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.
Shock absorbers and how they work
The shock absorbers reduce and slow down the vibrations from the
springs, which is why technically they are correctly referred to as
vibration dampers. Vibration dampers convert kinetic energy into
thermal energy through fluid friction. This involves the flow of
oil being slowed down by the valve passages inside the damper.
An air shock is a type of overlade shock absorber that can be
inflated with air to increase the suspension’s load carrying
Advantages of Air Suspension Shock Absorber
1. The car can be kept on its ideal axle height independent of its
variable load. Driving safety is improved due to better road
handling, for example, at night keeping the same headlight
2. Driving dynamics, road handling and comfort are improved. The
suspension is soft and comfortable during slow driving and becomes
noticeably stiffer during faster driving. The suspension responds
to dynamic load as it reacts to live load.
3. Better sound isolation of airbag and lower resonance frequency,
which leads to a smoother and more comfortable ride.
4. Higher ability to absorb energy which means better and safer
handling in extreme driving conditions.
