Abstract: A track link includes an elongate link body formed of a link body material that varies in hardness to form a first lower hardness zone, a second lower hardness zone, and a higher hardness zone. The higher hardness zone includes an upper rail surface of the elongate link body and extends substantially throughout the elongate link body outside of the first and second lower hardness zones, which surround the track pin bores. Related methodology for making a track link is also disclosed.

Abstract: A method of manufacturing a bicycle component having a component body formed at least partially of a fibrous composite material in a shaping mold. A shaping area of the shaping mold which serves to shape an outer section of the component body is provided with at least one intended surface roughness. At the same time, an intentional surface roughness is provided for the outer section by means of the surface roughness of the shaping area during manufacture of the outer section, to inhibit surface imperfections of the shaped outer section.

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

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

Abstract: A track joint assembly includes adjacent first and second track links each having an elongate link body with an upper rail surface located in part upon first and second link body ends and in part upon a middle section of the link. The upper rail surface forms part of a track rail having a segment formed by each of the middle sections of the elongate link bodies of the first and second track links and a compound segment formed by the two adjacent track links. The upper rail surface is formed of a sacrificial wear material that has a varying cross-sectional area structured to limit scalloping of the track links.

Abstract: The disclosure relates to a system and method for a link for a track chain in a ground-engaging track system. The link has an elongate link body including a first and a second crown. The elongate link body includes a shoe surface and a rail surface. The shoe surface is configured to contact a track shoe coupled to the elongate link body. The rail surface is opposite the shoe surface and has a first end section, a middle section, and a second end section. The first and second crowns on the rail surface each define a convex portion of the rail surface. The first crown is positioned on the first end section and the second crown is positioned on the second end section. The first and second crowns are configured to delay scallop formation in the rail surface.
