Description

Die Erfindung bezieht sich auf eine Ölwanne, insbesondere für eine Brennkraftmaschine, nach dem Oberbegriff des Anspruches 1.The invention relates to an oil pan, in particular for an internal combustion engine, according to the preamble of claim 1.

In der Druckschrift EP 1 041 253 B1 wird eine Ölwanne für eine Brennkraftmaschine beschrieben, die aus einem thermoplastischen Kunststoff mit auf der Außenwand angespritzten Rippen besteht, welche die Ölwanne vor starken mechanischen Einwirkungen wie z. B. Steinschlag schützen sollen. Am Wannenboden sind mehrere, zueinander beabstandete Rippen angeordnet, die zum Teil eine erhöhte Steifigkeit aufweisen, wodurch mechanische Kräfte besser aufgenommen werden können.In the publication EP 1 041 253 B1 an oil pan for an internal combustion engine is described, which consists of a thermoplastic material with molded on the outer wall ribs, which protects the oil pan from strong mechanical effects such. To protect rockfall. At the bottom of the tub, a plurality of spaced-apart ribs are arranged, some of which have increased rigidity, whereby mechanical forces can be better absorbed.

Die Ölwanne wird auf der Unterseite des Kurbelgehäuses der Brennkraftmaschine montiert und nimmt das Motoröl auf. Bei der Montage des Motors in das Fahrzeug oder zu Wartungs- bzw. Reparaturzwecken muss gegebenenfalls der Motor auf dem Boden abgestellt werden und die auf der Unterseite des Motors befindliche Ölwanne das Gewicht des Motors aufnehmen muss. Falls der Motor in schräger Position oder auf unebenem Boden abgestellt wird, werden einzelne Rippen auf der Unterseite der Ölwanne sehr hoch belastet, wodurch die Gefahr besteht, dass diese Rippen brechen.The oil pan is mounted on the underside of the crankcase of the engine and receives the engine oil. When installing the engine in the vehicle or for service or repair purposes, the engine may need to be parked on the ground and the oil sump located on the bottom of the engine must accept the weight of the engine. If the engine is parked in an inclined position or on uneven ground, individual ribs on the underside of the oil sump are subjected to very high loads, which could cause these ribs to break.

Diese Gefahr besteht auch, wenn das Fahrzeug während der Fahrt versehentlich auf dem Boden aufsetzt, oder im Falle eines starken Steinschlages. Die hierbei auftretende, lokal eng begrenzte Krafteinwirkung kann zu einer Beschädigung der Rippen sowie der Wandung der Ölwanne führen, was die Gefahr des Auslaufens von Öl nach sich zieht.This danger also exists if the vehicle accidentally touches the ground while driving, or in the case of a strong rock impact. The occurring locally, locally limited force can cause damage to the ribs and the wall of the oil pan, which entails the risk of leakage of oil.

Ein weiteres Problem liegt in der Resonanzverstärkung der Motorschwingungen über die Ölwanne. Die Motorschwingungen werden trotz Maßnahmen zur Schwingungsentkopplung teilweise auf die Ölwanne übertragen, die in der gleichen Frequenz mitschwingt, wobei aufgrund des verhältnismäßig großen Resonanzkörpers der Ölwanne eine erhebliche Geräuschentwicklung entstehen kann.Another problem is the resonance amplification of the engine vibrations via the oil sump. The engine vibrations are partially transferred to the oil pan despite measures for vibration isolation, in the same frequency resonates, which can cause considerable noise due to the relatively large resonator of the oil pan.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen konstruktiven Maßnahmen den Schutz einer Ölwanne vor Beschädigungen zu verbessern. Dieser Schutz soll zweckmäßig ohne signifikante Gewichtserhöhung der Ölwanne einhergehen. Darüber hinaus soll vorteilhaft auch die Geräuschentwicklung, die durch eine mitschwingende Ölwanne entstehen kann, eingedämmt werden.The invention is based, to improve the protection of an oil pan from damage with simple constructive measures the task. This protection should be accompanied by appropriate without significant increase in weight of the oil pan. In addition, the noise, which can be caused by a resonant oil sump, should also be contained in an advantageous manner.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.This object is achieved with the features of claim 1. The dependent claims indicate expedient developments.

Die Schutzeinrichtung der erfindungsgemäßen Ölwanne ist als flexible und öldichte Schutzmembrane ausgebildet, die die Innenwand der Ölwanne abdeckt. Diese Lösung bietet den Vorteil, dass im Fall einer von außen auf die Ölwanne einwirkenden hohen Kraft, die zu einer Zerstörung der Wandung der Ölwanne führen kann, das im Innenraum befindliche Öl trotz Leck in der Wandung von der Schutzmembrane zurückgehalten wird. Die Schutzmembrane ist fest mit der Ölwanne verbunden und folgt der Kontur der Innenwand der Ölwanne, so dass das Fassungsvermögen der Ölwanne durch die Schutzmembrane praktisch nicht eingeschränkt ist.The protective device of the oil pan according to the invention is designed as a flexible and oil-tight protective membrane covering the inner wall of the oil pan. This solution has the advantage that in the event of a force acting from the outside on the oil pan high force that can lead to destruction of the wall of the oil pan, the oil in the interior is retained despite leakage in the wall of the protective membrane. The protective membrane is firmly connected to the oil pan and follows the contour of the inner wall of the oil pan, so that the capacity of the oil pan through the protective membrane is practically not limited.

