On its bottom part, the SMBP extends through a tubular connecting piece that has filter netting on its free end and forms a segment in a suction pipe.

Description

Die Erfindung betrifft eine Ölwanne nach dem Oberbegriff des Anspruchs 1.The invention relates to an oil pan according to the preamble of claim 1.

Es sei darauf hingewiesen, dass im Rahmen dieser Beschreibung die Ausdrücke "oben", "unten", "oberhalb" und "unterhalb" sich auf die auf den Motorblock montierte Ölwanne in normaler Betriebsposition beziehen.It should be noted that throughout this specification, the terms "up", "down", "above" and "below" refer to the engine block mounted sump in normal operating position.

Eine solche Ölwanne ist aus dem US 6, 290, 843 bekannt.Such an oil pan is from the US 6, 290, 843 known.

Das wesentliche Merkmal der Ölwanne, die Gegenstand der Erfindung ist, ist somit gebunden an das Vorhandensein der Verbindungsplatte aus synthetischem Material, welche eine Schnittstelle darstellt, die es erlaubt, die notwendige Dichtigkeit zwischen dem Wannenkörper und dem Motorblock dank des Vorhandenseins von zwei Umfangsdichtungen zu erreichen, die auf deren jeweilige Flächen gegossen werden, und welche gleichzeitig erlaubt, mit der Ölpumpe das im Inneren des Wannenkörpers befindliche Schmieröl abzusaugen.The essential feature of the oil sump, which is the subject of the invention is thus bound to the presence of the connecting plate of synthetic material, which represents an interface, which makes it possible to achieve the necessary tightness between the bucket body and the engine block thanks to the presence of two circumferential seals , which are poured onto their respective surfaces, and at the same time allows to suck with the oil pump located in the interior of the tub body lubricating oil.

Diese Verbindungsplatte muss selbstverständlich mit Durchlassöffnungen für das Öl versehen sein, das in den Wannenkörper zurückläuft sowie mit Bohrungen für den Schaft der Befestigungsschrauben der Ölwanne auf dem Motorblockgehäuse.This connection plate must of course be provided with passage openings for the oil that runs back into the tub body and with holes for the shaft of the mounting screws of the oil pan on the engine block housing.

Was den Wannenkörper betrifft, so besteht dieser aus einem Element in Form eines Gefäßes, dessen untere Wandung geneigt ist und das am unteren Ende mit einer Ablassöffnung versehen ist, die mit einem Verschlussdeckel verschlossen ist.As far as the body of the bath is concerned, it consists of an element in the form of a vessel whose lower wall is inclined and which at the lower end is provided with a discharge opening which is closed by a closure lid.

Die Ölwanne, die Gegenstand der Erfindung ist, unterscheidet sich von den herkömmlichen Ölwannen aus Aluminium durch ihr geringeres Gewicht und durch deutlich niedrigere Herstellungs- und Montagekosten.The oil sump, which is the subject of the invention, differs from the conventional aluminum sumps by their lower weight and by significantly lower manufacturing and assembly costs.

Gemäß eines bevorzugten Merkmals der Erfindung wird der Wannenkörper durch den Zusammenbau von zwei Schalen gebildet, d.h. einer unteren Schale in Form eines Gefäßes und einer oberen Schale, die mit dieser verschweißt ist und die Verbindungsplatte enthält.According to a preferred feature of the invention, the tub body is formed by the assembly of two shells, ie a lower shell in the form of a vessel and an upper shell which is welded thereto and contains the connection plate.

Die Verbindungsplatte und die obere Schale liegen somit zwischen der unteren Schale und dem Motorblock des Verbrennungsmotors.The connecting plate and the upper shell are thus between the lower shell and the engine block of the internal combustion engine.

Diese beiden Schalen können vorzugsweise mittels einer Heizplatte kontaktlos verschweißt werden.These two shells can preferably be welded without contact by means of a heating plate.

Ein derartiges Schweißverfahren hat den Vorteil, dass man sehr kleine Schweißnähte erhält verglichen vor allem mit einem herkömmlichen Vibrationsschweißen.Such a welding method has the advantage that one obtains very small welds compared especially with a conventional vibration welding.

Hinsichtlich der Ausführungsform kann die Ölwanne erfindungsgemäß ein deutlich höheres Fassungsvermögen haben als die zur Zeit auf dem Markt angebotenen herkömmlichen und vergleichbaren Ölwannen.With regard to the embodiment, the oil sump according to the invention can have a significantly higher capacity than the conventional and comparable oil sumps currently available on the market.

