Abstract
Description
Die Erfindung betrifft eine Schmiervorrichtung für eine Steuerkette an einer Brennkraftmaschine zum Antrieb einer Nockenwelle von einer Kurbelwelle aus gemäß den weiteren im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen.The The invention relates to a lubricating device for a timing chain on a Internal combustion engine for driving a camshaft from a crankshaft out according to the others in the preamble of claim 1 specified characteristics.
Eine
gattungsgemäße Schmiervorrichtung ist
aus der
Durch die Anordnung der Spritzöldüse an dem Trägerteil können sich fertigungsbedingte Versetzungen zwischen den Spritzölöffnungen an der Spritzöldüse und der Laufebene der Steuerkette ergeben, so dass der Sprühstrahl nur zum Teil die Steuerkette erreicht. Die Folge davon ist eine ungenügende Schmierung der Steuerkette sowie die Erzeugung eines zusätzlichen unerwünschten Schmierölnebels, der die Ölabscheidung an der Ölzentrifuge der Kurbelgehäuseentlüftung zusätzlich erschwert.By the arrangement of the spray oil nozzle on the support part can Production-related dislocations between the spray oil openings at the spray oil nozzle and the Running plane of the timing chain yield, so that the spray only partially reached the timing chain. The result is one inadequate Lubricating the timing chain and generating an additional undesirable Oil mist that the oil separation at the oil centrifuge the crankcase ventilation additionally difficult.
Des
weiteren ist aus der
Da die Spritzöldüse unabhängig von der Gleitschiene am Motorgehäuse angeordnet ist, können auch hier fertigungsbedingte Versetzungen zwischen der Spritzöffnung in der Gleitschiene und dem Düsenloch in der Spritzöldüse auftreten, so dass nur ein Teil des Spitzölstrahls in die Schmierölnut der Gleitschiene gelangt, wodurch auch hier die Schmierung beeinträchtigt und ein unerwünschter Schmierölnebel erzeugt wird.There the spray oil nozzle independent of the slide rail on the motor housing is arranged here also production-related dislocations between the injection opening in the slide rail and the nozzle hole occur in the spray oil nozzle, leaving only part of the pointed oil jet in the lubricating oil groove the sliding rail passes, whereby also affects the lubrication and generates an undesirable lubricating oil mist becomes.
Schließlich sind
aus der
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Schmiervorrichtung derart weiter zu verbessern, dass ohne Beanspruchung von zusätzlichem Bauraum und ohne zusätzliche Montagemittel eine optimale Ausrichtung des Sprühölstrahles in Bezug auf die Laufebene der Steuerkette erzielt wird.Of the Invention is based on the object, the generic lubricating device to further improve that without claiming additional Space and without additional Mounting means an optimal alignment of the Sprühölstrahles in relation to the Running level of the timing chain is achieved.
Die Aufgabe ist erfindungsgemäß dadurch gelöst, dass die Ölspritzeinrichtung im Lagerbolzen der Gleitschiene integriert ist.The Task is inventively achieved in that the oil sprayer is integrated in the bearing pin of the slide rail.
Mit der erfindungsgemäßen Lösung wird erreicht, dass die Düsenöffnung der Spritzöleinrichtung innerhalb der Laufebene der Steuerkette liegt. Dadurch wird sichergestellt, dass der von der Spritzöldüse ausgehende Schmieröl-Sprühstrahl im wesentlich immer vollflächig auf die Kettenglieder der Steuerkette auftrifft. Hierdurch wird eine bestmögliche Schmierung der Steuerkette mit einer möglichst geringen Sprühnebelrate erzielt.With the solution according to the invention is achieved that the nozzle opening of the Spray oil device within the running plane of the timing chain is. This will ensure that outgoing from the spray oil nozzle Oil spray essentially always full surface impinges on the chain links of the timing chain. This will the best possible lubrication the timing chain with one possible low spray rate achieved.
Durch die Integration der Spritzöldüse in ein fertigungs- und toleranzmäßig von der Lage der Steuerkette abhängiges Bauele ment wird ferner erreicht, dass eine besondere Ausrichtung der Spritzöldüse in bezug auf die montierte Steuerkette nicht mehr erforderlich ist.By the integration of the spray oil nozzle into a production and tolerant of the position of the timing chain dependent It also achieves a specific orientation the spray oil nozzle with respect on the assembled timing chain is no longer required.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher beschrieben wird.In The drawing is an embodiment of the invention, which will be described in more detail below.
