The spring is a mechanical part with elasticity.It is indispensable to the almost all machines.The type of springs are complex and diverse.
The springs can be divided into the following six categories:
1.Torsion spring: stand the deformation of the spring,its working part is also wound tightly into a spiral. Torsion spring end structure is processed into various shapes of the torsion arm,not the hook ring.Torsion spring adopt the principle of leverage,make it has great mechanical energy.
2.Tension spring: stand the axial tension of the coil spring. In the absence of load, the tension spring are generally tight and no gap.
3.Compression spring: bear the axial pressure of the coil spring,the material cross section mostly is circular,compression spring have a certain gap,when the external load make spring shrinkage deformation,it storages deformation energy.
4.Progressive spring: a thick, dense inconsistent design,the advantage:when the pressure is not large,it can ensure ride comfort;when the pressure increased to a certain degree,the thicker part of the spring will support the body.But the shortcomings is not easy to control,the accuracy is poor.
5.Linear spring: density is unchanged,so the elasticity is a fixed value.This design can make the vehicle obtain a more stable and linear dynamic response,control the vehicle better by driver,of course, the comfort is affected.
6.Short spring: be shorter,and more sturdy,can reduce effectively the body center of gravity,more stable,smooth.
