Abstract
Description
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere für ein Kraftfahrzeug, mit
wenigstens drei V-förmig zueinander angeordneten Zylinderreihen, gemäß dem
Oberbegriff des Anspruchs 1.The invention relates to an internal combustion engine, in particular for a motor vehicle
at least three rows of cylinders arranged in a V-shape relative to one another, according to the
Preamble of
Bei derartigen Brennkraftmaschinen ergibt sich das Problem, daß ein Abtrieb von einer Kurbelwelle zum Antrieb jeweiliger Nockenwellen der Zylinderreihen sehr sch wierig zu realisieren ist. Bisher bekannte Abtriebe bei derartigen Brennkraftmaschinen sind stirnseitig angeordnet, dies hat jedoch den Nachteil, daß sich eine große Baulänge der Brennkraftmaschine ergibt. Bei immer kleiner werdenden Bauräumen, beispielsweise in Kraftfahrzeugen, stößt diese Anordnung insbesondere bei großer Zylinderzahl jedoch schnell an Grenzen.In such internal combustion engines, the problem arises that an output of one Crankshaft for driving the respective camshafts of the cylinder rows is very difficult is to be realized. Previously known outputs in such internal combustion engines are arranged at the end, but this has the disadvantage that there is a large overall length Internal combustion engine results. With installation spaces becoming smaller and smaller, for example in Motor vehicles, however, encounter this arrangement especially when there are a large number of cylinders quickly to limits.
Aus der DE 39 378 587 A1 ist es bei einer Brennkraftmaschine mit zwei V-förmig zueinander angeordneten Zylinderreihen bekannt, daß das Zylinderkurbelgehäuse einen quer zur Kurbelwellen-Drehachse verlaufenden, im wesentlichen senkrechten, durchgehenden Schacht aufweist. Innerhalb des Schachtes sind entsprechende Vorkehrungen zum Anschluß einer Abtriebswelle und eines Getriebegehäuses vorgesehen. Die Kurbelwelle ist innerhalb des Schachtes mit einem Kettenrad versehen, über welches Nockenwellen angetrieben werden. Hierbei ist jedoch nachteilig, daß für den Anschluß des Getriebes am Mittenabtrieb ein äußerst breiter Schacht notwendig ist. Diese Anordnung ist bereits bei drei Zylinderreihen, wegen der mechanischen Schwächung des Zylinderkurbelgehäuses durch den Schacht nicht mehr möglich. Ferner befinden sich bei der Brennkraftmaschine gemäß DE 39 378 587 A1 Abtriebe für Nebenaggregate an beiden Stirnseiten des Zylinderkurbelgehäuses, wodurch sich eine Einbaulänge ungünstig erhöht.From DE 39 378 587 A1 it is in an internal combustion engine with two V-shaped mutually arranged rows of cylinders known that the cylinder crankcase one running essentially perpendicular to the axis of rotation of the crankshaft, has continuous shaft. Corresponding are inside the shaft Precautions for connecting an output shaft and a gearbox intended. The crankshaft is provided with a sprocket inside the shaft, via which camshafts are driven. However, it is disadvantageous that for an extremely wide shaft is necessary to connect the gearbox to the center drive. This arrangement is already with three rows of cylinders, because of the mechanical Weakening of the cylinder crankcase by the shaft is no longer possible. Further are in the internal combustion engine according to DE 39 378 587 A1 drives for Auxiliary units on both ends of the cylinder crankcase, resulting in a Installation length unfavorably increased.
Eine Brennkraftmaschine mit drei V-förmig zueinander angeordnete Zilinderreihen ist aus der US 1535084 bekannt.An internal combustion engine with three V-shaped arranged to each other Zilinderreihen is known from US 1535084.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine verbesserte Brennkraftmaschine der obengenannten Art zur Verfügung zu stellen, wobei die obengenannten Nachteile überwunden werden und ein kompakter und bauraumsparender Abtrieb von einer Kurbelwelle zum Antrieb von Nockenwellen jeweiliger Zylinderreihen realisierbar ist.The present invention is therefore based on the object of an improved To provide internal combustion engine of the type mentioned above, the the disadvantages mentioned above and a compact and Space-saving output from a crankshaft for driving camshafts respective cylinder rows can be realized.
Diese Aufgabe wird erfindungsgemäß durch eine Brennkraftmaschine der o.g. Art mit
den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen
der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by an internal combustion engine of the above. Kind with
solved the features characterized in
Dazu ist es erfindungsgemäß vorgesehen, daß genau eine der Zylinderreihen in zwei Zylinderanordnungen derart unterteilt ist, daß eine Kurbelwelle über einen vorbestimmten Abschnitt freigelegt ist, wobei an dem freigelegten Abschnitt der Kurbelwelle ein Mittenabtrieb für wenigstens eine Nockenwelle und Nebenaggregate angeordnet ist, wobei ferner von jeder Zylinderanordnung der geteilten Zylinderreihe benachbart und im wesentlichen parallel zu einer Teilungsebene jeweils wenigstens ein Steg zu jeder benachbarten Zylinderreihe ausgebildet ist.For this purpose, it is provided according to the invention that exactly one of the cylinder rows in two Cylinder arrangements is divided such that a crankshaft over a predetermined Section is exposed, with the exposed section of the crankshaft Center drive for at least one camshaft and auxiliary units is arranged, wherein further from each cylinder arrangement of the divided cylinder row adjacent and in essentially parallel to a division plane, at least one web to each adjacent row of cylinders is formed.