Gemäß eines weiteren Merkmals der Erfindung erstreckt sich die untere Wandung der unteren Schale nach oben mittels röhrenartiger, parallel verlaufender Säulen, die an ihrem oberen Ende einen Absatz haben, der einen Anschlag für den Kopf der Befestigungsschraube der Ölwanne auf dem Motorblockgehäuse bildet.According to a further feature of the invention, the bottom wall of the lower shell extends upwards by means of tubular, parallel columns which have at their upper end a shoulder which forms a stop for the head of the mounting screw of the oil pan on the engine block housing.

Die obere Schale und die Verbindungsplatte sind mit paarweise angeordneten Bohrungen für die Schäfte dieser Schrauben versehen, damit sie auf der unteren Wandung des Motorblockgehäuses angeschraubt werden können und die beiden Umfangsdichtungen zusammenpressen, die auf die Verbindungsplatte zwischen der oberen Schale und dem Motorblockgehäuse ausgegossen werden, um so eine radiale Dichtigkeit zwischen der Ölwanne und dem Motorblock zu gewährleisten.The upper shell and the connecting plate are provided with paired holes for the shanks of these screws so that they can be screwed onto the lower wall of the engine block housing and compress the two circumferential seals which are poured onto the connecting plate between the upper shell and the engine block housing to ensure a radial tightness between the oil pan and the engine block.

Gemäß Abb. 1 besteht die Ölwanne aus einem Wannenkörper 1 aus synthetischem Material, der an seinem oberen Teil durch eine Verbindungsplatte 2, ebenfalls aus synthetischem Material, verschlossen ist.According to Fig. 1 the sump consists of a tub body 1 made of synthetic material, which is closed at its upper part by a connecting plate 2, also made of synthetic material.

Der Wannenkörper 1 wird mittels der Befestigungsschrauben 3 am Motorblockgehäuse des Verbrennungsmotors, der hier nicht in den Abbildungen dargestellt ist, befestigt.The tub body 1 is fastened by means of the fastening screws 3 on the engine block housing of the internal combustion engine, which is not shown here in the figures.

Wie weiter unten im Detail beschrieben liegt die Verbindungsplatte 2 zwischen dem Wannenkörper 1 und dem Motorblockgehäuse.As described in detail below, the connection plate 2 is located between the tub body 1 and the engine block housing.

Gemäß den Abbildungen 2 und 4 erstreckt sich die Verbindungsplatte 2 auf ihrer unteren Fläche mittels eines röhrenförmigen Anschlussstückes 5, welches eine Ansaugöffnung 7 umgibt und an seinem freien Ende mit einem Filternetz 6 ausgestattet ist.Referring to Figures 2 and 4, the connecting plate 2 extends on its lower surface by means of a tubular fitting 5 which surrounds a suction port 7 and is provided at its free end with a filter net 6.

Dieses röhrenförmige Anschlussstück 5 bildet ein Segment einer Saugleitung, die an eine nicht in den Abbildungen dargestellte Ölpumpe angeschlossen ist, um so das im Wannenkörper 1 gelagerte Öl zu den verschiedenen Teilen des Motors zu leiten, die geschmiert werden müssen.This tubular fitting 5 forms a segment of a suction pipe which is connected to an oil pump not shown in the figures so as to guide the oil stored in the body 1 to the various parts of the engine which need to be lubricated.

Die auf der Oberfläche der Verbindungsplatte 2 gebohrten Öffnungen 4 ermöglichen den Rückfluss des überschüssigen Öls in den Wannenkörper 1.The holes 4 bored on the surface of the connection plate 2 allow the excess oil to reflux into the tub body 1.

Gemäß den Abbildungen 1 und 4 ist die Verbindungsplatte 2 auf jeder ihrer Seiten mit einer Umfangsdichtung 8, 9 ausgestattet bzw. darauf ausgegossen.According to Figures 1 and 4, the connecting plate 2 is provided on each of its sides with a peripheral seal 8, 9 and poured thereon.

Die Verbindungsplatte 2 ist außerdem auf ihrem Umfang mit einer Reihe Bohrungen 19, 20 ausgestattet, die das Ziel haben, den Schaft der Befestigungsschrauben aufzunehmen.The connecting plate 2 is also provided on its periphery with a series of holes 19, 20, which aim to receive the shank of the fastening screws.

