Shock Absorbers
The suspension system protects the vehicle and the driver from the forces sustained while driving and improves safety by enhancing handling. The primary components of a suspension system are the springs and shock absorbers. The springs resist the vertical movement of the wheels to keep it in constant contact with the ground. The more rigid the spring, the better it is at carrying loads and keeping the vehicle grounded which is essential for god vehicle handling. Some special springs like springs for a bus have good load-bearing capacity without sacrificing so much of ride comfort.
The shock absorbers are the components of suspension systems that are responsible for ride comfort. The shock absorbers dampen or soften the vertical motion brought on by driving the vehicle on a rough surface. If a vehicle only had springs, it would flounder about and keep on rocking to the point that the driver and passengers get seasick and have to get off. The shock absorbers have two primary functions. Aside from improving comfort and protecting the car and driver from vibrations, the shock absorbers work in conjunction with the springs to keep the vehicles attached to the road. The springs allow the wheels to move and down, following the physical characteristics of the road. If a wheel encounters a bump, the kinetic energy of that moving unsprung mass is sent to the shock absorbers where it is dissipated by forcing gas or oil through a constriction valve. There are shock absorbers with an adjustable constriction valve that allows drivers to control the dampening effect of the suspension component.
