NSU RO80
The NSU Ro 80 is a four-door, front-engine executive sedan manufactured and marketed by the West German firm NSU from 1967 until 1977. Noted for innovative, aerodynamic styling by Claus Luthe and a technologically advanced powertrain, the Ro 80 featured a , twin-rotor Wankel engine driving the front wheels through a semi-automatic transmission with an innovative vacuum-operated clutch system. Engine dimensions ( Comotor units): length ; width , height , weight . Power at 6,500 rpm; torque at 3,000 rpm (all figures approximate). The Ro 80 was voted Car of the Year for 1968 and 37,398 units were manufactured over a ten-year production run, all in a single generation. Running gear Other technological features of the Ro 80, aside from the powertrain, were the four-wheel ATE Dunlop disc brakes, which were generally only featured on expensive sports or luxury saloon cars. The front brakes were mounted inboard, reducing the unsprung weight. The suspension was independent on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSU Motorenwerke
NSU Motorenwerke AG, or NSU, was a German manufacturer of automobiles, motorcycles and pedal cycles, founded in 1873. Acquired by Volkswagen Group in 1969, VW merged NSU with Auto Union, creating Audi NSU Auto Union AG, ultimately Audi. The NSU is an abbreviation of the name Neckarsulm. History Origin NSU originated as the "Mechanische Werkstätte zur Herstellung von Strickmaschinen", a knitting machine manufacturer established in 1873 by Christian Schmidt, a technically astute entrepreneur, in the town of Riedlingen on the Danube. The business relocated in 1880 to Neckarsulm. There followed a period of rapid growth and in 1886, the company began to produce bicycles, the first of them a 'high wheeler' or 'Penny-farthing' branded as the "Germania". By 1892, bicycle manufacturing had completely replaced knitting machine production. At about this time, the name NSU appeared as a brand name. The first NSU motorcycle appeared in 1901, followed by the first NSU car in 1905. Durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Model Year
The model year (sometimes abbreviated as MY) is a method of describing the version of a product which has been produced over multiple years. The model year may or may not be the same as the calendar year in which the product was manufactured. Automobiles United States and Canada Automobiles in the United States and Canada are identified and regulated by model year, whereas other markets use production date (month/year) to identify specific vehicles, and model codes in place of the "year" (model year) in the North American make-model-year identifier. In technical documents generated within the auto industry and its regulating agencies such as the U.S. National Highway Traffic Safety Administration and United States Environmental Protection Agency and Transport Canada and Environment Canada, the letters ''MY'' often precede the year (as in ''MY2019'' or ''MY93''). Even without this prefix, however, in the North American context it is usually the model year rather than the ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium Carbide
Titanium carbide, Ti C, is an extremely hard ( Mohs 9–9.5) refractory ceramic material, similar to tungsten carbide. It has the appearance of black powder with the sodium chloride (face-centered cubic) crystal structure. It occurs in nature as a form of the very rare mineral () - (Ti,V,Fe)C. It was discovered in 1984 on Mount Arashan in the Chatkal District, USSR (modern Kyrgyzstan), near the Uzbek border. The mineral was named after Ibragim Khamrabaevich Khamrabaev, director of Geology and Geophysics of Tashkent, Uzbekistan. Its crystals as found in nature range in size from 0.1 to 0.3 mm. Physical properties Titanium carbide has an elastic modulus of approximately 400 GPa and a shear modulus of 188 GPa. Titanium carbide is soluble in solid titanium oxide, with a range of compositions which are collectively named "titanium oxycarbide" and created by carbothermic reduction of the oxide. Manufacturing and machining Tool bits without tungsten content can be made of tit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epitrochoid
In geometry, an epitrochoid ( or ) is a roulette traced by a point attached to a circle of radius rolling around the outside of a fixed circle of radius , where the point is at a distance from the center of the exterior circle. The parametric equations for an epitrochoid are: :\begin & x (\theta) = (R + r)\cos\theta - d\cos\left(\theta\right) \\ & y (\theta) = (R + r)\sin\theta - d\sin\left(\theta\right) \end The parameter is geometrically the polar angle of the center of the exterior circle. (However, is not the polar angle of the point (x(\theta),y(\theta)) on the epitrochoid.) Special cases include the limaçon with and the epicycloid with . The classic Spirograph toy traces out epitrochoid and hypotrochoid curves. The paths of planets in the once popular geocentric system of deferents and epicycles are epitrochoids with d>r, for both the outer planets and the inner planets. The orbit of the Moon, when centered around the Sun, approximates an epitrochoid. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocar (magazine)
''Autocar'' (stylized in all caps) is a weekly British automobile magazine published by Haymarket Media Group. It was first published in 1895 and refers to itself as "the world's oldest car magazine". Mark Tisshaw is editor and other team members include Steve Cropley, Rachel Burgess, James Attwood, Matt Prior, Matt Saunders and Felix Page. ''Autocar'' has several international editions, including China, India, New Zealand, and South Africa. History The publication was launched as ''The Autocar'' by Yattendon Group, Iliffe and Son Ltd. "in the interests of the mechanically propelled road carriage" on 2 November 1895 when, it is believed, there were only six or seven cars in the United Kingdom. L. J. K. Setright suggests that the magazine was set up by Henry Sturmey (1857–1930), Henry Sturmey as an organ of propaganda for Harry J. Lawson, founder of the Daimler Company and a journalist on the magazine in its early days. Henry Sturmey stood down as editor of ''The ...

Rack And Pinion
rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert between rotational motion and linear motion: rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. The rack and pinion mechanism is used in rack railways, where the pinion mounted on a locomotive or a railroad car engages a rack usually placed between the rails, and helps to move the train up a steep gradient. It is also used in arbor presses and drill presses, where the pinion is connected to a lever and displaces a vertical rack (the ram). In pipelines and other industrial piping systems, a rack displaced by a linear actuator turns a pinion to open or close a valve. Stairlifts, lock gates, electric gates, and the mechanical steering mechanism of cars are other notable applications. The term "rack and pinion" may be used also when the rac ...
