Description

Aluminiumzylinder für Brennkraftmaschinen Zusatz zum Patent 677 023 Das Hauptpatent 677 023 betrifft einen Aluminiumzylinder für Brennkraftmaschinen; bei welchen der Aluminiumkolben aus. hartem Metall bestehende federnde Kolbenringe hesitzt, die als Laufringe dienen und deren radiale Breite größer ,als die radiale Tiefe der Ringnuten ist. Zur Verringerung der Verschleißerscheinungen soll nach dem Hauptpatent -die Lauffläche des Zylinders aus :einer siliciumarmen, verhältnismäßig weichen Aluminium-Kupfer-Legierung, z. B. 92 % Aluminium, q. olo Kupfer und weitere bekannte Legierungszusätze; bestehen.Aluminum cylinder for internal combustion engines Addendum to patent 677 023 The main patent 677 023 relates to an aluminum cylinder for internal combustion engines; at which the aluminum piston from. Resilient piston rings made of hard metal, which serve as races and whose radial width is greater than the radial depth of the ring grooves, is seated. To reduce the signs of wear and tear, according to the main patent, the running surface of the cylinder is made of: a low-silicon, relatively soft aluminum-copper alloy, e.g. B. 92% aluminum, q. olo copper and other well-known alloy additives; exist.

Siliciumarme Aluminiumlegierungen sind jedoch schlecht gießbar, so daß ganze Zylinderblöcke von verwickelter Form aus dem Werkstoff des Hauptpatents durch Gießen nur schwierig herstellbar sind. Dagegen lassen sich einfachere Körper, wie Büchsen, Röhren u. dgl., aus siliciumarmer Aluminiumlegierung, dem Zylinderbaustoff des Hauptpatents, auf Zentrifugalgießmaschinen oder durch Pressen oder Ziehen leicht herstellen.However, low-silicon aluminum alloys are difficult to cast, so that whole cylinder blocks of intricate shape from the material of the main patent are difficult to manufacture by casting. On the other hand, simpler bodies can be such as cans, tubes and the like, made of low-silicon aluminum alloy, the cylinder building material of the main patent, on centrifugal casting machines or by pressing or pulling easily produce.

Erfindungsgemäß ist die Anordnung so getroffen, daß eine aus der siliciumarmen, verhältnismäßig weichen Aluminium-Kupfer-Legierung bestehende Laufbüchse in einen aus einer siliciumreichen Aluminium-Silicium-Legierung, z. B. 8 5 % Aluminium, 12 bis 13 0/ö Silicium und weitere bekannte Legierungszusätze, bestehenden Zylinderblock eingesetzt ist. Hierdurch werden die Vorteile der siliciumarmen weichen Aluminium-Kupfer-Legierung als Lauffläche mit denen der leichteren Gießbarkeit des Zylinderblockes in erwünschter Weise vereinigt, und die Formgebung des Zylinderblockes unterliegt keinen Beschränkungen.According to the invention, the arrangement is made so that a liner consisting of the low-silicon, relatively soft aluminum-copper alloy is inserted into a liner made of a silicon-rich aluminum-silicon alloy, e.g. B. 8 5% aluminum, 12 to 1 3 0 / ö silicon and other known alloy additives, existing cylinder block is used. As a result, the advantages of the low-silicon, soft aluminum-copper alloy as a running surface are combined in the desired manner with those of the easier castability of the cylinder block, and the shape of the cylinder block is not subject to any restrictions.
