Vauxhall Astra
The Vauxhall Astra is a compact car/small family car (C-segment) that has been sold by Vauxhall since 1980. It is currently produced at Ellesmere Port, Cheshire, England. For its first two generations, the nameplate was applied to right-hand drive versions of the Opel Kadett for use in the UK. Since 1991, Opel has used the Astra nameplate on its B/C-platform. General Motors' Saturn division in the United States also offered a Belgian-built version of the Astra as a captive import from late 2007 until Saturn was discontinued following GM's 2010 bankruptcy. First generation (1980–1984) The Astra name originated with the Vauxhall-badged version of the first front-wheel drive Opel Kadett, which had been launched in 1979 as the Opel Kadett D. This model, which went on sale in March 1980, replaced the Vauxhall Viva in the UK. The last rear-wheel drive Kadett had also formed the basis of the Vauxhall Chevette, which remained in production until 1984. The Astra was Va ...

Vauxhall Cavalier
The Vauxhall Cavalier was a large family car that was sold primarily in the UK by Vauxhall from 1975 to 1995. It was based on a succession of Opel designs throughout its production life, during which it was built in three incarnations. The first generation of Cavalier, launched in 1975 and produced until 1981, was based on the existing Opel Ascona and Opel Manta with a few minor visual differences. The second generation of Cavalier, launched in 1981 and produced until 1988, was launched simultaneously with the identical new generation of Opel Ascona, which was sold across the world in various guises on the General Motors " J-car". The third and final generation of Cavalier, launched in 1988 and produced until 1995, was based on the first generation of Opel Vectra with the same production span. __TOC__ Mark I (1975–1981) Launched with a 1,896 cc engine as a 1976 model in November 1975, the Cavalier was a restyled version of the second generation German Opel Ascona whi ...

Vauxhall Calibra
The Opel Calibra is a coupé, engineered and produced by the German automaker Opel between 1989 and 1997. In the United Kingdom, where it remained on sale until 1999, it was marketed under the Vauxhall brand as the Vauxhall Calibra. It was also marketed as the Chevrolet Calibra in South America by Chevrolet, and the Holden Calibra in Australia and New Zealand by Holden. The Calibra was introduced to belatedly replace the Manta and to counter the Japanese sporting coupés of the period. It employs the running gear of the first generation Opel Vectra, which had been launched in October 1988. Calibra production was based in the Opel factory in Rüsselsheim, Germany, and the Valmet Automotive factory in Uusikaupunki, Finland, where production was consolidated in November 1995. The Calibra was initially only available with front-wheel drive, but from November 1990, four wheel drive became available. Design The Opel Calibra was styled by GM's designer Wayne Cherry, and ...

DOHC
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel Vectra
The Opel Vectra is a mid-size car (large family car) that was engineered and produced by the German automaker Opel from 1988 until 2010. Available in saloon, hatchback and estate body styles, the Vectra was also sold by the Vauxhall marque in the United Kingdom as the Vauxhall Cavalier from 1988 to 1995 and then as the Vauxhall Vectra from 1995 to 2008, and it was also sold by Holden in Australia as the Holden Vectra, by Chevrolet in Latin America as the Chevrolet Vectra. The Vectra was introduced in October 1988 as a replacement for the Opel Ascona, and was itself replaced in November 2008 by the new Opel Insignia, the nameplate spanning three generations and almost twenty one years. Vectra A (1988–1995) The first generation Vectra, known as the Vectra A, was introduced in October 1988 for the 1989 model year, as a four door notchback saloon, replacing the Opel Ascona C. A five-door hatchback version arrived in March 1989, and a coupé based on the Vectra, called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel Astra
The Opel Astra is a compact car/small family car (C-segment) developed and produced by the German automaker Opel since 1991, currently at its sixth generation. It was first launched in September 1991 as a direct replacement to the Opel Kadett. , the car slots between the smaller Corsa supermini and the larger Insignia large family car. Initially, the Astra was available in hatchback, saloon, and estate (station wagon; known as the Astra Caravan, later the Sports Tourer) forms. A panel van (sedan delivery; Astravan) and a convertible (Astra Cabrio) also appeared in the early 1990s. These body styles were later followed by a coupé (the Astra GTC) in 2004, and the sporty Astra OPC appeared in 2005. The Twin Top retractable hardtop convertible replaced the soft top convertible in 2006, while the Caravan was renamed to Astra Sports Tourer since 2009. The Astra is branded the Vauxhall Astra in the United Kingdom. It was rebadged and sold as the Saturn Astra in North Ameri ...

Opel Kadett
The Opel Kadett is a small family car produced by the German automobile manufacturer Opel from 1936 until 1940 and then from 1962 until 1991 (the Cabrio continued until 1993), when it was succeeded by the Opel Astra. Kadett I (1936–1940) The first Opel car to carry the Kadett name was presented to the public in December 1936 by Opel's Commercial-Technical director, Heinrich Nordhoff, who would in later decades become known for his leadership role in building up the Volkswagen company. The new Kadett followed the innovative Opel Olympia in adopting a chassis-less unibody construction, suggesting that like the Vauxhall 10 introduced in 1937 by Opel's English sister-company, the Opel Kadett was designed for high volume low-cost production.

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Bell Housing
Bell housing or bellhousing is a colloquial/slang term for the portion of the transmission that covers the flywheel and the clutch or torque converter of the transmission on vehicles powered by internal combustion engines. This housing is bolted to the engine block and derives its name from the bell-like shape that its internal components necessitate. The starter motor is usually mounted here, and engages with a ring gear on the flywheel. On the opposite end to the engine is usually bolted to the gearbox. The use of different bellhousings on a transmission allows the same transmission to be used on multiple engines in multiple applications. However, on some transmissions, the bellhousing is a nonremovable part of the transmission case. This is particularly true with front wheel drive transmissions, which are much shorter than conventional rear wheel drive transmissions.

Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
