Model of Air Brake System Manufacturer,Supplier and Exporter in India

Product Code : EL-AELE-9416
Jlab Export is a leading Model of Air Brake System Manufacturer,and suppliers in India

This sectioned model sets out the main parts of a vehicle air brake system so that students can look inside each one. It is made from original parts such as the air compressor, unloader valve, foot valve, booster, wheel assembly, air tank and control valve. The parts are cut open and mounted on a sturdy iron frame.

How Compressed Air Applies the Brakes

On a vehicle, the engine drives the compressor, which pumps air into the air tank. When the tank reaches its working pressure, the unloader valve stops the compressor from charging it further. Pressing the brake pedal opens the foot valve, and air from the tank flows to the booster at the wheel.

The booster turns that air pressure into a push on the brake linkage, and the shoes expand inside the drum. Releasing the pedal lets the foot valve exhaust the air, and the shoes pull back. Because the foot valve meters the air, a light press on the pedal gives a light brake.

Air Brake Lab Exercises for Students

Students can trace the air path on this model from compressor to air tank, foot valve and booster, then draw it as a circuit diagram. Looking into each sectioned part, they name the valves and pistons and explain what moves when the pedal is pressed and released.

To see the same parts in action, the class moves to the Model of Air Brake System (Working). There a motor drives the compressor and the foot brake works. For truck and trailer circuits, the Pneumatic Air Brake Trainer sets out heavy-duty components on two mobile stands.

Frequently Asked Questions

Why do heavy vehicles use air brakes instead of hydraulic brakes?
Compressed air gives the large braking force a heavy vehicle needs from a light pedal effort, and the engine-driven compressor keeps the supply topped up. Air lines also couple easily to a trailer.

What is brake lag in an air brake system?
It is the short delay between pressing the pedal and the brakes applying. Air has to flow from the tank through the foot valve and lines and fill the booster before the shoes move. The delay is longer than in hydraulic brakes, so drivers of air-braked vehicles allow for it.

What is the job of the foot valve?
The foot valve is the brake valve worked by the pedal. It meters air from the tank to the boosters in proportion to pedal travel, and it exhausts that air to atmosphere when the pedal is released.

How does this model differ from the working air brake model?
This model presents the original parts sectioned on an iron frame, for study of their insides. The working model adds a motor-driven compressor, working foot and hand brakes, and two front wheel assemblies with a sectioned drum.
