Abstract

UN DISPOSITIF SELON L'INVENTION COMPREND UN GENERATEUR DE VALEUR DE SEUIL 8 QUI EST SENSIBLE AUX EFFORTS DE POUSSEE DE LA REMORQUE 2 SUR LE TRACTEUR 1 TRANSMIS PAR L'ATTELAGE ET EST INSTALLE ENTRE LE TRACTEUR ET LA REMORQUE, AINSI QU'UN SYSTEME LOGIQUE D'EXPLOITATION 7 POUR TRANSMETTRE DES ORDRES DE REGLAGE FONCTION DE LA GRANDEUR DE CES EFFORTS DE POUSSEE A DES ROBINETS DE COMMANDE DE PRESSION DE FREINAGE 4. LES ROBINETS 4 PEUVENT FAIRE PARTIE D'UN SYSTEME D'ANTIBLOCAGE DES ROUES, COMPRENANT EN OUTRE DES CAPTEURS 3 SUR LES ROUES, UN APPAREIL DE COMMANDE 5 SUR LE TRACTEUR 1 ET UN APPAREIL DE COMMANDE 6 SUR LA REMORQUE 2.A DEVICE ACCORDING TO THE INVENTION INCLUDES A THRESHOLD 8 GENERATOR WHICH IS SENSITIVE TO THE PUSHING EFFORTS OF THE TRAILER 2 ON THE TRACTOR 1 TRANSMITTED BY THE HITCH AND IS INSTALLED BETWEEN THE TRACTOR AND THE TRAILER, AS WELL AS A LOGIC SYSTEM OPERATION 7 TO TRANSMIT ADJUSTMENT ORDERS DEPENDING ON THE SIZE OF THESE PUSHING EFFORTS TO BRAKE PRESSURE CONTROL VALVES 4. VALVES 4 CAN BE PART OF AN ANTI-LOCK WHEEL SYSTEM, ALSO INCLUDING SENSORS 3 ON THE WHEELS, ONE CONTROL UNIT 5 ON TRACTOR 1 AND ONE CONTROL UNIT 6 ON TRAILER 2.
