Norton Big 4
The Model 1, more commonly known as Big 4, was a Norton motorcycle made between 1907 and 1954 in various forms. With , it was the largest and most powerful side-valve engine in the model range and with plenty of low end torque was mostly used to haul sidecars. It was called Big 4 because it was rated at 4 tax horsepower. Mechanically, 'the power output, about which Norton Motors tended to be cagey, was lowly, 14 bhp for 1951'. Approximately 4700 of the nearly 100,000 military bikes made by Norton during WW2 were Big 4 sidecar outfits. Designed to carry two or three men plus their fighting equipment over very rough terrain, the Big 4 was used for reconnaissance and carrying loads of ammunition to the front line troops. Civilian Norton Big 4 The first Big 4 machines were civilian versions starting in 1907 with a bore and stroke of 82 x 120 mm. The model was produced for nine years after the end of World War II. In 1948 the stroke was reduced to 113 mm to give 596cc cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norton Motorcycle Company
The Norton Motorcycle Company (formerly Norton Motors, Ltd.) is a brand of motorcycles, originally based in Birmingham, England. For some years around 1990, the rights to use the name on motorcycles was owned by North American financiers. From 2008 to 2020, a line of motorcycles was produced under owner and chief executive Stuart Garner. Due to financial failure with large debts, in April 2020 administrators BDO agreed to sell certain aspects of Garner's business to Project 303 Bidco Limited, a new business established for the purpose with links to Indian motorcycle producer TVS Motor Company. The business was founded in 1898 as a manufacturer of "fittings and parts for the two-wheel trade".Holliday, Bob, ''Norton Story'', Patrick Stephens, 1972, p.11. By 1902 the company had begun manufacturing motorcycles with bought-in engines. In 1908 a Norton-built engine was added to the range. This began a long series of production of single and eventually twin-cylinder motorcycles, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle
A motorcycle (motorbike, bike, or trike (if three-wheeled)) is a two or three-wheeled motor vehicle steered by a handlebar. Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport (including racing), and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies. The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle. Globally, motorcycles are comparably popular to cars as a method of transport. In 2021, approximately 58.6 million new motorcycles were sold around the world, fewer than the 66.7 million cars sold over the same period. In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tax Horsepower
The tax horsepower or taxable horsepower was an early system by which taxation rates for automobiles were reckoned in some European countries such as Britain, Belgium, Germany, France and Italy; some US states like Illinois charged license plate purchase and renewal fees for passenger automobiles based on taxable horsepower. The tax horsepower rating was computed not from actual engine power but by a mathematical formula based on cylinder dimensions. At the beginning of the twentieth century, tax power was reasonably close to real power; as the internal combustion engine developed, real power became larger than nominal taxable power by a factor of ten or more. Britain The so-called RAC horsepower rating was devised in 1910 by the RAC at the invitation of the British government. The formula is: : \frac where: : D is the diameter (or bore) of the cylinder in inches, : n is the number of cylinders The formula was calculated from total piston surface area (i.e., "bore" only).

Brake Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

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] |

Friction Disc Shock Absorber
Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war. Origins The friction disk pattern was invented by Truffault, before 1900. These used oiled leather friction surfaces between bronze disks compressed by adjustable conical springs, with the disk pack floating between arms to both chassis and axle, in the distinctive style. From 1904 these were licensed to several makers including Mors, who had first applied shock absorbers to cars, and Hartford in the US. Similar dampers were also applied as steering dampers from this early date. Construction The dampers rely, as their name suggests, on the friction within a stack of disks, clamped tightly together with a spring and clamp bolt. André Hartford pattern The friction disk material was usually a wooden disk between the two faces of the steel arms. As for the development of the ...

The jeep became the primary light-wheeled multi-role vehicle of the United States military and its allies, with President Eisenhower once calling it "one of three decisive weapons the U.S. had during WWII." It was the world's first mass-produced light four-wheel drive car. With almost 650,000 units built, the jeep constituted a quarter of the total U.S. ...
