Description

Die Erfindung betrifft ein Maschinengehäuse, insbesondere einen Zylinderkopf für eine Brennkraftmaschine, mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a machine housing, in particular a cylinder head for an internal combustion engine, with the features of the preamble of patent claim 1.

Sie geht von der europäischen Patentanmeldung EP 1 350 928 A2 aus. In dieser ist eine Vorrichtung zur variablen Betätigung eines Hubventils einer Brennkraftmaschine beschrieben. Diese Vorrichtung ist in einem Maschinengehäuse angeordnet, und besteht neben weiteren Bauteilen zumindest aus einer Nockenwelle und einer zur Nockenwelle parallel angeordneten weiteren Welle, einer Exzenterwelle zur Hubhöhenverstellung des Hubventils. Die Nockenwelle und die Exzenterwelle sind jeweils drehbar in dem Maschinengehäuse gelagert. Ein Schlepphebel, der zur Betätigung eines Hubventils vorgesehen ist, ist einerseits auf einem Hydrosockel, einem hydraulischen Spielausgleichselement und andererseits auf dem Ventilschaft eines Hubventils gelagert. Der Hydrosockel wird wie auch die Lagerstellen von Nockenwelle und Exzenterwelle von einem unter Druck stehenden Schmiermittel versorgt.It is based on the European patent application EP 1 350 928 A2. In this a device for variable actuation of a lift valve of an internal combustion engine is described. This device is arranged in a machine housing, and consists in addition to other components at least a camshaft and a camshaft arranged in parallel to another shaft, an eccentric shaft for lifting height adjustment of the lift valve. The camshaft and the eccentric shaft are each rotatably mounted in the machine housing. A drag lever, which is provided for actuating a lift valve, is mounted on the one hand on a hydraulic base, a hydraulic clearance compensation element and on the other hand on the valve stem of a lift valve. The hydraulic base is supplied by a pressurized lubricant as well as the bearings of the camshaft and eccentric shaft.

Nachteilig bei der beschriebenen Ausgestaltung ist der hohe bauliche Aufwand, um alle Lagerstellen mit Schmiermittel zu versorgen. Wie dem Fachmann allgemein geläufig ist, erfolgt dies normalerweise über Schmiermittelspritzdüsen oder durch Schmiermittelbohrungen, die in den Lagerstellen enden.A disadvantage of the described embodiment, the high structural complexity to supply all bearings with lubricant. As is well known to those skilled in the art, this is usually done via lubricant spray nozzles or through lubricant bores terminating in the bearings.

Aufgabe der vorliegenden Erfindung ist es, eine vereinfachte Schmiermittelversorgung für die Lagerstellen eines gattungsgemäßen Maschinengehäuses aufzuzeigen.Object of the present invention is to show a simplified lubricant supply for the bearings of a generic machine housing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Maschinengehäuse eine Wandung aufweist, die in Einbaulage des Maschinengehäuses aus einem Lager ausgetretenes und/oder in dem Maschinengehäuse verspritztes Schmiermittel auffängt, wobei ein weiteres Lager zumindest abschnittsweise in dem aufgefangenen Schmiermittel angeordnet ist. Durch die vorgeschlagene Ausgestaltung werden die Fertigungskosten für ein gattungsgemäßes Maschinengehäuse reduziert, da die Bearbeitung von Schmiermittelbohrungen oder die Verwendung von zusätzlichen Schmiermittelspritzdüsen entfällt. Ferner weist das erfindungsgemäße Maschinengehäuse einen reduzierten Schmiermittelförderbedarf auf, wodurch eine kleinere Schmiermittelpumpe verwendet werden kann. Dies führt ebenfalls zu geringeren Herstellungskosten, sowie zu einem reduzierten Kraftstoffverbrauch der Brennkraftmaschine.This object is achieved in that the machine housing has a wall that emerges in the installed position of the machine housing from a bearing and / or spilled lubricant in the machine housing, wherein another bearing is at least partially disposed in the collected lubricant. The proposed embodiment, the manufacturing costs for a generic machine housing are reduced because the processing of lubricant holes or the use of additional lubricant spray nozzles deleted. Furthermore, the machine housing according to the invention has a reduced lubricant delivery requirement, whereby a smaller lubricant pump can be used. This also leads to lower production costs, and to a reduced fuel consumption of the internal combustion engine.

