Abstract

Cette invention concerne un système de freinage en marche pour un chargeur à quatre roues motrices. Dans ce système, une extrémité de l'arbre (7) de la roue conique commandant l'essieu arrière est couplée à la roue conique (25) commandant l'essieu arrière, puis les arbres des roues de l'essieu arrière sont commandés par l'intermédiaire du différentiel arrière, l'autre l'extrémité de l'arbre est couplé à l'ensemble arbre de transmission (34), et les arbres (9) des roues de l'essieu avant sont commandés par l'ensemble arbre de transmission. Un frein hydraulique est ménagé sur l'arbre de la roue conique commandant l'essieu arrière. La structure du système décrit dans cette invention est simple et compact. L'installation du frein sur l'arbre de la roue conique commandant l'essieu arrière permet de synchroniser la rotation des différentiels avant et arrière. Lorsque le véhicule se déplace ou stationne, la force de freinage peut être appliquée aux dispositifs de commande par l'intermédiaire de l'arbre de la roue conique commandant l'essieu arrière. Ce système de freinage présente une capacité de freinage élevée, il est bon marché et il peut être entretenu de manière pratique.
