Abstract

DISPOSITIF DE FREINAGE HYDRAULIQUE ASSISTE POUR ENSEMBLE TRACTEUR-REMORQUE COMPRENANT UNE POMPE 12, UNE VANNE DE DEMANDE 13, UN DISTRIBUTEUR DE FREINAGE 16 ET UN APPAREIL HYDRAULIQUE AUXILIAIRE 21, TEL QU'UNE PELLE DE CHARGEMENT. LA VANNE DE DEMANDE 13 EST AGENCEE DE FACON A S'OUVRIR SOUS L'EFFET D'UNE PRESSION PREDETERMINEE DE FLUIDE, POUR PERMETTRE A LA POMPE 12 D'ALIMENTER L'APPAREIL AUXILIAIRE 21, MAIS A SE FERMER EN REPONSE A UN SIGNAL DE PRESSION QUI LUI EST APPLIQUE PAR LE DISTRIBUTEUR DE FREINAGE 16 LORSQUE CE DERNIER EST ACTIONNE. LE SIGNAL DE PRESSION DE FLUIDE CESSE D'ETRE PRODUIT LORSQUE LES BESOINS DU DISTRIBUTEUR 16 ONT ETE SATISFAITS. LA PRESSION DE FLUIDE DU SIGNAL EST CONSTAMMENT RELIEE AU RESERVOIR DE FLUIDE 11, PAR L'INTERMEDIAIRE D'UN ETRANGLEMENT 27 POUR PERMETTRE A LA VANNE DE COMMANDE 13 DE SE ROUVRIR LORSQUE LE SIGNAL DISPARAIT. APPLICATION AUX FREINS HYDRAULIQUES DE REMORQUES DE TRACTEURS.ASSISTED HYDRAULIC BRAKING DEVICE FOR TRACTOR-TRAILER UNIT INCLUDING A PUMP 12, A DEMAND VALVE 13, A BRAKE DISTRIBUTOR 16 AND AN AUXILIARY HYDRAULIC DEVICE 21, SUCH AS A LOADING SHOVEL. DEMAND VALVE 13 IS ARRANGED TO OPEN UNDER THE EFFECT OF A PREDETERMINED FLUID PRESSURE, TO ALLOW PUMP 12 TO SUPPLY AUXILIARY DEVICE 21, BUT TO CLOSE IN RESPONSE TO A SIGNAL OF PRESSURE APPLIED TO IT BY THE BRAKE DISTRIBUTOR 16 WHEN THE LATTER IS ACTIVATED. THE FLUID PRESSURE SIGNAL CEASES TO BE GENERATED WHEN DISPENSER 16'S NEEDS HAVE BEEN MET. THE FLUID PRESSURE OF THE SIGNAL IS CONSTANTLY CONNECTED TO THE FLUID TANK 11, THROUGH A THROTTLE 27 TO ALLOW THE CONTROL VALVE 13 TO RE-OPEN WHEN THE SIGNAL DISAPPEARS. APPLICATION TO HYDRAULIC BRAKES OF TRACTOR TRAILERS.
