Definition
A coil 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 coil spring is a crucial component in your car's suspension system. Made from strong metal, a coil spring compresses itself to absorb the shock caused by bumps in the road as you drive along. Coil springs support the weight of the vehicle and react to road irregularities. When parked, the weight of the vehicle and occupants compress the coil springs a certain amount to maintain a predetermined ride height. On the road, when a bump forces a wheel upward, the spring compresses further, allowing the vehicle to remain level and isolating the passengers from the impact. After the bump, the spring forces the wheel downward to maintain road contact.
Background
Car Coil springs are made with wide gap coils that compress to absorb impact when tires roll over rough terrain. In most vehicles you’ll find springs, shocks and struts working together like an inseparable team, with the struts physically supporting the springs together, and shocks working with springs to stop your car from bouncing up and down forever. In addition to improving ride quality by reducing bounce, coil springs and struts are also a critical component that gives the car its height and keeps it off the ground. Remove the struts and springs and your car will drop unsafely low to the ground.
Purpose
A coil spring (also called helical spring) is a kind of torsion spring which can store energy and release it later when needed. It can also absorb shock and maintain the force between two contacting surfaces. Together with a shock absorber, coil springs are pre-assembled as one coil over unit before installation. While the coil spring compresses and stretches to keep you safe as you drive, the shock absorber keeps you from road noise, bumps, and vibrations that you might encounter while doing so. All in all, a coil over is essential in your vehicle's suspension because it gives you optimal damping, good handling and braking, and a comfortable ride all at the same time.
You Should Know
One of the indispensable parts of the suspension system is the coil spring. This suspension part is actually a helically-shaped steel bar that absorbs the shock resulting from the tires' contact with the road. When your vehicle's front wheels run over a bump or a pothole, the coil spring compresses and absorbs the impact. As soon as the road becomes even again, the spring releases the energy and returns to its original state. Because of this shock-absorbing function, your vehicle's coil springs are usually built to be tough and damage-resistant. Some coil springs are even vinyl-coated for corrosion resistance and noise reduction. However, several conditions such as frequent vehicle overloading, fatigue, and overuse may leave your vehicle's coil springs weak and brittle.
