Triumph Sprung Hub
The Triumph sprung hub is a motorcycle suspension unit contained within a rear wheel hub. It was designed by Triumph engineer Edward Turner to give Triumph's existing rigid frames the option of rear suspension. It was one of the first motorcycle components to have a safety warning cast into its housing. Design and development Edward Turner designed Triumph's sprung hub in 1938. The design was inspired by Dowty hubs with suspension within them, as used in the fixed landing gear of Gloster Gladiator fighter aircraft. Turner's design used a plunger-type suspension made small enough to fit inside the wheel hub. With one spring above the rear axle and two below, the sprung hub provided about two inches of vertical travel and weighed more than a conventional hub. It was designed to allow rear suspension to be offered optionally without altering Triumph's existing frames. The sprung hub did not provide a drive gear for the speedometer, so the design of the transmission was revised to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suspension (motorcycle)
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations. The typical motorcycle has a pair of fork tubes for the front suspension, and a swingarm with one or two shock absorbers for the rear suspension. Front suspension The most common form of front suspension for a modern motorcycle is the telescopic fork. Other fork designs are girder forks, suspended on sprung parallel links (not common since the 1940s) and bottom leading link designs, not common since the 1960s. Some manufacturers (e.g. Greeves) used a version of the swinging arm for front suspension on their motocross designs. A single-sided version of the idea is also used in motor scooters such as the Vespa. The hub-center steering as developed by Ascanio Rodorigo, on a concept associated to Massimo Tamburini is a complex front swingarm alternat ...

Triumph Engineering
Triumph Engineering Co Ltd was a British motorcycle manufacturing company, based originally in Coventry and then in Meriden. A new company, Triumph Motorcycles Ltd, based in Hinckley, gained the name rights after the end of the company in the 1980s and is now one of the world's major motorcycle manufacturers. Origins The company was started by Siegfried Bettmann, who had emigrated from Nuremberg, part of the German Empire, to Coventry in England in 1883. In 1884, aged 20, Bettmann had founded his own company, the S. Bettmann & Co. Import Export Agency, in London. Bettmann's original products were bicycles, which the company bought and then sold under its own name. Bettmann also distributed sewing machines imported from Germany. In 1886, Bettmann sought a more specific name, and the company became known as the Triumph Cycle Company. A year later, the company was registered as the New Triumph Co. Ltd, now with funding from the Dunlop Pneumatic Tyre Company. During that year, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Turner (motorcycle Designer)
Edward Turner (24 January 1901 – 15 August 1973) was an English motorcycle designer. He was born in Camberwell in the London Borough of Southwark, on the day King Edward VII was proclaimed King. In 1915, Turner had his first ride on a motorcycle, a Light Tourist New Imperial. Turner Special On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, , with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear. Turner built his first bike in 1927, using his second design, a 350 cc OHC single. ''The Motor Cycle'' published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Specia ...

Dowty Group
Dowty Group was a leading British manufacturer of aircraft equipment. It was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index. The firm ceased operating as an individual entity following its acquisition by TI Group in 1992. The company has its origins as the ''Aircraft Components Company'' in 1931 and the work of British inventor and businessman George Dowty. In 1934, Dowty achieved its breakthrough sale of its innovative undercarriage designs, being contracted by the Gloster Aircraft Company to provide oleo struts for the Gloster Gauntlet biplane. In 1935, as the business expanded to meet demand, Dowty founded a new manufacturing venture to produce his aviation products, which was named ''Dowty Aviation''. It would quickly secure numerous additional orders and manufacturing facilities to cope with the pressing demands of the Second World War, a significant majority of British aircraft production incorporating the firm's various products. ...

Gloster Gladiator
The Gloster Gladiator is a British biplane fighter. It was used by the Royal Air Force (RAF) and the Fleet Air Arm (FAA) (as the Sea Gladiator variant) and was exported to a number of other air forces during the late 1930s. Developed privately as the Gloster SS.37, it was the RAF's last biplane fighter aircraft, and was rendered obsolete by newer monoplane designs even as it was being introduced. Though often pitted against more formidable foes during the early days of the Second World War, it acquitted itself reasonably well in combat. The Gladiator saw action in almost all theatres during the Second World War, with a large number of air forces, some of them on the Axis side. The RAF used it in France, Norway, Greece, the defence of Malta, the Middle East, and the brief Anglo-Iraqi War (during which the Royal Iraqi Air Force was similarly equipped). Other countries deploying the Gladiator included China against Japan, beginning in 1938; Finland (along with Swedish voluntee ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-twin Engine
A straight-twin engine, also known as an inline-twin, vertical-twin, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, Jet Skis, all-terrain vehicles, tractors and ultralight aircraft. Various different crankshaft configurations have been used for straight-twin engines, with the most common being 360 degrees, 180 degrees and 270 degrees. Terminology The straight-twin layout is also referred to as "parallel-twin", "vertical-twin" and "inline-twin". Some of these terms originally had specific meanings relating to the crankshaft angle or engine orientation, however they are often also used interchangeably. In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees, since the two pistons are in the same direction (i.e. parallel to each o ...
