Description

Brennkraftmaschine mit einem Zylinderkurbelgehäuse und einer v-förmigen Internal combustion engine with a cylinder crankcase and a V-shaped
Zylinderanordnungcylinder arrangement
Die Erfindung betrifft eine Brennkraftmaschine mit einem Zylinderkurbelgehäuse und einer v-förmigen Zylinderanordnung gemäß dem Oberbegriff des Patentan- spruchs 1.The invention relates to an internal combustion engine with a cylinder crankcase and a V-shaped cylinder arrangement according to the preamble of patent claim 1.
Brennkraftmaschinen mit einem Schmiermittelkreislauf nach dem Trockensumpfprinzip weisen einen separaten Schmiermittelsammelbehälter auf, in den das Schmiermittel mittels einer Schmiermittelpumpe aus einem kleinen Sammelraum unterhalb der Kurbelwelle gepumpt, und aus dem das Schmiermittel an die Schmierstellen der Brennkraftmaschine gefördert wird. Ein derartiger Schmiermittelkreislauf ist beispielsweise in der Druckschrift DE 36 20 480 beschrieben.Internal combustion engines with a lubricant circuit according to the dry sump principle have a separate lubricant reservoir into which the lubricant is pumped by means of a lubricant pump from a small reservoir below the crankshaft, and from which the lubricant is conveyed to the lubrication points of the internal combustion engine. Such a lubricant circuit is described for example in the document DE 36 20 480.
Einer der wesentlichen Vorteile der Trockensumpfschmierung besteht in dem nicht unterhalb der Kurbelwelle angeordneten Schmiermittelsammelbehälter, wodurch die Brennkraftmaschine einen tieferen Schwerpunkt aufweist, und wo- durch die Brennkraftmaschine in der Höhe weniger Bauraum benötigt.One of the major advantages of dry sump lubrication is the lubricant reservoir not disposed below the crankshaft, whereby the internal combustion engine has a lower center of gravity and thus the internal combustion engine requires less installation space.
Nachteilig ist dabei jedoch, dass in dem Motorraum eines Kraftfahrzeuges der Bauraum für die Anordnung und die Verschlauchung des separaten Schmiermittelsammelbehälters bereitgestellt werden muss.The disadvantage here, however, that in the engine compartment of a motor vehicle, the space for the arrangement and the tubing of the separate lubricant collection container must be provided.
Der Erfindung liegt die Aufgabe zugrunde einen Brennkraftmaschine mit einem Schmiermittelkreislauf nach dem Trockensumpfprinzip gemäß dem Oberbegriff des Patentanspruchs 1 anzugeben, bei dem der Schmiermittelsammelbehälter wenig Bauraum benötigt und dabei sehr kostengünstig hergestellt werden kann. Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichen des Patentanspruchs 1 gelöst, wonach der Schmiermittelsammelbehälter innerhalb des Zylinderkurbelgehäuses im Bauraum zwischen den Zylindern, bzw. den Zylinderreihen der Brennkraftmaschine, im so genannten Innen- v oder dem so genannten v-Raum, angeordnet ist.The invention has for its object to provide an internal combustion engine with a lubricant circuit according to the dry sump principle according to the preamble of claim 1, wherein the lubricant reservoir requires little space and can be produced very inexpensively. This object is achieved by the features in the characterizing part of patent claim 1, according to which the lubricant reservoir within the cylinder crankcase in the space between the cylinders, or the rows of cylinders of the internal combustion engine, in the so-called interior v or the so-called v-space is arranged.
Dabei werden die Wandungen des Schmiermittelsammelbehälters vollständig von dem Zylinderkurbelgehäuse gebildet und entstehen direkt beim Gießen des Zylinderkurbelgehäuses.The walls of the lubricant reservoir are completely formed by the cylinder crankcase and arise directly during the casting of the cylinder crankcase.
In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Schmiermittelkreislauf mindestens eine Schmiermittelpumpe aufweist, die innerhalb des Schmiermittelsammelbehälters angeordnet ist.In an advantageous development of the invention, it is provided that the lubricant circuit has at least one lubricant pump, which is arranged within the lubricant collecting container.
