Description

Es ist bekannt, mit Luft gefüllte Gummikörper, wie beispielsweise die Schläuche von Automobilreifen, dadurch gegen das Entweichen von Luft bei Verletzungen der Umhüllung zu schützen, daß die Wandung des Gummikörpers mit einer Schwammgummieinlage versehen oder umkleidet wird. Bei Verletzungen der Wandung des Gummikörpers durch von außen hineingestoßeneIt is known to use rubber bodies filled with air, such as the hoses from Automobile tires, thereby preventing air from escaping if the casing is damaged to protect that the wall of the rubber body is provided or covered with a sponge rubber insert. at Injuries to the wall of the rubber body from being pushed in from the outside

ίο Nägel usw. sucht die gleichfalls verletzte Schwammgummieinlage durch ihr Zusammenziehungsvermögen das entstandene Loch selbsttätig wieder zu verschließen, so daß keine Luft aus dem Gummikörper entweichen kann. Gleichfalls ist bekannt, die Schwammgummieinlage mit einer geeigneten Flüssigkeit zu tränken, um die Elastizität und das Zusammenziehungsvermögen der Schwammgummieinlage zu verstärken und bindend zu wirken.ίο Nails etc. is looking for the one who is also injured Sponge rubber insert to close the resulting hole automatically by its ability to contract, so that no air can escape from the rubber body. The sponge rubber insert is also known soak with a suitable liquid in order to maintain the elasticity and contractibility of the sponge rubber insert to strengthen and to have a binding effect.

Diese bekannten selbsttätigen Dichtungsmittel sind jedoch noch unvollkommen und nicht geeignet, einen absolut zuverlässigen Schutz gegen das Entweichen von Luft zu bieten. Der Grund liegt zum Teil darin, daß sich die Schwammgummieinlage besonders durch das Aufpumpen des Reifens in angespanntem Zustand befindet, wodurch ihr Zusammenziehungsvermögen gestört ist.However, these known automatic sealants are still imperfect and not suitable to provide absolutely reliable protection against the escape of air Offer. Part of the reason is that the sponge rubber insert is special by inflating the tire is in a tense state, reducing its ability to contract is disturbed.

Gegenstand der Erfindung ist eine Einlage, bei der diese Mängel behoben sind.The subject of the invention is an insert in which these deficiencies are eliminated.

Die erfindungsgemäße Einlage ist im wesentlichen dadurch gekennzeichnet, daß die an sich bekannte, die Wandung bildende oder umgebende imprägnierte Schwammgummieinlage von einer gespannten Gummihaut aus Schlauchgummi umschlossen und unter Spannung gehalten wird.The insert according to the invention is essentially characterized in that the known, the wall forming or surrounding impregnated sponge rubber insert is enclosed by a stretched rubber skin made of tubular rubber and kept under tension.

Die Zeichnung veranschaulicht einen Automobilluftreifen im Schnitt, welcher mit einer erfindungsgemäßen Einlage versehen ist. Die dichtende Wandung besteht also gemäß der Erfindung aus drei Gummilagen. In der Mitte befindet sich der imprägnierte Schwammgummi a, während außen herum als Umhüllung gespannte Schlauchgummiplatten b angeordnet sind. Diese Einlage ist zwischen Mantel d und Luftschlauch c eingelegt und kann mit letzterem fest verbunden werden. Da der gespannte Schlauchgummi das Bestreben hat, sich zusammenzuziehen, befindet sich der Schwammgummi α dauernd in zusammengepreßtem Zustand. Wird eine derartige Wandung von einem Nagel o.dgl. durchstochen, so legt sich der Schwammgummi fest um den Nagel und verhindert ein Austreten der Luft. Wird der Nagel herausgezogen, so schließt der Schwammgummi auf Grund seiner inneren Spannung und seiner Imprägnierungsfiüssigkeit das Loch, gleichzeitig tritt als neues Moment eine kleine ungleichmäßige Verschiebung der umhüllenden Weichblattgummilagen b ein, wodurch das Loch abermals verschlossen wird.The drawing illustrates a pneumatic automobile tire in section, which is provided with an insert according to the invention. According to the invention, the sealing wall thus consists of three rubber layers. In the middle is the impregnated sponge rubber a, while outside around it, stretched rubber hose plates b are arranged as a cover. This insert is inserted between the jacket d and the air hose c and can be firmly connected to the latter. Since the stretched tubular rubber tends to contract, the sponge rubber α is constantly in a compressed state. If such a wall of a nail or the like. pierced, so the sponge rubber is firmly attached to the nail and prevents the air from escaping. If the nail is pulled out, the sponge rubber closes the hole due to its internal tension and its impregnation liquid, at the same time a small, uneven shift of the enveloping soft-leaf rubber layers b occurs , which closes the hole again.
