Description
Die Erfindung betrifft ein elektrohydraulisches Ventil gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to an electrohydraulic valve according to the preamble of patent claim 1.
Aus der
Ferner sind Doppelhubmagneten bekannt, die einen Flachankermagneten zwischen zwei erregbaren Spulen aufweisen.Furthermore, Doppelhubmagneten are known which have a flat armature magnet between two excitable coils.
Aufgabe der Erfindung ist es, ein elektrohydraulisches Ventil mit erweitertem Funktionsumfang zu schaffen.The object of the invention is to provide an electro-hydraulic valve with extended functionality.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved with the features of claim 1.
Gemäß einem Vorteil ermöglicht die Verwendung eines bipolar axial magnetisierten permanentmagnetischen Ankers in Verbindung mit zwei Spulen einen aktiven bidirektionalen Betrieb des elektrohydraulischen Ventils.In one advantage, the use of a bipolar axially magnetized permanent magnet armature in conjunction with two coils enables active bidirectional operation of the electrohydraulic valve.
Diese beiden Spulen erzeugen je ein resultierendes magnetisches Feld. Jedes dieser Felder erzeugt einen axialen Kraftvektor am permanentmagnetischen Anker. Durch Stromstärke und Strompolarität werden die Größe und Richtung dieser Kräfte eingestellt. Die Spulen könne also gleichgerichtet axiale Kräfte am Anker in beide Richtungen erzeugen. Außerdem können die Spulen auch entgegengesetzte Kräfte erzeugen. Die resultierende Position des Ankers ergibt sich aus dem Kräftegleichgewicht der Summe der Magnetkräfte zu den wirkenden Federkräften.These two coils each produce a resulting magnetic field. Each of these fields generates an axial force vector at the permanent magnetic armature. Current and current polarity adjust the magnitude and direction of these forces. The coils could thus rectified generate axial forces on the armature in both directions. In addition, the coils can also generate opposing forces. The resulting position of the armature results from the equilibrium of forces of the sum of the magnetic forces to the acting spring forces.
Dieses elektromagnetische Feld übt nun entsprechend der Polarität in Abhängigkeit der resultierenden Feldstärke eine anziehende oder abstoßende Kraft auf den permanentmagnetischen Anker aus.This electromagnetic field now exerts an attractive or repelling force on the permanent magnetic armature in accordance with the polarity as a function of the resulting field strength.
In einer besonders vorteilhaften Ausgestaltung der Erfindung stützt sich der Anker – ggfs. über eine Stößelstange und/oder einen Hydraulikkolben – beidseitig an jeweils einer Schraubendruckfeder ab. Mittels dieser beiden Schraubendruckfedern lässt sich eine stromlose Mittelstellung verwirklichen. Diese Mittelstellung hat insbesondere bei 4/3-Wege-Ventilen z. B. bei der Ansteuerung von Nockenwellenverstellern üblicherweise den größten Zeitanteil über die Nutzungszeit. D. h. der Anker befindet sich bei den meisten Nutzungsarten von 4/3-Wege-Ventilen zumeist in oder nahe dieser Stellung. Durch die Stromlosigkeit dieser Stellung wird der Stromverbrauch und damit auch die Eigenerwärmung der Spule und einer diese ansteuernden Endstufe minimiert.In a particularly advantageous embodiment of the invention, the armature - if necessary. Via a push rod and / or a hydraulic piston - supported on both sides of a respective helical compression spring. By means of these two helical compression springs, an electroless middle position can be realized. This middle position has z. As in the control of camshaft adjusters usually the largest proportion of time over the period of use. Ie. The anchor is usually in or near this position for most uses of 4/3-way valves. The powerlessness of this position, the power consumption and thus the self-heating of the coil and a controlling this output stage is minimized.
Es ist jedoch auch möglich, den permanentmagnetischen Anker ohne Schraubendruckfedern im Quotientenbetrieb anzusteuern. Hierbei wirken jeweils die gegeneinander auf den Anker wirksamen Erregungen der beiden Spulen.However, it is also possible to control the permanent magnetic armature without helical compression springs in quotient mode. In each case, the mutually acting on the armature excitations of the two coils act.
Vorteilhafte Ansteuerungen des elektrohydraulischen Ventils sind in den Unteransprüchen dargestellt.Advantageous controls of the electro-hydraulic valve are shown in the subclaims.
Weitere Vorteile der Erfindung gehen aus den weiteren Patentansprüchen, der Beschreibung und der Zeichnung vor.Further advantages of the invention will become apparent from the other claims, the description and the drawings.
