Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Gaswechselventils eines Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1 sowie ein nach diesem Verfahren hergestelltes Gaswechselventil.The invention relates to a method for producing a Gas exchange valve of an internal combustion engine according to the generic term of claim 1 and one according to this method manufactured gas exchange valve.

Gattungsgemäße Gaswechselventile sind in einer Ausbildung als sogenannte Leichtbauventile bekannt. Bei diesen bekannten Ventilen werden zunächst die Einzelteile, aus denen diese bestehen, miteinander verschweißt und sodann erfolgt eine Fertigbearbeitung und zwar insbesondere mit Bezug auf die Länge dieser Ventile. Derart hergestellte Leichtbauventile sind beispielsweise bekannt aus der Veröffentlichung 2000-01-0906 der Society of Automotive Engineers, Inc.: A New Concept For Steel-Composite Leightweight Valves" von Andreas von Kaenel, Peter Grahle und Marcus Abele der Mahle Ventiltrieb GmbH.Generic gas exchange valves are in training known as so-called lightweight valves. With these known Valves are first the individual parts that make up these exist, welded together and then there is a Finishing, especially with reference to the Length of these valves. Lightweight valves manufactured in this way are known for example from the publication 2000-01-0906 the Society of Automotive Engineers, Inc .: A New Concept For Steel-Composite Leightweight Valves "by Andreas by Kaenel, Peter Grahle and Marcus Abele der Mahle Ventiltrieb GmbH.

Die Erfindung beschäftigt sich mit dem Problem, die Herstellung solcher gattungsgemäßer Leichtbauventile zu vereinfachen, um hierdurch die erforderlichen Herstellungskosten zu senken.The invention deals with the problem of manufacturing to simplify such generic lightweight valves, to thereby increase the necessary manufacturing costs reduce.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Verfahren in erster Linie durch die Herstellungsschritte nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This task is solved in a generic method primarily through the manufacturing steps according to the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen dieses Verfahrens sind Gegenstand der Verfahrens-Unteransprüche.Advantageous embodiments of this method are the subject of the procedural subclaims.

Der auf ein nach dem erfindungsgemäßen Verfahren hergestelltes Gaswechselventil gerichtete letzte Anspruch zeigt eine besonders vorteilhafte Ausführung eines gattungsgemäßen Gaswechselventiles auf.The one made by the method according to the invention A gas exchange valve directed last claim shows one particularly advantageous embodiment of a generic gas exchange valve on.

Die Erfindung beruht in erster Linie auf dem allgemeinen Gedanken, ein gattungsgemäßes Leichtbauventil aus einzelnen Teilen paßgenau auf ein vorbestimmtes Längenmaß zu fügen und diese Teile in diesem Zustand miteinander zu verschweißen. Dabei sollen alle bzw. zumindest möglichst viele erforderlichen Bearbeitungen möglichst noch vor dem Fügen erfolgen können, so dass im Idealfall nach dem Fügen und Verschweißen bereits vollständig fertig bearbeiteter Einzelteile keine Nachbearbeitung mehr erfolgen muss.The invention is based primarily on the general idea a generic lightweight valve made up of individual Parts to fit exactly to a predetermined length and to weld these parts together in this state. All or at least as many as possible should be required Processing should be done before joining if possible can, so ideally after joining and welding already fully finished individual parts none Postprocessing needs to be done more.

Ein als Leichtbauventil ausgebildetes Gaswechselventil besteht aus einem hohlen Ventilteller 1, einem rohrförmigen Ventilschaft 2 sowie einem das dem Ventilteller 1 gegenüberliegende Ende des Ventilschaftes 2 verschließenden Druckstück 3. Der Ventilschaft 2 ist sowohl mit dem Ventilteller 1 als auch mit dem Druckstück 3 jeweils über einen Schiebesitz verbunden. Die Zuordnung zwischen dem Ventilteller 1 und dem Ventilschaft 2 ist dadurch gegeben, dass der Ventilschaft 2 axial auf Anschlag in dem Ventilteller 1 ausgerichtet ist. Bei dieser Ausrichtung erfolgt die Schweißverbindung zwischen Ventilteller 1 und Ventilschaft 2.There is a gas exchange valve designed as a lightweight valve from a hollow valve plate 1, a tubular Valve stem 2 and one opposite valve plate 1 End of the valve stem 2 closing pressure piece 3. The valve stem 2 is both with the valve plate 1 as well as with the pressure piece 3 each via a sliding seat connected. The assignment between the valve plate 1 and the valve stem 2 is given by the fact that the valve stem 2 axially aligned to the stop in the valve plate 1 is. With this orientation, the weld connection is made between valve disc 1 and valve stem 2.

