Air brakes are responsible for parking an 18-wheeled vehicle on the road. You can more clearly understand about this by looking at truck air brake system diagram. They are also responsible for parking buses, other trucks and vans. A safer system, designed for use by trains by George Westinghouse, was patented by George Westinghouse in 1872.
The first air brakes were designed for use on trains. They are also used for many trains, but are now more common for large vehicles. Westinghouse initially broadened its design and developed a variety of automatic shutoffs. As they became automatic, the use of air brakes continued on the highway.
The trucks use a “compressed air brake system”. Other types of air brakes include standard disc / drum brakes which use compressed air instead of hydraulic fluid. Although the use of disc brakes on trucks is increasing, most pneumatic truck brake pads are drums.
Compressed air brake systems work by sucking air filters into the air, compressing the air, and storing it in a high pressure reservoir. When this air is needed for the collision, the lower air is sent to the brake working cylinder. The cylinder applies the brakes and pulls the vehicle to a slow stop.
The compressed air brake system is divided into two parts: the equipment and the control. Electrical equipment provides high pressure for the compression, storage and control system. The equipment also transmits air to other air conditioning systems such as gearshift control, air assisted clutch pedal servos, etc. Orders are also divided into two cycles: parking and parking. The double brake circuit is divided into the front wheel and the rear wheel. This circuit receives air from a separate tank for added safety during a thunderstorm. The braking program is used by compressing the pneumatic valve of the brake pedal. This controls two cycles. The brake pedal is a machine that operates the air spring which is applied by spring force through the spring brake cylinder and released by compressed air by the control hand.
Trailer brakes have two straight lines. A control line or service isolation of the equipment. The delivery lines receive air from several sources. A command line or service can control the air flow to the trailer brakes.
