Description

Die Erfindung betrifft eine Schottwandkonstruktion für eine Flüssigkeitsauffangvorrichtung für eine eine Kurbelwelle und Pleuel umfassende Fahrzeugkonstruktion, vorzugsweise eine Verbrennungskraftmaschine (z. B. ein Verbrennungsmotor). Die Erfindung betrifft ebenfalls eine zugehörige Flüssigkeitsauffangvorrichtung.The invention relates to a bulkhead construction for a fluid collecting device for a vehicle construction comprising a crankshaft and connecting rod, preferably an internal combustion engine (e.g. an internal combustion engine). The invention also relates to an associated liquid collecting device.

Im Stand der Technik sind Öl-Auffangvorrichtungen zur Anordnung unter Kurbelwellen-Pleuel-Konstruktionen in unterschiedlichsten Ausführungsformen bekannt. Nachteilig bei herkömmlichen Öl-Auffangvorrichtungen ist insbesondere, dass sich bei einer Schräglage Öl in Eckbereichen der Öl-Auffangvorrichtungen sammeln kann, mit der Folge, dass ein Saugkorb oberhalb des Ölspiegels des abzusaugenden Öls liegt. Ein weiterer Nachteil bei herkömmlichen Öl-Auffangvorrichtungen ist z. B., dass sie zu relativ starken Ölablagerungen neigen.In the prior art, oil collecting devices for arrangement under crankshaft / connecting rod structures are known in a wide variety of embodiments. A disadvantage of conventional oil collecting devices is, in particular, that in the case of an inclined position, oil can collect in corner areas of the oil collecting devices, with the result that a suction strainer lies above the oil level of the oil to be extracted. Another disadvantage with conventional oil collecting devices is e.g. B. that they tend to have relatively strong oil deposits.

Die EP 1 892 390 A2 offenbart, dass Ölabstreifer Öl von der Kurbelwelle und von den Pleueln abstreifen. Unterhalb des Kurbelgehäuses ist eine Ölwanne angeordnet, die das von den Ölabstreifern abgestreifte Öl aufnimmt. Luft-/Ölabscheider trennen die Luft vom zurückgeführten Öl. Jeder Ölabstreifer ist einteilig mit dem zugehörigen Luft-/Ölabscheider ausgeführt und wird zur Öleinlassöffnung jedes Luft-/Ölabscheiders geführt. Jedem Luft-/Ölabscheider ist eine Ölauslassöffnung zugeordnet, so dass sich die Ölauslassöffnung in jedem Fahrzustand eines Kraftfahrzeugs über einem Ölstand in der Ölwanne befindet.The EP 1 892 390 A2 discloses that oil scrapers strip oil from the crankshaft and connecting rods. An oil pan is arranged below the crankcase and receives the oil scraped off by the oil scrapers. Air / oil separators separate the air from the returned oil. Each oil scraper is made in one piece with the associated air / oil separator and is routed to the oil inlet opening of each air / oil separator. An oil outlet opening is assigned to each air / oil separator, so that the oil outlet opening is above an oil level in the oil pan in every driving state of a motor vehicle.

Die DE 10 2008 060412 A1 betrifft einen Verbrennungsmotor mit einem Kurbelgehäuseoberteil und einem Kurbelgehäuseunterteil. Ein von unten am Kurbelgehäuseunterteil angeflanschter und in das Kurbelgehäuseunterteil ragender Ölhobel ist vorgesehen, welcher eine Wandung für eine durch die Drehung einer Kurbelwelle initiierte Ölnebelwalze bildet und welche zumindest einen hobelartigen Schlitz zum Abscheiden von Öltröpfchen aufweist.The DE 10 2008 060412 A1 relates to an internal combustion engine with an upper crankcase part and a lower crankcase part. An oil plane is provided which is flanged onto the lower crankcase part and protrudes into the lower crankcase part, which forms a wall for an oil mist roller initiated by the rotation of a crankshaft and which has at least one plane-like slot for separating oil droplets.

