Costruzione Italiana Macchine Attrezzi
Costruzione Italiana Macchine Attrezzi (CIMA, "Italian Machine Tool Company") is an Italian gear, powertrain, and transmission manufacturer based in Bologna. CIMA was founded in 1942 as a manufacturer of gear machining equipment before producing its own gears in 1946. Beginning in the 1950s CIMA supplied gears for automobile and motorcycle racing applications, including Scuderia Ferrari, Porsche, Harley-Davidson, Minarelli, and Honda. In 1980 what is now the purchased CIMA, who went on to expand the into more machinery markets as well as marine applications. In the 90s, CIMA expanded its reach to the aeronautical industry and found more success in racing. After advancing their low pressure vacuum carburizing and gas quenching methods in 2002, CIMA developed even higher performance transmissions for road and race applications. Their transaxles are found in many low volume supercars A supercar – also called exotic car – is a loosely defined description of street-legal, hi ...

Società Per Azioni
''Società'' (Italian: ''Society'') was an Italian communist cultural magazine published in Italy between 1945 and 1961. History and profile ''Società'' was founded as a quarterly magazine in Florence in 1945. The founders were Ranuccio Bianchi Bandinelli, Cesare Luporini and Romano Bilenchi. Bandinelli also directed the magazine. In 1948 the magazine became closer to the Italian Communist Party (PCI), but was not published by the party. The headquarters was later moved to Rome, and in 1954 its frequency was switched to bimonthly. ''Società'' featured Italian fiction and poetry and occasionally included some essays on the theater and the cinema. It was one of the publications read by the Italian intellectuals, who had Gramscian Antonio Francesco Gramsci ( , , ; 22 January 1891 – 27 April 1937) was an Italian Marxist philosopher, journalist, linguist, writer, and politician. He wrote on philosophy, political theory, sociology, history, and linguistics. He was a ... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburizing
Carburising, carburizing (chiefly American English), or carburisation is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Depending on the amount of time and temperature, the affected area can vary in carbon content. Longer carburizing times and higher temperatures typically increase the depth of carbon diffusion. When the iron or steel is cooled rapidly by quenching, the higher carbon content on the outer surface becomes hard due to the transformation from austenite to martensite, while the core remains soft and tough as a ferritic and/or pearlite microstructure.Oberg, E., Jones, F., and Ryffel, H. (1989) ''Machinery's Handbook 23rd Edition.'' New York: Industrial Press Inc. This manufacturing process can be characterized by the following key points: It is applied to low-carbon workpieces; workpieces are in contact w ...

Arrinera Hussarya
The Arrinera Hussarya is a sports car project made by Polish automotive manufacturer Arrinera Automotive. It was touted by Arrinera as the first supercar designed and engineered in Poland. It was named after Poland's Hussar cavalry. In 2021, it was announced that according to the latest quarterly report(dated 11.08.21), due to funding problems, the project will not be further developed. Prototype The prototype of Arrinera premiered on 9 June 2011 to shareholders and investors. Some journalists gave the supercar the name "Venocara", although Arrinera Automotive has never officially used that name. It featured scissor doors Scissor doors (also called flap doors, wing doors, beetle-wing doors, turtle doors, switchblade doors, swing-up doors, upswing doors, Lamborghini doors, and Lambo doors) are automobile doors that rotate vertically at a fixed hinge at the front o ... for both the concept car and the production car.

Apollo Arrow
The Apollo Arrow is a mid-engine, 2-seater concept car developed by Apollo Automobil. It was introduced in 2016 at the Geneva Motor Show. Production The Arrow was co-developed by Scuderia Cameron Glickenhaus (SCG) and Apollo Automobil, while Roland Gumpert was CEO of Apollo. It was planned that an Italian company MAT, the company that builds the SCG 003C would be appointed to produce the production version of the car. SCG stated that a production version of the Arrow would consist of a track only version with a V12 engine, code named 'Titan,' in 2017, followed by a road going version called the Apollo S with a twin-turbocharged V8 engine, and that both models will “utilise the chassis technology developed for the SCG003C”, but as of 2018 neither model has reached production stages primarily due to the management of Apollo Automobil focusing on the development of a separate model. Specifications and performance The Arrow concept is powered by a 4.0 L, twin turboc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supercars
A supercar – also called exotic car – is a loosely defined description of street-legal, high-performance sports cars. Since the 2010s, the term hypercar has come into use for the highest performing supercars. Supercars commonly serve as the flagship model within a vehicle manufacturer's line-up of sports cars and typically feature various performance-related technology derived from motorsports. Some examples include the Ferrari 458 Italia, Lamborghini Aventador, and McLaren 720S. In the United States, muscle cars were often referred to as "supercars" during the 1960s. History Europe The Lamborghini Miura, produced from 1966–1973, is often said to be the first supercar. By the 1970s and 1980s the term was in regular use, if not precisely defined. One interpretation up until the 1990s was to use it for mid-engine two-seat cars with at least eight cylinders (but typically a V12 engine), a power output of at least and a top speed of at least . Other interpretations stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automated Manual Transmission
The automated manual transmission (AMT) is a type of transmission for motor vehicles. It is essentially a conventional manual transmission but uses automatic actuation to operate the clutch and/or shift between gears. Many early versions of these transmissions that are semi-automatic in operation, such as ''Autostick'', which automatically control only the clutch — often using various forms of clutch actuation, such as electro-mechanical, hydraulic, pneumatic, or vacuum actuationhttp://hudsonterraplane.com/tech/other/DrivemasterServiceInformation.pdf — but still require the driver's manual input and full control to initiate gear changes by hand. These systems that require manual shifting are also referred to as clutchless manual systems. Modern versions of these systems that are fully automatic in operation, such as ''Selespeed'' and ''Easytronic'', can control both the clutch operation and the gear shifts automatically, by means of an ECU, therefore requiring no manu ...

Sequential Manual Transmission
A sequential manual transmission, also known as a sequential gearbox, or a sequential transmission, is a type of non-synchronous manual transmission used mostly for motorcycles and racing cars. It produces faster shift times than traditional synchronized manual transmissions, and restricts the driver to selecting either the next or previous gear, in a successive order. Design A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter. This restriction avoids accidentally selecting the wrong gear; however, it also prevents the driver from deliberately "skipping" gears. The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. On a sequentia ...

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spur Gear
Spur gears or straight-cut gears are the simplest type of gear. They consist of a cylinder or disk with teeth projecting radially. Viewing the gear at 90 degrees from the shaft length (side on) the tooth faces are straight and aligned parallel to the axis of rotation. Looking down the length of the shaft, a tooth's cross section is usually not triangular. Instead of being straight (as in a triangle) the sides of the cross section have a curved form (usually involute and less commonly cycloidal) to achieve a constant drive ratio. Spur gears mesh together correctly only if fitted to parallel shafts. No axial thrust is created by the tooth loads. Spur gears are excellent at moderate speeds but tend to be noisy at high speeds. Spur gear can be classified into two pressure angles, 20° being the current industry standard and 14½° being the former (often found in older equipment). Spur gear teeth are manufactured as either involute In mathematics, an involute (also known as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...
