One of the many problems with tracked vehicles is their behaviour when turning corners. A huge amount of scraping of track on ground occurs when changing direction.
Tanks, for example, when traveling on roads or fields, churn the surface up significantly -making all subsequent travel more difficult and angering local landowners.
Today’s invention attempts to lessen this by creating tracks in independent strips. Each strip is driven by its own sprocket wheel which is powered in turn by a separate differential.
This allows subtracks to move at differing rates (as shown by the shades of blue). The effect is much better grip, less surface damage and potentially greater resistance to attack (since each subtrack can be destroyed without causing immobilisation).