Die US 6 729 292 B1 offenbart einen Ölabweiser für einen Verbrennungsmotor, der erste und zweite ölabweisende Platten zwischen einer Kurbelwelle und einer Ölwanne aufweist. Um den Bauraum und die Gesamthöhe einer Ölabweisvorrichtung so klein wie möglich zu gestalten, wird vorgeschlagen, die Ölabweisplatten so anzuordnen, dass sie sich über die Länge des Kurbelgehäuses im Abstand voneinander überlappen. Die Längskante der zweiten Ölabweisplatte bildet eine Hauptabstreifkante. Zwischen den Ölabweisplatten sind in ihrem überlappenden Bereich streifenförmige Rippen angeordnet, um das Öl in Richtung einer Ansaugstelle der Ölwanne zu führen.The US 6,729,292 B1 discloses an oil deflector for an internal combustion engine that includes first and second oil deflecting plates between a crankshaft and an oil pan. In order to make the installation space and the total height of an oil deflection device as small as possible, it is proposed to arrange the oil deflection plates so that they overlap at a distance from one another over the length of the crankcase. The longitudinal edge of the second oil deflection plate forms a main wiper edge. Between the oil deflection plates are in Arranged their overlapping area strip-shaped ribs to guide the oil in the direction of a suction point of the oil pan.

Die JP 2010 151011 offenbart eine Prallplatte eines Motors für ein Fahrzeug, die zwischen einer Kurbelwelle und einer Ölwanne angeordnet ist. Die Prallplatte besteht aus einer Bodenplatte, Seitenwänden und Flanschteilen, die sich von den oberen Enden der Seitenwände zu den beiden Seiten erstrecken. An jeder der Seitenwände sind Öltropfenlöcher als Öffnungen zur Verbindung eines oberen Raumes mit einem unteren Raum der Prallplatte ausgebildet.Die EP 0 140 108 A1 offenbart, dass zwischen der Kurbelwelle und dem Boden der Ölwanne ein Einsatz angeordnet ist. Durch den Einsatz wird verhindert, dass die durch die Drehung der Kurbelwelle in Rotation versetzte Luft Öl aus der Ölwanne in Wellendrehrichtung bis in den Bewegungsbereich der Pleuel und der Kurbelwangen verdrängt. Andererseits kann das aus den Wellenlagern austretende Spritzöl außerhalb des Einsatzes direkt und im Bereich des Einsatzes über die Vertiefungen in die Ölwanne gelangen. Durch die Seitenwände der Vertiefungen wird ein Übertreten von Spritzöl in den Bewegungsbereich der Kurbelwangen oder Pleuel bzw. Pleuelköpfe weitgehend vermieden.The JP 2010 151011 discloses an engine baffle for a vehicle disposed between a crankshaft and an oil pan. The baffle plate consists of a bottom plate, side walls and flange parts which extend from the upper ends of the side walls to the two sides. On each of the side walls, oil drop holes are formed as openings for connecting an upper space with a lower space of the baffle plate EP 0 140 108 A1 discloses that an insert is disposed between the crankshaft and the bottom of the oil pan. This prevents the air set in rotation by the rotation of the crankshaft from displacing oil from the oil pan in the direction of rotation of the shaft into the range of motion of the connecting rods and the crank webs. On the other hand, the spray oil escaping from the shaft bearings can get into the oil pan directly outside the insert and in the area of the insert via the depressions. The side walls of the depressions largely prevent spray oil from entering the area of movement of the crank webs or connecting rods or connecting rod heads.

Daraus folgt insbesondere, dass in der Schottwandkonstruktion, zweckmäßig mittels der Ausformungen, die Hüllgeometrie einer Kurbelwellenrotationsbewegung abgebildet wird. Das Abbild wird mit einem definierten Abstand derart gestaltet, sodass der Abstand den Spalt ausbilden kann.It follows from this in particular that the envelope geometry of a crankshaft rotational movement is mapped in the bulkhead construction, expediently by means of the formations. The image is designed with a defined spacing in such a way that the spacing can form the gap.

Die Flüssigkeit ist vorzugsweise Öl.The liquid is preferably oil.

Die Flüssigkeit aus den Ausformungen wird vorzugsweise durch die sich drehenden Kurbelwellen- und/oder Pleuelabschnitte in die Flüssigkeitskanäle gequetscht bzw. gepumpt.The liquid from the formations is preferably squeezed or pumped into the liquid channels by the rotating crankshaft and / or connecting rod sections.

Die Ausformungen dienen vorzugsweise zur Aufnahme sich drehender Kurbelwellen- und/oder Pleuelabschnitte und alternativ oder ergänzend zur Aufnahme von Flüssigkeit, insbesondere Öl, aus der Fahrzeugkonstruktion.The formations are preferably used to hold rotating crankshaft and / or connecting rod sections and alternatively or additionally to hold liquid, in particular oil, from the vehicle structure.

