Definitions
- the invention relates to a device for guiding lubricating oil according to the preamble of patent claim 1.
- DE-42 04 522 C1 discloses a device in an internal combustion engine with a shell covering the crank mechanism toward the oil pan for draining off lubricating oil.
- the shell which partly runs along the contour of the connecting rod violin, has an oil drain opening which acts as an oil plane.
- This opens into a damping chamber for the gas impulses caused by the piston movement, this damping chamber having a further drain opening arranged below and to the side of the oil drain opening, through which the lubricating oil thrown off by the crank mechanism flows into the oil pan.
- a balance shaft can rotate, which is at least partially enclosed by two struts protruding from the shell.
- the disadvantage here is that the oil is foamed by contact with the rotating balancer shaft and gets into the oil sump in this state.
- the invention has for its object to provide a generic device arranged between the crank mechanism and the oil pan for guiding lubricating oil in an internal combustion engine in such a way that the lubricating oil emitted by the crank mechanism reaches a non-foamed oil container.
- the protruding struts of the shell form a profile that accommodates the intermediate shaft and is closed with respect to the crank mechanism, the intermediate shaft is sealed off against the entry of lubricating oil of the crank mechanism.
- This lubricating oil gets under Bypassing the rotating intermediate shaft in the oil sump and is not foamed by the rotation.
- a bottom of the shell in the area of the connecting rod violin contour is provided with these following curved segments, which run closely adjacent to this contour by means of the curvature and thus only leave a small gap in which oil can be mixed with air.
- An arrangement of two drain openings in series with respect to the direction of rotation of the crankshaft and behind the profile ensures that the lubricating oil is drained away safely.
- the amount of oil removed from the crank mechanism and thus not rotating with it can be increased if roof-shaped exposures are arranged behind the drain openings in the direction of the crankshaft, with wiping lips and extending directly to the connecting rod violin contour. These can limit drainage channels that contain the drainage openings and guide the absorbed lubricating oil into the oil sump.
- a scraper extending right up to the counterweight contour can be arranged adjacent to at least one of the exposures.
- the ends of the struts which are spaced from the bottom of the shell, can be provided, for example with elastic seals, against wall sections of the internal combustion engine in such a way that, together with the profile, they form a closed volume which extends along and receives the intermediate shaft.
- These wall sections can be side walls of a crankcase which extend downward beyond the crankshaft or walls of an oil container which is flanged to the crankcase and is designed as an oil pan.
- the one wall section can have an outlet opening for lubricating oil. The oil collected in the shaft formed between the one strut and the drainage channels and this wall section can thus be removed.
- dry sump lubrication in this outlet opening are the suction point of the oil pump, which pumps the oil into an oil tank designed as a tank.
- An outer, surrounding flange of the base can lie in a horizontal plane arranged between the crankshaft and the intermediate shaft, the flange also being supported on the wall sections with elastic seals.
- These seals can e.g. be inserted as a circular sealing ring in cross section in corresponding grooves of the flange or the struts.
- they can be provided with a sealing lip which, when in contact with the corresponding wall section, is curved.
- a suitably chosen direction of the curvature of the sealing lips ensures that, on the one hand, no oil can emerge from the shaft at locations not provided for it, on the other hand, a tunnel arranged on the opposite side of the intermediate shaft is secured against oil access from the crank mechanism and any oil in it is contained in one Channel of the volume receiving the intermediate shaft can flow off.
- a two-row internal combustion engine not shown, with a V-angle of 180 ° has a crank mechanism with an axis AA in the shown direction of the arrow rotating crankshaft 1.
- An intermediate shaft 2 rotates about its axis ZZ in the middle below the crankshaft 1.
- a crankcase is divided vertically in half in a plane EE having axes AA and ZZ.
- the halves have wall sections 3 and 4 running in a V-shape with respect to one another below the crank mechanism, with a single outlet opening 5 being arranged in section 4.
