Tyrrell P34
The Tyrrell P34 (Project 34), commonly known as the "six-wheeler", was a Formula One (F1) race car designed by Derek Gardner, Tyrrell's chief designer. The car used four specially manufactured 10-inch diameter (254 mm) wheels and tyres at the front, with two ordinary-sized wheels at the back. Along with the Brabham BT46B "fancar" developed in , the six-wheeled Tyrrell was one of the most radical entries ever to succeed in F1 competition and has been called the most recognisable design in the history of world motorsports. The P34 was introduced in September 1975 and began racing in the 1976 season. It proved successful and led other teams to begin design of six-wheeled platforms of their own. Changes to the design made for the 1977 season made it uncompetitive, and the concept was abandoned for Tyrrell's 1978 season. The other six-wheeled designs ended development and F1 rules later stipulated that cars must have four wheels in total. The cars later had some success in va ...

Longitudinal Engine
In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, from front to back. See also: transverse engine Use This type of motor is usually used for rear-wheel drive cars, except for some Audi, SAAB, the Oldsmobile Toronado, and the 1967 Cadillac Eldorado equipped with longitudinal engines in front wheel drive. In front-wheel drive cars a transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in the case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along the entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Crank
A bellcrank is a type of crank that changes motion through an angle. The angle can range from 0 to 360 degrees, but 90-degree and 180-degree bellcranks are most common. The name comes from its first use, changing the vertical pull on a rope to a horizontal pull on the striker of a bell to sound it. Design A typical 90-degree bellcrank consists of an L-shaped crank pivoted where the two arms of the L meet. Moving rods or cables are attached to the outer ends of the L. When one is pulled, the L rotates around the pivot point, pulling on the other rod. A typical 180-degree bellcrank consists of a straight bar that pivots at or near its center. When one rod is pulled or pushed, the bar rotates around the pivot point, pulling or pushing on the other rod. Changing the length of the bellcrank's arms changes the mechanical advantage of the system. Many applications do not change the direction of motion but instead amplify a force "in line", which a bellcrank can do in a limited space. ...

Contact Patch
The contact patch is the portion of a vehicle's tire that is in actual contact with the road surface. It is commonly used in the discussion of pneumatic (i.e. pressurized) tires, where the term is used strictly to describe the portion of the tire's tread that touches the road surface. The term “footprint” is used almost synonymously. Solid wheels also exhibit a contact patch which is generally smaller than the pneumatic “footprint”. Contact patch size The contact patch is the only connection between the road and the vehicle. Pneumatic rubber tires The size and shape of the contact patch, as well as the pressure distribution within the contact patch, are important to the ride qualities and handling characteristics of a vehicle. Since the wear characteristics of tires is a highly competitive area between tire manufacturers, a lot of the research done concerning the contact patch is considered highly proprietary and, therefore, very little is published on the subject.

1977 Formula One Season
The 1977 Formula One season was the 31st season of FIA Formula One motor racing. It featured the 28th World Championship of Drivers and the 20th International Cup for Formula 1 Constructors. The season commenced on 9 January 1977 and ended on 23 October after seventeen races, making it the longest Formula One season in the sport's history at the time. The season also included a single non-championship race for Formula One cars, the 1977 Race of Champions. Niki Lauda won his second championship, despite Mario Andretti winning more races. Lauda did not complete the season, departing Scuderia Ferrari after securing the title at the 1977 United States Grand Prix. Ferrari won its third consecutive Constructors' title, with new driver Carlos Reutemann having a solid season. The season was marred by a horrific accident during the South African GP: Tom Pryce was unable to avoid hitting 19-year-old race marshal Frederik Jansen van Vuuren, who had tried to cross the track.

1976 Formula One Season
The 1976 Formula One season was the 30th season of FIA Formula One motor racing. It featured the 1976 World Championship of Drivers and the 1976 International Cup for Formula 1 Manufacturers. The two titles were contested over a sixteen race series which commenced on 25 January and ended on 24 October. Two non-championship races were also held during the 1976 season. In an extraordinarily political and dramatic season, the Drivers' Championship went to McLaren driver James Hunt by one point from Ferrari's defending champion Niki Lauda, although Ferrari took the Manufacturers' trophy. The controversy began in Spain where Hunt was initially disqualified from first place, handing the race win to Lauda, only for the decision to be overturned on appeal months later. Ferrari did not enter the Austrian Grand Prix out of protest. Hunt won in France and, it seemed, in Britain, but the race had been restarted after a first lap pile-up and Hunt drove on an access road returning to the ...