Die Erfindung ist nicht auf eine Schottwandkonstruktion beschränkt, sondern umfasst auch eine Flüssigkeitsauffangvorrichtung für eine eine Kurbelwelle und Pleuel umfassende Fahrzeugkonstruktion, z. B. eine Verbrennungskraftmaschine, insbesondere ein Dieselmotor, oder eine andere Kolbenmaschine. Die Flüssigkeitsauffangvorrichtung ist mit einer Schottwandkonstruktion wie hierin offenbart versehen.The invention is not limited to a bulkhead construction, but also comprises a liquid collecting device for a vehicle construction comprising a crankshaft and connecting rods, e.g. B. an internal combustion engine, in particular a diesel engine, or another piston machine.

Die Flüssigkeitsauffangvorrichtung umfasst vorzugsweise eine Flüssigkeits-Wanne zur Flüssigkeitsaufnahme mit einem z.

B. a liquid suction basket or some other liquid suction device having liquid suction area.

Der Flüssigkeitsabsaugbereich ist vorzugsweise im Wesentlichen in der Mitte der Flüssigkeits-Wanne angeordnet. Zur Mitte wird zweckmäßig deswegen gefördert, weil sich hier der Flüssigkeitsabsaugbereich befindet, insbesondere mit der Flüssigkeitsabsaugeinrichtung (Flüssigkeitsabsaugkorb). Die Flüssigkeitsabsaugeinrichtung hat ständig und somit bei quasi jeder Schräglage unter dem Flüssigkeitsspiegel des Flüssigkeitsabsaugbereichs zu liegen, da ansonsten Luft in den Flüssigkeitskreislauf gesaugt würde und somit z. B. eine Motorschmierung nicht mehr oder zumindest nicht mehr sachgemäß gewährleistet werden könnte. Die Flüssigkeitsauffangvorrichtung kann ferner eine Pumpeneinrichtung zum Absaugen der Flüssigkeit aus dem Flüssigkeitsabsaugbereich aufweisen, insbesondere mittels der Flüssigkeitsabsaugeinrichtung.The liquid suction area is preferably arranged essentially in the middle of the liquid tub. It is advisable to convey to the middle because the liquid suction area is located here, in particular with the liquid suction device (liquid suction basket). The liquid suction device has to lie under the liquid level of the liquid suction area at virtually every inclined position, since otherwise air would be sucked into the liquid circuit and thus z. B. an engine lubrication could no longer or at least no longer be guaranteed properly. The liquid collecting device can also have a pump device for sucking off the liquid from the liquid suction area, in particular by means of the liquid suction device.

Zu erwähnen ist, dass die Fahrzeugkonstruktion vorzugsweise einen z. B. stehenden Verbrennungsmotor, insbesondere Dieselmotor, umfasst.

Die Schottwandkonstruktion umfasst mehrere Ausformungen, z. B. zumindest vier, zumindest fünf oder zumindest sechs Ausformungen, wobei zweckmäßig jeweils eine Ausformung für jeweils einen sich drehenden Kurbelwellen- und/oder Pleuelabschnitt ausgeführt ist.The bulkhead construction includes several formations, e.g. B. at least four, at least five, or at least six formations, one formation being expediently designed for each rotating crankshaft and / or connecting rod section.

Figur 1 zeigt eine Flüssigkeitsauffangvorrichtung F mit einer Schottwandkonstruktion 1 für eine eine Kurbelwelle 2 und Pleuel 3.1 bis 3.6 umfassende Fahrzeugkonstruktion V. Die Flüssigkeitsauffangvorrichtung F ist insbesondere eine Ölauffangvorrichtung F, so dass die Figuren nachfolgend unter Bezugnahme auf Öl als Flüssigkeit beschrieben werden, die Erfindung hierauf aber nicht eingeschränkt ist. Figure 1 shows a liquid collecting device F with a bulkhead construction 1 for a vehicle construction V comprising a crankshaft 2 and connecting rods 3.1 to 3.6. The liquid collecting device F is in particular an oil collecting device F, so that the figures are described below with reference to oil as a liquid, but not the invention is restricted.

Die Schottwandkonstruktion 1 ist als Deckeleinrichtung für die Ölauffangvorrichtung F ausgeführt und unter der Kurbelwelle 2 und den Pleuel 3.1 bis 3.6 angeordnet.The bulkhead construction 1 is designed as a cover device for the oil collecting device F and is arranged under the crankshaft 2 and the connecting rods 3.1 to 3.6.

