PDK (Porsche Doppelkupplungsgetriebe)
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears. The first DCT to reach production was the ''Easidrive'' automatic transmission introduced on the 1961 Hillman Minx mid-size car. This was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf R32. Since the late 2000s, DCTs have become increasingly widespread, and have supplanted hydraulic automatic transmissions in various models of cars ...

Fortschritt ZT 320
Fortschritt ZT 320 is a series of agricultural tractors made by the East German manufacturer VEB Traktorenwerk Schönebeck. It was produced from 1983 to 1990, and succeeded the ZT 300 series. Unlike its predecessor, the ZT 320 series came in only two models, the rear-wheel drive ''ZT 320'', and the all-wheel drive ''ZT 323''. Concept The ZT 320 series was meant to be an upgrade of the existing ZT 300 series, and therefore, many at the time not obsolete ZT 300 components, like the axles, frame, and steering system, were carried over to the ZT 320 series. The main parts that were supposed to receive an upgrade were, amongst other things, the three-point linkage, powertrain, driver's cab, and to fulfill contemporary regulations, the braking system. Compared to the ZT 300 series, the ZT 320 was also designed to be much more versatile. With its upgraded braking system, it can pull trailers with a mass of up to 30,000 kg, ...

The Audi Quattro is a road and rallying, rally car, produced by the Germany, German automotive industry, automobile manufacturer Audi, part of the Volkswagen Group. It was first shown at the Geneva Motor Show#1980, 1980 Geneva Motor Show on 3 March. Production continued through 1991. Background The word ''quattro'' is derived from the Italy, Italian word for "four" to represent the fact that the vehicle delivers power to all four wheels. The name has also been used by Audi to refer to the quattro (four-wheel-drive system), quattro four-wheel-drive system, or any four-wheel-drive version of an Audi model. The original Quattro model is also commonly referred to as the Ur-Quattro - the "wikt:Ur-, Ur-" (German language, German for "primordial", "original", or "first of its kind") is an augmentative prefix.

World Sportscar Championship
The World Sportscar Championship was the world series run for sports car racing by the FIA from 1953 to 1992. The championship evolved from a small collection of the most important sportscar, endurance, and road racing events in Europe and North America with dozens of gentleman drivers at the grid, to a professional racing series where the world's largest automakers spent millions of dollars per year. The official name of the series changed throughout the years, however it has generally been known as the World Sportscar Championship from its inception in 1953. The World Sportscar Championship was, with the Formula One World Championship, one of the two major world championships in circuit motor racing. In 2012 the World Sportscar Championship was revived and renamed as the World Endurance Championship. Races The most famous event was the 24 Hours of Le Mans which was the part of the championship in every season except of the 1956, 1975– 79 and 1989– 90 seasons. Th ...

Porsche 956
The Porsche 956 was a Group C sports-prototype racing car designed by Norbert Singer and built by Porsche in 1982 for the FIA World Sportscar Championship. It was later upgraded to the 956B in 1984. In 1983, driven by Stefan Bellof, this car established a record that would stand for 35 years, lapping the famed 20.832 km (12.93 mi) Nürburgring Nordschleife in 6:11.13 during qualifying for the 1000 km Sports Car race. The record was finally surpassed by Timo Bernhard in a derestricted Porsche 919 Evo on 29 June 2018. Development Built to comply with the championship's new Group C regulations which were introduced in 1982, the car was a replacement for Porsche's successful 936 model which competed in the previous Group 6 category of the World Championship. The project began in June 1981, and the first prototype chassis was completed on March 27, 1982, in time for the beginning of the World Championship season.

Solenoid
upright=1.20, An illustration of a solenoid upright=1.20, Magnetic field created by a seven-loop solenoid (cross-sectional view) described using field lines A solenoid () is a type of electromagnet formed by a helix, helical coil of wire whose length is substantially greater than its diameter, which generates a controlled magnetic field. The coil can produce a uniform magnetic field in a volume of space when an electric current is passed through it. The term ''solenoid'' was coined in 1823 by André-Marie Ampère. The helical coil of a solenoid does not necessarily need to revolve around a straight-line axis; for example, William Sturgeon's electromagnet of 1824 consisted of a solenoid bent into a horseshoe shape (not unlike an arc spring). Solenoids provide magnetic focusing of electrons in vacuums, notably in television camera tubes such as vidicons and image orthicons. Electrons take helical paths within the magnetic field. These solenoids, focus coils, surround nearly th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small ...

Electromagnetic Clutch
Electromagnetic clutches operate electrically but transmit torque mechanically. This is why they used to be referred to as electro-mechanical clutches. Over the years, EM became known as electromagnetic versus electro-mechanical, referring more about their actuation method versus physical operation. Since the clutches started becoming popular over 60 years ago, the variety of applications and clutch designs has increased dramatically, but the basic operation remains the same today. Single-face clutches make up approximately 90% of all electromagnetic clutch sales. Electromagnetic clutches are most suitable for remote operation since no mechanical linkages are required to control their engagement, providing fast, smooth operation. However, because the activation energy dissipates as heat in the electromagnetic actuator when the clutch is engaged, there is a risk of overheating. Consequently, the maximum operating temperature of the clutch is limited by the temperature rating of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citroën Traction Avant
The Citroën Traction Avant () is the world’s first unibody front-wheel-drive car. A range of mostly 4-door saloons and executive cars, were made with four or six-cylinder engines, produced by the French manufacturer Citroën from 1934 to 1957. Approximately 760,000 units were produced. Whilst front-wheel drive and independent suspension had been established in the mass market by Auto Union and subsequently others some years before, the Traction Avant pioneered mass-production of a crash resistant, unitary, monocoque body. Additionally, the car was also an early adopter of rack and pinion steering. Although the car's name emphasized its front-wheel drive power delivery ("Traction Avant" literally means “front traction”), the car stood out at least as much by its much lower profile and stance – made possible by the absence of a separate chassis under the car's unitary body – sharply distinguishing it visually from its contemporaries.
