Description

Schwinqunqs- und pulsationsqedämpfter eiektropπeumatischer Wandler Schwinqunqs- and Pulsationsqedämpfter eiektropπeumatischer converter
Die Erfindung betrifft einen elektropneumatischen Wandler, der beispielsweise zur pneumatischen Steuerung in Kraftfahrzeugen eingesetzt wird, indem aus dem Ansaugdruck einer Brennkraftmaschine und dem atmosphärischen Druck ein Mischdruck gebildet wird, der einem Verbraucher, beispielsweise einem Abgasrύckfύhrungsventil, zugeführt wird.The invention relates to an electropneumatic converter, which is used for example for pneumatic control in motor vehicles by a mixing pressure is formed from the intake pressure of an internal combustion engine and the atmospheric pressure, which is a consumer, for example, a Abgasrύckfύhrungsventil supplied.
Ein derartiger Wandler ist beispielsweise in DE 41 10 003 Cl beschrieben. Dieser weist drei Anschlüsse auf, wobei der erste Anschluss mit einem Unterdruck und der zweite Anschiuss mit Atmosphärendruck und der dritte Anschluss mit einem Mischdruck des ersten und des zweiten Anschlusses beaufschlagt ist, der einem Verbraucher, beispielsweise einem Abgasruckführungsventil zugeführt wird. Ferner weist dieser Wandler eine Ventileinrichtung sowie einen fest mit dieser verbundenen Tauchanker auf, der durch einen Elektromagneten verschiebbar ist, so dass die Stellung der Ventileinrichtung verändert werden und der dem Verbraucher zugeführte Mischdruck geregelt werden kann. Die Ventileinrichtung sowie der mit ihr verbundene Anker sind in axialer Richtung beweglich an einer Membran aufgehängt.Such a converter is described for example in DE 41 10 003 Cl. This has three ports, wherein the first port is subjected to a negative pressure and the second Anschiuss to atmospheric pressure and the third port with a mixing pressure of the first and the second terminal, which is supplied to a consumer, for example, an exhaust gas recirculation valve. Further, this converter has a valve device and a fixedly connected thereto plunger armature, which is displaceable by an electromagnet, so that the position of the valve device can be changed and the consumer supplied mixing pressure can be controlled. The valve device and the anchor connected to it are suspended in the axial direction movable on a membrane.
Nachteilig an einem solchen Druckwandler ist, dass der Anker und die Ventileinrichtung in axialer Richtung frei schwingen können, wobei unerwünschte Schwingungen insbesondere durch Motorvibrationen oder durch Druckpulsationen seitens der angeschlossenen Komponenten hervorgerufen werden können. Besonders häufig tritt dieser unerwünschte Effekt in Verbindung mit Unterdruckpulsationen auf.A disadvantage of such a pressure transducer is that the armature and the valve device can oscillate freely in the axial direction, with undesirable vibrations being caused in particular by engine vibrations or by pressure pulsations on the part of the connected components can be. This undesirable effect occurs in conjunction with negative pressure pulsations.
Weiterhin können Pulsationen in einem Zustand auftreten, in dem der Elektromagnet nicht von einem Strom durchflössen ist und damit keine Kraft auf den Tauchanker und die Ventiieinrichtung übertragen kann. Unerwünschte Schwingungen des Tauchankers und der Ventileinrichtung führen zu Störungen beim Betrieb der Brennkraftmaschine.Furthermore, pulsations can occur in a state in which the electromagnet is not flowed through by a current and thus can not transmit any force to the plunger rod and the valve device. Unwanted vibrations of the plunger armature and the valve device lead to disturbances in the operation of the internal combustion engine.
Aufgabe der Erfindung ist es, einen eiektropneumatischen Druckwandler zu schaffen, der einen verbesserten, störungsfreieren Betrieb der Brennkraftmaschine ermöglicht.The object of the invention is to provide a eiektropneumatischen pressure transducer, which allows improved, trouble-free operation of the internal combustion engine.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale des Anspruchs 1.The object is achieved according to the invention by the features of claim 1.
Zur Dämpfung der axialen Bewegung des Ankers und der mit ihm verbundenen Ventileinrichtung ist ein Dämpfungselement vorgesehen. Dadurch werden unerwünschte Schwingungen des Ankers und der mit ihm verbundenen Ventiieinrichtung in axialer Richtung wirksam vermieden, so dass ein störungsfreierer Betrieb der Brennkraftmaschine möglich ist.For damping the axial movement of the armature and the valve device connected to it, a damping element is provided. As a result, unwanted vibrations of the armature and associated with him Ventiieinrichtung be effectively avoided in the axial direction, so that a trouble-free operation of the internal combustion engine is possible.
