Description
Zylinder und Kurbelkasten aus Aluminium oder Aluminiumlegierung für Verbrennungskraftmaschinen. Die Erfindung betrifft eine Verbrenntungskraft'maschine, insbesondere für Kraftfahrzeuge und Flugzeuge, bei denen es auf Leichtigkeit der Ausführung und beste Ausnutzung des Baustoffes ankommt.Cylinder and crankcase made of aluminum or aluminum alloy for Internal combustion engines. The invention relates to an internal combustion engine, especially for motor vehicles and aircraft where there is a need for lightness Execution and best utilization of the building material matter.
Derartige Antriebsmaschinen wurden bisher in der Weise hergestellt, daß der Kolben oder Kolbenteil aus Aluminium oder Grauguß oder Stahl gefertigt wurde. Außerdem war es üblich, den Kurbelkasten aus Aluminium oder Aluminiummischungen und auch den Zylinder aus Aluminium herzustellen, wobei jedoch im letzteren Falle die Zylinderlaufflächen stets aus Stahl oder Grauguß bestanden. Nach der Erfindung ist es möglich, die Zylinder aus Aluminium oder Aluminiumlegierungen allein herzustellen, wenn die Zylinderlaufflächen einer besonderen Behandlung unterworfen werden.Such prime movers have so far been manufactured that the piston or piston part was made of aluminum or gray cast iron or steel. It was also common for the crankcase to be made of aluminum or aluminum mixtures and also to manufacture the cylinder from aluminum, but in the latter case the cylinder sliding surfaces were always made of steel or gray cast iron. According to the invention it is possible to make the cylinders from aluminum or aluminum alloys alone, if the cylinder sliding surfaces are subjected to a special treatment.
Die Vergütung der Oberfläche (Lauffläche) der Zylinder kann auf verschiedene Weise geschehen, beispielsweise durch Hindurchziehen von Dornen aller Art oder durch Hämmein. Auch kann eine Veredlung des Aluminiums vorgenommen werden durch Vergütung der Laufflächen allein, durch Härten oder Einsetzen. Im Rahmen der Erfindung liegt auch die Anwendung dieser Behandlungen bei dem Aluminiumbaustoff.The remuneration of the surface (running surface) of the cylinder can be different Wise done, for example by pulling thorns of all kinds or through Hammein. The aluminum can also be refined by means of compensation the running surfaces alone, by hardening or setting. Is within the scope of the invention also the application of these treatments to the aluminum building material.
Die Erfindung bietet den Vorteil, daß das schwerste Stück des Motors aus leichtestem Material gefertigt werden kann. Sie ermöglicht ferner, Zylinder als auch Kurbelgehäuse in einem Stück zu gießen, wodurch neben größter Einfachheit der Bearbeitung größte Gewichtsverminderung des fertigen Stückes erreicht wird und bei gleichem toten Gewicht weit größere Zylinderräume, d. h. nicht unerhebliche Leistungssteigerungen erreicht werden können. Durch die Vergütung der Laufflächen wird ferner der schwerwiegende Nachteil jener Maschinen vermieden, bei denen in dem Aluminiumkörper ein Zylinderrohr aus Stahl eingesetzt ist, und bei denen die Wärmeabfuhr verhältnismäßig sehr gering ist, da die abfließende Wärme sowohl die Laufflächen (das Stahlrohr) als auch die Wandung des Zylinderkörpers durchdringen muß, um zum Kühlwasser zu gelangen. Als besonders hinderlich kommt hierbei der nicht zu vermeidende Luftraum zwischen Stahlrohr und Zylinder hinzu, da Luft bekanntlich einen großen Leitungswiderstand bietet, sowie der weitere Umstand, daß Stahl und Aluminium verschiedene Ausdehnungskoeffizienten haben und daher bei Erwärmungen Unzuträglichkeialler Art eintreten müssen. Bei Drehmotoren ergeben schließlich die aus Aluminium hergestellten leichten Zylinder einen über die Gewichtserleichterung hinausgehenden Vorteil insofern, , als die Fliehkräfte vermindert werden.The invention offers the advantage that the heaviest part of the engine can be made of the lightest material. It also enables cylinders as well as the crankcase to be cast in one piece, which in addition to the greatest simplicity machining the greatest weight reduction of the finished piece is achieved and with the same dead weight, much larger cylinder spaces, d. H. not insignificant Performance increases can be achieved. Through the remuneration of the treads it also avoids the serious disadvantage of those machines in which in the aluminum body is a cylinder tube made of steel is used, and where the Heat dissipation is relatively very low, since the dissipating heat both the The running surfaces (the steel tube) and the wall of the cylinder body penetrate must to get to the cooling water. This does not come as a particularly obstacle Air space to be avoided between the steel tube and cylinder is added, since air is known offers a large line resistance, as well as the further fact that steel and Aluminum have different coefficients of expansion and therefore when heated Unfavorable things of all kinds have to occur. In the case of rotary motors, the lightweight cylinder made of aluminum one about the weight reduction additional advantage insofar as the centrifugal forces are reduced.
Gemäß dem Grundgedanken der Erfindung, der Abnutzung unterliegende Teile des Zylinders oder Kurbelkastens aus Aluminium oder Aluminiumlegierung auf mechanischem M'ege oder durch Härten oder Einsetzen zu vergüten, können auch andere Teile des Zylinders und Kurbelkastens dieser Behandlung unterworfen werden. Als solche der Abnutzung unterliegende Teile kommen insbesondere auch in Betracht die Ventilsitze, die Ventilführungen, Lager- und Paßstellen am Zylinder oder Kurbelkasten.According to the basic idea of the invention, subject to wear Parts of the cylinder or crankcase made of aluminum or aluminum alloy Compensation by mechanical means or by hardening or insertion can also be done by others Parts of the cylinder and crankcase of this treatment subject will. As such, parts subject to wear are also included in particular Consider the valve seats, valve guides, bearings and mating points on the cylinder or crankcase.
