Description
Ventilführung für BrennkraftmaschinenValve guides for internal combustion engines
Die Erfindung betrifft eine Ventilführung für Brennkraftmaschinen mit einer Führungsbohrung, die wenigstens zwei ringartige mit Abstand zueinander angeordnete Führungsabschnitte aufweist. The invention relates to a valve guide for internal combustion engines with a guide bore that has at least two having ring-like spaced guide sections.
Bei einer bekannten Brennkraftmaschine (DE-AS 11 48 812) ist die Ventilführung mit zwei im Abstand zueinander angeordneten Kunststoff-Buchsen ausgestattet. Dieser Ausführung haftet der Nachteil an, daß sie den steigenden Anforderungen hinsichtlich Wärme- und Verschleißresistenz nicht standhält.In a known internal combustion engine (DE-AS 11 48 812) is the valve guide is equipped with two spaced apart plastic sockets. This execution is liable The disadvantage is that it does not withstand the increasing requirements with regard to heat and wear resistance.
Aufgabe der Erfindung ist es, eine Ventilführung für eine Brennkraftmaschine so zu gestalten, daß sie bei günstiger Herstellung verschleißfest ist, gute Gleiteigenschaft besitzt und auch bei wechselnden sowie hohen Temperaturen funktionsfähig bleibt.The object of the invention is to provide a valve guide for a Design the internal combustion engine so that it is cheaper Manufacturing is wear-resistant, has good sliding properties and also with changing and high temperatures remains functional.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere, die Erfindung ausgestaltenden Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is achieved by the characterizing features of claim 1. Further, the invention Design features are contained in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß die Keramik-Führungsabschnitte der Ventilführung verschleißfest und temperaturbeständig sind; auch besitzen sie gute Gleiteigenschaften. Diese Führungsabschnitte können entweder direkt im Zylinderkopf oder aber in metallischen Einsätzen vorgesehen werden. Besteht der metal-The main advantages achieved by the invention are to see that the ceramic guide sections of the valve guide are wear-resistant and temperature-resistant; they also have good sliding properties. These guide sections can either be provided directly in the cylinder head or in metallic inserts. Does the metal
lische Einsatz aus einer Bronzelegierung, so bildet sie in Verbindung mit den Keramik-Führungsabschnitten eine vorteilhafte Zweistoffausfiihrung mit besonders guten Gleiteigenschaften. Die Keramik-Führungsabschnitte können durch Beschichten der Ventilführungsbohrungen, z. B. an deren Endbereiche, gebildet werden.lish insert made of a bronze alloy, it forms in Connection with the ceramic guide sections is an advantageous dual-material design with particularly good sliding properties. The ceramic guide sections can be coated by coating the valve guide bores, for. B. at their end areas, are formed.
Es besteht aber auch die Möglichkeit, Keramik-Buchsen in die Ventilführungsbohrung einzusetzen und diese form- und/oder kraftschlüssig, gegebenenfalls auch stoffschlüssig zu befestigen. But there is also the possibility of inserting ceramic sockets into the valve guide bore and shaping and / or shaping them non-positively, if necessary also to be fastened with a material fit.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt, die nachstehend näher beschrieben sind. EsIn the drawing are exemplary embodiments of the invention which are described in more detail below. It

erfindungsgemäßen Ventilführung, Fig. 2 eine Ansicht entsprechend Fig. 1, Fig. 3 eine Teilansicht der Fig. 1 in größerem Maßstab, Fig. 4 eine Einzelheit X der Fig. 1 in größerem Maßstab.valve guide according to the invention, FIG. 2 a view corresponding to FIG. 1, 3 shows a partial view of FIG. 1 on a larger scale, FIG. 4 shows a detail X of FIG. 1 on a larger scale.