Die Zuordnung des Druckstückes 3 zu dem Ventilschaft 2 innerhalb des betreffenden Schiebesitzes erfolgt durch eine auf die Fertiglänge des Gaswechselventiles passgenaue Ausrichtung, nach der die Schweißverbindung als letzter Bearbeitungsschritt erfolgt. Bei dieser Füge- und Verbindungstechnik ist es bei einem Einsatz vollständig fertig bearbeiteter Teile möglich, nach dem Verschweißen der einzelnen Teile keine Nachbearbeitung mehr vornehmen zu müssen. Aber auch, wenn noch einzelne, in den Unteransprüchen näher angegebene Nachbearbeitungen und Wärmebehandlungen erforderlich sind, entfällt in jedem Fall eine zerspanende Längenbearbeitung des Gaswechselventiles nach dessen Herstellung durch das erfindungsgemäße Fügen und Schweißen.The assignment of the pressure piece 3 to the valve stem 2 within of the relevant sliding seat is carried out by a precise alignment to the finished length of the gas exchange valve, after the welded joint as the last machining step he follows. With this joining and connection technology it is completely finished when used Parts possible after welding the individual Parts no longer have to do post-processing. But even if still individual, specified in the subclaims Reworking and heat treatment required cutting length machining is omitted in any case of the gas exchange valve after its manufacture joining and welding according to the invention.

Keine Nacharbeit ist insbesondere bei dem Widerlager 4 des Gaswechselventiles für die übliche Ventilfeder erforderlich, wenn dieses Widerlager in dem Druckstück 3 mit einem vorbestimmten Abstand zu dessen freiem Ende, das heißt dessen Anschlagfläche für eine Ventilbetätigungseinrichtung, lagegenau eingebracht ist, bevor das Druckstück 3 mit dem Ventilschaft längengenau verbunden wird.No rework is particularly the abutment 4 of the Gas exchange valves required for the usual valve spring, if this abutment in the pressure piece 3 with a predetermined Distance to its free end, i.e. its stop surface for a valve actuation device, precise position is introduced before the pressure piece 3 with the valve stem is precisely connected in length.

Das Widerlager 4 ist an dem Druckstück 3 als eine einfache Ringstufe ausgebildet. Da diese Ringstufe einen definierten Abstand zu dem freien Ende des Druckstückes 3 aufweist, besitzt dieses Widerlager 4 automatisch auch mit Bezug auf die Ventilfeder eine paßgenaue Lage. Eine zwischen dem Widerlager 4 und der nicht gezeichneten Ventilfeder für eine Montierbarkeit der Feder erforderliche Stützeinrichtung 5 kann in üblicher Weise aus einem äußeren Ring 6 sowie einem inneren, umfangsmäßig geteilten Ring 7 bestehen, wobei diese beiden Ringe über eine Konusfläche derart koaxial ineinanderliegen, dass sie sich unter dem Druck der Ventilfeder in dem Widerlager 4 paßgenau abstützen und fixieren können.The abutment 4 is on the pressure piece 3 as a simple one Ring step trained. Because this ring step has a defined one Has distance to the free end of the pressure piece 3 has this abutment 4 automatically with reference to the Valve spring in a precisely fitting position. One between the abutments 4 and the valve spring, not shown, for mounting the spring necessary support 5 can in the usual way from an outer ring 6 and an inner, circumferentially divided ring 7 exist, these the two rings lie coaxially one inside the other over a conical surface, that they are under the pressure of the valve spring support and fix the abutment 4.

Der Schiebesitz zwischen dem Druckstück 3 und dem rohrförmigen Schaft 2 ist derart ausgebildet, dass das Druckstück 3 mit einem längenmäßigen Teilbereich in das Innere des Schaftes 2 eingreift, wobei zur Einstellung eines paßgenauen Längenmaßes des Gaswechselventiles das Druckstück 3 innerhalb des Schaftes 2 axial verschiebbar ist. Das Verschweißen zwischen Druckstück 3 und Schaft 2 erfolgt bei paßgenau eingestellter Gesamtlänge des Gaswechselventiles.The sliding seat between the pressure piece 3 and the tubular Shaft 2 is designed such that the pressure piece 3 with a partial length section into the interior of the shaft 2 engages, for setting a precisely fitting length of the gas exchange valve the pressure piece 3 within of the shaft 2 is axially displaceable. The welding between Pressure piece 3 and shaft 2 takes place with a precisely adjusted Total length of the gas exchange valve.

Der Ventilteller 1 kann auch aus Vollmaterial, beispielsweise Leichtmetall oder Keramik bestehen oder aus mehreren Blechteilen zusammengesetzt sein.The valve disk 1 can also be made of solid material, for example Light metal or ceramic consist or several Be sheet metal parts assembled.

Besonders vorteilhaft wird dabei der Ventilschaft 2 mit einerseits dem brennraumseitigen und andererseits dem druckstückseitigen Ende des Ventiltellers 1 verbunden, um die Steifigkeit des Ventiltellers zu verbessern.The valve stem 2 with one hand is particularly advantageous the combustion chamber side and on the other hand the pressure piece side End of the valve plate 1 connected to the To improve the rigidity of the valve plate.
