Queerbox
The Queerbox was the nickname for an early Sequential manual transmission, sequential manual transaxle used by Team Lotus, Lotus racing cars of the late-1950s and early-1960s, and was very similar in design and operation to a Motorcycle transmission, motorcycle gearbox. It was infamously unreliable. Lotus Twelve origins The Lotus Twelve was the first to use the infamous Lotus ''Queerbox'' transaxle. This was developed to be, in typical Colin Chapman fashion, the smallest and lightest five-speed transmission possible, also to have a low driveshaft line allowing a low driving position, thus lower centre of mass and air resistance. Chapman also chose a transaxle over the usual gearbox and rear axle layout, as had been used in the first Twelve, as this gave a lower polar moment of inertia. The initial design, the work of Chapman and Harry Mundy, began with the principle of the most compact layout, with the gear cluster arranged in a closely spaced stack, akin to a motorcycle transmi ...

Sequential Manual Transmission
A sequential manual transmission, also known as a sequential gearbox or sequential transmission, is a type of Non-synchronous transmission, non-synchronous manual transmission used mostly in motorcycles and Auto racing, racing cars. It produces faster shift times than traditional Manual transmission#Synchronized transmission, 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 non-synchronous transmission, 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 (ra ...

Pawl
A pawl is a movable lever that engages a fixed component to either prevent movement in one direction or restrain it altogether. As such, it is a type of latch and can also be considered a type of dog. It typically consists of a spring-loaded lever that engages a mating component at a steep enough angle to restrain it. Pawls are often tapered, being widened at their pivot for anchoring and narrow at their tip. Applications ;Anchor windlass: A pawl is used in an anchor windlass to prevent a free-spooling chain by grabbing and snubbing an individual link. Similar mechanisms include a Devil's claw, or a claw and dog. ;Ratchet: A pawl is used in combination with a ratchet gear in socket wrenches, bicycle freehubs, winches, ratchet reels for diving, fishing, and many other applications. ;Ladder: Dogs (in the form of pawls) are used on extension ladders to temporarily anchor their sections to one-another. ;Table saw: Pawls are used on table saws to prevent a workpiece being ...

Automobile Transmissions
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keith Duckworth
David Keith Duckworth (10 August 1933 – 18 December 2005) was an English mechanical engineer. He is most famous for designing the Cosworth DFV (Double Four Valve) engine, an engine that revolutionised the sport of Formula One. Early life and education Duckworth was born in Blackburn, Lancashire, and was educated at Giggleswick School. Duckworth served his two years of national service with the Royal Air Force, during which time he briefly trained to become a pilot but was grounded for dangerous and incompetent flying and was reclassified as a navigator. Duckworth claimed that allergy to medication he was receiving caused his flying problem - in civilian life he became a keen light aircraft and helicopter pilot. After completing his tour of duty, which he finished as a navigator, Duckworth studied engineering at Imperial College London, earning a BSc degree in 1955. Early career After university he began working for Lotus as a gearbox engineer. Given the task of fix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoid
A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth. A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs. Handedness A right hand spiral bevel gear is one in which the outer half of a tooth is inclined in the clockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. A left hand spiral bevel gear is one in which the outer half of a tooth is inclined in the counterclockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. ...

1958 Monaco Grand Prix
The 1958 Monaco Grand Prix was a Formula One motor race held on 18 May 1958 at Circuit de Monaco, Monaco. It was race 2 of 11 in the 1958 World Championship of Drivers and race 2 of 10 in the 1958 International Cup for Formula One Manufacturers. The race was the 16th Monaco Grand Prix and was held over 100 laps of the three kilometre circuit for a total race distance of 314 kilometres. The race was won by French driver Maurice Trintignant in the second and final Grand Prix victory of his long career. The win was the second consecutive victory for the privateer Rob Walker Racing Team. Trintignant took the teams newly acquired Cooper T45 to a twenty-second victory over Italian driver Luigi Musso driving a Ferrari 246 F1 with Musso's British teammate Peter Collins (racing driver), Peter Collins (Ferrari 246 F1) was third. Trintignant's win put the superiority of front-engined cars in doubt. Musso's second place put him into a four-point championship lead over Moss and Trintignant. ...

Spline (mechanical)
A spline is a ridge or tooth on a drive shaft that matches with a groove in a mating piece and transfers torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear. Adjacent images in the section below show a transmission input shaft with male splines and a clutch plate with mating female splines in the center hub, where the smooth tip of the axle would be supported in a pilot bearing in the flywheel (not pictured). An alternative to splines is a keyway and key, though splines provide a longer fatigue life, and can carry significantly greater torques for the size. Types There are several types of splines: ;Parallel key spline: where the sides of the equally spaced grooves are parallel in both directions, radial and axial. ;Involute spline: where the sides of the equally spaced grooves are involute, as with an involute gear, but not as tall.

Archie Butterworth
Archibald James Butterworth (19 June 1912 – 12 February 2005) was an inventor and racing motorist who, in 1948, designed and constructed the ''A.J.B. Special'', a four-wheel drive Formula One car. He was winner of the Brighton Speed Trials in 1949 and 1951. After a serious accident in 1951, he gave up competition, but continued to supply race car engines of his own design, notably to Bill Aston for the Aston Butterworth Grand Prix motor racing, Grand Prix car and Archie Scott Brown for the Elva (car manufacturer), Elva-Butterworth sports racing car. Early life Educated at the Mount St Mary's College, attended University College, London, but left to join the army: Irish Guards, then RASC-MT as driving instructor. Posted to special unit in Egypt.
