Der Erfindung liegt die allgemeine Aufgabe zugrunde, gegenüber dem bekannten Stand der Technik eine weitere Optimierung des Ölverbrauchs durch gezielte Modifizierung des Ölabstreifkolbenrings herbeizuführen, wobei gleichzeitig keine Beschädigung von Gegenlaufflächen, nämlich Zylinderlaufflächen, herbeigeführt werden soll.The invention is based on the general object to bring about a further optimization of the oil consumption by targeted modification of the Ölabstreifkolbenrings compared to the known prior art, at the same time no damage to mating surfaces, namely cylinder surfaces, is to be brought about.
Diese Aufgabe wird gelöst durch einen Ölabstreifkolbenring mit einer durch drei Stege gebildeten radial äußeren Lauffläche, einer radial inneren Umfangsfläche sowie dazwischen angeordneten oberen und unteren Flankenflächen, wobei der einem Brennraum zugewandte erste Steg im montierten Zustand des Kolbenrings an einer ihn umgebenden Gegenlauffläche anliegt, während die beiden axial darunter angeordneten Stege mit vorgebbarem radialen Versatz gegenüber dem ersten Steg zurückgesetzt sind, und wobei die Abstreifbereiche aller Stege im Wesentlichen auf einer Linie, einen definierten Winkel zur Gegenlauffläche bildend, vorgesehen sind Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den zugehörigen Unteransprüchen zu entnehmen.This object is achieved by a Ölabstreifkolbenring with a formed by three webs radially outer raceway, a radially inner peripheral surface and disposed therebetween upper and lower flank surfaces, the combustion chamber facing a first web rests in the mounted state of the piston ring to a mating surface surrounding him, while the two axially disposed below webs are set with predeterminable radial offset relative to the first web, and wherein the stripping of all webs substantially on a line, forming a defined angle to the mating surface, are provided Advantageous developments of the subject invention can be found in the accompanying subclaims.
Mit dem Erfindungsgegenstand wird einerseits eine Optimierung der Hydrodynamik herbeigeführt, die letztendlich zu einer Reduzierung des Ölverbrauchs beiträgt.With the subject invention, on the one hand, an optimization of the hydrodynamics is brought about, which ultimately contributes to a reduction in oil consumption.
Darüber hinaus kann durch Verringerung der Flächenpressung der Verschleiß der Zylinderlaufflächen reduziert werden.In addition, by reducing the surface pressure of the wear of the cylinder surfaces can be reduced.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist der erste Steg gegenüber der Gegenlauffläche einen unter einem vorgebbaren Winkel verlaufenden Abstreifbereich auf, wobei die dem Brennraum zunächst gelegene Abstreifkante scharfkantig ausgebildet ist und der Abstreifbereich sich von dieser Abstreifkante radial nach innen verjüngt.According to an advantageous embodiment of the invention, the first web relative to the mating surface on a running at a predetermined angle stripping, wherein the combustion chamber initially located scraper edge is sharp-edged and the stripping from this scraper edge tapers radially inwardly.
In Analogie zum Stand der Technik gemäß
Gleiches gilt für den letzten Steg.The same applies to the last bridge.
Einem weiteren Gedanken der Erfindung gemäß sind die Abstreifbereiche, insbesondere deren radiale Versätze, so ausgebildet, dass, bezogen auf die Zylinderlauffläche, die Abstreifbereiche auf einer Linie, einen definierten Winkel zur Zylinderlauffläche bildend, vorgesehen sind.According to a further aspect of the invention, the stripping regions, in particular their radial offsets, are designed so that, relative to the cylinder surface, the stripping regions are provided on a line forming a defined angle to the cylinder surface.
Je nach Einsatzfall kann es sinnvoll sein, zumindest die Abstreifkanten der Abstreifbereiche der einzelnen Stege mit einer verschleißfesten Beschichtung zu versehen.Depending on the application, it may be useful to provide at least the scraping edges of the stripping of the individual webs with a wear-resistant coating.
Der Erfindungsgegenstand ist anhand eines Ausführungsbespiels in der Zeichnung dargestellt.The subject invention is illustrated with reference to an exemplary embodiment in the drawing.
