Die Erfindung bezieht sich auf die Lagerung von Kolbenbolzen, insbesondere von Kolbenbolzen für Kolben von Verbrennungskraftmaschinen· Derartige Lagerungen sind mit verschiedenartigen Problernen verbunden, da sie im allgemeinen schnell wechselnden, hohen Brücken bei beachtlichen Temperaturen ausgesetzt sind. Hierdurch bestehen Schwierigkeiten bei der Ölversorgung. Hinzu kommt in diesem Zusammenhang der Nachteil, daß der Kolbenbolzen keine rotierende Bewegung ausführt· Weiterhin sind die unterschiedlichen Wärmedehnungen des Kolbens und des Bolzens so aufzunehmen, daß das Ijagerspiel im Sinne einer Geräuschdämpfung, insbesondere bei hoher Temperatur, nicht zu groß wird· Andererseits darf es aber auch wegen der Preßgefahr bei extrem niederen * Temperaturen keinen zu kleinen Wert erreichen· Sine zusätzliche, nachteilige Bedingung für den Kolbenbolzen ist dadurch eingetreten, daß in jüngerer Zeit sogenannte Schrumpfpleuel Anwendung finden«, Hierbei führt der Kolbenbolzen entsprechend der Pleuelbewegung eine oszillierende Zwangsbewegung aus· Besonders nachteilig wirkt sich dieser Umstand beim Anlaufen stark unterkühlter Maschinen aus; in diesem Zustand ist in der Lagerung zuweilen überhaupt kein Spiel vorhanden. Bei der früher Üblichen LagerungThe invention relates to the bearing of piston pins, in particular of piston pins for pistons of internal combustion engines. Such bearings are associated with various problems, since they are generally exposed to rapidly changing, high bridges at considerable temperatures. As a result, there are difficulties with the oil supply. In addition, there is the disadvantage in this context that the piston pin does not perform any rotating movement.Furthermore, the different thermal expansions of the piston and the pin must be absorbed in such a way that the jogging play in terms of noise dampening, especially at high temperatures, does not become too great.On the other hand, it may but also because of the risk of compression at extremely low * temperatures, do not achieve a value that is too low This fact has a particularly disadvantageous effect when starting up strongly supercooled machines; in this state there is sometimes no play at all in the bearing. With the previously usual storage

des Bolzens im Pleuel mittels einer Bronzebüchse konnte sich. der Bolzen in derartigen Grenzfällen, in denen entweder die Schmierung oder das Spiel in den Bolzenaugen nicht mehr vorhanden war, in der Pleuelbüchse drehen, ohne daß die Bolzenaugen dadurch gefährdet wurden. Bei den sogenannten Preßpleuelstangen ist dies nicht mehr möglich.of the bolt in the connecting rod by means of a bronze bushing. the bolt in borderline cases in which either the There is no longer any lubrication or play in the bolt eyes was to turn in the connecting rod bushing without affecting the bolt eyes were endangered. This is the case with the so-called press connecting rods not possible anymore.
Zur Überwindung der vorstehend aufgezeigten. Probleme war es bisher notwendig, eine weitgehende Verfeinerung der Toleranzen, eine Verbesserung der Oberflächengüte sowie der Passung vorzunehmen. Abgesehen davon, daß damit eine außerordentliche Verteuerung der Bolzenlagerung verbunden ist, führen auch diese Maßnahmen insbesondere bei den genannten Schrumpfpleueln zu keiner generell befriedigenden lösung· r To overcome the above. Problems have hitherto made it necessary to largely refine the tolerances, improve the surface quality and the fit. Aside from being so exceptional increase in the price of the bolt bearing is connected, even these measures especially in the above Schrumpfpleueln no generally satisfactory solution * r
Der Erfindung liegt daher die Aufgabe zu Grunde, die aufgezeigten Probleme einer Bolzenlagerung, insbesondere von Brennkraftmaschinenkolben, mit einer einfachen Maßnahme zu beseitigen. Gelöst ist die erfindungsgemäße Aufgabe. dadurch, daß die Bolzenbohrungen im Kolben, die den Bolzen aufnehmen, oval ausgebildet sind, wobei die große Achse des Ovals quer zur. Längsachse des Kolbens zu liegen kommt· Durch die Erfindung gelingt es, nicht nur die eingangs erläuterten Probleme zu beseitigen, sondern es ist auch , möglich, bei der Herstellung der Kolbenbolzenlagerung deren Bearbeitungstoleranzen sowie die Oberflächengüte in normalen Grenzen zu halten. Weiterhin wird durch die Erfindung die EreßsicherheitThe invention is therefore based on the object of eliminating the identified problems of a pin mounting, in particular of internal combustion engine pistons, with a simple measure. The object according to the invention is achieved. in that the pin bores in the piston, which receive the pin, are oval, the major axis of the oval being transverse to the. Longitudinal axis of the piston comes to rest · The invention succeeds not only to eliminate the above-described problems, but it is also possible to maintain, in the production of piston pin bearing the machining tolerances and surface quality within normal limits. Furthermore, the erection security is achieved by the invention

Außerdem ermöglicht die ovale Kolbenbolzenlagerung nach der Erfindung automatisch ein günstiges Schmierstoffreservoir.\ and the running smoothness is improved, especially for deep and high limit temperatures is important. In addition, the oval piston pin bearing according to the invention enables automatic a cheap lubricant reservoir.
In den Abbildungen ist die Erfindung zeichnerisch erläutert. Sie Abbildung 1 zeigt einen Längsschnitt durch einen Kolben für Hubkolbenmaschinen· Die Abbildung 2 zeigt in vergrößerter Darstellung die erfindungsgemäße Ausbildung der Bolzenbohrungen im M Kolben·The invention is illustrated graphically in the figures. You Figure 1 shows a longitudinal section through a piston for reciprocating engines · Figure 2 shows an enlarged representation of the inventive design of the bolt holes in the pistons · M
Wie vor allem aus der Abbildung 2 hervorgeht, sind die Bohrungen für die Kolbenbolzen erfindungsgemäß oval ausgebildet, wobei die große Achse 2 des Ovals quer zur Längsachse 3 des Kolbens zu liegen kommt. Dabei ist die Lage des Ovals nicht unbedingt an eine exakte Anordnung 90° quer zur Längsachse gebunden. In Anpassung an die Pleuelbewegung und die damit verbundene Ausrichtung der Kräfte kann auch das Oval der Bolzenbohrung entsprechend ange-As can be seen mainly from Figure 2, the holes are designed oval for the piston pin according to the invention, the major axis 2 of the oval being transverse to the longitudinal axis 3 of the piston come to lie. The position of the oval is not necessarily bound to an exact arrangement 90 ° transversely to the longitudinal axis. In adaptation to the connecting rod movement and the associated alignment of the forces, the oval of the bolt hole can also be adjusted accordingly.
