Abstract
Brennkraftmaschine mit einer Unterdruckpumpe und mit einem Kurbelgehäuse, in dem eine Kurbelwelle drehbar gelagert ist und mit einem Zylinderkopf, in dem zwei Nockenwellen drehbar gelagert sind, wobei die Nockenwellen mittels Antriebsrädern über ein Endloszugmittel über ein Abtriebsrad der Kurbelwelle antreibbar sind, wobei die Unterdruckpumpe am Zylinderkopf zwischen den Nockenwellen innerhalb des Endloszugmittels angeordnet ist. Durch die erfindungsgemäße Ausgestaltung der Brennkraftmaschine wird bisher ungenutzter Bauraum genutzt.Internal combustion engine with a vacuum pump and with a crankcase, in which a crankshaft is rotatably mounted and with a cylinder head in which two camshafts are rotatably mounted, wherein the camshafts by means of drive wheels via a endless traction means via a driven gear of the crankshaft can be driven, wherein the vacuum pump on the cylinder head is disposed between the camshafts within the endless draw means. The inventive design of the internal combustion engine previously unused space is used.

In order to eliminate electrical contact problems, the electrical connection of the vacuum pump according to
Die Ausgestaltung gemäß Patentanspruch 6 erleichtert den Anschluss von Unterdruckverbrauchern wesentlich. The embodiment according to claim 6 facilitates the connection of vacuum consumers significantly.
Die Ausgestaltung gemäß Patentanspruch 7 ist eine bevorzugte Ausführungsform, bei der die Abluft der Unterdruckpumpe schlauchlos ins Innere der Brennkraftmaschine, besonders bevorzugt in den Endloszugmittelschacht, geführt wird und dort der Schmiermittelabscheidung zugeführt wird. The embodiment according to claim 7 is a preferred embodiment, in which the exhaust air of the vacuum pump tubeless into the interior of the internal combustion engine, particularly preferably in the Endloszugmittelschacht, is guided and there the lubricant separation is supplied.
Bevorzugt ist das Endloszugmittel gemäß Patentanspruch 8 eine Kette, wie beispielsweise eine Zahn- oder eine Rollenkette oder ein Zahnriemen. Preferably, the endless draw means according to
Im Folgenden ist die Erfindung anhand von zwei Figuren näher erläutert. In the following the invention is explained in more detail with reference to two figures.
Im Folgenden gelten in den
Erfindungsgemäß ist die Unterdruckpumpe
Besonders bevorzugt sind die Antriebsräder
Weiterhin ist die Unterdruckpumpe
In einer Weiterbildung der Erfindung ist die Unterdruckpumpe 2 bevorzugt eine elektrische Unterdruckpumpe, an die ein elektrischer Anschluss 9 nach außen angeordnet ist, d. h. aus dem Schmiermittelnebel im Endloszugmittelschacht
Ebenfalls bevorzugt ist ein Unterdruckanschluss der Unterdruckpumpe
Weiter bevorzugt wird die Abluft der Unterdruckpumpe
Als Endloszugmittel
Somit ergeben sich folgende Vorteile für die erfindungsgemäße Ausgestaltung:
- – Nutzung des Bauraums im sog. Kettendreieck, innerhalb des Endlos zugmittels
7 , - – Anschluss der Unterdruckpumpe
2 an eine bestehende Schmiermittel versorgung, - – Elektrischer Anschluss
9 außenliegend (trocken), - – Unterdruckanschluss außenliegend (einfache Montage),
- – Befestigung direkt am Zylinderkopf oder am bevorzugt einstückig
angegossenen Endloszugmittelschacht 10 .
- - Use of space in the so-called chain triangle, within the endless traction means
7 . - - Connection of the vacuum pump
2 to an existing lubricant supply, - - Electrical connection
9 outboard (dry), - - negative pressure connection outside (easy assembly),
- - Attachment directly to the cylinder head or on preferably integrally molded
Endloszugmittelschacht 10 ,
