An improved track shoe assembly for a continuous track vehicle. The track shoe assembly comprises a pin which is rotatable relative to a shoe of the track shoe assembly. The track shoe assembly comprises an elastomeric tube through which the pin extends, the elastomeric tube being rotatable with respect to one of the pin and the shoe and being fixed with respect to the other of the pin and the shoe.

1. A track shoe assembly for a continuous track vehicle, the track shoe assembly comprising a pin and a shoe, the track shoe assembly comprising an elastomeric tube through which the pin extends, the elastomeric tube in use being rotatable with respect to one of the pin and the shoe and being fixed with respect to the other of the pin and the shoe. 2. The assembly of claim 1 wherein the track shoe assembly comprises two shoes, each shoe comprising a rigid body, an elastomeric road pad attached to one side of the body, and an elastomeric road wheel pad attached to an opposite side of the body, the rigid body having a cylindrical opening extending therethrough, and a sleeve mounted in the cylindrical opening, the elastomeric tube being mounted in the sleeve. 3. The assembly of claim 2 wherein the elastomeric tube is bonded to the interior of the sleeve and in use rotates freely with respect to the pin. 4. The assembly of any of claims 1-3 wherein the elastomeric tube is made of polyurethane having a Shore hardness of at least 65D. 5. The assembly of claim 2 wherein each sleeve is force-fit into the cylindrical opening of a shoe of the shoe assembly. 6. A method of assembling a track of a continuous track vehicle, the track comprising a plurality of track shoe assemblies, the method comprising mounting at least two coaxial elastomeric tubes to each shoe assembly, thereafter pushing pins through the coaxial elastomeric tubes, and rigidly connecting one pin associated with a first shoe assembly with a second pin associated with a second shoe assembly, the pins pushed through the elastomeric tubes rotating freely in use with respect to their respective elastomeric tubes. 7. The method of claim 6 wherein the elastomeric tube is formed of polyurethane having a Shore hardness of at least 65D. 8. The method of claim 6 comprising a step, before pushing the pin through the elastomeric tube, of machining the pin. 9. The method of claim 8 wherein the pin is machined by centerless grinding. 10. A track shoe assembly for a continuous track vehicle, the track shoe assembly comprising a pin and a shoe, the track shoe assembly comprising an elastomeric tube through which the pin extends, the elastomeric tube in use being rotatable with respect to one of the pin and the shoe and being fixed with respect to the other of the pin and the shoe, wherein the track shoe assembly comprises two shoes, each shoe comprising a rigid body, an elastomeric road pad attached to one side of the body, and an elastomeric road wheel pad attached to an opposite side of the body, the rigid body having a cylindrical opening extending therethrough, and a sleeve mounted in the cylindrical opening, the elastomeric tube being mounted in the sleeve, and wherein each rigid body has two cylindrical openings extending therethrough, and a sleeve mounted in each said cylindrical opening, each said elastomeric tube being bonded to its respective sleeve. 11. The assembly of claim 10 wherein a single said pin is rotatably mounted in two elastomeric tubes, one tube being mounted in each of said two shoes. 12. A method of assembling a track of a continuous track vehicle, the track comprising a plurality of track shoe assemblies, the method comprising mounting at least two coaxial elastomeric tubes to each shoe assembly, thereafter pushing pins through the coaxial elastomeric tubes, and rigidly connecting one pin associated with a first shoe assembly with a second pin associated with a second shoe assembly, wherein each said elastomeric tube is non-rotatably mounted in a sleeve. 13. The method of claim 12 wherein a bonding agent is applied to an inner surface of each said tube, thereafter a liquid polymer is poured into the sleeve, and thereafter the liquid polymer is cured to form the elastomeric tube. 14. The method of claim 12 further comprising forming a central bore having a diameter equal to the diameter of the pin in the elastomeric tube before the pin is pushed through the elastomeric tube. 15. A method of assembling a track shoe of a continuous track vehicle, the track shoe comprising a rigid body having two cylindrical openings extending therethrough, an elastomeric road pad attached to one side of the rigid body, and an elastomeric road wheel pad attached to an opposite side of the rigid body, the method comprising mounting a sleeve in each said cylindrical opening and bonding an elastomeric tube to each said sleeve, each elastomeric sleeve having an inner diameter, and thereafter pushing pins through the elastomeric tubes, the pins having substantially the same outer diameter as the inner diameters of the elastomeric tubes, the pins being rotatable in use with respect to the elastomeric tubes. 16. The method of claim 15 wherein the sleeves are mounted in the rigid body after at least one of the road pad and the road wheel pad is attached. 17. The method of claim 15 wherein a bonding agent is applied to an inner surface of each said sleeve, thereafter a liquid polymer is poured into the sleeve, and thereafter the liquid polymer is cured to form the elastomeric tube. 18. The method of claim 15 wherein the elastomeric tubes are bonded to the sleeves before the sleeves are mounted in the cylindrical openings of the rigid body.
