What is the role of leaf springs and shock absorbers?

leaf spring

The springs commonly used in large trucks have the advantages of heavy load, simple structure and low cost. The disadvantages are large weight, high stiffness, poor comfort, large space occupation, and low energy absorption rate. A large part of the energy of the bumps in the ride will still be transferred to the frame. Generally used in various trucks, cheap vans, etc.

coil spring

It is a common spring. The advantages are that it takes up less space, has a simple structure, is highly customizable, is light in weight, is more comfortable, and has a high energy absorption rate. The disadvantage is that the load capacity is smaller and the cost is higher than that of leaf springs. Strong customizability means that by changing the thickness and density of the spring, the spring has different elastic values under different compression strokes. Therefore, coil springs can be subdivided into progressive springs and linear springs. The progressive spring can make the spring have a low elasticity value in the initial stage of compression, which can filter most of the vibrations during driving, but at the end of the compression stage, the elasticity value becomes high, so that the frame can be supported enough without supporting the bottom. Therefore, coil springs are mostly used in passenger cars.
