According to the nature of the force, the spring can be divided
into extension springs, compression springs, torsion spring and the
bending spring, according to the shape can be divided into disc
shaped spring, spring ring, a plate spring, helical spring, conical
spiral spring and torsion bar spring and so on, according to the
production process can be divided for cold rolled coil spring and
hot spring roll. Ordinary cylindrical spring due to the
manufacturing is simple, and can be made according to the load of
various types, the structure is simple, it is the most widely used.
Spring manufacturing materials generally should have high elastic
limit, fatigue limit, impact toughness and good heat treatment
performance, etc., commonly used carbon spring steel, alloy spring
steel, stainless steel and copper alloy, nickel alloy and rubber,
etc.. Manufacturing method of spring cold roll and hot roll method.
Spring wire diameter less than 8 mm cold roll the general law,
greater than 8 mm by coil method. Some spring also forced or shot
peening after being produced, can improve the bearing capacity of
the spring.
According to the China spring manufacturing industry sales demand
and investment forecast analysis report [2] statistics, the spring
can be divided into the following 7 categories:
1, the coil spring is a torsion spring, is to bear the torsion
deformation of the spring, it is the work of the part is also
closely around the spiral. The end of the torsion spring is a
torsion arm of various shapes, rather than a hook.
2, the tension spring is to bear the axial tension coil spring.
When the load is not loaded, the tension spring between the ring
and the ring is generally not a gap.
3, a compression spring is under axial pressure of the coil spring,
the cross section of the material was round but also useful for
rectangular and multi strand steel rayon rolled, spring, generally
for pitch, compression spring shape: cylindrical, conical, convex
and concave and a small amount of non circular, compression spring
ring and the ring will have a certain gap, when subjected to
external load when the contraction of the spring deformation,
stored deformation energy.
4, torsion spring use leverage principle, through the material of
soft, toughness of the large elastic material distortion or
rotation, so that it has a great mechanical energy.
5, progressive type spring, this spring the thickness and density
of inconsistent design, the advantage is in low compression can
through the low elasticity of part absorbs the road of ups and
downs, ensure the ride comfort, when the pressure increases to a
certain extent after the thick part of the spring to support the
body, and the shortcomings of this spring is control feeling not
directly, but is less accurate.
6, a linear spring, a linear spring from top to bottom thickness,
density constant, elastic 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 better control of the driver\'s
vehicle, and more for the performance of the modified car and
competitive vehicles, of course, is the comfort of the impact.
7, the short spring short spring compared to the original factory
spring to a shorter, and more
Air spring
Air spring
Stout, installation short spring, can effectively reduce the center
of gravity of the body, reduce cornering roll, bends more stable
and smooth, improve vehicle corners manipulation. And the original
shock absorber damping set comfortable bias, so the short spring
and shock absorber factory in coordination is not very stable, it
can not be effective inhibition of short spring rebound and
compression, driving on the bumpy road, will have an unpleasant
feeling are jumping, unchecked, the service life of the shock
absorber will greatly shortened, and there is a potential leak. Of
course, these conditions are relatively speaking, the daily driving
will not be so serious damage, and try not to drive, after all, the
original shock absorber can not bear high load *