Insbesondere wird durch die Erfindung eine Verringerung von Pulsationen im stromlosen Zustand sowie im Betriebsbereich des efektropneumatischen Wandlers ermöglicht. Weiterhin führt die Erfindung zu einem besseren Groß- und Kleinsignalverhalten des eiektropneumatischen Wandlers beim Belüftungsvorgang.In particular, the invention allows a reduction of pulsations in the de-energized state and in the operating range of the efektropneumatischen converter. Furthermore, the invention leads to a better large and small signal behavior of eiektropneumatischen converter in the ventilation process.
Das Dämpfungselement kann insbesondere zwischen der Ventiieinrichtung und einem Gehäuse angeordnet sein. Auch kann das Dämpfungselement zwischen dem Anker und einem unter dem Anker befindlichen Eisenkern angeordnet sein. In einer bevorzugten Ausfuhrungsform weist das Dämpfungselement ein Elastomer auf und kann insbesondere aus Elastomer ausgebildet sein.The damping element may in particular be arranged between the valve device and a housing. Also, the damping element between the armature and an iron core located under the armature can be arranged. In a preferred embodiment, the damping element comprises an elastomer and may be formed in particular from elastomer.
Weiterhin kann das Dämpfungselement beispielsweise als Membran oder als Feder ausgebildet sein.Furthermore, the damping element may be formed, for example, as a membrane or as a spring.
In einer weiteren bevorzugten Ausführungsform weist das Dämpfungseiement einen Schaumstoff, insbesondere Polyurethan, auf oder ist insbesondere aus diesem ausgebildet.In a further preferred embodiment, the damping element has a foam, in particular polyurethane, or is in particular formed from this.
Unabhängig vom verwendeten Material kann das Dämpfungselement, wie oben beschrieben, an verschiedenen Stellen des elektropneumatischen Wandlers angebracht sein, so dass eine Dämpfung der axialen Bewegung des Ankers und der mit ihm verbundenen Ventileinrichtung ermöglicht wird.Regardless of the material used, the damping element, as described above, be mounted at different locations of the electropneumatic transducer, so that a damping of the axial movement of the armature and the valve device connected to it is made possible.
Besonders bevorzugt ist es, das Dämpfungselement in die Aufhängevorrichtung zu integrieren, durch die der Ventilkörper und der mit ihm verbundene Anker in axialer Richtung beweglich aufgehängt sind. Beispielsweise kann das Dämpfungselement durch in der Aufhängevorrichtung integrierte Dämpfungsbeinchen realisiert werden, wodurch die Montage eines zusätzlichen Dämpfungselements entfällt. Weiterhin kann das Dämpfungselement in andere vorhandene Bauteile des elektropneumatischen Wandlers integriert werden, d.h, diese Bauteile können neben ihrer eigentlichen Funktion auch eine Dämpfungsfunktion bzgl. der axialen Bewegung des Ankers und der mit ihm verbundenen Ventileinrichtung erfüllen. Der Einsatz eines zusätzlichen Dämpfungselementes ist in einer solchen Anordnung nicht notwendig. Der Begriff integriert bedeutet in diesem Zusammenhang, dass das weitere Bauteil und das DämpfungseSement einstuckig ausgebildet sind, wobei das Dämpfungselement und das weitere Bauteil zwei Komponenten sind, die fest miteinander verbunden sind oder es sich bei dem Dämpfungselement und dem weiteren Bauteil um eine einzige Komponente handelt, die monolithisch ausgebildet ist,It is particularly preferred to integrate the damping element in the suspension device, through which the valve body and the armature connected to it are suspended in the axial direction movable. For example, the damping element can be realized by integrated in the suspension damping legs, whereby the installation of an additional damping element is eliminated. Furthermore, the damping element can be integrated into other existing components of the electropneumatic converter, ie, these components can fulfill not only their actual function but also a damping function with respect to the axial movement of the armature and the valve device connected to it. The use of an additional damping element is not necessary in such an arrangement. The term integrated means in this context that the further component and the DämpfungseSement are formed einstuckig, wherein the damping element and the further component are two components which are fixedly connected to each other or it the damping element and the further component are a single component which is monolithic,
