In order to provide an oil sump, comprising a basic body with a main oil chamber and a wall, which oil sump can be adapted particularly simply to different oil collecting volumes which are required in each case, it is proposed that the oil sump comprises at least one additional oil chamber and the wall has at least one through opening, by which the additional oil chamber is connected to the main oil chamber of the basic body.

Description

Die vorliegende Erfindung betrifft eine Ölwanne, die einen Grundkörper mit einer Hauptölkammer und einer Wandung umfasst.The present invention relates to an oil pan comprising a main body with a main oil chamber and a wall.

Solche Ölwannen zur Montage an einem Verbrennungsmotor sind aus dem Stand der Technik bekannt.Such oil pans for mounting on an internal combustion engine are known from the prior art.

Bei den bekannten Ölwannen wird der Grundkörper der Ölwanne so dimensioniert, dass er das für den jeweiligen Anwendungsfall benötigte Ölsammelvolumen aufweist.In the known oil pans of the main body of the oil pan is dimensioned so that it has the required oil volume for the particular application.

Die FR 1 102 169 A offenbart eine Ölwanne gemäß dem Oberbegriff von Anspruch 1.The FR 1 102 169 A discloses an oil pan according to the preamble of claim 1.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ölwanne der eingangs genannten Art zu schaffen, welche besonders einfach an unterschiedliche jeweils benötigte Ölsammelvolumina anpassbar ist.The present invention has for its object to provide an oil pan of the type mentioned, which is particularly easy to adapt to different oil collection volumes required in each case.

Diese Aufgabe wird durch eine Ölwanne nach Anspruch 1 gelöst.This object is achieved by an oil pan according to claim 1.

Durch die Zusatzölkammer, deren Innenraum ein zusätzliches Ölsammelvolumen zur Verfügung stellt, welches durch die Durchtrittsöffnung in der Wandung mit dem Ölsammelvolumen im Innenraum des Grundkörpers verbunden ist, weist die erfindungsgemäße Ölwanne ein größeres Ölsammelvolumen auf als eine Ölwanne, welche lediglich aus dem Grundkörper gebildet wäre.By the additional oil chamber whose interior provides an additional oil collection volume, which is connected through the passage opening in the wall with the oil collection volume in the interior of the body, the oil pan according to the invention has a larger oil collection volume than an oil pan, which would be formed only from the main body.

Durch geeignete Wahl der Größe der Zusatzölkammer oder durch das Vorsehen mehrerer Zusatzölkammern kann das Gesamt-Ölsammelvolumen der Ölwanne an jeden beliebigen Anwendungsfall angepasst werden, ohne dass hierzu der Grundkörper und insbesondere ein Montageflansch, über welchen die Ölwanne mit einem Verbrennungsmotor verbunden wird, modifiziert werden müssen.By a suitable choice of the size of the auxiliary oil chamber or by the provision of several additional oil chambers, the total oil collection volume of the oil pan can be adapted to any application, without For this purpose, the main body and in particular a mounting flange, via which the oil pan is connected to an internal combustion engine, must be modified.

Dadurch kann die erfindungsgemäße Ölwanne besonders einfach an unterschiedliche Einbausituationen und an den jeweils zur Verfügung stehenden Motorraum angepasst werden.As a result, the oil pan according to the invention can be adapted particularly easily to different installation situations and to the respectively available engine compartment.

Es ist auch denkbar, eine bereits bestehende Ölwanne nachträglich mit einer Zusatzölkammer zu versehen, wenn ein größeres Ölsammelvolumen benötigt wird.It is also conceivable to provide an existing oil sump subsequently with an additional oil chamber, if a larger oil collection volume is needed.

Die in der Wandung des Grundkörpers vorgesehene Durchtrittsöffnung ist durch die Zusatzölkammer verschlossen.The provided in the wall of the body passage is closed by the auxiliary oil chamber.

Zumindest ein Teil einer Wandung mindestens einer Zusatzölkammer ist separat von dem Grundkörper hergestellt und anschließend mit dem Grundkörper verbunden worden.At least part of a wall of at least one auxiliary oil chamber has been produced separately from the main body and subsequently connected to the main body.