- the crank mechanism has conventional counterweights located adjacent to connecting rod journals, which result in a counterweight contour K when rotating.
- the connecting rods Z1, Z2, Z3 assigned to a row of cylinders generate a first connecting rod violin contour 6 with their connecting rods on the crank mechanism, the cylinders Z4, Z5 and Z6 assigned to the other cylinder row generate a second connecting rod violin contour 7.
- a horizontal plane HH extends between the axes AA and ZZ perpendicular to the plane EE.
- a shell 8 with a bottom 9 and an outer flange 10 extends essentially along this plane HH over the entire length of the crankshaft 1.
- Two struts 11, 12 protrude from the shell 8 symmetrically to the plane EE, which together with a piece of the bottom 9 form a profile 13 which is closed with respect to the crank mechanism and which surrounds the intermediate shaft 2 in a U-shape.
- the base 9 Below the connecting rod journals of the crankshaft 1, the base 9 has segments 14 and 15 which lie in front of the plane EE with respect to the direction of rotation of the crankshaft 1 and which follow the connecting rod violin contours 6 and 7 closely adjacent in a curved manner. Lying in a row behind the plane EE in the direction of rotation, the segments 14, 15 are adjoined by two roof-shaped displays 20 and 21, each provided with side walls 16, 17 and 18, 19. These each have wiping lips 22 and 23, which extend in the direction of the crank mechanism and point against the direction of rotation of the crankshaft 1, and which extend in the immediate vicinity of the connecting rod violet contours 6 and 7.
- a drain channel 25 having a first drain opening 24 is formed, between the exhibition 21 and the exhibition 20, a drain channel 27 having a second drain opening 26.
- a strut 12 and the Wall section 4 defines a shaft 28 which extends in parallel over the entire length of the crankshaft 1.
- a closed tunnel 29 is formed on the opposite side of the plane EE between the floor 9 or its segments 14, 15, the other strut 11 and the wall section 3.
- the elastic means are formed from attached seals 40, 41, which are each provided with a sealing lip 42, 43.
- these sealing lips 42, 43 are curved against the wall sections 3, 4 in such a way that on the one hand the shaft 28 is secured against oil leakage and on the other hand the tunnel 29 on the flange 10 is sealed against oil ingress and an outflow on the strut 12 of any oil in the tunnel 29 into a channel 44 of the volume 39 is possible. From Fig. 5 it is clear that the sealing lips 42, 43 of the struts 11, 12 in the direction of rotation of the crankshaft 1 and that of the flange 10 are pre-curved to the opposite.
- Each counterweight on the crankshaft 1 is assigned a scraper 45 which is arranged on the side walls 18 and 19 of the further exhibition 21 and extends in the immediate vicinity of the counterweight contour K.
- the lubricating oil emitted by the crank mechanism is taken up by the scraper lips 22 and 23 in the area of the connecting rods and guided into the shaft 28 via the outlet channels 25 and 27.
- the oil is gripped by the wipers 45 and fed to the shaft 28 via the discharge channel 27.
- the lubricating oil discharged from the bearings of the crankshaft 1 lying between the segments 14, 15 drips onto essentially flat surfaces 46 of the base 9 and flows to the shaft 28 via the outlet channel 25.
- the oil flows to the outlet opening 5, which is located approximately in the center with respect to the longitudinal extension of the shell 8. The distance to be covered by the oil on the floor 9, through the drain openings 24, 26 and in the shaft 28 to the outlet opening 5 enables the degassing of the lubricating oil to a large extent.

