A track pad is disclosed for use in a track system of a tracked machine. The track system includes a plurality of track guiding rollers having annular engagement surfaces. The track pad includes a pad body having a wear surface, and a rail surface opposite the wear surface adapted for complementary positioning with at least one track guiding roller. The rail surface includes a profile that is convex or concave. The profile is adapted to complement the at least one track guiding roller, which presents a profile that is the other of convex or concave.

1. A track pad for use in conjunction with a track system of a tracked machine including a plurality of track guiding rollers having annular engagement surfaces, the track pad comprising a pad body having a wear surface, and a rail surface opposite the wear surface, the rail surface being adapted for complementary positioning with at least one of the track guiding rollers in the track system, the rail surface including a profile that is convex or concave, said profile being adapted to complement the at least one track guiding roller presenting a profile that is the other of convex or concave, edges of the concave rail surface profile or a central section of the convex rail surface profile defining the highest portion of the rail surface profile. 2. The track pad of claim 1 wherein the profile of the rail surface is arcuate. 3. The track pad of claim 1 wherein the profile of the rail surface is generally V-shaped. 4. The track pad of claim 1 wherein the profile of the rail surface includes generally V-shaped central portion and rounded edges. 5. The track pad of claim 1 further including at least one guide flange extending from the pad body opposite the wear surface, and adapted to be disposed along at least one of the ends of the at least one track guiding roller. 6. The track pad of claim 5 including at least two guide flanges extending from the pad body opposite the wear surface, and adapted to be disposed along the ends of the at least one track guiding roller. 7. The track pad of claim 1 further including a sprocket engagement recess, the rail surface including left and right surfaces extending along either side of the sprocket engagement recess. 8. A track system for use in a tracked machine, the track system comprising: a plurality of track guiding rollers, each track guiding roller having an annular engagement surface,a track chain assembly having a plurality of track pads, at least one said track pad including a pad body having a wear surface, and a rail surface opposite the wear surface, the rail surface being adapted for complementary positioning with at least one track guiding roller in the track system, andat least one of the rail surface of the track pad and the annular engagement surface of the track guiding roller presenting an engaging surface with a convex profile while the other of the rail surface of the track pad and the annular engagement surface of the track guiding roller presents a complementary engaging surface with a concave profile, edges of the concave rail surface profile or a central section of the convex rail surface profile defining the highest portion of the rail surface profile. 9. The track system of claim 8 wherein the annular engagement surface of the track guiding roller presents the engaging surface with the convex profile, and the rail surface of the track pad presents the complementary engaging surface with the concave profile. 10. The track system of claim 8 wherein the annular engagement surface of the track guiding roller presents the engaging surface with the concave profile, and the rail surface of the track pad presents the complementary engaging surface with the convex profile. 11. The track system of claim 8 wherein the engaging surfaces are arcuate. 12. The track system of claim 8 wherein the engaging surfaces are generally V-shaped. 13. The track system of claim 8 wherein at least one of the engaging surfaces includes a generally V-shaped central portion and rounded edges. 14. The track system of claim 8 wherein the track pad further includes at least one guide flange extending from the pad body opposite the wear surface, and adapted to be disposed along at least one of the ends of the at least one track guiding roller. 15. The track system of claim 8 wherein the track pad comprises at least two guide flanges extending from the pad body opposite the wear surface, and adapted to be disposed along the ends of the at least one track guiding roller. 16. The track system of claim 8 wherein the track pad further includes a sprocket engagement recess, the rail surface including left and right surfaces extending along either side of the sprocket engagement recess. 17. A track system for use in a tracked machine, the track system comprising: a plurality of track guiding rollers, each track guiding roller having an annular engagement surface,a track chain assembly having a plurality of track pads, at least one said track pad including a pad body having a wear surface, and a rail surface opposite the wear surface, the rail surface being adapted for complementary positioning with at least one track guiding roller in the track system, andat least one of the rail surface of the track pad and the annular engagement surface of the track guiding roller presenting an engaging surface with a convex profile while the other of the rail surface of the track pad and the annular engagement surface of the track guiding roller presents a complementary engaging surface with a concave profile, the rail surface of the track pad engaging at least 25% of the width of the engagement surface of the track guiding roller, edges of the concave rail surface profile or a central section of the convex rail surface profile defining the highest portion of the rail surface profile. 18. The track system of claim 17 wherein the track pads each include a sprocket engagement recess, and the rail surface includes left and right surfaces separated by the sprocket engagement recess. 19. The track system of claim 17 wherein the rail surface of the track pad engages at least 25% and as much as 50% of the width of the engagement surface of the track guiding roller. 20. The track system of claim 17 wherein the rail surface of the track pad engages at least 50% and as much as 75% of the width of the engagement surface of the track guiding roller.