Dabei kann der separat von dem Grundkörper hergestellte Teil der Wandung der Zusatzölkammer eine Deckenwand der Zusatzölkammer und/oder zumindest einen Teil einer vorderen Stirnwand der Zusatzölkammer und/oder zumindest einen Teil einer hinteren Stirnwand der Zusatzölkammer und/oder eine der Durchtrittsöffnung gegenüberliegende Seitenwand der Zusatzölkammer und/oder eine Bodenwand der Zusatzölkammer umfassen.In this case, the part of the wall of the auxiliary oil chamber produced separately from the main body may have a top wall of the auxiliary oil chamber and / or at least part of a front end wall of the auxiliary oil chamber and / or at least part of a rear end wall of the auxiliary oil chamber and / or one of the passage opening opposite side wall of the auxiliary oil chamber and or include a bottom wall of the auxiliary oil chamber.

Insbesondere kann vorgesehen sein, dass die komplette Wandung der Zusatzölkammer separat von dem Grundkörper hergestellt und anschließend mit dem Grundkörper verbunden worden ist.In particular, it can be provided that the complete wall of the auxiliary oil chamber has been manufactured separately from the base body and subsequently connected to the base body.

Die Zusatzölkammer kann stoffschlüssig, beispielsweise durch Klebung oder Schweißung, mit dem Grundkörper verbunden sein.The additional oil chamber can be materially connected, for example by gluing or welding, to the base body.

Als besonders günstig hat es sich erwiesen, wenn die Zusatzölkammer durch Reibschweißung mit dem Grundkörper verbunden ist.It has proved to be particularly favorable when the additional oil chamber is connected by friction welding to the base body.

Die Gestaltung der erfindungsgemäßen Ölwanne wird besonders flexibel, wenn die Wandung des Grundkörpers mindestens zwei Durchtrittsöffnungen aufweist, durch welche jeweils eine Zusatzölkammer mit der Hauptölkammer des Grundkörpers verbunden ist.The design of the oil pan according to the invention is particularly flexible when the wall of the base body has at least two passage openings through which an additional oil chamber is connected to the main oil chamber of the body.

Die Durchtrittsöffnungen können dabei an einander gegenüberliegenden Wandabschnitten der Wandung des Grundkörpers ausgebildet sein.The passages may be formed on opposite wall portions of the wall of the body.

Ferner kann vorgesehen sein, dass die mindestens zwei Zusatzölkammern bezüglich einer Längsmittelebene der Ölwanne im Wesentlichen symmetrisch zueinander ausgebildet sind.Furthermore, it can be provided that the at least two additional oil chambers are formed substantially symmetrically with respect to a longitudinal center plane of the oil pan.

Wenn auch der Grundkörper der Ölwanne im Wesentlichen symmetrisch zu dieser Längsmittelebene ausgebildet ist, so ist in diesem Fall die gesamte Ölwanne im Wesentlichen spiegelsymmetrisch zu ihrer Längsmittelebene ausgebildet.Although the main body of the oil pan is formed substantially symmetrically to this longitudinal center plane, so in this case, the entire oil pan is formed substantially mirror-symmetrical to its longitudinal center plane.

Grundsätzlich kann der Grundkörper der Ölwanne aus einem beliebigen geeigneten Material gebildet sein.Basically, the main body of the oil pan can be formed of any suitable material.

Vorzugsweise ist vorgesehen, dass der Grundkörper der Ölwanne aus einem thermoplastisch verarbeitbaren Kunststoffmaterial, beispielsweise aus Polyamid, gebildet ist.It is preferably provided that the base body of the oil pan is formed from a thermoplastically processable plastic material, for example polyamide.

Auch die mindestens eine Zusatzölkammer kann grundsätzlich aus einem beliebigen geeigneten Material gebildet sein.The at least one additional oil chamber can in principle also be formed from any suitable material.

Vorzugsweise ist zumindest ein Teil einer Wandung mindestens einer Zusatzölkammer aus einem thermoplastisch verarbeitbaren Kunststoffmaterial, beispielsweise aus Polyamid, gebildet.Preferably, at least part of a wall of at least one auxiliary oil chamber is formed from a thermoplastically processable plastic material, for example from polyamide.

Besonders günstig ist es, wenn eine Wandung mindestens einer Zusatzölkammer aus demselben Material gebildet ist wie der Grundkörper der Ölwanne.It is particularly favorable if a wall of at least one auxiliary oil chamber is formed from the same material as the main body of the oil pan.

