How does a suspension system work?
Obviously suspension systems will vary greatly between makes and models, but most will consist of a chassis or frame, dampeners (including shock absorbers and struts), coil springs and leaf springs. Your vehicle’s suspension system is designed to give you complete driving control and a smooth, comfortable ride. As you accelerate, any bumps cause forward energy to be converted into vertical energy, which consequently travels through your vehicle’s chassis.
Coil and leaf springs absorb this vertical energy preventing your vehicle from jumping up off the road. Dampeners (shock absorbers and struts), then dissipate the energy absorbed by coil springs, so any vertical motion is quickly reduced to zero.
Effectively, this means if the dampeners are in good condition, you’ll barely notice the bumps in the road. However, if they’re worn, you and your passengers are in for an uncomfortable ride. For safety’s sake, the key thing to remember is to ensure your suspension system is in good working order.
