Hercules (motorcycle)
Hercules was a brand of bicycle and motorcycle manufactured in Germany. The Hercules Company was founded in 1886 to produce bicycles by Carl Marschütz in Nuremberg, Germany and began producing motorcycles in 1904. It was merged with Zweirad Union after being purchased by ZF Sachs in 1963. In the 1950s and 1960s Sachs was the largest European fabricator of two-stroke motorcycle engines. Many of these engines were used in the ''Hercules'' line of small motorcycles, scooters and mopeds. In 1974 Hercules became the first company to offer a Wankel-engined motorcycle for sale to the general public. A prototype was first shown in 1970 at the West Cologne Autumn Motorcycle Show to a mixed reception and the production bike was sold as a Hercules product except in the United Kingdom, where it was marketed as a DKW motorcycle. The W-2000 had a single-rotor air-cooled engine of 294cc displacement that produced 23 hp, later increased to 32 hp. Cooling was by a large fan plac ...

Hercules Wankel 2000 01
Hercules (, ) is the Roman equivalent of the Greek divine hero Heracles, son of Jupiter and the mortal Alcmena. In classical mythology, Hercules is famous for his strength and for his numerous far-ranging adventures. The Romans adapted the Greek hero's iconography and myths for their literature and art under the name ''Hercules''. In later Western art and literature and in popular culture, ''Hercules'' is more commonly used than ''Heracles'' as the name of the hero. Hercules is a multifaceted figure with contradictory characteristics, which enabled later artists and writers to pick and choose how to represent him. This article provides an introduction to representations of Hercules in the later tradition. Mythology Birth and early life In Roman mythology, although Hercules was seen as the champion of the weak and a great protector, his personal problems started at birth. Juno sent two witches to prevent the birth, but they were tricked by one of Alcmene's servants and sent t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuremberg, Germany
Nuremberg ( ; german: link=no, Nürnberg ; in the local East Franconian dialect: ''Nämberch'' ) is the second-largest city of the German state of Bavaria after its capital Munich, and its 518,370 (2019) inhabitants make it the 14th-largest city in Germany. On the Pegnitz River (from its confluence with the Rednitz in Fürth onwards: Regnitz, a tributary of the River Main) and the Rhine–Main–Danube Canal, it lies in the Bavarian administrative region of Middle Franconia, and is the largest city and the unofficial capital of Franconia. Nuremberg forms with the neighbouring cities of Fürth, Erlangen and Schwabach a continuous conurbation with a total population of 800,376 (2019), which is the heart of the urban area region with around 1.4 million inhabitants, while the larger Nuremberg Metropolitan Region has approximately 3.6 million inhabitants. The city lies about north of Munich. It is the largest city in the East Franconian dialect area (colloquially: "Franconian"; ...

ZF Sachs
ZF Sachs AG, also known as Fichtel & Sachs, was founded in Schweinfurt in 1895 and was a well-known German family business. At its last point as an independent company, the company name was Fichtel & Sachs AG. In 1997, the automotive supplier was taken over by Mannesmann and renamed Mannesmann Sachs AG. As of 2001, Sachs belonged to ZF Friedrichshafen as a subsidiary company ZF Sachs AG. In 2011, ZF Sachs, like other Group subsidiaries, was legally merged with ZF Friedrichshafen AG and the independent business units integrated into the ZF divisions. Sachs has since become a brand of ZF Friedrichshafen AG. The head office for development, production and sales of products of the brand Sachs remained in Schweinfurt. The Schweinfurt plant is today (2017) the largest location of the automotive supplier ZF Friedrichshafen. Today, Fichtel & Sachs is a German manufacturer of automotive parts, producing powertrain and suspension components. In the past the company also having produced bal ...

Two-stroke Engine
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-s ...

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] |
Hercules W-2000
The Hercules W-2000 is a motorcycle which was made by Hercules in Germany. It was the first production motorcycle with a Wankel engine. It was designed in the late 1960s, first shown at a German trade show (Internationale Fahrrad und Motorrad-Ausstellung IFMA - the International Bicycle and Motorcycle show ) in 1970; the prototype had a Sachs KM-914 engine and a BMW 250 gearbox and shaft transmission; production started in 1974. Production halted in 1977 after 1,800 were built, sales were 40 units (a month) under the profit threshold. The tooling was sold to Norton Motors. Development Fichtel & Sachs, which became Hercules's parent company, was the second licensee of the Wankel engine, on Dec 29, 1960, and Sachs was the first motorcycle manufacturer with a license. Sachs had prior experience with Wankel applications in personal watercraft and power tools. The 1970 Hercules motorcycle prototype had shaft drive. It may be on display in the Motorcycle Museum which is part of the Zen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lubrication
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic or hydrostatic pressure, which reduces solid body interactions (and consequently friction and wear). Depending on the degree of surface separation, different lubrication regimes can be distinguished. Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings. When lubrication breaks down, components can rub destructively against each other, causing heat, local welding, destructive damage and failure. Lubrication mechanisms Fluid-lubricated systems As the load increases on the contacting surfaces, distinct situations can be observed wi ...

Birmingham Small Arms
The Birmingham Small Arms Company Limited (BSA) was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand, power, and machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. After the Second World War, BSA did not manage its business well, and a government-organised rescue operation in 1973 led to a takeover of such operations as it still owned. Those few that survived this process disappeared into the ownership of other businesses. History of the BSA industrial group Machine-made guns BSA began in June 1861 in the Gun Quarter, Birmingham, England. It was formed by a group of fourteen gunsmith members of the Birmingham Small Arms Trade Association specifically to manufacture guns by machinery. They were encouraged to do this by the War Office which gave the BSA gunsmiths free access to technical drawings and to the War ...

David Garside
David W. Garside is an inventor and former project engineer at BSA's Umberslade Hall research facility. He is notable for having developed an air-cooled twin-rotor Wankel motorcycle engine which powered the Norton Classic road bike. Although the Classic was not the first production rotary-engined bike, it was significantly lighter, smoother, more powerful and better-handling than the contemporary Suzuki RE5. Personal history In his book "Norton Rotaries", Kris Perkins states that "David Garside could rightly be called the father of the Norton Rotary". Garside studied mathematics and mechanical engineering at Emmanuel College, Cambridge, where he obtained a first class degree. He served an apprenticeship with Rolls-Royce, and after a spell at the CEGB, he returned to Rolls-Royce to work on diesel rotaries. He later moved to BSA as a development engineer at Kitts Green. After BSA was subsumed into NVT, over 90% of BSA's research projects were cancelled, but Garside managed to per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Classic
The Norton Classic is a rotary-engined motorcycle built in 1987 by Norton as a special edition of just 100 machines. Engine development The Classic used an air-cooled twin-rotor Wankel engine that had been developed by David Garside at BSA's Umberslade Hall research facility. Garside, who had been impressed by the air-cooled single-rotor Fichtel & Sachs engine in the Hercules motorcycle, installed a bought-in F&S engine into a BSA B25 'Starfire' frame as a "proof of concept". This proved reliable and smooth, but under-powered. Having obtained a licence from Felix Wankel in 1972, Garside then created a prototype twin-rotor engine (with F&S rotors) which doubled the capacity of the earlier test "mule". This twin-rotor engine was installed in a BSA A65 frame. Wankel engines run very hot, so in addition to its very deep cooling fins Garside gave this air-cooled motor interior air-cooling. Air was drawn through a forward-facing filter situated to provide a ram air effect. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
