Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.
In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. [1] When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. [2]
Brake Tests Cold Performance Equivalence and Speed Sensitivity Tests For the tests the vehicle brake for which the replacement linings are designed is installed in an inertia dynamometer instrumented for continuous recording of rotative speed, brake torque, brake line pressure, number of rotations after brake application, braking time, and ...
A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle ...
Westinghouse Air Brake Company's Rotair Valve [18] The first form of the air brake consisted of an air pump, a main reservoir (pressure vessel), and an engineer's valve on the locomotive, and of a train pipe and brake cylinder on each car. One problem with this first form of the air brake was that braking was applied to the first cars in a ...
