Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem elektromagnetischen Ventil mit wenigstens einer Spule beinhaltend wenigstens einen Spulenkörper, gemäß dem Oberbegriff von Anspruch 1 sowie ein Verfahren zu ihrer Herstellung gemäß Anspruch 4.The invention is based on an electromagnetic valve with at least one coil including at least one bobbin, according to the preamble of claim 1 and a method for their preparation according to claim 4.

In elektromagnetischen Ventilen werden elektromagnetische Spulen eingesetzt, um mittels elektromagnetischer Kräfte mit Ventilsitzen zusammenwirkende Ventilkörper zu steuern. Solche elektromagnetischen Ventile finden beispielsweise in elektronisch geregelten Bremssystemen (EBS) von Nutzfahrzeugen Anwendung und schalten oder steuern abhängig von ihrer Bestromung Brems- oder Steuerdrücke.In electromagnetic valves electromagnetic coils are used to control by means of electromagnetic forces with valve seats cooperating valve body. Such electromagnetic valves are used, for example, in electronically controlled brake systems (EBS) of commercial vehicles and switch or control depending on their current supply braking or control pressures.

Je nach dem Einsatzumfeld werden diese Ventile mit unterschiedlichen Betriebsspannungen beaufschlagt. Bei in den USA verwendeten Nutzfahrzeugen ist eine Bordspannung von 12 Volt üblich, in Europa beträgt diese Spannung in der Regel aber 24 Volt. Mit Ausnahme der unterschiedlichen Betriebsspannungen sollen die Leistungsdaten der 12 Volt- und 24 Volt-Magnetventile aber im wesentlichen identisch sein.Depending on the application environment, these valves are subjected to different operating voltages. In commercial vehicles used in the United States, an on-board voltage of 12 volts is common, but in Europe this voltage is usually 24 volts. However, with the exception of the different operating voltages, the performance of the 12 volt and 24 volt solenoid valves should be essentially identical.

Bisher wird bei den Spulen für 12 Volt-Magnetventile jeweils eine einstückige Drahtwicklung mit einem Drahtdurchmesser von ca. 0,3 bis 0,5 mm mit einer relativ hohen Anzahl von Windungen verwendet, um eine geforderte elektrische und/oder magnetische Mindestleistung zu erreichen. Dadurch baut eine solche Spule relativ groß. Zum Erzielen annährend identischer Leistungswerte wird bei den Spulen für 24 Volt-Magnetventile demgegenüber ein Spulendraht mit kleinerem Drahtdurchmesser von ca. 0,2 bis 0,3 mm eingesetzt, wodurch die 24 Volt-Spulen ca. 20% kleiner bauen als die 12 Volt-Spulen. Dadurch bedingt sind die jeweiligen Aufnahmen für die unterschiedlich großen Spulen an ansonsten identisch aufgebauten Magnetventilen mit unterschiedlichen Maßen auszuführen, was den Fertigungsaufwand unvorteilhaft erhöht.So far, in the coils for 12 volt solenoid valves each have a one-piece wire winding with a wire diameter of about 0.3 to 0.5 mm with a relatively high number of turns used to achieve a required electrical and / or magnetic minimum power. As a result, builds such a coil relatively large. In contrast, to achieve approximately identical power values, the coil for 24 volt solenoid valves uses a coil wire with a smaller wire diameter of approximately 0.2 to 0.3 mm, which makes the 24 volt coils approximately 20% smaller than the 12 volt coils. Do the washing up. As a result, the respective receptacles for the different sized coils to otherwise identical identically designed solenoid valves with different dimensions, which increases the manufacturing cost unfavorably.

