Lotus 18
The Lotus 18 was a race car designed by Colin Chapman for use by Lotus in Formula Junior, Formula Two, and Formula One. Overview Lotus 18 was the first mid-engined car built by Lotus and was a marked improvement over Chapman's early and only moderately successful front-engined formula cars, the 12 and 16. It was introduced for the 1960 F1, F2 and FJ seasons, with about 27 examples of the F1 and F2 versions and 110 of the FJ versions. As a stop-gap before the introduction of the 18's successor models, the Lotus 20 for F2/FJ and 21 for F1, some 18 chassis were rebodied with 21 skins to create the interim Lotus 18/21 hybrid derivative. The 18 was replaced by the Lotus 21 in Formula One and the Lotus 20 in Formula Junior in 1961. Design The car was a classic Chapman design, being extremely light and simple; the body was made up of lightweight panels bolted to heavily-triangulated tube frame (spaceframe) chassis. Thus the car was rigid, strong and light, maintaining the 16's fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issued ...

Spaceframe
In architecture and structural engineering, a space frame or space structure ( 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral truss being one of his inventions. Max Mengeringhausen developed the space grid system called MERO (acronym of ''MEngeringhausen ROhrbauweise'') in 1943 in Germany, thus initiating the use of space trusses in architecture. The commonly used method, still in use has individual tubular m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lotus 20
Lotus 20 was a Formula Junior car built by Lotus for the 1961 season as a successor to the Lotus 18. The chassis was a spaceframe, clothed in fibreglass bodywork. It had front double wishbone suspension, but the rear had a lower wishbone with the driveshaft being fixed length and therefore used as a top link. Originally fitted with Alfin drum brakes at all four corners, it was soon upgraded to discs in front and inboard drums at the rear. Equipped as standard with the Cosworth Mk.IV engine and with either a Renault Dauphine gearbox or Hewland-modified VW box. Compared with the Lotus 18, the 20 had a much reduced frontal area and lower centre of gravity, aided by the fact the driving position was reclined so the driver was nearly lying down, compared with being more upright in the Lotus 18. A 1962 Lotus 20 can be found hanging from the ceiling on the first floor at the Canadian Automotive Museum, located in Oshawa, Ontario, Canada. Lotus 20B The 20B was mostly the same ...

Lotus 12
The Lotus 12 was a Formula Two and Formula One racing car. Design Colin Chapman's first foray into single-seater racing, the 12 appeared in 1957. It featured a number of important innovations Chapman would use on later models. To better use the power of the Coventry Climax engine, it was designed, as usual, for low weight and low drag, relying on a space frame. It placed the driver as low as possible, reducing the height of transmission tunnel by way of a "conceptually brilliant" five-speed sequential-shift transaxle located in the back. This transaxle was designed by Richard Ansdale and Harry Mundy. The gearbox had a (long-undiagnosed) oil starvation problem, thus earned the nickname "Queerbox" for its unreliability. Although the first two examples of Lotus 12 had De Dion rear suspension, it also introduced a new suspension configuration with what came to be called "Chapman struts" in the rear, essentially a MacPherson strut with a fixed length halfshaft with universal joints ...

Mid-engine
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive compon ...

Race Car
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1960 Argentine Grand Prix
The 1960 Argentine Grand Prix was a Formula One motor race held at Buenos Aires on 7 February 1960. It was race 1 of 10 in the 1960 World Championship of Drivers and race 1 of 9 in the 1960 International Cup for Formula One Manufacturers. This was the last Argentine Grand Prix until 1972, and the last to be held on the No. 4 configuration of the circuit. The race was won by Bruce McLaren, his second consecutive victory, having won his first at Sebring at the end of the 1959 season. Stirling Moss suffered a suspension failure while leading, and took over Maurice Trintignant's Cooper, but was not awarded points for third place as a result of the shared drive, a rule that had been in place since 1958. Venezuelan driver Ettore Chimeri participated in his only grand prix. He was killed two weeks later driving a Ferrari 250 TR in Havana. He was the first driver from his country in Formula One, and the last until Johnny Cecotto in 1983. It was the only grand prix appearances for ...

Dunlop Rubber
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable Radial tire, radial tyres swept through the market. After taking on excessive debt Dunlop w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequential Gearbox
A sequential manual transmission, also known as a sequential gearbox, or a sequential transmission, is a type of non-synchronous manual transmission used mostly for motorcycles and racing cars. It produces faster shift times than traditional synchronized manual transmissions, and restricts the driver to selecting either the next or previous gear, in a successive order. Design A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. On a sequential ...

Harry Mundy
Harry Mundy (1915–1988) was a British car engine designer and motoring magazine editor. He was educated at King Henry VIII School in Coventry and went on to serve his apprenticeship with Alvis. He left them in 1936 to join English Racing Automobiles (ERA) in Bourne, Lincolnshire as a draughtsman. Also at ERA was Walter Hassan who became a lifelong friend; the two would work together later at Jaguar on engine development. He left ERA in 1939 and returned to Coventry to work at the Morris Engines factory. After World War II he moved to British Racing Motors (BRM) in 1946 as head of the design office, being involved in the design of the BRM V16 Formula One engine, before moving on again in 1950 to Coventry Climax engines as chief designer working on the FWA engine. His career then took a change in direction and he moved into journalism becoming Technical Editor of '' The Autocar'' magazine in 1955 but while there he also worked on the design of the Ford based twin-cam engine ...
