Abstract (en)

The casting core (1) comprises six cylinders (2,2') which form two cylinder rows (10,10') in a V-arrangement. The core supports (3,3') are formed on the ring channels (9,9') of each cylinder row, and are connected to each other by a bridge (4,4'). An axial core support (5) is formed on the main channel between the cylinder rows. The bridge is located outside the crankcase.

Abstract (de)

Gusskern (1) für den Kühlmittelmantel eines Kurbelgehäuses einer Brennkraftmaschine mit in zumindest einer Reihe angeordneten Zylindern (2, 2') und mit Kernstützen (3, 3'), die zumindest eine, einem Zylinderkopf benachbarte Kurbelgehäusewand durchdringen, wobei die Kernstützen (3, 3') von zumindest zwei, in einer Reihe liegenden Zylindern (2, 2') über zumindest eine Brücke (4, 4') miteinander verbunden sind. Durch die hier beschriebene Konstruktion erhält der Gusskern höchste Steifigkeit beim Gießvorgang. Dadurch sind die Kühlmittelkanäle des Kühlmittelmantels durch engste Kühlmitteldurchtrittsöffnungen darstellbar. Darüberhinaus gewährleistet die Kernsteifigkeit die Einhaltung engster Maßtoleranzen, wodurch aufwendige nachträgliche mechanische Bearbeitung entfallen kann. <IMAGE>