Der Zylinderkopf 1 gemäß Fig. 1 weist einen Kanal auf, der in Richtung eines Brennraums 3 mittels eines nicht gezeigten Ventils geöffnet und geschlossen werden kann. Dieses Ventil wirkt mit mit einem Ventilsitz und einer Ventilführung 5 zusammen.The cylinder head 1 according to FIG. 1 has a channel which is in Direction of a combustion chamber 3 can be opened and closed by means of a valve, not shown. This valve cooperates with a valve seat and a valve guide 5.
Die Ventilführung 5 ist gemäß Fig. 1 direkt im, z.B. aus einer Leichtmetall-Legierung bestehenden, Zylinderkopf 1 vorgesehen, d. h. die Führungsbohrung 6 ist Bestandteil des Zylinderkopfs.The valve guide 5 is shown in Fig. 1 directly in, for example from a Light alloy existing cylinder head 1 is provided, d. H. the guide hole 6 is part of the cylinder head.
Innerhalb der Führungsbohrung 6 sind Führungsabschnitte 7, angebracht, die aus Keramik bestehen und sich vorzugsweise über den Endbereichen 9, 10 der Führungsbohrung 6 benachbarte Zonen A und B erstrecken. Die Führungsabschnitte 7, 8 aus Keramik werden durch Beschichten der Zonen A und B gebildet.Within the guide bore 6, guide sections 7 are attached, which are made of ceramic and are preferably located Adjacent zones A and B extend over the end regions 9, 10 of the guide bore 6. The guide sections 7, 8 from Ceramics are formed by coating zones A and B.

In Fig. 2 ist die Ventilführung 11 durch einen metallischen Einsatz 12, z, B. aus einer Bronzelegierung dargestellt, die in die Bohrung 13 des Zylinderkopfes 14 eingepreßt wird.In Fig. 2, the valve guide 11 is through a metallic Insert 12, shown, for example, made of a bronze alloy, which is pressed into the bore 13 of the cylinder head 14.
Die Führungsabschnitte 15, 16 werden hier durch Buchsen 17, 18 aus Keramik gebildet, die in die Führungsbohrung 19 der Ventilführung 11 eingepresst sind (kraftschlüssige Befestigung) .The guide sections 15, 16 are here by bushings 17, 18 made of ceramic, which are pressed into the guide bore 19 of the valve guide 11 (non-positive fastening) .
Nach Fig. 3 weist die Ventilführung 20 keramische Buchsen 21, 22 auf, die beim Gießen der Ventilführung 20 mit dieser verbunden werden. Hierzu ist zwischen der Buchse 21 und der Führungsbohrung 23 ein ineinandergreifender Abschnitt 24 angebracht, der durch einen ringförmigen Ansatz 25 der Buchse gebildet wird. Der Ansatz 25 ist mit gleichem Abstand zum oberen und zum unteren Ende der Buchse 21 angeordnet. Dagegen ist der Ansatz 26 der Buchse 22 am oberen Ende von dieser angebracht.According to Fig. 3, the valve guide 20 has ceramic bushes 21, 22, which are connected to the valve guide 20 during casting. This is between the socket 21 and the Guide hole 23 an interlocking portion 24 attached, which is formed by an annular projection 25 of the socket. The approach 25 is equidistant to arranged at the top and at the bottom of the bushing 21. In contrast, the approach 26 of the socket 22 is at the upper end of this appropriate.
Ist die Ventilführung direkt dem Zylinderkopf 1 zugeordnet, so kann die vorstehende Verankerungsmaßnahme der Buchse 21 und 22 analog angewandt werden.If the valve guide is assigned directly to cylinder head 1, so the above anchoring measure of the bushes 21 and 22 can be applied analogously.
In Fig. 4 weist die Buchse 26 an ihrer äußeren Mantelfläche eine Ausnehmung 28 auf, in die ein korrespondierender Abschnitt 29 des Einsatzes 30 eingerollt ist.In Fig. 4, the socket 26 has on its outer jacket surface a recess 28 into which a corresponding section 29 of the insert 30 is rolled.
