Fig. 1 und Fig. 2 zeigen einen Abschnitt der Innenseite 2 eines Fahrzeugluftreifens radial innerhalb des nicht gezeigten Laufstreifens. Hier wird die Innenseite 2 üblicher Weise von einer Innenschicht aus Gummi gebildet. Radial innerhalb des Laufstreifens ist über den gesamten Innenumfang ein aus Gummi bestehendes Band 3 bereits mit der Vulkanisation des Reifens eingebunden worden. Das Band 3 ist ein Kompensationsband zur Verbesserung der Reifenrundlaufeigenschaften und ist nicht Gegenstand dieser Erfindung. Über einen kurzen Abschnitt seinerFig. 1 and Fig. 2 show a portion of the inside 2 of a pneumatic vehicle tire radially inside the tread, not shown. Here, the inside 2 is usually formed by an inner layer of rubber. Radially inside the tread, a rubber band 3 has already been integrated over the entire inner circumference with the vulcanization of the tire. The belt 3 is a compensation belt for improving the tire running characteristics and is not the subject of this invention. About a short section of his
Umfangserstreckung ist das Kompensationsband 3 mit der Innenseite 2 des Reifens nicht verbunden worden, sondern es ist an dieser Stelle durch eine in den Zeichnungsfiguren nicht gezeigte Trennfolie, beispielsweise aus Teflon, ein Anhaften des Kompensationsbandes 3 auf der Innenseite 2 verhindert worden. Wie Fig. 2 zeigt, ist in diesem Abschnitt das Kompensationsband 3 verjüngt - seinePeripheral extent, the compensation band 3 has not been connected to the inside 2 of the tire, but it has been prevented at this point by a release film, not shown in the drawing figures, for example made of Teflon, an adhesion of the compensation tape 3 on the inside 2. As shown in FIG. 2, the compensation band 3 is tapered in this section - its
Breite wird an einer Stelle kontinuierlich geringer und abschließend wieder größer - sodass in diesem Abschnitt das Band 3 eine geringere Masse aufweist. Die an dieser Stelle „fehlende" Masse wird durch ein hier befestigtes Elektronikbauteil 1 kompensiert.Width is continuously decreasing at one point and finally increasing again - so that in this section the band 3 has a lower mass. The "missing" mass at this point is compensated by an electronic component 1 fastened here.
Nach der Vulkanisation bzw. der Fertigstellung des Reifens wird die erwähnte Trennfolie entfernt und das Kompensationsband 3 an seiner schmälsten Stelle mit einem Loch 3a versehen. Unter dem Kompensationsband 3 wird das Elektronikbauteil 1 positioniert, eine am Elektronikbauteil 1 angeordnete Hülse 4 greift in das Loch 3a des Bandes 3. Von oben her wird ein Verschluss 5 in die mittige Öffnung der Hülse 4 eingedrückt und das Elektronikbauteil 1 derart fixiert.After the vulcanization or the completion of the tire, the mentioned release film is removed and the compensation band 3 is provided at its narrowest point with a hole 3a.
