Description

Die Erfindung betrifft Kolben für Kraftmaschinen, insbesondere Verbrennungskraftmaschinen mit Kugelgelenk zum Anschluß der Pleuelstange. Bei bekannten Kolben dieser Art sind radiale Rippen zwischen dem Kolbenkörper und der im Kblben festen Kugellagerhälfte vorgesehen, um diese Lagerhälfte mit dem Kolbenkörper zu verbinden.The invention relates to pistons for power machines, in particular internal combustion engines with ball joint for connecting the connecting rod. With known piston this Type are radial ribs between the piston body and the ball bearing half that is fixed in the piston provided to connect this bearing half to the piston body.

Erfindungsgemäß wird ein derartiger KoI-ben so ausgebildet, daß die Rippen zwischen dem Kugellager und dem Kolbenboden eine Aussparung für den freien Luftdurchtritt offen lassen. Hierdurch wird eine wirksame Kühlung des Lagers, das vom Kolbenträger fast isoliert ist, erzielt; denn die vom Kolben hervorgerufenen Luftströmungen können das Verbindungsgelenk allseitig umspülen.According to the invention such a KoI-ben is formed so that the ribs between the ball bearing and the piston head a recess for the free passage of air leave open. This ensures effective cooling of the bearing, which is carried by the piston carrier is almost isolated, scored; because the air currents created by the piston can do that Rinse the connecting joint on all sides.

Auf der Zeichnung bedeutet 1 den Kolbenkörper, der im wesentlichen aus einem hohlenIn the drawing, 1 denotes the piston body, which consists essentially of a hollow

Zylinder besteht, und oben durch den Boden 2 abgeschlossen ist. Innen im Kolben liegt nahe dem Boden 2 konachsial zum Kolbenkörper das Lager 3, das mit dem Kolbenkörper durch vier seitliche Rippen 4 verbunden ist. Alle bisher aufgezählten Teile werden vorzugsweise als ein einziges Gußstück hergestellt. Das Lager 3 besitzt einen halbkugelförmigen Boden und nimmt mit diesem den Kugelzapfen 5 der Schubstange 6 auf. Der Kugelzapfen 5 wird durch eine kugelig angeordnete Mutter 7, die in das Lager 3 eingeschraubt ist, und mit einer mittleren Bohrung 8 für den Durchgang und zur Ermöglichung der Schwingung der Schubstange versehen ist, festgehalten. Die Mutter 7 wird durch einen Ring 10 in ihrer Lage festgehalten. Der Ring kann auf irgendeine Weise gesichert werden, z. B. mittels eines Stiftes 11, der den Flansch des Ringes mit dem Flansch des Lagers verbindet.Cylinder consists, and is closed at the top by the bottom 2. Lies inside the piston near the bottom 2, the bearing 3, conaxially to the piston body, which is connected to the piston body is connected by four lateral ribs 4. All parts listed so far are preferred manufactured as a single casting. The bearing 3 has a hemispherical shape Floor and takes on the ball stud 5 of the push rod 6 with this. The ball stud 5 is arranged by a spherical Nut 7, which is screwed into the bearing 3, and with a central hole 8 for the passage and to enable the vibration of the push rod is recorded. The mother is 7 held in place by a ring 10. The ring can be in any way be secured, e.g. B. by means of a pin 11 which connects the flange of the ring to the flange of the camp connects.

Zwiischen dem Kolbenboden und der Lagerhälfte 3 ist eine Aussparung 12 vorgesehen, und zwar in sämtlichen Rippen 4. Sie dient, wie eingangs erwähnt, dazu, einen Luftumlauf um das Lager zwecks Kühlung zu ermöglichen. A recess 12 is provided between the piston head and the bearing half 3, namely in all ribs 4. As mentioned at the beginning, it serves to circulate air to allow the warehouse for cooling.
