Description
Ventilverstellung für Brennkraftmaschinen (Zusatzanmeldung zu P 23 35 695.8)Valve adjustment for internal combustion engines (additional registration to P 23 35 695.8)
Die Erfindung betrifft eine Ventilverstellung für Brennkraftmaschinen, bestehend aus einer Antriebswelle, einer Einrichtung zur Umwandlung der Drehbewegung in eine das Ventil betätigende Auf- und Abwärtsbewegung und einer Einrichtung zur Veränderung der Ventilerhebung in Abhängigkeit von der Drehzahl und der Belastung der Brennkraftmaschine, wobei die Antriebswelle als Kurbelwelle ausgebildet ist, die eine angelenkte Kurbelstange zwischen einer ortsfesten Stützwand und einem, in einem spitzen Winkel zu dieser zulaufenden, schwenkbar gelagerten, keilförmigen Verstellglied hin-und herbewegt, wodurch das Verstellglied infolge der Keilwirkung eine Auf- und Abwärtsbewegung ausführt und diese auf das Ventil überträgt, und durch Verschieben des Verstellgliedes der Hub und der Öffnungswinkel des Ventile verändert wird, ohne daß sich im Steuerungsdiagramm die Lage der Symmetrieachse für die Auf- und Abwärtsbewegung mitverändert, nach(Patentanmeldung P 23 35 695.8).The invention relates to a valve adjustment for internal combustion engines, consisting of a drive shaft, a Device for converting the rotary movement into an upward and downward movement that actuates the valve and a device for changing the valve lift as a function of the speed and the load on the internal combustion engine, the drive shaft being designed as a crankshaft with a hinged connecting rod between a stationary support wall and a pivotable, wedge-shaped wall that tapers at an acute angle to this Adjusting member moved back and forth, as a result of which the adjusting member executes an upward and downward movement as a result of the wedge effect and transmits this to the valve, and by moving the adjusting member, the stroke and the opening angle of the valve is changed without changing in the control diagram the position of the axis of symmetry for the upward and downward movement also changed, according to (patent application P 23 35 695.8).
Aufgabe der Erfindung ist es, die Ventilvereteilung nach dem Hauptpatent so zu verbessern, daß diese leicht montiert und billig hergestellt werden kann. Außerdem sollen die Teile keinem nennenswerten Verschleiß unterliegen.The object of the invention is to improve the valve distribution according to the main patent so that it is easy to assemble and can be manufactured cheaply. In addition, the parts should not be subject to any significant wear.

Diese Aufgabe wird erfindungsgemäß dadurch gelößt, daß .die Kurbelstange bei der Hin- und Herbewegung sich einerseits mit einem segmentartig geformten Teil gegen die ortsfeste Stützwand abstützt. Dies bringt den Vorteil, daß die Rolle frei auf der Kurvenbahn dea Verstellgliedes abrollen kann« This object is achieved according gelößt in that .the crank rod on the one hand is supported in the back and forth movement with a segment-shaped part against the fixed bulkhead. This has the advantage that the roller can roll freely on the cam track of the adjusting member «
In weitere Ausgestaltung der Erfindung kann das an einem Ende .kugelförmig ausgebildete und in einem Kolben gelagerte Verstellglied durch eine Feder gegen einen Exzenterbolzen gehalten werden und eine verstellbare Ventilkappe in den Schlitz eingreifen und das Verstellglied fuhren.In a further embodiment of the invention, the adjusting member, which is spherical at one end and mounted in a piston, can be held by a spring against an eccentric pin and an adjustable valve cap can engage in the slot and guide the adjusting member.
Ferner kann der Exzenterhol ssen eine zylindrische Exzenterfläche aufweisen und die wirksame Arbeitefläche des Exzenterbolzens kann innerhalb der Außenkonturen der Lagerzapfen liegen.Furthermore, the Exzenterhol ssen a cylindrical eccentric surface have and the effective working surface of the eccentric bolt can be within the outer contours of the bearing pin lie.
Die Erfindung ist anhand eines in der Zeichnung dargestellten AusfUhrungsbeispieles näher erläutert ι die Figur zeigt eine Querschnitt-Ansicht der erfindungsgemäßen Ventilverstellung. The invention is explained in more detail using an exemplary embodiment shown in the drawing ι the figure shows a cross-sectional view of the valve adjustment according to the invention.

Feder 12 hält das Verstellglied 9 mit dem Kolben 11 gegen einen Exzenterbolzen 13. In einem Schlitz 1U des Verstellgliedes 9 ist eine Rolle 15 vorgesehen, welche auf eine verstellbare Ventilkappe 16 einwirkt, die ihrerseits in den Schlitz 14 eingreift und das Verstellglied 9 führt. Die Verstellkappe 16 ist mit dem Ventil 17 verbunden.Spring 12 holds the adjusting member 9 with the piston 11 against an eccentric pin 13. In a slot 1U of the adjusting member 9, a roller 15 is provided, which on a adjustable valve cap 16 acts, which in turn engages in the slot 14 and guides the adjusting member 9. The adjustment cap 16 is connected to the valve 17.
Der Exzenterbolzen 13 weist eine zylindrische Exzenterfläche 18 auf, dessen wirksame Arbeitsfläche innerhalb der Außenkonturen 19 der Lagerzapfen 20 liegt. Je nach Einsteuerung des Verstellgliedes 9 durch Verdrehen des Exzenterbolzen 13 und Verschieben des Kolbens 11, wird der Hub und der Öffnungswinkel des Ventils 17 verändert.The eccentric bolt 13 has a cylindrical eccentric surface 18, the effective working surface within the outer contours 19 of the bearing pin 20 is located. Depending on the control of the adjusting member 9 by turning the Eccentric bolt 13 and moving the piston 11, the stroke and the opening angle of the valve 17 is changed.
