Abstract
A track-laying tractor drive track is composed of a plurality of sections which each include a link and a grouser bolted together in sandwiching relationship to a pair of side-by-side disposed flexors. The flexors each include a plurality of superposed, resilient plates encased in an elastomeric material. A lost motion connection between the plates and the link and grouser acts such that tensile loads are simultaneously carried by at least two plates both when the flexor is flat and when the flexor is bent without the plates becoming overstressed when bent. Each link includes first and second transverse bars respectively, adapted for entering adjacent receptacles formed by the teeth of a drive sprocket. A wear cap is held in place on the first transverse bar by adjacent grousers of the track while the second transverse bar includes teeth for cleaning material from the sprocket receptacles.
