According to the nature of the force, the spring can be divided into a tension spring, a compression spring, a torsion spring and a bending spring. According to the shape, it can be divided into a disc spring, a ring spring, a leaf spring, a coil spring, a truncated cone scroll spring and a torsion bar spring. According to the production process, it can be divided into a cold coil spring and a hot coil spring. Ordinary cylindrical springs are widely used because they are simple to manufacture and can be made into various types according to the load conditions. Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment properties. Commonly used are carbon spring steel, alloy spring steel, stainless spring steel, and copper alloy, nickel alloy and rubber. Wait. Springs are manufactured by a cold roll method and a hot roll method. The general-purpose cold-roll method in which the spring wire diameter is less than 8 mm and the hot-roll method in which the spring wire diameter is larger than 8 mm. Some springs are subjected to strong pressure or shot peening after being made to improve the load carrying capacity of the spring.
According to the "China Spring Manufacturing Industry Production and Sales Demand and Investment Forecast Analysis Report" [2] statistics, springs can be divided into the following seven categories:
1. A coil spring is a torsion spring, which is a spring that undergoes torsional deformation, and its working part is also tightly wound into a spiral shape. The torsion spring end structure is a twisted arm that is machined into various shapes, rather than a hook and loop.
2. The tension spring is a coil spring that receives axial tension. When the load is not subjected to load, the ring of the tension spring is generally tight and has no gap between them.
3. The compression spring is a coil spring that bears the pressure. The material used is mostly circular in shape. It is also rolled with rectangular and multi-strand steel. The spring is generally of equal pitch. The shape of the compression spring is: cylindrical. , conical, convex and concave, and a small number of non-circular, etc., there will be a certain gap between the ring and the ring of the compression spring. When subjected to external load, the spring shrinks and deforms, and the deformation energy can be stored.
4. The torsion spring uses the principle of leverage to make it have great mechanical energy by twisting or rotating the elastic material with soft material and high toughness.
5. Progressive spring, this kind of spring adopts the design of inconsistent thickness and density. The advantage is that when the pressure is not large, the undulation of the road surface can be absorbed by the part with lower elastic coefficient to ensure the comfort of riding, when the pressure increases. After a certain degree, the thicker part of the spring acts to support the body, and the disadvantage of this type of spring is that the handling feel is not direct and the accuracy is poor.
6, linear spring, linear spring from top to bottom thickness, density and constant, the elastic coefficient is a fixed value. This design of the spring can make the vehicle obtain a more stable and linear dynamic response, which is beneficial for the driver to better control the vehicle, and is often used for performance-oriented modified cars and competitive vehicles. Of course, the comfort is affected.
7. Short spring short spring is shorter than original spring, and it is more sturdy. Short spring is installed, which can effectively reduce the center of gravity of the vehicle body, reduce the roll generated during cornering, make the cornering more stable and smooth, and improve the vehicle bending. Road handling. The damping setting of the original shock absorber is biased, so the short spring and the original shock absorber are not very stable in cooperation. It can not effectively suppress the rebound and compression of the short spring. When driving on bumpy roads, it will There is an uncomfortable jump feeling. In the long run, the life of the shock absorber will be greatly shortened, and there may be oil leakage. Of course, these conditions are relatively speaking, there will be no such serious damage when driving daily, and try not to drive drastically. After all, the original shock absorber can not withstand the pressure of high load.
Air spring
Torsion spring
The torsion spring (torsion spring) uses the principle of the lever to make it extremely powerful by twisting or rotating the elastic material with soft material and high toughness.
Torsion spring
Mechanical energy. It is a spring that is subjected to torsional deformation, and its working part is also surrounded by circles or surrounded or separated. The end structure of the torsion spring is a torsion arm machined into various shapes, from single twist to double twist, or even deformation of various torsion bars, and is designed according to the design. Torsion springs are commonly used in mechanical balancing mechanisms and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.
compressed spring
The compression spring (pressure spring) is a coil spring that receives axial pressure. The spring is generally of equal pitch. The shape of the compression spring is: cylindrical, conical, convex and concave, and a small amount of non-circular shape. There is a certain gap between the ring of the compression spring and the ring. When subjected to an external load, the spring shrinks and deforms, and the deformation energy can be stored.
compressed spring
Carbon nanospring
Carbon nanotube springs can reach hundreds of micrometers in diameter and can reach several centimeters in length. The spinning structure has broad application prospects and is expected to be applied to retractable conductors, flexible electrodes, micro strain sensors, supercapacitors, integrated circuits, solar cells. Fields, field emission sources, energy dissipative fibers, etc., provide the possibility to produce macroscopic carbon nanotube electronic devices, and are also expected to be applied to medical devices, such as tensile force bandages. This new structure can also be developed into a multi-functional carbon nanotube fiber composite material for use.
Extension spring
The tension spring (tension spring) is a coil spring that receives axial tension, and the tension spring is generally made of a circular cross-section material. Stretching when not under load
Spring
The ring and the ring of the spring are generally tight and have no gap. It uses the resilience (tension) after stretching to control the movement of the machine, the energy stored, and the measurement force. It is widely used in machines and meters. The hooks are in the form of side hook tension springs, long hook tension springs, English hook tension springs, German hook tension springs, semicircular hook tension springs, duckbill hook tension springs, etc. The material is stainless steel "target=_blank> stainless steel , Qin steel, high carbon steel, phosphor bronze, oil tempered alloy spring steel.