Description
Die Erfindung betrifft eine Vorrichtung zum Führen von Schmieröl gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for guiding lubricating oil according to the preamble of
Aus der DE-42 04 522 C1 ist eine Vorrichtung in einer Brennkraftmaschine mit einer den Kurbeltrieb zur Ölwanne hin abdeckenden Schale zum Ableiten von Schmieröl bekannt. Etwa mittig unterhalb der Kurbelwelle weist die teilweise entlang der Pleuelgeigenkontur verlaufende Schale eine als Ölhobel wirkende Ölablauföffnung auf. Diese mündet in eine Dämpfungskammer für die durch die Kolbenbewegung verursachten Gasimpulse, wobei diese Dämpfungskammer eine unterhalb und seitlich zur Ölablauföffnung versetzt angeordnete, weitere Ablauföffnung aufweist, über die das vom Kurbeltrieb abgeschleuderte Schmieröl in die Ölwanne strömt. In dieser Dämpfungskammer kann eine Ausgleichswelle rotieren, welche zumindest teilweise von zwei von der Schale abragenden Streben umschlossen ist. Nachteilig dabei ist, daß das Öl durch den Kontakt mit der rotierenden Ausgleichswelle verschäumt wird und in diesem Zustand in den Ölsumpf gelangt.DE-42 04 522 C1 discloses a device in an internal combustion engine with a shell covering the crank mechanism toward the oil pan for draining off lubricating oil. Approximately in the middle below the crankshaft, the shell, which partly runs along the contour of the connecting rod violin, has an oil drain opening which acts as an oil plane. This opens into a damping chamber for the gas impulses caused by the piston movement, this damping chamber having a further drain opening arranged below and to the side of the oil drain opening, through which the lubricating oil thrown off by the crank mechanism flows into the oil pan. In this damping chamber, a balance shaft can rotate, which is at least partially enclosed by two struts protruding from the shell. The disadvantage here is that the oil is foamed by contact with the rotating balancer shaft and gets into the oil sump in this state.
Der Erfindung liegt die Aufgabe zugrunde, eine zwischen Kurbeltrieb und Ölwanne angeordnete gattungsgemäße Vorrichtung zum Führen von Schmieröl in einer Brennkraftmaschine derart auszubilden, daß das vom Kurbeltrieb abgegebene Schmieröl weitgehend unverschäumt in einen Ölbehälter gelangt.The invention has for its object to provide a generic device arranged between the crank mechanism and the oil pan for guiding lubricating oil in an internal combustion engine in such a way that the lubricating oil emitted by the crank mechanism reaches a non-foamed oil container.
Die Lösung dieser Aufgabe gelingt mit den kennzeichnenden Merkmalen des Patentanspruches 1.
Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved with the characterizing features of
Advantageous embodiments of the invention are specified in the dependent claims.
Wenn bei einer gattungsgemäßen Brennkraftmaschine die abragenden Streben der Schale ein die Zwischenwelle aufnehmendes, gegenüber dem Kurbeltrieb geschlossenes Profil bilden, so ist die Zwischenwelle gegen den Zutritt von Schmieröl des Kurbeltriebes abgeschottet. Dieses Schmieröl gelangt somit unter Umgehung der rotierenden Zwischenwelle in den Ölsumpf und wird nicht durch die Rotation verschäumt.
In vorteilhafter Ausgestaltung ist ein Boden der Schale im Bereich der Pleuelgeigenkontur mit diesen folgenden, gekrümmten Segmenten versehen, welche mittels der Krümmung eng benachbart dieser Kontur verlaufen und somit lediglich einen geringen Spalt belassen, in welchem Öl mit Luft vermischt werden kann. Eine Anordnung von zwei bezüglich der Rotationsrichtung der Kurbelwelle in Reihe zueinander und hinter dem Profil liegenden Ablauföffnungen gewährleistet ein sicheres Abführen des Schmieröles.
Die Menge von vom Kurbeltrieb abgenommenem und somit nicht mit ihm rotierenden Öl läßt sich vergrößern, wenn hinter den Ablauföffnungen in Richtung der Kurbelwelle weisende, mit Abstreiflippen versehene und sich bis unmittelbar an die Pleuelgeigenkontur erstreckende dachförmige Ausstellung angeordnet sind. Diese können Ablaufkanäle begrenzen, welche die Ablauföffnungen beinhalten und das aufgenommene Schmieröl in den Ölsumpf führen.If, in a generic internal combustion engine, the protruding struts of the shell form a profile that accommodates the intermediate shaft and is closed with respect to the crank mechanism, the intermediate shaft is sealed off against the entry of lubricating oil of the crank mechanism. This lubricating oil gets under Bypassing the rotating intermediate shaft in the oil sump and is not foamed by the rotation.