Weiterhin werden solche, in elektronischen geregelten Bremssystemen (EBS) verwendeten Magnetventile in der Regel in sog. Druckregelmoduln als Einlass-Auslass- und Backupventilkombination eingesetzt, welche rad- bzw. achsnah verbaut sind, wo üblicherweise nur wenig Bauraum zur Verfügung steht. Deshalb besteht ein Bedürfnis nach möglichst klein bauenden Magnetventilen. Dasselbe gilt auch für Magnetventile für andere Anwendungen, beispielsweise für Magnetventile in Getriebesteuerungen.Furthermore, such solenoid valves used in electronic regulated brake systems (EBS) are usually used in so-called. Pressure control modules as inlet-outlet and backup valve combination, which are installed close to the wheel or near the axis, where usually only little space is available. Therefore, there is one Need for as small as possible solenoid valves. The same applies to solenoid valves for other applications, such as solenoid valves in transmission controls.

Aus der gattungsbildenden DE 197 41 570 A1 sind Magnetspulen bekannt, welche während des Betriebs in einer elektromagnetischen Stelleinrichtung abhängig vom Drehzahlbereich und Betriebsmodus (Schalten oder Halten der Magnete) einzeln, parallel oder in Reihe geschaltet angesteuert, jeweils mit anderem Spannungsniveau. Damit ergeben sich allerdings unterschiedliche elektrische Leistungen.From the generic DE 197 41 570 A1 Magnetic coils are known, which during operation in an electromagnetic actuator depending on the speed range and operating mode (switching or holding the magnets) individually, driven in parallel or in series, each with a different voltage level. However, this results in different electrical services.

Der vorliegenden Erfindung liegt demgegenüber die Aufgabe zugrunde, ein elektromagnetisches Ventil der eingangs erwähnten Art derart weiterzubilden, dass es bei möglichst kleinem Bauraum ohne größere Veränderungen mit unterschiedlichen Betriebsspannungen betrieben werden kann und dabei trotzdem im wesentlichen identische Leistungsdaten wie elektrische Leistung und/oder magnetische Leistung liefert. Darüber hinaus ist ein Verfahren zu seiner Herstellung anzugeben.The present invention is based on the object, an electromagnetic valve of the type mentioned in such a way that it can be operated in the smallest possible space without major changes with different operating voltages and still delivers substantially identical performance data such as electrical power and / or magnetic power , In addition, a method for its production must be specified.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale von Anspruch 1 und Anspruch 4 gelöst.According to the invention, this object is solved by the features of claim 1 and claim 4.

Vorteile der ErfindungAdvantages of the invention

Die Erfindung basiert auf dem Gedanken, dass der Spulenkörper der Spule des elektromagnetischen Ventils mit wenigstens zwei separaten Drahtwicklungen versehen wird, von welchen jeweils zwei in Reihe oder parallel zueinander verschaltet sind. Dies beinhaltet beispielsweise nur zwei Drahtwicklungen, die in Reihe oder parallel verschaltet sind. Darüber hinaus ist eine Vielzahl von Kombinationen denkbar, beispielsweise vier Drahtwicklungen, von welchen die erste und die zweite Drahtwicklung parallel, die zweite und dritte Drahtwicklung inThe invention is based on the idea that the bobbin of the coil of the electromagnetic valve is provided with at least two separate wire windings, two of which are connected in series or parallel to each other. This includes, for example, only two wire windings connected in series or in parallel. In addition, a variety of combinations are conceivable, for example, four wire windings, of which the first and the second wire winding parallel, the second and third wire winding in

Reihe und die dritte und vierte Drahtwicklung wieder parallel zueinander verschaltet sind.Row and the third and fourth wire winding are connected in parallel again.

Insbesondere werden die Anzahl und die Wicklungsparameter der Drahtwicklungen wie Drahtdurchmesser und/oder Windungszahl derart gewählt, dass abhängig von der Verschaltung ihrer Drahtwicklungen die mit vorbestimmten unterschiedlichen Betriebsspannungen beaufschlagte Spule im wesentlichen identische elektrische und magnetische Kenngrößen wie elektrische Leistung und/oder magnetische Leistung liefert.In particular, the number and the winding parameters of the wire windings, such as wire diameter and / or number of windings, are chosen such that, depending on the wiring of their wire windings, the wind applied to predetermined different operating voltages supplies substantially identical electrical and magnetic characteristics, such as electrical power and / or magnetic power.

