Abstract
Description
Die Erfindung betrifft eine Zylinderlaufbahn insbesondere für eine Brennkraftmaschine zum Einsatz in einem Kraftfahrzeug, sowie ein Verfahren zur Herstellung einer solchen Zylinderlaufbahn.The The invention relates to a cylinder bore, in particular for an internal combustion engine for use in a motor vehicle, and a method of manufacture such a cylinder liner.

an dem aus der
Aufgabe der Erfindung ist es demgegenüber, eine Zylinderlaufbahn, welche beim Einsatz zum Beispiel in einer Brennkraftmaschine eines Kraftfahrzeugs eine Reduktion des Ölverbrauchs, eine Reduktion der Emission ölbedingter Schadstoffe wie unverbrannte Kohlenwasserstoffe und Partikel und eine Reduktion des Verschleißes der Laufbahn der Zylinderlaufbuchse ermöglicht, sowie ein Verfahren zur Herstellung einer solchen Zylinderlaufbahn bereitzustellen.task the invention it is in contrast, a Cylinder runway, which when used for example in an internal combustion engine a motor vehicle, a reduction in oil consumption, a reduction the emission of oil Pollutants such as unburned hydrocarbons and particles and a reduction of wear the career of the cylinder liner allows, as well as a method to provide such a cylinder liner.
Diese Aufgabe wird durch eine Zylinderlaufbahn mit den Merkmalen des Anspruchs 1 bzw. ein Verfahren zur Herstellung einer Zylinderlaufbahn mit den Merkmalen des Anspruchs 7 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der jeweiligen Unteransprüche.These The object is achieved by a cylinder liner with the features of the claim 1 and a method for producing a cylinder bore with the Characteristics of claim 7 solved. Advantageous embodiments and further developments of the invention are Subject of the respective subclaims.
Die Zylinderlaufbahn mit einer gehonten Lauffläche in einem Zylinder ist gemäß der Erfindung dadurch gekennzeichnet, dass mehrere Teilbereiche der Lauffläche mit Mikrostrukturen versehen sind.The Cylinder runway with a honed tread in a cylinder is characterized according to the invention characterized in that several subregions of the tread with Microstructures are provided.
Die erfindungsgemäße Zylinderlaufbahn zeichnet sich somit durch eine Aufteilung der Lauffläche in mehrere Bereiche auf, wobei in bestimmten Bereichen vorgesehene Mikrostrukturen mit gehonten Laufflächenbereichen und damit auch deren jeweilige Vorteile kombiniert sind.The inventive cylinder liner draws Thus, by dividing the tread into several areas, with in certain areas envisaged microstructures with honed Tread areas and thus their respective advantages are combined.
In einer bevorzugten Ausgestaltung der Erfindung sind die mit der Mikrostruktur versehenen Teilbereiche um den oberen und den unteren Totpunkt eines in der Zylinderlaufbahn geführten Kolbens angeordnet. Es werden so die vorteilhaften Eigenschaften der Mikrostrukturen in den Bereichen um den oberen und den unteren Totpunkt zur Ausbildung eines stationären Ölfilms in diesen Bereichen und die vorteilhaften Eigenschaften der gehonten Lauffläche im mittleren Bereich zur Erzielung eines möglichst geringen Ölrückhaltevolumens in diesem Bereich kombiniert.In A preferred embodiment of the invention are those with the microstructure provided partial areas around the top and bottom dead center of a guided in the cylinder liner Plunger arranged. It will be the beneficial properties the microstructures in the areas around the top and the bottom Dead center to form a stationary oil film in these areas and the advantageous properties of the honed tread in the middle Area to achieve as much as possible low oil retention volume combined in this area.
In weiterer Ausgestaltung der Erfindung ist ein Bereich zwischen den mit der Mikrostruktur versehenen Teilbereichen mit einer Spiegelhonung versehen.In Another embodiment of the invention is an area between the provided with the microstructure portions with a mirror honing Mistake.
In weiterer Ausgestaltung der Erfindung werden die Mikrostrukturen mittels Laserbearbeitung in die Lauffläche eingebracht.In Another embodiment of the invention, the microstructures introduced by laser processing in the tread.
Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass zunächst die Lauffläche der Zylinderlaufbahn auf ihrer gesamten axialen Länge gehont und dann in den Bereichen um die Totpunkte mit der Mikrostruktur versehen wird.The inventive method is characterized by the fact that first the running surface of the cylinder liner honed over its entire axial length and then in the areas around the dead centers with the microstructure is provided.
Hierbei kann zunächst die gesamte Lauffläche mit einer abschließenden Spiegelhonung bearbeitet werden, woraufhin die Mikrostrukturen in die mehreren Teilbereiche eingebracht werden. Alternativ ist es auch möglich, dass nach der Durchführung einer ersten und gegebenfalls einer zweiten Honstufe der gesamten Lauffläche die Mikrostrukturen in die mehreren Teilbereiche eingebracht werden und anschließend die gesamte Lauffläche einschließlich der Teilbereiche mit den Mikrostrukturen mit einer Spiegelhonung bearbeitet wird.in this connection can first the entire tread with a final Mirror honing are processed, whereupon the microstructures in the several sub-areas are introduced. Alternatively it is also possible, that after performing a first and, if necessary, a second honing step of the entire tread the Microstructures are introduced into the multiple sections and subsequently the entire tread including the subregions with the microstructures with a mirror honing is processed.
