Description
Die Erfindung betrifft ein Tauchankersystem für einen elektropneumatischen Druckwandler, umfassend zumindest teilweise in einer Ummantelung, insbesondere Eisenummantelung, einen Tauchanker, einen Kern, wie einen Eisenkern oder einen Magnetkern, zumindest eine erste Ausnehmung in dem Tauchanker und/oder eine zweite Ausnehmung in dem Kern und einen Luftspalt zwischen der Ummantelung und dem Tauchanker und/oder dem Kern, der durch Relativbewegung zwischen dem Tauchanker und dem Kern, während der der Tauchanker in die zweite Ausnehmung in dem Kern und/oder der Kern in die erste Ausnehmung in dem Tauchanker zumindest teilweise hinein- bzw. aus derselben hinaus bewegbar ist, einstellbar ist.The invention relates to a submersible anchor system for an electropneumatic pressure transducer, comprising at least partially in a casing, in particular an iron casing, a Submersible anchor, a core, such as an iron core or a magnetic core, at least one first recess in the plunger anchor and / or a second recess in the core and an air gap between the casing and the plunger and / or the core, the by relative movement between the plunger and the core during which the Submersible anchor in the second recess in the core and / or the core in the first recess is at least partially movable in and out of the plunger, is adjustable.
Solch ein Tauchankersystem ist, beispielsweise, aus der DE 41 10 003 C1 bekannt. Dabei umfaßt der bekannte elektropneumatische Wandler, der insbesondere in einer pneumatischen Steuerung eines Kraftfahrzeuges einsetzbar ist, eine Ventileinrichtung, die von einer Membrane und dem Tauchankersystem betätigt wird und in einer Ventilkammer einen Mischdruck aus Luft mit niedrigem Druck und Atmosphärendruck durch Steuerung der entsprechenden Anschlüsse erzeugt, der über einen Anschluß einem Verbraucher zugeführt wird. Das Tauchankersystem zeichnet sich durch die Möglichkeit der Einstellung des Luftspalts zwischen der Eisenummantelung und dem Tauchanker, also im Magnetkreis, aus. Ferner erfüllt die Luft im Luftspalt Dämpfungseigenschaften, jedoch nur so lange, wie der Luftspalt mehr oder weniger abgedichtet ist, also keine Leckage aufweist. Eine Leckage wird bislang dadurch vermieden, daß zwischen dem Tauchanker und seinen Lagern eine Öl-Dichtung vorgesehen ist und das Tauchankersystem zumindest an seinem dem Tauchanker abgewandten Ende in Harz eingegossen ist. Nicht nur ist eine Öl-Dichtung sowie eine Harz-Einbettung arbeits- sowie kostenaufwendig herzustellen, sondern auch nicht ausreichend verläßlich zur Vermeidung einer Leckage, so daß im Betrieb des elektropneumatischen Druckwandlers ein Aneinanderstoßen von Tauchanker und Kern und somit Beschädigung derselben sowie hohe Geräuschemissionen auftreten können. Ferner weist Luft nachteiligerweise eine hohe Temperaturabhängigkeit auf, die sich ebenfalls auf Dämpfungseigenschaften derselben im Luftspalt negativ auswirken.Such an immersion anchor system is known, for example, from DE 41 10 003 C1. there includes the well-known electropneumatic converter, which is used in particular in a pneumatic Control of a motor vehicle can be used, a valve device by a membrane and the plunger system is actuated and in a valve chamber a mixed pressure from air at low pressure and atmospheric pressure by controlling the corresponding Connections generated, which is supplied to a consumer via a connection. The Submersible anchor system is characterized by the possibility of adjusting the air gap between the iron sheathing and the submersible anchor, i.e. in the magnetic circuit. Furthermore fulfilled the air in the air gap damping properties, but only as long as the air gap more or less sealed, so there is no leakage. So far there has been a leak avoided that an oil seal was provided between the plunger and its bearings and the submersible anchor system at least at its end facing away from the submersible anchor in Resin is poured. Not only is an oil seal and a resin embedding working as well costly to manufacture, but also not sufficiently reliable to avoid a leakage, so that a collision occurs during operation of the electropneumatic pressure transducer of submersible anchor and core and thus damage to the same as well as high noise emissions may occur. Furthermore, air disadvantageously has a high temperature dependence on, which also negatively affects the damping properties of the same in the air gap impact.