Die Ölauffangvorrichtung F umfasst unter der Schottwandkonstruktion 1 eine Ölwanne 4 zur Aufnahme von Öl aus der Fahrzeugkonstruktion V. Die Ölwanne 4 umfasst einen Ölabsaugbereich 5, aus dem Öl über eine Ölpumpe 6 mittels eines im Ölabsaugbereich 5 angeordneten Ölsaugkorbs abgepumpt werden kann.The oil collecting device F comprises an oil pan 4 under the bulkhead structure 1 for receiving oil from the vehicle structure V. The oil pan 4 comprises an oil suction area 5, from which oil can be pumped out via an oil pump 6 by means of an oil suction basket arranged in the oil suction area 5.

Die Schottwandkonstruktion 1 ist aus zwei separaten Schottwandelementen ausgeführt, in Figur 1 einem linken Schottwandelement und einem rechten Schottwandelement. Die Schottwandelemente sind vorzugsweise symmetrisch zueinander ausgeführt.The bulkhead construction 1 is made of two separate bulkhead elements, in Figure 1 a left bulkhead panel and a right bulkhead panel. The bulkhead elements are preferably designed symmetrically to one another.

Die Schottwandkonstruktion 1 umfasst mehrere Ölkanäle K1, K2, K3, K4, K5 und K6 und mehrere Ausformungen A1, A2, A3, A4, A5 und A6 für sich drehende, zweckmäßig untere, insbesondere unterste Kurbelwellen- und/oder Pleuelabschnitte. Pro Pleuel 3.1 bis 3.6 und somit pro Kurbelwellen- und/oder Pleuelabschnitt ist jeweils eine Ausformung A1 bis A6 vorgesehen.The bulkhead construction 1 comprises several oil channels K1, K2, K3, K4, K5 and K6 and several formations A1, A2, A3, A4, A5 and A6 for rotating, suitably lower, in particular lowermost crankshaft and / or connecting rod sections. One formation A1 to A6 is provided for each connecting rod 3.1 to 3.6 and thus per crankshaft and / or connecting rod section.

Die Ausformungen A1 bis A6 sind so ausgeformt, dass mittels der Drehbewegung der Kurbelwellen- und/oder Pleuelabschnitte Öl aus den Ausformungen A1 bis A6 in die Flüssigkeitskanäle K1 bis K6 beaufschlagt wird, so dass eine Ölförderung von Ausformung zu Ausformung hin zum Ölabsaugbereich 5 erzielt wird.The formations A1 to A6 are shaped in such a way that, by means of the rotary movement of the crankshaft and / or connecting rod sections, oil is applied from the formations A1 to A6 into the liquid channels K1 to K6, so that oil is conveyed from formation to formation to the oil suction area 5 .

Insbesondere wird Öl aus der Ausformung A1 über den Flüssigkeitskanal K1 zur Ausformung A2 beaufschlagt, Öl aus der Ausformung A2 über den Flüssigkeitskanal K2 zur Ausformung A3 beaufschlagt und Öl aus der Ausformung A3 über den Flüssigkeitskanal K3 hin zum Ölabsaugbereich 5 befördert.In particular, oil is applied from the formation A1 via the liquid channel K1 to the formation A2, oil from the formation A2 via the liquid channel K2 to the formation A3 is applied and oil is conveyed from the recess A3 via the liquid channel K3 to the oil suction area 5.

Insbesondere wird Öl aus der Ausformung A6 über den Flüssigkeitskanal K6 zur Ausformung A5 beaufschlagt, Öl aus der Ausformung A5 über den Flüssigkeitskanal K5 zur Ausformung A4 beaufschlagt und Öl aus der Ausformung A4 über den Flüssigkeitskanal K4 hin zum Ölabsaugbereich 5 befördert.In particular, oil is applied from the recess A6 via the liquid channel K6 to the recess A5, oil from the recess A5 is applied via the liquid channel K5 to the recess A4 and oil is conveyed from the recess A4 via the liquid channel K4 to the oil suction area 5.

Daraus ergibt sich, dass im Rahmen der Erfindung eine Flüssigkeitsförderung von Ausformung zu Ausformung hin zum Ölabsaugbereich 5 darstellbar ist.It follows from this that, within the scope of the invention, a liquid delivery from formation to formation to the oil suction area 5 can be represented.

