WHATISSUSPENSION ??

Suspension is the term given to the system

of springs, shock absorbers and linkages

that connects a vehicle to its wheels

The automatic air suspension system is an air-operated,

microprocessor controlled suspension system. This system

replaces the conventional coil spring suspension and providesautomatic front and rear load leveling. The air bags, made of

rubber and plastic, support the vehicle load at the front and

rear wheels.

SirWilliam Brush is the father of suspension system inautomobiles.

INTRODUCTION


5/19

The main role of air suspension system are as follows:It supports the weight of vehicle .

Provides smoother ride for the driver and

passengers i.e. acts as cushion.

Protects your vehicle from damage and wear .It also plays a critical role in maintaining self

driving conditions.

It also keeps the wheels pressed firmly to the

ground for traction .It isolates the body from road shocks and

vibrations which would otherwise be transferred

to the passengers and load.

PRINCIPLE OF AIR SUSPENSION

Principle :-When a tire hits an obstruction, there is a

reaction force. The size of this reaction force dependson theunsprung massat each wheel assembly.

In general, the larger the ratio of sprung

weight to unsprung weight,the less the body andvehicle occupants are affected by bumps, dips, and othersurface imperfections such as small bridges. A large

sprung weight to unsprung weight ratio can also impact

vehicle control.

COMPONENTS OF AIR SUSPENSION- There

are three fundamental components of air suspension

system .

The air supply

Air bags

Height control valves

AIRSUSPENSION

Comprises of compressor , supplying air to air tank

Pressure maintained 5.6 to 7 kg/sq.m

Air bags on each wheel

As load applied , air bags compressed actuating theleveling valve .

Air from the tank fills the compressed air bag &

hence raise the level of the frame.

Air from air bag gets released as load on chassisdecreases

ADVANTAGESOFAIRSUSPENSION

Excellent Suspension & Comfort to passengers

Fully Automatic Level Control

Good handling

Shields the vehicle from damage Keeps the tires pressed firmly to ground

Easy To Service

Lifting & Lowering Function

Increases life of vehicle

COMMON AIR SUSPENSION PROBLEMS

Air bag or air strut failure

- due to old age, or moisture within the air system that

damages them from the inside.

Compressor failure

- Primarily due to leaking air springs or air struts

- Compressor burnout may also be caused by moisture from

within the air system coming into contact with its electronic

parts.

Dryer failure

- which functions to remove moisture from the air systemeventually becomes saturated and unable to perform that

function

CONCLUSION

From the whole discussion in suspension system, I observe that

suspension system is like a white blood cell .As white blood cell

provides energy to our body to fight against diseases or viruses which

try to destroy or try to decrease our life ,in the similar waysuspensionsystem provides the energy to a vehicle to protect itself fromdamaging, increasing life of the vehicle ,increases the handling,

increases comfort of passengers and many more. So, according to me if you remove the suspension system, then you

feel like in bull- cart in Audi , Mercedes types luxurious cars. The onlydifference is speed. So, the scope of Suspension System is Too Bright.
