Berlin Auto Show
The Berlin Motor Show originally started in 1897 in the German capital Berlin as the home of the International Motor Show (''Internationale Automobil-Ausstellung'', IAA) and ran until 1939. From 1951 the IAA eventually became established in Frankfurt. A new bi-annual Motor Show, called ''Autos, Avus, Attraktionen'' (AAA), was established by the Messe Berlin company in 1978. The last show was held in 2000, with the 2002 show cancelled four months prior to the expected 2002 exhibition. History On 30 September 1897, the first IAA was held by the '' Mitteleuropäischer Motorwagenverein'' ("Central European Motor Vehicle Association") at the Hotel Bristol on the Unter den Linden boulevard in Berlin. A total of eight Benz Velo, Lutzmann, Kühlstein, and Daimler motor vehicles were on display. A second motor show was held in 1898 at the exhibition grounds near Lehrter Bahnhof; in 1899 more than 100 exhibitors participated in the third motor show . As the automobile became more known ...

Crank (mechanism)
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning Wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Start ...

Opel Regent
The Opel Regent is a luxury car from the German carmaker Opel introduced in November 1928 and available as a four-door limousine and two-door coupe. The official name was ''Opel 24/110'' (24 Steuer-PS/110 PS nominal). The long ''Regent'' was available from 25,000 Reichsmark, and had an eight-cylinder engine with 6 litre capacity that allowed a top speed of . The Regent is notable for being Opel's most luxurious vehicle and competed with the likes of Rolls-Royce, Bugatti, and Mercedes-Benz. In March 1929, General Motors bought 80% of the share capital of Adam Opel AG. Since GM feared too much competition with the top models of its own brands Cadillac and Buick, the Regent was discontinued. GM purchased back all models that had been purchased and scrapped them in an event described as unique by various automotive historians. This means that no Regent has survived. The name ''Regent'' was later used for the luxury versions of the 1932 Opel Regent 1.8 Litre. However, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Independent Suspension
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together. Most modern vehicles have independent front suspension (IFS). Many vehicles also have an independent rear suspension (IRS). IRS, as the name implies, has the rear wheels independently sprung. A fully independent suspension has an independent suspension on all wheels. Some early independent systems used swing axles, but modern systems use Chapman or MacPherson struts, trailing arms, multili ...

Rack And Pinion
A 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 rotational motion into 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. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear ...

Leipzig
Leipzig ( , ; Upper Saxon: ) is the most populous city in the German state of Saxony. Leipzig's population of 605,407 inhabitants (1.1 million in the larger urban zone) as of 2021 places the city as Germany's eighth most populous, as well as the second most populous city in the area of the former East Germany after (East) Berlin. Together with Halle (Saale), the city forms the polycentric Leipzig-Halle Conurbation. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about southwest of Berlin, in the southernmost part of the North German Plain (known as Leipzig Bay), at the confluence of the White Elster River (progression: ) and two of its tributaries: the Pleiße and the Parthe. The name of the city and those of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Konrad Adenauer
Konrad Hermann Joseph Adenauer (; 5 January 1876 – 19 April 1967) was a German statesman who served as the first chancellor of the Federal Republic of Germany from 1949 to 1963. From 1946 to 1966, he was the first leader of the Christian Democratic Union (CDU), a Christian-democratic party he co-founded, which became the dominant force in the country under his leadership. A devout Roman Catholic and member of the Catholic Centre Party, Adenauer was a leading politician in the Weimar Republic, serving as Mayor of Cologne (1917–1933) and as president of the Prussian State Council (1922–1933). In the early years of the Federal Republic, he switched focus from denazification to recovery, and led his country from the ruins of World War II to becoming a productive and prosperous nation that forged close relations with France, the United Kingdom and the United States. During his years in power, West Germany achieved democracy, stability, international respect and economic pros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cologne
Cologne ( ; german: Köln ; ksh, Kölle ) is the largest city of the German western state of North Rhine-Westphalia (NRW) and the fourth-most populous city of Germany with 1.1 million inhabitants in the city proper and 3.6 million people in the urban region. Centered on the left (west) bank of the Rhine, Cologne is about southeast of NRW's state capital Düsseldorf and northwest of Bonn, the former capital of West Germany. The city's medieval Catholic Cologne Cathedral (), the third-tallest church and tallest cathedral in the world, constructed to house the Shrine of the Three Kings, is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne, and Cologne is famous for Eau de Cologne, that has been produced in the city since 1709, and "cologne" has since come to be a generic term. Cologne was founded and established in Germanic Ubii ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel Laubfrosch
The Opel 4 PS, popularly known as the Laubfrosch ( treefrog), is a small two-seater car introduced by the auto maker Opel early in 1924. Subsequently, various versions of the little Laubfrosch were produced until it was replaced by the Opel 1.2 litre. Initially introduced as the Opel 4/12 PS, and manufactured at Opel's Rüsselsheim plant, this was the first German car to be assembled on a Ford inspired production line. It was aimed at the lower end of the German auto market, and clearly intended, by the standards of the day, for volume production: it sold well, with 119,484 produced by the time Laubfrosch production ended in June 1931. The name The official name referred to the fact that the car's engine size gave it a 4 tax horsepower ''(Steuer-PS)'' rating. Where a two figure name is used, as in 4/12, the second number is the claimed actual horsepower. The origins of the Laubfrosch soubriquet are not entirely clear, but may refer to the fact that Opel painted all the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanomag 2/10 PS
The Hanomag 2/10 PS is an economy car manufactured by Hanomag from 1924 until 1928. It was one of the first cars with envelope styling. It was affectionately referred to as the ''Kommissbrot'' ("Army Bread") due to its identical shape with the usual loaf of bread used by the German army at the time. "Kommiss" is German slang for "Army", short for " commissioned." The 2/10 PS (two taxable / ten brake horsepower) had a single-cylinder half litre engine behind the passengers. The rear axle was chain-driven, with no differential. With a fuel consumption of it was the world's most fuel efficient mass-production car between the two World Wars due to the low-friction one-cylinder engine and its very light weight. The fenders, or wings, of the 2/10 PS were integrated into the bodywork of the car, allowing the passenger space to be wider than it would have been with the traditional separate fenders and running board. The compact drivetrain allowed the floor to be lower, removing th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Horn
A horn is a sound-making device that can be equipped to motor vehicles, buses, bicycles, trains, trams (otherwise known as streetcars in North America), and other types of vehicles. The sound made usually resembles a "honk" (older vehicles) or a "beep" (modern vehicles). The driver uses the horn to warn others of the vehicle's approach or presence, or to call attention to some hazard. Motor vehicles, ships and trains are required by law in some countries to have horns. Like trams, trolley cars and streetcars, bicycles are also legally required to have an audible warning device in many areas, but not universally, and not always a horn. Types Bicycle Bicycles sometimes have a classic ''bulb horn'', operated by squeezing a rubber bulb attached to a metal horn. Squeezing the bulb forces air through a steel reed located in the throat of the horn, making it vibrate, producing a single note. The flaring horn matches the acoustic impedance of the reed to the open air, radiating the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
