Megola
The Megola was a German motorcycle produced between 1921 and 1925 in Munich. Like Bimota, the name is a portmanteau derived loosely from the names of its designers Meixner, Cockerell, and Landgraf. Design The Megola had a unique design, laid down by Fritz Cockerell in 1920, using a radial engine mounted within the front wheel. The engine contained five cylinders with side-mounted valves, each of which displaced , with a bore/stroke of and a total displacement of . The cylinders rotated around the front axle at six times the wheel speed; thus while the cylinders were at maximum of 3600 rpm the front wheel was turning at 600 rpm, or roughly (given the wheel diameter). A hand-controlled butterfly valve was located in the hollow crankshaft to regulate throttle. Power output was a modest but was applied directly to the wheel. This arrangement produced a very low centre of gravity and provided for excellent handling. The first prototype was built in 1920 with the five cylinders mounte ...

Fritz Cockerell
Fritz Cockerell (1889-1965) was a German pioneer of motorcycle, automotive and engine construction. Biography Fritz Cockerell (born 25 November 1889 in Munich, died 16 April 1965) was a German pioneer of motorcycle, automotive and engine construction. His real name was Friedrich Gockerell, but in his published patent documents, he is referred to as Fritz Cockerell. Fritz Cockerell initially worked as a machinist in an airship factory and later in steam turbine construction at Maffei. He then moved to Rapp Motorenwerke, which later became Bayerische Motorenwerke ( BMW), where he worked as a test engineer. Later, with Hans Meixner and Otto Landgraf, he founded the Megola works in Munich for the production of the Megola motorcycle. This was characterized by a five-cylinder rotary engine in the front wheel and around 2,000 units were built. The Megola was added to the temporary exhibition "The art of the motorcycle" by the Guggenheim Museum in 1998. Cockerell operated the and dev ...

Killinger And Freund Motorcycle
The Killinger and Freund Motorcycle was an attempt in 1935 by a group of five German engineers from Munich to design a more streamlined and modified version of the German Megola front-wheel drive motorcycle. CyberMotorcycle ''Killinger & Freund Motorcycles''(Retrieved 19 November 2006) The work took three years to complete but the result was impressive. The engine displacement stayed the same as the Megola at 600 cc but was much lighter and more simplified than a standard 100 cc of the time. Schouwer ''Killinger and Freund'' (Retrieved 19 November 2006) Design The motorcycle featured a three-cylinder two-stroke engine built right into the front wheel, transmission an ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RevoPower
The RevoPower is a motorized wheel concept, the idea being the conversion of a pedal-powered bicycle into a motorcycle. It was invented by Denver, Colorado based RevoPower Inc. The RevoPower concept is a wheel with a two-stroke engine inside it which allows the bike attached to it to travel up to at over . It is made to replace a standard bicycle wheel, and to be able to run off a standard two-stroke mixture of gasoline and oil. According to the inventor, it was designed to be a fuel efficient personal transport option for commuters, college students, and other specialty uses. History Rotary engine wheel hubs have been used in motorbikes for over one hundred years. In 1997, Steve Katsaros, the creator of the Wheel, visited a manufacturer who was experimenting with making electric powered bicycle taxis. He did not like the electric design, and began to think about how to power a bicycle with a gasoline engine, eventually deciding to keep the engine inside the wheel of the ...

Deutsches Museum
The Deutsches Museum (''German Museum'', officially (English: ''German Museum of Masterpieces of Science and Technology'')) in Munich, Germany, is the world's largest museum of science and technology, with about 28,000 exhibited objects from 50 fields of science and technology. It receives about 1.5 million visitors per year. The museum was founded on 28 June 1903, at a meeting of the Association of German Engineers (VDI) as an initiative of Oskar von Miller. It is the largest museum in Munich. For a period of time the museum was also used to host pop and rock concerts including The Who, Jimi Hendrix and Elton John. Museumsinsel The main site of the Deutsches Museum is a small island in the Isar river, which had been used for rafting wood since the Middle Ages. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher. In 1772 the Isar barracks were built on the island and, after the flooding of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonhams
Bonhams is a privately owned international auction house and one of the world's oldest and largest auctioneers of fine art and antiques. It was formed by the merger in November 2001 of Bonhams & Brooks and Phillips Son & Neale.

Solomon R
Solomon (; , ),, ; ar, سُلَيْمَان, ', , ; el, Σολομών, ; la, Salomon also called Jedidiah ( Hebrew: , Modern: , Tiberian: ''Yăḏīḏăyāh'', "beloved of Yah"), was a monarch of ancient Israel and the son and successor of David, according to the Hebrew Bible and the Old Testament. He is described as having been the penultimate ruler of an amalgamated Israel and Judah. The hypothesized dates of Solomon's reign are 970–931 BCE. After his death, his son and successor Rehoboam would adopt harsh policy towards the northern tribes, eventually leading to the splitting of the Israelites between the Kingdom of Israel in the north and the Kingdom of Judah in the south. Following the split, his patrilineal descendants ruled over Judah alone. The Bible says Solomon built the First Temple in Jerusalem, dedicating the temple to Yahweh, or God in Judaism. Solomon is portrayed as wealthy, wise and powerful, and as one of the 48 Jewish prophets. He is also th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. 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 until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
