M151 ¼-ton 4×4 Utility Truck
The Ford Motor Company, Ford M151, or officially: Truck, Utility, ¼-Ton, 4×4, was the successor to the Korean War Willys M38, M38 and Willys M38A1, M38A1 Jeep Military light utility vehicle, Light Utility Vehicles. Despite being a clean-sheet redesign, it almost completely retained the same vehicle concept, dimensions and weight. But contrary to all prior U.S. -ton jeeps, based on the 1941, World War II Willys MB, Willys designs, the M151 has a unibody, unitary body and frame, and pioneered replacing Leaf spring, leaf-sprung Beam axle, rigid, live axles front and fear, with all-around independent suspension and coil springs. The M151's four inches (10 cm) increased wheelbase, and 2 inch (5 cm) wider body and tracks, combined with the benefits of its integrated body, gave just enough extra space than the cramped prior jeeps, as well as a more planted stance, with greater side-slope stability. During its decades long service-life, a considerable number of updates a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ford Motor Company
Ford Motor Company (commonly known as Ford) is an American multinational corporation, multinational automobile manufacturer headquartered in Dearborn, Michigan, United States. It was founded by Henry Ford and incorporated on June 16, 1903. The company sells automobiles and commercial vehicles under the List of Ford vehicles, Ford brand, and luxury cars under its Lincoln Motor Company, Lincoln brand. The company is listed on the New York Stock Exchange under the single-letter ticker symbol F and is controlled by the Ford family (Michigan), Ford family. They have minority ownership but a plurality of the voting power. Ford introduced methods for large-scale manufacturing of cars and large-scale management of an industrial workforce using elaborately engineered manufacturing sequences typified by moving assembly lines. By 1914, these methods were known around the world as Fordism. Ford's former British subsidiaries Jaguar Cars, Jaguar and Land Rover, acquired in 1989 and 2000, r ...

Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeep CJ
The Jeep CJ models are a series and a range of small, open-bodied off-road vehicles and compact pickup trucks, built and sold by several successive incarnations of the Jeep automobile marque from 1945 through 1986. The 1945 Willys "Universal Jeep" was the world's first mass-produced civilian four-wheel drive car. In 1944, Willys-Overland, the primary manufacturer of the World War II military Jeep, built the first prototypes for a commercial version – the CJ, short for "civilian Jeep". The design was a direct evolution from the wartime Jeep, but the most obvious change was adding a tailgate, and relocating the spare wheel to the side. Also, besides adding basic civilian amenities and options and legally-compliant lighting, the CJ required a sturdier drivetrain than the wartime model, because the targeted rural buyers would expect years of durability, instead of mere weeks as during WWII. From then on, all CJ Jeeps consistently had a separate body and frame, rigid live axles w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live Axle
A beam axle, rigid axle, or solid axle is a dependent suspension design in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically, they have also been used as front axles. In most automobiles, beam axles have been replaced with front (IFS) and rear independent suspensions (IRS). Implementation With a beam axle, the camber angle between the wheels is the same regardless of its location in the travel of the suspension. A beam axle's location in the fore and aft directions is constrained by one of several suspension components, including trailing arms, semi-trailing arms, radius rods, and leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage, a Watt's linkage, or some other arrangement, most commonly by the leaf springs. Shock absorbers and either leaf springs, coil springs, or air bags are used to control vertical movement. Li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Frame
A vehicle frame, also historically known as its ''chassis'', is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism. Until the 1930s, virtually every car had a structural frame separate from its body, known as ''body-on-frame'' construction. Both mass production of completed vehicles by a manufacturer using this method, epitomized by the Ford Model T, and supply of rolling chassis to coachbuilders for both mass production (as by Fisher Body in the United States) and to smaller firms (such as Hooper (coachbuilder), Hooper) for bespoke bodies and interiors was practiced. By the 1960s, unibody construction in passenger cars had become common, and the trend towards building unibody passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most Pickup truck, pickups continue to use a separate frame as their chassis. Functions The main functions of a frame in a motor vehicle ...

Kaiser Motors
Kaiser Motors (formerly Kaiser-Frazer) Corporation made automobiles at Willow Run, Michigan, United States, from 1945 until 1953. In 1953, Kaiser merged with Willys, Willys-Overland to form Willys Motors Incorporated, moving its production operations to the Willys plant at Toledo, Ohio, where the company continued to build automobiles under the Kaiser marque including the Kaiser Darrin until 1955. Their South American operations continued to build passenger cars well up into the 1960s. The company changed its name to Kaiser Jeep Corporation in 1963. History The Kaiser-Frazer Corporation was established in August 1945 as a joint venture between the Henry J. Kaiser Company and Graham-Paige Motors Corporation. Both Henry J. Kaiser, a California-based industrialist, and Joseph W. Frazer, CEO of Graham-Paige, wanted to get into the automobile business and pooled their resources and talents to do so. Less than a year after Kaiser-Frazer's formation, the first Kaiser and Frazer b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeep Cherokee (XJ)
The Jeep Cherokee (XJ) is a sport utility vehicle developed by American Motors Corporation (AMC) and marketed across a single generation by Jeep in the United States from 1983 (model year 1984) through 2001 — and globally through 2014. It was available in two- or four-door, five-passenger, front-engine, rear- or four-wheel drive configurations. Sharing the name of the original, full-size Jeep Cherokee (SJ), Cherokee SJ model, the 1984 XJ Cherokee was Jeep's first all-new design since the 1963 Jeep Wagoneer (SJ), SJ ''Wagoneer'', as well as the first American off-road vehicle built with fully integrated body-and-frame (unibody) design, and formed the mechanical basis for the Jeep Comanche, Jeep Comanche (MJ) pickup truck (1986–1992). Jeep marketed XJs as ''Sportwagons'', a precursor to the modern sport utility vehicle (SUV) before that term was used. The XJ is credited for spawning competitors, as other automakers noticed the design cannibalizing sales from regular cars, sup ...

Portal Axle
A portal axle (or portal gear lift) is an off-road vehicle suspension and drive technology where the axle tube or the half-shaft is offset from – usually above – the center of the wheel hub and where driving power is transferred to each wheel via a simple gearbox, built onto each hub. It gives two advantages: ground clearance is increased, particularly beneath the low-slung differential housing of the main axles — and secondly, any hub reduction gearing allows the axle half shafts to drive the same power but at reduced torque (by using higher shaft speed). This reduces load on the axle crown wheel and differential. The portal gear configuration is also sometimes called a ''drop gear'' or ''drop gearset'' configuration (which, despite its similarity to the term ''dropped axle'', produces the opposite effect). Description Compared to a normal layout, portal axles enable the vehicle to gain higher ground clearance, as both the axle tube and differential (mechanics), different ...

Humvee
The High Mobility Multipurpose Wheeled Vehicle (HMMWV; colloquial: Humvee) is a family of Military light utility vehicle, light, four-wheel drive Military vehicle#Military trucks, military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the Willys MB, original jeep, and others such as the Vietnam War-era M151 ¼-ton 4×4 utility truck, M151 Jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations. The Humvee saw widespread use in the Gulf War of 1991, where it navigated the desert terrain; this usage helped to inspire civilian Hummer versions. The vehicle's original unarmored design was later seen to be inadequate and was found to be particularly vulnerable to improvised explosive devices in the Iraq Wa ...

Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...