Beispielsweise kann für die Drahtwicklung einer Spule für ein 12 Volt-Magnetventil ein gegenüber dem Stand der Technik dünnerer Draht verwendet werden, insbesondere mit einem Drahtdurchmesser, welcher demjenigen der Drahtwicklung einer Spule eines 24 Volt-Magnetventils entspricht. Bei zusätzlich gleicher Windungszahl der Drahtwicklung wie bei der Spule des 24 Volt-Magnetventils ergibt sich dann, Spulenkörper gleicher Größe vorausgesetzt, eine Spule für ein 12 Volt-Magnetventil, welche die gleiche Größe hat wie die Spule für ein 24 Volt-Magnetventil, so dass die Spulenaufnahmen und insbesondere die Spulenbohrungen in den Ventilgehäusen der elektromagnetischen Ventile mit identischen geometrischen Maßen ausgebildet werden können.For example, for the wire winding of a coil for a 12 volt solenoid valve, a thinner wire than the prior art may be used, in particular with a wire diameter which corresponds to that of the wire winding of a coil of a 24 volt solenoid valve. In addition, with the same number of turns of the wire winding as in the coil of the 24 volt solenoid valve results then, coil body of the same size provided, a coil for a 12 volt solenoid valve, which has the same size as the coil for a 24 volt solenoid valve, so that the coil receptacles and in particular the coil bores in the valve housings of the electromagnetic valves can be formed with identical geometrical dimensions.

Da sich von der Spule abgesehen die restlichen Bauteile eines 12 Volt-Magnetventils und im 24 Volt-Magnetventils möglichst nicht voneinander unterscheiden und die Schaltcharakteristiken in beiden Fällen möglichst identisch sein sollen, sind annährend identische elektrische Größen wie beispielsweise die elektrische Leistung und magnetische Leistung der Spulen im 12 Volt-Magnetventil und im 24 Volt-Magnetventil wünschenswert.As apart from the coil, the remaining components of a 12 volt solenoid valve and the 24 volt solenoid valve as possible not differ from each other and the switching characteristics should be identical in both cases as possible, are approximately identical electrical variables such as the electrical power and magnetic power of the coils in the 12 volt solenoid valve and in the 24 volt solenoid valve desirable.

Dies wird gemäß der Erfindung dadurch realisiert, dass für eine Ausführung beispielsweise als 12 Volt-Magnetventil die ursprünglich einstückige Drahtwicklung mit dickem Draht in zwei gleich große separate Drahtwicklungen getrennt wird, welche parallel zueinander geschaltet werden. Hingegen werden die beiden Drahtwicklungen für die Spule des 24 Volt-Magnetventils in Reihe geschaltet. Der einzige Unterschied zwischen einer Spule für ein 12 Volt-Magnetventil und einer Spule für ein 24 Volt-Magnetventil besteht folglich lediglich in der jeweiligen Verschaltung der beiden Drahtwicklungen, was fertigungstechnisch eine äußerst einfache Maßnahme darstellt. Der restliche Aufbau der Spulen wie beispielsweise die Windungszahl, der Drahtdurchmesser oder der Spulenkörper ist ansonsten identisch, was auch die gleiche Baugröße der Spulen untereinander bedingt.This is realized according to the invention in that for an embodiment, for example, as a 12 volt solenoid valve, the originally one-piece wire winding with thick wire is separated into two equal-sized separate wire windings, which are connected in parallel. On the other hand, the two wire windings for the coil of the 24 volt solenoid valve are connected in series. Of the The only difference between a coil for a 12 volt solenoid valve and a coil for a 24 volt solenoid valve is therefore only in the respective interconnection of the two wire windings, which is an extremely simple production technology. The rest of the structure of the coils such as the number of turns, the wire diameter or the bobbin is otherwise identical, which also causes the same size of the coil with each other.

