Chain links of endless treads of heavy-duty vehicles are fitted with respective track shoes each having a frustopyramidal body of elastomeric material reinforced by steel profiles, i.e. a rectangular base plate rigid with an upstanding rib embedded in the body. The rib is flanked by elongate recesses accommodating countersunk screws by which each shoe is to be secured to a respective chain link, with its base plate extending transverse to the tread over the greater part of the length of that link. Major flanks of the body, extending transversely to the treads, are inclined to the base plate at angles not exceeding 60°.

In an endless tread with hingedly interconnected chain links for the support of a heavy-duty vehicle, the combination therewith of individual track shoes respectively mounted on said chain links, each track shoe having a substantially frustopyramidal body of elastomeric material, bounded by major flanks transverse to the tread and by minor flanks paralleling the longitudinal direction of the tread, bonded onto a metallic T-profile which comprises a substantially rectangular base plate secured to the respective chain link and a rib rigid with said base plate rising from said base plate in a longitudinal direction thereof and transversely to the tread, said rib being wholly embedded in said elastomeric material and extending over a major part of said body in said longitudinal direction, at least said major flanks including a minimum angle of 30°with a perpendicular to said base plate, said base plate having longitudinal edges enveloped by said elastomeric material, said body being provided with recesses flanking said rib and accommodating countersunk mounting screws penetrating the bottoms of said recesses and said base plate, said recesses being elongated in a direction parallel to said rib, each track shoe extending transversely over the greater part of the length of the respective chain link while projecting endwise beyond the latter.
