Abstract
Description
Die Erfindung betrifft aufblasbare Luftreifen oder Luftschläuche für Fahrzeuge. The invention relates to inflatable pneumatic tires or inner tubes for vehicles.
Derartige Luftreifen oder Luftschläuche kommen beispielsweise bei Fahrrädern, Mopeds, Motorrädern, aber auch bei Kraftfahrzeugen zum Einsatz. Aufblasbare Luftreifen oder Luftschläuche bestehen meist aus einer Gummimischung, in die Verstärkungseinlagen integriert sein können. Such pneumatic tires or inner tubes come for example from bicycles, Mopeds, motorcycles, but also used in motor vehicles. inflatable Pneumatic tires or inner tubes are usually made of a rubber mixture into which Reinforcing inserts can be integrated.
Nachteiligerweise kann ein solcher Luftreifen bzw. Luftschlauch leicht durch scharfe Gegenstände beschädigt werden, sodass unerwünschterweise Gas aus dem Luftreifen bzw. Luftschlauch entweichen kann. Beispielsweise kann der Luftschlauch eines Fahrrads beim Überfahren einer Glasscherbe örtlich aufgeschnitten werden, sodass der Luftschlauch sein Gas verliert. Disadvantageously, such a pneumatic tire or air tube can easily be damaged by sharp Objects are damaged, so that gas from the Pneumatic tire or air hose can escape. For example, the Air tube of a bicycle locally when driving over a broken glass be cut open so that the air hose loses its gas.
Aufgabe der Erfindung ist es, einen Luftreifen bzw. Luftschlauch zu schaffen, der nach einer Beschädigung sich selber - zumindest teilweise - repariert. The object of the invention is to provide a pneumatic tire or inner tube which after damage itself - at least partially - repaired.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. This object is achieved by the features of patent claim 1.
Erfindungsgemäß besteht ein Luftreifen bzw. Luftschlauch dazu zumindest teilweise aus einem selbstheilenden Kunststoff oder Gummi. Einen derartigen Kunststoff, der sich selbst repariert, wurde beispielsweise von Wissenschaftlern der Illinois State University entwickelt. Das Prinzip besteht darin, dass in den Kunststoff mikroskopisch kleine Kapseln eingebettet sind, die teilweise Rohstoff für den Kunststoff und teilweise Katalysatoren enthalten. Reißt das Material an einer Stelle, brechen dort die Kapseln auf: Der Rohstoff für den Kunststoff verbindet sich durch den Katalysator mit dem umgebenden Kunststoff und schließt den Riss selbstständig. Die gekitteten Risse haben 75% der Stabilität des Ursprungsmaterials. Dieses Material ist auch in der Ausgabe 04/2001 der Zeitschrift "Trendletter" beschrieben, die vom VNR Verlag für die Deutsche Wirtschaft AG, Bonn, Deutschland, herausgegeben wird. Gummimischungen und sonstige Elastomere fallen hier unter den Oberbegriff Kunststoff. According to the invention, there is a pneumatic tire or air tube, at least in part made of a self-healing plastic or rubber. Such a plastic that repaired itself, for example, by scientists from Illinois State University developed. The principle is that in the plastic microscopic capsules are embedded, some of which are raw material for the Contain plastic and some catalysts. If the material tears in one place break open the capsules there: The raw material for the plastic connects through the catalyst with the surrounding plastic and closes the crack independently. The cemented cracks have 75% of the stability of the Original material. This material is also in the 04/2001 edition of the Magazine "Trendletter" described by the VNR publishing house for the German Wirtschaft AG, Bonn, Germany. Rubber compounds and other elastomers fall under the generic term plastic.
Die Kapseln können bei Luftreifen bzw. Luftschläuchen aus Gummi alternativ auch nur ein Vulkanisationsmittel enthalten, das wie beim Flicken eines Fahrradschlauchs den Gummi an den damit benetzten Stellen vorübergehend anlöst, sodass in diesen Bereichen der Gummi anschließend neu vulkanisiert. Bei dieser erneuten Vulkanisation können beschädigte Stellen, wie Risse, repariert bzw. geschlossen werden. Auch der Einsatz von speziellen Klebstoffen in derartigen Kapseln ist gut denkbar. Alternatively, the capsules can also be used for pneumatic tires or rubber inner tubes contain only one vulcanizing agent, which is like patching one Bicycle tube temporarily loosens the rubber at the areas wetted with it, so that the rubber is then re-vulcanized in these areas. At this renewed vulcanization can repair damaged areas such as cracks or getting closed. The use of special adhesives in such Capsules are conceivable.
