Description
Die Erfindung betrifft eine Ölwanne für eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an oil pan for an internal combustion engine according to the preamble of claim 1.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Ölwanne mit einer besonders zuverlässigen und guten Abdichtung gegenüber jenem Gehäuseteil bzw. jenen Gehäuseteilen zu schaffen, an dem bzw. an denen die Ölwanne befestigt ist.Object of the present invention is to provide an oil pan with a particularly reliable and good seal against that housing part or those housing parts on which or to which the oil pan is attached.
Diese Aufgabe wird durch eine Ölwanne mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in Unteransprüchen angegeben. Weitere wichtige Merkmale der Erfindung sind in der nachfolgenden Beschreibung aufgeführt und/oder in der Zeichnung gezeigt. Dabei können die Merkmale in ganz unterschiedlichen Kombinationen für die Erfindung wesentlich sein, ohne dass hierauf jeweils explizit hingewiesen wird.This object is achieved by an oil pan having the features of claim 1. Advantageous developments are specified in subclaims. Other important features of the invention are set forth in the following description and / or shown in the drawing. The features in very different combinations for the invention may be essential, without being explicitly noted.
Durch die erfindungsgemäß vorgesehene doppelschalige Ausgestaltung der Ölwanne mindestens an deren Dichtbereich wird die Steifigkeit der Ölwanne erheblich erhöht. Damit ist auch in zwischen den Verschraubungspunkten der Ölwanne mit dem Kurbelgehäuse oder dem Getriebegehäuse liegenden Bereichen eine ausreichende Anpresskraft vorhanden, welche für eine zuverlässige und dauerhafte Abdichtung erforderlich ist. Darüber hinaus kann die Ölwanne ohne Steifigkeitsverlust zumindest bereichsweise flacher als bisher ausgeführt werden, was einen Zugewinn an Bauraum und, bspw. im Falle eines Kraftfahrzeugs, an Bodenfreiheit ermöglicht. Die Steifigkeit wird nochmals deutlich erhöht, indem die Ölwanne mindestens einen zwischen gegenüberliegenden Dichtbereichen angeordneten Steg oder Zapfen umfasst, der das Stabilisierungsteil mit dem Bodenabschnitt zusätzlich verbindet. Damit wird einem festigkeitsmindernden Beulen des Stabilisierungsteils und auch des Bodenabschnitts entgegengewirkt, und auch Geräusch verursachende Vibrationen des Stabilisierungsteils sowie des Bodenabschnitts werden vermindert.By inventively provided double-shell design of the oil pan at least at the sealing area, the rigidity of the oil pan is significantly increased. Thus, even in between the Verschraubungspunkten the oil pan with the crankcase or the transmission housing areas sufficient contact pressure exists, which is required for a reliable and durable seal. In addition, the oil pan without loss of rigidity at least partially flatter than previously executed, which allows an increase in space and, for example. In the case of a motor vehicle, ground clearance. The rigidity is again significantly increased by the oil pan comprises at least one arranged between opposite sealing portions web or pin, which additionally connects the stabilizing part with the bottom portion. This counteracts a strength-reducing bulging of the stabilization part and also of the bottom section, and also noise-causing vibrations of the stabilization part and of the bottom section are reduced.
Dabei wird die Herstellung vereinfacht, wenn der Dichtbereich eine Schulter aufweist, an der das Stabilisierungsteil befestigt ist.In this case, the production is simplified if the sealing region has a shoulder to which the stabilizing part is attached.
Ein besonders günstiger Kraftschluss zwischen Stabilisierungsteil und Bodenabschnitt wird geschaffen, wenn der Dichtbereich eine Nut aufweist, in die das Stabilisierungsteil eingreift.A particularly favorable frictional connection between the stabilizing part and the bottom section is created when the sealing region has a groove into which the stabilizing part engages.
Grundsätzlich kann das Stabilisierungsteil jedoch auch stumpf am Dichtbereich befestigt werden. In diesem Fall sind am Dichtbereich selbst keine Veränderungen erforderlich.In principle, however, the stabilization part can also be attached to the sealing area in a blunt manner. In this case, no changes are required at the sealing area itself.
Der Dichtbereich kann auch am Stabilisierungsteil angeordnet sein, wobei dann jedoch auf eine gute Abdichtung durch eine entsprechende Verbindung des Stabilisierungsteils mit dem Bodenabschnitt geachtet werden muss.The sealing region can also be arranged on the stabilizing part, wherein, however, attention must then be paid to a good sealing by a corresponding connection of the stabilizing part to the bottom section.
Der Steg und/oder Zapfen kann an das Stabilisierungsteil oder an den Bodenabschnitt angeformt sein. Damit wird entweder die Herstellung des Stabilisierungsteils oder des Bodenabschnitts der Ölwanne vereinfacht.The web and / or pin may be integrally formed on the stabilizing part or on the bottom portion. Thus, either the production of the stabilizing part or the bottom portion of the oil pan is simplified.
