Ein derartiger Lagerstuhl ist z.B. aus DE 29609950-U1 bekannt. Der Vorteil für die Verwendung eines Lagerstuhls liegt grundsätzlich in der erleichterten Montierbarkeit aufgrund Modulbauweise und in einer wesentlichen Versteifung des dem Brennraum gegenüberliegenden Endes des Motors. Bei dem aus dem Stand der Technik bekannten Lagerstuhl sind die Lagerdeckel für die Kurbelwelle mittels beidseitig des Kurbelwellenlagers vorgesehenen Lagerdeckelschrauben auf der dem Zylinderblock zugewandten Seite des Lagerstuhls angebracht. An dem Lagerstuhl ist ferner eine außenliegende am Lagerstuhl integrierte Ölgalerie angeordnet. Von der Ölgalerie ausgehend sind im Lagerstuhl verlaufende Lagerstuhl-Ölbohrungen vorgesehen, die zu im Lagerdeckel verlaufenden Ölbohrungen führen. Auf diese Weise kann das Öl der im Lagerdeckel befindlichen Hälfte des Kurbelwellenlagers zugeführt werden. Allerdings liegt hier die Austrittsöffnung der Lagerdeckel-Ölbohrung relativ nahe an der zwischen Lagerdeckel und Lagerstuhl verlaufenden Lagerdeckelanlagefläche.Such a storage chair is e.g. known from DE 29609950-U1. The advantage for them The use of a storage chair is basically easier to assemble due to the modular design and a substantial stiffening of the combustion chamber opposite end of the engine. In the known from the prior art Bearings are the bearing caps for the crankshaft on both sides of the Crankshaft bearing bearing bolts on the cylinder block facing side of the camp chair attached. On the camp chair is also a external oil gallery integrated in the storage chair. From the oil gallery proceeding in the bearing chair are running bearing oil holes that are provided drill oil holes in the bearing cap.

Aufgabe der Erfindung war es, bei einem Lagerstuhl mit zylinderblockseitig montierten
Lagerdeckeln die Ölversorgung des Kurbelwellenlagers zu verbessern. Diese Aufgabe
wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object of the invention was to mount on a cylinder block with a cylinder block
Bearing caps to improve the oil supply to the crankshaft bearing. This task
is solved by the characterizing features of
Gegenüber dem Stand der Technik ist die Ölgalerie innen im Lagerstuhl auf der von den Lagerdeckeln abgewandten Seite und diesen etwa gegenüberliegend angeordnet. Dies hat den Vorteil, dass eine wesentlich größere Freiheit hinsichtlich der Anordnung der Lagerstuhl-Ölbohrung, welche die Ölgalerie mit der Lagerdeckel-Ölbohrung verbindet, besteht. Damit kann auch die Lagerdeckel-Ölbohrung entsprechend den Erfordernissen der Lagerschmierung - in ihrer Lage lediglich begrenzt durch die Lagerdeckel-geometrie - optimiert gewählt werden. Compared to the state of the art, the oil gallery in the inside of the storage chair is that of the Bearing caps facing away from and arranged approximately opposite. This has the advantage that a much greater freedom with regard to the arrangement of the Bearing seat oil hole, which connects the oil gallery with the bearing cap oil hole, consists. This means that the bearing cap oil bore can also meet the requirements the bearing lubrication - its position is only limited by the bearing cap geometry - be chosen optimized.
Bevorzugt ist die Ölgalerie fluchtend unter den Lagerdeckelanlageflächen, die zwischen Lagerdeckel und Lagerstuhl verlaufen, angeordnet. Hierdurch wird die Fertigung wesentlich vereinfacht, weil die Lagerstuhl-Ölbohrung parallel zu der die Lagerdeckelschrauben aufnehmenden Bohrung ausgeführt werden kann. Insbesondere ist die Lagerstuhl-Ölbohrung zwischen Kurbelwellenlager und Lagerdeckelschraube vorgesehen, wobei die Lagerstuhl-Ölbohrung durch die Lagerdeckelanlagefläche hindurchgeht. Die Lagerstuhl-Ölbohrung kann hierdurch bevorzugt axial (in Kurbelwellenachse) versetzt zur Ebene durch die Lagerdeckelschraubenachsen angeordnet werden. Dadurch kann ein ununterbrochener Kraftfluß im Lagerdeckel erreicht werden.The oil gallery is preferably aligned under the bearing cap contact surfaces, which between Bearing cover and storage chair run, arranged. This is the manufacturing significantly simplified because the bearing bracket oil bore parallel to that of the Bearing cap screw receiving bore can be performed. In particular is the bearing bracket oil hole between the crankshaft bearing and the bearing cap screw provided, the bearing block oil hole through the bearing cap contact surface passes. As a result, the bearing block oil bore can preferably be axially (in Crankshaft axis) offset to the plane through the bearing cap screw axes to be ordered. This allows an uninterrupted flow of force in the bearing cap can be achieved.
