Die Erfindung bezieht sich auf ein Kurbelgehäuse-Unterteil für eine !Brennkraftnuischine; insbecondere nit Irockensumpf« Schmierung»The invention relates to a crankcase lower part for a! Brennkraftnuischine ; in particular with dry sump «lubrication»

Die der Erfindung zugrunde liegende Aufgabe besteht darin, die schädliche Planscharbeit im Schmiermittel-Sumpf zu vermindern«.The object on which the invention is based is to reduce the harmful splashing work in the lubricant swamp «.

Zur Lösung der genannten Aufgabe wird g&ir.äß -ier Ei"findung vorgeschlagen, daß zwischen dem Sumpf lind den drehenden Maschinenteilen ein flüssi^keitsdurchlässiger Zwischen= boden angeordnet ist. Durch die Erfindung werden mehrere Vorteile erzielt. Der Ölstrom. im Sumpf zur Absaugstelle ist beruhigt und wird durch die umlaufenden Massen nicht gestört. Der Aba band zwischen dem Sumpf und den drehenden Maschinenteilen kann daher trotz Anordnung des Zwischen= bodens kleiner gehalten v/erden, wodurch das Kurbelgehäuseflächer baut. .In order to solve the stated problem, there is no problem finding suggested that between the swamp lind the rotating Machine parts a liquid-permeable intermediate = floor is arranged. Several advantages are achieved by the invention. The oil flow. in the sump to the suction point is calm and is not disturbed by the surrounding crowds. The aba tied between the swamp and the rotating ones Machine parts can therefore be kept smaller despite the arrangement of the intermediate floor, whereby the crankcase flats builds. .

" Mach einem weiteren Merkmal der Erfindung können in dem Bereicli des Zwischenbodens oberhalb.einer Mündung des leitungs= Systemes für die Absaugung des Schmiermittels flüssigkeits= dichte Abdeckteile angeordnet sein. Hierdurch ist verhindert, daß der beruhigte Einlauf des Schmiermittels in die Absaug= nändung von dem durch den Zwischenboden spritzenden öl- bzw. Luftwirbel· der Pleuel- bzw. G-egengewicht3 gestört wird und keine zusätzlichen Ansaugverluste für die Ölabsaugpumpen entstehen."Another feature of the invention can be in the area of the intermediate floor above an opening of the line = System for the suction of the lubricant liquid = be arranged tight cover parts. This prevents the calm inflow of the lubricant into the suction = nändung of the oil or oil spraying through the intermediate floor Air vortex · the connecting rod or counterweight3 is disturbed and no additional suction losses for the oil suction pumps develop.

Nach einem anderen. Merkmal der Erfindung können auf der den drehenden Maschinenteilen zugekehrten Seite des Zwischenbodens Ablenkteile für schleuderndes Schmiermittel vorgesehen sein. Hierdurch wird das Entstehen einer von den. drehenden Teilen.According to another. Feature of the invention can be based on the Rotating machine parts facing side of the intermediate floor may be provided deflection parts for slinging lubricant. This creates the emergence of one of the. rotating parts.

Wie ein Kurbelgehäuse mit-den-Merkmalen der Erfindung beispielsweise ausgeführt sein kann, ist im folgenden anhand der Zeichnung beschrieben. In der-Zeichnung bedeutenLike a crankcase with the features of the invention can be executed, for example, is described below with reference to the drawing. In the drawing mean

Fig. 1 einen Querschnitt durch ein Kurbelgehäuse-Unterteil undFig. 1 shows a cross section through a crankcase lower part and

Pig. 2 einen Längsschnitt durch ein :." Kurbelgehäuse-Unterteil in schematischer Darstellung.Pig. 2 shows a longitudinal section through a : "crankcase lower part in a schematic representation.

In Fig. 1 ist ein Kurbelgehäuse-Unterteil 10 gezeigt, bei dem dicht oberhalb des Gehäusebodens 11 ein-.Zwischen= boden 12 aus Blech mittels Schrauben 13 an Gehäusestützen U-bis 16 befestigt ist.In Fig. 1, a crankcase lower part 10 is shown, in which just above the housing bottom 11 a-.between = bottom 12 made of sheet metal by means of screws 13 on housing supports U-bis 16 is attached.

Die zur Kurbelwellenachse 17 radial äußersten Bahnen der : rotierenden Maschinenteile sind mit 18, 19, 2Ό und 21 bezeichnet.The radially outermost tracks of the crankshaft axis 17: rotating machine parts are marked with 18, 19, 2Ό and 21 designated.

Aus dem Blechboden 12 sind Ablenkzungen 12a ausgestanzt bzw. geformt, welche die in Pfeilrichtung 22 mitgewirbelten Öl-Luft-Gemischteilchen auffangen und durch die Löcher 12b des Zwischenbodens in den Sumpf leiten. Die Löcher 12b sind durch Ausstanzen der Zungen 12a entstanden.Deflection tongues 12a are punched out of the sheet metal base 12 or shaped, which in the direction of arrow 22 swirled oil-air mixture particles Catch and guide through the holes 12b of the false floor into the sump. The holes 12b are through The tongues 12a were punched out.

In I"ig. 2 ist mit 23 das Kurbelgehäuse-Unterteil und mit 24 der gelochte Zwischenboden bezeichnet. An einer Stirnseite des Unterteiles 25 ist ein quer zur Kurbelwellenachse verlaufen= der Absaugkanal 25 vorgesehen, der ober ein Sieb 26 und einen Absaugstutzen 27 in. den Sumpf des Kurbelgehäuses mündet. Über der sumpfseitigen öffnung 28 des Absaugstutzens'27 ist ein flüssigkeitsdichtes Abdeckblech 29 ortsfest angeordnet, das eine Beruhigung der Eintrittsströmung an der öffnung 28 auch dann bewirkt, wenn oberhalb der letzteren rotierende Maschinenteile Öl- bzw. ölgemischteilchen in den Sumpf-schleudern.In Fig. 2, 23 denotes the lower part of the crankcase and 24 denotes the perforated intermediate floor. At one end of the lower part 25 there is a suction channel 25 running transversely to the crankshaft axis, which above a sieve 26 and a suction nozzle 27 in. opens the bottom of the crankcase. above the bottoms side opening 28 of the Absaugstutzens'27 is a liquid-tight cover plate 29 is arranged stationarily, which also causes a stabilization of the inlet flow at the opening 28 when above the latter rotating parts of oil or ölgemischteilchen in the sump -sling.
