Description
Die Erfindung bezieht sich auf einen Betätigungshebel in Form eines Schlepp-, Schwenk- oder Kipphebels für einen Ventiltrieb einer Brennkraftmaschine, mit einer Nockenkontaktrolle, einer Anlagestelle für zumindest ein Gaswechselventil und einer Lagerstelle zur Abstützung gegenüber einem Zylinderkopf der Brennkraftmaschine, wobei der Betätigungshebel zwei durch einen Steg als Teil eines Unterzuges verbundene Seitenwände aufweist, zwischen denen die auf einem Bolzen gelagerte Nockenkontaktrolle geführt ist, und wobei der Bolzen in am Oberzug offenen Bohrungen der Seitenwände angeordnet ist. The invention relates to an operating lever in the form of a towing, pivoting or rocker arm for a valve train of an internal combustion engine, with a cam contact roller, a contact point for at least one gas exchange valve and a bearing for supporting against a cylinder head of the internal combustion engine, wherein the actuating lever two by a Web has as part of a beam connected side walls, between which is guided on a bolt cam contact roller is guided, and wherein the bolt is arranged in open at the top of the holes bores of the side walls.
Ein derartiger Betätigungshebel ist aus der
Aufgabe der Erfindung ist es, den bekannten Betätigungshebel derart zu verbessern, dass die angesprochenen Nachteile behoben sind. Dies soll mit einfachen kostengünstigen Mitteln erfolgen.The object of the invention is to improve the known operating lever such that the disadvantages mentioned are eliminated. This should be done with simple inexpensive means.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Bolzen spielfrei in den am Oberzug offenen Bohrungen der Seitenwände angeordnet ist. Da es schwierig ist, in der Serie eine spielfreie Lagerung sicherzustellen, wird in Weiterbildung der Erfindung vorgeschlagen, dass der Bolzen mit Übermaß in die Bohrungen eingefügt ist. Er kann auch mittels Verstemmen an den Wangen der offenen Bohrungen spielfrei festgelegt sein. Durch das Übermaß bzw. die Presspassung wird der Betätigungshebel am Oberzug so vorgespannt, dass am Unterzug Druckspannungen entstehen. Bei Aufbringen der Last durch den Nocken auf die Nockenkontaktrolle müssen erst die durch das Vorspannen vorhandenen Druckspannungen am Betätigungshebel überkompensiert werden, bevor Zugspannungen am Unterzug auftreten. Das führt zu einer insgesamt geringeren Zugbeanspruchung des Betätigungshebels, wodurch die Beanspruchbarkeit bzw. Festigkeit des Betätigungshebels erhöht wird.According to the invention the object is achieved in that the bolt is arranged without play in the open at the top of the bores of the side walls. Since it is difficult to ensure a backlash-free storage in the series, it is proposed in development of the invention that the pin is inserted with excess in the holes. It can also be fixed without play by caulking on the cheeks of the open holes. Due to the excess or the press fit, the actuating lever is biased at the top so that compressive stresses occur on the undercarriage. When the load is applied by the cam to the cam contact roller, it is first necessary to overcompensate for the compressive stresses on the actuating lever due to pretensioning before tensile stresses occur on the undercarriage. This leads to an overall lower tensile stress of the actuating lever, whereby the strength or strength of the actuating lever is increased.
