Different Kinds Of Suspension Systems

What is suspension system in vehicles? Basically, the system is composed of mechanical linkages, dampers as well as springs that are responsible in connecting chassis to the wheels of the car. The suspension systems have two major roles in the vehicle’s operation. The first is that it helps control how the vehicle is handled and second, it controls the brake in order to maintain safety and to ensure the comfort of the passengers despite vibrations, bumps and other forces.

One of the purposes of suspension system is to keep the vehicle at a certain height and to make sure that alignment of the wheels is correct. The vehicle’s direction is also impacted by the suspension system and it maintains the perpendicular direction of the wheels to retain the highest grip possible. The suspension also keeps the vehicle from being damaged aside from the usual wear and tear. It is common to see a single car with different designs of suspension on the front as well as the rear.

There are three types of suspension system – the independent, dependent and semi-independent.

Independent suspension system. In this type of system, the right wheel and the left wheel are independent of each other. Therefore, they are free to move vertically if the surface is not even. If there is a force impacting one wheel, the other wheel will not be affected as there is no direct connection between the two. Majority of the vehicle’s independent suspension system is installed on the front wheels.

Independent suspension system. It is the opposite of independent suspension because the two wheels have a connection in this case. If one wheel is moving because of uneven surface, the other wheel’s motions will be affected as well. This type of system is usually installed in heavy vehicles.

Semi-independent system. This is a combination of the first two suspension systems but this is accomplished by installing twisting suspension parts. The best example of a semi-independent system is a twist beam. The movement of the wheels are relative but the changes on the position of the first wheel has also some impact on the second wheel.