Ein Verfahren zur Herstellung des beschriebenen elektromagnetischen Ventils beinhaltet wenigstens folgende Schritte:

  1. a) Versehen wenigstens eines Spulenkörpers mit wenigstens zwei separaten Drahtwicklungen,
  2. b) Verschalten von jeweils zwei Drahtwicklungen in Reihe oder parallel zueinander abhängig von der Betriebsspannung,
  3. c) Versehen des elektromagnetischen Ventils mit der entsprechend verschalteten Spule.
A method for producing the described electromagnetic valve includes at least the following steps:
  1. a) providing at least one bobbin with at least two separate wire windings,
  2. b) interconnecting in each case two wire windings in series or in parallel depending on the operating voltage,
  3. c) providing the electromagnetic valve with the appropriately interconnected coil.

Folglich können mit Hilfe der Erfindung durch Einsetzen einer lediglich durch entsprechendes Verschalten der beiden Drahtwicklungen an die jeweils geforderte Betriebsspannung angepasste und ansonsten standardisierte Spule in ein ebenfalls standardisiertes Magnetventil Magnetventiltypen für unterschiedliche Betriebsspannungen, aber gleicher Leistungsdaten realisiert werden. Dies erspart eine teure Fertigung und Lagerhaltung unterschiedlicher Spulen und Magnetventile.Consequently, with the aid of the invention, magnet valve types for different operating voltages, but the same performance data, can be implemented by inserting an otherwise standardized coil into a likewise standardized solenoid valve, merely by correspondingly connecting the two wire windings to the respectively required operating voltage. This saves expensive production and storage of different coils and solenoid valves.

Bei gleichem Bauraum für die Spule ergibt sich eine höhere elektrische Leistung oder bei gleicher Leistung der Spule ein kleinerer Bauraum gegenüber dem Stand der Technik. Dies spart insbesondere Kupferdraht, wodurch die Herstellkosten der Magnetventile gesenkt werden.With the same space for the coil results in a higher electrical power or the same power of the coil a smaller space compared to the prior art. This saves in particular copper wire, whereby the manufacturing costs of the solenoid valves are lowered.

Die Erfindung wird anhand des im folgenden ausführlich beschriebenen Ausführungsbeispiels besonders deutlich.The invention will be particularly apparent from the embodiment described in detail below.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Fig.1 ist mit der Bezugszahl 1 eine Spule eines ansonsten nicht gezeigten elektromagnetischen Ventils gezeigt, wie es beispielsweise in einem Druckregelmodul einer elektronisch geregelten Bremsvorrichtung (EBS) eines Nutzfahrzeugs verwendet wird. Die Spule sei beispielsweise für ein 12 Volt-Magnetventil vorgesehen, d.h. ihre Betriebsspannung beträgt 12 Volt, weil das Bordnetz des Nutzfahrzeugs für diese Spannung ausgelegt ist.In Fig.1 the reference numeral 1 shows a coil of an electromagnetic valve, not shown otherwise, as used for example in a pressure control module of an electronically controlled braking device (EBS) of a commercial vehicle. The coil is for example provided for a 12 volt solenoid valve, ie its operating voltage is 12 volts, because the electrical system of the commercial vehicle is designed for this voltage.

Die Spule beinhaltet beispielsweise zwei, vorzugsweise hinsichtlich der Wicklungsparameter wie Windungszahl, Drahtdurchmesser, Drahtquerschnitt (rund, eckig) und Drahtmaterial identische, aber separate Drahtwicklungen 2, 4 aus üblichem Kupferdraht, welche auf einem vorzugsweise einstückigen, hier nicht gezeigten Spulenkörper aufgewickelt sind. Alternativ könnte der Spulenkörper auch mehrteilig sein, oder jede Drahtwicklung 2, 4 ist einem eigenen Spulenkörper zugeordnet.The coil includes, for example, two, preferably in terms of winding parameters such as number of turns, wire diameter, wire cross-section (round, square) and wire material identical but separate wire windings 2, 4 of conventional copper wire, which are wound on a preferably one-piece, not shown here bobbin. Alternatively, the bobbin could also be multi-part, or each wire winding 2, 4 is associated with its own bobbin.