Dabei werden zumindest Teile des Gehäuses der Schmiermittelpumpe ebenfalls von der Wandung des Schmiermittelsammelbehälters gebildet und entstehen ebenso wie der Schmiermittelsammelbehälter direkt beim Gießen des Zylinder- kurbelgehäuses.In this case, at least parts of the housing of the lubricant pump are also formed by the wall of the lubricant reservoir and arise as well as the lubricant reservoir directly when casting the cylinder crankcase.
Im Bereich der Kurbelwelle ist wie üblich eine Trockensumpfrückförderpumpe angeordnet, die über mindestens einen Verbindungskanal mit dem Schmiermittelsammelbehälter verbunden ist. Die Trockensumpfrückförderpumpe fördert aus einem kleinen Sammelraum unterhalb der Kurbelwelle Schmiermittel über den Verbindungskanal in den zwischen den Zylinderreihen angeordneten Schmiermittelsammelbehälter.In the region of the crankshaft, as usual, a dry pump return pump is arranged, which is connected via at least one connecting channel with the lubricant collecting container. The dry pump return pump conveys lubricant from a small plenum below the crankshaft via the connecting channel in the arranged between the rows of cylinders lubricant reservoir.
Der mindestens eine Verbindungskanal kann dabei vorteilhaft an der Wandung des Zylinderkurbelgehäuses ausgebildet werden und entsteht ebenfalls beim Gießen des Zylinderkurbelgehäuses. In einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Oberseite des Schmiermittelsammelbehälters einen demontierbaren Deckel aufweist. Der demontierbare Deckel wird vorzugsweise mit dem Zylinderkurbelgehäuse verschraubt.The at least one connecting channel can advantageously be formed on the wall of the cylinder crankcase and also arises during casting of the cylinder crankcase. In an advantageous development of the invention, it is provided that the upper side of the lubricant collecting container has a removable lid. The removable cover is preferably bolted to the cylinder crankcase.
In einer nächsten vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der demontierbare Deckel als Komponententräger ausgebildet ist.In a next advantageous embodiment of the invention it is provided that the removable lid is designed as a component carrier.
Zudem ist der demontierbare Deckel zur Wartung der Schmiermittelpumpe ausgebildet. In einer letzten vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Schmiermittelkreislauf einen Schmiermittelfilter aufweist, und dass der Schmiermittelfilter mit dem demontierbaren Deckel verbunden ist.In addition, the removable cover for maintenance of the lubricant pump is formed. In a last advantageous development of the invention, it is provided that the lubricant circuit has a lubricant filter, and that the lubricant filter is connected to the removable cover.
Durch den innerhalb des Zylinderkurbelgehäuses im Bauraum zwischen den Zylindern angeordneten Schmiermittelsammelbehälter wird im Motorraum einesBy arranged within the cylinder crankcase in the space between the cylinders lubricant reservoir is in the engine compartment of a
Kraftfahrzeugs nur ein unwesentlich größerer Bauraum benötigt, der sogar die Außenabmessung der Brennkraftmaschine weitgehend unbeeinflusst lässt. Eine Verschlauchung des Schmiermittelsammelbehälters außerhalb der Brennkraftmaschine entfällt. Zudem sind die Mehrkosten beim Gießen des Zylinderkurbel- gehäuses minimal und ersetzen die Kosten für den separaten Schmiermittelsammelbehälter vollständig. Weitere Bauraum- und Kostenvorteile entstehen durch die Integration des Schmiermittelpumpengehäuses in das Zylinderkurbelgehäuse.Motor vehicle requires only a slightly larger space, which leaves even the outer dimensions of the engine largely unaffected. A tubing of the lubricant reservoir outside the internal combustion engine is eliminated. In addition, the extra costs when casting the cylinder crankcase are minimal and replace the cost of the separate lubricant reservoir completely. Further installation space and cost advantages result from the integration of the lubricant pump housing into the cylinder crankcase.
Im Folgenden ist der erfindungsgemäße Brennkraftmaschine mit einem inner- halb des Zylinderkurbelgehäuses im Bauraum zwischen den Zylindern angeordneten Schmiermittelsammelbehälter anhand von einem Ausführungsbeispiel im Zusammenhang mit einer Figur dargestellt und erläutert.In the following, the internal combustion engine according to the invention is shown and explained with reference to an exemplary embodiment in connection with a figure with a lubricant reservoir arranged inside the cylinder crankcase in the installation space between the cylinders.
