Abstract
Die Erfindung betrifft eine elektronische Druckluftversorgungseinrichtung, insbesondere für Nutzfahrzeuge, mit einem Kompressor, der über eine Förderleitung und einen Lufttrockner und ausgangsseitig des Lufttrockners über den der Arbeitsleitung abgehende Verzweigungsleitungen Durckluft in mehrere Betriebsbremskreise umfassende Druckluftverbraucherkreise einspeist, deren Drücke von Drucksensoren überwacht werden. In den Verzweigungsleitungen vor den Verbraucherkreisen sind Überströmventile angeordnet. Es ist eine Steuerelektronik vorgesehen, die die Messsignale der Drucksensoren auswertet und die Regeneration des Lufttrocknerrs, den Kompressor und Sperreinrichtungen zum Abtrennen von Verbraucherkreisen von der Druckluftversorgung steuert. Für wenigstens zwei Verbraucherkreise (18.1, 18.2) ist eine gemeinsame Sperreinrichtung (26) vorgesehen. Die gemeinsame Sperreinrichtung ist ein die Überströmventile (20.1, 20.2) der wengistens zwei Verbraucherkreise (18.1, 18.2) schaltendes, durch die Steuerelektronik (24) steuerbares, stromlos gesperrtes oder geöffnetes, elektrisch betätigbares Ventil (26), insbesondere Magnetventil.The invention relates to an electronic compressed air supply device, in particular for commercial vehicles, with a compressor which feeds via a delivery line and an air dryer and the air dryer on the output side of the working line branching branch lines Durckluft in several service brake circuits comprehensive compressed air consumer circuits whose pressures are monitored by pressure sensors. In the branch lines in front of the consumer circuits overflow valves are arranged. It is provided an electronic control system that evaluates the measurement signals of the pressure sensors and controls the regeneration of the Lufttrocknerrs, the compressor and locking devices for separating consumer circuits from the compressed air supply. For at least two consumer circuits (18.1, 18.2) a common locking device (26) is provided. The common locking device is the overflow valves (20.1, 20.2) of the wengistens two consumer circuits (18.1, 18.2) switching, by the control electronics (24) controllable, normally closed or opened, electrically actuated valve (26), in particular solenoid valve.
Description
Die Erfindung betrifft eine elektronische Druckluftversorgungseinrichtung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to an electronic compressed air supply device according to the preamble of claim 1.

Die Aufgabe der vorliegenden Erfindung besteht darin, bei einer elektronischen Druckluftversorgungsvorrichtung der eingangs genannten Art die Steuerung der Überströmventile mit geringerem Aufwand durchzuführen.The Object of the present invention is in an electronic Compressed air supply device of the type mentioned the controller to perform the relief valves with less effort.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Die Erfindung schlägt vor für zwei oder mehrere Verbraucherkreise eine gemeinsame Sperreinrichtung vorzusehen, die gemäß einer Weiterbildung vorzugsweise durch ein gemeinsames Magnetventil gebildet wird. Hierdurch werden Magnetventile eingespart und die Steuerung ist kostengünstiger und elektronisch weniger aufwendig.The Invention proposes for two or more consumer groups to provide a common locking device, which according to a Training preferably formed by a common solenoid valve becomes. As a result, solenoid valves are saved and the controller is cheaper and less expensive electronically.
Vorteilhafte und zweckmäßige Ausgestaltungen der Aufgabenlösung sind in den Unteransprüchen angegeben.advantageous and expedient embodiments of the task solution are given in the subclaims.
Die Erfindung soll nachfolgend anhand der beigefügten Zeichnung, die einen Schaltplan einer erfindungsgemäßen Druckluftversorgungsvorrichtung zeigt, näher erläutert werden.The Invention will be described below with reference to the attached drawing, a circuit diagram of a compressed air supply device according to the invention shows, will be explained in more detail.
Druckmittelleitungen sind in der Zeichnung durchgezogene Linien, elektrische Leitungen sind gestrichelte Linien.Hydraulic lines are solid lines in the drawing, electrical lines are dashed lines.
