Description

Die Erfindung bezieht sich auf eine Kühl- und Schmiermittelführung für Brennkraftmaschinen.The invention relates to a coolant and lubricant guide for internal combustion engines.

Bei Brennkraftmaschinen mit Wasserkühlung ist es üblich, sowohl das Kühlwasser, als auch das Schmieröl zunächst dem Kurbelgehäuse zuzuführen. Die Kühlwasser- und Schmierölversorgung für den Zylinderkopf wird über Durchtrittsbohrungen bewerkstelligt, welche Kurbelgehäuse und Zylinderkopf verbinden. Die Abdichtung der Durchtritte erfolgt mittels einer Metalldichtung und Dichtelemente (Elastomer) bzw. nichtmetallische Dichtung die ebenfalls mit Dichtelementen versehen ist, welche neben einer Brennraumdichtung erforderlich ist. Dies führt zu einer großen Anzahl von Dichtstellen die damit ein statistisch großes Potential für Ausfall darstellen.In internal combustion engines with water cooling, it is common for both the cooling water and also supply the lubricating oil to the crankcase first. The cooling water and Lube oil supply for the cylinder head is accomplished through through holes, which connect crankcase and cylinder head. Sealing the Entrances are made using a metal seal and sealing elements (elastomer) or non-metallic seal which is also provided with sealing elements, which next to a combustion chamber seal is required. This leads to a large number of Sealing points that represent a statistically great potential for failure.

Der Erfindung liegt daher die Aufgabe zugrunde, die Metalldichtung und Dichtelemente ( Elastomer) bzw. nichtmetallische Dichtung die ebenfalls mit Dichtelementen versehen ist für den Durchtritt von Schmieröl und Kühlwasser zwischen Kurbelgehäuse und Zylinderkopf vollständig zu vermeiden.The invention is therefore based on the object, the metal seal and sealing elements (Elastomer) or non-metallic seal which also with sealing elements is provided for the passage of lubricating oil and cooling water between the crankcase and to avoid the cylinder head completely.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of the patent claim 1 solved.

Dadurch, daß sowohl Schmieröl wie auch Kühlwasser mittels eines einteiligen Verteilerstück über die Stirnseiten von Kurbelgehäuse und Zylinderkopf zu, bzw. abgeführt wird vermeidet man jegliche Durchtrittsöffnungen zwischen Kurbelgehäuse und Zylinderkopf. Eine Weichdichtung ist nicht mehr notwendig. The fact that both lubricating oil and cooling water by means of a one-piece distributor via the end faces of the crankcase and cylinder head you avoid any openings between the crankcase and the cylinder head. A soft seal is no longer necessary.

Vorteilhafte Weiterbildungen der Erfindung können den Unteransprüchen 2 bis 5 entnommen werden.Advantageous developments of the invention can be found in subclaims 2 to 5 become.

Ein Ausführungsbeispiel der erfindungsgemäßen Kühl- und Schmiermittelführung ist in Zeichnungen dargestellt.An embodiment of the coolant and lubricant guide according to the invention is shown in drawings.

Fig. 1 zeigt in Seitenansicht eine Brennkraftmaschine 1 mit Kurbelgehäuse 2 und Zylinderkopf 3. An die Brennkraftmaschine 1 ist im Bereich einer Trennebene 4 zwischen Kurbelgehäuse 2 und Zylinderkopf 3 ein einteiliges Verteilerstück 5 angeflanscht. Das Verteilerstück 5 dient der Zu- bzw. Abfuhr von Kühlwasser und Schmieröl, wie unter Fig. 2 näher dargestellt. Das Kühlwasser und das Schmieröl wird erfindungsgemäß dem Kurbelgehäuse 2 und dem Zylinderkopf 3 separat über das Verteilerstück 5 zugeführt. Die Kühlwasserzufuhr erfolgt über Kühlwasserzu-laufkanäle 6a, 6b für das Kurbelgehäuse 2 und den Zylinderkopf 3, sowie die Schmierölzuführung über Ölzulaufbohrungen 7a, 7b für Kurbelgehäuse 2 und Zylinderkopf 3. Die Kühlwasserzulaufkanäle 6a, 6b und die Ölzulaufbohrungen 7a, 7b durchziehen achsparallel zu einer Kurbelwelle das Kurbelgehäuse 2 und den Zylinderkopf 3. Das Kühlwasser gelangt von den Kühlwasserzulaufkanälen 6a, 6b zu den Zylinderlaufbüchsen 8 und den Kühlflächen 9 im Zylinderkopf 3, wie in den Figuren 4 und 5 näher dargestellt.Fig. 1 shows a side view of an internal combustion engine 1 with a crankcase 2 and cylinder head 3.

