Flexible belt tracks for track-laying vehicles eg for climbing stairs

摘要

A flexible belt track for a tracked vehicle comprising transverse teeth 4 on its ground engaging face, the flanks of which teeth are convexly curved at least in part, or which approximate to a convex curve in part, and wherein the roots of the teeth are concavely curved. This reduces scuffing between the teeth 4 and stair treads 11, reduces loadings on the roots of the teeth and improves grip. IMAGE