Die Enden 6 der Drahtwicklungen 2, 4 sind aus diesen derart herausgeführt, dass die beiden Drahtwicklungen 2, 4 entweder in Reihe oder parallel zueinander verschaltet werden können. Der Durchmesser des Spulendrahts beträgt beispielsweise 0,2 mm bis 0,3 mm. Im vorliegenden Fall einer 12 Volt Betriebsspannung werden die beiden Drahtwicklungen 2, 4 parallel zueinander verschaltet, beispielsweise dadurch, dass die aus den Drahtwicklungen 2, 4 herausgeführten Enden 6 auf einer Leiterplatte miteinander entsprechend verbunden werden.The ends 6 of the wire windings 2, 4 are led out of these so that the two wire windings 2, 4 can be connected either in series or in parallel to each other. The diameter of the coil wire is, for example, 0.2 mm to 0.3 mm. In the present case of a 12 volt operating voltage, the two wire windings 2, 4 parallel to each other interconnected, for example, characterized in that the led out of the wire windings 2, 4 ends 6 are connected to each other on a circuit board accordingly.

Jede der beiden Drahtwicklungen 2, 4 weist beispielsweise einen Widerstand von 4 Ohm und eine Windungszahl von 100 auf, so dass für den Gesamtwiderstand Rges der Parallelschaltung gemäß Fig.1 gilt: 1 Rges = 1 R 1 + 1 R 2 = 1 4 + 1 4 = 2 4 ; Rges = 2 Ohm

Figure imgb0001
Each of the two wire windings 2, 4 has, for example, a resistance of 4 ohms and a winding number of 100, so that for the total resistance R ges of the parallel circuit according to FIG Fig.1 applies: 1 Rges = 1 R 1 + 1 R 2 = 1 4 + 1 4 = 2 4 ; Rges = 2 ohm
Figure imgb0001

Dann gilt für die elektrische Leistung der Spule 1: P elektr = U 2 R ges = 12 2 2 = 72 W / t

Figure imgb0002

bzw. für die magnetische Leistung : P magn = U R * N = 12 V 4 Ohm * 2 * 100 = 600 V Ohm
Figure imgb0003
Then applies to the electrical power of the coil 1: P Electric = U 2 R ges = 12 2 2 = 72 W / t
Figure imgb0002

or for the magnetic power: P magn = U R * N = 12 V 4 ohm * 2 * 100 = 600 V ohm
Figure imgb0003

Soll die gleiche Spule 1 für eine Betriebsspannung von 24 Volt eingesetzt werden und die Leistungsdaten identisch sein, werden die Enden 6 der Drahtwicklungen 2, 4 derart auf der Leiterplatte miteinander verbunden, dass die beiden Drahtwicklungen 2, 4 in Reihe verschaltet sind, wie in Fig.2 gezeigt ist. Dann gilt für den Gesamtwiderstand Rges : R ges = R 1 + R 2 = 4 + 4 = 8 Ohm

Figure imgb0004
If the same coil 1 is to be used for an operating voltage of 24 volts and the performance data are identical, the ends 6 of the wire windings 2, 4 are connected to one another on the printed circuit board such that the two wire windings 2, 4 are connected in series, as in FIG Fig.2 is shown. Then the total resistance R ges applies: R ges = R 1 + R 2 = 4 + 4 = 8th ohm
Figure imgb0004

Dann gilt für die elektrische Leistung der Spule 1: P elektr = U 2 R ges = 24 2 8 = 72 W / t

Figure imgb0005

bzw. für die magnetische Leistung : P magn = U R * N = 24 V 8 Ohm * 200 = 600 V Ohm
Figure imgb0006
Then applies to the electrical power of the coil 1: P Electric = U 2 R ges = 24 2 8th = 72 W / t
Figure imgb0005

or for the magnetic power: P magn = U R * N = 24 V 8th ohm * 200 = 600 V ohm
Figure imgb0006

