Harley-Davidson RL 45
The Harley-Davidson RL 45 is a model of the R-series range produced from 1932 to 1936, preceded by the DL range (1929-1931), which was Harley-Davidson's first 45 cubic-inch and first flathead V-twin motorcycle, and succeeded in 1937 by the WL. The R-series range included 45-solo, R, RL and RLD models. The RL, like the DL before it, featured a total-loss oiling system; the following WL had a recirculating oil system. Overview Despite being launched in the middle of the Great Depression, when Harley-Davidson's sales were at a twenty-year low, the RL continued in production, helping Harley-Davidson to become one of only two American motorcycle manufacturers to survive the Depression. Influenced by the way in which the automobile industry had used Art Deco stylings, Harley featured a stylized Art Deco style image on the motorcycle's fuel tank. Harley offered a competition-bred RLDR 45, and also produced a three-wheel Servi-Car (or 'Service-Car') model. Prior to the Second World W ...

Flathead Engine
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-twin Engine
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. Although widely associated with motorcycles (installed either transversely or longitudinally), V-twin engines have also been used for industrial engines and in several small cars. The V-twin design dates back to the late 1880s. Origins One of the first V-twin engines was built by Gottlieb Daimler in 1889. It was used as a stationary engine, for boats and in the Daimler Stahlradwagen ("steel-wheeled car"), Daimler's second car. The engine was also manufactured under licence in France by Panhard et Levassor. An early V-twin engined motorcycle was produced in November 1902 by the Princeps AutoCar Company in the United Kingdom. The following year, V-twin motorcycles were produced by Eclipse Motor & Cycle Co in the United Kingdom (the ''XL-ALL'' model), Glenn Curtiss in the United States, and NSU Motorenwerke in Germany. ...

Drum Brake
A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a '' clasp brake''. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a ''pinch drum brake'', though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. History The modern automobile drum brake was first used in a car made by Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative dissipated heat like the asbestos lining, though Maybach had used a less sophisticated drum brake. In the first drum brakes, levers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Band Brake
A band brake is a primary or secondary brake, consisting of a band of friction material that tightens concentrically around a cylindrical piece of equipment or EMUs to either prevent it from rotating (a static or "holding" brake), or to slow it (a dynamic brake). This application is common on winch drums and chain saws and is also used for some bicycle brakes. A former application was the locking of gear rings in epicyclic gearing. In modern automatic transmissions this task has been taken over entirely by multiple-plate clutches or multiple-plate brakes. Features Band brakes can be simple, compact, rugged, and can generate high force with a light input force. However, band brakes are prone to grabbing or chatter and loss of brake force when hot. These problems are inherent with the design and thus limit where band brakes are a good solution. Effectiveness One way to describe the effectiveness of the brake is as e^, where \mu is the coefficient of friction between ban ...

Total-loss Oiling System
A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine, and then either burned or ejected overboard. Now rare in four-stroke engines, total loss oiling is still used in many two-stroke engines. Steam engines Steam engines used many separate oil boxes, dotted around the engine. Each one was filled before starting and often refilled during running. Where access was difficult, usually because the oil box was on a moving component, the oil box had to be large enough to contain enough oil for a long working shift. To control the flow rate of oil from the reservoir to the bearing, the oil would flow through an oil wick by capillary action, rather than downwards under gravity. On steamships that ran their engines for days at a time, some crew members would be "oilers" whose primary duty was to continuously monitor and maintain oil boxes. On steam locomotives, access would be impossible during running, so in some cases centralised mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International trade fell by more than 50%, unemployment in the U.S. rose to 23% and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Art Deco
Art Deco, short for the French ''Arts Décoratifs'', and sometimes just called Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s and 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. It got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined modern styles with fine craftsmanship and rich materials. During its heyday, it represented luxury, glamour, exuberance, and faith in socia ...

Rikuo Motorcycle
was one of the first motorcycle manufacturing companies in Japan. In the early 1930s Rikuo operated under the license and name of Harley-Davidson, using their tooling, and later under the name Rikuo until 1958. Harley-Davidson themselves did not publicize this Japanese connection because the Japanese were helped in developing mass-production techniques by the introduction of this factory into Japan just prior to the Second World War. The Society of Automotive Engineers of Japan rates the 1935 Rikuoh Large Motorcycle as one of their 240 Landmarks of Japanese Automotive Technology. History The production of the Harley-Davidson in Japan resulted in large part from the United Kingdom's McKenna Tariffs modification of 1921. In 1921 the Safeguarding of Industries act placed duties of 33.3 percent on 6500 items. The tariffs were put into place to protect UK industry and levied a steep import duty against the American brands which were seen as damaging the UK motorcycle industry. ...