Aufgabe der vorliegenden Erfindung ist es daher, das gattungsgemäße Tauchankersystem derart weiterzuentwickeln, daß die Nachteile des Stands der Technik überwunden werden, insbesondere sicher ein metallischer Anschlag von Tauchanker und Kern vermieden wird zur Verhinderung einer mechanischen Beschädigung des Tauchankers und/oder Kerns sowie zur Reduktion einer Geräuschemission, insbesondere unter Schwingbeanspruchung bzw. bei Sprungfunktion, in einem großen Einsatzbereich.The object of the present invention is therefore the generic submersible anchor system to develop in such a way that the disadvantages of the prior art are overcome, in particular, a metallic stop of the submersible anchor and core is avoided Prevention of mechanical damage to the submersible anchor and / or core and for Reduction of noise emissions, especially under vibration or at Jump function, in a large area of application.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein erstes Dämpfungsglied in der ersten Ausnehmung und/oder ein zweites Dämpfungsglied in der zweiten Ausnehmung.This object is achieved according to the invention by a first attenuator in the first Recess and / or a second attenuator in the second recess.
Dabei ist bevorzugt, daß das erste und/oder zweite Dämpfungsglied aus einem Elastomer ausgebildet ist bzw. sind.It is preferred that the first and / or second damping member is formed from an elastomer is or are.
Vorteilhafte Ausführungsformen der Erfindung können dadurch gekennzeichnet sein, daß der Kern zweiteilig ausgebildet ist, die zweite Ausnehmung in dem ersten Kernteil ausgebildet ist, und der zweite Kernteil sich durch die zweite Ausnehmung hindurch erstreckt sowie in die erste Ausnehmung hinein- bzw. aus derselben heraus bewegbar ist.Advantageous embodiments of the invention can be characterized in that the Core is formed in two parts, the second recess is formed in the first core part, and the second core part extends through the second recess and into the first recess is movable in or out of the same.
Dabei kann vorgesehen sein, daß der erste Kernteil im wesentlichen ringförmig konzentrisch um den zweiten Kernteil ist, und das zweite Dämpfungsglied im wesentlichen ringförmig ist.It can be provided that the first core part is essentially concentric in a ring shape is around the second core portion and the second attenuator is substantially annular.
Ferner wird mit der Erfindung vorgeschlagen, daß der zweite Kernteil im wesentlichen zylinderförmig ist, und das erste Dämpfungsglied im wesentlichen stopfenartig ist. Furthermore, the invention proposes that the second core part be substantially cylindrical and the first attenuator is substantially plug-like.
Auch kann erfindungsgemäß vorgesehen sein, daß der Kern, insbesondere der erste Kernteil, über eine Gewindehülse relativ zum Tauchanker zur Einstellung des Luftspaltes bewegbar ist.It can also be provided according to the invention that the core, in particular the first core part, is movable via a threaded sleeve relative to the plunger to adjust the air gap.
Weiterhin wird erfindungsgemäß vorgeschlagen, daß der zweite Kernteil in dem ersten Kernteil verstellbar angeordnet ist, wobei der zweite Kemteil vorzugsweise an seinem dem Tauchanker abgewandten Ende zum Einstellen des Luftspaltes angreifbar ist.Furthermore, it is proposed according to the invention that the second core part in the first core part is arranged adjustable, the second core part preferably at its the End facing away from the plunger anchor can be attacked for adjusting the air gap.
Es wird erfindungsgemäß auch vorgeschlagen, daß der erste und/oder zweite Kernteil einen in Richtung des Tauchankers sich verjüngenden Konusabschnitt aufweist bzw. aufweisen.It is also proposed according to the invention that the first and / or second core part have a Has or have tapered cone section in the direction of the plunger.
Ferner kann eine Gleitlagerbuchse für den Tauchanker erfindungsgemäß vorgesehen sein.Furthermore, a plain bearing bush for the plunger anchor can be provided according to the invention.
Schließlich kann auch ein Abstandshalter zwischen der Ummantelung und der Gewindehülse erfindungsgemäß vorgesehen sein.Finally, there can also be a spacer between the casing and the threaded sleeve be provided according to the invention.
Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß auf kostengünstige Weise die Abnutzung eines Tauchankersystems verringert und der Einsatzbereich desselben vergrößert werden kann, indem der Luftspalt des Magnetkreises in einem elektropneumatischen Druckwandler im wesentlichen nur noch der Funktion der Einstellung des elektropneumatischen Druckwandlers dient, während Dämpfungseigenschaften von zumindest einem zusätzlichen Dämpfungsglied übernommen werden, das zwischen dem Tauchanker und dem Kern vorgesehen ist, nämlich in einer Ausnehmung in dem Kern und/oder in einer Ausnehmung in dem Tauchanker. Das Dämpfungsglied verhindert dabei sicher einen metallischen Anschlag von Tauchanker und Kern, ohne daß eine aufwendige Dichtung des Luftspalts vorliegen muß; das Dämpfungsglied dämpft zudem Schall zur Reduktion der Geräuschemission des elektropneumatischen Druckwandlers; und das Dämpfungsglied ist vorzugsweise aus einem Elastomer ausgebildet, das eine geringe Temperaturabhängigkeit aufweist und somit den Einsatzbereich des elektropneumatischen Druckwandlers vergrößert.The invention is therefore based on the surprising finding that inexpensive How the wear of a submersible anchor system is reduced and its area of use can be enlarged by the air gap of the magnetic circuit in an electropneumatic Pressure converter essentially only the function of setting the electro-pneumatic Pressure transducer is used while damping properties of at least one additional attenuator are taken over between the plunger and the Core is provided, namely in a recess in the core and / or in a recess in the diving anchor. The attenuator reliably prevents a metallic one Stop of the submersible anchor and core without the need for a complex air gap seal got to; the attenuator also attenuates sound to reduce noise emissions the electropneumatic pressure transducer; and the attenuator is preferably made of one Formed elastomer, which has a low temperature dependence and thus the Application area of the electropneumatic pressure transducer enlarged.

Wie der Figur zu entnehmen ist, umfaßt ein erfindungsgemäßes Tauchankersystem 1 innerhalb
einer Spule 2 einen Tauchanker 10 mit einer ersten Ausnehmung 12 an seinem einer
nicht gezeigten Membrane des elektropneumatischen Druckwandlers abgewandten Ende. Die
erste Ausnehmung 12 ist dabei im wesentlichen zylinderförmig mit einem sich konisch verjüngenden
Ende. Der Tauchanker 10 verläuft zumindest zum Teil in einer Eisenummantelung
14, die ebenfalls die Spule 2 und zumindest einen Teil eines Eisenkerns umschließt. Der Eisenkern
seinerseits umfaßt zwei Komponenten, wobei ein erster Eisenkernteil 16 mit einer
zweiten Ausnehmung 18 ausgebildet ist, in der der zweite Eisenkernteil 20 verläuft. Der
Tauchanker 10 ist ferner in einer Gleitlagerbuchse 22 in der Eisenummantelung 14 geführt,
während der erste Eisenkernteil 16 in einer Gewindehülse 24 gelagert ist, die ihrerseits von
einem Anstoßen an die Eisenummantelung 14 durch einen Abstandshalter 26 bewahrt wird. In
der ersten Ausnehmung 12 in dem Tauchanker 10 ist ein Dämpfungsstopfen 28, insbesondere
in Form eines die erste Ausnehmung 12 teilweise füllenden Elastomers, angeordnet, und in
der zweiten Ausnehmung 18 in dem ersten Eisenkern 16 ist ein Dämfungsring 30, insbesondere
in Form eines die zweite Ausnehmung 18 teilweise füllenden Elastomers, angeordnet.
Ein Luftspalt 32 ist schließlich zwischen dem Tauchanker 10, dem Abstandshalter 26 und
dem Eisenkern 16, 18 ausgebildet. Die Größe des Luftspaltes 32 ist dabei zur Einjustierung
des elektropneumatischen Druckwandlers durch Bewegung des ersten Eisenkemteils 16,
nämlich durch Drehung an der Gewindehülse 24, und/oder Bewegung des zweiten Eisenkemteils
20, nämlich durch Drehung desselben in dem zweiten Eisenkernteil 20, relativ zum
Tauchanker 10 möglich.As can be seen from the figure, an
Im Betrieb eines elektropneumatischen Druckwandlers mit dem erfindungsgemäßen
Tauchankersystem 1 verhindern der Dämpfungsring 28 und der Dämpfungsstopfen 30 einen
metallischen Anschlag des ersten Eisenkerns 16 bzw. des zweiten Eisenkerns 20 an den
Tauchanker 10, was zum einen die durchschnittliche Lebenszeit des Tauchankersystems 1
aufgrund der Reduktion einer Beschädigung erhöht und zum anderen die Geräuschemission
reduziert, und zwar vorteilhafterweise über einen großen Temperaturbereich aufgrund der
geringen Temperaturabhängigkeit des für den Dämpfungsring 28 sowie den Dämpfungsstopfen
30 verwendeten Elastomers.In operation of an electropneumatic pressure converter with the invention
