Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power (physics), power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion (mechanics), torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a Rotating spline, splined joint or prismatic joint.

Shaft (mechanical Engineering)
In mechanical engineering, a shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. Types They are mainly classified into two types. * Transmission shafts are used to transmit power between the source and the machine absorbing power; e.g. counter shafts and line shafts. * Machine shafts are the integral part of the machine itself; e.g. crankshaft. *Axle shaft. *Spindle shaft. Materials The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.

Transaxle
A transaxle is single mechanical device which combines the functions of an automobile's transmission (mechanics), transmission, axle, and differential (mechanics), differential into one integrated assembly. It can be produced in both manual transmission, manual and automatic transmission, automatic versions. Engine and drive at the same end Transaxles are nearly universal in all automobile configurations that have the engine placed at the same end of the car as the driven wheels: the front-engine, front-wheel-drive layout, front-engine/front-wheel-drive; rear-engine, rear-wheel-drive layout, rear-engine/rear-wheel-drive; and rear mid-engine, rear-wheel-drive layout, mid-engine/rear-wheel-drive arrangements. Many mid-engine design, mid- and rear-engine design, rear-engined vehicles use a transverse engine and transaxle, similar to a front-wheel-drive unit. Others use a longitudinal engine and transaxle like Ferrari's 1989 Ferrari Mondial#Mondial t, Mondial t which used a "T" ar ...

Transmission (mechanics)
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (industrialist), Louis Renault (who founded Renault, 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 engine, steam-powered devices. Applications of these devices included pumps, mill (grinding), mills and Hoist (device), 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 Horsepower, power output of an interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential (mechanics)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and Analog computer, analogue computers. Differentials can also provide a gear ratio between the input and output shafts (called the "axle ratio" or "diff ratio"). For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear. History Milestones in the design or use of differentials include: * 100 BCE–70 BCE: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by Sponge diving, sponge divers, and modern research suggests that it used a differential gear to determine the angle between the ecliptic positions of the Sun and Moon, and th ...

Autocar Company
The Autocar Company is an American specialist manufacturer of severe-duty, Class 7 and Class 8 vocational trucks, with its headquarters in Birmingham, Alabama. Started in Pittsburgh, Pennsylvania, in October 1897 as a manufacturer of early Brass Era automobiles, and trucks from 1899, Autocar is the oldest surviving motor vehicle brand in the Western Hemisphere. Their last cars of their own manufactures were produced in 1911; after that the company continued as a maker of severe-duty trucks. The Autocar Company was taken over 42 years later, in 1953, by White Motor Corporation (established 1900), which made Autocar their top-of-the-line brand for continuing producing heavy-duty industrial trucks. White Motors was in turn taken over 28 years later by Volvo Trucks of Sweden in 1981, with Autocar continuing as a separate division. In 2001, Autocar was acquired by GVW Group, LLC, which revived Autocar as an independent company. Autocar now builds four models of custom-engineered ...

Renault Voiturette
The Renault Voiturette (Renault Little Car) was Renault's first ever produced automobile, and was manufactured between 1898 and 1903. The name was used for five models. The first Voiturettes mounted De Dion-Bouton engines. Continental tires were used for the car, a make still used for several modern Renaults today. Voiturette Type A The first Voiturette was designed by the maker's creator Louis Renault in 1898. The first Voiturette was sold to a friend of Louis' father after going for a ride with Louis along Rue Lepic on December 24, 1898. Twelve more cars were sold that night. The main reason for the man to buy the car was the incredible ability of the car to climb streets without any difficulty and its fuel economy. The car mounted a De Dion-Bouton 1 cylinder engine, which allowed it to reach a top speed of . Voiturette Type B The Type B was basically the same Voiturette. However, the difference was the strange aspect of the car, including a roof and two doors. Louis Renault ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Car
A steam car is a car (automobile) propelled by a steam engine. A steam engine is an external combustion engine (ECE), whereas the gasoline and diesel engines that eventually became standard are internal combustion engines (ICE). ECEs have a lower thermal efficiency, but carbon monoxide production is more readily regulated. The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 that mobile steam engines became a practical proposition. By the 1850s there was a flurry of new steam car manufacturers. Development was hampered by adverse legislation (the UK Locomotive Acts from the 1860s) as well as the rapid development of internal combustion engine technology in the 1900s, leading to the commercial demise of steam-powered vehicles. Relatively few remained in use after the Second World War. Many of these vehicles were acquired by enthusiasts for preser ...

Horse Power (machine)
A horse engine (also called a horse power or horse-power) is a (now largely obsolete) machine for using draft horses to power other machinery. It is a type of animal engine that was very common before internal combustion engines and electrification. Mills driven by horse powers were called horse mills. Horse engines were often portable so that they could be attached to whichever implement they were needed for at the time. Others were built into horse-engine houses. A common design for the horse engine was a large treadmill on which one or more horses walked. The surface of the treadmill was made of wooden slats linked like a chain. Rotary motion from the treadmill was first passed to a planetary gear system, and then to a shaft or pulley that could be coupled to another machine. Such powers were called tread powers, railway powers, or endless-chain powers. Another common design was the horse wheel or sweep power, in which one or several horses walked in a circle, turning a shaf ...

Shaft-driven Bicycle
A shaft-driven bicycle is a bicycle that uses a drive shaft instead of a chain to transmit power from the pedals to the wheel. Shaft drives were introduced in the 1880s, but were mostly supplanted by chain-driven bicycles due to the gear ranges possible with sprockets and derailleurs. Around the 2000s, due to advancements in internal gear technology, a small number of modern shaft-driven bicycles have been introduced. Shaft-driven bikes have a large bevel gear where a conventional bike would have its chain ring. This meshes with another bevel gear mounted on the drive shaft. The use of bevel gears allows the axis of the drive torque from the pedals to be turned through 90 degrees. The drive shaft then has another bevel gear near the rear wheel hub which meshes with a bevel gear on the hub where the rear sprocket would be on a conventional bike, and canceling out the first drive torque change of axis. The 90-degree change of the drive plane that occurs at the bottom bracket a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
