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
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 track (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.

Apparatus (32) for releasably connecting a first end portion (48) to a second end portion (52) of a track assembly (12), said track assembly (12) having a plurality of pivotal joints, each joint, except one, including a pair of inner links (14), a pair of outer links (14), a bushing (16) connecting
Apparatus (32) for releasably connecting a first end portion (48) to a second end portion (52) of a track assembly (12), said track assembly (12) having a plurality of pivotal joints, each joint, except one, including a pair of inner links (14), a pair of outer links (14), a bushing (16) connecting said inner links (14), and a pin (18) extending through said bushing (16) and connecting said outer links (14), and a plurality of track shoes (20) connected to said links (14), comprising: a single discrete first coupling assembly (31) having first and second coupling members (34,36) and a first pin (38); a single discrete second coupling assembly (33) having third and fourth coupling members (40,42) and a second pin (44), said second coupling assembly (33) being spaced from said first coupling assembly (31) and from said track links (14); said first and second coupling assemblies (31,33) being substantially similar and free from connection with other coupling assemblies; means (46) for releasably joining said first and second coupling assemblies (31,33) to said track shoes (20); and, said one pivotal joint including a pair of inner links (14), a pair of outer links (14), a bushing (16) connecting said inner links (14), and being free of a connecting pin (18).
