Abstract

Verfahren zur Herstellung eines Zylinderkurbelgehäuses (10), bei denen eine Gießform (28) geschlossen wird, mindestens eine Stahlpinole (34) in die Gießform (28) zur Bildung mindestens eines Zylinderraums (14) eingeführt wird, die Gießform (28) mit einer Metallschmelze efüllt wird, die mindestens eine Stahlpinole (34) nach dem Erstarren der Schmelze wieder ausgeschoben wird, daraufhin die Gießform (28) geöffnet und das Zylinderkurbelgehäuse (10) aus der Gießform (28) ausgeworfen wird, woraufhin eine nasse hängende Buchse (16) in jeden durch die eine oder mehreren Stahlpinolen (34) gebildeten Zylinderräume (14) eingesteckt wird, sind bekannt.Method for producing a cylinder crankcase (10), in which a casting mold (28) is closed, at least one steel quill (34) is introduced into the casting mold (28) to form at least one cylinder space (14), the casting mold (28) is molten with a metal is filled, the at least one steel quill (34) is pushed out after the solidification of the melt, then the mold (28) is opened and the cylinder crankcase (10) is ejected from the mold (28), whereupon a wet hanging socket (16) in each of the cylinder spaces (14) formed by the one or more steel quills (34) is inserted are known.

Zur Erzeugung eines Kühlmittelmantels ohne Kerne verwenden zu müssen, wird vorgeschlagen, dass vor dem Einsetzen der Buchsen (16) die den mindestens einen Zylinderraum (14) begrenzenden Seitenwände (36) mechanisch bearbeitet werden, wobei ein erster Abschnitt (38) größeren Durchmessers zwischen einem zweiten axialen Abschnitt (40) kleineren Durchmessers und einem dritten axialen Abschnitt (44) kleineren Durchmessers, die durch die Stahlpinole (34) gebildet werden, erzeugt wird.

Figure imgaf001
In order to produce a coolant jacket without having to use cores, it is proposed that prior to insertion of the bushes (16) the at least one cylinder chamber (14) limiting side walls (36) are machined, with a first portion (38) of larger diameter between a second smaller diameter axial portion (40) and a smaller diameter third axial portion (44) formed by the steel quill (34).
