VAL 206
The VAL 206 is one of the VAL series, an automated guideway transit system manufactured by Matra. Because it uses rubber tires, it is suitable for applications that require high acceleration / deceleration. The 206 classification comes from the fact that the width of the vehicle is . The train is two-car formation. It is unmanned operation, but it can also be operated manually as needed. It was succeeded by the VAL 208. Overview Because of automatic operation, the delay is small, the train density can be increased. On the other hand, since this train is basically a two-car train, it is suitable for low-population areas and medium-sized cities. Interior Although the vehicle is small, the window is large, so it is a car with open feeling. Air conditioning is not installed. Plastics are widely used for many parts, but doors and handrail are made of stainless steel. The color tone inside the car varies depending on the railway operator.

Spiral Bevel Gear
A spiral bevel gear is a bevel gear with helical teeth. The main application of this is in a vehicle differential, where the direction of drive from the drive shaft must be turned 90 degrees to drive the wheels. The helical design produces less vibration and noise than conventional straight-cut or spur-cut gear with straight teeth. A spiral bevel gear set should always be replaced in pairs i.e. both the left hand and right hand gears should be replaced together since the gears are manufactured and lapped in pairs. Handedness A right hand spiral bevel gear is one in which the outer half of a tooth is inclined in the clockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear. A left hand spiral bevel gear is one in which the outer half of a tooth is inclined in the counterclockwise direction from the axial plane through the midpoint of the tooth as viewed by an observer looking at the face of the gear.

Electric Multiple Units Of France
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Orlyval
Orlyval is a light metro shuttle service at Paris's Orly Airport using the Véhicule Automatique Léger (VAL, English: ''automatic light vehicle)'' driverless, rubber-tyred people mover technology. The line, which opened on 2 October 1991, offers free service between the two airport terminal stations, and premium fare service to Antony station, where passengers can connect to the city's RER B trains. Orlyval is the second line to use the VAL technology after the Lille Metro. The line was financed and initially operated by private companies including Matra, the company that developed the VAL technology, along with several international developers. The line was a commercial failure and the operators went bankrupt. RATP Group, the transportation operator for the Paris region, took over the line in 1992. History Orly Airport is the primary airport for domestic flights between Paris and other cities in France. During the 1980s, the only transportation options to the airport were b ...

Lille Metro
The Lille Metro (french: Métro de Lille) is a driverless light metro system located in Lille, France. It was opened on 25 April 1983 and was the first to use the VAL (french: véhicule automatique léger, en, light automated vehicle) system. While often referred to as the first fully automated driverless metro of any kind in the world, the Port Liner in Kobe, Japan predates it by two years. The light metro system is made up of two lines that serve 60 stations, and runs over of route. The system forms part of a multi-modal public transport system covering the Lille metropolitan area, along with buses and trams, operated under the '' Ilevia'' brand. History In the 1960s the decentralisation of the city of Lille was considered; some towns of the Lille region were isolated and were poorly served by existing public transport, while the centre of Lille was congested with traffic and buses. The decentralisation resulted in the creation of the Public Establishment of Lille E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Universal Joint
A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint. U-joints are also sometimes called by various eponymous names, as follows: * Cardan joint, after Gerolamo Cardano, a polymath of the 16th century who contributed to knowledge of various clever mechanisms, including gimbals * Hooke joint or Hooke's joint, after Robert Hooke, a polymath of the 17th century who contributed to knowledge of various clever mechanisms * Spicer joint, after Clarence W. Spicer and the Spicer Manufacturing Company, who manufactured U joints * Hardy Spicer joint, after the Hardy Spicer brand, a successor to the Spicer brand History The main concept of the universal joint is ...

Matra
Matra (an acronym for Mécanique Aviation Traction) was a French industrial conglomerate. During its years of operation, it was engaged in a wide range of business activities, primarily focused around automobiles, bicycles, aeronautics and weaponry. Following the acquisition of vehicle manufacturer Automobiles René Bonnet, the company formed Matra Automobiles during the 1960s and made the Matra brand famous through the production of a range of racing cars and sports cars. Its car division worked closely with other vehicle manufacturers, most significantly Renault, prior to the decline and sale of Matra Automobiles during the early 2000s. In addition to road cars, Matra entered into a wide range of businesses, eventually diversifying into media, weaponry, aeronautics, automobiles, and music distribution. Matra was at one point owned by the Floirat family. Throughout much of the company's existence, French businessman Jean-Luc Lagardère served as the CEO of Matra. During 1988 ...