Die Durchtrittsöffnung, welche durch die Zusatzölkammer verschlossen wird, kann bereits bei der Herstellung des Grundkörpers in die Wandung des Grundkörpers eingeformt sein.The passage opening, which is closed by the auxiliary oil chamber, may already be molded into the wall of the main body during the production of the main body.

Alternativ hierzu kann, insbesondere bei einer nachträglichen Erweiterung einer bestehenden Ölwanne, auch vorgesehen sein, dass der Grundkörper zunächst ohne die Durchtrittsöffnung in seiner Wandung hergestellt wird und dass die mindestens eine Durchtrittsöffnung aus der Wandung des Grundkörpers herausgetrennt, insbesondere herausgeschnitten oder herausgestanzt, ist.Alternatively, it may be provided, in particular in a subsequent extension of an existing oil pan, that the base body is initially made without the passage opening in its wall and that the at least one passage opening cut out of the wall of the body, in particular cut out or punched out is.

Um die Wandung des Grundkörpers der Ölwanne zu versteifen und den Ölfluss im gesamten Ölsammelvolumen der Ölwanne zu beruhigen, kann vorgesehen sein, dass in mindestens einer Durchtrittsöffnung eine Versteifungswand mit mindestens einer Öl-Durchlassöffnung angeordnet ist. Diese Versteifungswand kann auch als Schwallwand zur Beruhigung der Bewegung des Öls in der Ölwanne dienen.In order to stiffen the wall of the main body of the oil pan and to calm the oil flow in the entire oil collection volume of the oil pan, it can be provided that in at least one passage opening a stiffening wall is arranged with at least one oil passage opening. This stiffening wall can also serve as a baffle to calm the movement of the oil in the sump.

Insbesondere kann vorgesehen sein, dass die Versteifungswand mindestens zwei Öl-Durchlassöffnungen aufweist.In particular, it can be provided that the stiffening wall has at least two oil passage openings.

Um die gesamte Bauhöhe der Ölwanne möglichst niedrig zu halten, ist mindestens eine Zusatzölkammer seitlich neben der Hauptölkammer angeordnet.In order to keep the overall height of the oil pan as low as possible, at least one auxiliary oil chamber is arranged laterally next to the main oil chamber.

Insbesondere kann dabei vorgesehen sein, dass die Zusatzölkammer weder nach unten noch nach oben über die Hauptölkammer der Ölwanne übersteht. Mindestens ein Teil einer Wandung mindestens einer Zusatzölkammer ist einstückig mit dem Grundkörper ausgebildet.In particular, it can be provided that the auxiliary oil chamber neither protrudes downwards nor upwards beyond the main oil chamber of the oil sump. At least part of a wall of at least one auxiliary oil chamber is integrally formed with the main body.

Dabei umfasst der einstückig mit dem Grundkörper ausgebildete Teil der Wandung der Zusatzölkammer eine Bodenwand der Zusatzölkammer und kann zumindest einen Teil einer vorderen Stirnwand der Zusatzölkammer und/oder zumindest einen Teil einer hinteren Stirnwand der Zusatzölkammer und/oder eine der Durchtrittsöffnung gegenüberliegende Seitenwand der Zusatzölkammer umfassen.In this case, the integrally formed with the main body part of the wall of the auxiliary oil chamber comprises a bottom wall of the auxiliary oil chamber and may comprise at least a portion of a front end wall of the auxiliary oil chamber and / or at least a portion of a rear end wall of the auxiliary oil chamber and / or one of the passage opening opposite side wall of the auxiliary oil chamber.

Bei der erfindungsgemäßen Ölwanne ist vorgesehen, dass zumindest ein Teil einer Wandung mindestens einer Zusatzölkammer separat von dem Grundkörper hergestellt und anschließend mit dem Grundkörper verbunden worden ist, wobei mindestens ein anderer Teil der Wandung dieser Zusatzölkammer einstückig mit dem Grundkörper ausgebildet ist.In the oil sump according to the invention, it is provided that at least one part of a wall of at least one auxiliary oil chamber has been produced separately from the main body and subsequently connected to the main body, wherein at least one other part of the wall of this auxiliary oil chamber is formed integrally with the main body.

Dabei ist es besonders günstig, wenn der separat von dem Grundkörper hergestellte Teil der Wandung eine Deckenwand der Zusatzölkammer umfasst.It is particularly advantageous if the part of the wall produced separately from the main body comprises a top wall of the auxiliary oil chamber.

