Description

Die vorliegende Erfindung betrifft die Verstellung von Excenterringen, die für die Lagerung einer Kurbelwelle eingesetzt werden.The The present invention relates to the adjustment of eccentric rings, the for the bearing of a crankshaft can be used.

Aus der Patentliteratur ( DE 19841381A1 ) ist es bekannt, die Kurbelwelle in Excenterringen zu lagern, um so beim Schwenken dieser, die Kolbenendlagen zu verschieben und so das geometrische Verdichtungsverhältnis im Motorbetrieb den Betriebsverhältnissen anzupassen.From the patent literature ( DE 19841381A1 ) It is known to store the crankshaft in eccentric rings so as to move the piston end positions during pivoting of the latter and thus adjust the geometric compression ratio during engine operation to the operating conditions.

Alle Excenterringe müssen synchron verstellt werden. Dazu wurden diese bisher (z.B. DE 10051271A1 ) aufwendig miteinander verbunden und mittels eines Zahneingriffes und einer Ritzelwelle verstellt. Momente auf der Ritzelwelle sind bei dieser Art der Lösungen immer vorhanden. Es muss also für jede Halteposition Energie aufgebracht werden.All eccentric rings must be adjusted synchronously. These were previously (eg DE 10051271A1 ) consuming interconnected and adjusted by means of a tooth engagement and a pinion shaft. Moments on the pinion shaft are always present in this type of solutions. So it must be applied for each stop position energy.

Der Erfindung liegt nun die Aufgabe zu Grunde, diese Nachteile aus der Welt zu schaffen.Of the Invention is now the object of these disadvantages from the To create the world.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, indem die Excenterringe durch Gestänge mit der Verstellwelle verbunden werden. Dabei ist die Verstellwelle so zu positionieren, dass bei gewünschten Lagen (z.B. Endlagen) der Hebelarm zu Null wird und so keine Verstell-/Haltemomente auf die Verstellwelle wirken. Somit entfällt die Halteenergie für diese Positionen. Für Positionen nahe diesen Lagen, sind die Haltemomente gering, da der Hebelarm relativ klein ist.These Task is according to the invention solved by by connecting the eccentric rings by linkage with the adjusting shaft become. The adjusting shaft should be positioned so that desired Positions (e.g., end positions) the lever arm becomes zero and so no adjustment / retention moments act on the adjusting shaft. This eliminates the holding energy for these Positions. For Positions close to these layers, the holding moments are low because of Lever is relatively small.

Die Erfindung wird anhand schematischer Zeichnungen näher erläutert. Es zeigen:The The invention will be explained in more detail with reference to schematic drawings. It demonstrate:

1: die Lagerstelle der Kurbelwelle in mittlerer Verstellposition 1 : the bearing point of the crankshaft in the middle adjustment position

2: die Lagerstelle der Kurbelwelle in Richtung höherer Verdichtung verstellt 2 : The bearing point of the crankshaft is adjusted in the direction of higher compression

3: die Lagerstelle der Kurbelwelle in Richtung niedriger Verdichtung verstellt 3 : The bearing point of the crankshaft is adjusted in the direction of low compression

Die schematische Darstellung 1 zeigt eine Lagerstelle einer Kurbelwelle (3), welche in einem Excenterring (4) aufgenommen ist und nach unten im Kurbelraum durch den Lagerdeckel (1) begrenzt wird. An dem Excenterring (4) hängt eine Lasche (5) in den Kurbelraum ragend, an welchem die Verstellstange (7) drehbar angelenkt ist. Die Verstellwelle (8) wird an einer passenden Stelle im Kurbelraum positioniert. Die Position ist so zu wählen, dass für die gewünschten Nullmomentenlagen die Wirklinien der Verstellstange (7) mit der der Hebelstange (9) zusammenfallen.The schematic representation 1 shows a bearing point of a crankshaft ( 3 ), which in an eccentric ring ( 4 ) and down in the crankcase through the bearing cap ( 1 ) is limited. At the eccentric ring ( 4 ) hangs a tab ( 5 ) projecting into the crankcase, on which the adjusting rod ( 7 ) is hinged. The adjusting shaft ( 8th ) is positioned at a convenient location in the crankcase. The position should be selected so that the operating lines of the adjustment rod ( 7 ) with the lever rod ( 9 ) coincide.

Die schematischen Darstellungen 2 u. 3 zeigen jeweils die Nullmomentenlagen für die Verstellung. Es ist zu erkennen, dass dafür die Wirklinien der Verstellstange (7) und Hebelstange (9) keinen Hebelarm zu dem Mittelpunkt der Verstellwelle (8) haben und somit diese momentenfrei ist.The schematic representations 2 u. 3 each show the zero moment positions for the adjustment. It can be seen that for this purpose the action lines of the adjustment rod ( 7 ) and lever rod ( 9 ) no lever arm to the center of the adjusting shaft ( 8th ) and thus this torque-free.
