What is Air Brake System Drivers rely heavily on their brakes when hauling thousands of pounds in trucks. The braking device on massive vans, buses, and tractor-trailers consists of air brakes. Trailer Air Brake System Diagram Air-operated brakes are a safer option on larger vehicles as hydraulic fluid can leak and cause an accident. As a friction brake, an air brake uses compressed air in a piston to apply pressure to the brake pad or brake shoe needed to stop the vehicle. Understanding the air brake system diagram is essential for maintenance. Air brakes are used on large, heavy vehicles, especially those with multiple trailers that need to be connected to the brake system. In 1872, George Westinghouse developed the first safe air brake for use in railway service. Trailer air brake system diagram He made several modifications to improve the invention of the air-pressure brake, which led to the development of various automatic brakes. Being an important part of diesel vehicles, you need to know how air brakes work and what the parts are and how to maintain the air brake system. So let’s begin. Component Trailer air brake system diagram The main components of an The air brake system diagram illustrates the key components and their connections are: Air compressor Storage tank Brake pedal Brake drum Safety valve Brake lining Dirt collector Brake actuator Triple valve Air filter or dryer 1 Air Compressor An air compressor helps draw atmospheric air into a storage tank or reservoir. Trailer Air Brake System Diagram It compresses the air to the preferred pressure and transfers it to the storage tank. An air compressor is driven by an engine using a belt drive. An air brake system diagram helps in diagnosing brake issues. A compressor can be air-cooled or cooled by an engine cooling system. 2 Storage tank The purpose of the storage tank is to safely store the compressed air delivered by the compressor. Mechanics often refer to an air brake system diagram during repairs. It is an essential part of the air brake system as the compressed air is responsible for proper operation. This stores enough air to allow multiple braking when the engine stalls or the compressor fails. Trailer air brake system diagram In a vehicle, the size and number of reservoirs depends on how many brake chambers and their sizes there are, as well as how the parking brake is configured. 3 Brake Pedal The air brake system is actuated by driver input. The brake pedal is the number one part that activates the brakes to stop or sluggish down the car. It is a type of mechanical coupling that converts input motion into forward motion. Trailer air brake system diagram As a result of pressing the brakes, compressed air is forced into the tire, which stops the vehicle. 4 Brake drum The brake drum is the only part of the system that performs the braking process. Trailer air brake system diagram When the vehicle stops or slows down, the brake force is transferred to the wheels by the The air brake system diagram includes the air compressor and reservoirs. brake drum in the form of friction between the brake pads and the drum lining. The outer part of the brake drum consists of the drum lining which rotates with the wheel, and the inner part which contains the brake shoe rests when the brake pedal is not depressed. Generally, brake drum is used in air brake system but with proper arrangement. 5 Safety valve A safety valve is usually installed in the storage tank, near the compressor. A safety valve prevents the storage tank from over-pressurizing as the compressor continues to work to supply air. It has a spring-loaded ball that allows air to escape from the reservoir to the atmosphere. Trailer air brake system diagram When the air pressure reaches a certain value, the safety valves release the air. 6 Foot Valve The function of the foot valve can to attract compressed air from the reservoir whilst the brakes can implemented. Trailer air brake system diagram The amount of air supplied to the brakes can controlled by the driver according to the distance to the treadle or brake pedal. By rotating the foot valve treadle, the actuator controls the amount of air pressure applied, Analyzing the air brake system diagram can improve troubleshooting efficiency. but the maximum pressure must not exceed that in the reservoir. 7 Brake Lining These can called supply lines. The transfer of compressed air from the reservoir to the brake drum can accomplished by breaking the brake lines that connect the reservoir to the brake drum. 8 Dirt collection A dirt collector can generally positioned inside the brake line and department pipe. The air brake system diagram shows how air flows through the system It collects the dust debris separated by way of the air filter. This helps separate dust from the compressed air coming through the brake hose so that only clean air can enter the valve and reservoir. 9 Brake Actuator A brake actuator is a device consisting of a piston-cylinder arrangement directly connected to the brake pedal. Trailer air brake system diagram When the driver presses the pedal, it applies pressure to the entire assembly. 10 Triple Valve The triple valve can an important part of the air brake system. It can used to apply and release brakes, which requires a continuous application and release mechanism. Safety valves are clearly marked in an air brake system diagram. It applies pressure as soon as the pedal can  pressed, while releasing pressure immediately after the pedal can released. 11. Air filter and dryer As the name suggests, air filters remove dust particles from the ambient air, while the dryer input removes moisture and humidity. If the air brake system doesn’t have a dryer, it causes water condensation and air build-up in the lines, and in cold weather that condensed water can cause brake failure.
