Abstract

Diese Kurbelwellenlagerbrücke für eine Brennkraftmaschine der Hubkolbenbauart entwickelt, welche Kurbelwellenlagerbrücke an einer Trennebene mit einem Zylinderkurbelgehäuse verbunden ist und äußere mit Abstand zu einer Längsachse einer Kurbelwelle verlaufende Längsträger aufweist, wobei zwischen den Längsträgern quer zur Längsachse ausgerichtete Lagerdeckel für die Kurbelwelle verlaufen, die mit Bohrungshälften von Lagerbohrungen für Kurbelzapfen der Kurbelwelle versehen sind.This crankshaft bearing bridge for an internal combustion engine of Hubkolbenbauart develops which crankshaft bearing bridge is connected to a parting plane with a cylinder crankcase and outer extending at a distance from a longitudinal axis of a crankshaft longitudinal member, extending between the longitudinal beams transversely to the longitudinal axis aligned bearing caps for the crankshaft, with bore halves of Bearing holes for crankshaft crank pins are provided.

Um diese Kurbelwellenlagerbrücke zu optimieren sind die Lagerdeckel der Kurbelwellenlagerbrücke in Richtung Längsachse der Kurbelwelle mit Verbindungselementen abgestützt, die sich zwischen den Längsträgern erstrecken. Darüber hinaus münden die Lagerdeckel zumindest im Bereich der Trennebene unter Vermittlung von Erweiterungen in die Längsträger ein.

Figure imgaf001
In order to optimize this crankshaft bearing bridge, the bearing caps of the crankshaft bearing bridge are supported in the direction of the longitudinal axis of the crankshaft with connecting elements which extend between the longitudinal members. In addition, the bearing caps open at least in the region of the parting plane through the intermediary of extensions in the side members.
