Title (EN) PRESSURE SAFEGUARD DEVICE FOR WHEELS FILLED WITH COMPRESSED AIR AND METHOD OF PRODUCTION
(FR) DISPOSITIF DE MAINTIEN DE PRESSION POUR ROUES REMPLIES D’AIR COMPRIMÉ ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(DE) DRUCKSICHERUNGS-VORRICHTUNG FÜR DRUCKLUFT GEFÜLLTE RÄDER UND HERSTELLUNGSVERFAHREN
Abstract:
(EN) A pressure safeguard device (1) for wheels filled with compressed gas comprises at least two annularly closed tubular chambers (2) which are to be arranged in a tyre (4) and extend adjacent to each other along circumferential lines about the tyre axis. The tubular chambers (2) are made from a flexible air-tight flat material and each tubular chamber (2) is formed with a transverse seam (7) and at least one longitudinal seam (8), wherein the at least one longitudinal seam (8) is annularly closed next to the central circumferential line of said tubular chamber (2) and the transverse seam (7) extends about the central circumferential line of said tubular chamber (2). If a tubular chamber (2) is damaged, the other intact tubular chambers (2) expand together over the entire region between the rim (3) and wheel (4) and permit a journey to continue.
(FR) L'invention concerne un dispositif de maintien de pression (1) pour des roues remplies d'air comprimé comprenant au moins deux chambres tubulaires flexibles (2) fermées annulairement devant être disposées dans un pneu (4) et s'étendant le long de lignes circonférentielles autour de l'axe du pneu. Les chambres tubulaires flexibles (2) sont formées d'un matériau plat flexible et étanche à l'air et chaque chambre tubulaire flexibles (2) étant formée avec un joint transversal (7) et au moins un joint longitudinal (8), l'au moins un joint longitudinal (8) étant fermé annulairement le long de la ligne circonférentielle centrale de cette chambre tubulaire (2) et le joint transversal (7) s'étendant autour de la ligne circonférentielle centrale de cette chambre tubulaire (2). Lorsqu'une chambre tubulaire flexible (2) est abîmée, les autres chambres tubulaires flexibles (2) intactes s'étendent ensemble sur l'ensemble de l'espace entre la jante (3) et le pneu (4) et permettent de continuer le déplacement.
(DE) Eine Drucksicherungs-Vorrichtung (1) für Druckgas gefüllte Räder umfasst mindestens zwei in einem Reifen (4) anzuordnende und dabei nebeneinander entlang von Umfangslinien um die Reifenachse verlaufende kreisringförmig geschlossene Schlauchkammern (2). Die Schlauchkammern (2) sind aus einem flexiblen, luftdichten Flachmaterial gebildet und jede Schlauchkammer (2) ist mit einer Quernaht (7) und mindestens einer Längsnaht (8) ausgebildet, wobei die mindestens eine Längsnaht (8) neben der zentralen Umfangslinie dieser Schlauchkammer (2) verlaufend ringförmig geschlossen ist und sich die Quernaht (7) um die zentrale Umfangslinie dieser Schlauchkammer (2) erstreckt. Wenn eine Schlauchkammer (2) verletzt wird, dehnen sich die anderen intakten Schlauchkammern (2) zusammen auf den gesamten Bereich zwischen Felge (3) und Reifen (4) aus und erlauben eine Weiterfahrt.