In an advantageous embodiment, a bottom of the shell in the area of the connecting rod violin contour is provided with these following curved segments, which run closely adjacent to this contour by means of the curvature and thus only leave a small gap in which oil can be mixed with air. An arrangement of two drain openings in series with respect to the direction of rotation of the crankshaft and behind the profile ensures that the lubricating oil is drained away safely.
The amount of oil removed from the crank mechanism and thus not rotating with it can be increased if roof-shaped exposures are arranged behind the drain openings in the direction of the crankshaft, with wiping lips and extending directly to the connecting rod violin contour. These can limit drainage channels that contain the drainage openings and guide the absorbed lubricating oil into the oil sump.
Um zur weiteren Verbesserung auch das von den benachbart der Pleuel auf der Kurbelwelle angeordneten Gegengewichten abgeschleuderte Schmieröl aufzunehmen, kann benachbart zumindest der einen Ausstellung ein sich bis unmittelbar an die Gegengewichtkontur erstreckender Abstreifer angeordnet sein.In order to also take up the lubricating oil thrown off by the counterweights arranged on the crankshaft next to the connecting rods for further improvement, a scraper extending right up to the counterweight contour can be arranged adjacent to at least one of the exposures.
Zur vollständigen Abschottung der Zwischenwelle können die beabstandet vom Boden der Schale liegenden Enden der Streben z.B. mit elastischen Dichtungen versehen an Wandabschnitten der Brennkraftmaschine derart anliegen, daß diese zusammen mit dem Profil ein sich entlang der Zwischenwelle erstreckendes und diese aufnehmendes, geschlossenes Volumen bilden. Diese Wandabschnitte können sich über die Kurbelwelle hinaus nach unten erstreckende Seitenwände eines Kurbelgehäuses sein oder Wandungen eines an das Kurbelgehäuse geflanschten, als Ölwanne ausgebildeten Ölbehälters.
In beiden Fällen kann der eine Wandabschnitt dabei eine Austrittsöffnung für Schmieröl aufweisen. Somit kann das in dem zwischen der einen Strebe und den Ablaufkanälen sowie diesem Wandabschnitt gebildeten Schacht gesammelte Öl abgeführt werden. Im ersten Fall kann bei einer Trockensumpfschmierung in dieser Austrittsöffnung die Absaugestelle der Ölpumpe liegen, welche das Öl in einen als Tank ausgebildeten Ölbehälter fördert.To completely seal off the intermediate shaft, the ends of the struts, which are spaced from the bottom of the shell, can be provided, for example with elastic seals, against wall sections of the internal combustion engine in such a way that, together with the profile, they form a closed volume which extends along and receives the intermediate shaft. These wall sections can be side walls of a crankcase which extend downward beyond the crankshaft or walls of an oil container which is flanged to the crankcase and is designed as an oil pan.
In both cases, the one wall section can have an outlet opening for lubricating oil. The oil collected in the shaft formed between the one strut and the drainage channels and this wall section can thus be removed. In the first case, dry sump lubrication in this outlet opening are the suction point of the oil pump, which pumps the oil into an oil tank designed as a tank.
