Which kinds of suspension springs are there

Automobile suspension springs generally have carbon spring steel, manganese steel, silicon manganese steel and so on.Carbon spring steel is less used in the automobile because of its low hardenability, and manganese steel has good hardenability, but it is easy to produce quenching crack and temper brittleness.Silicon-manganese steel is widely used in China.Spring shock absorber is mainly used to suppress the shock of spring aftershock absorption and the impact from the road surface.In the rough road, although the shock absorber spring can filter the vibration of the road surface, the spring itself will also have reciprocating motion, and the spring shock absorber is used to suppress this spring jump.

Spring shock absorber too soft, the body will jump up and down, spring shock absorber too hard will bring too much resistance, hampering spring normal operation.In the modification process of the suspension system, the hard spring shock absorber should match with the hard spring, and the hardness of the spring is closely related to the machine weight, so the heavier machine generally adopts the harder spring shock absorber.In order to design the best combination scheme of spring shock absorber and spring, it is necessary to try again and again.
