Description
Die Erfindung betrifft einen Magnetanker und ein Verfahren zum Herstellen eines Magnetankers, insbesondere eines Magnetankers für ein elektromagnetisches Schaltventil, das in einer Vorrichtung zum Einspritzen eines fluiden Reduktionsmittels in einen Abgasstrang eines Verbrennungsmotors zum Einsatz kommt.The invention relates to a magnet armature and a method for producing a magnet armature, in particular a magnet armature for an electromagnetic switching valve, which is used in a device for injecting a fluid reducing agent into an exhaust line of an internal combustion engine.
Stand der TechnikState of the art
Zum Entsticken der Abgase von Verbrennungsmotoren, insbesondere von Dieselmotoren, hat sich die SCR-Technik („selective catalytic reduction“) bewährt. Für diese Technik wurden Systeme entwickelt, welche die Einhaltung der geforderten Abgasgrenzwerte durch eine definierte Zugabe einer wässrigen Harnstofflösung („AdBlue“) als Reduktionsmittel in den Abgasstrang des Verbrennungsmotors und die Reduktion der Stickoxide in einem anschließenden SCR-Katalysator ermöglichen. Diese Systeme umfassen im Wesentlichen einen Reduktionsmitteltank zum Speichern des Reduktionsmittels, ein am Abgasstrang des Verbrennungsmotors angeordnetes Dosiermodul, eine Pumpvorrichtung, die ausgebildet ist, das Reduktionsmittel aus dem Reduktionsmitteltank zum Dosiermodul zu fördern, und ein elektronisches Steuergerät.To de-sting the exhaust gases of internal combustion engines, especially diesel engines, the SCR technology ("selective catalytic reduction") has proven itself. For this technique, systems have been developed which allow compliance with the required exhaust emission limits by a defined addition of an aqueous urea solution ("AdBlue") as a reducing agent in the exhaust line of the internal combustion engine and the reduction of nitrogen oxides in a subsequent SCR catalyst. These systems essentially comprise a reducing agent tank for storing the reducing agent, a metering module arranged at the exhaust gas line of the internal combustion engine, a pumping device designed to convey the reducing agent from the reducing agent tank to the metering module, and an electronic control unit.
Wässrige Harnstofflösung gefriert bei Temperaturen unterhalb von -11 °C. Der Gefrierpunkt kann nicht weiter gesenkt werden, ohne die Funktionsfähigkeit als Reduktionsmittel zu beeinträchtigen. Um beim Einfrieren des Reduktionsmittels nicht durch den dabei entstehenden Eisdruck beschädigt zu werden, muss das Dosiermodul eines solches System im abgestellten Zustand vollständig entleert werden. Dazu kann insbesondere ein Schaltventil vorgesehen sein, das es ermöglicht, die Pumpvorrichtung als Rücksaugpumpe zu betreiben, um das Reduktionsmittel aus dem Dosiermodul zurück in den Reduktionsmitteltank zu fördern.Aqueous urea solution freezes at temperatures below -11 ° C. The freezing point can not be lowered further without impairing the functionality as a reducing agent. In order not to be damaged by the resulting ice pressure when freezing the reducing agent, the metering module of such a system must be completely emptied when parked. For this purpose, in particular, a switching valve can be provided, which makes it possible to operate the pumping device as a suction pump to promote the reducing agent from the dosing back into the reducing agent tank.
Ein solches Schaltventil weist üblicherweise einen Magnetanker auf, der durch ein- und ausschaltbares elektromagnetisches Feld beweglich ist.Such a switching valve usually has a magnetic armature, which is movable by switchable on and off electromagnetic field.
Es ist eine Aufgabe der Erfindung, ein solches Schaltventil und insbesondere einen solchen Magentanker zu verbessern und seinen Herstellungsprozess zu vereinfachen.It is an object of the invention to improve such a switching valve and in particular such a gas tanker and to simplify its manufacturing process.
Offenbarung der ErfindungDisclosure of the invention
Gemäß einem Ausführungsbeispiel der Erfindung umfasst ein Verfahren zum Herstellen eines Magnetankers, insbesondere eines Magnetankers für ein Schaltventil, eine Korrosionsschutzschicht derart auf ein Grundmaterial aufzubringen, dass sich zumindest an der Oberfläche der Korrosionsschutzschicht Poren ausbilden, und ein Gleitmaterial auf die Korrosionsschutzschicht aufzubringen, ohne die Poren, die in der Korrosionsschutzschicht ausgebildet sind, vor dem Aufbringen eines Gleitmaterials zu verschließen.According to one exemplary embodiment of the invention, a method for producing a magnet armature, in particular a magnet armature for a switching valve, comprises applying a corrosion protection layer to a base material such that pores are formed at least on the surface of the anticorrosion layer and applying a sliding material to the anticorrosive layer, without the pores , which are formed in the anticorrosion layer, to close before applying a sliding material.
