Description
Zweiteiliger Kolben für. Brennkraftmaschinen Die Erfindung betrifft eine ,Verbesserung des zweiteiligen Kolbens für Brennkraftm,aschinen nach Patent 596482 nach der Richtung, den Kopfteil aus einem Stoff hoher Wärmeleitfähigkeit (Leichtmetall) .gegenüber dem Schaft aus verschleißfestem Stoff, z. B. Grauguß, noch weiter auszusteifen und die Wärmeabführung durch den Kolben zu verbessern. Diese Wirkung wird dadurch erreicht, daß der Schaft aus zwei die Schaftenden bildenden Ringen aus verschleißfestem Stoff besteht, die mit den Verstärkungsringen der Bolzenaugen und mit einem Tragring des Kolbenkopfes durch die Vergußansätze zu .einem starren Gerippe vereinigt sind.Two-part piston for. Internal combustion engines The invention relates to an improvement of the two-part piston for Brennkraftm, aschinen according to patent 596482 according to the direction, the head part made of a material of high thermal conductivity (light metal). B. cast iron, to stiffen even further and to improve the heat dissipation through the piston. This effect is achieved in that the shaft consists of two rings made of wear-resistant material which form the shaft ends and which are combined with the reinforcing rings of the bolt eyes and with a support ring of the piston head through the casting lugs to form a rigid framework.
Auf der Zeichnung sind mehrere Ausführungsbeispiele eines zweiteiligen Kolbens nach der Erfindung dargestellt.In the drawing are several embodiments of a two-part Piston shown according to the invention.
Fig. i ist ein axialer Schnitt senkrecht zur Achse der Kolbenbolzen der ersten Ausführungsform; Fig. 2 ist ein axialer Schnitt nach Linie II-II in Fig. i ; Fig. 3 ist die zu Fig. i gehörige Unteransicht des Kolbens; Fig. 4 ist ein Schnitt nach Linie IV- IV in Fig. i ; Fig. 5 zeigt im Teilschnitt durch den Kopfteileine weitere Ausführungsform der Armierung des Kopfteiles.Fig. I is an axial section perpendicular to the axis of the piston pin the first embodiment; Fig. 2 is an axial section along line II-II in Fig. i; Figure 3 is the bottom plan view of the piston associated with Figure i; Fig. 4 is a section along line IV-IV in Fig. i; Fig. 5 shows a partial section through the head part Another embodiment of the reinforcement of the head part.
Bei allen Ausführungsformen besteht der Kolben aus einem Gerippe aus verschleißfestem Baustoff, z. B. Grauguß, der mit Leichtmetall umgossen ist. Gemäß Fig. i bis besteht das Gerippe aus den Ringen 1, 2 und 3, die durch Vergußansätze ia, 2a, 3a miteinander in starrer Verbindung stehen. Diese Vergußansätze liegen in gleichem Abstand von der Kolbenachse in parallelen Ebenen senkrecht zur Achse der Bolzenaugen 6 (Fig. 2) und laufen in den Ringen 4 aus, die zur Versteifung der Bolzenaugen 6 dienen. Die Vergußansätze 1a laufen in Querrippen 8 des Ringes i aus, der im Kolbenkopf liegt. Sie versteifen die Brücke zwischen Kolbenboden und Bolzenaugen und verhindern so eine Verformung der Bolzenaugen. Der Ring i dient zur Aufnahmeeines oder mehrerer Kolbenringe. Der Raum zwischen den Kolbenringen 2, 3 des Schaftes ist durch eine Zylinder ; aus Leichtmetall ausgefüllt, der mit den Bolzenaugen 6 ein Gußstück bildet. Der Zylinder 7 kann auch geschlitzt sein. Die Ringe 2, 3 entsprechen dem verschleißfesten Schaft im Sinne des Patents 596482. Der Zylinder 7 aus Leichtmetall verbessert die Wärmeabführung und bewirkt damit eine Verminderung des ölverbrauchs.In all embodiments, the piston consists of a framework made of wear-resistant building material, e.g. B. gray cast iron, which is encapsulated with light metal. According to FIGS. 1 to 3, the framework consists of the rings 1, 2 and 3, which are rigidly connected to one another by potting shoulders ia, 2a, 3a. These potting approaches are equidistant from the piston axis in parallel planes perpendicular to the axis of the bolt eyes 6 (FIG. 2) and terminate in the rings 4, which serve to stiffen the bolt eyes 6. The potting approaches 1a run out in transverse ribs 8 of the ring i, which lies in the piston head. They stiffen the bridge between the piston crown and the pin eyes and thus prevent the pin eyes from being deformed. The ring i serves to accommodate one or more piston rings. The space between the piston rings 2, 3 of the shaft is provided by a cylinder; Filled out of light metal, which forms a casting with the bolt eyes 6. The cylinder 7 can also be slotted. The rings 2, 3 correspond to the wear-resistant shaft in the sense of patent 596482. The cylinder 7 made of light metal improves heat dissipation and thus reduces oil consumption.
Bei der Ausführungsform nach Fig.5 ist der Tragring i im Kolbenkopf zu einem vollen Kolbenboden ausgebildet. Im übrigen entspricht die Ausführungsform der nach Fig. i bis 4.In the embodiment according to FIG. 5, the support ring i is in the piston head formed into a full piston crown. Otherwise the embodiment corresponds the one according to Fig. i to 4.
