Title (EN) UNDERCARRIAGE ASSEMBLY AND TRACK LINKS FOR ASSEMBLY
(FR) ENSEMBLE CHÂSSIS DE ROULEMENT ET MAILLONS DE CHENILLE POUR L'ENSEMBLE
Abstract:
(EN) An undercarriage assembly (116) for a mobile machine (100) includes a continuous track (120) having a plurality of mated track links (122) that can translate with respect to the machine (100). Each track link (122) may include a shoe portion (150) and a body portion (160). The body portion (160) includes a plurality of projecting pin lugs (160) each having a pin bore (168) to receive a pin and link adjacent track links (122) together. The pin lugs (160) can include a pair of sprocket lugs (190) for making rolling contact with a sprocket (142), a pair of roller lugs (200) for making rolling contact with a plurality of rollers (140), and a side lug (210) having a protruding shoulder (212) to assist in aligning the plurality of rollers (140).
(FR) L'invention concerne un ensemble châssis de roulement (116) pour une machine mobile (100), lequel ensemble comprend une chenille continue (120) comprenant une pluralité de maillons de chenille accouplés (122) qui peut effectuer une translation par rapport à la machine (100). Chaque maillon de chenille (122) peut comprendre une partie semelle (150) et une partie corps (160). La partie corps (160) comprend une pluralité d'étriers de broche (160) saillants comportant chacun un perçage d'axe (168) pour recevoir une broche et relier des maillons de chenille adjacents (122) entre eux. Les étriers de broche (160) peuvent comprendre une paire d'étriers de pignon (190) pour établir un contact de roulement avec un pignon (142), une paire d'étriers de rouleau (200) pour établir un contact de roulement avec une pluralité de rouleaux (140), et un étrier latéral (210) comportant un épaulement saillant (212) pour aider à aligner la pluralité de rouleaux (140).
