Transfer Box
A transfer case is an intermediate gearbox that transfers power from the transmission (mechanics), transmission of a motor vehicle to the driven axles of four-wheel-drive, all-wheel-drive, and other multi-axled on- and off-road machines. A part of the vehicle's drivetrain, it employs drive shafts to mechanically deliver motive power. The transfer case also synchronizes the difference between the rotation of the front and rear wheels (only high-speed 4wd-Awd systems), and may contain one or more sets of gear ratio, low range gears for off-road use. Functions The transfer gearbox (a secondary transmission system) receives power from the transmission (mechanical device), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Driveline Windup
Driveline windup is also known as "axle binding" or "driveline binding". Mechanical components in the drivetrain of vehicles may bind and wear, which may occur when tires of varying sizes are used on one vehicle. It is a particular issue in Four-wheel drive, 4WD cars with tires having varied Tire tread, tread patterns or brands. Despite marked size, different brands often differ in actual size. Even if both front and rear are the same brand, and marked with the same size they may still differ in actual size. A pull to the right or left when driving or braking could trigger windup caused by mismatched tire tread/sizes. H-drive Heavy off-road vehicles using Six-wheel drive, 6×6 or Eight-wheel drive, 8×8 may use a H-drive drivetrain. These are particularly prone to driveline windup. H-drives do not use axles but rather individual wheel stations, carried on a punt chassis, punt or backbone chassis. A single differential (mechanical device), differential splits the drive into ...

New Venture Gear
New Venture Gear was an automobile and light truck transmission company that was started in 1990 as the first-ever joint venture between any of the Big Three U.S. automakers. General Motors and Chrysler Corporation were the participants. Operation and management of Chrysler's New Process Gear plant in Syracuse, New York, and GM's underutilized Hydramatic transmission plant in Muncie, Indiana, were shifted to New Venture Gear Company. History Founding plant histories Hydramatic Muncie In 1902, Thomas W. Warner formed the Warner Gear Company in Muncie, Indiana, to manufacture automobile parts, steering, and transmission gears. In 1919, General Motors purchased the T. W. Warner Company, including its land and buildings. In 1920, GM reopened the plant under the name Muncie Products to manufacture transmissions and steering gear for their Oakland, Pontiac, Oldsmobile, Chevrolet, and GMC Truck divisions. In 1932, GM closed the Muncie Products plant and consolidated operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jeep Four-wheel-drive Systems
Jeep uses a variety of four-wheel drive systems on their vehicles. These range from basic part-time systems that require the driver to move a control lever to send power to four wheels, to permanent four-wheel systems that monitor and sense traction needs at all four wheels automatically under all conditions. Summary ;Notes Command-Trac Command-Trac Command-Trac was first introduced using the NP208 transfer case in the full-size Jeeps (SJ series) in 1980. The drive modes are the same as with the Dana 18 and 20 transfer cases: 2Hi, 4HI PT, and 4LO PT. The 4WD modes are not for use on high-traction surfaces such as dry roads. The NP208 was used through at least 1987. More commonly, ''Command-Trac'' is used to refer to the NP/NV-231 or NP-207 transfer cases introduced along with the Jeep Cherokee (XJ) in 1984. The system offers a chain-driven, aluminum, "shift-on-the-fly" transfer case. The "shift-on-the-fly" feature provides manual ease and assist while engaging 4WD. ''Com ...

Transmission (mechanical Device)
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (who founded Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam-powered devices. Applications of these devices included pumps, mills and hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations. Automobiles Since the torque and power output of an internal combustion engine (ICE) varies with its rpm, automobiles powered by ICEs require multi ...

Clutch
A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's input shaft is typically attached to a motor, while the clutch's output shaft is connected to the mechanism that does the work. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission. By disengaging the clutch, the engine speed (RPM) is no longer determined by the speed of the driven wheels. Another example of clutch usage is in electric drills. The clutch's input shaft is driven by a motor and the output shaft is connected to the drill bit (via several intermediate components). The clutch allows the drill bit to either spin at the same speed as the motor (clutch engaged), spin at a lower speed than the motor (clutch slipping) or remain stationary while the motor is spinning (clutch disengaged). Types Dry clutch A ''dry clutch'' uses dry friction to transfer power from the input shaft to the output shaft, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMC And Jeep Transmissions
Vehicles made by American Motors Corporation (AMC) and Jeep incorporated a variety of transmissions and transfer case systems. This article covers transmissions used in the following vehicle models and years: * All American Motors (AMC) passenger cars, 1954-1988 * Jeep Cherokee XJ (1984–2001) * Jeep Comanche (1986-1992) * Jeep CJ (1976–1986) * Jeep Grand Cherokee WJ (1999–2004) * Jeep Grand Cherokee ZJ (1993–1998) * Jeep Wagoneer/Grand Wagoneer (1963–1993) * Jeep Wrangler YJ (1987–1995) Transmissions Transmissions used in later AMC vehicles came with either a 21- spline or a 23-spline output shaft. Transmissions coupled to four-cylinder engines typically used 21-spline output shafts. The 23-spline manual transmission was universal in the Eagle lines and was generally used with six-cylinder applications. All transfer cases were available with inputs matching either 21- or 23-spline shafts, making transmission swaps possible among various models and years. However, ...

Locking Hubs
Locking hubs, also known as free wheeling hubs are fitted to some (mainly older) four-wheel drive vehicles, allowing the front wheels to rotate freely when disconnected (unlocked) from the front axle. This is done to reduce the mechanical resistance of the front-portion of the drivetrain when four-wheel drive is not in use. The hub, along with the wheel, is designed to engage (lock) onto the axle, to be powered by the drivetrain in four-wheel drive; or the hub can disengage (unlock) from the axle when four-wheel drive is not needed, thus allowing the front wheels to rotate freely within the hub. The hub is a component where the wheel is directly mounted to, and is outside the axle. The benefits of unlocking hubs for normal road use are mainly found in increased fuel efficiency. When the front hubs are locked, even if no power is sent to the front axle (by means of a transfer case), the turning of the wheels will still spin the front axle, differential, and driveshaft, which puts ...

Jeep
Jeep is an American automobile brand, now owned by multi-national corporation Stellantis. Jeep has been part of Chrysler since 1987, when Chrysler acquired the Jeep brand, along with other 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.
