A continuous flexible track for extending about a plurality of aligned wheels on a vehicle or track module, the track includes an outer ground-engaging surface and an inner wheel-engaging surface having inwardly-projecting wheel-engaging lugs. Each lug has a proximal end, a distal surface, front and back surfaces and opposite side surfaces. Each lug further includes 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.

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; andthe securement devices being at the recessed openings engaging the ends of the U-shaped member. 2. The continuous flexible track of claim 1 wherein each lug has a height and the flex-groove extends toward the proximal end by a distance such that the depth of the flex-groove is from about 40% to about 90% of the lug height. 3. The continuous flexible track of claim 2 wherein the depth of the flex-groove is from about 50% to about 80% of the lug height. 4. The continuous flexible track of claim 1 wherein the lug-receiving cap is secured directly to one of the two lug portions. 5. The continuous flexible track of claim 1 wherein the lug-receiving cap is formed from a material comprising one of a thermoplastic elastomer, ductile metal, carbon fiber material and nanomaterial. 6. The continuous flexible track of claim 5 wherein the thermoplastic elastomer includes at least one selected from the group comprising nylon, polypropylene, polyethylene, polyamide, polyester, polycarbonate and polysulphone. 7. The continuous flexible track of claim 6 wherein the thermoplastic elastomer material includes nylon 6-6. 8. The continuous flexible track of claim 6 wherein the thermoplastic elastomer includes between about 30% and about 60% glass-reinforced nylon. 9. The continuous flexible track of claim 5 wherein the thermoplastic elastomer has a tensile strength of between about 5800 psi and about 38,000 psi. 10. A track apparatus comprising: a drive wheel engaged with a continuous flexible 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 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;a lug-receiving cap over and replaceably secured with respect to each lug by mechanical means including a U-shaped member having ends extending to the distal surface and securement devices engage the 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 ends;at least one idler wheel engaging the lugs projecting from the inner wheel-engaging surface; andthe securement devices being at the recessed openings engaging the ends of the U-shaped member, whereby, as the lugs travel about the drive wheel and the idler wheel(s), the flex-groove facilitates around-wheel hinging motion thereby increasing the life of the track. 11. The continuous flexible track of claim 10 wherein each lug has a height and the flex-groove extends toward the proximal end by a distance such that the depth of the flex-groove is from about 40% to about 90% of the lug height. 12. The continuous flexible track of claim 11 wherein the depth of the flex-groove is from about 50% to about 80% of the lug height. 13. The continuous flexible track of claim 10 wherein the lug-receiving cap is secured directly to one of the two lug portions. 14. The continuous flexible track of claim 10 wherein the lug-receiving cap is formed from a material comprising one of a thermoplastic elastomer, ductile metal, carbon fiber material and nanomaterial. 15. The continuous flexible track of claim 14 wherein the thermoplastic elastomer material includes at least one selected from the group comprising nylon, polypropylene, polyethylene, polyamide, polyester, polycarbonate and polysulphone. 16. The continuous flexible track of claim 15 wherein the thermoplastic elastomer material includes nylon 6-6. 17. The continuous flexible track of claim 15 wherein the thermoplastic elastomer includes between about 30% and about 60% glass-reinforced nylon. 18. The continuous flexible track of claim 14 wherein the thermoplastic elastomer has a tensile strength of between about 5800 psi and about 38,000 psi.
