TRACK JOINT ASSEMBLY AND TRACK LINK HAVING WEAR BAND STRUCTURED FOR ANTI-SCALLOPING

摘要

A track joint assembly (28) includes adjacent first and second track links (36) each having an elongate link body (42) with an upper rail surface (60) located in part upon first and second link body ends (44, 48) and in part upon a middle section (52) of the link (36). The upper rail surface (60) forms part of a track rail (34, 40) having a segment (62, 64) formed by each of the middle sections (52) of the elongate link bodies (42) of the first and second track links (36) and a compound segment (66) formed by the two adjacent track links (36). The upper rail surface (60) is formed of a sacrificial wear material that has a varying cross-sectional area structured to limit scalloping of the track links (36).