Dies hat den Vorteil, daß mit einer Teilung einer einzigen Zylinderreihe ein Mittenabtrieb für jeweilige Nockenwellen aller Zylinderreihen und gleichzeitig ein Antrieb für Nebenaggregate realisierbar ist, ohne alle Zylinderreihen teilen zu müssen. Gleichzeitig ist eine hohe mechanische Stabilität der Brennkraftmaschine sichergestellt.This has the advantage that with a division of a single row of cylinders, a center drive for respective camshafts of all cylinder rows and at the same time a drive for Auxiliary units can be realized without having to divide all cylinder rows. simultaneously a high mechanical stability of the internal combustion engine is ensured.
Zweckmäßigerweise definiert die Teilung der geteilten Zylinderreihe eine Teilungsebene, welche senkrecht zu einer Drehachse einer Kurbelwelle der Brennkraftmaschine angeordnet ist.The division of the divided cylinder row expediently defines a division plane, which is perpendicular to an axis of rotation of a crankshaft of the internal combustion engine is arranged.
In einer besonders bauraumsparenden Ausführungsform ist die Teilung der Zylinderreihe mittig in zwei symmetrische Zylinderanordnungen ausgebildet.The division of the cylinder row is in a particularly space-saving embodiment formed in the center in two symmetrical cylinder arrangements.
Zweckmäßigerweise sind vier Stege vorgesehen und die jeweiligen Zylinderreihen in Closed Deck-Bauweise ausgebildet.Four webs are expediently provided and the respective rows of cylinders in Closed deck construction.
Zum Antrieb der Nebenaggregate durch den einzigen in der geteilten Zylinderreihe angeordneten Abtrieb von einer Kurbelwelle weist in besonders bevorzugter Weise wenigstens ein Steg eine Durchbrechung zur Durchführung eines Antriebs für ein Nebenaggregat auf.To drive the auxiliary units through the only one in the divided cylinder row arranged output from a crankshaft points in a particularly preferred manner at least one web has an opening for carrying out a drive for Auxiliary unit on.
Zum gleichzeitigen Antrieb von jeweiligen Wasserpumpen, welche jeweilige Zylinderanordnungen bzw. Zylinderreihen bzw. Zylinderreihenteile mit Kühlwasser versorgen, ist in besonders vorteilhafter Weise benachbart zu einer Teilungsebene der geteilten Zylinderreihe zwischen dieser und einer benachbarten ungeteilten Zylinderreihe wenigstens eine Befestigungsvorrichtung für wenigstens eine Wasserpumpe ausgebildet. Dies erspart zusätzliche Abtriebe für die Wasserpumpe an anderer Stelle, wodurch Bauraum und Gewicht eingespart ist.For the simultaneous drive of respective water pumps, which respective Cylinder arrangements or cylinder rows or cylinder row parts with cooling water supply, is in a particularly advantageous manner adjacent to a division level of divided row of cylinders between this and an adjacent undivided row of cylinders formed at least one fastening device for at least one water pump. This saves additional drives for the water pump elsewhere, which means Space and weight is saved.
Beispielsweise ist die geteilte Zylinderreihe die mittige Zylinderreihe. Hierdurch ist von dem Mittenabtrieb der mittigen, geteilten Zylinderreihe in vorteilhafter Weise ein einziger Abtrieb zum Antrieb sowohl der Nockenwelle der mittigen Zylinderreihe als auch der beiden benachbarten Zylinderreihen realisierbar.For example, the split row of cylinders is the central row of cylinders. This is from the center output of the central, divided row of cylinders is advantageously a single one Output to drive both the camshaft of the central row of cylinders and the two neighboring cylinder rows can be realized.
Eine besonders bauraumsparende Anordnung zum Einbau in einen Motorraum eines Kraftfahrzeuges erzielt man dadurch, daß die drei Zylinderreihen derart zueinander V-förmig angeordnet sind, daß eine äußere Zylinderreihe in einer Betriebsstellung der Brennkraftmaschine im wesentlichen waagrecht angeordnet ist.A particularly space-saving arrangement for installation in an engine compartment Motor vehicle is achieved in that the three rows of cylinders to each other Are arranged in a V-shape that an outer row of cylinders in an operating position Internal combustion engine is arranged substantially horizontally.
Eine besonders gute Kühlwasserversorgung der Zylinderreihen erzielt man dadurch, daß zwei Wasserpumpen vorgesehen sind, wobei jede Wasserpumpe jeweils eine außen liegende Zylinderreihe und eine Zylinderanordnung der geteilten Zylinderreihe mit Kühlwasser versorgt. A particularly good supply of cooling water to the cylinder banks is achieved in that Two water pumps are provided, with each water pump having an outside horizontal cylinder row and a cylinder arrangement of the divided cylinder row with Cooling water supplied.
In einer besonders bevorzugten Ausführungsform weist jede Zylinderreihe sechs Zylinder auf.In a particularly preferred embodiment, each row of cylinders has six cylinders on.
