All-wheel Drive
An all-wheel drive vehicle (AWD vehicle) is one with a powertrain capable of providing power to all its wheels, whether full-time or on-demand. The most common forms of all-wheel drive are: ;1x1 : All unicycles Reflecting one axle with one wheel capable of being powered. ; 2x2 : Some motorcycles and bikes Reflecting two axles with one wheel on each capable of being powered. ; 4×4 (also, four-wheel drive and 4WD): Reflecting two axles with both wheels on each capable of being powered. ; 6×6 (also, six-wheel drive and 6WD): Reflecting three axles with both wheels on each capable of being powered. ;8×8 (also, eight-wheel drive and 8WD): Reflecting four axles with both wheels on each capable of being powered. Vehicles may be either part-time all-wheel drive or full-time: ;On-demand (also, part-time): One axle is permanently connected to the drive, the other is being connected as needed ;Full-time (also, permanent): All axles are permanently connected, with or without a di ...

Jeep Wrangler TJ
Jeep is an American automobile marque, now owned by multi-national corporation Stellantis. Jeep has been part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with remaining assets, from its previous owner American Motors Corporation (AMC). Jeep's current product range consists solely of sport utility vehicles – both crossovers and fully off-road worthy SUVs and models, including one pickup truck. Previously, Jeep's range included other pick-ups, as well as small vans, and a few roadsters. Some of Jeep's vehicles—such as the Grand Cherokee—reach into the luxury SUV segment, a market segment the 1963 Wagoneer is considered to have started. Jeep sold 1.4 million SUVs globally in 2016, up from 500,000 in 2008, two-thirds of which in North America, and was Fiat-Chrysler's best selling brand in the U.S. during the first half of 2017. In the U.S. alone, over 2400 dealerships hold franchise rights to sell Jeep-branded vehicles, and if Jeep were spun off int ...

Land Rover Series
The Land Rover series I, II, and III (commonly referred to as ''series'' Land Rovers, to distinguish them from later models) are compact British off-road vehicles, produced by the Rover Company since 1948, and later by British Leyland. Though inspired by the World War II jeep, the Land Rover immediately distinguished itself from all other cars. From launch, it was the first mass-produced civilian four-wheel drive car with doors on it, and an available hard roof. Contrary to conventional car and truck chassis, it used a sturdier fully box-welded frame. Furthermore, due to post-war steel shortage, and aluminium surplus, Land Rovers received non-rusting aluminium alloy bodies, favouring their longevity. In 1992, Land Rover claimed that 70% of all the vehicles they had built were still in use. Most series models feature leaf-spring suspension with selectable two or four-wheel drive (4WD), however series I's produced between 1948 and mid-1951 had constant 4WD via a freewheel mech ...

Off-road Vehicles
An off-road vehicle, sometimes referred to as an overland or adventure vehicle, is considered to be any type of vehicle which is capable of off-roading, driving on and off Pavement (material), paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension (vehicle), suspension, or even caterpillar tracks. Other vehicles that do not travel on public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, Crane (machine), cranes, backhoes, bulldozers, and golf carts. Off-road vehicles have an enthusiastic following because of their versatility. Several types of motorsports involve racing off-road vehicles. The most common use of these vehicles is for tourism, sightseeing in areas distant from the Pavement (material), pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces. Off-road vehicles ...

Rear-wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19t ...

Individual Wheel Drive
Individual-wheel drive or IWD is a wheeled vehicle with a drivetrain that allows all wheels to receive torque from several motors independent of each other. The term was coined to identify those electric vehicles whereby each wheel is driven by its own individual electric motor. These vehicles inherently have a range of characteristics built-in that are more commonly attributed to four-wheel drive vehicles or vehicles with extensive control systems. These characteristics can be: * Four-wheel drive, i.e. the distribution of available power to all the wheels of a four-wheeled vehicle. * Anti-lock braking system * Anti-skid Other features * If one motor fails, the other motors are powerful enough to drive the vehicle to the nearest repair shop. * Low maintenance. * Easy replacement of motors. * No central gear box. * No mechanical differentials or lockers. * No long and heavy drive shafts. * On the spot, tank/wheelchair-like turning. * On the fly switching between FWD, RWD and ...

H-drive
An H-drive drivetrain is a system used for heavy off-road vehicles with Six-wheel drive, 6×6 or Eight-wheel drive, 8×8 drive to supply power to each wheel station. H-drives do not use axles but rather individual wheel stations, usually carried on a punt chassis. A single differential (mechanical device), differential splits the drive into separate left and right drive shafts, which each run fore and aft inside the bottom corners of the chassis. At each wheel station a bevel gear, bevel box drives the half shaft out to the wheel. Advantages * Each wheel station has independent suspension. * Greater ground clearance than conventional axles, as there is no central housing for the differential and final drive. * Lower unsprung weight as only the halfshafts are carried, not the centre differential of an axle. * Only one differential is required; however, this also requires that final drive to transmit all of the vehicle's torque. * Losing traction with one wheel still retains trac ...

Front-wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the first e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
All-terrain Vehicle
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states, territories and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six-wheel mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Range Rover Classic
The Range Rover Classic is a 4x4, mid-size Sport utility vehicle series produced from 1969 to 1996 – initially by the Rover (later Land Rover) division of British Leyland, and latterly by the Rover Group. The first generation of vehicles produced under the Range Rover name, it was built as a two-door model for its first 11 years, until a four-door also became available in 1981. The Range Rover then successfully moved upmarket during the 1980s, and remarkably debuted in the U.S. as a 17-year old model at the 1987 Los Angeles Auto Show. Availability of the two-door version was restricted from 1984, but it remained in production for some markets until 1994, when the second generation was launched. From that moment, Land Rover rebranded the original model under the term "Range Rover Classic", to distinguish it from its new P38A successor, when the two were briefly built alongside, and applied the name retrospectively to all first-generation Range Rovers.

Viscous Coupling
A viscous coupling is a mechanical device which transfers torque and rotation by the medium of a viscous fluid. Design Rotary viscous couplings with interleaved, perforated plates and filled with viscous fluids are used in automotive systems to transmit torque. The device consists of a number of circular plates with tabs or perforations, fitted very close to each other in a sealed drum. Alternate plates are connected to a driving shaft at one end of the assembly and a driven shaft at the other end. The drum is filled with a dilatant fluid, often silicone-based, to about 80% by volume. When the two sets of plates are rotating in unison, the fluid stays cool and remains liquid. When the plates start rotating at different speeds, the shear effect of the tabs or perforations on the fluid will cause it to heat and become nearly solid because the viscosity of dilatant fluids rapidly increases with shear. The fluid in this state will effectively glue the plates together and transm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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"''. Škoda ...

Subaru Leone
The Subaru Leone is a compact car produced by the Japanese car manufacturer Subaru from 1971 to 1994. The word ''leone'' is Italian for lion. It was released as a replacement for the Subaru 1000 and was the predecessor of the Subaru Impreza. All Leones were powered by the Subaru EA boxer engine. Most cars were equipped with optional four-wheel drive. At the time of its introduction, the Leone was Subaru's top model until 1989, when the larger Legacy was introduced. Although released in Japan and some export markets as the Leone, for many years, this was the only vehicle sold internationally by Subaru where the smaller kei cars Rex, Vivio, R-2, 360, and Sambar were not commonly sold. As a result, in major markets such as Australia, Europe and North America, it was instead identified with a trim level designation, some of which included: DL, GL, GLF, GLF5, GL-10, and RX. The car is thus often referred to simply as the Subaru GL or the Subaru L series. First Generation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