Insbesondere verläuft die Ölgalerie fluchtend unter den in Kurbelwellendrehrichtung liegenden Lagerdeckelanlageflächen. Hierdurch wird in Kombination mit dem vorhergehenden Merkmalen erreicht, dass in Verbindung mit einer entsprechend angeordneten Lagerdeckel-Ölbohrung das Öl an einem Punkt der Kurbelwelle zugeführt wird, der noch oberhalb der unteren, im Lagerstuhl befindlichen, Hälfte des Kurbelwellenlagers liegt und erst mit der Drehung der Kurbelwelle in diese untere Lagerhälfte hineindreht.In particular, the oil gallery runs in alignment with those in the crankshaft direction of rotation horizontal bearing cap contact surfaces. This, in combination with the previous features achieved in conjunction with a corresponding arranged bearing cap oil hole, the oil at a point of the crankshaft will, which is still above the lower half of the Crankshaft bearing is and only with the rotation of the crankshaft in this lower Half of the bearing.
Nach einer weiter bevorzugten Ausführung wird die Lagerstuhl-Ölbohrung wenigstens teilweise durch eine die Lagerdeckelschrauben aufnehmende Bohrung gebildet. Hierdurch können die notwendigen Fertigungsoperationen weiter optimiert werden. Insbesondere kann in Verbindung mit entsprechenden Überströmräumen an der Lagerdeckelschraube selbst oder an deren Bohrung die Verbindung zwischen Lagerdeckel-Ölbohrung und Lagerstuhl-Ölbohrung hergestellt werden.According to a further preferred embodiment, the bearing block oil hole is at least partially formed by a bore receiving the bearing cap screws. This enables the necessary manufacturing operations to be further optimized. In particular, in connection with corresponding overflow spaces on the Bearing cap screw itself or at its bore the connection between Bearing cap oil hole and bearing block oil hole are produced.

Durch diese Ausführung werden die am Lagerstuhl notwendigen Bearbeitungsvorgänge weiter reduziert. Insbesondere kann die Ölgalerie so angeordnet werden, dass mit der Herstellung der Bohrung für die Lagerdeckelschrauben die Überströmöffnung von der Ölgalerie zur Lägerdeckelschraubenbohrung erstellt wird. In dem Fall bildet die Ölgalerie, bzw. die Bohrung für die Lagerdeckelschrauben, selbst die Lagerstuhl-Ölbohrung. Als weiteres braucht dann lediglich noch die Lagerdeckel-Ölbohrung erstellt werden.According to a further preferred embodiment, those are located near the oil gallery Bearing cap screws are at least partially hollow, this cavity over Bores in the bearing cap screw with the bearing cap screws receiving bore is connected and this on the one hand with the oil gallery, on the other hand is connected to the respective bearing cap oil hole. Through this Execution the necessary machining operations on the storage chair reduced. In particular, the oil gallery can be arranged so that with the Drilling the hole for the bearing cap screws the overflow opening from the Oil gallery for the bearing cap screw hole is created. In that case, the Oil gallery, or the hole for the bearing cap screws, even the bearing bracket oil hole. Then all that is needed is the bearing cap oil hole to be created.
In einer hierzu weiter bevorzugten Ausführung führt eine der Bohrungen in der Lagerdeckelschraube durch die dem Schraubenkopf entgegengesetzte Endfläche und axial zur Lagerdeckelschraube sowie koaxial zu der die Lagerdeckelschraube aufnehmenden Bohrung und mündet am schraubenkopfnahen Ende der Lagerdeckelschraube in eine Querbohrung, die mit der Lagerdeckel-Ölbohrung fluchtet. Hierdurch werden auch die an der Lagerdeckelschraube notwendigen Bearbeitungsvorgänge weiter minimiert. Insbesondere kann die Ölgalerie unmittelbar am unteren Ende der die Lagerdeckelschrauben aufnehmenden Bohrung angeordnet sein, so dass die Ölgalerie selbst bzw. die Lagerdeckelschraubenbohrung die Lagerstuhl-Ölbohrung bilden.In a further preferred embodiment, one of the bores in FIG Bearing cap screw through the end face opposite the screw head and axially to the bearing cap screw and coaxially to the bearing cap screw receiving bore and opens at the screw head near the end of the Bearing cap screw in a cross hole that is aligned with the bearing cap oil hole. This also makes the necessary on the bearing cap screw Processing operations further minimized. In particular, the oil gallery can be immediate arranged at the lower end of the bore receiving the bearing cap screws be so that the oil gallery itself or the bearing cap screw hole Form the bearing bracket oil hole.
Ausführungen der Erfindung für das Beispiel einer Brennkraftmaschine in Reihenanordnung werden anhand der schematischen Abbildungen (Fig. 1, 2) erläutert.Embodiments of the invention for the example of an internal combustion engine in Series arrangement are explained using the schematic illustrations (Fig. 1, 2).
Die Fig. 1 and 2 zeigen schematisch einen Schnitt, der etwa durch die Achsen der Lagerdeckelbefestigungsschrauben verläuft.1 and 2 show schematically a section which is approximately through the axes of the Bearing cap fastening screws runs.
