Abstract

Un élément de suspension d'un véhicule à chenilles en particulier un bulldozer dont la durabilité et le confort sont améliorés par rapport à ceux des machines de chantier qui se déplacent sur le site de travail, est décrit. Dans un véhicule à chenille large et lourd, la durabilité d'un pivot central est faible, étant donné que la contrainte due aux chocs et aux vibrations au moment où le véhicule est en marche se concentre sur le pivot. Afin de résoudre ce problème, une traverse intermédiaire (3) est soutenue selon cette invention, par une traverse (2) montée latéralement sur des châssis principaux (1) à droite et à gauche du corps du véhicule par l'intermédiaire de tampons amortisseurs (4), et une extrémité de la barre latérale (6) est reliée à la traverse (2) alors que l'autre extrémité est reliée à la traverse (3) de manière rotative par des goupilles de l'arbre, et un équilibreur (7) dont les deux extrémités sont suspendues à partir d'un châssis est soutenu de façon à osciller librement dans une direction verticale au centre de la traverse (3) dotée d'un pivot central (8).
