Oshkosh TAK-4 Independent Suspension System
TAK-4 independent suspension system is a family of independent suspension systems designed and manufactured by Oshkosh Corporation for use on military, severe-duty and emergency vehicles. The system was developed from the mid-1990s. In addition to third party usage for U.S. Army and Marines Mine Resistant Ambush Protected ( MRAP) fleet upgrades, TAK-4 independent suspension system is fitted by Oshkosh to a variety of its military vehicles and by its business unit, Oshkosh Airport Products, to its Striker Aircraft Rescue Fire Fighting (ARFF) trucks and Pierce Manufacturing to its fire apparatuses. Development In 1999 Oshkosh was awarded a United States Air Force (USAF) contract to supply P23 ARFF trucks. These, and the earlier P23 supplied to the Air Force between 1994 and 1996 by Teledyne and Emergency-One (E-One) were fitted with independent suspension designed by Timoney Technology of Ireland. The success of the P23, and subsequent interest in an independent suspensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medium Tactical Vehicle Replacement
The Medium Tactical Vehicle Replacement (MTVR) is a family of medium to heavy six-wheel drive cargo and tactical trucks, used by the United States Marine Corps. The first MTVRs were delivered in late 1999. The MTVR is the equivalent of the U.S. Army's Family of Medium Tactical Vehicles (FMTV); the Marines do not use the FMTV (with the exception of the FMTV-based HIMARS) and the Army does not use the MTVR. There were originally four, later seven, MTVR variants, then nine (plus a sub-variant) as deliveries and development continued. A dedicated trailer and prototype/developmental MTVRs have also been produced. The MTVR was designed and is manufactured by Oshkosh Defense. Development and production history The MTVR has its design origins in two U.S. military programs, the 5 ton Tactical Truck Replacement (5TTR) for the U.S. Army, and the Medium Tactical Vehicle Replacement (MTVR) for the U.S. Marines. The aim of these programs was to upgrade and extend the service life of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knuckle Joint (mechanical)
The knuckles are the joints of the fingers. The word is cognate to similar words in other Germanic languages, such as the Dutch "knokkel" (knuckle) or German "Knöchel" (ankle), i.e., ''Knöchlein'', the diminutive of the German word for bone (''Knochen''). Anatomically, it is said that the knuckles consist of the metacarpophalangealUtah Mountain BikingThumb Sprain First as metacarpo. (MCP) and interphalangeal (IP) joints of the finger. The knuckles at the base of the fingers may be referred to as the 1st or major knuckles while the knuckles at the midfinger are known as the 2nd and 3rd, or minor, knuckles. However, the ordinal terms are used inconsistently and may refer to any of the knuckles. Cracking The physical mechanism behind the popping or cracking sound heard when cracking joints such as knuckles was elucidated in 2015 by cine MRI to be caused by tribonucleation as a gas bubble forms in the synovial fluid that bathes the joint. Despite this evidence, many still bel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subframe
A subframe is a structural component of a vehicle, such as an automobile or an aircraft, that uses a discrete, separate structure within a larger body-on-frame or unibody to carry specific components like the powertrain, drivetrain, and suspension. The subframe is typically bolted or welded to the vehicle. When bolted, it often includes rubber bushings or springs to dampen vibrations. The primary purposes of using a subframe are to distribute high chassis loads over a wide area of relatively thin sheet metal of a monocoque body shell and to isolate vibrations and harshness from the rest of the body. For example, in an automobile with its powertrain contained in a subframe, forces generated by the engine and transmission can be sufficiently damped to prevent disturbing the passengers. Modern vehicles use separate front and rear subframes to reduce overall weight and cost while maintaining structural integrity. Additionally, subframes benefit production by allowing subassembl ...

Double Wishbone Suspension
A double wishbone suspension is an independent suspension design for automobiles using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff ( mechanical abrasion), and more. Implementation The double-wishbone suspension can also be referred to as "double A-arms", though the arms themselves can be A-shaped or L-shaped. A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Light Tactical Vehicle
The Joint Light Tactical Vehicle (JLTV), known and marketed under Oshkosh development as the L-ATV (Light Combat Tactical All-Terrain Vehicle), is a light utility/combat multi-role vehicle. The Oshkosh-developed JLTV was selected for acquisition under the US military's Army-led Joint Light Tactical Vehicle program. In the very early stages of the program it was suggested that JLTV would replace the AM General High Mobility Multi-purpose Wheeled Vehicle (HMMWV) on a one-for-one basis. It is now suggested that the JLTV will partially replace the HMMWV. The L-ATV was designed to deliver a level of protection comparable to that of heavier and less maneuverable Mine Resistant Ambush Protected (MRAP) class designs, these having more protection from blast than up-armored HMMWVs which they were delivered to replace on deployed operations. In August 2015, the L-ATV was selected as the winner of the JLTV program. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Engine
A fire engine or fire truck (also spelled firetruck) is a vehicle, usually a specially designed or modified truck, that functions as a firefighting apparatus. The primary purposes of a fire engine include transporting firefighters and water to an incident as well as carrying equipment for firefighting operations in a fire drill. Some fire engines have specialized functions, such as wildfire suppression and aircraft rescue and firefighting, and may also carry equipment for technical rescue. Many fire engines are based on a commercial vehicle chassis that is further upgraded and customized for firefighting requirements. They are generally considered Emergency vehicle, emergency vehicles authorized to be Emergency vehicle equipment, equipped with Emergency vehicle lighting, emergency lights and Siren (alarm), sirens, as well as communication equipment such as two-way radios and mobile computer technology. The terms ''fire engine'' and ''fire truck'' are often used interchangeably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RG-33
The RG-33 is a mine-resistant light armored vehicle initially designed by BAE Systems Land Systems South Africa (formerly Land Systems OMC), a South African subsidiary of BAE Systems. BAE Systems in the US extensively modified it with additional protection, new powertrain, and suspension systems. It was built in a number of locations including York, Pennsylvania. It was one of several vehicles being fielded by the US Armed Forces in Iraq under the United States MRAP program.