Vorzugsweise umfasst der separat von dem Grundkörper hergestellte Teil der Wandung nur eine Deckenwand der Zusatzölkammer, da in diesem Fall die Verbindungslinie zwischen dem separat von dem Grundkörper hergestellten Teil der Wandung und dem einstückig mit dem Grundkörper ausgebildeten Teil der Wandung im Wesentlichen vollständig nahe des oberen Endes der Zusatzölkammer verläuft, so dass das in der Zusatzölkammer enthaltene Öl nur selten oder gar nicht diese Verbindungslinie erreicht. Hierdurch wird der Vorteil erzielt, dass die Verbindungslinie zwischen dem separat von dem Grundkörper hergestellten Teil der Wandung und dem einstückig mit dem Grundkörper hergestellten Teil der Wandung nicht oder zumindest nur selten mit dem in der Ölwanne enthaltenen Öl beaufschlagt wird, was sich günstig auf die Langlebigkeit und Zuverlässigkeit der Abdichtung längs der Verbindungslinie auswirkt. Ferner ist es günstig, wenn mindestens ein Anschluss der Ölwanne, dessen Vorhandensein und/oder dessen Position an der Ölwanne in Abhängigkeit von dem Fahrzeugtyp, für welchen die Ölwanne verwendet werden soll, variieren, an einem separat von dem Grundkörper hergestellten Teil der Wandung mindestens einer Zusatzölkammer vorgesehen ist.Preferably, the part of the wall produced separately from the main body comprises only one top wall of the auxiliary oil chamber, since in this case the connecting line between the part of the wall produced separately from the main body and the part of the wall formed integrally with the main body is substantially completely close to the top end the auxiliary oil chamber runs so that the oil contained in the auxiliary oil chamber only rarely or not at all reaches this connection line. In this way, the advantage is achieved that the connecting line between the part of the wall produced separately from the main body and the part of the wall produced integrally with the main body is not or at least rarely subjected to the oil contained in the oil pan, which is beneficial to the longevity and reliability of the seal along the connection line. Furthermore, it is favorable if at least one connection of the oil sump, whose presence and / or position on the sump varies depending on the type of vehicle for which the oil sump is to be used, on a part of the wall produced separately from the main body of at least one Additional oil is provided.

Hierdurch ist es möglich, für verschiedene Fahrzeugtypen ein und denselben Grundkörper der Ölwanne zu verwenden und, in Abhängigkeit vom jeweiligen Fahrzeugtyp, diesen Grundkörper um einen fahrzeugtypabhängigen, separat von dem Grundkörper hergestellten Teil der Wandung mit dem betreffenden Anschluss zu ergänzen.This makes it possible to use one and the same body of the oil pan for different types of vehicles and, depending on the vehicle type, this body to supplement a vehicle type dependent, manufactured separately from the body portion of the wall with the relevant connection.

So kann beispielsweise vorgesehen sein, dass an dem separat von dem Grundkörper hergestellten Teil der Wandung ein Anschluss für eine Öleinfüllleitung vorgesehen ist.For example, it can be provided that a connection for an oil filler line is provided on the part of the wall which is produced separately from the basic body.

Alternativ oder ergänzend hierzu kann vorgesehen sein, dass an dem separat von dem Grundkörper hergestellten Teil der Wandung ein Anschluss für einen Ölfüllstandssensor angeordnet ist.Alternatively or additionally, it may be provided that a connection for an oil level sensor is arranged on the part of the wall which is produced separately from the main body.

Alternativ oder ergänzend hierzu kann ferner vorgesehen sein, dass an dem separat von dem Grundkörper hergestellten Teil der Wandung ein Anschluss für eine Ölpeilstabführung und/oder für eine Ölabsaugleitung angeordnet ist.Alternatively or additionally, it may further be provided that a connection for an oil dipstick guide and / or for an oil suction line is arranged on the part of the wall produced separately from the main body.

Hierbei kann insbesondere vorgesehen sein, dass der Anschluss für eine Ölpeilstabführung und/oder für eine Ölabsaugleitung einen einstückig mit der Wandung ausgebildeten Anschlussstutzen für die Montage eines zumindest teilweise im Innenraum der Zusatzölkammer angeordneten Rohres aufweist.In this case, it can be provided, in particular, that the connection for an oil dipstick guide and / or for an oil suction line has a connecting piece designed in one piece with the wall for mounting a pipe arranged at least partially in the interior of the auxiliary oil chamber.

