The Westinghouse Air Brake Technologies Corporation (WABCO) was an American company founded on September 28, 1869 by George Westinghouse in Pittsburgh, Pennsylvania. [5] Earlier in the year he had invented the railway air brake in New York state.
1869: George Westinghouse receives patent for the air brake. Westinghouse Air Brake Company organized with George Westinghouse as president. 1872: Automatic air brake invented. 1878: First foreign air brake company started at Sevran, France. 1881: Westinghouse Machine Company formed. The Westinghouse Brake Company, Ltd., in London, England ...
A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [2] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's ...
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.
However, air brakes can be made much more effective than vacuum brakes for a given size of brake cylinder. An air brake compressor is usually capable of generating a pressure of 90 psi (620 kPa; 6.2 bar) vs only 15 psi (100 kPa; 1.0 bar) for vacuum. With a vacuum system, the maximum pressure differential is atmospheric pressure (14.7 psi or 101 ...
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]
The new designs are the last changes for the aviation industry more than 100 years after a set of siblings modernized air travel. ... Who invented the first successful airplane depends on how ...
In 1953, LeTourneau sold his entire earthmoving equipment line—including plants, land, machinery, and inventory—to the Westinghouse Air Brake Company for US$ 31 million. [ 2 ] [ 6 ] [ 7 ] In 1958, at the age of seventy, LeTourneau re-entered the earthmoving equipment manufacturing business, offering contractors a range of high capacity ...
