Tyrrell P34B
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 var ...

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, front to back. Use This type of motor is usually used for rear-wheel drive cars, except for some Audi and SAAB models 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 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 gearbox, rotate in the opposite direction to the crankshaft. Most larger, "premium" ve ...

Bell Crank
A bellcrank is a type of crank that changes motion through an angle. The angle can be any angle from 0 to 360 degrees, but 90 degrees and 180 degrees 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, used for calling staff in large houses or commercial establishments. Angles A typical 90 degree bellcrank consists of an "L" shaped crank pivoted where the two arms of the L meet. Moving rods (or cables or ropes) are attached to the ends of the L arms. When one is pulled, the L rotates around the pivot point, pulling on the other arm. A typical 180 degree bellcrank consists of a straight bar pivoted in the center. When one arm is pulled or pushed, the bar rotates around the pivot point, pulling or pushing on the other arm. Mechanical advantage Changing the length of the arms changes the mechanical advantage of the system. Many applications do not change the direction of motion but instead amplify a ...

Contact Patch
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 the FIA's Formula One motor racing. It featured the 28th World Championship of Drivers and the 20th International Cup for Formula 1 Constructors, which 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. Jody Scheckter's Wolf won first time out, Shadow took their only victory, and Gunnar Nilsson achieved the only win of a career ended by cancer. Renault entered Grand Prix racing with a turbocharged car which was initially not very successful. The German ATS team took over the Penske cars and the South African Grand Prix was the last race a BRM ever qualified to start. Lauda departed Ferrari even before the season ended, so did not complete the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 World Championship went to McLaren driver James Hunt by one point from Ferrari's defending champion Niki Lauda, although Ferrari took the International Cup for Formula 1 Manufacturers. Hunt had moved from the Hesketh team to McLaren, taking the place of dual World Champion Emerson Fittipaldi who had moved to drive for his brother Wilson's Fittipaldi Automotive team for the season. The controversy began in Spain where Hunt was initially disqualified from first place, giving the race to Lauda, only for the decision to be overturned on appeal months later. ...

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, however, 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 by means of a fan, claimed to be for increased cooling, but which also extract ...

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".

Goodyear Tire And Rubber Company
The Goodyear Tire & Rubber Company is an American multinational tire manufacturing company founded in 1898 by Frank Seiberling and based in Akron, Ohio. Goodyear manufactures tires for automobiles, commercial trucks, light trucks, motorcycles, SUVs, race cars, airplanes, farm equipment and heavy earth-moving machinery. It also makes bicycle tires, having returned 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), Continental (Germany) and MRF (India). The company was named after American Charles Goodyear (1800–1860), inventor of 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 advertising blimp flew in 1925. Today, it is one of the most recognizable advertising icons in America. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (1965-1993) 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 companies were formed to exploit the discovery of a gas field in Saint-Marcet in the Aquitaine region of south-western France. In December 1965, RAP and BRP were merged to form Entreprise de Recherches et d'Activités Pétrolières (ERAP). ERAP had SNPA, Union Générale des Pétroles (UGP), and Union Industrielle des Pétroles (UIP) as subsidiaries. The resulting company achieved vertical integratio ...

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, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel maki ...
