Trailer Brake Controller
A brake controller is usually an original equipment manufacturer or aftermarket-installed device or module. It is mounted to the tow vehicle's driver's-side dashboard area, and engages a trailer's electrical braking system either time delayed, or in proportion to the tow vehicle's brake engagement when slowing down or coming to a halt. A brake controller is not needed with a trailer surge braking system unless using modern electric over hydraulic devices. The trailer in this case usually has either electric friction brakes or electric-hydraulic trailer brake actuators. Most basic brake controllers will generally have a plus-minus gain adjustment. The tow vehicle operator sets the gain as high as possible but without the trailer brakes locking up after making a few test stops. The heavier the trailer, the higher the gain adjustment is set and therefore the less chances of wheel lock-up. A wide range of trailers contain trailer brakes (for example, larger boat trailers, horse trail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are generally ...

Original Equipment Manufacturer
An original equipment manufacturer (OEM) is generally perceived as a company that produces non-aftermarket parts and equipment that may be marketed by another manufacturer. It is a common industry term recognized and used by many professional organizations such as SAE International, ISO, and others. However, the term is also used in several other ways, which causes ambiguity. It sometimes means the maker of a system that includes other companies' subsystems, an end-product producer, an automotive part that is manufactured by the same company that produced the original part used in the automobile's assembly, or a value-added reseller.Ken Olsen: PDP-1 and PDP-8 (page 3) , economicadventure.com Automotive parts When referring to auto parts, OEM refers to the manufactur ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailer (vehicle)
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. United States In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle, high, long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight that travels over land in North America. Types ...

Overrun Brake
An overrun brake (called a surge brake when invented) is a brake system commonly used on small trailers, where the motion of the trailer with respect to the towing vehicle is used to actuate the brake. The early systems were fitted with a spring system which was not very effective. Later systems were fitted with a sliding mechanism within the coupling, which enables the drawbar to move back and forth relative to the trailer chassis. When the towing vehicle brakes, the inertia of the trailer slides the mechanism, this in turn uses the travel of this mechanism to pull on the brake rod which applies the brakes. The sliding mechanism contains a damper to even out the shock loading transmitted from the tow vehicle. Therefore, the inertia of the trailer provides the force to apply the brakes. Some systems have a ball hitch that is normally straight, but when the lead vehicle starts braking, the trailer pushes forward on the ball hitch, pitching it up which then activates a variable hyd ...

Electric Friction Brake
An electric friction brake, often referred to as just electric brake or electric trailer brake, is a brake controlled by an electric current and can be seen on medium duty trailers like caravans/RVs and consumer-grade car trailers. It is related to the electromagnetic track brake used in railways which also use electric current to directly control the brake force. Mechanical principle This describes the electrically controlled drum brake principles. The brake is built with the brake shield (1) as a base that contains the mechanism. The brake shield is mounted on an axle/spindle using the holes in the centre. The brake shoes (3) are the items performing the braking by pressing outwards at the drum that covers all the innards. The brake shoes are held in place by reactor springs (2) and an adjuster (7) spring. There are also some minor clips not pictured to keep the brake shoes in place. Braking starts with applying a current proportional to the desired brake force to the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Trailer
A horse trailer or horse van (also called a horse float in Australia and New Zealand or horsebox in the British Isles) is used to transport horses. There are many different designs, ranging in size from small units capable of holding two or three horses, able to be pulled by a pickup truck or SUV; to gooseneck designs that carry six to eight horses, usually pulled by 1-ton dually-style pickups. There are also large semi-trailers that can haul a significant number of animals. In the UK, a horsebox may also refer to a motorised vehicle adapted to carry horses (generally known as a horse van in North America or Australasia), or a railway vehicle specifically designed to carry horses. The least expensive type of trailer is the stock trailer, a trailer designed for cattle that is enclosed on the bottom, but has slits at roughly the eye level of the animals to allow ventilation. Trailers designed specifically for horses are more elaborate. Because horses are usually hauled for the pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Brake (road Vehicle)
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 apply the pressure to the brake pad or brake shoe needed to stop the vehicle. Air brakes are used in large heavy vehicles, particularly those having multiple trailers which must be linked into the brake system, such as trucks, buses, trailers, and semi-trailers, in addition to their use in railroad trains. George Westinghouse first developed air brakes for use in railway service. He patented a safer air brake on March 5, 1872. Westinghouse made numerous alterations to improve his air pressured brake invention, which led to various forms of the automatic brake. In the early 20th century, after its advantages were proven in railway use, it was adopted by manufacturers of trucks and heavy road vehicles. Design and function Air brakes are typically used on heavy trucks and buses. Typical operating pressure is approximatel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Brake
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism. History During 1904, Frederick George Heath (Heath Hydraulic Brake Co., Ltd.), Redditch, England devised and fitted a hydraulic (water/glycerine) brake system to a cycle using a handlebar lever and piston. He obtained patent GB190403651A for “Improvements in hydraulic actuated brakes for cycles and motors”, as well as subsequently for improved flexible rubber hydraulic pipes. In 1908, Ernest Walter Weight of Bristol, England devised and fitted a four-wheel hydraulic (oil) braking system to a motor car. He patented it in Great Britain (GB190800241A) in December 1908, later in Europe and the USA and then exhibited it at the 1909 London Motor Show. His brother, William Herbert Weight improved the patent (GB190921122A) and both were assigned to the Weight Patent Autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford TowCommand
The optional factory in-dash installed Ford Motor Company "TowCommand" integrated TBC (Trailer Brake Controller) system available and compatible on the heavy duty commercial Ford Super Duty line of trucks starting with the 2005 models. TowCommand has since been added to the full-size Ford F-150 pickup and the full-size Ford Expedition SUV. It is built and engineered jointly with Tekonsha who are known for their Prodigy TBC. With adjustable +/- trailer braking gain in a digital readout from 0.0 (no trailer brakes) to 10.0 (full trailer braking) in 0.5 increments and a manual override lever (to test trailer braking action), the Ford 'built into the dash' TBC provides smooth braking even when pulling up to a 15,000 lb 4-axle conventional (receiver mounted) or 26,000 lb 4-axle 5th Wheel (bed/frame mounted) trailer. TowCommand being different from most aftermarket TBCs, ties into the trucks' computer and hydraulics, so it senses truck brake pressure and can apply trailer brakes ...

Vehicle Braking Technologies
A vehicle (from la, vehiculum) is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles (motorcycles, cars, trucks, buses, mobility scooters for disabled people), railed vehicles (trains, trams), watercraft (ships, boats, underwater vehicles), amphibious vehicles (screw-propelled vehicles, hovercraft), aircraft (airplanes, helicopters, aerostats) and spacecraft.Halsey, William D. (Editorial Director): ''MacMillan Contemporary Dictionary'', page 1106. MacMillan Publishing, 1979. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833-1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions.

Automotive Accessories
The automotive aftermarket is the secondary market of the automotive industry, concerned with the manufacturing, remanufacturing, distribution, retailing, and installation of all vehicle parts, chemicals, equipment, and accessories, ''after'' the sale of the automobile by the original equipment manufacturer (OEM) to the consumer. The parts, accessories, etc. for sale may or may not be manufactured by the OEM. According to a report by the International Trade Administration in the US Department of Commerce, "''Aftermarket parts are divided into two categories: replacement parts and accessories. Replacement parts are automotive parts built or remanufactured to replace OE parts as they become worn or damaged. Accessories are parts made for comfort, convenience, performance, safety, or customization, and are designed for add-on after the original sale of the motor vehicle.''" The aftermarket encompasses parts for replacement, collision, appearance, and performance. The aftermarket provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
