Facts about Air Brake Systems

Driving a commercial vehicle requires meticulous attention to its complex system of mechanics, a significant part of which is the Air Brake System.

Understanding how air brakes work is not only vital to safety and efficient operation, but also to advancing a driving career. Welcome to our comprehensive guide on the Air Brake System.

Understanding the Basics of the Air Brake System

The concept of the air brake system, also known as compressed air brake system, was first patented by George Westinghouse in 1869. Since then, it has revolutionized railway transport and has also become a key element in heavy vehicles such as trucks and buses.

The essence of the air brake system lies in its name – it uses _air_ as its operating force. In simple terms, the system converts the air pressure into mechanical force which helps the vehicle to stop or slow down.

Components of the Air Brake System

Understanding the complexity of the air brake system starts with familiarizing oneself with its integral components. The primary components include:

The Compressor

The compressor plays a critical role in generating the air pressure needed for the braking action. It intakes atmospheric air, compresses it, and then delivers it to the air reservoir.

The Air Reservoir

Once the compressor delivers the pressurized air, it is stored in the reservoir. The air reservoir, also known as the air tank, maintains a reserve of compressed air which is readily accessible when required for braking.

The Brake Valve

The Brake Valve, or the feed valve, serves to regulate the flow of air to the brakes. By controlling the valve, the operator determines when and how much compressed air reaches the brakes.

The Brake Chamber

The Brake Chamber is the component where the essential transformation happens. It converts the air pressure from the system into mechanical force that acts on the brake pads, resulting in the slowing or stopping of the vehicle.

How the Air Brake System Works

Understanding the operation of the air brake system encompasses three stages:

1. Charging: The compressor generates air pressure and sends it to the reservoir. This pressurized air is stored for future use.

2. Application: When the brakes are applied, the brake valve regulates the flow of the pressurized air from the reservoir to the brake chambers.

3. Release: When the brakes are released, the excess air in the brake chambers is evacuated, permitting the brake springs to retract and subsequently release the brakes.

Safety Measures in Air Brake Systems

Safety should never be compromised while operating vehicles, especially those equipped with air brake systems. Here are a few crucial safety considerations:

– Regular inspection and maintenance of the system.
– Ensuring the air pressure is within the recommended levels.
– Regularly checking the condition and effectiveness of brake pads.

Air brake systems have proven to be reliable and efficient over many decades. Their understanding and proper usage can go a long way in ensuring safety on the roads.
