Claus Luthe
Claus Luthe (December 8, 1932 – March 17, 2008) was a German car designer, noted for his design work on the NSU Ro 80, Volkswagen K70 and numerous seminal models from Audi and BMW. Luthe was a pioneer of aerodynamics and digital design within the automotive field. On his death in 2008, The Guardian called Luthe "one of the most important figures in postwar European car styling." Career Luthe was born in 1932 in Wuppertal, the second-oldest of five children in a deeply Catholic family. His father died on the Eastern Front when he was just 12 years old. Luthe originally wanted to follow his elder brother into a career in architecture, but took an apprenticeship from 1948 to 1954 as a coachbuilding student at Karosseriebauer Voll in Würzburg, where he worked on proposals for buses. After completing his apprenticeship, he joined Deutsche Fiat AG, where he was, among other activities, responsible for the frontal styling of the original 500. NSU He soon, however, joined NS ...

Wuppertal
Wuppertal (; "''Wupper Dale''") is, with a population of approximately 355,000, the seventh-largest city in North Rhine-Westphalia as well as the 17th-largest city of Germany. It was founded in 1929 by the merger of the cities and towns of Elberfeld, Barmen, Ronsdorf, Cronenberg and Vohwinkel, and was initially "Barmen-Elberfeld" before adopting its present name in 1930. It is regarded as the capital and largest city of the Bergisches Land (historically this was Düsseldorf). The city straddles the densely populated banks of the River Wupper, a tributary of the Rhine called ''Wipper'' in its upper course. Wuppertal is located between the Ruhr (Essen) to the north, Düsseldorf to the west, and Cologne to the southwest, and over time has grown together with Solingen, Remscheid and Hagen. The stretching of the city in a long band along the narrow Wupper Valley leads to a spatial impression of Wuppertal being larger than it actually is. The city is known for its steep ...

NSU Prinz 4
The NSU Prinz (Prince) is an automobile which was produced in West Germany by the NSU Motorenwerke AG from 1958 to 1973. NSU Prinz I, II & III The first post-war NSU car, the Prinz I, was launched at the Frankfurt Motor Show in September 1957 accompanied by the advertising slogan "Fahre Prinz und Du bist König" ''("Drive a Prince and you're a king")''. After a pilot run of 150 preproduction cars, volume production began in March 1958. The Prinz I was available as a 2-door saloonMichael Sedgwick & Mark Gillies, ''A-Z of Cars 1945-1970'', page 145 featuring an upright roof line and seating for four people. The doors opened wide enough to permit reasonable access even to the rear seats, although leg room was severely restricted if attempting to accommodate four full sized adults. In addition to a luggage compartment accessed via a hatch at the front of the car and shared with the spare wheel and fuel filler, there was a narrow but deep full width space behind the rear seat suffi ...

Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velocity; * ...

Disc Brakes
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Transmission
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo, while still requiring the driver to manually shift gears.

Felix Wankel
Felix Heinrich Wankel (; 13 August 1902 – 9 October 1988) was a German mechanical engineer and inventor after whom the Wankel engine was named. Early life Wankel was born in 1902 in Lahr in what was then the Grand Duchy of Baden in the Upper Rhine Plain of present-day southwestern Germany. He was the only son of Gerty Wankel (née Heidlauff) and Rudolf Wankel, a forest assessor. His father died in World War I. Thereafter, the family moved to Heidelberg. He went to high schools in Donaueschingen, Heidelberg, and Weinheim, and left school without Abitur in 1921. He learned the trade of purchaser at the Carl Winter Press in Heidelberg and worked for the publishing house until June 1926. He and some friends had already run an unofficial afterwork machine shop in a backyard shed in Heidelberg since 1924. Wankel was now determined to receive unemployment benefits and to focus on the machine shop. One of his friends, who had graduated from university, gave his name and transformed th ...

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an Eccentric (mechanism), eccentric rotary combustion engine, rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing. Due to its inherent poor thermodynamics, the Wankel engine has a significantly worse thermal efficiency and worse exhaust gas behaviour when compared against the Otto engine or the Diesel engine, which is why the Wankel engine has seen limited use since its introduction in the 1960s. However, its advantages of compact design, smoothness, lower weight and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
