Principle of Suspension System

1.  There is a need of a flexible connection between the main frame and the wheels of the vehicle in dynamic condition that enables the relative motion between them without causing deformation to the main structure or any other components of the vehicle.

2.  A suspension system in a vehicle is needed to support the overall weight of the main frame that includes the weight of the all mounted components along with the passenger’s weight.

3.   A vehicle needs a suspension system to maintain the firm contact between the tires and the road which in turn provide stability to the vehicle

4.  When a vehicle takes sharp turn there is the tendency of the frame to roll along its lateral axis which should be prevented in order to prevent the vehicle from rolling so a suspension system is needed in a vehicle that can prevent the vehicle from excess rolling.

5.  When the vehicle accelerates from its initial state and when the brakes are applied in both these conditions there is a tendency of the frame to roll along its longitudinal axis due to which the wheels of the vehicle tries to lose contact with the road surface, so a suspension system is needed in a vehicle that can prevent the vehicle from excess rolling along its longitudinal axis.
