3. OUTLINE Introduction Role of air suspension system Principle of air suspension system Components of air suspension system Types of air suspension Advantages Conclusion

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 There are three fundamental components of air suspension system . A . The air supply B . Air bags C . Height control valves

10. HEIGHT CONTROL VALVE

11. WORKING OF AIR SUSPENSION SYSTEM

12. FIGURES SHOW DIFFRENCE BETWEEN INDEPENDEND AND NON INDIPENDEND SUSPENSIONES

13. 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

14. 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.
