Air Suspension System
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’.
AIR SUSPENSION OVER CONVENTIONAL SUSPENSION
The conventional metal springs faced some drawbacks which were air suspension system overcomes and so they are preferred and used in more these days.
1) The automatic control devices installed in the vehicle allows making optimum use of the variable space for deflection of wheel.
2) The height of the automobile remains steady and so the changes in the alignment of headlamp due to varying loads are restricted.
3) It helps to reduce the load while the vehicle in motion i.e. the dynamic loading as the spring rate variation between laden and unladen weight is much less.
4) It gives smooth and comfort ride of the vehicle
ROLE OF AIR SUSPENSION SYSTEM
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 passenger.
WORKING
The atmospheric air first passes through the filter where the dirt is removed and passed on to the compressor. Air is compressed here and the pressure of air is raised from atmospheric to about 250 Mpa. This pressure is maintained by the accumulator tank. The safety relief valve is provided on the accumulator as a safety device and it opens when the pressure rises above 250 Mpa. This air then moves to lift control valve and through leveling valves to te air springs.
