Title (EN) BRAKING SYSTEM OPERATED BY PRESSURE MEDIUM WITH REDUNDANT CONTROL OF THE BRAKE ACTUATORS
(FR) SYSTÈME DE FREINAGE COMMANDÉ PAR UN AGENT DE PRESSION ET DOTÉ D'UNE COMMANDE REDONDANTE DES ACTIONNEURS DE FREINAGE
(DE) DRUCKMITTELBETÄTIGTES BREMSSYSTEM MIT REDUNDANTER STEUERUNG DER BREMSAKTUATOREN
Abstract:
(EN) The invention relates to a braking system operated by pressure medium, in particular, for commercial vehicles, with at least one first brake control circuit (15a) and a second brake control circuit (15b) and at least two braking force generation devices (4, 4'), each of which being supplied with pressure medium from a brake actuator (5, 5') which comprises at least the following: a) a first connector (7, 7') for the input of control signals, b) a second connector (8, 8') for release and input of pressure medium dependent on the control signals at the first connection (7, 7'), c) a third connector (9, 9'), which is connected to the provided braking force generation device (4, 4'), wherein d) the second connector (8) of the brake actuator (5), controlled via the first connector (7) thereof by the first brake control circuit (15a), is connected to either the second connector (8') or the third connector (9') of the other brake actuator (5') for the release of pressure medium from said brake actuator (5) to the other brake actuator (5'), or from the other brake actuator (5') to said brake actuator (5) the other brake actuator being controlled by the second brake control circuit (15b) via the first connector (7') thereof.
(FR) L'invention concerne un système de freinage commandé par un agent de pression et destiné notamment à des véhicules utilitaires. Ce système de freinage comprend au moins un premier circuit de commande de freinage (15a), un deuxième circuit de commande de freinage (15b) et au moins deux dispositifs générateurs de force de freinage (4, 4') respectivement alimentés en agent de pression par un actionneur de freinage (5, 5') qui comprend au moins : a) un premier raccordement (7, 7') permettant l'injection de signaux de commande, b) un deuxième raccordement (8, 8') permettant d'extraire et d'injecter l'agent de pression en fonction des signaux de commande appliqués au niveau du premier raccordement (7, 7'), c), un troisième raccordement (9, 9') qui est en liaison avec le dispositif générateur de force de freinage (4, 4') associé, d) le deuxième raccordement (8) d'un actionneur de freinage (5) qui est commandé par le premier circuit de commande de freinage (15a) via son premier raccordement (7), est raccordé au deuxième raccordement (8') ou au troisième raccordement (9') de l'autre actionneur de freinage (5') pour dévier l'agent de pression d'un actionneur de freinage (5) vers l'autre actionneur de freinage (5') ou bien de l'autre actionneur de freinage (5') vers l'actionneur de freinage (5). L'actionneur de freinage (5') est commandé par le deuxième circuit de commande de freinage (15b) via son premier raccordement (7').
(DE) Die Erfindung betrifft ein druckmittelbetätigtes Bremssystem, insbesondere für Nutzfahrzeuge, welches mindestens einen ersten Bremssteuerkreis (15a) und einen zweiten Bremssteuerkreis (15b) umfasst sowie mindestens zwei Bremskraftzeugungseinrichtungen (4, 4'), von welchen jede von einem Bremsaktuator (5, 5') mit Druckmittel versorgt wird, der wenigstens folgendes beinhaltet: a) einen ersten Anschluss (7, 7') zum Einsteuem von Steuersignalen, b) einen zweiten Anschluss (8, 8') zum Aussteuern und zum Einsteuem von Druckmittel abhängig von den am ersten Anschluss (7, 7') anstehenden Steuersignalen, c) einen dritten Anschluss (9, 9'), welcher mit der zugeordneten Bremskrafterzeugungseinrichtung (4, 4') in Verbindung steht, wobei d) der zweite Anschluss (8) des einen Bremsaktuators (5), welcher über seine ersten Anschluss (7) vom ersten Bremssteuerkreis (15a) angesteuert wird, zum Aussteuern von Druckmittel aus dem einen Bremsaktuator (5) in den anderen Bremsaktuator (5') oder aus dem anderen Bremsaktuator (5') in den einen Bremsaktuator (5) entweder an den zweiten Anschluss (8') oder an den dritten Anschluss (9') des anderen Bremsaktuators (5') angeschlossen ist, welcher über seinen ersten Anschluss (7') vom zweiten Bremssteuerkreis (15b) angesteuert wird.