Infolgedessen weist die Spule 1 unter unterschiedlichen Betriebsspannungen, hier beispielsweise 12 Volt und 24 Volt, in paralleler Verschaltung und in Reihenschaltung ihrer beiden Drahtwicklungen 2, 4 im wesentlichen identische elektrische Kenngrößen wie elektrische Leistung und/oder magnetische Leistung auf und bildet somit eine standardisierte Baueinheit zur Verwendung in Magnetventilen mit 12 Volt und mit 24 Volt Betriebsspannung. Dann können auch die Spulenaufnahmen eines 12 Volt-Magnetventils bzw. eines 24 Volt-Magnetventils, welche in der Regel jeweils durch eine Spulenbohrung im Ventilgehäuse gebildet werden, identische Maße aufweisen. Dadurch bildet ein solches 12 Volt- bzw. 24 Volt-Magnetventil wiederum eine standardisierte Baueinheit, da sich von der Verschaltung der Drahtwicklungen 2, 4 der Spule 1 abgesehen die restlichen Bauteile des 12-Volt-Magnetventils und des 24-Volt-Magnetventils nicht voneinander unterscheiden.As a result, the coil 1 under different operating voltages, here for example 12 volts and 24 volts, in parallel connection and in series of their two wire windings 2, 4 substantially identical electrical parameters such as electrical power and / or magnetic power and thus forms a standardized unit Used in solenoid valves with 12 Volt and 24 Volt operating voltage. Then, the coil recordings of a 12 volt solenoid valve or a 24 volt solenoid valve, which are usually each formed by a coil bore in the valve housing, have identical dimensions. As a result, such a 12 volt or 24 volt solenoid valve in turn forms a standardized unit, as apart from the interconnection of the wire windings 2, 4 of the coil 1, the remaining components of the 12-volt solenoid valve and the 24-volt solenoid valve not from each other differ.

Die Erfindung ist nicht auf das Ausführungsbeispiel mit zwei separaten Drahtwicklungen 2, 4 auf dem Spulenkörper beschränkt. Vielmehr können abhängig von den jeweils vorgegebenen Betriebsspannungen mehr als zwei separate Drahtwicklungen vorgesehen sein, welche auch unterschiedliche Wicklungsparameter wie Windungszahl, Drahtdurchmesser etc. aufweisen können. Die Anzahl und Verschaltung der einzelnen Drahtwicklungen sowie deren Wicklungsparameter werden vom Fachmann abhängig von dem geforderten elektrischen und magnetischen Leistungsverhalten und insbesondere von den vorgegebenen Betriebsspannungen fallweise angepasst.The invention is not limited to the embodiment with two separate wire windings 2, 4 on the bobbin. Rather, more than two separate wire windings may be provided depending on the respective predetermined operating voltages, which may also have different winding parameters such as number of turns, wire diameter, etc. The number and interconnection of the individual wire windings and their winding parameters are adjusted by the skilled person depending on the required electrical and magnetic performance and in particular of the specified operating voltages on a case by case basis.

Besonders bevorzugt sind die Drahtwicklungen auf dem Spulenkörper 10 übereinander gewickelt, wie aus Fig.3 hervorgeht. Dort ist auf dem einen Spulenkern 8 umschließenden Spulenkörper 10 als innerste Lage eine erste Drahtwicklung 2 aufgewickelt. Diese erste Drahtwicklung 2 ist wiederum von einer zweiten Drahtwicklung 4 umwickelt und Letztere wiederum von einer dritten Drahtwicklung 12.Particularly preferably, the wire windings are wound on the bobbin 10 one above the other, as seen from Figure 3 evident. There is wound on the one coil core 8 enclosing bobbin 10 as the innermost layer, a first wire winding 2. This first wire winding 2 is in turn wrapped by a second wire winding 4 and the latter in turn by a third wire winding 12th
