Abstract:
1. In a continuous flexible track for extending about a plurality of aligned wheels on a vehicle or track module, the track including an outer ground-engaging surface and an inner wheel-engaging surface having inwardly-projecting wheel-engaging lugs, each lug having a proximal end, a distal surface, front and back surfaces and opposite side surfaces, the improvement comprising: the lug defining a flex-groove extending between the side surfaces and from the distal surface toward the proximal end, thereby dividing the lug into two portions to allow around-wheel hinging motion; a lug-receiving cap over and replaceably secured with respect to each lug by mechanical means including a U-shaped member having securement rod ends extending to the distal surface and securement devices engage the securement rod ends, the U-shaped member being molded into one of the portions of the lug in an orientation substantially parallel to the flex-groove; the lug-receiving cap having recessed openings accessing the U-shaped member securement rod ends; and the securement devices being at the recessed openings engaging the ends of the U-shaped member.
