Air brakes in automobiles work on Pascals principle what about air brakes collect information about the working process of air brakes
Answers
Answer:
AIR BRAKES:
Air brakes are used in trucks, buses, trailers and semi-trailers. This is the preferred type of braking system for these vehicles for several reasons. First, the use of air allows multiple vehicle units to be coupled so that all units have braking capability and so that all of those units' brakes may be controlled from the cab. Coupling would be infeasible if a liquid were used as the mode of transmission of force, as it is in hydraulic brakes. In addition, the use of an air brake system allows for the incorporation of an emergency braking system that utilizes parts of the service brake and parking brake systems. Emergency braking systems are required on all semi-trailers by CFR 49 393.43, as it states "Every motor vehicle, if used to tow a trailer equipped with brakes, shall be equipped with a means for providing that in the case of a breakaway of the trailer, the service brakes on the towing vehicle will be capable of stopping the towing vehicle."
Air brake systems are three braking systems combined:
The service brake system applies and releases the brakes when one uses the brake pedal during normal driving.
The parking brake system applies and releases the parking brakes when one uses the parking brake control.
The emergency brake system uses parts of the service and parking brake systems to stop the vehicle in the event of a brake system failure.
The air brake system:
An air brake system uses air as a way to transmit pressure from the driver's control to the service brake. It also includes an air-over-hydraulic brake system.
