Abstract
Description
Die Erfindung betrifft einen Kompressionskolbenring für Kolben von Brennkraftmaschinen oder Verdichtern, mit einer eine Nut aufweisenden Lauffläche einer inneren Umfangsfläche, dazwischen verlaufenden oberen und unteren Flanken sowie einem durch einen Schlitz gebildeten Stoß.The The invention relates to a compression piston ring for pistons of internal combustion engines or compressors, having a groove tread an inner peripheral surface, intervening upper and lower flanks and a through a slot formed bump.
Die
Durch
die
Der
Vielfach werden Kolben von Brennkraftmaschinen mit einer Kolbenringkombination bestückt, die aus einem ersten und zweiten Kompressionsring und einem sogenannten Ölabstreifkolbenring besteht. Maßnahmen, die darauf abzielen, den Ölabstreifeffekt zu verbessern, werden vielfach nur bei Ringen der zweiten oder dritten Nut vorgesehen.frequently become pistons of internal combustion engines with a piston ring combination equipped, the of a first and second compression ring and a so-called oil control piston ring consists. Activities, which aim at the oil scrape effect to improve, are often only in rings of the second or third Groove provided.
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Kompressionskolbenring für Kolben von Brennkraftmaschinen dahingehend weiterzubilden, dass eine verbesserte Kombination mehrerer Funktionen wie reduzierter Ölverbrauch, reduziertes Blowby sowie reduzierte Masse in einem Einzelring, realisiert werden kann, wodurch sich auch reduzierte Bauhöhen und Massen der zum Einsatz gelangenden Kolben und Kurbelgehäuse ergeben.Of the Invention is based on the object, a generic compression piston ring for pistons of internal combustion engines to the effect that an improved Combination of several functions such as reduced oil consumption, reduced blowby as well as reduced mass in a single ring, can be realized resulting in reduced heights and masses of the used Piston and crankcase result.
Diese
Aufgabe wird durch die Kombination folgender Merkmale gelöst:
die
Nut in der Lauffläche
ist im Bereich des Stoßes unterbrochen,
die
Nut ist mit einer in Richtung der oberen Flanke verlaufenden Hinterschneidung
versehen, die Lauffläche
ist mit einer gekrümmten
Kontur versehen und im Bereich der inneren Umfangsfläche ist
eine warmfeste Schlauchfeder angeordnet.This task is solved by the combination of the following features:
the groove in the tread is interrupted in the area of the impact,
the groove is provided with an undercut extending in the direction of the upper flank, the running surface is provided with a curved contour, and a heat-resistant tubular spring is arranged in the region of the inner peripheral surface.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims remove.
Infolge dieser Merkmalskombination wird ein Kombinationskolbenring geschaffen, der die Funktionen eines Kompressionsringes mit denen eines Ölabstreifringes in einem Einzelring realisiert, wobei der dem Brennraum zugekehrte obere Bereich der Lauffläche als Kompressionsteil und der untere Teil der Lauffläche als Ölabstreifteil fungiert.As a result This combination of features creates a combination piston ring, the functions of a compression ring with those of a Ölabstreifringes realized in a single ring, wherein the combustion chamber facing upper area of the tread as a compression part and the lower part of the tread as Ölabstreifteil acts.
Der erfindungsgemäße Kompressionskolbenring kann in Abhängigkeit des Gegenlaufpartners (Zylinder/Zylinderlaufbuchse) mit einer Beschichtung versehen werden, z.B. CKS, Nitrierung, Plasma oder dergleichen.Of the compression piston ring according to the invention can depend on of the counterflow partner (cylinder / cylinder liner) provided with a coating be, e.g. CKS, nitration, plasma or the like.
Durch gezielte Querschnittsstörung im Bereich der inneren Umfangsfläche wird der Kolbenring mit geringstem Twistwinkel ausgelegt.By targeted cross-sectional disturbance in the area of the inner peripheral surface The piston ring is designed with the lowest twist angle.
Die
Querschnittsstörung
kann auch durch eine Kombination der folgenden Merkmale herbeigeführt werden:
axial
versetzte Federnut;
Beschichtung bei erforderlicher Kammerung;
leicht
radial reduzierte Unterflanke;
Innenwinkel.The cross-sectional disturbance can also be brought about by a combination of the following features:
axially offset spring groove;
Coating with required chambering;
slightly radially reduced lower flank;
Interior angles.
Die Hinterschneidung im Bereich der Lauffläche ist vorteilhafterweise größer als 0° und wird – einem weiteren Gedanken der Erfindung gemäß – zwischen 5 und 30°, beispielsweise durch Fräsen, erzeugt.The Undercut in the tread is advantageous greater than 0 ° and will - one further idea of the invention according to - between 5 and 30 °, for example by milling, generated.
Zur Beherrschung der im brennraumseitigen Bereich eingesetzten Schlauchfeder ist selbige warmfest ausgebildet, d.h. sie ist für Temperaturen auch oberhalb von 300°C einsetzbar und erfüllt somit die Warmsetzverluste einer normalen Schlauchfeder.to Control of the hose spring used in the combustion chamber side area the same is formed heat resistant, i. it is also above for temperatures of 300 ° C can be used and fulfilled thus the warm-up losses of a normal hose spring.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und wird wie folgt beschrieben. Es zeigen:Of the Subject of the invention is based on an embodiment in the drawing and is described as follows. Show it:
