Description

Die Erfindung bezieht sich auf ein Verzögerungsteil nach dem Oberbegriff des Anspruches 1.The invention relates to a delay part according to the preamble of claim 1.

Aus der Zeitschrift ATZ 89 (1987) 2 Seite 69 ist ein als sogenannter Ölhobel wirkendes Ölschwallblech bekannt, welches mit einer flanschförmig ausgebildeten Berandung versehen in einer horizontalen, in einer Ebene liegenden Fläche zwischen einem Zylinderblock und einer Ölwanne angeordnet ist. Das Ölschwallblech ist mit Öldurchtritten versehen, welche rückfließendes Schmieröl aus einem oberhalb des Bleches liegenden Raum in einen unterhalb befindlichen Raum leitet.From the magazine ATZ 89 (1987) 2 page 69 an oil baffle acting as a so-called oil plane is known, which is provided with a flange-shaped edge in a horizontal plane lying between a cylinder block and an oil pan. The oil baffle is provided with oil passages, which directs the back-flowing lubricating oil from a room above the sheet into a room below.

Aufgabe der vorliegenden Erfindung ist es, das verschäumte Öl in einer Brennkraftmschine weitestgehend zu entschäumen.The object of the present invention is to largely defoam the foamed oil in an internal combustion engine.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Weitere, die Erfindung vorteilhaft ausgestaltende Merkmale sind in den Unteransprüchen benannt.
Durch die Anordnung des Verzögerungsteils wird ein kurzschlußartiges Ansaugen von verschäumtem Öl verhindert. Bei einem benachbart einer mit Dichtungen versehenen Fläche zwischen Kurbelgehäuse und Ölwanne angeordneten Verzögerungsteil muß das aus dem Kurbelraum abtropfende, verschäumte Öl zunächst auf dem Verzögerungsteil bis zu dessen Berandung und durch die dort angeordneten Öldurchtritte und unter dem Verzögerungsteil zurück zum zentral angeordneten Saugkorb strömen. Die dadurch erzwungene zeitliche Verzögerung bis zum Ansaugen bewirkt eine gute Entschäumung des Öles.This object is achieved by the characterizing features of claim 1. Further features which advantageously design the invention are specified in the subclaims.
The arrangement of the delay part prevents a short-circuit-like suction of foamed oil. In the case of a delay part arranged adjacent to a surface provided with seals between the crankcase and the oil pan, the foamed oil dripping from the crankcase must first flow on the delay part up to its boundary and through the oil passages arranged there and under the delay part back to the centrally arranged suction basket. The consequent time delay until the suction causes a good defoaming of the oil.

Der gleiche Vorteil wird bei einer Anordnung des Verzögerungsteil benachbart einer mit Dichtungen versehenen Fläche einer horizontalen geteilten Ölwanne zwischen dem als Vorratsbehälter dienenden tiefen Teil der Ölwanne und dem ihn unten verschließenden Deckel erzielt. Das etwa mittig in den Vorratsbehälter aus dem Kurbelgehäuse rückfließende Öl muß die o.g. Verzögerungsstrecke bis zu dem zwischen Verzögerungsteil und Deckel im Ölsumpf liegenden Saugkorb zurücklegen.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung wird das Verzögerungsteil an einer Ölpumpe gehalten und erstreckt sich bis nahe an den inneren Rand der mit Dichtungen versehenen Fläche. Zur Befestigung weist das Verzögerungsteil eine Öffnung auf, in die der Saugkorb gesteckt wird und deren Randbereich mit einem Flansch der Ölpumpe lösbar verbunden ist.The same advantage is achieved with an arrangement of the delay part adjacent to a surface of a horizontal split oil pan provided with seals between the deep part of the oil pan serving as a reservoir and the cover closing it below. The oil flowing back approximately in the middle of the reservoir from the crankcase must be the above Cover the deceleration distance to the suction basket between the deceleration part and the cover in the oil sump.
According to an advantageous embodiment of the invention, the deceleration part is held on an oil pump and extends to close to the inner edge of the surface provided with seals. For fastening, the delay part has an opening into which the suction basket is inserted and the edge region of which is detachably connected to a flange of the oil pump.

In weiterer Ausgestaltung ist die Berandung flanschförmig ausgebildet und in der Fläche verspannt. Vorteilhafterweise kann dabei eine beidseitig wirkende Dichtung in die Berandung integriert werden, so daß die üblichen, separaten Dichtungen entfallen. Im Bereich der Verschraubung zwischen den an die Fläche grenzenden Teilen sind Distanzhülsen in die Dichtung integriert, so daß eine über den gesamten Umfang gleichmäßige, ein Zerquetschen der Dichtung verhindernde Pressung vorliegt.In a further embodiment, the edge is flange-shaped and braced in the surface. Advantageously, a double-acting seal can be integrated into the border, so that the usual, separate seals are not required. In the area of the screw connection between the parts adjoining the surface, spacer sleeves are integrated in the seal, so that there is a uniform pressure over the entire circumference that prevents the seal from being crushed.

