Springs can be divided into the following six categories:
1, torsion springs, is subjected to torsional deformation of the spring, its working part is also dense winding into a spiral. Torsion spring end structure is processed into various shapes of torsion arms, rather than hook and loop. Torsion springs utilize the principle of leverage, by twisting or rotating the elastic material of soft and tough material, so that it has great mechanical energy.
2, extension springs are coil springs subjected to axial tension. When not subjected to load, extension springs are generally tightened between the coil and coil without clearance.
3, compression spring is subjected to axial pressure of the coil spring, it is used in the cross-section of the material for the round, but also rectangular and multi-stranded steel haunted coil system, the spring is generally equal pitch, the shape of the compression spring: cylindrical, conical, convex and concave and a small number of non-circular, etc., the compression spring will have a certain gap between the spring circle and the circle, when subjected to an external load spring contraction and deformation, and storage of deformation energy. The spring contracts and deforms when subjected to an external load, storing the deformation energy.
4, progressive springs, this spring adopts a thick and thin, sparse and dense design, the advantage is that the pressure is not big when the coefficient of elasticity of the lower part of the road can be absorbed through the undulation, to ensure ride comfort, when the pressure increases to a certain extent after the thicker part of the spring to play a role in supporting the body, but the disadvantage of this kind of spring is that the handling feeling is not direct, accuracy is poor.
5, linear springs, linear springs from top to bottom of the thickness, sparseness, elasticity coefficient is a fixed value. This design of the spring can make the vehicle to get more stable and linear dynamic response, is conducive to the driver better control of the vehicle, mostly used in performance-oriented tuned cars and competitive vehicles, the downside is, of course, the comfort is affected.
6, short spring short spring compared to the original spring to be shorter, and more robust.