Dabei kann der Anschlussstutzen mit einer, beispielsweise im Längsschnitt sägezahnförmigen, Profilierung versehen sein, welche sich bei der Montage des Rohres in das an dem Anschlussstutzen zu montierende Rohr eingräbt, so dass nach dem Aufschieben des Rohres auf den Anschlussstutzen (oder nach dem Einschieben des Rohres in den Anschlussstutzen, wenn die Profilierung an einer Innenseite des Anschlussstutzens vorgesehen ist) das Rohr durch Formschluss unverlierbar an dem Anschluss für die Ölpeilstabführung und/oder für die Ölabsaugleitung gehalten ist.In this case, the connecting piece can be provided with a, for example, in longitudinal section sawtooth-shaped profiling, which is during assembly of the pipe digs into the pipe to be mounted on the connecting piece, so that after pushing the pipe onto the connecting piece (or after inserting the pipe into the connecting piece, if the profiling is provided on an inner side of the connecting piece) the pipe by captive on captive the connection for the oil dipstick guide and / or for the oil suction line is held.

Eine in den Fig. 1 und 2 dargestellte, als Ganzes mit 100 bezeichnete Ölwanne umfasst einen wannenförmigen Grundkörper 102, welcher seinerseits zwei einander gegenüberliegende, im Wesentlichen parallel zueinander verlaufende Längsseitenwände 104a, 104b, zwei die Längsseitenwände miteinander verbindende Querseitenwände 106a, 106b, einen von den Längsseitenwände 104a, 104b und den Querseitenwänden 106a, 106b getragenen Montageflansch 108, welcher am oberen Rand der Seitenwände 104a, 104b, 106a und 106b ringförmig umlaufend ausgebildet ist, eine von dem Montageflansch 108 umschlossene Zugangsöffnung 110, einen näher an der Zugangsöffnung 110 angeordneten oberen Bodenabschnitt 112, einen weiter entfernt von der Zugangsöffnung 110 angeordneten unteren Bodenabschnitt 114 und einen den oberen Bodenabschnitt 112 mit dem unteren Bodenabschnitt 114 verbindenden schrägen mittleren Bodenabschnitt 116 umfasst.One in the Fig. 1 and 2 shown, as a whole with 100 designated oil pan comprises a trough-shaped base 102, which in turn two mutually opposite, substantially parallel longitudinal side walls 104a, 104b, the longitudinal side walls interconnecting transverse side walls 106a, 106b, one of the longitudinal side walls 104a, 104b and the transverse side walls 106a, 106b mounted mounting flange 108, which is formed on the upper edge of the side walls 104a, 104b, 106a and 106b annularly surrounding an enclosed by the mounting flange 108 access opening 110, a closer to the access opening 110 arranged upper bottom portion 112, a farther from the Access opening 110 arranged lower bottom portion 114 and a top floor portion 112 with the lower bottom portion 114 connecting inclined middle bottom portion 116 includes.

Die Seitenwände 104a, 104b, 106a und 106b sowie die Bodenabschnitte 112, 114 und 116 umschließen einen Innenraum 117 des Grundkörpers 102, welcher eine Hauptölsammelkammer 119 bildet.The side walls 104a, 104b, 106a and 106b and the bottom portions 112, 114 and 116 enclose an inner space 117 of the main body 102, which forms a main oil collecting chamber 119.

In den einander gegenüberliegenden Längsseitenwänden 104a, 104b sind zwei im Wesentlichen kongruente, miteinander fluchtende Durchtrittsöffnungen 118 ausgebildet.In the opposite longitudinal side walls 104a, 104b, two substantially congruent, mutually aligned through openings 118 are formed.

Der Grundkörper 102 ist aus einem geeigneten thermoplastisch verarbeitbaren Material, beispielsweise aus Polyamid, durch ein Spritzgießverfahren hergestellt.The base body 102 is made of a suitable thermoplastically processable material, for example of polyamide, by an injection molding process.

