Description
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
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
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
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:
- a) Versehen wenigstens eines Spulenkörpers mit wenigstens zwei separaten Drahtwicklungen,
- b) Verschalten von jeweils zwei Drahtwicklungen in Reihe oder parallel zueinander abhängig von der Betriebsspannung,
- c) Versehen des elektromagnetischen Ventils mit der entsprechend verschalteten Spule.
- a) providing at least one bobbin with at least two separate wire windings,
- b) interconnecting in each case two wire windings in series or in parallel depending on the operating voltage,
- 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.

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

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

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
