The suspension system of a vehicle plays an important role in providing a smooth and comfortable ride. It consists of components such as springs, shock absorbers, and links that connect the wheel to the chassis frame. The suspension helps reduce the impact of bumps or irregularities on the road surface by absorbing some of the force before it reaches the passenger area. The suspension also improves handling by maintaining the contact between the tyres and road surface. This allows for better grip when turning corners or taking evasive action in an emergency situation.
