A bar of resilient metal wound into a spiral that may be compressed or extended without permanent deformation. Coil springs have many automotive applications but are particularly important as suspension springs and valve springs.
A thick steel wire that has been coiled and heat-treated to form a very strong spring. Commonly used in car and light truck suspension systems, coil springs are space-efficient and can vary in stiffness, even within the same spring (i.e., stiff at the top and not stiff at the bottom). The coil springs on a given vehicle largely define how that car or truck's ride and handling will feel.
A helical spring, mainly used in vehicles for reacting compressive loads that may be compressed or extended without permanent deformation. Coil springs are particularly important as suspension springs.
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.
