M32 Tank Recovery Vehicle
The M32 Armored Recovery Vehicle was an armored recovery vehicle (ARV) used during World War II and the Korean War by the United States, and was based on the chassis of the M4 Sherman medium tank. During World War II, the British also used several hundred M32s, which were obtained through Lend-Lease in 1944. The first four prototypes were produced in January 1943, labeled T5, T5E1, T5E2, T5E3, and T5E4. After a series of tests at the Aberdeen Proving Grounds, the prototypes were approved as M32, M32E1, M32E2, M32E3, and M32E4. However, the M32E4 never entered production. There were also variants that had Horizontal Volute Spring Suspension (HVSS), which were demarcated by the suffix "A1" after the model number. Lima Locomotive Works started production of the vehicles in June 1943, with five pilot vehicles (one of each model, including the M32B4 which did not enter production), 26 M32B2s, and 20 M32B3s. Pressed Steel Car produced 163 M32s and 475 M32B1s in 1944. They also produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Knox
Fort Knox is a United States Army installation in Kentucky, south of Louisville and north of Elizabethtown. It is adjacent to the United States Bullion Depository, which is used to house a large portion of the United States' official gold reserves, and with which it is often conflated. The base covers parts of Bullitt, Hardin and Meade counties. It currently holds the Army Human Resources Center of Excellence, including the Army Human Resources Command. It is named in honor of Henry Knox, Chief of Artillery in the American Revolutionary War and the first United States Secretary of War. For 60 years, Fort Knox was the home of the U.S. Army Armor Center and the U.S. Army Armor School, and was used by both the Army and the Marine Corps to train crews on the American tanks of the day; the last was the M1 Abrams main battle tank. The history of the U.S. Army's Cavalry and Armored forces, and of General George S. Patton's career, is shown at the General George Patton Museum ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Lend-Lease
Lend-Lease, formally the Lend-Lease Act and introduced as An Act to Promote the Defense of the United States (), was a policy under which the United States supplied the United Kingdom, the Soviet Union and other Allied nations with food, oil, and materiel between 1941 and 1945. It was given on the basis that such help was essential for the defense of the United States; this aid included warships and warplanes, along with other weaponry. It was signed into law on March 11, 1941, and ended on September 20, 1945. In general, the aid was free, although some hardware (such as ships) were returned after the war. Canada, already a belligerent, supplemented its aid to Great Britain with a similar, smaller program called Mutual Aid. A total of $50.1 billion (equivalent to $ in ) worth of supplies was shipped, or 17% of the total war expenditures of the U.S. In all, $31.4 billion went to the United Kingdom, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to Chin ...

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the Military history of the United States during World War II, United States and Allies of World War II, Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other Armoured_fighting_vehicle, armored fighting vehicles including self-propelled artillery, Tank_destroyer, tank destroyers, and Armoured_recovery_vehicle, armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Empire#Second World War, British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Lee, M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the 75_mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chassis
A chassis (, ; plural ''chassis'' from French châssis ) is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis. Examples of use Vehicles In the case of vehicles, the term ''rolling chassis'' means the frame plus the "running gear" like engine, transmission, drive shaft, differential and suspension. An underbody (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle. For commercial vehicles, a rolling chassis consists of an assembly of all the essential parts of a truck without the body to be ready for operation on the road. A car chassis wi ...

Armored Recovery Vehicle
An armoured recovery vehicle (ARV) is typically a powerful tank or armoured personnel carrier (APC) chassis modified for use during combat for military vehicle recovery (towing) or repair of battle-damaged, stuck, and/or inoperable armoured fighting vehicles, such as tanks and armoured personnel carriers. Most ARVs have motorized tracks, like a tank or bulldozer, enabling the ARV to operate on uneven ground. The term "Armoured Repair and Recovery Vehicle" (ARRV) is also used. ARVs may have winches, jibs, cranes, and/or bulldozer blades to aid in tank recovery. Typically, any specialized lifting and recovery equipment replaces the turret and cannon found on a battle tank. ARVs may in some cases have electric generators, blowtorches, chainsaws and fuel pumps to help with recovery operations, or spare parts, to facilitate field repairs. Some ARVs have a spade component to anchor the vehicle when it is towing or lifting. Since most ARVs are based on tank or APC chassis, they have ...

Horizontal Volute Spring Suspension
The vertical volute spring suspension system is a type of vehicle suspension system. This type of the suspension system was mainly fitted on US and Italian tanks and armored fighting vehicles starting from throughout the 1930s up until after the end of the Second World War in 1945. Development During the 1930s, many innovations in the components of light tanks would make US tanks considerably more reliable. These included rubber-bushed tracks, rear mounted radial engines and the vertical volute spring suspension. A volute spring is a compression spring in the form of a cone (a volute). Under compression the coils slide over each other, affording longer travel. The result is more stable and powerful than any leaf, coil, or torsion bar spring in the same volume. Mounted vertically in a road wheel bogie for a pair of road wheels on a tank made a very compact unit. The Rock Island Arsenal produced a small tank for the cavalry which used vertical volute spring suspension instead of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
