Abstract

L'invention porte sur un système de freinage sans usure qui comporte une pompe à huile hydraulique (2) disposée sur un élément de transmission d'un véhicule, la pompe à huile hydraulique (2) étant reliée à une soupape d'huile hydraulique pneumatique (3) par l'intermédiaire d'un tube d'huile hydraulique à haute pression (8) de manière à régler la quantité de sortie d'huile de la pompe à huile hydraulique (2); une sortie d'huile de soupape d'huile (15) de la soupape d'huile hydraulique pneumatique (3) est reliée à une entrée d'un radiateur d'huile hydraulique (5) par l'intermédiaire d'un tube d'huile hydraulique à basse pression (11); une sortie du radiateur d'huile hydraulique (5) est reliée à un orifice de retour de pompe à huile (14) de pompe à huile hydraulique (2) par l'intermédiaire du tube d'huile hydraulique à basse pression (11). Le système de freinage sans usure peut assurer la sécurité de véhicules autant que possible lorsque des automobiles ou des trains descendent une longue pente, et peut réduire l'usure des pièces d'un tambour de frein, etc.
