Abstract

Mécanisme de compensation destiné à protéger les chenilles d'un véhicule contre des tensions excessives. Il comprend un circuit hydraulique, comportant un cylindre dont le piston est relié à l'essieu d'une roue folle sur laquelle passe une chenille, de manière à tendre à éloigner l'essieu de cette roue de l'essieu du barbotin. Le circuit comporte des soupapes réglées de manière à permettre à l'essieu de la roue folle de se rapprocher de l'essieu du barbotin lorsque la tension de la chenille atteint une valeur limite. Une soupape permet la purge du cylindre lorsqu'il est nécessaire de procéder à des opérations d'entretien ou au démontage de la chenille. Domaine d'application : véhicules chenillés.
