Abstract: An articulated element of a track comprising two parallel faces consisting of two superimposed parts with holes for articulation bolts. The contact sides of the articulation parts have teeth which mesh with one another and move parallel to the pivoting plane. To lengthen the articulation element, the teeth move transversely and are undercut in such a way that under the effect of a tractional force they bring together the parts of the faces of the articulation elements. To facilitate the manufacture of this articulation element and to reduce its cost, the flanks (9, 10) of the teeth (5) and the toothspaces (6) are straight over the whole of their length and end freely on their longitudinal side (7 + 8). The first flanks (9) of the teeth (5) and of the toothspaces (6), which are subjected to tensile forces during rotation of the track, are set at right angles to the longitudinal direction of the track articulation, whereas the other flanks (10) of the teeth (5) and toothspaces (6), which are not subjected to tensile forces, are arranged at an acute angle in relation to one another in the longitudinal direction.

Abstract: This invention concerns a grouser pin press (10, 210) for removing a grouser pin (104) connecting grousers (102) to each other. The grouser pin press (10, 210) has driving means such as a press (20, 220) which is operable between a first, retracted configuration and a second, extended configuration. Engaging means (60, 260) is provided for engaging the grouser pin press (10, 210) with one or more grousers (102). An intermediate body (30, 230) connects the driving means (20, 220) to the engaging means (60, 260). The engaging means (60, 260) and intermediate body (30, 230) are connected to one another in a manner that allows substantially free movement between them, thereby allowing the engaging means (60, 260) and driving means (20, 220) to be aligned relative to the grouser(s) (102) independently.

Abstract: A track link is configured to be fixed to a track shoe with bolts and nuts. The track link comprises: two connecting holes which are spaced from each other by a predetermined distance in a link pitch direction and are configured to receive a link connection member respectively; a first through hole which extends orthogonal to the connecting holes and is configured to receive one of the bolts; a first surface in which the first through hole opens and on which one of the nuts is to be placed; a second through hole which extends orthogonal to the connecting hole and is configured to receive another bolt; a second surface in which the second through hole opens and on which another nut is to be placed; first projecting portions as a pair, each projecting from the first surface and facing each other in the link pitch direction across the first through hole; and second projecting portions as a pair, each projecting from the second surface and facing each other in the link pitch direction across the second through hole. The first projecting portions are spaced apart from each other by a first distance through which one of the first projecting portions engages with the nut that is to be placed between the first projecting portions but the other of the first projecting portions does not. The second projecting portions are spaced apart from each other by a second distance through which one of the second projecting portions engages with the nut that is to be placed between the second projecting portions but the other of the second projecting portions does not, or both of the second projecting portions engage with the nut.

Abstract: A track link (28) for a machine track (26) includes an elongate link body (36) having an upper rail surface (53) with an inboard peripheral edge (55) and an outboard peripheral edge (56) each formed upon a first link strap (35), a second link strap (39), and a middle section (42). The upper rail surface (53) defines a longitudinal midline (58) and at least one of the inboard peripheral edge (55) or the outboard peripheral edge (56) upon the first link strap (35) and the second link strap (39) is canted, in an inboard-outboard direction, to a longitudinal midline (58) of the upper rail surface (53).

Abstract: A track link (32) for a ground-engaging track system (16) includes an elongate link body (46) having an upper rail surface (60) located in part upon each of a first link strap (48), a second link strap (52), and a middle section (56) of the track link (32). The upper rail surface (60) is formed by a wear band (62) of sacrificial wear material having a hardness that is varied lengthwise along the upper rail surface (60) to retard scalloping of the track link (32) during service and forming relatively softer zones (64,66) in the first and second link straps (48,52) and a relatively harder zone (68) within the middle section (56). Methodology for making such a track link (32) is also disclosed.

Abstract: 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).
