Abstract
Description
Die Erfindung betrifft ein Niet sowie Verfahren zum Verbinden wenigstens zweier Bauteile mittels Niet nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a rivet and method for connecting at least two components by means of rivet according to the preamble of patent claim 1.
Aus
Da der Bolzen ausschließlich Spreizkräfte innerhalb des Hülsenschafts zu erzeugen vermag, ist eine feste, flüssigkeitsdichte Nietverbindung im Bereich des Setzkopfes nicht sichergestellt. Überdies ist die Verwendung der vorgestellten Nietverbindung unter anderem infolge des dauerhaften Verbleibens des Bolzens im Hülsenschaft auf wenige Verwendungsfälle beschränkt.There the bolt exclusively spreading forces inside the sleeve shaft is able to produce, is a solid, liquid-tight riveted joint not ensured in the area of the setting head. Moreover, the use is the presented rivet connection among other things as a result of permanent Remaining of the bolt in the sleeve shaft on a few use cases limited.
Daher ist es die Aufgabe der vorliegenden Erfindung, einen Niet der angegebenen Art sowie ein Verfahren zum Verbinden wenigstens zweier Bauteile mittels des angegebenen Niets vorzuschlagen, welches die vorgenannten Nachteile nicht auf weist.Therefore It is the object of the present invention, a rivet of the specified Art and a method for connecting at least two components to propose by means of the specified rivet, which is the aforementioned Disadvantages not on points.
Diese Aufgabe wird erfindungsgemäß für einen Niet der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.These Task is according to the invention for a Rivet of the type specified with the characterizing features of the claim 1 solved.
Weitere Merkmale und Vorteile der Erfindung gehen im Folgenden aus der Beschreibung eines Ausführungsbeispiels anhand mehrerer Zeichnungen hervor.Further Features and advantages of the invention will become apparent from the description an embodiment based on several drawings.