Die Schottwandkonstruktion 1 kann folglich zusammen mit den sich drehenden Kurbelwellen- und/oder Pleuelabschnitten eine integrierte Ölförderfunktion erfüllen.The bulkhead construction 1, together with the rotating crankshaft and / or connecting rod sections, can consequently fulfill an integrated oil delivery function.

Zwischen den Ausformungen A1 bis A6 und den sich drehenden Kurbelwellen- und/oder Pleuelabschnitten wird zweckmäßig ein Spalt S zur Ölaufnahme zwischen den Ausformungen A1 bis A6 und den sich drehenden Kurbelwellen- und/oder Pleuelabschnitten ausgebildet. Es versteht sich, dass zweckmäßig pro Pleuel 3.1 bis 3.6 und/oder pro Ausformung A1 bis A6 jeweils ein Spalt S ausgebildet wird. Die Spalte S können gleich oder verschieden dimensioniert sein.Between the formations A1 to A6 and the rotating crankshaft and / or connecting rod sections, a gap S for oil absorption is expediently formed between the formations A1 to A6 and the rotating crankshaft and / or connecting rod sections. It goes without saying that a gap S is expediently formed per connecting rod 3.1 to 3.6 and / or per formation A1 to A6. The column S can have the same or different dimensions.

Die Ausformungen A1 bis A6 sind insbesondere gemäß der Hüllgeometrie der Drehbewegung der Kurbelwellen- und/oder Pleuelabschnitte ausgebildet, zusätzlich einem Abstandsmaß zur Ausbildung des Spalts S. Daraus folgt, dass die Ausformungen A1 bis A6 die Hüllgeometrie einer Kurbelwellenrotationsbewegung abbilden, zuzüglich einem definierten Abstand zur Ausbildung des Spalts S.The formations A1 to A6 are in particular designed according to the envelope geometry of the rotational movement of the crankshaft and / or connecting rod sections, in addition to a distance to form the gap S. It follows that the formations A1 to A6 map the envelope geometry of a crankshaft rotation movement, plus a defined distance to Formation of the gap S.

Mittels der Drehbewegung der Kurbelwellen- und/oder Pleuelabschnitte kann Öl aus dem jeweiligen Spalt S in den jeweiligen Flüssigkeitskanal K1 bis K6 beaufschlagt werden.By means of the rotary movement of the crankshaft and / or connecting rod sections, oil can be applied from the respective gap S into the respective liquid channel K1 to K6.

Der Ölsaugkorb im Ölabsaugbereich 5 hat ständig, insbesondere bei jeder Schräglage, unter dem Ölspiegel im Ölabsaugbereich 5 zu sein, ansonsten würde Luft angesaugt werden, so dass die Schmierung der Fahrzeugkonstruktion V (insbesondere des Motors) nicht mehr gewährleistet wäre.The oil suction basket in the oil suction area 5 always has to be below the oil level in the oil suction area 5, especially in every inclined position, otherwise air would be sucked in, so that the lubrication of the vehicle structure V (especially the engine) would no longer be guaranteed.

Die Ölförderung aus den Ausformungen A1 bis A6 und somit die Effektivität der in die Schottwandkonstruktion 1 integrierten Ölförderfunktion hängt insbesondere ab vom Spaltmaß des Spalts S (je kleiner der Spalt S, desto kleiner die Spaltverluste) und von den Durchlassquerschnitten der Ölkanäle K1 bis K6.The oil delivery from the formations A1 to A6 and thus the effectiveness of the oil delivery function integrated in the bulkhead construction 1 depends in particular on the gap size of the gap S (the smaller the gap S, the smaller the gap losses) and of the passage cross-sections of the oil channels K1 to K6.

Die Ölförderung aus den Ausformungen A1 bis A6 und somit die Effektivität der in die Schottwandkonstruktion 1 integrierten Ölförderfunktion ist ferner abhängig vom Betriebszustand der Fahrzeugvorrichtung V, insbesondere von der Motor- und/oder der Kurbelwellendrehzahl der Fahrzeugvorrichtung V.The oil delivery from the formations A1 to A6 and thus the effectiveness of the oil delivery function integrated in the bulkhead structure 1 is also dependent on the operating state of the vehicle device V, in particular on the engine and / or the crankshaft speed of the vehicle device V.

