Hercules DFXE
The Hercules DFXE was an American diesel truck engine produced by the Hercules Engine Company. Part of the Hercules DFX series, the DFXE is a naturally aspirated, direct injection,overhead valve, inline six-cylinder engine. The engine had a displacement of , with a bore of , a stroke of and a compression ratio of 14.8:1. It developed at 1,600 rpm and a maximum of torque at 1150 rpm; at 1600 rpm. The DFXE was designed to requirements of the British Purchasing Commission for use in the Diamond T Model 980 tank transporter. As the Diamond T Model 980 was later adopted by the US, the DFXE was one of the few diesel engines used by US tactical trucks during World War II. The engine was used in upright or horizontal configurations. It was used in the Diamond T Models 980 and 981 trucks in World War Two, the Le Tourneau Model B29 Tournapull earthmover (introduced in 1945), and the Oliver OC-18 crawler tractor (introduced in 1952),Wendel, pp 601-602. among other ...

M19 Tank Transporter
The M19 Tank Transporter ( US supply catalog designation G159) was a heavy tank transporter system used in World War II and into the 1950s. It consisted of a 12-ton 6x4 M20 Diamond T Model 980 truck and companion 12-wheel M9 trailer. Over 5,000 were produced, and employed by Allied armies throughout all theaters of war. It was superseded in the U.S. military by the M25 Tank Transporter during the war, but usefully redeployed in other tasks. It was superseded by the Thornycroft Antar in British service by the early 1950, though a few remained operational in units through 1971. History Designed as a heavy prime mover for tank transporting, the hard-cab Diamond T 980 was the product of the Diamond T Company in Chicago. In 1940 the British Purchasing Commission, looking to equip the British Army with a vehicle capable of transporting larger and heavier tanks, approached a number of American truck manufacturers to assess their models. The Diamond T Company had a long history of bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractors
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" us ...