Es zeigt:It shows:
die Figur eine schematische Darstellung der Brennkraftmaschine mit dem im v-Raum angeordneten Schmiermittelsammelbehälter.the figure is a schematic representation of the internal combustion engine with the arranged in v-space lubricant reservoir.
Eine Öl als Schmiermittel verwendende v-förmige Brennkraftmaschine weist ei- nen Trockensumpf Druckölkreislauf auf, dessen Ölsammelbehälter zwischen den zwei Zylinderreihen angeordnet ist, wobei der Ölsammelbehälter einteilig mit dem Zylinderkurbelgehäuse beim Gießen des Zylinderkurbelgehäuses gebildet ist.A V-shaped internal combustion engine using oil as a lubricant has a dry sump pressure oil circuit whose oil sump is disposed between the two banks of cylinders, the oil sump being integrally formed with the cylinder crankcase in casting the cylinder crankcase.
Die Figur zeigt einen Querschnitt durch eine derartige Brennkraftmaschine 1. Der nur andeutungsweise dargestellte Druckölkreislauf 6 wird von einer Außenzahnrad- Ölpumpe 7 angetrieben, die innerhalb des Ölsammelbehälters 2 angeordnet ist, und die alle wesentlichen Schmierstellen der Brennkraftmaschine 1 versorgt.The figure shows a cross section through such an internal combustion engine 1. The only hinted pressure oil circuit 6 is driven by an external gear oil pump 7, which is disposed within the oil collecting container 2, and supplies all the essential lubrication points of the internal combustion engine 1.
Gefüllt wird der Ölsammelbehälter 2 über eine Trockensumpfrückförderpumpe 10, die am Boden des Kurbelwellengehäuses 3 bei einem kleinen Sammelraum 5 angeordnet ist, der das von den Schmierstellen zurückfließende Öl aufnimmt. Die Verbindung zwischen der Trockensumpfrückförderpumpe 8 und der Außenzahnrad- Ölpumpe 7 wird von einer Ölleitung 9 gebildet, die vorzugsweise bei Gießen des Zylinderkurbelgehäuses 4 und Kurbelwellengehäuses 3 entsteht, die aber auch als separates Bauteil ausgebildet werden kann.The oil reservoir 2 is filled via a dry pump return pump 10, which at the bottom of the crankcase 3 at a small plenum 5 is arranged, which receives the oil flowing back from the lubrication points. The connection between the dry pump return pump 8 and the external gear oil pump 7 is formed by an oil line 9, which is preferably formed when casting the cylinder crankcase 4 and crankcase 3, but which can also be formed as a separate component.
Der Ölsammelbehälter 2 wird von einem mittels Schrauben demontierbaren Deckel 8 abgedeckt, über welchen die im Innenraum des Ölsammelbehälters 2 angeordnete Außenzahnrad- Ölpumpe 7 gewartet werden kann. Dabei ist vorgesehen, dass Teile des Gehäuses der Außenzahnrad- Ölpumpe 7 oder zumindest Aufnahmen für die Außenzahnrad- Ölpumpe 7 beim Gießen des Zylinderkurbelgehäuses 4 ausgebildet werden.The oil collecting container 2 is covered by a removable cover by means of screws cover 8, via which the arranged in the interior of the oil collecting 2 external gear oil pump 7 can be maintained. It is provided that parts of the housing of the external gear oil pump 7 or at least receptacles for the external gear oil pump 7 are formed during casting of the cylinder crankcase 4.
Der demontierbare Deckel 8 ist als Träger für weitere Komponenten der Brennkraftmaschine ausgebildet. So ist an dem demontierbaren Deckel 8 eine Aufnahme für einen Ölfilter ausgebildet. Das beschriebene Zylinderkurbelgehäuse mit dem zwischen den Zylindern angeordneten Ölsammelbehälter benötigt einen geringen Bauraum und verursacht beim Gießen des Zylinderkurbelgehäuses kaum höhere Kosten. Eine Verschlau- chung des Ölsammelbehälters außerhalb der Brennkraftmaschine entfällt. The removable cover 8 is designed as a carrier for other components of the internal combustion engine. Thus, a receptacle for an oil filter is formed on the removable cover 8. The cylinder crankcase described with the arranged between the cylinders oil reservoir requires a small space and caused when casting the cylinder crankcase hardly higher costs. An entrapment of the oil collection container outside the internal combustion engine is eliminated.
