Presentation Transcript

Slide 1: 

1 AIR BRAKES SYSTEMS

AIR BRAKES : 

2 AIR BRAKES AIR BRAKES USE COMPRESSED AIR TO MAKE THEM WORK. YOU CAN APPLY ALL THE BRAKING FORCE YOU NEED TO EACH WHEEL OF A VEHICLE, EVEN TRACTORS PULLING TRAILERS. IF MAINTAINED AND USED PROPERLY THEY WILL SAFELY STOP LARGE VEHICLES.

Slide 3: 

DUAL AIR BRAKING SYSTEM: As its name suggests, the dual system is two systems or circuits in one. There are different ways of separating the two parts of the system. On a two–axle vehicle, one circuit operates the rear axle and the other circuit operates the front axle. If one circuit has a failure, the other circuit is isolated and will continue to operate.

Slide 4: 

BASIC TYPE: When a brake application is made, air is drawn from the primary reservoir through the foot valve and is passed on to the rear brake chambers. At the same time, air is also drawn from the secondary reservoir, passes through the foot valve and is passed on to the front brake chambers. If there is air loss in either circuit, the other will continue to operate independently. Unless air is lost in both circuits, the vehicle will continue to have braking ability.

Slide 5: 

DUAL BRKING SYSTEM WITH SPRING PARKING TECHNOLOGY: When spring brakes are added to a dual air brake system, the same type of dash control valve discussed previously is used. Blended air is used to supply the spring parking brake control valve (27). Blended air is air taken from the primary and secondary circuits through a two–way check valve (26). With this piping arrangement the vehicle can have a failure in either circuit without the spring brakes applying automatically. If air is lost in both circuits, the spring brakes will apply. 27 26

Slide 6: 

SPRING PARKING SYSTEM WITH MODULATOR VALVE : Spring parking brakes in this system serve two purposes: first, as a parking brake, and second as an emergency braking system. If a failure occurs in the primary circuit (green), and a brake application is made, control air from the foot valve is directed to a spring brake modulator valve (23). As there is no supply air to maintain balance in the modulator valve, because of the primary circuit failure, the modulator valve then exhausts air pressure from the spring parking brake circuit.

Slide 7: 

Combination Tractor and Trailer with Spring Parking Brakes The trailer system is supplied by blended tractor air taken from the primary and secondary circuits through a two–way check valve as previously described.