Ein außen liegender, umliegender Flansch des Bodens kann in einer zwischen der Kurbelwelle und der Zwischenwelle angeordneten horizontalen Ebene liegen, wobei sich der Flansch ebenfalls mit elastischen Dichtungen versehen an den Wandabschnitten abstützt. Diese Dichtungen können z.B. als im Querschnitt kreisrunder Dichtring in entsprechende Nuten des Flansches bzw. der Streben eingelegt sein. In einer anderen Ausführung können sie mit einer Dichtlippe versehen sein, die bei Anlage an den entsprechenden Wandabschnitt gekrümmt verläuft. Mittels der Dichtlippen lassen sich in einfacher Weise Lagetoleranzen des Bodens bzw. der Streben zu den Wandabschnitten ausgleichen. Eine geeignet gewählte Richtung der Krümmung der Dichtlippen sorgt dafür, daß einerseits aus dem Schacht kein Öl an dafür nicht vorgesehenen Stellen austreten kann, andererseits ein auf der gegenüberliegenden Seite der Zwischenwelle angeordneter Tunnel gegen Ölzutritt vom Kurbeltrieb gesichert ist und eventuell in ihm befindliches Öl in einer Rinne des die Zwischenwelle aufnehmenden Volumens abfließen kann.An outer, surrounding flange of the base can lie in a horizontal plane arranged between the crankshaft and the intermediate shaft, the flange also being supported on the wall sections with elastic seals. These seals can e.g. be inserted as a circular sealing ring in cross section in corresponding grooves of the flange or the struts. In another embodiment, they can be provided with a sealing lip which, when in contact with the corresponding wall section, is curved. By means of the sealing lips, positional tolerances of the floor or the struts to the wall sections can be compensated in a simple manner. A suitably chosen direction of the curvature of the sealing lips ensures that, on the one hand, no oil can emerge from the shaft at locations not provided for it, on the other hand, a tunnel arranged on the opposite side of the intermediate shaft is secured against oil access from the crank mechanism and any oil in it is contained in one Channel of the volume receiving the intermediate shaft can flow off.

Eine nicht näher gezeigte, zweireihige Brennkraftmaschine mit einem V-Winkel von 180° Grad weist einen Kurbeltrieb mit einer um eine Achse A-A in der gezeigten Pfeilrichtung rotierenden Kurbelwelle 1 auf. Mittig unterhalb der Kurbelwelle 1 rotiert eine Zwischenwelle 2 um ihre Achse Z-Z.
Ein Kurbelgehäuse ist vertikal in einer die Achsen A-A und Z-Z aufweisenden Ebene E-E hälftig geteilt. Die Hälften weisen unterhalb des Kurbeltriebes V-förmig zueinander verlaufende Wandabschnitte 3 und 4 auf, wobei im Abschnitt 4 eine einzige Austrittsöffnung 5 angeordnet ist.
Der Kurbeltrieb weist übliche, benachbart von Pleuelzapfen liegende Gegengewichte auf, welche bei Rotation eine Gegengewichtkontur K ergeben. Die einer Zylinderreihe zugeordneten Zylinder Z1, Z2, Z3 erzeugen mit ihren Pleueln am Kurbeltrieb eine erste Pleuelgeigenkontur 6, die der anderen Zylinderreihe zugeordneten Zylinder Z4, Z5 und Z6 eine zweite Pleuelgeigenkontur 7.A two-row internal combustion engine, not shown, with a V-angle of 180 ° has a crank mechanism with an axis AA in the shown direction of the

Zwischen den Achsen A-A und Z-Z erstreckt sich senkrecht zur Ebene E-E eine horizontale Ebene H-H. Im wesentlichen entlang dieser Ebene H-H erstreckt sich über die gesamte Länge der Kurbelwelle 1 eine Schale 8 mit einem Boden 9 und einem außen liegenden Flansch 10.
Von der Schale 8 ragen symmetrisch zur Ebene E-E zwei Streben 11, 12 ab, die gemeinsam mit einem Stück des Bodens 9 ein gegenüber dem Kurbeltrieb geschlossenes Profil 13 bilden, welches die Zwischenwelle 2 U-förmig umschließt.A horizontal plane HH extends between the axes AA and ZZ perpendicular to the plane EE.

Unterhalb der Pleuelzapfen der Kurbelwelle 1 weist der Boden 9 bezüglich der Drehrichtung der Kurbelwelle 1 vor der Ebene E-E liegende Segmente 14 bzw. 15 auf, welche gekrümmt verlaufend den Pleuelgeigenkonturen 6 bzw. 7 eng benachbart folgen.