Brabham BT46
The Brabham BT46 is a Formula One racing car designed by Gordon Murray for the Brabham team, owned by Bernie Ecclestone, for the 1978 Formula One season. The car featured several radical design elements, one of which was the use of flat panel heat exchangers on the bodywork of the car to replace conventional water and oil radiators. It was removed before the car's race debut, never to be seen again. The cars, powered by a flat-12 Alfa Romeo engine, raced competitively with modified nose-mounted radiators for most of the year, driven by Niki Lauda and John Watson, winning one race in this form and scoring sufficient points for the team to finish third in the constructors' championship. The "B" variant of the car, also known as the "fan car", was introduced at the 1978 Swedish Grand Prix as a counter to the dominant ground effect Lotus 79. The BT46B generated an immense amount of downforce utilizing a fan, claimed to be for increased cooling, but which also extracted air from ...

Derek Gardner (designer)
Derek Gardner (19 September 1931 – 7 January 2011) was a car designer known for designing advanced transmission systems. He was born in Warwick, and joined Formula One while employed by Harry Ferguson Research, developing four-wheel drive systems for Matra in 1969. He met Ken Tyrrell in 1970 and Tyrrell chose Gardner to design his chassis. The first chassis, the Tyrrell 001, was built in his garage at home and was raced in the 1970 Canadian Grand Prix. Jackie Stewart qualified the car on pole on its debut and led until an axle failed on lap 34. The car was further developed into the Tyrrell 002 and 003 and drivers Jackie Stewart and François Cevert achieved seven wins between them in . Stewart won the Drivers' World Championship and Tyrrell took the Constructors' title. Gardner's most iconic car was the Tyrrell P34, commonly known as the "six-wheeler". The car used four specially manufactured 10-inch-diameter (254 mm) wheels and tyres at the front, with two ordinar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1976 Spanish Grand Prix
The 1976 Spanish Grand Prix (formally the XXII Gran Premio de España) was a Formula One motor race held at the Circuito del Jarama in Madrid, Spain on 2 May 1976. The race was the fourth round of the 1976 Formula One season. The race was the 22nd Spanish Grand Prix and the sixth to be held at Jarama. The race was held over 75 laps of the 3.404-kilometre circuit for a total race distance of 255 kilometres. Initially the declared winner was Austrian Ferrari driver Niki Lauda driving a Ferrari 312T2 extending his Drivers' Championship lead to 23 points after first across the line James Hunt had his McLaren M23 disqualified in post-race scrutineering. Swedish driver Gunnar Nilsson took his Lotus 77 to second place with Carlos Reutemann finishing third in his Brabham BT45. McLaren appealed the disqualification and in July the appeal was upheld and Hunt re-instated as winner of the Spanish Grand Prix.

Goodyear Tire And Rubber Company
The Goodyear Tire & Rubber Company is an American multinational tire manufacturer headquartered in Akron, Ohio. Goodyear manufactures tires for passenger vehicles, aviation, commercial trucks, military and police vehicles, motorcycles, recreational vehicles, race cars, and heavy off-road machinery. It also licenses the Goodyear brand to bicycle tire manufacturers, returning from a break in production between 1976 and 2015. As of 2017, Goodyear is one of the top five tire manufacturers along with Bridgestone (Japan), Michelin (France), Pirelli (Italian) and Continental AG, Continental (Germany). Founded in 1898 by Frank Seiberling, the company was named after American Charles Goodyear (1800–1860), inventor of Vulcanization, vulcanized rubber. The first Goodyear tires became popular because they were easily detachable and required little maintenance. Though Goodyear had been manufacturing airships and balloons since the early 1900s, the first Goodyear Blimp, Goodyear advertising ...

Elf Aquitaine
Elf Aquitaine is a French brand of oils and other motor products (such as brake fluids) for automobiles and trucks. Elf is a former petroleum company which merged with TotalFina to form "TotalFinaElf". The new company changed its name to Total in 2003 and TotalEnergies in 2021. Elf has been as a major brand of TotalEnergies since then. History Founding and mergers (1965–1979) Elf Aquitaine's heritage is rooted among three French oil companies: ''Régie Autonome des Pétroles (RAP),'' ''Société Nationale des Pétroles d'Aquitaine (SNPA),'' and ''Bureau de Recherches de Pétroles (BRP''). These entities were formed to exploit a gas field discovered in Saint-Marcet in the Aquitaine region of south-western France in 1939. In the early 1960s, with a view to create a French national champion with oil and gas considered as a strategic resource for economic development, under President de Gaulle's leadership, further state-owned companies were set up with specific objectiv ...

Differential (mechanics)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and Analog computer, analogue computers. Differentials can also provide a gear ratio between the input and output shafts (called the "axle ratio" or "diff ratio"). For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear. History Milestones in the design or use of differentials include: * 100 BCE–70 BCE: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by Sponge diving, sponge divers, and modern research suggests that it used a differential gear to determine the angle between the ecliptic positions of the Sun and Moon, and th ...
