Many World War II German military vehicles, initially (starting in the late 1930s) including all vehicles originally designed to be half-tracks and all later tank designs (after the Panzer IV), had slack-track systems, usually driven by a front-located drive sprocket, the track returning along the tops of a design of overlapping and sometimes ...
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.
Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both.
The first deliberate uses of bar grip tyres as off-road tyres, were developed pre-war as truck tyres particularly for army use. They used crosswise tread bars for grip, arranged in a helical pattern. [4] A helical pattern was used to avoid the uneven rolling radius and vibration of a tread with simple crosswise bars and large gaps between.
A common feature of virtually all German World War II half-tracks was the so-called Schachtellaufwerk overlapped/interleaved roadwheel arrangement with a "slack track" system possessing no return rollers under the return run of track, used from the small Kettenkrad to the nine-tonne capacity Sd.Kfz. 9 vehicle, and most famously used on Henschel ...
Churchill tanks on the Dieppe beach. The Y-shaped pipes on the rear decking are exhaust pipe extensions to allow deep wading. Although Duplex Drive allowed landing craft to release tanks farther from shore, the alternative deep wading gear permitted a tank to drive partially or completely underwater on the sea floor rather than swim.
1941 Willys T13/T14 'Super Jeep' – MB stretched to 6x6 and armed with a 37 mm gun motor carriage. Although cancelled in favor of the M6 gun motor carriage, the T14 was developed into the MT-TUG cargo/prime mover. 1941–1944 Willys MT "Super Jeep" — 6x6, 3⁄4-ton prototype — a small number were built in various configurations.