Fährt nun beispielsweise ein Fahrradfahrer mit seinem Fahrrad über eine Glasscherbe, sodass der Fahrradschlauch beschädigt wird, muss er nur sicherstellen, dass die Glasscherbe nicht mehr im Fahrradschlauch steckt. Durch die Elastizität geht das Material des Fahrradschlauchs an der beschädigten Stelle dann annähernd wieder in seine Ausgangslage zurück, sodass nur ein Riss bzw. ein Schnitt übrigbleibt. Der Fahrradfahrer muss so nur eine bestimmte Zeit, wie zum Beispiel ein paar Minuten, warten, bis die beschädigte Stelle des Fahrradschlauchs sich selbständig wieder repariert hat. Danach kann er den Fahrradschlauch wieder normal aufpumpen und weiterfahren. Es muss weder das entsprechende Rad am Fahrrad ausgebaut werden, noch muss mühsam der Fahrradschlauch von Hand geflickt oder ausgetauscht werden. For example, a cyclist is now riding his bike over one Broken glass, so that the bicycle tube is damaged, it only has to ensure that the broken glass is no longer in the bicycle tube. Due to the elasticity then the material of the bicycle tube goes to the damaged place almost back to its starting position, so that only one crack or one Cut remains. The cyclist only needs a certain amount of time Example a few minutes, wait for the damaged area of the bicycle tube has repaired itself independently. Then he can use the bicycle tube again Inflate normally and continue. It does not have to be the corresponding bike Bicycle must be removed, the bicycle tube must still be laboriously by hand to be patched or exchanged.
Dieses selbstheilende Material ist natürlich auch für schlauchlose Luftreifen geeignet, wie sie üblicherweise bei Kraftfahrzeugen zum Einsatz kommen. This self-healing material is of course also for tubeless pneumatic tires suitable, as they are usually used in motor vehicles.
Vorteilhafterweise ist bei Reifen, die aus einem Luftschlauch bestehen, der von einem separaten Mantel umgeben ist, der die eigentliche Lauffläche des Reifens bildet, sowohl der Luftschlauch als auch der umgebende Mantel aus dem selbstheilenden Material hergestellt. Wenn nur der Luftschlauch aus dem Material bestünde, würde eine Beschädigung im Mantel verbleiben, die immer die Gefahr einer erneuten Beschädigung des darunterliegenden Luftschlauchs an dieser Schwachstelle des schützenden Mantels in sich bergen würde. In the case of tires which consist of an air tube which is of is surrounded by a separate jacket, which is the actual tread of the tire forms, both the air hose and the surrounding jacket from the self-healing material. If only the air hose from the material if there were any damage to the jacket, there would always be danger renewed damage to the air hose underneath Vulnerability of the protective cloak.
Auch kleine Risse bzw. Beschädigungen, die aufgrund einer Versprödung des Kunststoffs bzw. Gummis im Laufe der Zeit entstehen können, reparieren sich permanent automatisch. So kann vermieden werden, dass aus einem kleinen Riss bzw. einer kleinen Beschädigung eine große Beschädigung entsteht, die die Benutzung des Luftreifens oder Luftschlauchs einschränkt oder eine Reparatur bzw. einen Austausch erforderlich macht. Idealerweise erhöht dies die Lebensdauer des Luftreifens oder Luftschlauchs. Even small cracks or damage due to embrittlement of the Plastic or rubber can develop over time, repair themselves permanently automatic. This can prevent a small crack or a small damage a large damage arises that the Restricts use of the pneumatic tire or inner tube, or repairs or an exchange is necessary. Ideally, this will increase the lifespan of the Pneumatic tire or inner tube.
Die Erfindung hat allgemein den großen Vorteil, dass die Reparatur eines beschädigten Luftreifens oder Luftschlauchs erheblich vereinfacht wird. Beispielsweise bei Bussen oder Lastkraftwagen ist normalerweise eine solche Reparatur nur auf sehr aufwendige und kraftraubende Weise möglich. Erfindungsgemäß muss nun nur ein wenig Geduld aufgebracht werden, bevor der Luftreifen oder der Luftschlauch wieder aufgepumpt werden kann. Der Reifen muss nicht einmal vom Fahrzeug demontiert werden. The invention generally has the great advantage that the repair of a damaged tire or inner tube is considerably simplified. For buses or trucks, for example, this is usually the case Repairs only possible in a very complex and exhausting manner. According to the invention, only a little patience has to be applied before the Pneumatic tires or the air tube can be inflated again. The tire has to not even be dismantled from the vehicle.
Um die Kosten eines solchen Luftreifens oder Luftschlauchs so gering wie möglich zu halten, besteht der Luftreifen oder Luftschlauch nur an den gefährdeten Bereichen aus dem selbstheilenden Material. Dies kann bei einem Luftschlauch beispielsweise der Bereich sein, der unmittelbar unter der eigentlichen Lauffläche eines Mantels zum Liegen kommt. To keep the cost of such a pneumatic tire or inner tube as low as possible to hold, the pneumatic tire or inner tube only exists on the vulnerable Areas made of self-healing material. This can be the case with an air hose for example, the area immediately below the actual tread of a coat comes to rest.