Die erfindungsgemäße Ausgestaltung eignet sich gemäß Patentanspruch 2 insbesondere für weitgehend parallel zur Nockenwelle angeordnete Wellen. Für diesen Fall kann beispielsweise wasserfallartig das aus dem Lager der Nockenwelle austretende Schmiermittel in der geodätisch tiefer gelegenen Mulde aufgefangen werden. Zusätzlich wird auch ein Teil des beim Betrieb der Brennkraftmaschine beispielsweise von den Nocken der Nockenwelle verspritztes Schmiermittel in der Mulde aufgefangen.The embodiment of the invention is suitable in particular for largely parallel to the camshaft arranged waves according to claim 2. For this case, for example, the water emerging from the bearing of the camshaft lubricant can be collected in the geodetically lower trough. In addition, a part of the lubricant splashed during operation of the internal combustion engine, for example, by the cam of the camshaft in the trough is collected.

Die vorgeschlagene Ausgestaltung ist insbesondere für hubvariable Ventiltriebe mit einer Hubhöhenverstellung durch eine Exzenterwelle geeignet.The proposed embodiment is particularly suitable for variable stroke valve trains with a stroke height adjustment by an eccentric shaft.

Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in zwei Figuren näher erläutert.

Fig. 1
zeigt eine Aufsicht auf ein erfindungsgemäßes Maschinengehäuse mit einer Nockenwelle und einer weiteren Welle,
Fig. 2
zeigt eine Aufsicht auf das erfindungsgemäße Maschinengehäuse ohne Nockenwelle und ohne weitere Welle.
In the following the invention with reference to a preferred embodiment is explained in more detail in two figures.
Fig. 1
shows a plan view of an inventive engine housing with a camshaft and another shaft,
Fig. 2
shows a plan view of the machine housing according to the invention without a camshaft and without another shaft.

Fig. 1 zeigt die Aufsicht auf ein dreidimensional dargestelltes Maschinengehäuse 1 mit einer Nockenwelle 2, im vorliegenden Fall ein Zylinderkopf für eine Brennkraftmaschine. Der Blick ist auf eine Teilungsebene 1' von einem in Fig. 2 erkennbaren Lager 3 einer weiteren Welle 4 gerichtet. Die weitere Welle 4 weist an ihrem Außenumfang ein Zahnradsegment 4' mit einer Außenverzahnung 4" auf. Dieses Zahnradsegment 4' dient beim Betrieb der Brennkraftmaschine zur Verdrehung der weiteren Welle 4, in der vorliegenden Ausführung eine Exzenterwelle, mittels einem nicht dargestellten Schneckenrad. Das Zahnradsegment 4' ist abschnittsweise in einer geodätisch tieferen Mulde 6 angeordnet und ragt bis in ein in der Mulde 6 gesammeltes Schmiermittel. Die Mulde 6 wird von drei Außenwänden 1" des Maschinengehäuses 1 gebildet, sowie einer erfindungsgemäß in Einbaulage weitgehend senkrecht ausgerichteten Wandung 5, die sich in dem Ausführungsbeispiel zwischen zwei Außenwänden 1" erstreckt, dargestellt durch einen Doppelpfeil. Neben dem Zahnradsegment 4' ist auch ein Teil des Lagers 3 im dem in der Mulde 6 gesammelten Schmiermittel angeordnet.Fig. 1 shows the top view of a three-dimensionally illustrated engine housing 1 with a camshaft 2, in the present case, a cylinder head for an internal combustion engine. The view is directed to a dividing plane 1 'of a recognizable in Fig. 2 bearing 3 another shaft 4. The further shaft 4 has on its outer circumference a gear segment 4 'with an outer toothing 4 ". This gear segment 4' serves to rotate the further shaft 4 during operation of the internal combustion engine, in the present embodiment an eccentric shaft, by means of a worm wheel (not shown) 4 'is arranged in sections in a geodetically deeper depression 6 and protrudes into a lubricant collected in the depression 6. The depression 6 is formed by three outer walls 1 "of the machine housing 1 and a wall 5 which according to the invention is oriented largely vertically in the installed position in the embodiment between two outer walls 1 "extends, represented by a double arrow .. In addition to the gear segment 4 'and a part of the bearing 3 is arranged in the collected in the trough 6 lubricant.

