Title (EN) CHAIN WITH MID-PITCH DRIVE AND REPLACEABLE BUSHING
(FR) CHAINE ARTICULEE AVEC TRANSMISSION A PAS MOYEN ET COUSSINET DE TRANSMISSION REMPLACABLE
Abstract: front page image
(EN)Recurring problems encountered with the use of track assemblies for track-type vehicles are preventing link walking, premature chain failure, and those problems associated with chain torques and with servicing a failed chain. The present invention comprises an improved articulated chain (10) including pivotally interconnected sections (12, 14, 16) of spaced, coacting links (18, 20, 22) having the chain driving members (54) intermediate the pivot connections (58, 60) to reduce the chain loads thereon. The links (18, 20, 22) are locked together in a common plane (56) by integral externally splined projections (82) extending therefrom into the internally splined drive bushing (96) to resist torque loads and increase the structural integrity of the chain (10). The links (18, 20, 22) are releasably coupled together to permit expeditious disassembly and reassembly thereof for servicing.
(FR)L"utilisation d"assemblages de chenilles pour des vehicules du type a chenilles se heurte periodiquement aux problemes que pose le cheminement des maillons, une defaillance prematuree de la chaine, et a ceux qui sont lies au couple de la chaine et a l"entretien d"une chaine endommagee. Une chaine articulee amelioree (10) comprend des sections interconnectees de maniere pivotante (12, 14, 16) de maillons espaces cooperants (18, 20, 22) produisant une reduction des charges de la chaine (54) intermediaires aux connexions de pivots (58, 60). Les maillons (18, 20, 22) sont verrouilles dans un plan commun (56) par des tetons integraux rainures exterieurement (82) s"etendant jusqu"au coussinet de transmission rainure interieurement (96) pour resister aux charges de couple et augmenter l"integrite structurelle de la chaine (10). Les maillons (18, 20, 22) sont couples entre eux de maniere liberable pour en permettre un demontage et un remontage rapides pour l"entretien.
