[2] In 2007, the Vehicle Control Systems was spun off as WABCO Holdings Inc., an American provider of electronic braking, stability, suspension and transmission automation systems for heavy-duty commercial vehicles.

  3. Railway air brake - Wikipedia

    en.wikipedia.org/wiki/Railway_air_brake

    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. The mechanical linkage can become quite elaborate, as it evenly distributes force ...

    Wabtec facility, Greensburg, Pennsylvania. Westinghouse Air Brake Technologies Corporation, commonly known as Wabtec, is an American company formed by the merger of the Westinghouse Air Brake Company (WABCO) and MotivePower Industries Corporation in 1999.

  6. 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.

  7. Governor (device) - Wikipedia

    en.wikipedia.org/wiki/Governor_(device)

    A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...

  8. Centrifugal governor - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_governor

    The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid (steam) supplying the prime mover. As the speed of the prime mover increases, the central spindle of ...

  9. Variable-pitch propeller (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Variable-pitch_propeller...

    This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch. Most engines produce their maximum power in a narrow speed band. The CSU allows the engine to operate in its most economical range of rotational speeds , regardless of whether the aircraft is taking off or cruising.