Die flexible, folienartige Schutzmembrane bewirkt außerdem eine Geräuschdämpfung. Die Energie der in die Ölwanne eingeleiteten Schwingungen, insbesondere der Motorschwingungen, wird von der, in Kontakt mit der Innenwand der Ölwanne stehenden, Schutzmembrane zumindest teilweise absorbiert. Diese Geräuschdämpfung kann dadurch noch gesteigert werden, dass zwischen der Innenwand und der flexiblen Schutzmembrane ein Hohlraum gebildet ist, der von der Schutzmembrane zweckmäßig gasdicht eingeschlossen ist, oder eine Matte eingelegt wird.The flexible, film-like protective membrane also causes a noise attenuation. The energy of the vibrations introduced into the oil sump, in particular the engine vibrations, is at least partially absorbed by the protective membrane in contact with the inner wall of the oil sump. This noise attenuation can be further increased, that between the inner wall and the flexible protective membrane, a cavity is formed, which is suitably enclosed gas-tight by the protective membrane, or a mat is inserted.

Dieser Hohlraum entsteht beispielsweise dadurch, dass Stützkonturelemente zwischen Innenwand und Schutzmembrane vorgesehen sind, die die Schutzmembrane auf Abstand zur Innenwand halten. Diese Abstandshalter bzw. Stützkonturelemente können gemäß einer vorteilhaften Ausbildung an die Schutzmembrane angespritzt sein. Die Stützkonturelemente halten die Schutzmembrane zweckmäßig auf einen etwa gleichbleibenden Abstand zur Innenwand der Ölwanne. Das zwischen Innenwand und Schutzmembran eingeschlossene Luftpolster wirkt gemeinsam mit der flexiblen Membrane als akustisches Dämpfersystem und hilft, die Geräuschemissionen, insbesondere des Kurbeltriebes, zu reduzieren.This cavity is formed, for example, by providing support contour elements between the inner wall and the protective membrane, which keep the protective membrane at a distance from the inner wall. These spacers or support contour elements can be molded onto the protective membrane according to an advantageous embodiment. The support contour elements keep the protective membrane expedient to an approximately constant distance from the inner wall of the oil pan. The air cushion enclosed between the inner wall and the protective membrane acts together with the flexible membrane as an acoustic damper system and helps to reduce the noise emissions, in particular of the crank mechanism.

Die Schutzmembrane ist zweckmäßig fest mit einer am oberen Rand der Ölwanne angeordneten Dichtung verbunden, über die die Ölwanne vom Kurbelgehäuse des Motors schwingungsisoliert ist. Es kann auch vorteilhaft sein, die Schutzmembrane an diese Dichtung anzuspritzen, also die Dichtung einschließlich der Schutzmembrane als gemeinsames Spritzgussbauteil auszuführen. In jedem Fall besteht die Schutzmembrane aus einem flexiblen, nachgiebigen Material, gegebenenfalls aus dem gleichen Material wie die Dichtung.The protective diaphragm is suitably fixedly connected to a seal arranged at the upper edge of the oil sump, via which the oil sump is vibration-isolated from the crankcase of the engine. It may also be advantageous to inject the protective membrane to this seal, ie to carry out the seal including the protective membrane as a common injection-molded component. In any case, the protective membrane is made of a flexible, resilient material, possibly of the same material as the gasket.

Die Schutzmembrane deckt insbesondere den gesamten Innenbereich der Ölwanne ab und erstreckt sich bis zu der Dichtung, wodurch sichergestellt ist, dass keine Fläche der Innenwand der Ölwanne unmittelbar mit dem Öl in Kontakt gelangt. Unabhängig vom Ort einer möglichen Beschädigung der Ölwanne wird dadurch gewährleistet, dass das Öl von der Schutzmembrane aufgefangen wird und nicht über die Leck geschlagene Wandung austreten kann.In particular, the protective membrane covers the entire interior of the oil pan and extends to the seal, ensuring that no surface of the inner wall of the oil pan comes into direct contact with the oil. Regardless of the location of a possible damage to the oil pan, this ensures that the oil is collected by the protective membrane and can not escape through the leak beaten wall.

Weitere Vorteile und zweckmäßige Ausführungen sind den weiteren Ansprüchen, der Figurenbeschreibung und der Zeichnung zu entnehmen, die einen Schnitt durch eine Ölwanne für eine Brennkraftmaschine zeigt.Further advantages and expedient embodiments can be taken from the further claims, the description of the figures and the drawing, which shows a section through an oil pan for an internal combustion engine.

