Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von hohlgeschmiedeten und mit einem aufgelöteten Deckel verschlossenen Ventilstößeln aus Stahl nach Patent 823. 40,1. Die vorliegende Zusatzerfinidung betrifft eine weitere Ausgestaltung der im Patent 823 401 gekennzeichneten Erfindung und! besteht darin, daß ein Deckel aus Hartguß aufgelötet und nach dem Löten gehärtet wird.The invention relates to a method for producing hollow forged and valve tappets made of steel according to the patent, closed with a cover soldered on 823. 40.1. The present additional invention relates to a further embodiment the invention identified in patent 823 401 and! is that a lid made of chilled cast iron is soldered and hardened after soldering.

Da der Deckel 'des nach der Erfindung hergestellten Stößels unmittelbar vom Nocken der Stößelwelle beaufschlagt wird, ist es, erforderlich, diesen entsprechend widerstandsfähig zu machen, was durch Auswahl eines geeigneten Werkstoffes sowie durch einen Härtevorgang erfolgt. Um nun der Tatsache Rechnung zu tragen, daß der Nocken der Stößelwelle aus Stahl besteht, findet ein Deckel aus gehärtetem Hartguß Verwendung, der zusammen mit dem Stahlstößel guteLaufeigenschaften aufweist. Der Gegenstand der Erfindung ist in einen Ausführungsbeispiel in der Abbildung dargestellt. Mit i ist eine Stößelhülse bezeichnet, die einen verstärkten und profilierten Boden 2 besitzt. Diese Stößelhülse aus geschmiedetem dünnwandigem Stahl ist mit einem Deckel 3 verschlossen, der auf die Hülse-i aufgelötet ist und der aus Hartguß besteht.Since the cover 'of the plunger manufactured according to the invention directly is acted upon by the cam of the tappet shaft, it is necessary to adjust this accordingly to make resistant what by choosing a suitable material as well takes place through a hardening process. In order to take into account the fact that the The cam of the tappet shaft is made of steel and a cover made of hardened chilled cast iron Use which, together with the steel plunger, has good running properties. Of the The subject of the invention is shown in one embodiment in the figure. With i a plunger sleeve is referred to, which has a reinforced and profiled base 2 owns. This tappet sleeve made of forged thin-walled steel is equipped with a Cover 3 closed, which is soldered onto the sleeve-i and which consists of chilled cast iron.