Dabei werden die Durchtrittsöffnungen 118 durch entsprechende Gestaltung der Spritzgießform bereits bei der Herstellung des Grundkörpers 102 im Spritzgießverfahren in die Wandung des Grundkörpers 102 eingeformt.In this case, the passage openings 118 are formed by appropriate design of the injection mold in the production of the base body 102 by injection molding in the wall of the body 102.

Alternativ hierzu kann auch vorgesehen sein, dass der Grundkörper 102 zunächst in einem Spritzgießverfahren ohne die Durchtrittsöffnungen 118 in seiner Wandung hergestellt wird und die Durchtrittsöffnungen 118 anschließend aus den Längsseitenwänden 104a, 104b herausgetrennt, insbesondere herausgeschnitten oder herausgestanzt, werden.Alternatively, it can also be provided that the base body 102 is first produced in an injection molding process without the passage openings 118 in its wall and the passage openings 118 then cut out of the longitudinal side walls 104a, 104b, in particular cut out or punched out.

Ferner umfasst die Ölwanne 100 zwei im Wesentlichen quaderförmige Zusatzölkammern 120, welche auf ihren dem Grundkörper 102 der Ölwanne 100 zugewandten Seiten jeweils offen sind.Furthermore, the oil pan 100 comprises two substantially parallelepipedic auxiliary oil chambers 120, which are each open on their sides facing the main body 102 of the oil pan 100.

Die Zusatzölkammern 120 werden aus einem thermoplastisch verarbeitbaren Kunststoffmaterial, beispielsweise aus Polyamid, in einem Spritzgießverfahren hergestellt.The additional oil chambers 120 are made of a thermoplastically processable plastic material, for example of polyamide, in an injection molding process.

Insbesondere können die Zusatzölkammern 120 aus demselben thermoplastisch verformbaren Kunststoffmaterial hergestellt sein wie der Grundkörper 102.In particular, the auxiliary oil chambers 120 may be made of the same thermoplastically deformable plastic material as the main body 102.

Die Zusatzölkammern 120 werden jeweils so auf die Außenseite der jeweils zugeordneten Längsseitenwand 104a bzw. 104b aufgesetzt, dass sie die in der jeweiligen Längsseitenwand 104a, 104b angeordnete Durchtrittsöffnung 118 umschließen und seitliche Backen an der Wandung des Grundkörpers 102 bilden.The additional oil chambers 120 are respectively placed on the outside of the respective associated longitudinal side wall 104a and 104b, that they surround the passage opening 118 arranged in the respective longitudinal side wall 104a, 104b and form lateral jaws on the wall of the base body 102.

Anschließend werden die Zusatzölkammern 120 stoffschlüssig mit dem Grundkörper 102 verbunden, beispielsweise durch Reibschweißen längs eines umlaufenden Reibschweißrandes 123.Subsequently, the additional oil chambers 120 are materially connected to the base body 102, for example by friction welding along a peripheral Reibschweißrandes 123rd

Die auf diese Weise aus dem Grundkörper 102 und den beiden Zusatzölkammern 120 zusammengesetzte Ölwanne 100 weist aufgrund der Zusatzölkammern 120 ein größeres Ölsammelvolumen auf als eine Ölwanne, welche lediglich aus dem Grundkörper 102 (ohne die Durchtrittsöffnungen 118) gebildet wäre.The composite in this way from the main body 102 and the two auxiliary oil chambers 120 oil pan 100 has due to the additional oil chambers 120 a larger oil collection volume than an oil pan, which would be formed only from the main body 102 (without the passage openings 118).

Durch geeignete Wahl der Größe der Zusatzölkammern 120 kann das Gesamt-Ölsammelvolumen der Ölwanne 100 an jeden beliebigen Anwendungsfall angepasst werden, ohne dass hierzu der Grundkörper 102 und insbesondere der Montageflansch 108, über welchen die Ölwanne 100 mit einem Verbrennungsmotor verbunden wird, modifiziert werden muss.By suitable choice of the size of the additional oil chambers 120, the total oil collection volume of the oil pan 100 can be adapted to any application, without requiring the base body 102 and in particular the mounting flange 108, via which the oil pan 100 is connected to an internal combustion engine, must be modified.

