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 dif ...

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 diff ...

Transfer Case
A transfer case is a part of the drivetrain of four-wheel-drive, all-wheel-drive, and other multiple powered axle vehicles. The transfer case transfers power from the transmission to the front and rear axles by means of drive shafts. It also synchronizes the difference between the rotation of the front and rear wheels, and may contain one or more sets of low range gears for off-road use. Functions * The transfer case receives power from the transmission and sends it to both the front and rear axles, or just one (usually the rear.) This can be done with gears, hydraulics, or chain drive. On some vehicles, such as four-wheel-drive trucks or vehicles intended for off-road use, this feature is controlled by the driver. The driver can put the transfer case into either "two-wheel-drive" or "four-wheel-drive" mode. This is sometimes accomplished by means of a shifter, similar to that in a manual transmission. On some vehicles, this may be electronically operated by a switch inste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-wheel Drive
Two-wheel-drive (2WD) denotes Motor vehicle, vehicles with a Powertrain, drivetrain that allows two wheels to be driven, and receive Engine power, power and torque from the engine, simultaneously. Four-wheeled vehicles For four-wheeled vehicles (and by extension, vehicles with six, eight, or more wheels), this term is used to describe vehicles that are able to power at most two wheels, referred to as either front-wheel drive, front, or rear-wheel drive, rear-wheel-drive. The term 4x2 is also used, to denote four total wheels with two being driven. Most road vehicles use a 2WD layout due to its lightweight and simplicity. Traction on the road is usually sufficient that the driving force can be reliably transmitted through only two wheels. For vehicles that have part-time four-wheel drive, the term refers to the mode when 4WD is deactivated and power is applied to only two wheels. Two-wheeled vehicles For two-wheeled vehicles such as motorcycles and bicycles, the term is used to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
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 ...

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 ...
