<p>A coupling apparatus (32) releasably joins the ends of an endless track (12) of a track-type vehicle (10). The coupling apparatus (32) has first and second coupling assemblies (31,33) with each assembly having a pair of coupling members (34, 36, 40, 42) which are pivotally joined by a pin (38, 44). Each coupling assembly (31, 33) is offset laterally from the links (14) of the endless (12), and threaded fasteners (46) secure the coupling assemblies (31, 33) to shoes (20) of the endless track (12). Conventional endless track assemblies include a plurality of links, bushings, pins, and shoes, and the track is releasably joined by a master link or joint, which is also used to separate the endless track. Master links are structurally weaker than regular links, and use of such master links can result in unexpected and accelerated wear of the track. The subject coupling apparatus (32) securely joins the endless track (12) and releases the track by removing threaded fasteners which secure the first and second coupling assemblies (31, 33) to the shoes of the endless track.</p> |
