Abstract

Gußteil in Form eines Zylinderkurbelgehäuses (11) oder eines Zylinderrohrteils mit einer oder mehreren Zylinderbohrungen (12) und einem Kühlmittelmantelraum (18), der die Zylinderbohrungen (12) im wesentlichen konzentrisch umgibt und von einer Zylinderrohrwandung (14,15) und einer Kühlmittelmantelwandung (16) gebildet wird und an einer Deckfläche (19) (Zylinderkopfsitzfläche) zumindest teilweise abgeschlossen ist, wobei der Kühlmittelmantelraum (18) von gegossenen Wandungsflächen der Zylinderrohrwandung (14,15) und der Kühlmittelmantelwandung (16) gebildet wird, die von der Deckfläche (19) (Zylinderkopfsitzfläche) betrachtet hinterschnittfrei sind, und wobei Brückenelemente (23) in den Kühlmittelmantelraum (18) eingebracht sind, die entweder die Zylinderrohrwandung (14,15) und die Kühlmittelmantelwandung (16) bereichsweise miteinander verbinden und Kühlmittelübertrittsöffnungen (26-42) freilassen oder die Zylinderrohrwandung (14,15) und die Kühlmittelmantelwandung (16) umlaufend miteinander verbinden und den Kühlmittelmantel an der Deckfläche (19) (Zylinderkopfsitzfläche) vollständig abschließen.

Figure 00000001
Cast part in the form of a cylinder crankcase (11) or a cylinder tube part with one or more cylinder bores (12) and a coolant jacket space (18) which essentially concentrically surrounds the cylinder bores (12) and a cylinder tube wall (14, 15) and a coolant jacket wall (16 ) is formed and is at least partially closed off on a top surface (19) (cylinder head seat surface), the coolant jacket space (18) being formed by cast wall surfaces of the cylinder tube wall (14, 15) and the coolant jacket wall (16) formed by the top surface (19) (Cylinder head seat surface) are undercut-free, and wherein bridge elements (23) are introduced into the coolant jacket space (18), which either connect the cylinder tube wall (14, 15) and the coolant jacket wall (16) to one another in regions and leave coolant transfer openings (26-42) open or the Cylinder tube wall (14, 15) and the coolant jacket wall (16 ) Connect all around and completely close off the coolant jacket on the top surface (19) (cylinder head seat surface).