Einige dieser Bohrungen 19 befinden sich an der Innenseite der Umfangsdichtungen 8, 9, während sich die anderen Bohrungen 20 an der Außenseite dieser Dichtungen befinden.Some of these holes 19 are located on the inside of the circumferential seals 8, 9, while the other holes 20 are located on the outside of these seals.

Wenn der Wannenkörper 1 auf das Motorblockgehäuse aufgeschraubt wird, werden die beiden Umfangsdichtungen 8, 9 so zusammengedrückt, dass sie hier die Dichtigkeit gewährleisten.When the tub body 1 is screwed onto the engine block housing, the two circumferential seals 8, 9 are compressed so that they ensure the tightness here.

Gemäß den Abbildungen 2 und 3 wird der Wannenkörper 1 durch den Zusammenbau einer unteren Schale in Form eines Gefäßes 10 und einer oberen Schale 11, die auf diese an ihrem Umfang aufgeschweißt wird, gebildet.Referring to Figs. 2 and 3, the tub body 1 is formed by assembling a lower shell in the form of a vessel 10 and an upper shell 11 welded thereto at its periphery.

Die untere Schale 10 wird detaillierter in den Abbildungen 5 und 6 dargestellt.The lower shell 10 is shown in more detail in Figures 5 and 6.

Die obere Schale 11 wird detaillierter in den Abbildungen 7 und 8 dargestellt.The upper shell 11 is shown in more detail in Figures 7 and 8.

Gemäß den Abbildungen 2, 3, 4, 5 und 6 ist die untere Fläche der unteren Schale 10 geneigt und erstreckt sich seitlich über einen Kanal 12 bis zu einem niedrig liegenden Punkt, der mit einer durch einen Verschlussdeckel 13 verschlossenen Ablassöffnung ausgestattet ist.As shown in FIGS. 2, 3, 4, 5 and 6, the lower surface of the lower shell 10 is inclined and extends laterally via a channel 12 to a low point provided with a discharge port closed by a cap 13.

Die untere Fläche der unteren Schale 10 erstreckt sich auch nach oben durch eine Reihe röhrenförmiger, parallel verlaufender Säulen 14, deren Verwendungszweck es ist, die Befestigungsschrauben 3 des Wannenkörpers 1 aufzunehmen und sie auf dem Motorblockgehäuse einzusetzen.The lower surface of the lower shell 10 also extends upwardly through a series of tubular, parallel columns 14, the purpose of which is to receive the mounting screws 3 of the tub body 1 and insert them on the engine block housing.

Gemäß den Abbildungen 7 und 8 hat die obere Schale 11 eine Geometrie, die diejenige der unteren Schale 10 ergänzt und sich ebenfalls seitlich durch eine Rippe 15 erstreckt, die dem Kanal 12 entspricht.As shown in Figures 7 and 8, the upper shell 11 has a geometry which complements that of the lower shell 10 and also extends laterally through a rib 15 corresponding to the channel 12.

Die obere Schale 11 ist außerdem um ihren Umfang herum mit einem Ring 16 ausgestattet, der mit Bohrungen versehen ist, die jeweils den Bohrungen 19, 20 der Verbindungsplatte 2 entsprechen, die den Schaft der Befestigungsschrauben 3 aufnehmen.The upper shell 11 is also provided around its circumference with a ring 16 provided with bores corresponding respectively to the bores 19, 20 of the connecting plate 2 which receive the shank of the fixing screws 3.

Gemäß den Abbildungen 2 und 3 ragt ein Teil des Ringes 16 der oberen Schale 11 seitlich über die untere Schale 10 hinaus.As shown in Figures 2 and 3, part of the ring 16 of the upper shell 11 projects laterally beyond the lower shell 10.

Die Bohrungspaare 18, 20, die auf diesem herausragenden Teil angebracht sind und die außerhalb der Umfangsdichtungen 8, 9 liegen, nehmen die Befestigungsschrauben 3 direkt auf.The pairs of holes 18, 20 which are mounted on this protruding part and which are outside the circumferential seals 8, 9, take the mounting screws 3 directly.

Die anderen Bohrungspaare 17, 19 befinden sich jeweils rechts von dem oberen Ende einer röhrenförmigen Säule 14 der unteren Schale 10 innerhalb der Umfangsdichtungen 8, 9.The other pairs of holes 17, 19 are each located to the right of the upper end of a tubular column 14 of the lower shell 10 within the perimeter seals 8, 9.
