De Dion Tube
De Dion rear axle A de Dion axle is a form of non-independent automobile suspension. It is a considerable improvement over the swing axle, Hotchkiss drive, or live axle. Because it plays no part in transmitting power to the drive wheels, it is sometimes called a "dead axle".Setright, p.515. A powered de Dion suspension uses universal joints on both ends of its driveshafts (at the wheel hubs and at the differential), and a solid tubular beam to hold the opposite wheels in parallel. Unlike an anti-roll bar, a de Dion tube is not directly connected to the chassis, and is not intended to flex. In suspension geometry it is a beam axle suspension. History The de Dion axle was named after Comte Jules-Albert de Dion, founder of French automobile manufacturer De Dion-Bouton. The axle, however, was invented around 1894 by co-founder Charles Trépardoux, Georges Bouton's brother-in-law, for use on the company's steam tricycles. G.N. Georgano, p. 27.

De Dion-Bouton
De Dion-Bouton was a French automobile manufacturer and railcar manufacturer, which operated from 1883 to 1953. The company was founded by the Marquis Jules-Albert de Dion, Georges Bouton, and Bouton's brother-in-law Charles Trépardoux. Steam cars The company was formed in 1883 after de Dion saw a toy locomotive in a store window in 1881 and asked the toymakers to build another. Engineers Bouton and Trépardoux had been eking out a living with scientific toys at a shop in the Passage de Léon, near the rue de la Chapelle in Paris.Wise, p. 510. Trépardoux had long dreamed of building a steam car, but neither he nor Bouton could afford it. De Dion, already inspired by steam in the form of railway locomotives,Georgano, p. 27. and with ample money, agreed to back them, and Trépardoux et Cie was formed in Paris in 1883. That became the De Dion-Bouton automobile company, the world's largest automobile manufacturer for a time, well known for the quality, reliability, and du ...

Alfa Romeo
Alfa Romeo Automobiles S.p.A. () is an Italian carmaker known for its sports-oriented vehicles, strong auto racing heritage, and iconic design. Headquartered in Turin, Italy, it is a subsidiary of Stellantis Europe and one of 14 brands of multinational automotive company Stellantis. Founded on 24 June 1910 in Milan, Italy as A.L.F.A.—an acronym for ''Anonima Lombarda Fabbrica Automobili''—the company was established by Cavaliere Ugo Stella to acquire the assets of the ailing Italian subsidiary of French carmaker Darracq, of which he had been an investor and manager. Its first car was the 24 HP, designed by Giuseppe Merosi, which became commercially successful and participated in the 1911 Targa Florio endurance race. In August 1915, ALFA was acquired by Neapolitan entrepreneur and engineer Nicola Romeo, who vastly expanded the company's portfolio to include heavy machinery and aircraft engines. In 1920, the company's name was changed to Alfa Romeo, with the Torpedo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rover P6
The Rover P6 series (named as the 2000, 2200, or 3500, depending on engine displacement) is a Sedan (automobile), saloon car produced by Rover Company, Rover and subsequently British Leyland from 1963 to 1977 in Solihull, West Midlands, England, UK. The P6 was the first winner of the European Car of the Year award. Development The P6 was announced on 9 October 1963, just before the British International Motor Show, Earls Court Motor Show. The vehicle was marketed first as the Rover 2000 and was a complete "clean sheet" design intended to appeal to a larger number of buyers than earlier models such as the Rover P4, P4 it replaced. Rover had identified a developing market between the standard '1.5-litre' saloon car class (such as the Ford Consul#Ford Consul Mark II .281956.E2.80.931962.29, Ford Consul and the Singer Gazelle#Gazelle IIA to IIIC, Singer Gazelle) and the accepted 'three-litre' large saloon cars (typified by the Wolseley 6/99 and the Vauxhall Cresta#Cresta PA, Vauxha ...

Watt's Linkage
A Watt's linkage is a type of mechanical linkage invented by James Watt in which the central moving point of the linkage is constrained to travel a nearly straight path. Watt's described the linkage in his patent specification of 1784 for the Watt steam engine. Today it is used in automobile suspensions, where it is key to a suspension's kinematics, i.e., its motion properties, constraining the vehicle axle's movement to nearly vertical travel while also limiting horizontal motion. Description Watt's linkage consists of three bars bolted together in a chain. The chain of bars consists of two end bars and a middle bar. The middle bar is bolted at each of its ends to one of the ends of each outer bar. The two outer bars are of equal length, and are longer than the middle bar. The three bars can pivot around the two bolts. The outer endpoints of the long bars are fixed in place relative to each other, but otherwise the three bars are free to pivot around the two joints where t ...

Panhard Rod
A Panhard rod (also called Panhard bar, track bar, or track rod) is a suspension link that provides lateral location of the axle. Invented by the Panhard automobile company of France in the early twentieth century, this device has been widely used ever since. Overview The purpose of automobile suspension is to let the wheels move vertically with respect to the body, while preventing movement forward and backwards (longitudinally), or side to side (laterally). The Panhard rod is a simple device designed to prevent lateral movement. It consists of a rigid bar running sideways in the same plane as the axle, connecting one end of the axle to the car body or |
Universal Joints
A universal joint (also called a universal coupling or U-joint) is a joint (mechanics), joint or coupling connecting rigid shaft (mechanical engineering), shafts whose wikt:axis#Noun, axes are inclined to each other. It is commonly used in shafts that transmit rotation around a fixed axis, rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint. U-joints are also sometimes called by various eponymous names, as follows: * Cardan joint, after Gerolamo Cardano, a polymath of the 16th century who contributed to knowledge of various clever mechanisms, including gimbals * Hooke joint or Hooke's joint, after Robert Hooke, a polymath of the 17th century who contributed to knowledge of various clever mechanisms * Spicer joint, after Clarence W. Spicer and the Spicer Manufacturing Company, who manufactured U joints * Hardy Spicer joint, after the Hardy Spicer b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shock Absorber
A shock absorber or damper is a mechanical or hydraulics, hydraulic device designed to absorb and Damping ratio, damp shock (mechanics), shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically thermal energy, heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in Pneumatic cylinder, air cylinders, the hot air is usually exhausted to the atmosphere. In other types of ...

Camber Angle
Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. It is used in the creation of steering and suspension (vehicle), suspension. If the top of the wheel is further out than the bottom (that is, tilted away from the axle), it is called positive camber; if the bottom of the wheel is further out than the top, it is called negative camber. Effect on handling Camber angle alters the Automobile handling, handling qualities of some suspension designs; in particular, negative camber improves grip in corners especially with a Double wishbone suspension#Short long arms suspension, short long arms suspension. This is because it places the tire at a better angle to the road, transmitting the Centrifugal force#Examples, centrifugal forces through the vertical plane of the tire rather than through a Shear strength, shear force across i ...

Unsprung Weight
The unsprung mass (colloquially unsprung weight) of a vehicle is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them. This contrasts with the sprung mass (or weight) supported by the suspension, which includes the body and other components within or attached to it. Components of the unsprung mass include the wheel axles, wheel bearings, wheel hubs, tires, and a portion of the weight of driveshafts, springs, shock absorbers, and suspension links. Brakes that are mounted inboard (i.e. as on the drive shaft, and not part of the wheel or its hub) are part of a vehicle's sprung mass. Effects The unsprung mass of a typical wheel/tire combination represents a trade-off between the pair's bump-absorbing/road-tracking ability and vibration isolation. Bumps and surface imperfections in the road cause tire compression, inducing a force on the unsprung mass. The unsprung mass then reacts to this force with movement of its ...
