DESCRIPTION

AIR SPRING:

Air spring is a rubber bellow containing pressurized compressed air with an emergency rubber spring providing various suspensions characteristic to maintain a constant buffer height irrespective of the loaded condition.

The necessity for Introducing Air Spring in Hybrid Coaches:

Due to the Super-Dense Crush Load, the bolster springs become solid, which in-turn damages/breaks the coil spring resulting in discomfort to the passenger. So to overcome the above problem on air suspension (air spring) is introduced in the secondary suspension to maintain a constant buffer height irrespective of the loaded condition by varying the pressure of air inside the air spring.

Working Principle:

With changing loads, air spring reacts initially by changing the distance between air spring support and coach body. then actuating height monitoring valve( leveling valve ), either by taking the compressed air to the air spring or releasing air pressure from it to the atmosphere this process continues until the required height is maintained this mechanism ensures a constant floor height on coaches provided with air springs, irrespective of the load.

The Main Components of Air Spring are as under:

Bellows
Lateral shock absorbers
Level equalizing valve lever
Branch pipe 20dia.
Inner side emergency spring
150 litres capacity reservoir.
40 litres capacity auxiliary reservoir- 04nos.
Non-return valve
Isolating cock
Duplex check valve
Air spring support cradle
Air spring releasing valve
