ABSTRACT:
Track belts designed to fit circumferentially around a pneumatic bladder or tire carcass can be sealed against the ingress of soil and rock between the track shoes attached about the outer periphery of the belt by forming individual and permanent flat sites on the outer circular periphery of the belt so the flat undersurface of each track shoe is nested on a flat shoe site and therefore does not have triangular shaped gaps under its leading and trailing edges. A transverse rib of elastomer, raised from the surface belt between each of the adjacent flat sites further seals the belt in the narrow gaps formed between adjacent track shoes thereby preventing the ingress of soil and rock in these gaps when the shoes pass through a footprint formed as the pneumatic supported system is rolled. In elevation the outer surface of this pneumatic carcass supported belt is polygonol in appearance with a ridge or rib located at each joint between adjacent flat surfaces of the shoe sites which are circumferentially disposed around the belt.
