What are the types of steel wire springs?

Springs can be divided into seven categories:

1, spiral spring, namely torsion spring, is a spring that bears torsion deformation, and its working part is also densely wound into a spiral. Torsion spring end structure is machined into various shapes of torsion arm, rather than a hook.

2. The stretch spring is a helical spring that bears the axial tension. When not under load, the stretch spring between the ring and the ring are generally tight and no gap.

3, compression spring is to bear the axial pressure of the helical spring, it is used in the material section is more circular, but also useful rectangular and multiple strands of steel entangle winding, the spring is generally equal pitch, compression spring shape: Cylindrical, conical, convex and concave 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 subjected to external load, the spring contraction deformation, deformation energy storage.

4. 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.

5, progressive spring, this kind of spring adopts the design of thickness and density inconsistency, the benefit is that when the pressure is not large, it can absorb the ups and downs of the road through the lower part of the elastic coefficient, to ensure the comfort of riding, when the pressure increases to a certain extent, the thicker part of the spring plays the role of supporting the body, and the disadvantage of this kind of spring is that the control feeling is not direct, and the accuracy is poor.

6, linear spring, linear spring from top to bottom thickness, density unchanged, elastic coefficient for a fixed value. This design of the spring can make the vehicle to obtain a more stable and linear dynamic response, is beneficial to the driver better control of the vehicle, more used for performance oriented modified cars and competitive vehicles, the disadvantage of course is that the comfort is affected.
