Introduction

Air brake

Components of air braking system

Design of service brakes –this type of breaking is generally used for slowing or stopping of the heavy load vehicles. The function of service in heavy vehicles is quite simple. in this system , the break pedal is pushed, as a result of which the is routed at pressure of approximate 700 kPa and transfer to the brake chamber as a result of  which brake engaged and its function starts working.

Parts of design system

• supply system
• controls system

• the parking brake
• the trailing brake circuit

1. front wheel circuits
2. rear wheel circuits

The spring force of the spring brake cylinder is responsible for operating of the parking brake.

The function of trailer brake circuit- the main component of the trailer brake is based on the two line system:

• the supply line – the man function of the supply line is to receive the air from the prime mover parking braking system
• The control line- the control line is worked with the help of trailer brake relay valve.

Advantages of air brake system are

• Air brakes are generally used on the lighter vehicle like automotive industry, manufacturing industry etc. They are also used as hydraulic brakes because they are generally working the process that are movable ex- air brake, fluid braking.
   
• The braking system is never fail either if they are used on fluids to work like hydraulic brakes due to continuous or unlimited supply of air. little amount of leaks does not cause much more effect on the operation process as well as its function during the time of its scarcityand the fail of system is also minimized also.
   
• Hydraulic line cannot be easy to attach therefor Air line couplings are used which is quite helpful in attaching as well as DE attaching. Some other advantages are that they are quite safer than hydraulic line whenever there is danger of letting air in a pneumatic circuit .this factor is very much helpful in reducing the training of operator so reduce the cost also.
   
• Air brake is quite helpful in controlling the forces that are applied on the system because air not only help in transmission of fluid but also helps in storing the potential energy of the system .it has to be noted that air brake system contain air tank so that the vehicle get also stopped if the compressor not able to work properly. So this is quite helpful in removing the excess pressure also so that system can work properly.
   
• Air brakesystem is design in suchway that leakage is minimized so that they have good factor of safety.

(a) The service brake system- such breaking system which comes into action    when the operation had occurred under normal condition

(b) The emergency breaking system-such a breaking system in which operation are performed suddenly so that powerful breaking system allows stopping of vehicle at a sudden instant and also protecting the life of the people by protecting them from sudden shock.
