Pinggood springs can be divided into the following five categories:
1, pinggood spring torsion spring, is to withstand the torsional deformation of the spring, and its working part is also a tight spiral into a spiral. The torsion spring end structure is a torsion arm that is machined into various shapes rather than a hook. The torsion spring utilizes the principle of leverage to twist or rotate a flexible, tough material with a large amount of mechanical energy.
2. The pinggood spring tension spring is a coil spring that bears axial tension. When not under load, the tension spring is normally tight and tight without any gap between the ring.
3, pinggood spring compression spring is to withstand the axial pressure of the coil spring, it uses a material section is mostly round, but also useful rectangular and multi-strand steel roll, the spring is generally equal pitch, the shape of the compression spring There are: cylindrical, conical, convex and concave shapes and a small amount of non-circular, etc., there will be a certain gap between the coil and the coil of the compression spring, when the external load is received, the spring will shrink and deform, and the deformation energy will be stored. .
4, progressive spring, this spring adopts the design of thickness, density and inconsistency, the advantage is that when the pressure is not great, it can absorb the ups and downs of the road through the part with low elasticity coefficient to ensure comfortable ride.
5, linear spring, linear spring from top to bottom thickness, density unchanged, the elastic coefficient is a fixed value
