Endurance Racing (motorsport)
Endurance racing is a form of motorsport racing which is meant to test the durability of equipment and endurance of participants. Teams of multiple drivers attempt to cover a large distance in a single event, with participants given a break with the ability to change during the race. Endurance races can be run either to cover a set distance in laps as quickly as possible, or to cover as much distance as possible over a preset amount of time. One of the more common lengths of endurance races has been running for , or roughly six hours. Longer races can run for , 12 hours, or even 24 hours. Teams can consist of anywhere from two to four drivers per event, which is dependent on the driver's endurance abilities, length of the race, or even the rules for each event. Origins Coppa Florio was an Italian car race started in 1900, and renamed in 1905 when Vincenzo Florio offered the initial 50 000 Lira and a cup designed by Polak of Paris. The Brescia race visited the route Brescia-Cremon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eifelrennen
The Eifelrennen was an annual motor race, organised by ADAC Automobile Club from 1922 to 2003, held in Germany's Eifel mountain region even before the Nürburgring was built there. History Starting from 1922, the first races were held on a 33 km long combination of public roads around Nideggen, Wollersheim, Vlatten, Heimbach, Hasenfeld and other villages in the Eifel mountains, similar to the Targa Florio which was a very important race at that time, and popular in Germany due to two wins by Mercedes (still without Benz then). In 1922, all vehicles were allowed, cars, motorbikes, and even bicycles with supporting engines. Over 100 entrants showed up to compete in the 10-lap event. The track was not paved, and muddy after heavy rains. From 1924 to 1926, the races for 2 and 4 wheels were held on separate days, and classes were introduced. Still, several fatal accidents happened. Even spectator stands collapsed, caused by stormy weather. The unsatisfying safety situat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Swing Axle
A swing axle is a simple type of independent (rear wheel) suspension designed and patented by Edmund Rumpler in 1903. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow uneven road surfaces independently, thus enabling the vehicle's wheels to maintain better road contact and holding; plus each wheel's reduced unsprung weight means their movements have less impact on the vehicle as a whole. The first automotive application was the Rumpler Tropfenwagen, later followed by the Mercedes 130H/150H/170H, the Standard Superior, the Volkswagen Beetle and its derivatives, the Chevrolet Corvair, and the roll-over prone M151 jeep amongst others. Some later automobile rear swing axles have universal joints connecting the driveshafts to the differential, which is attached to the chassis. Swing axles do not have universal joints at the wheels — the wheels are always perpendicular to the driveshafts; the design is therefore not suitable ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

Mercedes-Benz W188
The Mercedes-Benz W188 was a two-door luxury sports tourer produced by Mercedes-Benz between 1951 and 1958. The company's most expensive and exclusive automobiles, the elegant, hand-built 300 S (1951-1954) and its successor 300 Sc (1955-1958) were the pinnacle of the Mercedes line of their era. The pair's conservative styling belied their technological advances, sharing numerous design innovations and mechanical components with the iconic Mercedes-Benz 300 SL "Gullwing", including engine, suspension, and chassis. 300 S The hand-built two-door 300 S (W188) was Mercedes-Benz's top-end vehicle on its introduction at the Paris Salon in October 1951. It was available as a 2-seat roadster, 2+2 coupé, and cabriolet (with landau bars, officially ''Cabriolet A''). Although mechanically similar to the much larger contemporary four-door 300 (W186), the additional craftsmanship, visual elegance, and 50% higher price tag elevated the W188 to the apex of its era's luxury cars. The 300 S w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solex Carburetor
Solex is a French manufacturer of carburetors and the powered bicycle VéloSoleX. Solex carburetors were used by many European automobile companies and were licensed to Japanese maker Mikuni. History The Solex company was founded by Marcel Mennesson and Maurice Goudard to manufacture vehicle radiators. These were fitted to several makes of early cars including Delaunay-Belleville and buses of the Paris General Omnibus company. After World War I, the radiator business went into decline and the company bought the rights to the carburetor patents of Jouffret and Renée and named them Solex after their business. The Solex brand is now owned by Magneti Marelli. The original Solex company changed its name in 1994 to Magneti Marelli France and on May 31, 2001, Magneti Marelli France partially bought its assets (including the trademark SOLEX) from Magneti Marelli Motopropulsion France S.A.S. Carburetors Solex carburetors were widely used by many European makers and under license to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercedes-Benz W186
The Mercedes-Benz W186 Model 300 was a four-door luxury sedan produced by Mercedes-Benz between 1951 and 1957. It was the company's flagship model at the time, succeeding the World War II era W150. Three versions were produced in succession, known informally as the 300a (or simply 300), 300b, and 300c. An enlarged "300d" variant built on the W189 chassis succeeded it in late 1957. Also referred to as a "Type 300", the W186 was equal in features and price but superior in performance to the rival Rolls-Royce Silver CloudClassic and Sportscar Magazine, February 1994, Pp. 52-55 and Bentley S1. Favored by statesmen and business leaders, it offered options such as a glass partition, VHF mobile telephone, and dictation machine. The W186 is often identified as an Adenauer after Konrad Adenauer, the first Chancellor of the Federal Republic of Germany (West Germany), who employed six custom cabriolet, hardtop saloon, and landaulet versions of the W186 and its successor W189 during his ...

Inline 6
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 ...

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] |
Mercedes-Benz 300 SL
The Mercedes-Benz 300 SL (chassis code W 198) is a two-seat sports car which was produced by Mercedes-Benz as a gullwinged coupe (1954–1957) and roadster (1957–1963).Werner Oswald: ''Mercedes-Benz Personenwagen 1945–1985''. Motorbuch Verlag, Stuttgart 2007, , S. 46 u. 70. It was based on the company's 1952 racer, the W194, with mechanical direct fuel injection which boosted power almost 50 percent in its three-liter overhead camshaft straight-six engine. Capable of reaching a top speed of up to , it was a sports car racing champion and the fastest production car of its time. Max Hoffman, Mercedes-Benz's United States importer at the time, inspired the 300 SL and saw an American market for such a car. The company introduced the 300 SL in February 1954 at the International Motor Sports Show in New York City (instead of Europe) to get it into US buyers' hands sooner.

Mercedes-Benz 300 SLR
The Mercedes-Benz 300 SLR (W 196 S) was a 2-seat sports racing car that took part in the 1955 World Sportscar Championship before a catastrophic crash and fire at Le Mans later that year ended its domination prematurely. The car was designated "SL-R" (for ''Sport Leicht-Rennen'', eng: ''Sport Light-Racing''), which was later condensed to "SLR". Technically, the W 196 S is based on the W 196 R, but has a slightly different engine, displacing 3 litres. Just as the W 196 R Formula One racer's M 196 R engine, the W 196 S's M 196 S engine is a direct-injected 3-litre straight 8 engine (but with a 78 mm bore and stroke); its rated power is . The W 196 S's '' monoposto'' driving position was modified to standard two-abreast seating, headlights were added, and a few other changes made to adapt a strictly track competitor to a 24-hour road/track sports racer.
