A Coil spring, also known as a helical spring, is a mechanical device, which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded. A material is said to be elastic if it deforms under stress (e A helix (pl helixes or helices) from the Greek word έλιξ, is a special kind of Space curve, i
Coil springs are a special type of torsion spring, the material of the spring acts in torsion when the spring is compressed or extended. A torsion spring is a spring that works by torsion or twisting that is a flexible elastic object that stores Mechanical energy when it is twisted A spring is a flexible elastic object used to store mechanical Energy.
The two usual types of coil spring are:
- Tension coil springs which are designed to resist stretching. They usually have a hook or eye form at each end for attachment.
- Compression coil springs are designed to resist being compressed. A typical use for compression coil springs is in car suspension systems. Suspension is the term given to the system of springs, Shock absorbers and linkages that connects a Vehicle to its Wheels Suspension
Metal coil springs are made by winding a wire around a shaped former - a cylinder is used to form cylindrical coil springs.
Many types of coil spring are wound in an annealed (soft) condition and then tempered to achieve their strength as a spring. Annealing, in Metallurgy and Materials science, is a Heat treatment wherein a material is altered causing changes in its properties such as strength Tempering is a Heat treatment technique for metals and Alloys In Steels tempering is done to "toughen" the metal by transforming brittle Over time, this tempering can be lost and the spring will sag because it can no longer withstand the loads applied. Such springs can be re-set by annealing, returning to their original length (or deliberately setting them to a different length) and then re-tempering. Damage to springs, such as using oxy-acetylene to cut the end off a car suspension spring to lower a vehicle's ride height, can destroy the tempering in localised areas of the spring. Concerning a.
