Mercedes-Benz 130
From 1931 to 1939, Daimler-Benz AG produced three cars (Mercedes-Benz 130, 150 and 170 H) with rear engine as well as a few prototypes. Production numbers remained low for each of these models, especially compared with the production of conventional front-engine Mercedes-Benz 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 77, 87, and 97 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, working with Max Wagne ...

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 was already wind tunnel optimized at the Aerodynamics Research Institute in Göttingen and had a Automobile drag coefficient, drag coefficient of only 0.28, a value that astonished later engineers when they tested the Tropfenwagen in the 1970s. This 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 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swing Axle
A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow uneven road surfaces independently, thus enabling the vehicle's wheels to maintain better road contact and holding; plus each wheel's reduced unsprung weight means their movements have less impact on the vehicle as a whole. The first automotive application was the Rumpler Tropfenwagen, another early example was the 1923 Tatra 11 later followed by the Mercedes 130H/150H/170H, the Standard Superior, the pre-facelift Volkswagen Beetle and most of its derivatives, the Chevrolet Corvair, and the roll-over prone M151 jeep amongst others. Many later automobile rear swing axles have universal joints connecting the driveshafts to the differential, which is attached to the chassis. Swing axles do not have universal joints at the w ...

Coil Spring
A tension coil spring A coil spring is a mechanical device that typically is used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It is made of an elastic material formed into the shape of a helix that returns to its natural length when unloaded. Under tension or compression, the material (wire) of a coil spring undergoes torsion. The spring characteristics therefore depend on the shear modulus. A coil spring may also be used as a torsion spring: in this case the spring as a whole is subjected to torsion about its helical axis. The material of the spring is thereby subjected to a bending moment, either reducing or increasing the helical radius. In this mode, it is the Young's modulus of the material that determines the spring characteristics. Spring rate A selection of conical coil springs Spring rate is the measurement of how much load (in pounds) a coil spring can hold until it compresses . The spring r ...

Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Wagner (engineer)
Max Wagner (November 28, 1901 – November 16, 1975) was a Mexican-born American film actor who specialized in playing small parts such as thugs, gangsters, sailors, henchmen, bodyguards, cab drivers and moving men, appearing more than 400 films in his career, most without receiving screen credit.Erickson, HaBiography (Allmovie)/ref> In 1927, he was a leading witness in the well-publicized manslaughter trials of actor Paul Kelly and actress/screenwriter Dorothy Mackaye. Biography Wagner was one of five children, all boys, of William Wallace Wagner, a railroad conductor, and Edith Wagner, a writer who provided dispatches for the ''Christian Science Monitor'' during the Mexican Revolution. When he was 10 years old, his father was killed by rebels and the family moved to Salinas, California, where he met John Steinbeck, who became a lifelong friend. Steinbeck based the character of the boy in his novel ''The Red Pony'' on Wagner. Three of Wagner's brothers were working in Ho ...

Daimler Motoren Gesellschaft
Daimler-Motoren-Gesellschaft (abbreviated as DMG, also known as Daimler Motors Corporation) was a German engineering company and later automobile manufacturer, in operation from 1890 until 1926. Founded by Gottlieb Daimler (1834–1900) and Wilhelm Maybach (1846–1929), it was based first in Cannstatt (today Bad Cannstatt, a city district of Stuttgart). Daimler died in 1900, and their business moved in 1903 to Stuttgart-Untertürkheim after the original factory was destroyed by fire, and again to Berlin in 1922. Other factories were located in Marienfelde (near Berlin) and Sindelfingen (next to Stuttgart). The enterprise began to produce petrol engines but after the success of a small number of race cars built on contract by Wilhelm Maybach for Emil Jellinek, it began to produce the Mercedes model of 1902. After this automobile production expanded to become DMG's main product, and it built several models. Because of the post World War One German economic crisis, in 1926 DM ...

Suspension (vehicle)
Suspension is the system of tires, tire air, spring (device), springs, shock absorbers and Linkage (mechanical), linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/Automobile handling, handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. The suspension is crucial for maintaining consistent contact between the road wheel and the road surface, as all forces exerted on the vehicle by the road or ground are transmitted through the tires' contact patches. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of a manufactured object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension. The "rolling chassis" description originated from assembly production when an integrated chassis "rolled on its own tires" just before truck bodies were bolted to the frames near the end of the line. An underbody (sometimes referred to as " coachwork"), which is usually not necessary for the integrity of the structure, is built on the chassis to c ...

Cord 810
The Cord 810, and later Cord 812, was a luxury automobile produced by the Cord Automobile division of the Auburn Automobile Company in 1936 and 1937. It was the first American-designed and built front wheel drive car with independent front suspension. It was preceded by Cord's own 1929 Cord L-29, and the French 1934 Citroën Traction Avant front wheel drive cars, but the 810/812 was commercially less successful than these. The Cord 810 and 812 were also the first production cars to feature hidden/pop-up headlights. Additionally, the radical new styling of its nose completely replaced the traditional radiator grille, in favor of horizontal louvers, that curved all around the sides of the nose, earning the car's styling the nickname of 'coffin nose'. History The styling of the Cord 810 was the work of designer Gordon M. Buehrig and his team of stylists, which included young Vince Gardner and Alex Tremulis. While the first American front-wheel-drive car with independent fron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cord Automobile
Cord was a brand of American luxury automobile manufactured by the Auburn Automobile Company of Connersville, Indiana, from 1929 to 1932 and again in 1936 and 1937. Auburn was wholly owned by the Cord Corporation, founded and run by E. L. Cord as a holding company for his many transportation interests (which included the Lycoming engines, Stinson aircraft, and Checker Motors). Cord was noted for its innovative technology and streamlined designs. Innovations Cord innovations include front-wheel drive on the L-29 and hidden headlamps on the 810 and 812. Though DeSoto used them in 1942, hidden headlamps did not reappear as a luxury feature until the 1960s, beginning with the 1963 Chevrolet Corvette. It was followed two years later by another General Motors product, the Buick Riviera, whose GM stylists later stated they were trying to capture the "feel" of the Cord's design. "Servo" shifting was accomplished through a Bendix electro-vacuum pre-selector mechanism (a type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (industrialist), Louis Renault (who founded Renault, Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam engine, steam-powered devices. Applications of these devices included pumps, mill (grinding), mills and Hoist (device), hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations.