The cooling water is supplied via cooling water supply channels 6a, 6b for the crankcase 2 and the cylinder head 3, as well as the lubricating oil supply via oil inlet bores 7a, 7b for crankcase 2 and cylinder head 3. Die Cooling water inlet ducts 6a, 6b and the oil inlet bores 7a, 7b run parallel to the axis to a crankshaft the crankcase 2 and the cylinder head 3. The cooling water passes from the cooling water inlet channels 6a, 6b to the cylinder liners 8 and the cooling surfaces 9 in the cylinder head 3, as shown in more detail in Figures 4 and 5.

Von den Ölzulaufbohrungen 7a, 7b zweigen Verteilerbohrungen ab, welche zu den Verbrauchern führen. Fig. 1 zeigt als Beispiel eine erste Verteilerbohrung 8a, welche von der Ölzulaufbohrung 7a im Kurbelgehäuse 2 abzweigt und zu einem Kurbelwellenlager 9 führt, während eine zweite Verteilerbohrung 8b die Ölzulaufbohrung 7b im Zylinderkopf 3 mit einem Nockenwellenlager 10 verbindet.From the oil inlet holes 7a, 7b branch off distributor holes, which to the Lead consumers. 1 shows an example of a first distributor bore 8a, which branches off from the oil inlet bore 7a in the crankcase 2 and to a crankshaft bearing 9 leads while a second distributor bore 8b in the oil inlet bore 7b Cylinder head 3 connects to a camshaft bearing 10.

Fig. 2 zeigt eine detaillierte Darstellung mi Bereich des Verteilerstuckes 5, welches stirnseitig an Kurbelgehäuse 2 und Zylinderkopf 3 angeflanscht ist. Über Bohrungen im Verteilerstuck 5 wird den Bohrungen 6a, 6b und 7a, 7b Wasser bzw. Öl zugeführt. Der Zylinderkopf 3 ist in der Trennebene 4 vom Kurbelgehäuse 2 getrennt. Vom Verteilerstück 5 ausgehend wird nun dem Kurbelgehäuse 2 und dem Zylinderkopf 3 getrennt Schmieröl und Kühlwasser zugeführt. 7a, 7b stellen wiederum die Ölzulaufbohrungen dar, während das Kühlwasser über die Kühlwasserzulaufkanäle 6a, 6b zugeführt wird. Die Abdichtung zwischen Zylinderkopf 3 und Kurbelgehäuse 2 einerseits und dem Verteilerstück 5 andererseits wird im dargestellten Beispiel von kurzen Rohrstücken 11 übernommen, welche O-Ringe 12a, 12b aufweisen. Die Rohrstücke 11 sind in Übergangsbohrungen 11a, 11b eingesteckt, welche zum Ausgleich von Toleranzen radiales Spiel aufweisen, hier zur Ölzulaufbohrung 7b.Fig. 2 shows a detailed representation mi area of the manifold 5, which is flanged to the front of crankcase 2 and cylinder head 3. About drilling In the distributor piece 5, the holes 6a, 6b and 7a, 7b are supplied with water or oil. The cylinder head 3 is separated from the crankcase 2 in the parting plane 4. From the distributor 5 starting from the crankcase 2 and the cylinder head 3 is now separated Lubricating oil and cooling water supplied. 7a, 7b in turn provide the oil inlet bores represents while the cooling water is supplied via the cooling water supply channels 6a, 6b becomes. The seal between the cylinder head 3 and crankcase 2 on the one hand and the distributor 5 on the other hand is short in the example shown Pipe pieces 11 taken over, which have O-rings 12a, 12b. The pipe sections 11 are inserted into transition bores 11a, 11b, which compensate for tolerances have radial play, here to the oil inlet bore 7b.

Anstelle der Rohrstücke 11 könnte auch eine hier nicht näher dargestellte Flachdichtung vorgesehen sein, welche zwischen Zylinderkopf 3 bzw. Kurbelgehäuse 2 und dem Verteilerstück 5 eingelegt wird. Die Flachdichtung muß dann mit Öffnungen versehen sein, um den Durchtritt von Schmieröl und Kühlwasser vom Verteilerstuck 5 zu Kurbelgehäuse 2 und Zylinderkopf 3 zu gewahrleisten. Die Stirnfläche 13 wird dann vorteilhafterweise etwas erhaben ausgeführt, um die Bearbeitung als Dichtfläche zu erleichtern.Instead of the pipe pieces 11, a flat seal, not shown here, could also be used be provided, which between the cylinder head 3 or crankcase 2 and the Distributor 5 is inserted. The flat gasket must then have openings be to the passage of lubricating oil and cooling water from the distributor 5 to the crankcase 2 and cylinder head 3 to ensure.
