Title (DE) VORRICHTUNG ZUR STEUERUNG EINER ANPRESSKRAFT EINES STROMABNEHMERS MIT EINEM RELAISVENTIL
(EN) DEVICE FOR CONTROLLING A PRESSING FORCE OF A CURRENT COLLECTOR HAVING A RELAY VALVE
(FR) DISPOSITIF DE COMMANDE D’UNE FORCE DE CONTACT D’UN COLLECTEUR DE COURANT AVEC UNE VANNE RELAIS
Abstract:
(DE) Die Erfindung betrifft eine Vorrichtung (22) zum Steuern einer benötigten Anpresskraft von einem Stromabnehmer (12) eines Fahrzeugs (10) an eine Fahrleitung (20) sowie ein Verfahren unter Verwendung einer solchen Vorrichtung (22) und ein Triebfahrzeug (10) mit mindestens einer solchen Vorrichtung (22), wobei die Vorrichtung (22) einen Vorsteuerkreis (32), einen Arbeitsdrucksteuerkreis (60) und eine Einsteilvorrichtung (50) einschließlich eines Relaisventils (40) aufweist. Der Vorsteuerkreis (32) stellt einen Vorsteuerdruck ein, und das Relaisventil (40) verwendet einem Vorsteuerdruck, um einen Leistungsdruck zu steuern um so einen benötigten Arbeitsdruck für die Anpresskraft des Stromabnehmers zur Verfügung zu stellen.
(EN) The invention relates to a device (22) for controlling a required pressing force from a current collector (12) of a vehicle (10) on an overhead line (20), a method for using such a device (22) and a power car (10) having at least one such device (22), wherein the device (22) has a pilot control circuit (32), a working pressure control circuit (60) and an adjustment device (50) including a relay valve (40). The pilot control circuit (32) adjusts a pilot control pressure and the relay valve (40) uses a pilot control pressure in order to control a power pressure in order to provide a required working pressure for the pressing force of the current collector.
(FR) L’invention concerne un dispositif (22) destiné à commander la force de contact requise d’un collecteur de courant (12) d’un véhicule (10) sur une ligne de contact (20), ainsi qu’un procédé utilisant un tel dispositif (22) et un véhicule de traction (10) équipé d’au moins un tel dispositif (22). Le dispositif (22) comprend un circuit pilote (32), un circuit de commande de pression de travail (60) et un dispositif de réglage (50) incluant une vanne de relais (40). Le circuit pilote (32) définit une pression pilote et la vanne relais (40) utilise une pression pilote pour commander une pression de puissance afin de fournir une pression de travail requise pour la force de contact du collecteur de courant.
