Abstract

INVENTION CONCERNANT LE FREINAGE DES VEHICULES. SYSTEME DE COMMANDE DE FREINS HYDRAULIQUES ANTI-PATINAGE QUI DETECTE LA PRESENCE D'UN PATINAGE SUR UNE ROUE FREINEE ET QUI RELACHE LA PRESSION DU FREIN SUR CETTE ROUE EN EN RETIRANT DU FLUIDE. UN REGULATEUR 80 EST BRANCHE DANS UN CONDUIT D'ALIMENTATION DE FLUIDE SOUS PRESSION POUR COMMANDER L'ALLURE DE LA REAPPLICATION DES FREINS LORSQUE LE PATINAGE CESSE ET COMPREND DE PREFERENCE UN PISTON 83 EN FORME DE CUVETTE QUI PEUT SE DEPLACER DANS UN ALESAGE DE CYLINDRE 82. UN PREMIER ETRANGLEMENT 90, DE DIMENSION PREDETERMINEE, EST DEFINI DANS L'EXTREMITE DU PISTON ET UN DEUXIEME, DE DIMENSION VARIABLE, ENTRE PLUSIEURS ORIFICES RADIAUX 98 DANS LA PAROI D'ALESAGE ET UN EVIDEMENT ANNULAIRE 95 DANS LE COTE EXTERIEUR DU PISTON, COMMUNIQUANT EN PERMANENCE AVEC LE VOLUME INTERNE 88 DU PISTON. APPLICATION A LA REALISATION DE CE GENRE DE FREINS.INVENTION RELATING TO THE BRAKING OF VEHICLES. ANTI-SLIP HYDRAULIC BRAKE CONTROL SYSTEM THAT DETECTS THE PRESENCE OF SLIP ON A BRAKED WHEEL AND RELEASES THE BRAKE PRESSURE ON THAT WHEEL BY REMOVING FLUID. A REGULATOR 80 IS CONNECTED IN A PRESSURIZED FLUID SUPPLY DUCT TO CONTROL THE STATE OF THE REAPPLICATION OF THE BRAKES WHEN SKATING IS ENDED AND PREFERABLY INCLUDES A PISTON 83 IN THE FORM OF A BOWL THAT CAN MOVE IN A CYLINDER BORE 82 A FIRST STRENGTH 90, OF PREDETERMINED DIMENSION, IS DEFINED IN THE END OF THE PISTON AND A SECOND, OF VARIABLE DIMENSION, BETWEEN SEVERAL RADIAL ORIFICES 98 IN THE BALE WALL AND AN ANNULAR RECESS 95 IN THE OUTSIDE OF THE PISTON, COMMUNIQUÉ PERMANENTLY WITH THE INTERNAL VOLUME 88 OF THE PISTON. APPLICATION TO THE REALIZATION OF THIS KIND OF BRAKES.