Befindet sich die Fahrzeugvorrichtung V in einer erhöhten Schräglage, sorgt die Ölförderfunktion dafür, dass eine ständige Ölförderung aus den Ausformungen A1 bis A6 zum Ölabsaugbereich 5 stattfindet, so dass die Gefahr einer Luftansaugung reduziert oder gar gänzlich vermieden werden kann.If the vehicle device V is in an elevated inclined position, the oil delivery function ensures that there is constant oil delivery from the formations A1 to A6 to the oil suction area 5, so that the risk of air being drawn in can be reduced or even avoided entirely.

Figur 2 zeigt eine andere Schnittansicht der Schottwandkonstruktion 1 und der Ölauffangvorrichtung F der Figur 1, wobei zu Darstellungszwecken nicht alle Teile mit Bezugszeichen versehen sind. Figure 2 FIG. 8 shows another sectional view of the bulkhead structure 1 and the oil collecting device F of FIG Figure 1 , not all parts being provided with reference numerals for purposes of illustration.

Figuren 3 und 4 zeigen eine Schottwandkonstruktion 1 gemäß einer Ausführungsform der Erfindung, die wie in den Figuren 1 und 2 ausgeführt ist. Figures 3 and 4 show a bulkhead construction 1 according to an embodiment of the invention, which as in FIGS Figures 1 and 2 is executed.

Figur 3 zeigt insbesondere die Ausformungen A4 bis A6 und die zugehörigen Kanäle K4 bis K6, während Figur 4 insbesondere die Ausformungen A1 bis A3 und die zugehörigen Kanäle K1 bis K3 zeigt. Figure 3 shows in particular the formations A4 to A6 and the associated channels K4 to K6, while Figure 4 shows in particular the formations A1 to A3 and the associated channels K1 to K3.

Bezugszeichen 7 kennzeichnet optionale Aussparungen in der Schottwandkonstruktion 1 für die Kurbelwellenlagerung.Reference 7 denotes optional recesses in the bulkhead construction 1 for the crankshaft bearing.

Die Ölkanäle K3 und K4 sind sehr kurz ausgeführt und können im Rahmen der Erfindung als bloße Öldurchlassöffnung ausgeführt sein.The oil channels K3 and K4 are very short and can be designed as a mere oil passage opening within the scope of the invention.

Die Figur 4 zeigt, dass ein Eintritt eines Ölkanals in einer Ausformung ausgebildet sein kann, der zugehörige Austritt aber nicht zwangsläufig in einer Ausformung ausgebildet sein muss, sondern auch benachbart dazu ausgebildet sein kann. In letztgenanntem Fall hat die Schottwandkonstruktion 1 zweckmäßig so ausgeführt zu sein, dass Öl aus dem Austritt in die zugehörige Ausformung fließen kann. Hierzu kann die Schottwandkonstruktion 1 z. B. einen Neigungsabschnitt hin zur zugehörigen. Ausformung aufweisen.The Figure 4 shows that an inlet of an oil channel can be formed in a formation, but the associated outlet does not necessarily have to be formed in a formation, but can also be formed adjacent to it. In the latter case, the bulkhead construction 1 has to be expediently designed so that oil can flow from the outlet into the associated formation. For this purpose, the bulkhead structure 1 z. B. a slope section towards the associated. Have molding.

Figur 5 zeigt eine Schnittansicht der Schottwandkonstruktion 1 und der Ölauffangvorrichtung F nebst der Fahrzeugkonstruktion V der Figuren 1 und 2. Figure 5 shows a sectional view of the bulkhead construction 1 and the oil collecting device F together with the vehicle construction V of FIG Figures 1 and 2 .

Aus Figur 5 wird nochmals das Funktionsprinzip der Erfindung ersichtlich, nämlich, dass in der Schottwandkonstruktion eine Ausformung zur Aufnahme eines sich drehenden, unteren Kurbelwellen- und/oder Pleuelabschnitts ausgebildet ist und durch den sich drehenden Kurbelwellen- und/oder Pleuelabschnitt Öl aus der Ausformung, insbesondere aus dem Spalt zwischen der Ausformung und dem sich drehenden Kurbelwellen- und/oder Pleuelabschnitt, hinausbeförderbar ist, insbesondere in einen Ölkanal, so dass zweckmäßig eine Ölforderung hin zum Ölabsaugbereich ermöglicht wird.Out Figure 5 the functional principle of the invention can be seen again, namely that in the bulkhead construction a recess for receiving a rotating, lower crankshaft and / or connecting rod section is formed and through the rotating crankshaft and / or connecting rod section oil from the recess, in particular from the Gap between the formation and the rotating crankshaft and / or connecting rod section, can be conveyed out, in particular into an oil channel, so that it is expedient for an oil demand to be made possible to the oil suction area.