Das Verzögerungsteil ist einfach als Stanzteil aus Blech oder als Spritzteil aus Kunststoff herstellbar. Die Dichtung wird anschließend gemeinsam mit den Distanzhülsen als Elastomer anvulkanisiert. Bei einer Kunststoffausführung lassen sich in einfacher Weise auf der dem Ölsumpf zugewandten Unterseite des Verzögerungsteiles von der Berandung aus in Richtung auf die Öffnung für den Saugkorb verlaufende Rippen anordnen. Diese leiten das im Sumpf befindliche Öl bei Beschleunigungen zwangsweise am Saugkorb entlang.The delay part is easy to produce as a stamped part made of sheet metal or as a molded part made of plastic. The seal is then vulcanized together with the spacers as an elastomer. In the case of a plastic design, ribs extending in the direction of the opening for the suction basket can be arranged in a simple manner on the underside of the delay part facing the oil sump. These automatically direct the oil in the sump along the suction strainer during acceleration.

Vorteilhaft ist weiterhin, daß sich das unterhalb des Verzögerungsteils befindende Öl bei starken Beschleunigungen erheblich weniger verlagert, als der oberhalb stehende Teil der Schmierölmenge, da das Öl aus dem Ölsumpf nur vergleichsweise langsam über die Öldurchtritte nach oben gelangen kann. Damit ist ein ständiges Umspülen des Saugkorbes gewährleistet.It is also advantageous that the oil located below the deceleration part is displaced considerably less than the part of the lubricating oil quantity above, since the oil from the oil sump can reach the oil passages only comparatively slowly. This ensures that the suction basket is constantly washed around.

Ein Ausführungsbeispiel wird anhand von Figuren näher erläutert.

  • Fig.1 eine Draufsicht eines Verzögerungsteiles, teilweise als Rohteil,
  • Fig.2 einen Schnitt eines Rohteiles entlang der Linie II-II gemäß Fig.1,
  • Fig.3 einen Schnitt entlang der Linie III-III gemäß Fig.1 und
  • Fig.4 einen Schnitt entlang der Linie IV-IV gemäß Fig.1
An embodiment is explained in more detail with reference to figures.
It shows:
  • 1 is a plan view of a delay part, partly as a blank,
  • 2 shows a section of a blank along the line II-II according to FIG. 1,
  • 3 shows a section along the line III-III of Figure 1 and
  • 4 shows a section along the line IV-IV according to FIG

Ein Verzögerungsteil 1 erstreckt sich in dem nicht näher gezeigten Gehäuse einer Brennkraftmaschine für ein Kraftfahrzeug in einer Ebene E1. Diese Ebene E1 schließt eine Fläche F zwischen dem als Vorratsbehälter V für Schmieröl wirkenden tiefen Teil einer Ölwanne und einem diesen Behälter nach unten verschließenden Deckel 2 ein. In dem Vorratsbehälter V ist oberhalb des Verzögerungsteiles 1 eine nur angedeutete Ölpumpe 3 angeordnet. In einem Zentrum des etwa rechteckigen Verzögerungsteiles 1 ist eine Öffnung 4 vorgesehen, deren Randbereich 5 über Verschraubungen 6 mit einem Flansch der Ölpumpe 3 verbunden ist.
Das Verzögerungsteil 1 besteht aus einem gestanzten Rohteil 7, auf dessen äußere, flanschförmige Berandung 8 eine beidseitig wirkende Dichtung 9 aufgebracht ist. Die Dichtung 9 umschließt die Berandung 8 U-förmig und weist Dichtlippen 10 auf. An der Berandung 8 des Rohteiles 7 sind nach innen gerichtete Einbuchtungen 11 angeordnet, benachbart derer kleine Öffnungen 12 das Verzögerungsteil 1 durchsetzen. Die Einbuchtungen 11 dienen der Aufnahme von in die Dichtung 9 eingebetteten Distanzhülsen 13. Durch diese hindurch erfolgt die Verschraubung des Deckels 2 an den Vorratsbehälter V und gleichzeitig das Verspannen des Verzögerungsteiles 1 in der Fläche F. Entlang der in Fahrtrichtung X-X des Kraftfahrzeuges liegenden Teile der Berandung 8 sind mehrere Öldruchtritte 14 angeordnet.A deceleration part 1 extends in the housing (not shown in more detail) of an internal combustion engine for a motor vehicle in a plane E1. This level E1 encloses a surface F between the deep part of an oil pan acting as a storage container V for lubricating oil and a cover 2 closing this container downwards. An oil pump 3, which is only indicated, is arranged in the reservoir V above the delay part 1. An opening 4 is provided in a center of the approximately rectangular deceleration part 1, the edge region 5 of which is connected to a flange of the oil pump 3 via screw connections 6.
The delay part 1 consists of a stamped blank 7, on the outer, flange-shaped edge 8 a bilateral seal 9 is applied. The seal 9 surrounds the edge 8 in a U-shape and has sealing lips 10. On the edge 8 of the blank 7 inward indentations 11 are arranged, adjacent small openings 12 penetrate the delay part 1. The indentations 11 serve to receive spacer sleeves 13 embedded in the seal 9. The cover 2 is screwed through this to the storage container V and, at the same time, the deceleration part 1 is braced in the area F. Along the parts of the motor vehicle lying in the direction of travel XX of the vehicle Border 8 a plurality of oil passages 14 are arranged.

