  Verfahren   zur Herstellung   von Stahlzylindern mit   aufgeschrumpftem Aluminium-   
 EMI1.1 
 



   Den Gegenstand der Erfindung bildet ein Verfahren zur Herstellung von Stahlzylindern mit   aufgeschrumpftem Aluminiunnippenmantel   für Verbrennungskraftmaschinen. das dadurch gekenn- zeichnet ist, dass das Einarbeiten der Kühlrippen in den   Aluminiumvollmantel   erst nach   Aufschn   mpfung desselben auf den Stahlzylinder erfolgt, wodurch dem Auftreten von inneren Spannungen im   Ali'minr'm-   mantel vorgebeugt wird.

   Derartige innere Spannungen, welche letzten Endes zu einem Bruche des
Rippenmantels führen, treten bei den bekannten Verfahren des   Aufschrfmpfens   eines   Alrminirm-   rippenmantels auf einen Stahlzylinder infolge der   ungleichmässigen   Zusammenziehung des Mantels auf. welche durch die unregelmässige Gestalt und Massenverteilung bei einem bereits mit Rippen versehenen Mantel bedingt ist. 



   In der Zeichnung ist ein nach der Erfindung hergestellter Stahlzylinder mit Aluminiumrippenmantel in einem Längsschnitt dargestellt. 



   Auf den mit glatt polierter Aussenfläche hergestellten Stahlzylinder A, dessen Kopf mit einer Kappe C versehen ist, welche die die Ein-und Austrittskanäle   01     02   bildenden Hauben und die Einund Austrittsbohrungen A3 und A4 enthält ; wird ein innen ebenfalls glatt ausgedrehter Aluminiumvollmantel D in bekannter Weise aufgeschrumpft, in welchen sodann die Kühlrippen D'eingearbeitet werden.

  Process for the production of steel cylinders with shrunk-on aluminum
 EMI1.1
 



   The subject matter of the invention is a method for producing steel cylinders with a shrunk-on aluminum lip jacket for internal combustion engines. This is characterized in that the cooling fins are only worked into the solid aluminum jacket after it has been snapped onto the steel cylinder, which prevents internal stresses from occurring in the aluminum jacket.

   Such internal tensions which ultimately lead to a break in the
Lead rib jacket occur in the known methods of shrinking an Alrminirmrippenmantels on a steel cylinder due to the uneven contraction of the jacket. which is caused by the irregular shape and mass distribution in a jacket that is already provided with ribs.



   In the drawing, a steel cylinder made according to the invention with an aluminum rib jacket is shown in a longitudinal section.



   On the steel cylinder A produced with a smoothly polished outer surface, the head of which is provided with a cap C which contains the hoods forming the inlet and outlet channels 01 02 and the inlet and outlet bores A3 and A4; a solid aluminum jacket D, which is also turned smooth on the inside, is shrunk on in a known manner, into which the cooling fins D 'are then worked.
