Abstract

The drive from the engine is taken through the bolts to the inner housing and through the clutch discs to the output shaft. Oil supplied to the clutch drains into the outer housing. The oil is then pumped back to the engine sump by means of a number of radial blades fixed to the clutch ring. The oil flows out through a pipe which is arranged tangentially to the tip circle of the blades. This method of returning the oil to the sump eliminates the need for a special pump and also prevents oil flowing into the flywheel housing.

Description

Brennkraftmaschine mit ange-Internal combustion engine with

bauter Kupplung Die Erfindung betrifft eine Brennkraftmaschine mit einer an einem Schwungrad befestigten ölgekühlten und ölgeschmierten Kupplung, deren Gehäuse über einen Ölkanal mit dem Gehäuse der Brennkraftmaschine verbunden ist.builder clutch The invention relates to an internal combustion engine an oil-cooled and oil-lubricated clutch attached to a flywheel, whose Housing is connected to the housing of the internal combustion engine via an oil duct.

Eine derartige Brennkraftmaschine ist bekannt (DT-OS 2 257 659).Such an internal combustion engine is known (DT-OS 2 257 659).

Dabei ist das Kupplungsgehäuse und die Ölwanne der Brennkraftmaschine so aneinander angepaßt, daß ein gemeinsamer Öl sumpf entsteht. Zwischen den beiden Gehäusen sind große Übertrittsöffnungen durch die das Schmier- und Kühlöl in den gemeinsamen Sumpf zurückfließen kann. Soll die Brennkraftmaschine ohne nasse Kupplung verwendet werden, muß die Ölwanne weitgehend geändert werden.The clutch housing and the oil pan are the internal combustion engine so adapted to each other that a common oil sump is created. Between the two Housings are large transfer openings through which the lubricating and cooling oil enters the common swamp can flow back. Should the internal combustion engine be without a wet clutch are used, the oil pan must be largely changed.

Verwendet man ein von der Motorölwanne getrenntes Kupplungsgehäuse, um das Anlasserzahnrad in einem ölfreien Zwischengehäuse anzuordnen, so ist eine besondere Ölpumpe notwendig, die das öl aus dem Kupplungsgehäuse in den gemeinsamen ölsumpf zurückpumpt.If you use a clutch housing that is separate from the engine oil pan, to arrange the starter gear in an oil-free intermediate housing, so is one special oil pump is necessary, which brings the oil from the clutch housing into the joint oil sump pumped back.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Brennkraftmaschine der eingangs beschriebenen Art eine besondere Ölpumpe einzusparen, ohne auf der Seite der Brennkraftmaschine tiefgreifende Änderungen vornehmen zu müssen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Schwungrad oder einem rotierenden Kupplungsteil Schaufeln befestigt sind, in deren Bereich der Ölkanal tangential entgegen der Drehrichtung in das Kupplungsgehäuse einmündet.The invention is based on the object in an internal combustion engine of the type described above to save a special oil pump without having to rely on the Side of the internal combustion engine to have to make profound changes. These The object is achieved in that on the flywheel or a rotating Coupling part blades are attached, in the area of which the oil channel is tangential opens into the clutch housing against the direction of rotation.

Durch die erfindungsgemäße Anordnung der Schaufeln wird im Zusammenwirken mit dem tangential einmündend@@ Ölkanal eine ausreichende Ölmenge in den gemeinsamen Ölsumpf zurückgefördert.The inventive arrangement of the blades is in cooperation with the tangential opening @@ oil channel a sufficient amount of oil in the common Oil sump pumped back.

Dabei kann sich an den Ölkanal eine normal bemessene Rohrleitung anschließen, die an den Gehäusen nur übliche Rohranschlüsse erfordert.A normal sized pipe can be connected to the oil channel, which only requires the usual pipe connections on the housings.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Fig. 1 zeigt einen teilweisen Längsschnitt durch eine erfindungsgemäße Kupplung, Fig. 2 zeigt eine Ansicht in Richtung des Pfeiles II in Abbildung 1.Fig. 1 shows a partial longitudinal section through an inventive Coupling, FIG. 2 shows a view in the direction of arrow II in FIG. 1.

Die Zeichnung stellt im wesentlichen eine Kupplung üblicher Bauart dar mit einem Gehäuse 1, einer mit einer Antriebswelle durch Schrauben 2 befestigten Kupplungsglocke 3, Kupplungslamellen 4 und einem auf einer Abtriebswelle 5 drehfest gelagerten Sekundärteil 6. Betätigt wird die Kupplung über Betätigungselemente 7 und einer Kupplungsscheibe 8.The drawing essentially represents a coupling of conventional design Dar with a housing 1, one with a drive shaft fastened by screws 2 Clutch bell 3, clutch plates 4 and one on an output shaft 5 in a rotationally fixed manner secondary part 6. The clutch is actuated via actuating elements 7 and a clutch disc 8.

An der als Schwungrad ausgebildeten Kupplungsglocke 3 sind Schaufeln 9 befestigt, in deren Bereich ein ölkanal 10 tangential entgegen der Drehrichtung 11 in das Kupplungsgehäuse 1 einmündet. Bei Rotation der Kupplungsglocke 3 wird das Kühl-und Schmieröl von den Schaufeln 9 erfaßt und durch den ölkanal 10 in das nicht näher dargestellte Gehäuse der Brennkraftmaschine gefördert.On the clutch bell 3, which is designed as a flywheel, there are blades 9 attached, in the area of an oil channel 10 tangentially opposite to the direction of rotation 11 opens into the clutch housing 1. When the clutch housing 3 rotates the cooling and lubricating oil is detected by the blades 9 and through the oil channel 10 into the Encouraged housing of the internal combustion engine, not shown.

Zwischen dem Kupplungsgehäuse i und der Brennkraftmaschine ist ein ölfreies Zwischengehäuse 12 mit einer Belüftungsöffnung 13 angeordnet. In dem Zwischengehäuse 12 läuft ein Anlasserzahnrad 14 um, das von einem normalen, nicht ölgeschützten Anlasser betätigt werden kann.Between the clutch housing i and the internal combustion engine is a Oil-free intermediate housing 12 with a ventilation opening 13 is arranged. In the intermediate housing 12 revolves around a starter gear 14 that is driven by a normal, non-oil-protected Starter can be operated.
