Rumpler Tropfenwagen
The Rumpler Tropfenwagen ("Rumpler drop car", named after its raindrop shape) was a car developed by Austrian engineer Edmund Rumpler. The Tropfenwagen Aerodynamics Rumpler, born in Vienna, was known as a designer of aircraft when at the 1921 Berlin car show he introduced the Tropfenwagen. It was to be the first ''streamlined'' production car, before the Chrysler Airflow and Tatra T77. The Rumpler had a Automobile drag coefficient, drag coefficient of only 0.28, a measurement which astonished later engineers and would be competitive even today. For comparison: the top ten most aerodynamic production cars in 2014/2015 were in the range 0.26 down to 0.19. The Fiat 508, Fiat ''Balilla'' of the mid-1930s, by contrast, was rated at 0.60. To enable the car's aerodynamic shape, the Tropfenwagen also featured the world's first (single plane) curved windows. Both the windscreen and the side windows were significantly curved. Engine The car featured a Siemens, Siemens and Halske-built over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedan (automobile)
A sedan or saloon (British English) is a automobile, passenger car in a three-box styling, three-box configuration with separate compartments for an engine, passengers, and cargo. The first recorded use of the word "sedan" in reference to an automobile body occurred in 1912. The name derives from the 17th-century Litter (vehicle), litter known as a sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style include the close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan, and sedanet/sedanette. Definition A sedan () is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments. This broad definition does not differentiate sedans from various other car body styles, but in practice, the typical characteristics of sedans are: * a Pillar (car), B-pillar (between the front and rear windows) that supports the roof * two rows of seats ...

Karl Benz
Carl Friedrich Benz (; 25 November 1844 – 4 April 1929), sometimes also Karl Friedrich Benz, was a German engine designer and automotive engineer. His Benz Patent Motorcar from 1885 is considered the first practical modern automobile and first car put into series production. He received a patent for the motorcar in 1886. His company Benz & Cie., based in Mannheim, was the world's first automobile plant and largest of its day. In 1926 it merged with Daimler Motoren Gesellschaft to form Daimler-Benz which produces the Mercedes-Benz among other brands. Benz is widely regarded as "the father of the car" and "father of the automobile industry". Early life Carl Benz was born Karl Friedrich Michael Vaillant, on 25 November 1844 in Mühlburg, now a borough of Karlsruhe, Baden-Württemberg, which is part of modern Germany. His parents were Josephine Vaillant and a locomotive driver, Johann Georg Benz, whom she married a few months later. According to German law, the child acquired ...

Stout Scarab
The Stout Scarab is a streamlined 1930–1940s American car, designed by William Bushnell Stout and manufactured by Stout Engineering Laboratories and later by Stout Motor Car Company of Detroit, Michigan. The Stout Scarab is credited by some as the world's first production minivan, and a 1946 experimental prototype of the Scarab became the world's first car with a fiberglass bodyshell and air suspension. Background William B. Stout was a motorcar and aviation engineer and journalist. While he was president of the Society of Automotive Engineers, Stout met Buckminster Fuller at a major New York auto show and wrote an article on the Dymaxion Car for the society newsletter. Contemporary production cars commonly had a separate chassis and body with a long hood. The engine compartment and engine were located longitudinally behind the front axle, and ahead of the passenger compartment. The front-mounted engine typically drove the rear axle through a connecting drive shaft runn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Automobiles
A car or automobile is a motor vehicle with wheels. Most definitions of ''cars'' say that they run primarily on roads, seat one to eight people, have four wheels, and mainly transport people instead of goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex. These i ...

Mercedes-Benz 130
From 1931 to 1939, Daimler-Benz AG produced three cars (Mercedes-Benz 130, 150 and 170 H) with Rear-engine design, rear engine as well as a few prototypes. The production numbers remained quite low for each of these models, especially compared to the production of classical front-engine Mercedes cars. Development and prototypes (W17/W25D) At the beginning of the 1930s, inspired by modern streamlined shapes, there were attempts to move car engines from the forward compartment to the rear of the car. Such a move allows a reduction in the volume of the front compartment. At the same time, the voluminous rear provides a lot of space above and behind the rear axle. Moreover, when engines are rear mounted, the drive shaft is eliminated. The most famous such development was with the 1930s Tatra (car), Tatra cars under the leadership of Hans Ledwinka. In 1930, Daimler-Benz entrusted Hans Nibel with the development of a small rear-engined car, starting from the same principles. In 1931, wo ...

Metropolis (1927 Film)
''Metropolis'' is a 1927 German expressionist science-fiction drama film directed by Fritz Lang and written by Thea von Harbou in collaboration with Lang from von Harbou's 1925 novel of the same name. Intentionally written as a treatment, it stars Gustav Fröhlich, Alfred Abel, Rudolf Klein-Rogge, and Brigitte Helm. Erich Pommer produced it in the Babelsberg Studios for Universum Film A.G. (UFA). The silent film is regarded as a pioneering science-fiction movie, being among the first feature-length movies of that genre. Filming took place over 17 months in 1925–26 at a cost of more than five million Reichsmarks, or the equivalent of about € million. Made in Germany during the Weimar period, ''Metropolis'' is set in a futuristic urban dystopia and follows the attempts of Freder, the wealthy son of the city master, and Maria, a saintly figure to the workers, to overcome the vast gulf separating the classes in their city and bring the workers together with Joh Fredersen, th ...

Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...

Straight Engine
The straight or inline engine is an internal combustion engine with all cylinders aligned in one row and having no offset. Usually found in four, six and eight cylinder configurations, they have been used in automobiles, locomotives and aircraft, although the term in-line has a broader meaning when applied to aircraft engines, see Inline engine (aviation). Design A straight engine is considerably easier to build than an otherwise equivalent horizontally opposed or V engine, because both the cylinder bank and crankshaft can be milled from a single metal casting, and it requires fewer cylinder heads and camshafts. In-line engines are also smaller in overall physical dimensions than designs such as the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts. Although six-cylinder engines are inherently balanced, the four-cylinder models are inherently off balance and rough, unlike 90-degree V fours and horizontally oppos ...
