Lotus 18
The Lotus 18 was a race car designed by Colin Chapman for use by Lotus in Formula One, Formula Two, and Formula Junior, which was used from 1960 until 1966 in F1. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One
Formula One (F1) is the highest class of worldwide racing for open-wheel single-seater formula Auto racing, racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of motorsport since its 1950 Formula One season, inaugural running in 1950 and is often considered to be the pinnacle of motorsport. The word ''Formula racing, formula'' in the name refers to Formula One regulations, the set of rules all participant cars must follow. A Formula One season consists of a series of races, known as List of Formula One Grands Prix, Grands Prix. Grands Prix take place in multiple countries and continents on either purpose-built List of Formula One circuits, circuits or closed roads. A List of Formula One World Championship points scoring systems, points scoring system is used at Grands Prix to determine two annual World Championships: List of Formula One World Drivers' Champions, one ...

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. Chief applications include buildings and vehicles. 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 commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lotus 20
The Lotus 20 is a Formula Junior car built by Lotus for the 1961 season as a successor to the Lotus 18. The chassis is a spaceframe, clothed in fibreglass bodywork. It has 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 has 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. Lotus 20B The 20B was mostly the same as the 20, but with sway bar and ...

Lotus 12
The Lotus 12 was a British racing car used in Formula Two and Formula One. It debuted at the 1958 Monaco Grand Prix and was Colin Chapman's first single-seat racer. Design Colin Chapman's first foray into single-seater racing, the 12 appeared in 1958. 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 "C ...

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 co ...

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: he invented the first practical pneumatic tyres for his child's tricycle. 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 Stephen Street, 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 tyres s ...

Sequential Gearbox
A sequential manual transmission, also known as a sequential gearbox or sequential transmission, is a type of non-synchronous manual transmission used mostly in 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 manu ...

Harry Mundy
Harry Mundy (1915–1988) was a British car engine designer and motoring magazine editor. Education and career 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 F ...

RMR Layout
In automotive design, an RMR, or rear mid-engine, rear-wheel-drive layout is one in which the rear wheels are driven by an engine placed with its center of gravity in front of the rear axle, and thus right behind the passenger compartment. Nowadays more frequently called 'RMR', to acknowledge that certain sporty or performance focused front-engined cars are also "mid-engined", by having the main engine mass behind the front axle, RMR layout cars were previously (until ca. the 1990) just called MR, or mid-engine, rear-wheel-drive layout), because the nuance between distinctly front-engined vs. front ''mid-engined'' cars often remained undiscussed. In contrast to the fully rear-engine, rear-wheel-drive layout, the center of mass of the engine is in front of the rear axle. This layout is typically chosen for its favorable weight distribution. Placing the car's heaviest component within the wheelbase minimizes its rotational inertia around the vertical axis, facilitating turn-in or ...
