DOLLAR A Zu diesem Zweck sind einzelne Bauteile mit speziellen Zentrierhilfen für ein exaktes Zusammenfügen versehen, wobei gleichzeitig zumindest einzelne der zusammenfügbaren Bauteile in fertig bearbeitetem Zustand zusammenfügbar sind.A control device for gas exchange valves of an internal combustion engine, with which different valve strokes can be generated, should be simple in terms of its individual components and should be able to be manufactured efficiently with high tolerance accuracy. DOLLAR A For this purpose, individual components are provided with special centering aids for an exact assembly, at the same time at least some of the components that can be assembled can be assembled in the finished state.
Description
Die Erfindung betrifft eine Steuereinrichtung für Gaswechselventile eines Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a control device for gas exchange valves an internal combustion engine according to the preamble of the claim 1.
Eine solche Einrichtung ist aus
Die Erfindung beschäftigt sich mit dem Problem, einen Aufbau der gattungsgemäßen Steuereinrichtung zu schaffen, bei dem durch einfache und rationell zu handhabende Fertigungsverfahren eine äußerst hohe funktionelle Betriebsgenauigkeit der Steuereinrichtung erreicht werden kann.The invention is concerned with the problem of creating a structure of the generic control device, in the manufacturing process that is simple and efficient to use an extremely high one functional operating accuracy of the control device achieved can be.
Gelöst wird dieses Problem durch die Ausgestaltung einer gattungsgemäßen Steuereinrichtung nach den kennzeichnenden Merkmalen des Patentanspruchs 1.This problem is solved by the design of a generic control device according to the characterizing features of claim 1.
Die Erfindung beruht auf dem allgemeinen Gedanken, die für einen Verbrennungsmotor mehreren Kulissen, die ein gemeinsames stabiles Bauteil bilden müssen, möglichst einfach und mit höchster Genauigkeit für einen toleranzarmen Einbau innerhalb der Steuereinrichtung rationell bearbeiten zu kön nen. Die ersten und zweiten Führungsbahnen an den Kulissen müssen, wenn die einzelnen Kulissen nicht aus bereits fertig bearbeiteten Einzelteilen zu einem Bauteil maßgerecht zusammensetzbar sind, an dem gemeinsamen Bauteil in einem letzten Bearbeitungsschritt geschliffen werden. Bei einem Mehrzylindermotor befinden sich zwischen den einzelnen Kulissen Bauelementabschnitte, mit denen die zu einem gemeinsamen Bauteil zusammengefassten Kulissen um eine Achse schwenkbar gelagert sind. Durch diese Bauabschnitte können die Führungsbahnen mehrerer nebeneinanderliegender Kulissen nicht mit einer die Kulissenbahnen nacheinander überfahrenden Schleifvorrichtung bearbeitet werden. Ein aufeinanderfolgendes Schleifen hintereinander in der Vorschubrichtung einer Schleifvorrichtung liegender Führungsbahnen wird bei den erfindungsgemäßen Ausführungen auf jeweils unterschiedliche Art gemeinsam dadurch erreicht, dass die einen solchen durchgehenden Schleifvorgang behindernden, zwischen den Kulissen liegenden Bauabschnitte als nachträglich an ein die bereits geschliffenen Kulissen enthaltendes Bauteil anbringbar gestaltet sind.The invention is based on the general idea the for an internal combustion engine multiple backdrops that have a common stable Must form a component, preferably simple and with the highest accuracy for one Rationally process low-tolerance installation within the control device to be able to. The first and second guideways on the scenes, if the individual backdrops are not already finished Individual parts can be assembled to form a component, on the common component in a last processing step be sanded. In a multi-cylinder engine are between the individual backdrops component sections with which the to a common Component-linked scenes pivoted about an axis are. Through these construction sections, the guideways of several side by side Backdrops not with one crossing the backdrop tracks one after the other Grinding device can be processed. A successive grinding one after the other in the feed direction of a grinding device horizontal guideways is in the embodiments of the invention achieved in different ways together in that that hinder such a continuous grinding process, between the sections lying behind the scenes as retrofitted to the ones that have already been sanded Components containing scenes are designed to be attachable.
Bei einer alternativen, besonders zweckmäßigen Ausgestaltung der Erfindung wird das die einzelnen Kulissen sowie die als Verbindung zu der Schwenkachse fungierenden Bauteilabschnitte enthaltende Gesamtbauteil aus fertig bearbeiteten Einzelelementen zusammengefügt. Bei diesen Einzelelementen handelt es sich um die Kulissen, die beispielsweise auf Fertigmaß gesintert oder gestanzt vorgefertigt sein können, einen fertig bearbeiteten Träger in insbesondere der Form einer Welle sowie Wangen zur Anlenkung an die Schwenkachse, wobei die Kulissen und die Wangen auf den Träger aufgeschoben und mit diesem jeweils durch einen Presssitz verbunden werden können. Bei dieser Art der Fertigung werden die vorgenannten einzelnen Teile maßgerecht gegeneinander ausgerichtet zu einem fertigen Gesamtbauteil gefügt.An alternative, especially appropriate design the invention is the individual backdrops as well as the connection overall component containing component sections functioning to the pivot axis assembled from finished individual elements. at These individual elements are the backdrops, for example sintered to finished size or can be pre-punched, in particular a finished carrier the shape of a shaft and cheeks for articulation on the swivel axis, whereby the backdrops and cheeks are pushed onto the carrier and with it can each be connected by a press fit. With this type of manufacturing the aforementioned individual parts are aligned against each other added to a finished overall component.
Zweckmäßige Ausgestaltungen für insbesondere diejenigen Ausführungsformen, bei denen die Kulissen nicht auf Endmaß vorgefertigt eingesetzt werden, das heißt bei denen die Kulissen in einem gemeinsamen Fertigbearbeitungsprozess geschliffen werden sollen, sind Gegenstand der Unteransprüche.Appropriate configurations for in particular those embodiments where the backdrops are not used to their final dimensions, this means where the scenes are in a common finishing process to be ground are the subject of the subclaims.
Vorteilhafte Ausgestaltungen der Erfindung sind in der Zeichnung dargestellt.Advantageous embodiments of the Invention are shown in the drawing.
