Type 87 Chi-I
The Type 87 Chi-I medium tank a/k/a Experimental tank No.1 (試製1 号戦車) was the first indigenously designed tank produced by Japan for the Imperial Japanese Army. Development of this medium tank began in June 1925 and was completed by February 1927. During the field trials, the tank proved to be too heavy and under-powered. The project was cancelled and a new light tank design was finished by April 1928 and designated the Type 89 I-Go. History Development of the first Japanese-designed tank began in June 1925. The original plan was for two types of tanks to be created. A light tank at 10-ton based on the French Renault FT tank and a 20-ton design modelled after the British Vickers tanks. A team of four engineers in the motorcar group of the Technical Bureau participated in the development of the medium tank, including a young army officer, Major Tomio Hara. Major Hara later became the head of the tank development department and would rise to the rank of general. According ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers A1E1 Independent
The Independent A1E1 is a multi-turreted tank that was designed by the British armaments manufacturer Vickers between the First and Second World Wars. Although it only ever reached the prototype stage and only a single example was built, it influenced many other tank designs. The A1E1 design can be seen as a possible influence on the Soviet T-100 and T-28 tanks, the German '' Neubaufahrzeug'' tanks, and the British Medium Mk III and Cruiser Mk I (triple turret) tank designs. The Soviet T-35 tank was heavily influenced by its design. Design The Independent was a multi-turret design, having a central gun turret armed with the 3 pounder (47 mm) gun, and four subsidiary turrets each armed with a 0.303 inch Vickers machine gun. The subsidiary turrets were mounted two at the front and two to the rear of the turret (about halfway along the hull). The gun of the left rear turret was able to elevate to engage aircraft. The tank was designed to have heavy firepower, self-defence capabi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanks Of The Interwar Period
This article discusses tanks of the interwar period. World War I established the validity of the tank concept and between the two world wars, many nations needed to have tanks, but only a few had the industrial resources to design and build them. During and after World War I, Britain and France were the intellectual leaders in tank design, with other countries generally following and adopting their designs. This early lead would be gradually lost during the course of the 1930s to the Soviet Union and, to a lesser extent, Nazi Germany. General developments The final tank designs of 1918 showed a number of trends. The joint US and British Mark VIII tank was intended to be a common heavy tank design for them and the French. The design was made to overcome the limitations of the earlier British heavy tanks. The , 37-ton armored vehicle was powered by a 300-hp (224 kW) V-12 engine and capable of 7 mph (11 km/h) cross-country. Although 100 were built, it was the ...

Tanks In The Japanese Army
This article deals with the history and development of tanks of the Japanese Army from their first use after World War I, into the interwar period, during World War II, the Cold War and modern era. Overview The First World War established the validity of the tank concept. After the war, many nations needed to have tanks, but only a few had the industrial resources to design and build them. During and after World War I, Britain and France were the intellectual leaders in tank design, with other countries generally following and adopting their designs. Japan took interest in tanks and procured some of the foreign designs, and then went to build its own. Many Japanese designs were of tankettes and light tanks, for use in campaigns in Manchuria and elsewhere in China. During the mid-1930s, the "tank actions" there were mainly against opposing infantry as the Chinese National Revolutionary Army had only three tank battalions consisting of Vickers export tanks, German PzKpfw I light ...

Imperial Japanese Army General Staff Office
The , also called the Army General Staff, was one of the two principal agencies charged with overseeing the Imperial Japanese Army. Role The was created in April 1872, along with the Navy Ministry, to replace the Ministry of Military Affairs (''Hyōbushō'') of the early Meiji government. Initially, the Army Ministry was in charge of both administration and operational command of the Imperial Japanese Army however, from December 1878, the Imperial Army General Staff Office took over all operational control of the Army, leaving the Army Ministry only with administrative functions. The Imperial Army General Staff was thus responsible for the preparation of war plans; the military training and employment of combined arms military intelligence; the direction of troop maneuvers; troop deployments; and the compilation of field service military regulations, military histories, and cartography. The Chief of the Army General Staff was the senior ranking uniformed officer in the Imper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 97 Chi-Ha
The was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, the Battles of Khalkhin Gol against the Soviet Union, and the Second World War. It was the most widely produced Japanese medium tank of World War II. The 57 mm main gun, designed for infantry support, was a carry over from the Type 89 I-Go medium tank. The suspension was derived from the Type 95 Ha-Go light tank, but used six road wheels instead of four. The 170 hp Mitsubishi air cooled diesel engine was a capable tank engine in 1938. The Type 97's low silhouette and semicircular radio antenna on the turret distinguished the tank from its contemporaries. After 1941, the tank was less effective than most Allied tank designs. In 1942, a new version of the Chi-Ha was produced with a larger three-man turret, and a high-velocity Type 1 47 mm tank gun. It was designated the Type 97-Kai or Type 97 ''Shinhōtō Chi-Ha'' ( ja, 新砲塔チハ; "New turret Chi-Ha"). History and devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 95 Ha-Go
The was a light tank used by the Empire of Japan during the Second Sino-Japanese War, at Battles of Khalkhin Gol, Nomonhan against the Soviet Union, and in the Second World War. It proved sufficient against infantry but, like the American M3 Stuart light tank, was not designed to combat other tanks. Approximately 2,300 were produced, making it the most numerous Japanese armoured fighting vehicle of the Second World War. History and development From early 1930s, the Japanese army began experimenting with a mechanized warfare unit combining infantry with tanks. However, the Type 89 I-Go, Type 89 Medium tank could not keep pace with the motorized infantry, which could move at by truck. For transport, tanks could be loaded on train platforms like in any other army of the times. To solve this problem, Tomio Hara of the Army Technical Bureau proposed a new light tank capable of 40 km/h speed and started development in 1933. The prototype of the tank was begun in 1933 and complet ... [...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] |
Bell Crank
A bellcrank is a type of crank that changes motion through an angle. The angle can be any angle from 0 to 360 degrees, but 90 degrees and 180 degrees are most common. The name comes from its first use, changing the vertical pull on a rope to a horizontal pull on the striker of a bell, used for calling staff in large houses or commercial establishments. Angles A typical 90 degree bellcrank consists of an "L" shaped crank pivoted where the two arms of the L meet. Moving rods (or cables or ropes) are attached to the ends of the L arms. When one is pulled, the L rotates around the pivot point, pulling on the other arm. A typical 180 degree bellcrank consists of a straight bar pivoted in the center. When one arm is pulled or pushed, the bar rotates around the pivot point, pulling or pushing on the other arm. Mechanical advantage Changing the length of the arms changes the mechanical advantage of the system. Many applications do not change the direction of motion but instead amplify a ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.