Besonders bevorzugt ist eine Anordnung des Dämpfungselements an der mit dem Atmosphärendruck beaufschlagten Beluftungsseite des eiektropneumatischen Wandlers. Dadurch kann der Schließvorgang der Ventileinrichtung kurz verzögert werden, wodurch das Verhalten des eiektropneumatischen Wandlers insbesondere im Kleinsignalbereich verbessert wird, Dabei verschließt die Ventilplatte des Faltenbalgs das Unterdruckrohr, das insbesondere als Messingrohr ausgebildet sein kann, und die Belüftung findet am Faltenbalg vorbei statt. Die durch das Dämpfungselement eingeleitete Kraft auf den Anker bewirkt, dass der im Anker integrierte zweite Ventilsitz verzögert geschlossen wird. Durch die Dichtfläche des Faltenbalgs wird der Unterdruckanschluss (Unterdruckquelle/ Pumpe) möglichst lange geschlossen gehalten, um eine Belüftung zu ermöglichen. Eine derartige Anordnung bewirkt insbesondere ein verbessertes Groß- und Kleinsignalverhalten beim Belüftungsvorgang, Der Anschluss zur Atmosphäre soll dabei möglichst lange geöffnet bleiben. Dadurch kann beispielsweise ein Unterdruck schneller abgebaut werden. Wenn der Wirkdruck und die Kraft, die durch den Elektromagneten auf den Anker übertragen wird, annähernd im Gleichgewicht sind, schließt die Ventilebene des Faltenbalgs beide Ventilsitze, Die weitere Belüftung erfolgt nun über den Ventilsitzbypass, bis das endgültige Kräftegleichgewicht erreicht ist.Particularly preferred is an arrangement of the damping element at the acted upon by the atmospheric pressure side of the eiektropneumatischen converter. As a result, the closing operation of the valve device can be delayed for a short time, whereby the behavior of the eiektropneumatischen converter is improved, especially in the small signal range, the valve plate of the bellows closes the vacuum tube, which can be designed in particular as a brass tube, and the ventilation takes place on the bellows over. The force introduced by the damping element on the armature causes the second valve seat integrated in the armature to be closed in a delayed manner. Due to the sealing surface of the bellows, the vacuum connection (negative pressure source / pump) is kept closed as long as possible to allow ventilation. Such an arrangement causes in particular an improved large and small signal behavior during the ventilation process, the connection to the atmosphere should remain open as long as possible. As a result, for example, a negative pressure can be reduced faster. When the differential pressure and force transferred to the armature by the electromagnet are approximately in equilibrium, the bellows valve plane closes both valve seats. The further venting is now via the valve seat bypass until the final equilibrium of forces is achieved.
In einer weiteren Ausführungsform kann das Dämpfungselement als Dämpfungsmembrane und insbesondere als Elastomerring ausgebildet sein, in der bzw, in dem der Anker gelagert ist.In a further embodiment, the damping element may be formed as a damping diaphragm and in particular as an elastomer ring, in or, in which the armature is mounted.

Die Membrane 20 ist ringförmig um den Ventilkörper 18 herumgeführt und in einer ringförmigen Ausnehmung des Gehäuses 32 bzw, eines Gehäusedeckels klemmend befestigt. Zwischen dem Ventiikörper 18 und dem Gehäuse 32 bzw. Gehäusedeckel weist die Membrane 20 einen im Wesentlichen bogenförmigen Verlauf auf. Die Membrane 20 ist am Ventilkörper 18 ebenfalls in einer Ausnehmung befestigt, die ringförmig um den Ventilkörper 18 herumfuhrt.The valve device 18,28 has a Veπtilköper 18 with a valve plate 28.

The armature 16 comprises a magnetic material and can be moved by applying an electric current to an electromagnet 17.
Die elektrische Spule des Elektromagneten 17 ist zur Bündelung der magnetischen Feldlinien von einer Eiseπummantelung 38 umgeben. Weiterhin ist zwischen dem Anker 16 und der Eisenummanteiung 38 ein Luftspalt 40 ausgebildet, in dem ein verstellbarer Eisenkern 34 derart angeordnet ist, dass die Länge des Luftspatts 40 veränderbar ist.

In Fign, 4 und 4a ist das Dämpfungselement 26 in demselben Hohlraum 24 als Feder ausgebildet.In Figs. 4 and 4a, the damping element 26 is formed in the same cavity 24 as a spring.
Fign. 5 und 5a zeigen an der gleichen Steile ein Dämpfungselement aus einem Schaumkörper.FIGS. 5 and 5a show at the same location a damping element made of a foam body.
