Description
In der Aufhängeöse des Dämpfers wird eine den Tragbolzen aufnehmende
Hülse aus elastischem Material eingesetzt, die unter hoher Vorspannung in ihren
Aufnahmeraum eingedrückt wird. Es entstehen hierdurch starke radiale Kräfte. die
Andererseits besteht bei der Herstellung des Zylinderdekkels mit Aufhãngeöse im Spritzgußverfahren die Möglichkeit, daß sich im Spritzguß kleinste Lunkerbildungen ergeben, so daß es sich insbesondere bei übergroßen und sehr hoch belastetenDSmpfern empfiehlt, Sicherungen zum Ausgleich der vorgenannten Spannungskräfte vorzunehmen.On the other hand, there is a suspension eye in the manufacture of the cylinder cover In the injection molding process there is the possibility that the smallest cavities are formed in the injection molding process result, so that it is particularly the case with oversized and very heavily loaded DSmpfern recommends using fuses to compensate for the aforementioned tension forces.
Neuerungsgemäß wird dies dadurch erreicht, daß eine vor dem Spritzgießen auf dem Zylinderrohr angebrachte Armierung der Aufhängeose mit eingegossen wird.According to the innovation, this is achieved in that a prior to injection molding The reinforcement of the suspension eyelet attached to the cylinder tube is also cast in.
Dadurch wird ohne wesentliche Verteuerung erreicht, daß die auftretenden radialen und Zug- bzw. Druckspannungen durch die Armierung kompensiert werden. Die durch die Armierung entstehende Verteuerung hält sich wesentlich unter den Kosten anderer Verbindungsarten, z.B. des Verschraubens und Verschweißens, wobei Abdichtungsprobleme ebenfalls fehlen.This ensures that the occurring radial and tensile or compressive stresses the reinforcement compensates will. The increase in price caused by the reinforcement is significantly lower the costs of other types of connection, e.g. screwing and welding, whereby Sealing problems are also absent.
Die Armierung besteht nach der Neuerung aus einem CVerstärkungsbleoh mit je drei durch Einschnitte an beiden Enden sich ergebenden Lappen, von denen die beiden äußeren sich zu überlappender der späteren Aufhängeöse entsprechender Ringform gebogen sind, während die inneren Endlappen unter Angleichung an die Rundung des Zylinderrohres nur bis zur Befestigungsstellung an diesem abgebogen sind.According to the innovation, the reinforcement consists of a C reinforcement bleoh with three lobes resulting from incisions at both ends, of which the two outer ones, which are to be overlapped, correspond to the later hanging loop Ring shape are curved, while the inner end lobes conforming to the rounding of the cylinder tube are only bent up to the fastening position on this.
Es können auch umgekehrt die inneren Endlappen zur Ringform umgebogen
werden und die äußeren zur Befestigung am Zylinderrohr dienen.
Um eine innige Verbindung des Spritzgusses mit der Armierung sicherzustellen
sieht die Neuerung weiter vor. daß im Verstärkungsblech Ausnehmungen angeordnet
sind, in die der Spritzguß einlaufen kann.
