<p>The endless traction assembly disclosed herein includes a sprocket about which an endless track is trained. The endless track has a number of flexible belts interconnected for movement in a parallel spaced relationship by a plurality of transverse traction bars secured at uniformly spaced intervals to the outer surface of the belts. Each traction bar has an offset drive section which extends into the space between the belts and is sequentially engaged by the sprocket gear teeth. The drive sections are arranged so that the line of engagement between the sprocket engaging surfaces thereof and the sprocket teeth always substantially coincides with the neutral axis of the belts.</p> |
