Abstract
Description
Die Erfindung betrifft ein Kurbelgehäuse für eine Brennkraftmaschine mit seitlichen Gehäusewänden zwischen denen sich Kurbelwellenlager in Kurbelgehäusequerrichtung erstrecken, die aus kurbelgehäusefesten Lagerstühlen und von diesen durch eine Lagertrennebene getrennten Lagerdeckeln bestehen, die an den Lagerstühlen mittels Lagerschrauben befestigt sind, ferner mit einem von der Trennebene der Kurbelwellenlager aus sich zumindest im Verlauf der seitlichen Gehäusewände vorsetzenden und dabei die Lagerdeckel seitlich umschließenden Gehäuseunterteil, zwischen dessen Gehäuseseitenwänden und den Lagerdeckeln ein Spalt vorgesehen ist, der zur Verbindung der Lagerdeckeln mit dem Gehäuseunterteil mit Dämpfungswerkstoff gefüllt ist.The The invention relates to a crankcase for one Internal combustion engine with lateral housing walls between which crankshaft bearings in the crankcase transverse direction extend from the crankcase fixed bearing blocks and from these separated by a bearing separation plane bearing caps that exist at the camp chairs are fastened by means of bearing screws, also with one of the parting plane the crankshaft bearing out at least in the course of the lateral Preceding housing walls while the bearing cap laterally enclosing housing base, between the Housing side walls and the bearing caps a gap is provided, which is used to connect the Bearing caps with the lower housing part with damping material filled is.

Diese Maßnahme zur Geräuschdämpfung am Kurbelgehäuse ist mit einem erheblichen Bauaufwand verbunden. Außerdem ist die bekannte Maßnahme für eine nachträgliche Ausrüstung eines bestehenden Kurbelgehäuses nicht geeignet.These measure for noise reduction on crankcase is associated with a significant construction cost. Besides that is the known measure for one subsequent equipment an existing crankcase not suitable.
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Kurbelgehäuse derart weiter zu gestalten, dass mit vereinfachten baulichen Maßnahmen eine verbesserte Geräuschdämpfung und eine nachträglich Anwendung bei bestehenden Kurbelgehäusen erreicht wird.Of the Invention is based on the object, the known crankcase so continue to shape that with simplified structural measures a improved noise reduction and one after the other Application is achieved with existing crankcases.
Die Aufgabe ist erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst.The Task is inventively by the features specified in the characterizing part of claim 1 solved.
Die erfindungsgemäße Lösung hat den Vorteil, dass die Maßnahmen zur Geräuschdämpfung an dem Gehäuseunterteil und damit einem eigenständigen Bauteil vorgesehen sind. Damit ist es möglich, bestehende Kurbelgehäuse nachträglich mit dem erfindungsgemäßen Gehäuseunterteil auszurüsten und so auf einfache Weise die Geräuschdämpfung an bereits bestehenden Kurbelgehäusen zu verbessern.The inventive solution the advantage of that measures for noise reduction at the Housing bottom and thus an independent one Component are provided. This makes it possible to retrofit existing crankcase with the housing lower part according to the invention equip and so easy on the noise attenuation already existing crankcases to improve.
Ferner ist der Bauaufwand verringert, da die Lagerdeckel am Gehäuseunterteil angebracht sind und damit in einem Montagevorgang die Lagerdeckel zusammen mit dem Gehäuseunterteil am Kurbelgehäuse montiert werden können.Further the construction cost is reduced because the bearing cap on the housing base are mounted and thus together in a mounting operation, the bearing cap with the housing lower part on the crankcase can be mounted.
In einer Ausgestaltung der Erfindung ist es vorteilhaft, wenn das Gehäuseunterteil aus rahmenförmig mit einer Verbindungsfläche zur dichten Anlage am Kurbelgehäuse und einer weiteren Verbindungsfläche zum Anschluss einer Ölwanne ausgebildet ist.In An embodiment of the invention, it is advantageous if the lower housing part out of frame-shaped with a connection surface for tight contact with the crankcase and another interface for connecting an oil pan is trained.
Eine baulich einfache und sowohl kosten- als auch montagegünstige Ausführung wird gemäß Anspruch 3 dadurch erreicht, dass das Gehäuseunterteil als Ölwanne ausgebildet ist.A structurally simple and cost-effective as well as easy to install according to claim 3 achieved in that the lower housing part as an oil pan is trained.
Vorteilhaft ist es, wenn zur Geräuschdämpfung Ölwanne und Lagerdeckel gemäß Anspruch 6 ausgebildet sind. Hierdurch wird ebenfalls eine vereinfachte Montage erzielt, da mit der Montage der Lagerdeckel gleichzeitig die Ölwanne gegen das Kurbelgehäuse dichtend gedrückt wird.Advantageous it is, if for noise damping oil sump and Bearing cover according to claim 6 are formed. This will also simplify installation achieved, as with the mounting of the bearing cap at the same time the oil pan against the crankcase pressed tightly becomes.
Schließlich wird eine vorteilhafte Ausgestaltung für das Gehäuseunterteil beziehungsweise die Ölwanne erzielt, wenn diese Bauelemente zusätzlich mit einer Ölführungswand sowie einer Ölleitöffnung versehen sind, welche als Ölhobel zur Trennung des Schmierölanteils aus der vom Kurbeltrieb bewegten Luftwalze wirkt.Finally will an advantageous embodiment of the lower housing part or the oil pan achieved, if these components additionally with an oil guide wall and a Ölleitöffnung provided are, which as an oil planer for separating the lubricating oil content from the moving from the crank mechanism air roller acts.
