According to the nature of the force, the spring can be divided into tensile spring, compression spring, torsion spring and bending spring, according to the shape can be divided into disc spring, annular spring, plate spring, spiral spring, cut cone coil spring and torsion bar spring, according to the production process can be divided into cold coil spring and hot coil spring.Because of the simple manufacture of ordinary cylindrical spring, and can be made into various types according to the loading situation, the structure is simple, so the most widely used.Spring manufacturing materials should generally have high elastic limit, fatigue limit, impact toughness and good heat treatment performance, commonly used carbon spring steel, alloy spring steel, stainless spring steel and copper alloy, nickel alloy and rubber, etc.Springs are made by cold winding and hot winding.Spring wire diameter is less than 8 mm with cold rolling method, more than 8 mm with hot rolling method.Some springs are made after strong pressure or shot peening processing, can improve the bearing capacity of the spring.

Springs can be divided into the following 6 categories:
1. Torsional spring is a spring that bears torsional deformation, and its working part is also tightly wound into a spiral.The torsion spring end structure is machined into various shapes of torsion arms, rather than hook rings.The torsion spring uses the lever principle to twist or rotate the elastic material with soft and large toughness, so that it has great mechanical energy.
2. The tension spring is a spiral spring that bears the axial tension.When not bearing the load, the stretch spring between the ring and the ring is generally tight and no gap.
3, compression spring is under axial pressure of the spiral spring, it is used in the data section for more rounded, useful also rectangle and multi-strand steel rolled a travelling, spring is usually pitch, such as the shape of the compression spring are: cylindrical, conical, convex and concave and a small amount of noncircular, compression spring circle and circle will have a certain gap between, when under external load spring contraction deformation, deformation energy storage.
4, gradual type spring, the spring is not consistent design adopted the thickness, density, benefit is in compression is not able to absorb the road through the lower part of the elastic coefficient of the ups and downs, guarantee the ride comfort, when the pressure increases to a certain degree of thicker part of the spring have the effect of support body, and this spring disadvantage is that the manipulation of the feelings are not directly, poor accuracy.
5, linear spring, linear spring from top to bottom of the thickness, density unchanged, elastic coefficient is a fixed value.This kind of spring design can make the vehicle obtain more stable and linear dynamic response, which is conducive to the driver to better control the vehicle. It is mostly used in performance oriented modified vehicles and competitive vehicles, but the disadvantage of course is that comfort will be affected.
6, short spring short spring is shorter than the original spring, and more robust, installation of short spring, can effectively reduce the body center of gravity, reduce the roll of the bend, make the bend more stable, smooth, improve the vehicle curve control.The original shock absorber damping Settings to comfort, so a short spring and original shock absorber on the match is not very stable, it will not be able to effectively inhibit short rebound and compression spring, driving on the bumpy road, there will be a feeling of discomfort jumps, in the long term, shock absorber can greatly shorten the life of a, and there are oil leakage may occur.Of course, the above conditions are relatively speaking. If you drive daily, there will be no such serious damage, and try not to drive intensely. After all, the original shock absorber cannot withstand the pressure of high load. 

Torsion spring
Torsion spring (torsion spring) using the principle of lever, through the material of soft torsion spring torsion spring soft, large toughness of the elastic material distortion or rotation, so that it has great mechanical energy.Is the spring that bears torsion deformation, its working part also is each circle or close around or separate around.The end structure of the torsion spring is processed into various shapes of torsion arms, from single torsion to double torsion, and even the deformation of various torsion bars can be shaped according to the design.Torsional spring is often used in machinery balance mechanism, in the automobile, machine tools, electrical appliances and other industrial production is widely used.

Compression spring
Compression spring (compression spring) is under axial pressure of the spiral spring, a spring compression spring compression spring divided into pitch spring and defection is apart from the spring, such as the shape of the compression spring: in cylindrical, conical, convex and concave and a small amount of noncircular compression spring there is a certain gap between circle and circle, when under external load spring contraction deformation, deformation energy storage.The variable pitch spring is more and more common, not just equal pitch spring, variable pitch spring can play a different role in different environments. 

Carbon nanospring
Carbon nanotube springs can be up to hundreds of microns in diameter, and length can be up to a few centimeters, its spinning structure has a broad application prospect, is expected to be applied in a scalable and flexible conductor electrode, micro strain sensor, super capacitor, integrated circuit, solar cell, field emission source, energy dissipation, fiber, and other fields, for the preparation of the visible carbon nanotube electronics provides a possible, also is expected to be applied to medical apparatus and instruments, such as tensile sensing bandages, etc.The new structure can also be developed into multi-functional carbon nanotube fiber composites for utilization. 

Stretching the spring
Tensile springs (tension springs) are spiral springs that bear axial tension. Tensile springs are generally made of circular cross section materials.When not bearing the load, the stretch spring between the ring and the ring is generally tight and no gap.It is used to control the movement of the machine parts, store energy, measure the size of the force, etc. It is widely used in machines and instruments.The form of the hook has side hook spring, long hook spring, English hook spring, German hook spring, semicircle hook spring, duck mouth hook spring and so on, its material has stainless steel, qin steel, high carbon steel, phosphorous copper, beryllium copper, oil tempered alloy spring steel. 

Air spring
Air spring is in the flexible airtight container, adding pressure air using the compressibility of air spring spring is a non-metallic elastic effect, can be roughly divided into capsule type and membrane type two kinds, air spring has good elastic properties, in the high-end vehicle suspension device can greatly improve the vehicle ride comfort, thus greatly improve the comfort of the vehicle operation, so the air spring in automobile, railway locomotive has been widely used.In addition, because the air spring and ordinary steel spring have many advantages, so it is also used in some mechanical equipment, precision instruments.