Vorzugsweise sind die Zusatzölkammern 120 spiegelsymmetrisch zueinander ausgebildet, so dass die gesamte Ölwanne 100 im Wesentlichen spiegelsymmetrisch zu ihrer in der Längsrichtung 122 des Grundkörpers 102 verlaufenden vertikalen Längsmittelebene ausgebildet ist.Preferably, the auxiliary oil chambers 120 are mirror-symmetrical to each other, so that the entire oil pan 100 is formed substantially mirror-symmetrical to its longitudinal direction in the longitudinal direction 122 of the main body 102 extending vertical longitudinal center plane.

Die Wandung 124 jeder Zusatzölkammer 120 umfasst eine Deckenwand 126, eine vordere Stirnwand 128, eine der vorderen Stirnwand 128 gegenüberliegende hintere Stirnwand 130, eine die beiden Stirnwände 128 und 130 miteinander verbindende, der Durchtrittsöffnung 118 gegenüberliegende Seitenwand 132 und eine Bodenwand 133.The wall 124 of each auxiliary oil chamber 120 comprises a top wall 126, a front end wall 128, a rear end wall 130 opposite the front end wall 128, a side wall 132 connecting the two end walls 128 and 130, the passage opening 118 opposite, and a bottom wall 133.

Bei der in den Fig. 1 und 2 dargestellten ersten Ausführungsform einer Ölwanne 100 ist die Wandung 124 jeder Zusatzölkammer 120 einstückig ausgebildet, separat von dem Grundkörper 102 hergestellt und anschließend mit dem Grundkörper 102 verbunden.In the in the Fig. 1 and 2 illustrated first embodiment of an oil pan 100, the wall 124 of each auxiliary oil chamber 120 is integrally formed, made separately from the base body 102 and then connected to the main body 102.

Eine in Fig. 3 dargestellte zweite Ausführungsform einer Ölwanne 100 unterscheidet sich von der in den Fig. 1 und 2 dargestellten ersten Ausführungsform dadurch, dass die Durchtrittsöffnungen 118 in den Längs-Seitenwänden 104a, 104b des Grundkörpers 102 jeweils durch eine Versteifungswand 134 verschlossen sind, wobei in jeder Versteifungswand 134 mindestens eine Öl-Durchlassöffnung 136, vorzugsweise mehrere solcher Öl-Durchlassöffnungen 136, insbesondere zwei solcher Öl-Durchlassöffnungen 136, vorgesehen sind, um das Ölsammelvolumen in der jeweils zugeordneten Zusatzölkammer 120 mit dem Ölsammelvolumen der Hauptölsammelkammer 119 im Innenraum 117 des Grundkörpers 102 zu verbinden.An in Fig. 3 illustrated second embodiment of an oil pan 100 differs from that in the Fig. 1 and 2 illustrated in that the passage openings 118 in the longitudinal side walls 104a, 104b of the base body 102 are each closed by a stiffening wall 134, wherein in each stiffening wall 134 at least one oil passage opening 136, preferably a plurality of such oil passage openings 136, in particular two such oil passage openings 136 are provided to connect the oil collecting volume in the respective associated auxiliary oil chamber 120 with the oil collecting volume of the main oil collecting chamber 119 in the inner space 117 of the main body 102.

Die Versteifungswände 134 dienen zur Versteifung der jeweiligen Längs-Seitenwand 104a bzw. 104b des Grundkörpers 102 und zur Beruhigung des Ölflusses im gesamten Ölsammelvolumen der Ölwanne 100.The stiffening walls 134 serve to stiffen the respective longitudinal side wall 104a or 104b of the main body 102 and to calm the oil flow in the entire oil collecting volume of the oil pan 100th

Im Übrigen stimmt die in Fig. 3 dargestellte zweite Ausführungsform einer Ölwanne 100 hinsichtlich Aufbau, Funktion und Herstellungsweise mit der in den Fig. 1 und 2 dargestellten ersten Ausführungsform überein, auf deren vorstehende Beschreibung insoweit Bezug genommen wird.Incidentally, the in Fig. 3 illustrated second embodiment of an oil pan 100 in terms of structure, function and method of manufacture with in the Fig. 1 and 2 illustrated in the first embodiment, reference is made to the above description in this regard.