In einer weiteren Ausführungsform gemäß Fig. 6 und 6a kann das Dämpfungselement als Dämpfungsmembrane 50 und insbesondere als Elastomerring ausgebildet sein, in der bzw. in dem der Anker 16 gelagert ist. Der Elastomerring weist vorzugsweise Silikon auf. Alternativ bzw. zusätzisch dazu können die Hubbewegungen des Ankers 16 sowie der Ventileinrichtung 18, 28 durch am Gehäuse 32 angebrachte Anschläge 44, 46, 48 gedämpft werden. Diese befinden sich vorzugsweise an der Steile des Gehäuses 32, auf die sich der Ventilkörper 18 bei einer Bewegung in Richtung der Kraft, die die Membrane 20 ausübt, zubewegt.In a further embodiment according to FIGS. 6 and 6 a, the damping element may be formed as a damping diaphragm 50 and in particular as an elastomer ring, in which or in which the armature 16 is mounted. The elastomeric ring preferably comprises silicone. Alternatively or additionally, the strokes of the armature 16 and the valve means 18, 28 can be damped by mounted on the housing 32 stops 44, 46, 48. These are preferably located at the location of the housing 32 to which the valve body 18 moves upon movement in the direction of the force exerted by the diaphragm 20.
Durch eine genaue Abstimmung der Lage der hubverhindernden bzw. hubmindernden Anschläge 44, 46, 48 sowie durch Abstimmung der Federkraft bzw, der Membrankraft ist es möglich, eine Anregungsbeschleunigung von 20 g zu realisieren, Besonders vorteilhaft ist dabei die Verwendung einer Dämpfungsmembrane 50 mit einer Dicke zwischen 2 mm und 3 mm, so dass Einschränkungen der Funktionen des elektropneumatischen Wandlers, wie beispielsweise Kennlinie (Neigung und Hysterese) bzw. Dynamik (Groß- und Kleinsigna!) minimiert werden können.By an exact adjustment of the position of the hubverhindernden or Hubmindernden stops 44, 46, 48 and by tuning the spring force or the membrane force, it is possible to realize an excitation acceleration of 20 g, Particularly advantageous is the use of a damping diaphragm 50 with a thickness between 2 mm and 3 mm, so that limitations of the functions of the electropneumatic converter, such as characteristic (inclination and hysteresis) or dynamics (large and small signal!) Can be minimized.
Alternativ oder zusätzlich dazu kann auch eine dickere Dämpfungsmembrane 50 verwendet werden, die Aussparungen aufweist und dadurch flexibler ausgebildet ist. Zur Aufnahme der Dämpfungsmembrane 50 weist der Ventilkörper 18 eine vorzugsweise ringförmige Nut 52 auf.Alternatively or additionally, a thicker damping membrane 50 can be used, which has recesses and is thus made more flexible. For receiving the damping diaphragm 50, the valve body 18 has a preferably annular groove 52.
Um einen Durchlass in Richtung des Atmosphärendruckanschlusses 12 zu erlauben, weist der Anschlag 46 eine nutförmige Ausnehmung 54 auf, durch die eine Belüftung stattfinden kann. Die Anschläge 46, 48 können beispielsweise aus Kunststoff ausgebildet sein.In order to allow a passage in the direction of the atmospheric pressure port 12, the stop 46 has a groove-shaped recess 54 through which ventilation can take place. The stops 46, 48 may be formed, for example, of plastic.
Zur zusätzlichen Dämpfung der Bewegung des Ventiikörpers 18 kann zwischen dem Ventilkörper 18 und dem Gehäuse 32 eine Feder 42 ausgebildet sein. Diese wird erfindungsgemäß in Verbindung mit weiteren Dämpfungseiementen 26, 50 verwendet. _ QFor additional damping of the movement of the Ventiikörpers 18 may be formed between the valve body 18 and the housing 32, a spring 42. This is inventively used in conjunction with other damping elements 26, 50. _Q
Es kann sowohl ein einzelnes Dämpfungselement, beispielsweise nur auf einer Seite des Ankers oder der Ventiieinrichtung, vorgesehen sein oder auch mehrere Dämpfungselemeπte, die auf einer oder auf mehreren Seiten des Ankers und der Ventiieinrichtung angeordnet sind, It can be provided both a single damping element, for example, only on one side of the armature or the Ventiieinrichtung, or even more Dämpfungselemeπte, which are arranged on one or more sides of the armature and the Ventiieinrichtung,
