Car suspension system: What does it do?

A car suspension system is one of the most critical parts of a car. It often goes unnoticed as it is silent in operation. But without a suspension, it’s hard to imagine driving a car. So, what is the use of a suspension system in a car?
The primary role of the suspension system in an automobile is to keep the car stable by negating the external forces. Here, external forces are nothing but the forces felt by the car's body due to potholes, bumps, etc., on the road. Also, the suspension keeps the car stable in corners and at high speeds and delivers superior handling.
To make it even simpler, let's put it this way. A suspension system absorbs the bumps which we usually find on roads. If there is no suspension to absorb these bumps, the tyres may lose contact with the road, and you may lose control of the vehicle. Similarly, if there is a dip in the road, the suspension extends and ensures that the tyres are in contact with the road. To sum it up, the suspension maintains the stability of the car and also cushions the cabin.
What is a car suspension?
So, coming to the heart of the matter, what is suspension in a car? In simple words, it is a component of a car that cushions the forces that a vehicle goes through while driving on the road.
The suspension cushions the cabin from the external forces felt due to small stones/rocks on the road, bumps/speed breakers or small/big potholes. Apart from negating the external forces, a suspension is also responsible for the stable handling of a vehicle. Without a suspension system, it may be impossible to drive a car.
How does a car suspension work?
Refer to the points below to understand how a car suspension works.
  • A car suspension works on the principle of force dissipation.
  • It involves converting the force into heat and thus, negating the impact on the car’s body.
  • The suspension system uses components such as springs, shock absorbers and struts to achieve the damping effect.
