Imagine a new form of tracked vehicle.
Today’s invention is a track which naturally forms a circle and which, if displaced from this shape, will attempt to spring back.
Now wrap this track around the wheels of a vehicle, as shown.
This allows it to be driven forward by the large sprocket wheels as usual, but instead of having road wheels which run at ground level, the whole system is held well above the ground and supported on the sprung tracks.
The special track could actually be made of a conventional track, inverted and shortened somewhat.
This approach provides extra suspension over very rough terrain as well as some additional protection from IEDs and mines.
