Today every kind of machine has a vital requirement of springs. Coil springs are one of the most trusted materials when the matter comes to providing support, balance and stability. Car is among those machineries that need coil springs for its smooth operation. With the help of these springs a four wheeler can gain ability to get stable in zig zag and harsh roads. Most vehicles use coil springs for attaining stability. Helical spring also called as a coil springs is a device that stores energy and releases it whenever required. This spring is also used for extra purposes like absorption of shocks and maintaining force between two surfaces that contact with each other. To fulfill these activities with perfection a coil spring is made of elastic material in helix shape. This shape goes back to its original length during the release of stored energy.
Basically two types of coil springs are used now days. First one is known as tension coil spring. It is especially created to withstand excessive stretching. This kind of spring usually has a hook at the end. This hook is utilized as an attachment. The second kind of compression coil springs is created to withstand compression. These springs are used in the suspension system of a vehicle. The coil spring actually works in combination and coordination with the shock absorber of the vehicle to deliver the required performance. Coil springs stretch and compress to provide stability to the vehicle. The shock absorber reduces the effects of bumps and vibrations that are absorbed by the vehicle on the road.
