Description
Zweiteiliger Kolben für Brennkraftmaschinen Das Hauptpatent 595 591 löst die Aufgabe, die Verbindung zwischen Kopfteil und Schaft eines zweiteiligen Kolbens durch Vergießen der Teile miteinander nach der Richtung zu verbessern, daß ein Verlagern oder Schrägstellen des Kopfteiles zum Schaft durch die horizontale Komponente der Pleuelstangenkrä,fte und eine Deformierung des Schaftteiles durch die größere Wärmeausdehnung des Kopfteiles ausgeschlossen ist. Diese Wirkung wird dadurch erreicht, daß die Vergußansätze radial zur Achse des Kolbens nachgiebig sind und in axialer Richtung den Kopfteil kippsicher stützen. Bei allen Ausführungsformen .zach dem Hauptpatent sind die Vergußansätze am Schaftteil des Kolbens angeordnet. Die vorliegende Erfindung zeigt eine andere Ausführungsform des Erfindungsgedankens. Sie besteht darin, daß die Vergußansätze am Kopfteil angegossen sind und als frei tragende, in den Schaftteil. eintretende Stützen um die am Schaft sitzenden Bolzenaugen herumgegossen sind.Two-part piston for internal combustion engines The main patent 595 591 solves the task of connecting the head part and shaft of a two-part To improve the piston by potting the parts together according to the direction that a shifting or inclination of the head part to the shaft through the horizontal Component of the connecting rod forces and a deformation of the shaft part the greater thermal expansion of the head part is excluded. This effect will achieved in that the casting lugs are radially resilient to the axis of the piston and support the head part in the axial direction so that it does not tip over. In all embodiments .zach the main patent, the potting approaches are arranged on the skirt part of the piston. The present invention shows another embodiment of the inventive concept. It consists in that the potting approaches are cast on the head part and as free load-bearing, in the shaft part. entering supports around the bolt eyes on the shaft are poured around.
Auf der Zeichnung ist eine Ausführungsform eines zweiteiligen Kolbens nach der Erfndung dargestellt.In the drawing is an embodiment of a two-part piston shown according to the invention.
Fig. i ist ein Längsschnitt durch die Achse des Kolbenbolzens, Fig. 2 eiri Längsschnitt senkrecht dazu. Wie beim Hauptpatent bezeichnet i den Kopfteil des Kolbens aus einem Stoff hoher Wärmeleitfähigkeit, z. B. Leichtmetall, 2 den zylindrischen Schaftteil aus einem Metall hoher Verschleißfestigkeit, z. B. Grauguß. Die Verbindung der beiden Teile erfolgt durch zwei Stützeng, die an dem Boden des Kopfteiles angegossen sind, im übrigen aber frei tragend in den Schaft 2 hineinragen, so daß sie in radialer Richtung nachgiebig sind. Die Bolzenaugen 3' sind an den Schaft 2 angegossen und mit den Augen 3 der Stützeng vergossen. Die Sicherung gegen Kippen erfolgt durch eine oder mehrere radiale Zungen i o der Bolzenaugen, die von den Stützeng umschlossen sind. Die Stützwirkung wird durch die Form der Stützeng erhöht, die am Rand des Kopfteiles breit ausladen und nach den Bolzenaugen hin zusammenlaufen.Fig. I is a longitudinal section through the axis of the piston pin, Fig. 2 a longitudinal section perpendicular to it. As with the main patent, i denotes the head part of the piston made of a material of high thermal conductivity, e.g. B. light metal, 2 den cylindrical shaft part made of a metal of high wear resistance, e.g. B. gray cast iron. The two parts are connected by two supports that are attached to the bottom of the Head part are cast, but otherwise protrude freely into the shaft 2, so that they are compliant in the radial direction. The bolt eyes 3 'are on the Shank 2 cast on and potted with the eyes 3 of the supports. The protection against Tilting takes place through one or more radial tongues i o of the bolt eyes, which of the Stützeng are enclosed. The support effect is determined by the shape of the supports increased, which overhang broadly at the edge of the head part and converge towards the bolt eyes.
