Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
91 words
An endless track of the integrally molded polymeric material type for use with the slide bar suspension system of a track laying vehicle, and having a tread portion defined of an outer surface, means for receiving a drive means from an inner surface, a tensile and transverse reinforcement, and wherein the improvement comprises: an insulating material disposed in the track near and shrouding longitudinally at least part of the track inner surface, said insulating material being thermally stable at least generally 300* F. above the disintegration temperature of the polymeric material.
Claim 2
Dependent Claim
91 words
