In general, it seems that the suspension of the car has one task – to make the ride smoother, helping to glide over bumps and uneven sections of the road. However, the car’s suspension system has a wide range of functions and is subject to enormous loads compared to other major systems.

How does the suspension system work?

Currently, most cars are equipped with independent suspension front and rear, so each wheel is able to move independently. Some cars use a more basic beam axis due to lower costs and simple construction. The only girder bridges that are still used in new cars are driving bridges. Dead axles have freely rotating tires, and drive axles have a drive wheel at each end respectively. But the rear tires, which do not move independently, always maintain the same angle relative to each other, and not relative to the road surface, so traction and predictability in driving are less.

Let’s find out what the front and rear suspension does:

• An independent front suspension allows each front wheel to be moved up and down with a spring and shock absorber bolted to the frame at one end, and a control lever or wishbone at the other end. The position of each component is critical, as the front wheels must maneuver and maintain constant alignment for safe vehicle operation.

• The independent rear suspension works based on the same concept as the front, excluding steering dynamics, since the rear wheels usually do not turn. All-wheel drive and rear-wheel drive cars come with a differential mounted on the frame in the middle of the control levers or wishbones. Cars with front-wheel drive have a simple rear suspension that requires only springs and shock absorbers.

What Is The Function Of Shock Absorbers & Springs In The Suspension?

Springs and shock absorbers provide excellent cushioning and compression when moving the suspension. The first gives the necessary strength to keep the sprung weight from the wheels and withstand compression, while the latter consists of oil-filled cylinders that cause the suspension to compress and expand at a constant speed so that the springs do not bounce down.

They essentially protect cars when faced with bumps in the road. Small cars typically use MacPherson struts, which are located in the center of the coil spring and act as shock absorbers. When the ride is comfortable, you can be sure that the suspension has excellent road insulation, which means that it can move up and down without causing shocks in the car.