Ein Magnetanker, insbesondere für ein Schaltventil, umfasst gemäß einem Ausführungsbeispiel der Erfindung ein Grundmaterial, eine auf das Grundmaterial aufgebrachte Korrosionsschutzschicht, die Poren enthält; und ein auf die Korrosionsschutzschicht aufgebrachtes Gleitmaterial. Dabei sind die Poren der Korrosionsschutzschicht vor dem Aufbringen des Gleitmaterials nicht verschlossen worden.A magnet armature, in particular for a switching valve, according to an embodiment of the invention, comprises a base material, a corrosion protection layer applied to the base material and containing pores; and a lubricant applied to the anticorrosion layer. The pores of the anticorrosion layer have not been sealed before the application of the sliding material.
Die Erfindung umfasst auch ein elektromagnetisches Schaltventil mit einem Magnetanker gemäß einem Ausführungsbeispiel der Erfindung sowie eine Vorrichtung zum Einspritzen eines fluiden Reduktionsmittels in einen Abgasstrang eines Verbrennungsmotors, mit einem Reduktionsmitteltank, der zur Speicherung des fluiden Reduktionsmittels ausgebildet ist; einem Dosiermodul, das an dem Abgasstrang angebracht und ausgebildet ist, das Reduktionsmittel dosiert in den Abgasstrang einzuspritzen; einer Pumpvorrichtung, die ausgebildet ist, in einem Förderbetrieb Reduktionsmittel aus dem Reduktionsmitteltank zu dem Dosiermodul zu fördern und in einem Rücksaugbetrieb Reduktionsmittel aus dem Dosiermodul in den Reduktionsmitteltank zu fördern. Auch die Leitungen, die das Dosiermodul mit der Pumpvorrichtung verbinden und die Pumpvorrichtung selbst können geleert werden. Die Vorrichtung umfasst auch ein elektromagnetisches Schaltventil, das es ermöglicht, den Betrieb der Vorrichtung zwischen dem Förderbetrieb und dem Rücksaugbetrieb umzuschalten, wobei das elektromagnetische Schaltventil einen Magnetanker gemäß einem Ausführungsbeispiel der Erfindung hat.The invention also includes an electromagnetic switching valve with a magnetic armature according to an embodiment of the invention and a device for injecting a fluid reducing agent into an exhaust line of an internal combustion engine, with a reducing agent tank, which is designed to store the fluid reducing agent; a metering module, which is attached to the exhaust line and is adapted to inject the reducing agent metered into the exhaust gas line; a pumping device, which is designed to promote reductant from the reducing agent tank to the dosing in a conveying operation and to promote in a Rücksaugbetrieb reducing agent from the dosing into the reducing agent tank. Also, the lines that connect the dosing with the pumping device and the pumping device itself can be emptied. The apparatus also includes an electromagnetic switching valve that allows the operation of the apparatus to be switched between the conveying operation and the sucking-back operation, the electromagnetic switching valve having a magnetic armature according to an embodiment of the invention.
Die Erfindung stellt einen prozess- und kostenoptimierten Magnetanker zur Verfügung, der durch eine Korrosionsschutzschicht gegen Korrosion geschützt und durch eine Gleitschicht dauerhaft trockengeschmiert ist.The invention provides a process- and cost-optimized magnet armature which is protected against corrosion by a corrosion protection layer and permanently dry-lubricated by a sliding layer.
In einem Ausführungsbeispiel erfolgt das Aufbringen der Korrosionsschutzschicht durch Gas-Nitrocarburieren. Gas-Nitrocarburieren hat sich als ein vorteilhaftes Verfahren zum Ausbilden einer Korrosionsschutzschicht erwiesen.In one embodiment, the application of the corrosion protection layer by gas nitrocarburizing takes place. Gas nitrocarburizing has proven to be an advantageous method of forming a corrosion protection layer.
In einem Ausführungsbeispiel ist die Gleitschicht eine Kunststoff-Polymer-Schicht, insbesondere eine PTFE-Schicht mit eingelagertem Molybdändisulfid (MoS2). In einem Ausführungsbeispiel ist die Gleitschicht eine Polyamidimidschicht, insbesondere eine Polyamidimidschicht, die zusätzlich PTFE und/oder Molybdändisulfid enthält. Derartige Verbindungen stellen besonders haltbare Oberflächen mit einem geringen Reibungskoeffizienten zur Verfügung.In one embodiment, the sliding layer is a plastic-polymer layer, in particular a PTFE layer with embedded molybdenum disulfide (MoS 2 ). In one embodiment, the sliding layer is a polyamide-imide layer, in particular a polyamide-imide layer, which additionally PTFE and / or molybdenum disulfide contains. Such compounds provide particularly durable surfaces with a low coefficient of friction.
In einem Ausführungsbeispiel wird das Grundmaterial vor dem Aufbringen der Korrosionsschutzschicht nicht aufgeraut. Es ist insbesondere nicht notwendig, das Grundmaterial aufzurauen, da die Poren in der Korrosionsschutzschicht eine ausreichend große Oberfläche zur Verfügung stellen, an denen die Gleitschicht gut haftet. Auf den zusätzlichen Arbeitsschritt des Aufrauens der Oberfläche kann daher verzichtet werden.In one embodiment, the base material is not roughened prior to the application of the anti-corrosion layer. In particular, it is not necessary to roughen the base material because the pores in the anticorrosive layer provide a sufficiently large surface area to which the slip layer adheres well. The additional step of roughening the surface can therefore be dispensed with.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren näher erläutert.The invention will be explained in more detail below with reference to the attached figures.
