Suspension

The suspension is the link between the road and the car body. The job of the suspension is to reduce, as far as possible in a controlled fashion, the vibrations from the wheel and the car body caused by an uneven road or changes of direction. Every attempt must be made to prevent these vibrations from being transmitted to the car body in order to reduce rocking, pitching and diving, avoid swaying, and ensure optimum road contact and traction with minimum slip. The suspension system comprises a range of components, including strut support bearings, springs, shock absorbers, connecting rods (coupling rods), stabilisers, axle supports, wheel bearings, suspension arms (control arms and pull rods), wheel brakes, rims, tyres, final drives and steering.

How Air Suspension Works ?

In Place Of The Spring Is A Bellow (Usually Made From Rubber) Filled With Air . Under Load , The Bellow Is Compressed , Causing A Decrease In Volume And An Increase In Pressure . If More Air Is Pumped In , The Bellow Is Reinstated To Its Normal Volume Or , More Crucially , Its Normal Height .
