Abstract

Die Erfindung betrifft eine Einrichtung zum Verlagern des Zylinderblocks und -kopfs gegenüber dem Kurbelgehäuse mit den im Oberbegriff des Patentanspruches 1 genannten Merkmalen.The invention relates to a device for moving the cylinder block and head compared to the crankcase with those mentioned in the preamble of claim 1 Features.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Einrichtung zum Verlagern des Zylinderblocks und -kopfs gegenüber dem Kurbelgehäuse mit einer stabilen Lagerung des Stellmechanismus zu gestalten, ohne dass eine übermäßige Gewichtszunahme in Kauf genommen werden müsste.The invention has for its object a generic device for Relocate the cylinder block and head against the crankcase with one stable positioning of the adjusting mechanism to be designed without excessive Weight gain would have to be accepted.

Erfindungsgemäß wird durch die Anordnung und Lagerung der Stellwellen mit ihren Exzentern im oberen, dem Zylinderkopf nahen Bereich des Zylinderblocks und die Anordnung der Lagergassen der Stellwellen im Kurbelgehäuse oberhalb von hohlträgerartig ausgebildeten Tragleisten eine stabile Lagerung des Verstellmechanismus zum Verlagern des Zylinderblocks und -kopfs gegenüber dem Kurbelgehäuse erzielt. Durch die Gestaltung der hohlträgerartigen Tragleisten im oberen Teil des Kurbelgehäuses wird die Stabilität der Kurbelgehäusestruktur wesentlich erhöht, so dass die vom Zylinderblock ausgehenden Kräfte vom Kurbelgehäuse problemlos aufgenommen und weitergeleitet werden können. Dabei ist der Verstellmechanismus so angeordnet, dass die Verbindungsgerade der Lageraugen oder -arme des Zylinderblocks etwa senkrecht zur Zylinderachse steht, wodurch ein Getriebeparallelogramm zur Verlagerung des Zylinderblocks gegenüber dem feststehenden Kurbelgehäuse entsteht.

Figure 00000001
According to the invention, the arrangement and mounting of the actuating shafts with their eccentrics in the upper region of the cylinder block near the cylinder head and the arrangement of the bearing lanes of the actuating shafts in the crankcase above hollow carrier-shaped support strips means that the adjustment mechanism for displacing the cylinder block and head relative to the crankcase is stable achieved. The stability of the crankcase structure is significantly increased by the design of the hollow support-like support strips in the upper part of the crankcase, so that the forces emanating from the cylinder block can be easily absorbed and transmitted by the crankcase. The adjustment mechanism is arranged in such a way that the connecting straight line of the bearing eyes or arms of the cylinder block is approximately perpendicular to the cylinder axis, resulting in a gearbox parallelogram for displacing the cylinder block relative to the fixed crankcase.
