Dropped Axle
A dropped axle is the axle of a vehicle that is bent upwards towards the ends, i.e. the centre is 'dropped'. This gives two advantages: the centre of gravity of the bodywork is lowered relative to the wheels, which improves stability; secondly the wheels may be of larger diameter, giving a smoother ride over a rough surface. Dropped axles were first used for carts: light two-wheeled horse-drawn vehicles. Their introduction represents one of the safety improvements from the high and unstable dog cart or jaunting car to the lower and more stable governess cart. Their ultimate development was in the float or milk float, where a dropped axle was used to give a low load bed for easy loading of churns or similar unstable liquid cargo. Dropped axles were made of forged wrought iron. Although wood was widely used for axles, owing to its lightness, it could not easily be shaped with the sharp curves required to drop an axle. Shaping such an axle by sawing or cutting would place an area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bugatti Type 37 Front
Automobiles Ettore Bugatti was a German then French manufacturer of high-performance automobiles. The company was founded in 1909 in the then-German city of Molsheim, Alsace, by the Italian-born industrial designer Ettore Bugatti. The cars were known for their design beauty and for their many race victories. Famous Bugatti automobiles include the Type 35 Grand Prix cars, the Type 41 "Royale", the Type 57 "Atlantic" and the Type 55 sports car. The death of Ettore Bugatti in 1947 proved to be a severe blow for the marque, and the death of his son Jean Bugatti in 1939 meant that there was no successor to lead the factory. No more than about 8,000 cars were made. The company struggled financially, and it released one last model in the 1950s before eventually being purchased for its airplane parts business in 1963. In 1987, an Italian entrepreneur bought the brand name and revived it as Bugatti Automobili SpA. Under Ettore Bugatti Founder Ettore Bugatti was born in Milan, I ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portal Axle
Portal axles (or portal gear lifts) are an off-road vehicle suspension and drive technology where the axle tube or the half-shaft is off-set 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. This 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 halfshafts to drive the same power but at reduced torque (by using higher shaft speed). This reduces load on the axle crownwheel 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 normal layout, portal axles enable the vehicle to gain a higher ground clearance, as both the axle tube and differential casing are tucked up hi ...

Suspension Travel
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ettore Bugatti
Ettore Arco Isidoro Bugatti (15 September 1881 – 21 August 1947) was an Italian-born French automobile designer and manufacturer. He is remembered as the founder and proprietor of the automobile manufacturing company Automobiles E. Bugatti, which he founded in 1909 in the then German town of Molsheim in the Alsace region of what is now France. Bugatti died in Paris, and is buried in Dorlisheim, France. Family origin and early life Bugatti was born into an artistic family with its origin in Milan, Italy. He was the elder son of Carlo Bugatti (1856–1940), an important Italian Art Nouveau furniture and jewellery designer, and his wife Teresa Lorioli. His younger brother, Rembrandt (1884–1916), was a renowned animal sculptor. His aunt, Luigia Bugatti, was the wife of the painter Giovanni Segantini. His paternal grandfather, Giovanni Luigi Bugatti, was an architect and sculptor. Bugatti's father intended that he follow a conventional technical apprenticeship with one of th ...

U Bolt
A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. U-bolts have primarily been used to support pipework Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. Industrial process piping (and accompa ..., pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting. U-bolts are also used to hold ropes together. For example, a 40 Nominal Bore U-bolt would be asked for by pipe work engineers, and only they would know what that meant. In reality, the 40 nominal bore part bears little resemblance to the size and dimensions of the U-bolt. The nominal bore of a pipe is actually a measurement of the inside diameter of the pipe. Engineers are interested in this because they design a pipe b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stress Riser
In solid mechanics, a stress concentration (also called a stress raiser or a stress riser) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such as nicks and scratches. The degree of concentration of a discontinuity under typically tensile loads can be expressed as a non-dimensional stress concentration factor K_t, which is the ratio of the highest stress to the nominal far field stress. For a circular hole in an infinite plate, K_t = 3. The stress concentration factor should not be confused with the stress intensity factor, which is used to define the effect of a crack on the stresses in the region around a crack tip. For ductile material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
H Girder
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an or -shaped cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred. History The method of producing an I-beam, as rolled from a single piece of wrought iron, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halfshaft
An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating around the axle. In the former case, bearings or bushings are provided at the mounting points where the axle is supported. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle. Sometimes, especially on bicycles, the latter type axle is referred to as a ''spindle''. Terminology On cars and trucks, several senses of the word ''axle'' occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an ''axle'' or ''axle shaft''. However, in looser usage, an entire assembly including the surrounding axle housing (typically a casting) is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam 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 four-wheel-drive vehicles. In most automobiles, beam axles have been replaced with front and rear independent suspensions. Implementation With a beam axle the camber angle between the wheels is the same no matter where it is in the travel of the suspension. A beam axle's fore & aft location is constrained by either: trailing arms, semi-trailing arms, radius rods, or leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage or 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. The Twist-beam rear suspension is a similar suspension desi ...

T-bucket Front Axle
A T-bucket (or Bucket T) is a hot rod, based on a Ford Model T built from 1915 to 1927, but extensively modified. T-buckets were favorites for greasers. History Model Ts were hot-rodded and customized from the 1920s on, but the T-bucket was specifically created and named by Norm Grabowski in the 1950s. This car was named ''Lightning Bug'', better known as the ''Kookie Kar'', after being redesigned by Grabowski and appearing in the TV show ''77 Sunset Strip'', driven by character Gerald "Kookie" Kookson. The exposure it gained led to numerous copies being built. A genuine T-bucket has the two-seater body of a Model T roadster (with or without the turtle deck or small pickup box), this "bucket"-shaped body shell giving the cars their name. A Model T-style radiator is usually fitted, and even these can sometimes be barely up to the task of cooling the large engines fitted. Windshields, when fitted, are vertical glass like the original Model T. Today, T-buckets remain common. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