Im Betrieb der Brennkraftmaschine tritt das aus dem Kurbelgehäuse zurückströmende , verschäumte Schmieröl über einen nahezu mittig oberhalb der Öffnung 4 liegenden Einlaß in den Vorratsbehälter V. Um zu dem unterhalb des Verzögerungsteiles 1 liegenden, von oben durch die Öffnung 4 gesteckten Saugkorb 15 im Ölsumpf S zu gelangen, wird das Schmieröl zwangsläufig vom Einlaß zu den Öldurchtritten 14 und von dort zurück zum Saugkorb 15 fließen. Entlang dieser Verzögerungsstrecke entgast das Öl nahezu vollständig.During operation of the internal combustion engine, the foamed lubricating oil flowing back from the crankcase enters the reservoir V through an inlet located almost centrally above the opening 4, in order to the suction basket 15 in the oil sump S located below the delay part 1 and inserted through the opening 4 from above get, the lubricating oil will inevitably flow from the inlet to the oil passages 14 and from there back to the suction strainer 15. The oil degasses almost completely along this delay line.

Der Ölsumpf S weist eine geringe Bauhöhe auf, so daß nur eine kleine Ölmenge zwischen Deckel 2 und Verzögerungsteil 1 verbleibt. Die restliche Ölmenge befindet sich bei normalem Fahrbetrieb oberhalb der Ebene E1 und somit auch der Ölspiegel. Frisch in den Vorratsbehälter V strömendes, verschäumtes Öl muß vom Ölspiegel bis in die Nähe des Verzögerungsteiles 1 sinken, wodurch zusätzliche Zeit zum Entgasen vorhanden ist.The oil sump S has a low overall height, so that only a small amount of oil remains between cover 2 and delay part 1. The remaining amount of oil is above level E1 during normal driving and thus also the oil level. Foamed oil freshly flowing into the reservoir V must sink from the oil level to the vicinity of the delay part 1, which means that there is additional time for degassing.

Bei einer Ausführung des Rohteiles 7 als Kunststoff-Spritzteil können an der dem Ölsumpf S zugewandten Unterseite des Verzögerungsteiles 1 Rippen 16 angeordnet sein, wie in Fig.1 und Fig.2 gestrichelt dargestellt. Diese verlaufen von der Berandung 8 aus in Richtung auf die Öffnung 4 und leiten das Öl bei Beschleunigungen zwangsweise am Saugkorb 15 entlang.When the raw part 7 is designed as a plastic injection-molded part, ribs 16 can be arranged on the underside of the delay part 1 facing the oil sump S, as shown in broken lines in FIG. 1 and FIG. These run from the boundary 8 in the direction of the opening 4 and forcibly direct the oil along the suction basket 15 during acceleration.

Bei der Herstellung wird zunächst das Rohteil 7 als Stanzteil mit der Öffnung 4, den Einbuchtungen 11, den Öldurchtritten 14 sowie den Öffnungen 12 in einem Arbeitsgang gefertigt. Anschließend wird die Berandung 8 mit der Dichtung 9 umspritzt, wobei gleichzeitig die Distanzhülsen 13 in die Dichtung 9 integriert werden. Der Werkstoff der Dichtung 9 durchdringt beim Umspritzen die Öffnungen 12, so daß sie gegen Verrutschen gesichert ist.During manufacture, the blank 7 is first manufactured as a stamped part with the opening 4, the indentations 11, the oil passages 14 and the openings 12 in one operation. The edge 8 is then extrusion-coated with the seal 9, the spacer sleeves 13 being integrated into the seal 9 at the same time. The material of the seal 9 penetrates the openings 12 during the encapsulation, so that it is secured against slipping.

Die Höhe H der Distanzhülsen 13 begrenzt bei der Montage des Deckels 2 an den Vorratsbehälter V das Zusammenpressen der Dichtlippen 10 auf ein Maß, welches ein sicheres, beidseitiges Abdichten gewährleistet und ein Zerquetschen der Dichtung 9 verhindert.The height H of the spacer sleeves 13 limits the compression of the sealing lips 10 to a dimension when the cover 2 is mounted on the storage container V, which ensures secure sealing on both sides and prevents the seal 9 from being crushed.
