Sitting into the car, the first thing that we pay attention is the smoothness of the suspension. The suspension of a modern car in 90% of cases is constructed using springs or hydro-pneumatic ammortizers. However, there is a category of cars that require increased load capacity and strength of the chassis. These are serious SUVs (jeeps) and cargo-passenger cars. In the design of these machines, a spring suspension is used.

What is the spring? Spring is an elastic vehicle pendant element that distributes the load of the frame or body body to the running bridges and an employee to mitigate the bodies and fluctuations in the body during the movement. It is the spring compensates for all oscillations and impressions caused by the defects of the road surface and provides proper comfort in the car's cabin.

Sproughts exist different types, but in civil engineering, sheet springs are most widely distributed. Spring sheet is a package of tempered spring steel sheets, further curved in the form of a sickle. This package in the center of the inflection is attached using special clamps to the car bridge, and the two free end of the springs are attached to the body or frame. Thus, the body suspension on the bridge is damping the elastic effect of the springs.

In modern automotive, the so-called semi-elliptic springs are used. However, some Western manufacturers also use torsion springs. They are distinguished by greater durability, compared with multi-lidly, however require increased attention when maintained. Also distinguish the front and rear springs.

The springs used in heavy SUVs and trucks are experiencing colossal loads during operation, therefore made from special steel varieties. Also quite often, the springs are enhanced by additional sheets, if required during operation.
Despite their age, the spring suspension did not heal. In some cases, without it, it's just not to do. And modern technologies and materials gave this design to the second life.
