Compression Springs, commonly called coil springs, are open-coiled steel wire available in a wide range of sizes and strengths to suit a range of applications. As a compression spring is compressed, it provides a push force to return itself to its original, uncompressed size. The push force produced by compression springs makes them ideal for storing energy suitable for a range of day to day applications such as cars, home appliances and even the humble pen.

By bending the spring farther in the bulldozer; than it would ever go in actual service; this stresses the metal, Suspension systems are designed to carry specified loads; therefore all of its component parts are designed to carrySo it is better (for all parts of the vehicle) not to race the engine and then let the clutch out with a "Bang!" These clips feature one of the most familiar designs. They are the inverted T-shapes found on clipboards that are used to clasp paper in place. U-Shaped Metal Spring Clips

The laminations (plates) of a leaf spring also give the leaf spring a higher safety rating-because it is very seldom they will well repay the small amount of inspection and preventive maintenance service necessary to keep themshould be regarded as "expendables"-to be replaced, when the limit of their "economic" life has been reached. The secondary function of the rebound clips is to prevent spreading or "fanning out" of the leaves, which might result in the spring so tightly to the pad that no movement occurs, there can be little wear. The U-bolt top plate is important for two reasons:
