Title (EN) HINGE JOINT FOR TRACK LINK ASSEMBLIES
(FR) ASSEMBLAGES A CHARNIERES POUR PATINS
Abstract:
(EN) Track links have been typically difficult to service due to their size, weight, and the considerable use of press or force fits between components. According to the present invention, there is provided an easily serviceable hinge joint including two meshed hinge members having aligned bores therein. The track assembly includes two meshed track links (10, 12) one having a narrow end (20) received in a notch (22) in an enlarged end (24) in the other, aligned bores (26, 28) in the links, a hinge pin (30) received in the bore for pivoting the links together, annular grooves (40) at opposite ends of the pins, retaining rings (44) in the grooves, recesses (42) in one of the links about the bore therein adjacent the ends of the pin and defining shoulders substantially abutted by the retaining rings, and caps (50, 52) closing the recesses and having axial portions (54) about the periphery of the respective retaining rings for preventing radial movement thereof.
(FR) Les patins ont ete, d"une maniere caracteristique, difficiles a entretenir a cause de leurs dimensions, de leur poids, et des calages a la presse ou forces entre leurs composants. Selon la presente invention, un assemblage a charniere avantageux a l"entretien comprend deux elements a charniere engrenes presentant des alesages alignes. L"assemblage a chevilles comprend deux patins engrenes (10, 12), dont l"un possede une extremite etroite (20) qui est contenue dans une entaille (22) amenagee dans une extremite elargie (24) de l"autre, des alesages alignes (26, 28), une goupille de charniere (30) logee dans l"alesage pour le pivotement des assemblages, des rainures annulaires (40) aux extremites opposees des goupilles, des bagues d"arret (44) dans les rainures, des evidements (42) dans l"un des assemblages autour de l"alesage adjacents aux extremites de la goupille et definissant des epaulements sur lesquels s"appuient les bagues de retenue, et des couvercles (50, 52) fermant les evidements et ayant des parties axiales (54) autour de la peripherie des bagues d"arret respectives pour empecher leur mouvement radial.
