This reduces the complexity of the dual-drive system when combined with a modern engine. It also introduces a new behaviour; additional load on one track causes the other to slow as well. This is actually an improvement over the dual drive solution, as it causes the entire tank to slow, not turn towards the loaded track. [2]
The following is a (partial) listing of vehicle model numbers or M-numbers assigned by the United States Army. Some of these designations are also used by other agencies, services, and nationalities, although these various end users usually assign their own nomenclature.
A later design of cross-drive transmission, the Allison X1100, was used in the 1970s experimental US MBT-70 and XM1 [3] tanks, then later adopted in the M1 Abrams.This adopts a different principle for the steering cross-coupling: instead of a hydro-dynamic torque converter, it uses a hydrostatic combination of a hydraulic pump and a hydraulic motor.
Transfer of power to the track is accomplished by a drive wheel, or drive sprocket, driven by the motor and engaging with holes in the track links or with pegs on them to drive the track. In military vehicles, the drive wheel is typically mounted well above the contact area on the ground, allowing it to be fixed in position.
The Chevrolet Inline-4 engine was one of Chevrolet's first automobile engines, designed by Arthur Mason and introduced in 1913. Chevrolet founder Billy Durant, who previously had owned Buick which had pioneered the overhead valve engine, used the same basic engine design for Chevrolet: exposed pushrods and rocker arms which actuated valves in the detachable crossflow cylinder head.
The T55E1 3-inch gun motor carriage was a prototype vehicle developed by the Allied Machinery Manufacturing Company in 1943 for the US Army.An eight-wheel drive vehicle, the T55E1 was armed with one three-inch gun in a limited traverse mounting and a supporting .50 caliber machine gun.
On tanks and armoured vehicles, grousers are usually pads attached to the tracks; but on construction vehicles they may take the form of flat plates or bars. [ 1 ] Similar traction-improving patterns have been implemented on the surface of the wheels on tractors.