Vorteilhaft ist es ferner, wenn mindestens ein Abschnitt eines Stegs gegenüber einer Längsachse der Ölwanne in einem Winkel verläuft, der größer als Null und kleiner als 90° ist. Damit erhält der Steg neben seiner Verbindungsfunktion eine Ölführ- und Beruhigungsfunktion. Diese ist dann besonders wirkungsvoll, wenn mehrere Stege zueinander verschachtelt angeordnet sind.It is also advantageous if at least a portion of a web extends with respect to a longitudinal axis of the oil pan at an angle which is greater than zero and less than 90 °. This gives the bridge in addition to its connection function Ölführ- and reassurance. This is particularly effective when a plurality of webs are arranged interleaved with each other.
In dem Stabilisierungsteil können Ölberuhigungskanäle vorhanden sein, die von einer Oberseite des Stabilisierungsteils in einen Raum zwischen Stabilisierungsteil und Bodenabschnitt führen. Damit erhält das Stabilisierungsteil eine zusätzliche Ölberuhigungsfunktion. Deren Wirkung wird nochmals verbessert, wenn mindestens ein Ölberuhigungskanal abschnittsweise in einem Steg verläuft, denn hierdurch wird der Ölberuhigungskanal verlängert.In the stabilizing part there may be oil calming passages extending from an upper side of the stabilizing part into a space between Stabilization and ground section lead. This gives the stabilizing part an additional oil calming function. Their effect is further improved if at least one oil calming channel runs in sections in a web, because this extends the oil calming channel.
Eine Weiterbildung der erfindungsgemäßen Ölwanne besteht darin, dass mindestens ein Teil eines Ölsaugrohrs mit dem Stabilisierungsteil einstückig ist. Damit erhält das Stabilisierungsteil eine weitere Funktion, nämlich die Halterung bzw. Aufnahme eines Ölsaugrohrs. Dies hat auch Vorteile bei der Herstellung der Ölwanne, da die separate Handhabung mindestens dieses Teils des Ölsaugrohrs entfällt.A development of the oil sump according to the invention is that at least part of an oil suction pipe is integral with the stabilizing part. Thus, the stabilizing part receives another function, namely the holder or receiving a Ölsaugrohrs. This also has advantages in the manufacture of the oil pan, since the separate handling of at least this part of the Ölsaugrohrs deleted.
Mindestens ein Teil eines Ölsaugrohrs kann auch in einem Steg verlaufen. Auch dies reduziert die Anzahl der handzuhabenden Teile bei der Montage der erfindungsgemäßen Ölwanne.At least a part of an oil suction pipe can also run in a web. This also reduces the number of parts to be handled during assembly of the oil pan according to the invention.
Für die Verbindung des Stabilisierungsteils mit dem Bodenabschnitt kommt vor allem eine Verschweißung oder Verklebung in Frage. Hierdurch wird eine dauerhafte und feste Verbindung realisiert. Denkbar ist aber auch eine Verbindung des Stabilisierungsteils mit dem Bodenabschnitt durch eine Rast- oder Schnapp- oder Hakverbindung. Solche Verbindungen sind schnell realisierbar, vereinfachen also die Herstellung der erfindungsgemäßen Ölwanne.For the connection of the stabilization part with the bottom portion, especially a welding or gluing in question. As a result, a permanent and solid connection is realized. However, it is also conceivable to connect the stabilizing part to the bottom section by means of a latching or snap-action or hooking connection. Such compounds can be realized quickly, thus simplifying the production of the oil sump according to the invention.
Eine exakte Positionierung des Stabilisierungsteils gegenüber dem Bodenabschnitt wird erreicht, wenn die Verbindung des Stabilisierungsteils mit dem Bodenabschnitt eine Nut-Feder-Verbindung umfasst.An exact positioning of the stabilizing part relative to the bottom portion is achieved when the connection of the stabilizing part with the bottom portion comprises a tongue and groove connection.
Die Steifigkeit des Stabilisierungsteils wird erhöht, wenn dieses mindestens abschnittsweise eine Zick-Zack-Faltung und/oder Wellenform aufweist. Auch der Ölstrom kann so in einer gewünschten Weise beeinflusst werden.The rigidity of the stabilization part is increased if it has a zig-zag folding and / or waveform at least in sections. Also, the flow of oil can be influenced in a desired manner.
