Sunbeam S7 And S8
The Sunbeam S7 and S8 are British motorcycles designed by Erling Poppe with styling loosely based on the BMW R75 designs that were acquired as war reparations by BSA (full rights to the Sunbeam brand had been acquired from AMC in 1943). Built in Redditch, the unusual engine layout was similar to that of a car. The engine was a longitudinally mounted inline vertical OHC 500 cc twin based on an experimental 1932 BSA design (the Line-Ahead-Twin - LAT) with coil ignition and wet sump lubrication which, through a dry clutch, drove a shaft drive to the rear wheel. The inline engine made this technologically feasible—horizontally-opposed ("flat") twin engines on BMW motorcycles had already used shaft drives following the system employed by the four cylinder Nimbus since 1918. The early S7 was expensive and over engineered, which is why it is now the most sought-after and commands a premium over the S7 De Luxe and the S8, which were produced with fewer features to reduce costs, ...

Sunbeam Cycles
Sunbeam Cycles made by John Marston Limited of Wolverhampton was a British brand of bicycles and, from 1912 to 1956 motorcycles. On John Marston's death after the First World War it was bought by Nobel Industries, Nobel became ICI. Associated Motor Cycles bought it in 1937; then, BSA bought Sunbeam in 1943. Sunbeam Cycles is most famous for its S7 balloon-tyred shaft-drive motorcycle with an overhead valve in-line twin engine. History Sunbeam Cycles was founded by John Marston, who was born in Ludlow, Shropshire, UK in 1836 of a minor landowning family. In 1851, aged 15, he was sent to Wolverhampton to be apprenticed to Edward Perry as a japanware manufacturer. At the age of 23 he left and set up his own japanning business making any and every sort of domestic article. He did so well that when Perry died in 1871 Marston bought Perry's business and amalgamated it with his own. In 1887 Marston began making bicycles and, on the suggestion of his wife Ellen, he adopted th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears transfer the energy from linear to vertical power, making it very useful in machines widely used in mechanical settings. Introduction Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear ...

Sunbeam Motorcycles
A sunbeam, in meteorological optics, is a beam of sunlight that appears to radiate from the position of the Sun. Shining through openings in clouds or between other objects such as mountains and buildings, these beams of particle-scattered sunlight are essentially parallel shafts separated by darker shadowed volumes. Their apparent convergence in the sky is a visual illusion from linear perspective. The same illusion causes the apparent convergence of parallel lines on a long straight road or hallway at a distant vanishing point. The scattering particles that make sunlight visible may be air molecules or particulates. Crepuscular rays ''Crepuscular rays'' or ''god rays'' are sunbeams that originate when the sun is just below the horizon, during twilight hours. Crepuscular rays are noticeable when the contrast between light and dark is most obvious. Crepuscular comes from the Latin word "crepusculum", meaning twilight. Crepuscular rays usually appear orange because the path t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Worm Drive
A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear. The terminology is often confused by imprecise use of the term ''worm gear'' to refer to the worm, the worm wheel, or the worm drive as a unit. The worm drive or "endless screw" was invented by either Archytas of Terentum, Apollonius of Perga, or Archimedes, the last one being the most probable author.Witold Rybczynski, '' One good turn : a natural history of the screwdriver and the screw''. London, 2000. Page 139. The worm drive later appeared in the Indian subcontinent, for use in roller cotton gins, during the Delhi Sultanate in the thirteenth or fourteenth centuries.Irfan Habib''Economic History of Medieval India, 1200–1500'', page 53 Pearson Education Explanation A gearbox designed using a worm and worm wheel is considerably smaller than on ...

Lanchester Motor Company
The Lanchester Motor Company Limited was a car manufacturer located until early 1931 at Armourer Mills, Montgomery Street, Sparkbrook, Birmingham, and afterwards at Sandy Lane, Coventry England. The marque has been unused since the last Lanchester was produced in 1955. The Lanchester Motor Company Limited is still registered as an active company and accounts are filed each year, although as of 2014 it is marked as "non-trading". The Lanchester company was purchased by the BSA Group at the end of 1930, after which its cars were made by Daimler on Daimler's Coventry sites. So, with Daimler, Lanchester became part of Jaguar Cars in 1960. In 1990 Ford Motor Company bought Jaguar Cars and it remained in their ownership, and from 2000 accompanied by Land Rover, until they sold both Jaguar and Land Rover to Tata Motors in 2008, who created Jaguar Land Rover as a subsidiary holding company for them. In 2013, Jaguar Cars was merged with Land Rover to form Jaguar Land Rover Limited, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaft Drive
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 and 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 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 splined joint or prismatic joint. History The term ''driveshaft'' first appeared during the mid-19th centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
