Reversible track link system

A track assembly for a mobile machine, the track assembly comprising:

• a plurality of track pads, each track pad comprising a ground engaging surface opposite first and second link engaging surfaces, a lug protruding between the link engaging surfaces above the link engaging surfaces with respect to the ground engaging surface, the lug configured to periodically engage a drive wheel of the machine, a first arm disposed between the first link engaging surface and the lug, and a second arm disposed between the second link engaging surface and the lug, both the first and second arms protruding above the lug with respect to the ground engaging surface;
• a plurality of first and second pairs of links, the first pairs of links disposed on the first link engaging surfaces of the track pads and the second pairs of links disposed on the second link engaging surfaces of the track pads, each of the first and second pairs of links comprising:
• an outer link having an outer bushing end and an outer pin end, and
• an inner link laterally and substantially symmetrically spaced-apart from the outer link, the inner link having an inner bushing end and an inner pin end,
• wherein a distance between the inner bushing ends of the inner links and the respective outer bushing ends of the outer links is less than a distance between the inner pin ends of the inner links and the respective outer pin ends of the outer links;
• and
• a plurality of pins connecting the inner and outer bushing ends of first pairs of links to the inner and outer pin ends of adjacent first pairs of links so as to form a first endless chain and connecting the inner and outer bushing ends of the second pairs of links to the inner and outer pin ends of the adjacent second pairs of links so as to form a second endless chain;
• wherein the first and second endless chains connect adjacent track pads in an endless loop.

A master track segment for a track assembly of a mobile machine, the master track segment comprising:

• a track pad having a ground engaging surface opposite first and second link engaging surfaces, a lug protruding between the link engaging surfaces and above the link engaging surfaces with respect to the ground engaging surface, the lug configured to periodically engage a drive wheel of the machine, a first arm disposed between the first link engaging surface and the lug, and a second arm disposed between the second link engaging surface and the lug, both the first and second arms protruding above the lug with respect to the ground engaging surface;
• a first pair of master links disposed on the first link engaging surface of the track pad, the first pair of master links including:
• a first left master link comprising a left bushing portion and a left pin portion mated to one another along a first left mating interface, and
• a first right master link comprising a right bushing portion and a right pin portion mated to one another along a first right mating interface, the first right master link being laterally spaced apart from the first left master link such that the left and right bushing portions are substantially aligned with one another and the left and right pin portions are substantially aligned with one another;
• and
• a second pair of master links disposed on the second link engaging surface of the track pad, the second pair of master links including:
• a second left master link comprising a left bushing portion mated with a left pin portion along a second left mating interface, and
• a second right master link comprising a right bushing portion and a right pin portion mated to one another along a second right mating interface, the second right master link being laterally spaced apart from the second left master link such that the left and right bushing portions are substantially aligned with one another and the left and right pin portions are substantially aligned with one another.
