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.

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.

Air Shock:

An air shock is a type of overlade shock absorber that can be inflated with air to increase the suspension’s load carrying ability.

Advantages of Air Suspension Shock Absorber

1. Ideal axle height

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 position.

2. Improve driving dynamics, road handling and comfort

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 and lower resonance frequency

Better sound isolation of airbag and lower resonance frequency, which leads to a smoother and more comfortable ride.

4. Absorber energy

Higher ability to absorb energy which means better and safer handling in extreme driving conditions.

Maintenance of the air shocks, Vehicle Check-List

•  Check the air lines and devices of leakage and that they turns freely.
•  Check the bellows bearing for damage, correct fastening, deformation, sharp edges.
•  Check the shock absorbers for operation and impermeability as well as tightness and bearing.
•  Periodically, check nuts and bolts for proper torque. For specific recommendations see manufacturer's manual.
•  Check axle suspension, trailing arms and rods for wear. 
•  Check height control valve to see that it is functioning properly. A properly maintained valve will save unneeded maintenance expense.
•  Routine inspection of all of the above according to manufacturer's instructions, will extend the life of your vehicle and reduce your overall maintenance expense.
