Suspension System


The suspension connects the body of the vehicle with the wheels, and carries out the following functions:

1.During running, it acts, together with the tires, to absorb and damp the various vibrations, oscillations, and shocks received by the vehicle due to irregularities in the surface of the road, in order to protect the passengers and cargo, and improve driving stability.

2.It transmits the driving and braking forces, which are generated due to friction between the road surface and the wheels, to the chassis and body.

3.It supports the body on the axles and maintains the proper geometrical relationship between the body and wheels. It consists of the following principal components:

(1) Springs Neutralize the shocks from the road surface.

(2) Shock absorbers (dampers) Acts to improve riding comfort by limiting the free oscillation of the springs.

(3) Stabilizer (sway bar or anti-roll bar) Prevents lateral swaying of the vehicle.

(4) A linkage Acts to hold the above components in place and to control the longitudinal and lateral movements of the wheels.
