Abstract

The bolt has an electronic storage device (1) in its head (3) or shaft. The data in the electronic storage device can be read out with an electronic reader. The storage device can be written to by an electronic writer. The storage device can be accommodated in an aperture (2) in the head of the bolt and is protected by a mechanical protection arrangement (4) which enables electronic data reading and writing.

Description

Die Erfindung betrifft eine Schraube für eine Schraubverbindung, an deren Qualität vorzugsweise höhere Anforderungen gestellt werden. Derartige Schraubverbindungen werden heute bereits im Kraftwerksbau, in der Luft- und Raumfahrttechnik und zunehmend auch im Automobilbau eingesetzt.The invention relates to a screw for a screw connection, on the Quality preferably higher demands are made. Such Screw connections are already used today in power plant construction, in the air and space technology and increasingly also in automotive engineering.

Es besteht das Bedürfnis, die Eigenschaften der Schraubverbindung, z. B. die Vorspannkraft, mit der die Schraube angezogen wurde, zu dokumentie­ ren.There is a need to improve the properties of the screw connection, e.g. B. document the preload with which the screw was tightened ren.

Aus dem Stand der Technik ist keine Möglichkeit bekannt, um eine derarti­ ge Dokumentation mit einfachen Mitteln durchzuführen.No possibility is known from the prior art for such a to carry out documentation with simple means.

Es ist daher die Aufgabe der Erfindung, das vorstehend genannte Problem zu lösen.It is therefore the object of the invention to solve the above problem to solve.

Die Aufgabe wird mit einer Schraube gemäß Patentanspruch 1 gelöst, wo­ nach im Kopf oder im Schaft der Schraube eine elektronische Speichervor­ richtung angeordnet ist, deren Daten mit einer elektronischen Leseeinrich­ tung auslesbar sind.The object is achieved with a screw according to claim 1, where electronic memory in the head or in the shaft of the screw direction is arranged, the data with an electronic reading device are readable.

Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus der nach­ folgenden Beschreibung der Ausführungsbeispiele in Verbindung mit den beigefügten schematischen Zeichnungen. Further measures and advantages of the invention result from the following description of the embodiments in connection with the attached schematic drawings.  

Fig. 1 zeigt eine erste Ausführungsform der erfindungsgemäßen Schraube. Fig. 1 shows a first embodiment of the screw according to the invention.

Fig. 2 zeigt eine zweite Ausführungsform der erfindungsgemäßen Schraube. Fig. 2 shows a second embodiment of the screw according to the invention.

Fig. 3 zeigt eine dritte Ausführungsform der erfindungsgemäßen Schraube. Fig. 3 shows a third embodiment of the screw according to the invention.

Nach Fig. 1 ist bei der ersten Ausführungsform der erfindungsgemäßen Schraube die Speichervorrichtung 1 in einer wannenförmigen Ausbildung 2 im Schraubenkopf 3 angeordnet und mittels einer Kunststoffschicht 4 vor mechanischen Einwirkungen geschützt.According to Fig. 1, the memory device 1 is arranged in a trough-shaped construction 2 in the screw head 3 and protected by a plastic layer 4 from mechanical impact in the first embodiment of the screw according to the invention.

Nach Fig. 2 ist bei der zweiten Ausführungsform der erfindungsgemäßen Schraube die Speichervorrichtung 1 in einer axialen Bohrung 5 im Schrau­ benschaft angeordnet und mittels einer Kunststoffverfüllung 6 vor mecha­ nischen Einwirkungen geschützt, wobei die Lage der Speichervorrichtung I so gewählt wird, daß ihre vorgesehene Funktion erfüllt ist. Bei dieser Aus­ führungsform kann z. B. die Bohrung 5 zur Bestimmung der Vorspannung an einer Schraubverbindung dienen, wobei ihre Länge bzw. die Längenän­ derung mechanisch mittels eines Meßstiftes ermittelt wird. Dieser Meßstift kann an seiner Spitze eine Lese- oder eine Lese/Schreib-Einrichtung auf­ weisen, mit der die Daten ein- oder ausgelesen werden können.According to Fig. 2 of the screw according to the invention, the storage device 1 in an axial bore 5 is located benschaft in Schrau and protected by a plastic filling 6 before mecha African effects in the second embodiment, the position of the memory device I selected so that their intended function fulfills is. In this imple mentation form z. B. the bore 5 to determine the bias on a screw connection, its length or the length change is determined mechanically by means of a measuring pin. This measuring pen can have at its tip a reading or reading / writing device with which the data can be read in or out.

Nach Fig. 3 ist bei der dritten Ausführungsform der erfindungsgemäßen Schraube die Speichervorrichtung 1 in einer Schraube aus Kunststoff oder einem Material mit vergleichbaren, nichtmetallischen elektrischen Eigen­ schaften angeordnet. Da Kunststoff gegenüber Metall nur geringe Abschir­ mungseigenschaften aufweist, kann in diesem Fall die Speichervorrichtung 1 vollständig in das Schraubenmaterial eingebettet sein.According to FIG. 3, the storage device 1 in a screw made of plastic or a material is arranged with comparable non-metallic electrical properties inherent in the third embodiment of the screw according to the invention. Since plastic has only low shielding properties compared to metal, in this case the storage device 1 can be completely embedded in the screw material.
