Abstract

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.Cast core (1) for the coolant jacket of a crankcase of an internal combustion engine with cylinders (2, 2 ') arranged in at least one row and with core supports (3, 3 '), the at least one, adjacent to a cylinder head crankcase wall penetrate, the core supports (3, 3 ') of at least two, in one Row of cylinders (2, 2 ') with each other via at least one bridge (4, 4') are connected.

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.

Figure 00000001
The construction described here gives the casting core maximum rigidity during the casting process. As a result, the coolant channels of the coolant jacket can be represented through the narrowest coolant passage openings. In addition, the core rigidity ensures compliance with the tightest dimensional tolerances, which means that time-consuming mechanical processing can be dispensed with.
