Abstract
Description
Die Erfindung betrifft einen Kolben für Hubkolbenbrennkraftmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a piston for reciprocating internal combustion engines according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zu Grunde, die Schmierung und Kühlung eines gattungsgemäßen Kolbens und eines Pleuellagers zu verbessern, indem das aus dem Kühlraum zurückströmende Kühlöl gezielt an die Bedarfsstellen herangeführt wird. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is the task Basically, the lubrication and cooling a generic piston and to improve a connecting rod bearing, by targeted from the cooling space flowing back cooling oil is brought to the needs. It is according to the invention solved by the features of claim 1. Further advantageous embodiments emerge from the dependent claims.
Nach der Erfindung sind in dem Kolbenoberteil, in dem Kolbenschaft und/oder in der Pleuelstange Schmierölbohrungen vorgesehen, die mit einem Ende einem Rücklaufkanal zugewandt sind und an diesem Ende eine Auffangvorrichtung besitzen, auf die der Rücklaufkanal ausgerichtet ist. Dadurch wird das Kühlöl gezielt an die Lagerstellen und zu kühlenden Stellen der Antriebsteile geleitet und möglichst viel von dem aus dem Kühlraum austretenden Kühlöl aufgefangen und genutzt. Somit wird eine sichere Kühlung und Schmierung gewährleistet.According to the invention, in the piston upper part, in the piston skirt and / or in the connecting rod lubricating oil holes provided, which face with one end to a return channel and at this end have a collecting device to which the Return channel is aligned. As a result, the cooling oil is targeted to the bearings and to be cooled Passed the drive parts and as much as possible from the refrigerator collected cooling oil collected and used. This ensures safe cooling and lubrication.
Die Durchbrüche im Shakerblech dienen zur Regulierung und Leitung des Kühlölstroms durch den Kühlraum. Die Rücklaufkanäle, die zweckmäßigerweise als Düsen ausgestaltet sind, lei ten das zurückströmende Öl sicher über den kritischen Spalt zwischen dem Kolbenoberteil und dem Kolbenschaft, so dass nicht zu befürchten ist, dass zu viel Öl durch den Spalt auf die Außenseite des Kolbens gelangt.The breakthroughs in the shaker plate serve to regulate and management of cooling oil flow through the fridge. The return channels, the expediently as nozzles are designed, the oil flowing back safely across the critical gap between the piston upper part and the piston skirt so that there is no fear that too much oil through the gap on the outside of the piston passes.
Die Rücklaufkanäle und Düsen können günstig durch Prägen, Tiefziehen oder Stanzen des Shakerblechs gefertigt werden. In vorteilhafter Weise wird vor dem Rücklaufkanal zum Kühlraum hin eine Vertiefung vorgesehen, in der sich ein gewisser Vorrat an Kühlöl sammeln kann.The return channels and nozzles can be cheap by embossing, deep drawing or punching the shaker plate are made. In an advantageous manner Way, before the return channel to the refrigerator towards a depression provided in a certain supply to collect cooling oil can.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages arise the following description of the drawing. In the drawing is an embodiment represented the invention. The drawing, the description and the Claims included numerous features in combination. The skilled person will become the characteristics appropriately also individually consider and summarize to meaningful further combinations.