Es versteht sich, dass im Rahmen der Erfindung pro Pleuel eine Ausformung vorgesehen ist.It goes without saying that, within the scope of the invention, one formation is provided per connecting rod.

Figur 6 zeigt eine schematische perspektivische Ansicht zweier benachbarter Ausformungen A6 und A5, insbesondere zweier Pleuel-Geigen mit Aufmaß. Figure 6 shows a schematic perspective view of two adjacent formations A6 and A5, in particular two connecting rod violins with allowance.

Figur 6 ist zunächst zu entnehmen, dass die Ölkanäle K6 und K5 zur Verbindung der zwei Ausformungen A6 und A5 dienen. Der Eintritt des Ölkanals K6 ist in der Ausformung A6 ausgebildet, dessen Austritt benachbart zur Ausformung A5. Der Eintritt des Ölkanals K5 ist in der Ausformung A5 ausgebildet, dessen Austritt kann in der Ausformung A4 oder benachbart dazu ausgebildet sein. Figure 6 it can be seen first that the oil channels K6 and K5 serve to connect the two formations A6 and A5. The inlet of the oil channel K6 is formed in the formation A6, the outlet of which is adjacent to the formation A5. The inlet of the oil channel K5 is formed in the formation A5, the outlet of which can be formed in the formation A4 or adjacent thereto.

Figur 6 zeigt darüber hinaus, dass der Durchlassquerschnitt der jeweiligen Ölkanäle K6 und K5 verjüngend ausgeführt ist und zwar in Öl-Förderrichtung, also von der Ausformung A6 zur Ausformung A5. Dadurch ist ein Druckunterschied und/oder eine Öl-Förderwirkung erzielbar. Figure 6 also shows that the passage cross-section of the respective oil channels K6 and K5 is designed to taper, namely in the oil delivery direction, that is, from the formation A6 to the formation A5. As a result, a pressure difference and / or an oil delivery effect can be achieved.

Der sich verengende Durchlassquerschnitt führt zweckmäßig zu einer Beschleunigung des beförderten Öls. Der Ölmassenstrom am Austritt eines Ölkanals kann gegen die benachbarte Ausformung geworfen werden oder benachbart dazu ausströmen.The narrowing passage cross-section expediently leads to an acceleration of the transported oil. The oil mass flow at the outlet of an oil channel can be thrown against the adjacent formation or flow out adjacent to it.

Figur 7 zeigt eine perspektivische Ansicht der Schottwandkonstruktion 1, der Ölauffangvorrichtung F und der Fahrzeugkonstruktion V mit der Kurbelwelle 2 und den Pleuel 3.1 bis 3.6. Figure 7 shows a perspective view of the bulkhead construction 1, the oil collecting device F and the vehicle construction V with the crankshaft 2 and the connecting rods 3.1 to 3.6.

Zu sehen ist nochmals, dass je Pleuel 3.1 bis 3.6 und somit je Pleuel- und/oder Kurbelwellenabschnitt je eine Ausformung A1 bis A6 in der Schottwandkonstruktion 1 ausgebildet ist. Ebenfalls ist je Ausformung A1 bis A6 je ein Ölkanal K1 bis K6 ausgebildet.It can be seen again that for each connecting rod 3.1 to 3.6, and thus for each connecting rod and / or crankshaft section, one formation A1 to A6 is formed in the bulkhead construction 1. An oil channel K1 to K6 is also formed for each recess A1 to A6.

Figur 8 zeigt eine vereinfachte Schnittansicht zur nochmaligen Illustration des Funktionsprinzips der Erfindung. Zu sehen und benannt sind insbesondere die Kurbelwelle, ein Pleuel, ein Kurbelwellen- und/oder Pleuelabschnitt, insbesondere unterer, zweckmäßig unterster Kurbelwelle- und/oder Pleuelabschnitt, und eine Ausformung. Figure 8 shows a simplified sectional view to once again illustrate the functional principle of the invention. In particular, the crankshaft, a connecting rod, a crankshaft and / or connecting rod section, in particular the lower, expediently lowermost crankshaft and / or connecting rod section, and a formation can be seen and named.