In Drehrichtung hinter der Ebene E-E in Reihe liegend schließen sich an die Segmente 14, 15 zwei jeweils mit Seitenwänden 16, 17 bzw. 18, 19 versehene, dachförmige Ausstellung 20 bzw. 21 an. Diese weisen jeweils in Richtung auf den Kurbeltrieb ausgestellte und entgegen der Drehrichtung der Kurbelwelle 1 weisende Abstreiflippen 22 bzw. 23 auf, welche sich bis in unmittelbare Nähe der Pleuelgeigenkonturen 6 und 7 erstrecken.Below the connecting rod journals of the

Zwischen der Ausstellung 20 und der Strebe 12 ist ein eine erste Ablauföffnung 24 aufweisender Ablaufkanal 25 ausgebildet, zwischen der Ausstellung 21 und der Ausstellung 20 ein eine zweite Ablauföffnung 26 aufweisender Ablaufkanal 27. Unterhalb dieser Ablauföffnungen 24 und 26 wird durch die eine Strebe 12 und den Wandabschnitt 4 begrenzt ein Schacht 28 gebildet, welcher sich parallel über die gesamte Länge der Kurbelwelle 1 erstreckt.

Beabstandet vom Boden 9 liegende Enden 30, 31 der Streben 11, 12 liegen unter Zwischenschaltung elastischer Mittel an den Wandabschnitten 3, 4 an. Weitere elastische Mittel sind zwischen dem Flansch 10 und diesen Wandabschnitten 3, 4 angeordnet.
Gemäß Fig. 3 sind diese Mittel als in Nuten 32 eingelegte Dichtringe 33, 34 ausgebildet, welche gemäß Fig. 7 umlaufend ausgebildet sind. Die Schale 8 ist dabei endseitig von Wänden 35, 36 begrenzt, welche sich vom Boden 9 aus bis nahe an die Wandabschnitte 3 und 4 erstrecken und an diesen unter Vermittlung der elastischen Mittel anliegen. Im Bereich der jeweils endseitigen Lager der Kurbelwelle 1 weist die Schale 8 sich über diese Wände 35, 36 hinaus erstreckende Dächer 37, 38 auf.
Aus den Figuren 3 und 4 ist ersichtlich, daß die Zwischenwelle 2 in einem in radialer Richtung geschlossenen Volumen 39 rotiert.
In einer Variante gemäß Fig. 5 sind die elastischen Mittel aus aufgesteckten Dichtungen 40, 41 gebildet, welche jeweils mit einer Dichtlippe 42, 43 versehen sind. Im in die Brennkraftmaschine eingebauten Zustand liegen diese Dichtlippen 42, 43 derart gekrümmt an den Wandabschnitten 3, 4 an, daß einerseits der Schacht 28 gegen Ölaustritt gesichert ist und andererseits der Tunnel 29 am Flansch 10 gegen Ölzutritt abgedichtet ist und an der Strebe 12 ein Abfließen von eventuell im Tunnel 29 befindlichem Öl in eine Rinne 44 des Volumens 39 möglich ist.

Im Betrieb der Brennkraftmaschine wird das vom Kurbeltrieb abgegebene Schmieröl im Bereich der Pleuel von den Abstreiflippen 22 und 23 aufgenommen und über die Ablaufkanäle 25 und 27 in den Schacht 28 geführt. Im Bereich der Gegengewichte wird das Öl von den Abstreifern 45 erfaßt und über den Ablaufkanal 27 dem Schacht 28 zugeführt. Das von den zwischen den Segmenten 14, 15 liegenden Lagern der Kurbelwelle 1 abgegebene Schmieröl tropft auf im wesentlich flach ausgebildete Flächen 46 des Bodens 9 und fließt über Ablaufkanal 25 dem Schacht 28 zu.
