The document discusses an automatic air suspension system for vehicles. It provides an introduction to air suspension systems and their role in supporting a vehicle's weight while providing a smoother ride. The key components of an air suspension system are the air supply, air bags, and height control valves. It works by using air bags made of rubber and plastic that are inflated or deflated to adjust the vehicle's height and maintain a level position. The advantages listed are excellent suspension and comfort, fully automatic level control, good handling, protection of the vehicle from damage, keeping tires firmly pressed to the ground, and increasing the life of the vehicle.

4. INTRODUCTION
‘The automatic air suspension system is an air-operated,
microprocessor controlled suspension system.
This system replaces the conventional coil spring suspension and
provides automatic front and rear load leveling. The air bags,
made of rubber and plastic, support the vehicle load at the front
and rear wheels’
Sir William Brush is the father of suspension system in
automobiles

5. ROLE OF AIR
SUSPENSION SYSTEM
 The main role of air suspension system are as follows:
 A . It supports the weight of vehicle.
 B . Provides smoother ride for the driver and passengers i.e. acts as cushion .
 C . Protects your vehicle from damage and wear.
 D . It also plays a critical role in maintaining self driving conditions.
 E . It also keeps the wheels pressed firmly to the ground for traction
 F . It isolates the body from road shocks and vibrations which would otherwise be
transferred to the passengers and load

6. PRINCIPLE OF AIR
SUSPENSION
Principle :- When a tire hits an obstruction, there is a reaction force. The
size of the reaction force depends on the unsprung mass at each wheel
assembly.
in general, the larger the ratio of sprung weight to unsprung
weight, the less the body and vechicles occupants are affected by pumps,
dips, and other surface imperfections such as small bridges. A large sprung
weight to unsprung weight ratio can also impact vehicle control.

7. COMPONENTS OF AIR

suspension system .
A . The air supply
B . Air bags
C . Height control valves

15. ADVANTAGES
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 & Levering Function
Increase life of vehicle

16. CONCLUSION
From the whole discussion in suspension system, I observe that
suspension system is like a white blood cell As white blood cell . As
white blood cell provides energy to body to fight against diseases or
viruses which try to destroy or try to decrease our life , in similar way
SUSPANSION SYSTEM provides the energy to a vehicle to protect
itself from damaging, increasing life of the vehicle , increase the
handling , increase the 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 only
diffrence is speed .
So, The Scope Of The Suspension System is Too Bright.
