2. Railway air brake - Wikipedia

   en.wikipedia.org/wiki/Railway_air_brake

   A comparatively simple brake linkage. In the air brake's simplest form, called the straight air system, compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train.

3. Westinghouse Air Brake Company - Wikipedia

   en.wikipedia.org/wiki/Westinghouse_Air_Brake_Company

   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 ...

4. Relay valve - Wikipedia

   en.wikipedia.org/wiki/Relay_valve

   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 ...

5. Air brake (road vehicle) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(road_vehicle)

   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.

6. Gladhand connector - Wikipedia

   en.wikipedia.org/wiki/Gladhand_connector

   A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars. [2] Gladhand connectors resemble a pair of "hands shaking" when interlocked, hence the name. [1]

7. New York Air Brake - Wikipedia

   en.wikipedia.org/wiki/New_York_Air_Brake

   New York Air Brake gauges to control a Rotair Valve Westinghouse Air brake [1] Westinghouse and New York Air Brake began development of a replacement for the venerable "K Brake" in 1929. The Great Depression slowed, but did not stop, development of the new brake and, in April 1932, New York Air Brake began construction of a 200-car test track ...

8. Haldex (company) - Wikipedia

   en.wikipedia.org/wiki/Haldex_(company)

   The Foundation Brake product line includes brake products for wheel ends such as disc brakes, brake adjusters for drum brakes and actuators. Air Controls comprises products that improve the safety and driving dynamics of the brake system, such as compressed air dryers, valves, ABS and EBS.

9. S-cam - Wikipedia

   en.wikipedia.org/wiki/S-cam

   It is normally powered by air, but hydraulic power can be used too. The S-cam foundation brake is being used in over 85% of vehicles in the U.S. that run with air brakes. [1] S-cam's are only used with drum brakes because the cam pushes on the brakes which rubs against the rotating drum, and thus slowing the vehicle. [2]
