One of the important thing in safety is the suspension system. Suspension connects the body or chassis of the vehicle with the wheels.Function of the suspension is during running the suspension absorb various vibration,oscillation, and shock receive by the vehicle. Suspension also transmits the driving and braking forces,improve driving stability and support body on the axles.It consists of the following principal components such as springs that neutralize the shocks from the road surface, shock absorbers(dampers) acts to improve riding comfortby limiting the free oscillation of the spring, stabilizer(sway bar or anti-roll bar)prevent lateral swaying of the vehicle, a lingkage acts to hold the above components in place and to control the longitudinal and lateral movement of the wheels.
