Title (DE) MEHRLAGIGER INNENSCHLAUCH
(EN) MULTILAYER INNER TUBE
(FR) TUBE INTÉRIEUR MULTICOUCHE
Abstract:
(DE) Offenbart ist ein mehrlagiger Innenschlauch (1) für ein Fahrzeugrad mit einer Innenschicht (2), die mit einer gasförmigen Füllung des Innenschlauchs (1) in Kontakt steht und mit einer von der Innenschicht (2) unterschiedenen Außenschicht (3) aus thermoplastischem Polyurethan, die mit einer äußeren Umgebung des Innenschlauchs (1) in Kontakt steht. Um den Innenschlauch (1) zu verbessern wird vorgeschlagen, dass auch die Innenschicht (2) aus thermoplastischem Polyurethan besteht.
(EN) The invention relates to a multilayer inner tube (1) for a vehicle wheel, comprising an inner layer (2) that is in contact with a gaseous filling of the inner tube (1) and a thermoplastic polyurethane outer layer (3) that is different from the inner layer (2) and that is in contact with an area surrounding the inner tube (1). In order to improve the inner tube (1), the inner layer (2) also consists of a thermoplastic polyurethane.
(FR) L'invention concerne un tube intérieur multicouche (1) pour une roue de véhicule pourvue d'une couche intérieure (2) qui est en contact avec un remplissage gazeux du tube intérieur (1) et d'une couche extérieure (3) différente de la couche intérieure (2) en polyuréthane thermoplastique qui est en contact avec un environnement extérieur du tube intérieur (1). Pour améliorer le tube intérieur (1), il est proposé que la couche intérieure (2) soit également constituée de polyuréthane thermoplastique.
