This invention relates to a sprocket wheel used with endless tracks used to propel heavy track laying vehicles [i.e., vehicles which use endless tracks rather than tires to contact the terrain over which they are driven, e.g., tractors, tanks, bulldozers, etc.] and, more particularly, to an improved polymer sprocket wheel allowing the endless track to be driven more efficiently at highway speeds.

What is claimed is: 1. A sprocket wheel substantially made of polymer for use in cooperation with an endless elastomeric track having an outer ground-engaging surface and an inner wheel-engaging surface, said outer surface comprising tread lugs and said inner surface comprising drive lugs and guide
What is claimed is: 1. A sprocket wheel substantially made of polymer for use in cooperation with an endless elastomeric track having an outer ground-engaging surface and an inner wheel-engaging surface, said outer surface comprising tread lugs and said inner surface comprising drive lugs and guide horns, said sprocket wheel comprising a first wheel portion and a second wheel portion between which a guide horn receiving gorge is defined, said first and second wheel portions each comprises a polygonal outer track-engaging surface defining track-engaging facets, each of said track-engaging facets having a sprocket wheel pitch and comprising a support surface section substantially adjacent to said gorge and a drive lug receiving cavity for driving engagement with said drive lugs of said track, said support surface sections being substantially aligned along said outer track-engaging surface such as to define a continuous support surface. 2. A sprocket wheel as claimed in claim 1, wherein said gorge is continuous. 3. A sprocket wheel as claimed in claim 1, wherein said gorge is a shaped gorge. 4. A sprocket wheel as claimed in claim 1, wherein the shape of said drive lug receiving cavities is substantially complementary to the shape of said drive lugs. 5. A sprocket wheel as claimed in claim 1, wherein said track comprises a plurality of longitudinally extending sections, each section being attached to adjoining sections by a hinge portion, wherein each section has a track pitch which is substantially equal to said sprocket wheel pitch. 6. A sprocket wheel as claimed in claim 1, wherein said track comprises of a plurality of longitudinally extending sections, each section being attached to adjoining sections by a hinge portion, wherein each section has a track pitch which is substantially equal to 99% to 100% of said sprocket wheel pitch. 7. A sprocket wheel as claimed in claim 1, wherein said polymer is an ultra high molecular weight polyethylene. 8. A sprocket wheel as claimed in claim 1, wherein said sprocket wheel is configured for heavy tracked vehicles weighing at least 6000 kilograms. 9. A sprocket wheel as claimed in claim 1, wherein said sprocket wheel is configured for heavy tracked vehicles weighing at least 10000 kilograms. 10. A sprocket wheel as claimed in claim 1, wherein said sprocket wheel is configured for heavy tracked vehicles weighing at least 20000 kilograms. 11. A sprocket wheel substantially made of polymer for use in cooperation with an endless elastomeric track defining an outer ground-engaging surface having tread lugs thereon, and an inner wheel-engaging surface having drive lugs and guide horns thereon, said sprocket wheel comprising a first wheel portion and a second wheel portion mounted together and between which a substantially continuous guide horn receiving gorge is defined, said first and second wheel portions each comprises a polygonal outer track-engaging surface defining track-engaging facets, each of said track-engaging facets having a sprocket wheel pitch and comprising a support surface section substantially adjacent to said gorge and a drive lug receiving cavity shaped substantially complementary to said drive lugs for driving engagement therewith, said support surface sections being substantially aligned along said outer track-engaging surface such as to define a continuous support surface. 12. A sprocket wheel as claimed in claim 11, wherein said track comprises a plurality of longitudinally extending sections, each section being attached to adjoining sections by a hinge portion, wherein each section has a track pitch which is substantially equal to said sprocket wheel pitch. 13. A sprocket wheel as claimed in claim 11, wherein said track comprises of a plurality of longitudinally extending sections, each section being attached to adjoining sections by a hinge portion, wherein each section has a track pitch which is substantially equal to 99% to 100% of said sprocket wheel pitch. 14. A sprocket wheel in combination with an endless elastomeric track, said endless track defining an ground-engaging outer surface having tread lugs disposed thereon, and a wheel-engaging inner surface having drive lugs and guide horns disposed thereon, said drive lugs and said guide horns being laterally aligned and laterally spaced apart such as to define running surfaces therebetween, said track comprising a plurality of longitudinally extending track sections, each of said track section being attached to adjoining sections by a hinge portion, said sprocket wheel comprising a first wheel portion and a second wheel portion mounted together and between which a guide horn receiving gorge is defined, said first and second wheel portions each comprises a polygonal outer track-engaging surface defining track-engaging facets, each of said track-engaging facets having a sprocket wheel pitch and comprising a support surface section substantially adjacent to said gorge and a drive lug receiving cavity for engagement with said drive lugs of said track, said support surface sections being substantially aligned along said outer track-engaging surface such as to define a continuous support surface configured for engagement with said running surfaces. 15. A combination as claimed in claim 14, wherein each of said track sections has a track pitch which is substantially equal to said sprocket wheel pitch. 16. A combination as claimed in claim 14, wherein each of said track sections has a track pitch which is substantially equal to 99% to 100% of said sprocket wheel pitch.