Beim Betrieb der Brennkraftmaschine wird die Mulde 6 im vorliegenden Ausführungsbeispiel durch von dem Ventiltrieb und Schmiermittelspritzdüsen verspritztes Schmiermittel aufgefüllt. In einem weiteren Ausführungsbeispiel kann auch ein weiteres Lager geodätisch oberhalb der Mulde 6 angeordnet sein, wobei in diesem Fall die Mulde 6 von aus diesem Lager austretendem Schmiermittel und je nach konstruktiver Ausgestaltung zusätzlich von verspritztem Schmiermittel aufgefüllt wird.During operation of the internal combustion engine, the depression 6 in the present embodiment is filled up with lubricant sprayed by the valve drive and lubricant injection nozzles. In another embodiment, a further bearing can be arranged geodetically above the trough 6, in which case the trough 6 is additionally filled with lubricating lubricant exiting from this bearing and, depending on the structural design.

Im vorliegenden Ausführungsbeispiel ist die weitere Welle 4, wie bereits oben kurz bemerkt, eine Exzenterwelle für einen hubvariablen Ventiltrieb, wobei die weitere Welle 4 parallel zur Nockenwelle 2 angeordnet ist. Selbstverständlich können auch noch weitere im Maschinengehäuse 1 angeordnete Lagerstellen von Wellen oder bewegte Bauteile auf die erfindungsgemäße Art und Weise geschmiert werden. In weiteren Ausführungsformen kann die Wandung 5 auch becherförmig, freistehend auf einer Bodenfläche des Maschinengehäuses 1 angeformt sein, ohne einen direkten Kontakt zu den Seitenwänden 1' aufzuweisen. In diesem Fall ist wird die Mulde 6 nur von der Wandung 5 und der Bodenfläche des Maschinengehäuses gebildet.In the present embodiment, the further shaft 4, as already briefly noted above, an eccentric shaft for a variable-stroke valve drive, wherein the further shaft 4 is arranged parallel to the camshaft 2. Of course, even more arranged in the machine housing 1 bearings of waves or moving components can be lubricated in the manner of the invention. In further embodiments, the wall 5 may also be cup-shaped, free-standing formed on a bottom surface of the machine housing 1, without having a direct contact with the side walls 1 '. In this case, the trough 6 is formed only by the wall 5 and the bottom surface of the machine housing.

Fig. 2 zeigt den gleichen Aufbau von Fig. 1, jedoch ohne Nockenwelle 2 und ohne weitere Welle 4. Für gleiche Bauteile gelten die gleichen Bezugsziffern.Fig. 2 shows the same structure of Fig. 1, but without camshaft 2 and without further shaft 4. For the same components apply the same reference numerals.

Aufgrund der erfindungsgemäßen Ausgestaltung werden die Herstell- bzw. Fertigungskosten für ein gattungsgemäßes Maschinengehäuse reduziert, da keine Schmiermittelbohrungen bzw. separate Schmiermittelspritzdüsen für das Lager 3 und/oder die Außenverzahnung 4" notwendig sind. Auch wird der Schmiermittelbedarf des Maschinengehäuses 1 deutlich reduziert, wodurch die Schmiermittelpumpe baulich verkleinert werden kann. Hierdurch sind Kosteneinsparpotentiale realisiert. Ferner ist der Energiebedarf einer kleineren Schmiermittelpumpe geringer, wodurch der Kraftstoffverbrauch beim Betrieb der Brennkraftmaschine reduziert ist.Owing to the embodiment according to the invention, the manufacturing or manufacturing costs for a generic machine housing are reduced, since no lubricant bores or separate lubricant spray nozzles are necessary for the bearing 3 and / or the external teeth 4 " In addition, the energy requirement of a smaller lubricant pump is lower, which reduces fuel consumption is reduced during operation of the internal combustion engine.