Eine in den Fig. 4 und 5 dargestellte dritte Ausführungsform einer Ölwanne 100 unterscheidet sich von der in Fig. 3 dargestellten zweiten Ausführungsform dadurch, dass die Wandung 124 jeder Zusatzölkammer 120 nicht einstückig ausgebildet ist, sondern die Wandung 124 jeweils aus einem einstückig mit dem Grundkörper 102 ausgebildeten ersten Wandungsteil 138 und einem hierzu komplementären, separat von dem Grundkörper 102 hergestellten und anschließend mit dem ersten Wandungsteil 138 verbundenen zweiten Wandungsteil 140 zusammengesetzt ist.One in the Fig. 4 and 5 illustrated third embodiment of an oil pan 100 differs from the in Fig. 3 illustrated second embodiment in that the wall 124 of each auxiliary oil chamber 120 is not formed integrally, but the wall 124 each made of a integrally formed with the base 102 first wall portion 138 and a complementary thereto, manufactured separately from the base 102 and then with the first wall part 138 connected second wall portion 140 is composed.

Dabei umfasst das einstückig mit dem Grundkörper 102 ausgebildete erste Wandungsteil 138 die Bodenwand 133 sowie die an die Bodenwand 133 und an die Längs-Seitenwand 104a bzw. 104b des Grundkörpers 102 angrenzende Hälfte 142 der vorderen Stirnwand 128 sowie die entsprechende Hälfte 144 der hinteren Stirnwand 144 der Wandung 124 der jeweiligen Zusatzölkammer 120, während das separat vom Grundkörper 102 hergestellte zweite Wandungsteil 140 die Deckenwand 126, die Seitenwand 132, die an die Deckenwand 126 und die Seitenwand 132 angrenzende Hälfte 146 der vorderen Stirnwand 128 und die entsprechende Hälfte 148 der hinteren Stirnwand 130 umfasst.In this case, the first wall part 138 formed integrally with the base body 102 comprises the bottom wall 133 and the half 142 of the front end wall 128 adjoining the bottom wall 133 and the longitudinal side wall 104a or 104b of the base body 102 and the corresponding half 144 the rear end wall 144 of the wall 124 of the respective auxiliary oil chamber 120, while the second wall portion 140 produced separately from the base body 102, the ceiling wall 126, the side wall 132, which is adjacent to the top wall 126 and the side wall 132 half 146 of the front end wall 128 and the corresponding half 148 includes the rear end wall 130.

Der Grundkörper 102 ist zusammen mit den ersten Wandungsteilen 138 aus einem geeigneten thermoplastisch verarbeitbaren Material, beispielsweise aus Polyamid, durch ein Spritzgießverfahren hergestellt.The main body 102 is made together with the first wall parts 138 of a suitable thermoplastically processable material, for example of polyamide, by an injection molding process.

Die zweiten Wandungsteile 140 werden aus einem thermoplastisch verarbeitbaren Kunststoffmaterial, beispielsweise aus Polyamid, in einem Spritzgießverfahren hergestellt.The second wall parts 140 are made of a thermoplastically processable plastic material, for example of polyamide, in an injection molding process.

Insbesondere können die zweiten Wandungsteil 140 aus demselben thermoplastisch verformbaren Kunststoffmaterial hergestellt sein wie der Grundkörper 102 mit den ersten Wandungsteilen 138.In particular, the second wall part 140 may be made of the same thermoplastically deformable plastic material as the main body 102 with the first wall parts 138.

Die zweiten Wandungsteile 140 werden jeweils so auf die Außenseite der jeweils zugeordneten Längsseitenwand 104a bzw. 104b und auf den Rand des jeweils zugeordneten ersten Wandungsteils 138 aufgesetzt, dass sie das jeweilige erste Wandungsteil 138 zu einer vollständigen Zusatzölkammer 120 ergänzen und gemeinsam mit dem jeweiligen ersten Wandungsteil 138 seitliche Backen an der Wandung des Grundkörpers 102 bilden.The second wall parts 140 are respectively placed on the outside of the respective associated longitudinal side wall 104a and 104b and on the edge of the respectively associated first wall portion 138 that they complement the respective first wall portion 138 to a complete auxiliary oil chamber 120 and together with the respective first wall portion 138 side jaws on the wall of the body 102 form.

Anschließend werden die zweiten Wandungsteile 140 der Zusatzölkammern 120 stoffschlüssig mit dem Grundkörper 102 und mit den ersten Wandungsteilen 138 verbunden, beispielsweise durch Reibschweißen.Subsequently, the second wall parts 140 of the auxiliary oil chambers 120 are materially connected to the base body 102 and to the first wall parts 138, for example by friction welding.
