Abstract
Description
Die Erfindung beschreibt die Lagerung von zwei gleichachsig hintereinander und achsparallel zueinander versetzt angeordneten Wellen.The Invention describes the storage of two equiaxed one behind the other and axially parallel to each other staggered waves.
In einigen Anwendungsfällen ist es erforderlich, dass die Höhenlage einer der Wellen verändert werden muss, während die andere Welle ihre definierte Lage behält. Ein Problem hierbei stellt die Lagerung der beiden Wellen (oder Scheiben) dar.In some applications it is necessary that the altitude one of the waves will be changed must while the other wave retains its defined position. A problem here the storage of the two shafts (or discs) is.
Ein derartiger Anwendungsfall ist beispielsweise bei einer Kolbenkraftmaschine mit veränderbarem Verdichtungsverhältnis gegeben, bei der die Veränderung durch ein Anheben bzw. Ansenken der Kurbelwellenachse gegenüber einer Bezugsebene vorgenommen wird.One Such application is, for example, in a reciprocating internal combustion engine with changeable compression ratio given, at the change by raising or lowering the crankshaft axis relative to a Reference plane is made.

Bei
der Anwendung der verstellbaren Kurbelwellenlagerung
Der Erfindung liegt nun die Aufgabe zugrunde, eine Lagerungsart zu schaffen, die die genannten Nachteile der fliegenden Lagerung, des ölgefüllten Gehäuses und der komplexen Lagerungsaufnahme nicht hat und trotzdem kostengünstig und kompakt gestaltbar ist. Des Weiteren soll der Gesamtbauaufwand reduziert werden, indem auf den Ausgleich zum Steuertrieb verzichtet wird und dieser nun in die Lagerung auf der Getriebeseite integriert wird.Of the Invention is an object of the invention to provide a storage method, the mentioned disadvantages of the flying storage, the oil-filled housing and the complex storage receptacle does not have and still inexpensive and is compact formable. Furthermore, the total construction costs should be reduced be avoided by waiving the compensation for tax incentive and this now integrated into the storage on the transmission side becomes.
Diese Aufgabe wird gemäß der Erfindung gelöst, indem die Lagerung beidseitig ausgeführt wird, so dass blockseitig ein Lagerträger, welches am Block zentriert und verschraubt ist, zum Einsatz kommt und getriebeseitig der Gehäusedeckel die weitere Lagerung aufnimmt. Die beiden Scheiben sind in einem stehenden Gehäuse untergebracht, welches dadurch gebildet wird, dass die Getriebeflanschfläche des Blockes verlängert wird und durch einen Gehäusedeckel verschlossen wird. Damit steht nun im Gehäuse kein Öl, so dass die Scherkräfte und Öldruck auf die Gehäusewände entfallen. Das einlaufende Öl in das stehende Gehäuse führt dazu, dass ein Ölnebel für Schmierung und Kühlung der Kopplungselemente entsteht. Das sich unten im Gehäuse ansammelnde Öl kann zu der Ölwanne zurück fließen. Die so gelagerte und abgedichtete Scheibe wird durch den Gehäusedeckel nach außen geführt. An diese wird nun die Kupplungsplatte mit Zahnkranz angeflanscht.These Task is according to the invention solved, by the storage is carried out on both sides, so that block side a bearing carrier, which is centered and bolted to the block, is used and the transmission side of the housing cover the further storage takes up. The two discs are in one standing housing housed, which is formed by the fact that the transmission flange of the Blockes extended is and through a housing cover is closed. So now there is no oil in the housing, so that the shear forces and oil pressure on the housing walls omitted. The incoming oil in the standing housing leads to an oil mist for lubrication and cooling the coupling elements arises. The oil accumulating in the bottom of the housing may become too the oil pan flow back. The so stored and sealed disc is through the housing cover outward guided. At this is now flanged the clutch plate with sprocket.
Um weitere Vereinfachung zu erreichen, wird auf der Seite des Gehäusedeckel eine Doppellagerung als fliegende Lagerung so ausgeführt, dass die Koppelkräfte nicht oder nur geringfügig außerhalt der Lagerebene liegen. Somit kann die Abtriebsscheibe weiter vereinfacht werden und die blockseitige Lagerung eliminiert werden. Die genutzten Wälzlager werden vorzugsweise in die umgebenden Bauteile integriert, um so den Montageaufwand zu reduzieren.Around To achieve further simplification is on the side of the housing cover a double bearing designed as a flying bearing so that the coupling forces not or only slightly except stop the storage level lie. Thus, the driven pulley can be further simplified be eliminated and the block-side storage. The used roller bearing are preferably integrated into the surrounding components so as to to reduce the assembly work.
Bei der Anwendung an einer Kolbenkraftmaschine muss neben dem getriebeseitigen Ausgleich, auch ein steuertriebseitiger Ausgleich bewerkstelligt werden. Diese führt zu sehr hohem Aufwand und weiterer Komplexität des Steuertriebs. Um diesen Aufwand zu reduzieren und mit nur einem Ausgleichsmechanismus auszukommen, wird der Antrieb des Steuertriebs auf die Getriebeseite verlegt und über einen Ketten- bzw. Zahnriemenrad bewerkstelligt. Dieses Antriebsrad sitzt nun vorzugsweise zwischen den Lagerungen oder auf der dem Getriebe gewandten Seite des Gehäusedeckels. Diese Antriebsart hat weitere Vorteile, wie geringere Drehschwingungen für den Steuertrieb. Von dieser Stelle aus können auch die Nebenaggregate angetrieben werden.at The application to a piston engine must be next to the transmission side Compensation, also a taxpayer compensation be accomplished. This leads to very high expenditure and further complexity of the tax drive. To this Reduce effort and get by with just one compensation mechanism, the drive of the timing gear is moved to the gear unit side and about one Chain or toothed belt accomplished. This drive wheel is seated now preferably between the bearings or on the gear facing side of the housing cover. This drive has other advantages, such as lower torsional vibrations for the timing drive. From this point can also the ancillaries are driven.