Die Brennkraftmaschine 1 besteht in bekannter Weise aus einem Lagerstuhl 2, dem
Zylinderblock 3 und dem Zylinderkopf 4. Ölwanne sowie Zylinderkopfabdeckung sind
ebenfalls nur schematisch ausgeführt. Auf dem Lagerstuhl 2 sind Lagerdeckel 5 mittels
Lagerdeckelbefestigungsschrauben 51 aufgeschraubt. Zwischen Lagerstuhl 2 und den
Lagerdeckeln 5 sind die Bohrungen 52 für die Kurbelwellenlager (Hauptlager)
vorgesehen. In etwa die untere Hälfte der Lagerbohrung 52 ist also im Lagerstuhl,
während die obere Hälfte im Lagerdeckel angebracht ist. Zwischen Lagerstuhl 2 und
Lagerdeckel 5 sind die Lagerdeckelanlageflächen 53 ausgebildet. Dabei kann es sich um
gefräste Flächen oder - bei während der Herstellung des Lagerstuhls angegossenen
Lagerdeckeln - um Bruchflächen handeln. Ausgehend von der Bohrung für
Kurbelwellenlager 52 sind die Lagerdeckelbefestigungsschrauben 51 etwa symmetrisch
zu der Bohrung angeordnet. Die Verbindung zwischen Zylinderblock 3 und Lagerstuhl
2 erfolgt mittels Befestigungsschrauben 6 (Zylinderblockbefestigungsschrauben), die
bevorzugt durch die Bohrungen im Lagerstuhl und im Zylinderblock sowie im
Zylinderkopf bis in diesen hineinreichen. Am Lagerstuhl 2 ist zum Zylinderblock 3 hin
eine Dichtfläche 54 zur Montage des Lagerstuhls am Zylinderblock vorgesehen. Diese
Dichtfläche 54 erstreckt sich von der Außenwand 55 des Lagerstuhls in Richtung der
Bohrung 52 für das Kurbelwellenlager etwa senkrecht zu den
Zylinderblockbefestigungsschrauben bevorzugt bis über die diese aufnehmenden
Bohrungen. Innen am Lagerstuhl etwa fluchtend unter dem Lagerdeckel ist eine
Ölgalerie 7 angeordnet. Die Ölgalerie 7 verläuft mit ihrer Achse etwa parallel zur Achse
der Kurbelwelle 52. Von der Ölgalerie 7 ausgehend ist eine Lagerstuhl-Ölbohrung 72
vorgesehen, die hier etwa parallel zur Achse der Lagerdeckelschrauben verläuft und in
die Lagerdeckelanlagefläche 53 mündet. Fluchtend zur Lagerstuhlbohrung 72 ist eine
Lagerdeckelbohrung 71' vorgesehen, die mit einer etwa quer verlaufenden
Lagerdeckelbohrung 71 verbunden ist. Die Lagerdeckelbohrung 71 mündet in die
Lagerdeckelauflagefläche, die auf der Seite des Lagerdeckels in Drehrichtung (durch
den Pfeil angedeutet) liegt. Hierdurch wird das Öl an einem Punkt der Kurbelwelle
zugeführt, der sich oberhalb der unteren im Lagerstuhl liegenden Lagerhälfte befindet.
Durch die im Konstruktionsbeispiel dargestellte Ausführungsform kann die
Lagerstuhlbohrung auch axial versetzt zu der hier gewählten Schnittebene angeordnet
werden. Insbesondere können auch mehrere Lagerdeckel- bzw. Lagerstuhl-Ölbohrungen
angebracht werden.The
Bei dem in Figur 2 dargestellten Ausführungsbeispiel (die in Figur 1 verwendeten
Bezeichnungen gelten weiter) ist eine der Lagerdeckelschrauben 51 teilweise hohl
ausgeführt. Der Hohlraum besteht hier aus einer im wesentlichen axial zur
Lagerdeckelschraube verlaufenden Bohrung 74, die durch das dem Schraubenkopf
entgegenliegende Ende hindurchtritt. Zwei quer dazu verlaufende Bohrungen 73
münden in einen Ringraum 75, der mit der Lagerdeckel-Ölbohrung 71 in Verbindung
steht. Die beiden Querbohrungen 73 sind hier vorgesehen um einerseits eine
ausreichende Durchflussöffnung zu gewährleisten, andererseits den Tragquerschnitt der
Lagerdeckelschraube nicht zu sehr zu schwächen. Die im Lagerstuhl angebrachte
Bohrung für die Lagerdeckelschraube 71 mündet direkt oder indirekt (über eine
Lagerstuhl-Ölbohrung 72) in die Ölgalerie 7. Bei direkter Verbindung zwischen der
Ölgalerie 7 und der die Lagerdeckelschraube aufnehmenden Bohrung bildet letztere
selbst die Lagerstuhl-Ölbohrung 72. Die Ölgalerie 7 kann statt direkt fluchtend mit der
Lagerdeckelschraubenachse bzw. der sie aufnehmenden Bohrung auch seitlich versetzt