Die in der Figur dargestellte Ölwanne 1 für eine Brennkraftmaschine eines Kraftfahrzeuges besteht aus Kunststoff und wird insbesondere im Spritzgussverfahren hergestellt. Zum Schutz gegen austretendes ÖI im Falle einer Beschädigung der Wandung 2 der Ölwanne 1 ist die Innenwand der Ölwanne von einer flexiblen, nachgiebigen, folienartigen Schutzmembrane 4 abgedeckt. Die flexible Schutzmembrane 4 ist zweckmäßig einteilig mit einer Dichtung 5 ausgebildet, insbesondere an dieser angespritzt, welche im oberen, umlaufenden Randbereich 6 der Wandung 2 angeordnet ist und bei montierter Ölwanne zwischen der Wandung 2 der Ölwanne und der Unterseite eines schematisch dargestellten Kurbelgehäuses 8 einer Brennkraftmaschine liegt. Des Weiteren sind im oberen, umlaufenden Randbereich 6 der Wandung 2 Befestigungselemente 7 vorgesehen, über die die Ölwanne 1 mit dem Kurbelgehäuse 8 zu verbinden ist.The illustrated in the figure, oil pan 1 for an internal combustion engine of a motor vehicle consists of plastic and is produced in particular by injection molding. To protect against escaping oil in the event of damage to the wall 2 of the oil pan 1, the inner wall of the oil pan is covered by a flexible, resilient, foil-like protective membrane 4. The flexible protective membrane 4 is expediently integrally formed with a seal 5, in particular molded on this, which is arranged in the upper, peripheral edge region 6 of the wall 2 and mounted sump between the wall 2 of the oil pan and the bottom of a schematically illustrated crankcase 8 of an internal combustion engine lies. Furthermore, fastening elements 7 are provided in the upper circumferential edge region 6 of the wall 2 via which the oil sump 1 is to be connected to the crankcase 8.

Gegebenenfalls ist die Schutzmembrane 4 auch separat, also unabhängig von der Dichtung 5 ausgebildet. In diesem Fall kann es aber zweckmäßig sein, die Schutzmembrane 4 mithilfe geeigneter Verbindungselemente fest mit der Dichtung 5 zu verbinden. Möglich ist aber auch, auf eine Verbindung zwischen Dichtung 5 und Schutzmembrane 4 zu verzichten; in diesem Fall ist die Schutzmembrane 4 vorteilhaft unmittelbar mit dem oberen, umlaufenden Randbereich 6 der Wandung 2 der Ölwanne verbunden.Optionally, the protective membrane 4 is also separate, that is formed independently of the seal 5. In this case, it may be appropriate to connect the protective membrane 4 by means of suitable fasteners fixed to the seal 5. But it is also possible to dispense with a connection between the seal 5 and protective membrane 4; In this case, the protective membrane 4 is advantageously connected directly to the upper, peripheral edge region 6 of the wall 2 of the oil pan.

Die Schutzmembrane 4 ist über Stützkonturelemente 9 auf Abstand zur Innenwand 3 der Wandung 2 der Ölwanne gehalten. Diese Stützkonturelemente 9 sind vorteilhaft an die Schutzmembrane 4 angespritzt und bestehen insbesondere aus dem gleichen Material wie die Schutzmembran. Die Stützkonturelemente 9 halten die Schutzmembrane 4 auf Abstand zur Innenwand 3, wodurch zwischen Innenwand 3 und Schutzmembrane 4 ein Hohlraum 10 gebildet ist. Die Schutzmembrane 4 ist gas- und öldicht ausgebildet, wodurch der Hohlraum 10 gasdicht isoliert ist und das ÖI der Ölwanne 1 nicht mit dem im Hohlraum befindlichen Luftpolster in Kontakt gelangen kann.The protective membrane 4 is held by support contour elements 9 at a distance from the inner wall 3 of the wall 2 of the oil pan. These support contour elements 9 are advantageously molded onto the protective membrane 4 and consist in particular of the same material as the protective membrane. The support contour elements 9 keep the protective membrane 4 at a distance from the inner wall 3, whereby a cavity 10 is formed between the inner wall 3 and the protective membrane 4. The protective membrane 4 is formed gas- and oil-tight, whereby the cavity 10 is isolated in a gastight manner and the oil of the oil pan 1 can not come into contact with the air cushion located in the cavity.

In einer alternativen Ausführung sind die Stützkonturelemente 9 nicht einteilig mit der Schutzmembrane 4 ausgebildet, sondern bilden separate Abstandselemente, die beispielsweise an der Innenwand 3 der Ölwanne befestigt werden und auf die die Schutzmembrane 4 aufgelegt wird.In an alternative embodiment, the support contour elements 9 are not formed integrally with the protective membrane 4, but form separate spacer elements, which are fastened, for example, to the inner wall 3 of the oil pan and on which the protective membrane 4 is placed.

Die Schutzmembrane 4 bedeckt zweckmäßig die gesamte Innenwand 3, soweit diese in Kontakt mit dem Öl gelangen kann. Auf diese Weise wird ein vollständiger Schutz der Innenwand erreicht und insbesondere für den Fall einer Beschädigung der Wandung 2 ein Auslaufen von Öl verhindert.The protective membrane 4 expediently covers the entire inner wall 3, as far as it can come into contact with the oil. In this way, a complete protection of the inner wall is achieved and in particular in the event of damage to the wall 2 prevents leakage of oil.
