Abstract
Ein Kurbelgehäuse einer Brennkraftmaschine besteht aus einem Unterteil (1) und einem Oberteil (2), die entlang einer in der Kurbelwellenmitte liegenden Ebene aneinander liegen. Es weist eine der Anzahl der Zylinder (3) entsprechende Anzahl von Kurbelräumen (5,6) auf, die von Querwänden (7,8) begrenzt sind. Die Seitenwände (20,21) des Oberteils sind im Bereich jedes Kurbelraumes (5,6) mit gewichtsreduzierenden Durchbrüchen versehen. In den im Oberteil des Kurbelgehäuses liegenden Teil jedes Kurbelraumes (5,6) ist ein becherförmiges Bauteil eingesetzt, das die Durchbrüche abdeckt. A crankcase of an internal combustion engine consists of a lower part (1) and an upper part (2), which lie against one another along a plane lying in the middle of the crankshaft. It has a number of crank chambers (5,6) corresponding to the number of cylinders (3), which are delimited by transverse walls (7,8). The side walls (20, 21) of the upper part are provided with weight-reducing openings in the area of each crank chamber (5, 6). In the part of each crank chamber (5, 6) located in the upper part of the crankcase, a cup-shaped component is inserted, which covers the openings.
