  2. Combined braking system - Wikipedia

    en.wikipedia.org/wiki/Combined_braking_system

    A combined braking system (CBS), also called linked braking system (LBS), is a system for linking front and rear brakes on a motorcycle or scooter. [1] In this system, the rider's action of depressing one of the brake levers applies both front and rear brakes. The amount of each brake applied may be determined by a proportional control valve.

  3. Landing gear - Wikipedia

    en.wikipedia.org/wiki/Landing_gear

    The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.

  4. S-cam - Wikipedia

    en.wikipedia.org/wiki/S-cam

    An S-cam is part of a braking system used in heavy vehicles such as trucks and wheeled machinery. It consists of a shaft, usually around 4 to 25 inches long, turned at one end by means of an air-powered brake booster and lever with an S-shaped cam at the wheel end. Turning the shaft pushes the brake shoes against the drum, producing friction.

  5. Caster - Wikipedia

    en.wikipedia.org/wiki/Caster

    A swivel caster. A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment. High capacity, heavy duty ...

  6. Air caster - Wikipedia

    en.wikipedia.org/wiki/Air_caster

    An air caster is a pneumatic lifting device used to move heavy loads on flat, non- porous surfaces. Its operation is similar to a hovercraft, as it uses a thin layer of air as a way to float a very small distance off the ground. Compressed air enters an airbag shaped like a torus, [1] and when the bag is filled it creates an airtight seal with ...

  7. 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 ...

  8. Steam locomotive components - Wikipedia

    en.wikipedia.org/wiki/Steam_locomotive_components

    Powered by steam, it compresses air for operating the train air brake system. [3]: 2 The Westinghouse air brake system is used world-wide; [3]: 93 in Europe two systems that use the same principle are the Kunze-Knorr and Oerlikon systems. It can be a single-stage or, when larger capacity is needed, a two-stage cross-compound compressor.

  9. Retarder (mechanical engineering) - Wikipedia

    en.wikipedia.org/wiki/Retarder_(mechanical...

    Retarder (mechanical engineering) Torque converter, opened, interior similar to a retarder. A retarder is a device used to augment or replace some of the functions of primary friction -based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the ...