Zwischen dem Stabilisierungsteil und dem Bodenabschnitt kann ein Füllteil angeordnet sein, welches eine Zick-Zack-Faltung und/oder Wellenform aufweist oder aus einem porösen Material hergestellt ist. Durch ein solches Füllteil wird ebenfalls ein Beulen des Bodenabschnitts und/oder des Stabilisierungsteils verhindert oder zumindest erschwert und so die Festigkeit der Ölwanne erhöht.Between the stabilizing part and the bottom portion may be arranged a filling part which has a zig-zag fold and / or wave shape or is made of a porous material. Such a filling part likewise prevents or at least impedes buckling of the bottom section and / or the stabilizing part and thus increases the strength of the oil sump.
Übliche Ölwannen weisen einen flachen Abschnitt und einen tiefen Abschnitt auf. Im Zusammenhang mit dem erfindungsgemäß vorgesehenen Stabilisierungsteil wird daher vorgeschlagen, dass dieses am Dichtbereich des flachen Abschnitts befestigt ist und über den flachen Abschnitt hinaus bis über oder in den tiefen Abschnitt ragt. Damit wird durch das Stabilisierungsteil vor allem der zunächst eine aufgrund seiner Flachheit nur eine geringe Steifigkeit aufweisende flache Abschnitt versteift, gleichzeitig der tiefe Abschnitt jedoch durch das Stabilisierungsteil zumindest zum Teil abgedeckt.Common oil pans have a flat section and a deep section. In connection with the stabilizing part provided according to the invention, it is therefore proposed that this is fastened to the sealing region of the flat section and protrudes beyond the flat section beyond or into the deep section. Thus, by the stabilizing part, first of all, a flat section having only a low rigidity due to its flatness is stiffened, but at the same time the deep section is at least partially covered by the stabilizing part.
In diesem Zusammenhang ist es besonders vorteilhaft, wenn der bis über oder in den tiefen Abschnitt ragende Bereich des Stabilisierungsteils zur Halterung mindestens eines Funktionselements, bspw. eines Ölsaugrohrs und/oder eines Ölfilters, dient. Damit kommt dem Stabilisierungsteil eine zusätzliche Funktion zu, und es kann auf eine separate Halterung des Ölsaugrohrs und/oder des Ölfilters verzichtet werden. Dies erleichtert die Handhabung bei der Montage bei der Ölwanne und reduziert so die Herstellkosten.In this context, it is particularly advantageous if the area of the stabilizing part projecting beyond or into the deep section serves for holding at least one functional element, for example an oil suction pipe and / or an oil filter. Thus, the stabilizing part has an additional function, and it can be dispensed with a separate support of the Ölsaugrohrs and / or the oil filter. This facilitates handling during assembly in the oil pan and thus reduces the manufacturing costs.
Besonders vorteilhaft ist es, wenn die Ölwanne einen Ölhobel umfasst, der mindestens zum Teil durch das Stabilisierungsteil gebildet wird. Damit erfüllt das Stabilisierungsteil eine weitere Zusatzfunktion, so dass auf ein entsprechendes separates Teil verzichtet werden kann, was die Handhabung bei der Montage der Ölwanne vereinfacht.It is particularly advantageous if the oil sump comprises an oil planer, which is formed at least in part by the stabilizing part. Thus, the stabilizing part fulfills a further additional function, so that it is possible to dispense with a corresponding separate part, which simplifies handling during assembly of the oil sump.
Vorgeschlagen wird auch, dass die Ölwanne einen Ölhobel umfasst, der mindestens zum Teil durch ein in Einbaulage im Bereich des tiefen Abschnitts der Ölwanne angeordnetes Teil gebildet wird, welches in Einbaulage am Kurbelgehäuse oder einem entsprechenden Gehäuse befestigt ist. Auch dies dient zur Vereinfachung bei der Montage der erfindungsgemäßen Ölwanne.It is also proposed that the oil pan comprises an oil planer, which is at least partially formed by a arranged in the installed position in the region of the deep portion of the oil pan part, which is mounted in the installed position on the crankcase or a corresponding housing. This also serves to simplify the assembly of the oil pan according to the invention.
In Weiterbildung hierzu wird vorgeschlagen, dass an dem im Bereich des tiefen Abschnitts der Ölwanne angeordneten Teil des Ölhobels ein Abschnitt eines Ölsaugrohrs und/oder eines Ölfilters befestigt oder einstückig angeformt ist. Der Ölhobel erhält damit eine zusätzliche Funktion, nämlich die Halterung eines Ölsaugrohrs oder eines Ölfilters. Damit entfallen separat handzuhabende Teile, was die Herstellung der Ölwanne vereinfacht und billiger macht.In a further development, it is proposed that a portion of an oil suction pipe and / or an oil filter is attached to or integrally formed on the part of the oil planer arranged in the region of the deep portion of the oil pan. The oil planer thus receives an additional function, namely the mounting of a Ölsaugrohrs or an oil filter. This eliminates parts to be handled separately, which makes the manufacture of the oil pan easier and cheaper.
