Description

Die Erfindung bezieht sich auf eine Zündverteileranordnung an Brennkraftmaschinen, bei der der Zündverteiler am Gehäuse der Brennkraftmaschine befestigt ist und von einer Nockenwelle der Brennkraftmaschine angetrieben wird, die mit einem antriebsseitigen Ende über Antriebsmittel mit der Kurbelwelle der Brennkraftmaschine verbunden ist.The invention relates to an ignition distributor arrangement on internal combustion engines, in which the ignition distributor is fastened to the housing of the internal combustion engine and is driven by a camshaft of the internal combustion engine, which is connected at its drive end to the crankshaft of the internal combustion engine via drive means.

Da bei Viertakt-Brennkraftmaschinen der Verteilerläufer des Zündverteilers mit Nockenwellendrehzahl dreht, ist es naheliegend, den Antrieb für den Verteilerläufer von der Nockenwelle selbst abzunehmen. So ist es z.B. durch die DE-OS 26 30 220 bekannt, den Zündverteiler senkrecht zur Nockenwelle am Gehäuse der Brennkraftmaschine zu befestigen und von der Nockenwelle über einen Zahnradwinkeltrieb anzutreiben. Neben der relativ großen Bauhöhe weist eine derartige Zündverteileranordnung den weiteren Nachteil einer aus dem Zahnradwinkeltrieb resultierenden großen Zündzeitpunkttoleranz auf.Since in four-stroke internal combustion engines the distributor rotor of the ignition distributor rotates at the camshaft speed, it makes sense to remove the drive for the distributor rotor from the camshaft itself. So it is e.g. known from DE-OS 26 30 220 to fix the ignition distributor perpendicular to the camshaft on the housing of the internal combustion engine and to drive it from the camshaft via a gear angle drive. In addition to the relatively large overall height, an ignition distributor arrangement of this type has the further disadvantage of a large ignition timing tolerance resulting from the gearwheel angle drive.

Darüber hinaus ist durch diese DE-OS 26 30 220 eine Zündverteileranordnung bekannt, bei der der Zündverteiler achsgleich mit der Nockenwelle auf der der Nockenwellenantriebsseite abgewandten Seite der Nockenwelle und somit im Bereich der Spritzwand der Kraftfahrzeug-Karosserie am Gehäuse der Brennkraftmaschine befestigt ist und direkt durch die Nockenwelle angetrieben wird. Diese Zündeverteileranordnung weist aufgrund des Wegfalls des Zahnradspiels des Zahnradwinkeltriebs den Vorteil einer verringerten Zündzeitpunkttoleranz auf. Da jedoch viele Fahrzeuge alternativ mit 4- oder 6-Zylinder-Brennkraftmaschinen ausrüstbar sind und dabei die Anflanschung der Brennkraftmaschine an das Getriebe für beide Alternativen unverändert in derselben Ebene verbleiben soll, wird die 4-Zylinder-Brennkraftmaschine möglichst dicht an der Spritzwand angeordnet, um im vorderen Teil des Brennkraftmschinenraumes ausreichend Platz für die längere 6-Zylinder-Brennkraftmaschine zu haben. Dies bringt jedoch zwangsläufig den Nachteil mit sich, daß für die Anordnung des Zündverteilers an dem Gehäuse der Brennkraftmaschine im Bereich der Spritzwand nur ein geringer Bauraum verbleibt.In addition, an ignition distributor arrangement is known from this DE-OS 26 30 220, in which the ignition distributor is attached coaxially with the camshaft on the side of the camshaft facing away from the camshaft drive side and thus in the area of the bulkhead of the motor vehicle body on the housing of the internal combustion engine and directly by the camshaft is driven. This ignition distributor arrangement has the advantage of a reduced ignition timing tolerance due to the elimination of the gear play of the gear angle drive. However, since many vehicles alternatively with 4- or 6-cylinder Internal combustion engines can be equipped and the flange connection of the internal combustion engine to the transmission should remain unchanged in the same plane for both alternatives, the 4-cylinder internal combustion engine is arranged as close as possible to the bulkhead in order to provide sufficient space in the front part of the internal combustion engine room for the longer 6-cylinder - to have an internal combustion engine. However, this inevitably has the disadvantage that only a small installation space remains for the arrangement of the ignition distributor on the housing of the internal combustion engine in the region of the bulkhead.

Aufgabe der Erfindung ist es, eine Zündverteileranordnung bei in Fahrzeuglängsrichtung eingebauten Brennkraftmaschinen zu schaffen, bei der der Zündverteiler eine geringe Zündzeitpunkttoleranz aufweist und aufgrund seiner räumlichen Anordnung die alternative Verwendung verschieden großer Brennkraftmaschinen vom Zündverteiler unbeeinflußt bleibt.The object of the invention is to provide an ignition distributor arrangement in internal combustion engines installed in the vehicle longitudinal direction, in which the ignition distributor has a low ignition timing tolerance and, due to its spatial arrangement, the alternative use of differently sized internal combustion engines remains unaffected by the ignition distributor.

Erfindungsgemäß wird diese Aufgabe durch die gekennzeichneten Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the characterized features of patent claim 1.

Weitere Merkmale der Erfindung beinhalten die Unteransprüche.Further features of the invention include the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen im wesentlichen darin, daß durch die nockenwellenantriebsseitige Anordnung des Zündverteilers am Gehäuse der Brennkraftmaschine die verschiedensten Zündverteiler verwendet werden können, ohne daß die Lage der Brennkraftmaschine gegenüber der Spritzwand verändert werden muß. Dieser Vorteil kommt insbesondere bei der Verwendung von Fliehkraftreglern mit Unterdurck und Fliehkraftverstellung zum tragen, die eine beträchtliche Baulänge aufweisen. Darüberhinaus ist es durch die erfindungsgemäße Zündverteileranordnung möglich, einen einzigen Brennkraftmaschinentyp mit einer festgelegten ölwannenkontur und/oder einer ölpumpenanordnung mit einer im ölsumpf der Brennkraftmaschine angeordneten ölpumpe in verschiedenen Fahrzeugtypen zu verwenden, ohne daß dadurch die Einbauverhältnisse der Brennkraftmaschine zu Rahmenstrukturen des Fahrzeuges beeinflußt werden.The advantages achieved by the invention consist essentially in the fact that, due to the camshaft drive-side arrangement of the ignition distributor on the housing of the internal combustion engine, a wide variety of ignition distributors can be used without having to change the position of the internal combustion engine relative to the bulkhead. This advantage is particularly important when using centrifugal governors with underpressure and centrifugal force adjustment, which have a considerable overall length. In addition, the ignition distributor arrangement according to the invention makes it possible to use a single type of internal combustion engine with a defined oil pan contour and / or an oil pump arrangement with an oil pump arranged in the oil sump of the internal combustion engine in different vehicle types without the installation conditions of the internal combustion engine being influenced by the frame structures of the vehicle.
