semi-independent and non-independent three types. In modern cars, most use independent suspension, according to different structural forms, independent suspension can be divided into transverse arm type, longitudinal arm type, multi-link type, candle type and McPherson type. And in many kinds of independent suspension, McPherson type and simple structure, low cost, comfort is the most widely used. The McPherson independent suspension has been in use since its invention, but its structure has evolved into a complex system that now includes
