Reversible Track Link System

摘要

A track assembly for a machine comprising track pads with a ground engaging surface opposite link engaging surfaces and a lug protruding between the link engaging surfaces. The track assembly includes pairs of links disposed on the link engaging surfaces of the track pads. The pairs of links include an outer link having an outer bushing end and an outer pin end, and an inner link spaced-apart from the outer link. The inner link has an inner bushing end and an inner pin end. A distance between the inner bushing ends and the outer bushing ends is less than a distance between the inner pin ends and the respective outer pin ends. The track assembly includes pins connecting the bushing ends of pairs of links to the pin ends of adjacent pairs of links forming endless chains. The endless chains connect adjacent track pads in an endless loop.

主权项

1. A track link segment for a track assembly of a mobile machine, the track link segment comprising:
a track pad having a ground engaging surface opposite first and second link engaging surfaces, and a lug protruding between the first and second link engaging surfaces and above the first and second link engaging surfaces with respect to the ground engaging surface, the lug configured to periodically engage a drive wheel of the machine; a first pair of links disposed on the first link engaging surface of the track pad, the first pair of links including:
a first outer link having an outer bushing end and an outer pin end, anda first inner link laterally and substantially symmetrically spaced apart from the first outer link, the first inner link having an inner bushing end and an inner pin end,wherein a distance between the inner bushing end of the first inner link and the outer bushing end of the first outer link is less than a distance between the inner pin end of the first inner link and the outer pin end of the first outer link; a second pair of links disposed on the second link engaging surface of the track pad, the second pair of links including:
a second outer link having an outer bushing end and an outer pin end, anda second inner link laterally and substantially symmetrically spaced apart from the second outer link, the second inner link having an inner bushing end and an inner pin end,wherein a distance between the inner bushing end of the second inner link and the outer bushing end of the second outer link is less than a distance between the inner pin end of the second inner link and the outer pin end of the second outer link; a first bushing connecting the first inner and outer links between the inner bushing end of the first inner link and the outer bushing end of the first outer link; and a second bushing connecting the second inner and outer links between the inner bushing end of the second inner link and the outer bushing end of the second outer link.
