A hollow-shell road wheel for tracked vehicles includes a generally triangular, outer circumferential cavity formed by an outer rim and two wall members that extend radially inward at angles to a generally planar flange at approximately the mid-radius point of the hollow-shell road wheel. A series of hollow-shell road wheels assembled in a back-to-back configuration support the tracked-vehicle and act as guides for the track of the tracked-vehicle.

What is claimed is: 1. A hollow-shell road wheel for tracked-vehicles comprising: a peripheral rim member, said peripheral rim member including a first edge and a second edge; a flange member, said flange member including a mating surface and an exterior flange surface opposite said mating surface; a first cavity wall member, said first cavity wall member being attached to said peripheral rim member at said first edge; and a second cavity wall member, said second cavity wall member being attached to said peripheral rim member at said second edge; said first cavity wall member and said second cavity wall member being attached to said flange member; said first cavity wall member, said second cavity wall member, and said peripheral rim member defining a cavity; wherein said second cavity wall member and said flange member form a conical section, and wherein a wear ring is affixed to said first cavity wall member proximate to said first edge of said peripheral rim member, and wherein said first cavity wall member and said wear ring have a plurality of circumferentially located holes adapted to receive a plurality of fastening elements to secure said wear ring to said first cavity wall member such that said wear ring is removable and replaceable. 2. The hollow-shell road wheel of claim 1, wherein said cavity is triangular in section. 3. The hollow-shell road wheel of claim 1, wherein said first cavity wall member is angularly attached to said flange member such that said wear ring is recessed from a plane formed by said mating surface of said flange member. 4. The hollow-shell road wheel of claim 1, wherein said flange member is fixed in a plane substantially perpendicular to said peripheral rim member. 5. The hollow-shell road wheel of claim 1, wherein an elastic material is fixedly secured to said peripheral rim member. 6. The hollow-shell road wheel of claim 1, wherein said flange member has a plurality of circumferentially located mounting holes. 7. The hollow-shell road wheel of claim 1, wherein said flange member has a center hole. 8. The hollow-shell road wheel of claim 1, wherein said cavity has a plurality of circumferentially located holes adapted to allow casting core material to be removed, said holes being located in at least one of said first cavity wall member, said second cavity wall member, and said peripheral rim member. 9. The hollow-shell road wheel of claim 1 including at least one rib in said cavity for strengthening said wheel. 10. The hollow-shell road wheel of claim 1 including metallic foam within said cavity for strengthening said wheel. 11. The hollow-shell road wheel of claim 1, wherein said wheel is constructed of a material selected from the group consisting of an aluminum alloy, magnesium alloy, titanium alloy, plastic, and fiber reinforced plastic. 12. The hollow-shell road wheel of claim 1, wherein said first cavity wall member forms an angle of approximately five degrees with respect to said flange member and said second cavity wall member forms an angle of approximately forty degrees with respect to said flange member.
