Twist-grip
A twistgrip is a handle that can be twisted to operate a control. It is commonly found as a motorcycle's right Motorcycle handlebar, handlebar grip to control the throttle, but is sometimes found elsewhere, such as on a bicycle as a gearshift, and in helicopters. History The first use of the twist grip throttle control was on the Roper steam velocipede of 1867-69. Rather than a sleeve that rotated around the handlebar, Sylvester H. Roper's Steam engine, steam motorcycle's entire handlebar rotated, with a dual mode operation. When rotated forward it opened the throttle, and when rotated backwards it applied the spoon brake. ''Motorcycle Consumer News'' design columnist Glynn Kerr said that pioneering this technology was a point in favor of the Roper's precedence as the first motorcycle, in response to ''Cycle World'' Technical Editor Kevin Cameron (journalist), Kevin Cameron's position that the 1885 Daimler Reitwagen, Daimler ''Reitwagen'' was more deserving because it used the m ...

Production Vehicle
Production vehicles or production cars are mass-produced models of automobiles offered for sale to the public and can be legally driven on public roads. Legislation and other industrial rules define the production vehicle within particular countries or uses. There is no single fixed global definition of the term. Origin The earliest use of the term ''production car'' being applied to motor cars, found to date, was in a June 1914 American advertisement for a Regal motor car. The phrase was a shortened form of ''mass-produced'' or ''quantity-produced'' car. The phrase was also used in terms of the car to be made in production, as opposed to the prototype. At that time, production cars referred to less expensive vehicles, such as the Ford Model T, made in relatively large numbers on production lines instead of the more exclusive coach-built models. Now, the term has broadened to include hand-assembled vehicles and those made on production or assembly line. The main criterion ...

Gottlieb Daimler
Gottlieb Wilhelm Daimler (; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine. Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream. In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Reitwagen, Petroleum Reitwagen (Riding Car) and, in the next year, to a Coach (carriage), coach, and a boat. Daimler call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Year
The model year (sometimes abbreviated as MY) is a method of describing the version of a product which has been produced over multiple years. The model year may or may not be the same as the calendar year in which the product was manufactured. Automobiles United States and Canada Automobiles in the United States and Canada are identified and regulated by model year, whereas other markets use production date (month/year) to identify specific vehicles, and model codes in place of the "year" (model year) in the North American make-model-year identifier. In technical documents generated within the auto industry and its regulating agencies such as the U.S. National Highway Traffic Safety Administration and United States Environmental Protection Agency and Transport Canada and Environment Canada, the letters ''MY'' often precede the year (as in ''MY2019'' or ''MY93''). Even without this prefix, however, in the North American context it is usually the model year rather than the ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle Land-speed Record
The motorcycle land-speed record is the fastest speed achieved by a motorcycle on land. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions. AMA National Land Speed Records requires two passes the same calendar day in opposite directions over a timed mile/kilometre while FIM Land Speed World Records require two passes in opposite directions to be over a timed mile/kilometre completed within two hours. These are special or modified motorcycles, distinct from the fastest production motorcycles. The first official FIM record was set in 1920, when Gene Walker rode an Indian on Daytona Beach at . Since late 2010, the Ack Attack team has held the motorcycle land speed record at . History The first generally recognized motorcycle speed records were set unofficially by Glenn Curtiss, using aircraft engines of his own manufacture, first in 1903, when he achieved at Yonkers, New York using a V-twin, and then on January 24, 190 ...

Glenn Curtiss
Glenn Hammond Curtiss (May 21, 1878 – July 23, 1930) was an American aviation and motorcycling pioneer, and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908, Curtiss joined the Aerial Experiment Association, a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia, to build flying machines. Curtiss won a race at the world's first international air meet in France and made the first long-distance flight in the U.S. His contributions in designing and building aircraft led to the formation of the Curtiss Aeroplane and Motor Company, which later merged into the Curtiss-Wright Corporation. His company built aircraft for the U.S. Army and Navy, and, during the years leading up to World War I, his experiments with seaplanes led to advances in naval aviation. Curtiss civil and military aircraft were some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch
A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission. By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels. Another example of clutch usage is in electric drills. The clutch's input shaft is driven by a motor and the output shaft is connected to the drill bit (via several intermediate components). The clutch allows the drill bit to either spin at the same speed as the motor (clutch engaged), spin at a lower speed than the motor (clutch slipping) or remain stationary while the motor is spinning (clutch disengaged). Types Dry clutch A ''dry clutch'' uses dry friction to transfer power from the input shaft to the output shaft, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idler-wheel
{{refimprove, date=June 2015 An idler-wheel is a wheel which serves only to transmit rotation from one shaft to another, in applications where it is undesirable to connect them directly. For example, connecting a motor to the platter of a phonograph, or the crankshaft-to-camshaft gear train of an automobile. Because it does no work itself, it is called an " idler". Friction drive An idler-wheel may be used as part of a friction drive mechanism. For example, to connect a metal motor shaft to a metal platter without gear noise, early phonographs used a rubber idler wheel. Likewise, the pinch roller in a magnetic tape transport is a type of idler wheel, which presses against the driven capstan to increase friction. Idler pulley In a belt drive system, idlers are often used to alter the path of the belt, where a direct path would be impractical. Idler pulleys are also often used to press against the ''back'' of a pulley in order to increase the wrap angle (and thus contact ar ...

Belt (mechanical)
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). The belt drive can also be used to change the speed of rotation, either up or down, by using different sized pulleys. As a source of motion, a conveyor belt is one application where the belt is adapted to carry a load continuously between two points. History The mechanical belt drive, using a pulley machine, was first mentioned in the text of the ''Dictionary of Local Expressions'' by the Han ...
