Torsen
Torsen Torque-Sensing (full name Torsen traction) is a type of limited-slip differential used in automobiles. It was invented by American Vernon Gleasman and manufactured by the Gleason Corporation. Torsen is a portmanteau of Torque-Sensing. ''TORSEN'' and ''TORSEN Traction'' are registered trademarks of JTEKT Torsen North America Inc (formerly Zexel Corporation, formerly Gleason Power Systems). All Torsen differentials have their origin in the Dual-Drive Differential that was invented and patented by Gleasman in 1958. Use Torsen differentials can be used in one or more positions on a motor vehicle: * center—used to apportion torque appropriately between front and rear axles on an all-wheel drive vehicle. * rear—used to apportion torque appropriately between left and right sides in rear axles. This may be on either a rear-wheel drive or a four-wheel drive vehicle. * front—used to apportion torque appropriately between left and right sides in front axles. This may be on ei ...

Quattro (four-wheel-drive System)
quattro (meaning ''four'' in Italian) is the trademark used by the automotive brand Audi to indicate that all-wheel drive (AWD) technologies or systems are used on specific models of its automobiles.Audi.com - Glossarquattro The word "quattro" is a registered trademark of Audi AG, a subsidiary of the German automotive concern, Volkswagen Group. Quattro was first introduced in 1980 on the permanent four-wheel drive Audi Quattro model, often referred to as the '' Ur-Quattro'' (meaning "original" or "first"). The term quattro has since been applied to all subsequent Audi AWD models. Due to the nomenclature rights derived from the trademark, the word quattro is now always spelled with a lower case "q", in honour of its former namesake. Other companies in the Volkswagen Group have used different trademarks for their 4WD vehicles. While Audi has always used the term "quattro", Volkswagen-branded cars initially used ''" syncro"'', but more recently, VW uses ''" 4motion"''. Ško ...

Four-wheel Drive
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges. A four-wheel drive vehicle with torque supplied to both axles is described as "all-wheel drive" (AWD). However, "four-wheel drive" typically refers to a set of specific components and functions, and intended off-road application, which generally complies with modern use of the terminology. Definitions Four-wheel-drive systems were developed in many different markets and used in many different vehicle platforms. There is no universally accepted set of terminology that describes the various architectures and functions. The terms used by various manufacturers often reflect marketing rather than engineering considerations or significant technical d ...

Limited-slip Differential
A limited-slip differential (LSD) is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. Early history In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance. The ZF "sliding pins and cams" became available, and one example was the Type B-70 used during the Second World War in the military VWs ( Kübelwagen and Schwimm ...

Differential (mechanical Device)
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 ma ...

Audi Quattro AWD System
Audi AG () is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. As a subsidiary of its parent company, the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, going back to the early 20th century and the initial enterprises (Horch and the ''Audiwerke'') founded by engineer August Horch (1868–1951); and two other manufacturers (DKW and Wanderer), leading to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz. After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company. The company name is based on the Latin translation of the surname of the founder, August Horch. , meaning "listen", becomes in Latin. The four rings of the Audi logo each repr ...

Toyota 4Runner
The Toyota 4Runner is an SUV manufactured by the Japanese automaker Toyota and marketed globally since 1984, across five generations. In Japan, it was marketed as the and was withdrawn from the market in 2009. The original 4Runner was a compact SUV and little more than a Toyota Hilux pickup truck with a fiberglass shell over the bed, but the model has since undergone significant independent development into a cross between a compact and a mid-size SUV. All 4Runners have been built in Japan at Toyota's plant in Tahara, Aichi, or at the Hino Motors (a Toyota subsidiary) plant in Hamura. The name "4Runner" was created by copywriter Robert Nathan with the Saatchi & Saatchi advertising company. The agency held contests to invent new names for Toyota's forthcoming vehicles. The name 4Runner was created as a play on the term "forerunner," since the sport utility vehicle was the first of its kind for Toyota with an emphasis on its 4x4 capability and seating for four.
