Spring can be divided into the following 6 categories:
　　1, reverse the spring, is to withstand the torsion deformation of the spring, its working part is also densely wound into a spiral. Torsion spring end structure is processed into various shapes of the torsion arm, instead of hook ring. Torsion springs use the principle of leverage, through the soft material, toughness of the larger elastic material distortion or rotation, so that it has great mechanical energy.
　　2, stretch spring is to withstand the axial tension of the coil spring. When not under load, the tension spring is generally tight and there is no gap between the rings.
　　3, the compression spring is to withstand the axial pressure of the coil spring, which is used in the cross-section of the material is mostly circular, but also useful for rectangular and multi-strand steel hanging roll, the spring is generally equal pitch, the shape of the compression spring cylindrical Shaped, conical, convex and concave and a small number of non-circular, etc., there will be a certain gap between the compression spring ring and the ring, when subjected to external load when the spring shrinkage deformation, storage deformation energy.
　　4, progressive spring, the spring thickness, density inconsistent design, the advantage is less pressure can absorb the road through the lower part of the coefficient of fluctuation, to ensure ride comfort, when the pressure increases to After a certain degree of coarser part of the spring to play the role of supporting the body, and the disadvantage of this spring is not directly manipulated feelings, the accuracy is poor.
　　5, linear spring, linear spring thickness from top to bottom, density unchanged, the elastic coefficient is a fixed value. This design of the spring allows the vehicle to obtain a more stable and linear dynamic response, helps the driver to better control the vehicle, and more for the performance-oriented modified cars and competitive vehicles, of course, the comfort of the affected comfort.
　　6, short spring short spring compared to the original spring to be shorter, and more sturdy, the installation of short springs, can effectively reduce the body center of gravity, reducing the cornering generated when the roll, the cornering more stable and smooth, enhance the vehicle bend Road control. The damping of the original shock absorber set bias comfortable, so the short spring and the original shock absorber with the cooperation is not very stable, it can not effectively inhibit the short spring rebound and compression, driving in the bumpy road, will be There is a sense of discomfort jumping, the long run, shock absorber life will be greatly reduced, but there may be oil spills. Of course, these conditions are relatively speaking, the daily driving, then there will be no such serious damage, but try not to drive intense, after all, the original shock absorbers can not withstand the heavy load of sturdy, the installation of short springs, can effectively reduce the body center of gravity , To reduce the cornering generated when cornering, cornering more stable, smooth, improve vehicle cornering control. The damping of the original shock absorber set bias comfortable, so the short spring and the original shock absorber with the cooperation is not very stable, it can not effectively inhibit the short spring rebound and compression, driving in the bumpy road, will be There is a sense of discomfort jumping, the long run, shock absorber life will be greatly reduced, but there may be oil spills. Of course, these conditions are relatively speaking, the daily driving then there will not be such a serious damage, but try not to drive intense, after all, the original shock absorber can not withstand the pressure of high load.
