Abstract

In a pneumatic tyre having a tread reinforced by a layer of metal yarns protecting the tread plies which lie on a subconstruction with meridionally directed cord ply yarns, the reinforcing layer yarns take the form of a braided or interwoven net with a mesh width 1.5-6.0 times the yarn dia, which is pref. 0.1-0.3 mm, from metal with modulus of elasticity of 1x104-5x105 kp/cm2.

Description

LUFTREIFENDECKE Die Erfindung betrifft Luftreifendecken für Luftkraftwagen. Pneumatic tire covers The invention relates to pneumatic tire covers for air vehicles.

Bei den bekannten Konstruktionen enthalt die Luftreilendecke eine Lauffläche, die durch eine Schicht aus Eetallfäden bewehrt ist. In the known constructions, the air deck contains a Tread reinforced with a layer of metal threads.

Die Lauffläche schütz die Laufflächeneinlage, welche auf den Unterbau mit meridional gerichteten Kordgewebefäden liegt. The tread protects the tread insert, which is placed on the substructure with meridional oriented cord fabric threads.

Die Bewehrung der Lauffläche durch Metailfäden bei den bekannten Konstruktionen erhöht nur wenig und nicht ausreichend die Festigkeit der Luftreifendecke und verlängert somit auch wenig die Lebensdauer. The reinforcement of the tread by metal threads in the known Constructions only slightly and insufficiently increase the strength of the tire cover and therefore does not extend the service life much.

Die Erfindung bezweckt die Beseitigung des erwähnten Mangels. The invention aims to remedy the above-mentioned deficiency.

Der Erfindung liegt die Aufgabe zugrunde, eine solche Bauart der Luftreifendecke zu entwickeln, bei der die Festigkeit der Decke im Bereich der Lauffläche werentlich erhöht ist. The invention is based on the object of such a type of To develop pneumatic tire cover, in which the strength of the cover in the area of the tread is actually increased.

Zur Lösung der erstellten Aufgabe wurde eine Luftreifendeckte entwickelt, die eine lauffläche enthält, welche durch eine aus Metallfäden bestehenden Schicht bewehrt ist, die die Laufflächeneinlage schützt, welche auf den Urterbau mit meridional gerichteten Kordgewebefäden liegt. Gemäß der Erfindung sind die Fäden der Bewehrungsschicht in Form eines Netzes geflechten, dessen Meschenweite umd das 1,5 bis 6,0 fache das Fadendurchmesser übersteigt. To solve the created task, a pneumatic tire cover was developed, which contains a running surface, which is covered by a layer consisting of metal threads is reinforced, which protects the tread insert, which on the original structure with meridional directed cord fabric threads. According to the invention, the threads are the reinforcement layer braided in the form of a net, the mesh size of which is 1.5 to 6.0 times that Exceeds thread diameter.

Es ist zweckmäßig, daß der Faden der Bewehrungsschicht einen Durchmesser von 0,1 bis 0,3 mm aufweist und aus Metall mit einem Elastizitätsmodul im Bereich von 1.104 bis kp/cm2 gefertigt wird. It is useful that the thread of the reinforcement layer has a diameter from 0.1 to 0.3 mm and made of metal with a modulus of elasticity in the range is manufactured from 1,104 to kp / cm2.

Eine derartige Bewehrung des Laufstreifens erhöht die-Festigkeit des Luftreifens im Bereich der Lauffläche und verlängert die Lebensdauer der Luftreifendecke. Such a reinforcement of the tread increases the strength of the tire in the area of the tread and extends the service life of the tire cover.

Die Bewehrung der Lauffläche durch Fäden mit einen Durchmesser von 0,1 bis 0,3 mm und aus Metall mit einen Elastizitätsmodul im Bereich von l.lG4 bis 5.155 kp/cm² gewährleistet die erforderlichen Elastizität und Festigkeit des B1ewehrungsschicht. The reinforcement of the tread by threads with a diameter of 0.1 to 0.3 mm and made of metal with a modulus of elasticity in the range from 1.lG4 to 5,155 kp / cm² ensures the required elasticity and strength of Reinforcement layer.

Nachstehend wird die Erfindung anhand der Beschreibung eines Ausführungsbeispieles und der beigelegten Zeichnungen näher erläutert. Es zeigt Fig. 1 Konstruktion der erfindungsgemäßen Luftreifendecke; Fi. 2 stufenartiger Deckenschnitt im Bereich der Lauffläche. The invention is explained below with the aid of the description of an exemplary embodiment and the accompanying drawings explained in more detail. It shows Fig. 1 construction of pneumatic tire cover according to the invention; Fi. 2 step-like ceiling cut in the area the tread.

Die Luftreifendecke enthält eine Lauffläche 1 (fig. 1,2), die durch eine Schicht 2 bewehrt. ist, die aus Metall fäden mit einem Durchmesser von 0,1 bis 0,3 m, welche in Meridional-und Umfangsrichtung angeordnet und als Netz geflochten sind, dessen Maschenweite um das 1,5 bis 0,Gfache das Fadendurchmesser übersteigt. The tire cover contains a tread 1 (fig. 1,2), which by a layer 2 reinforced. is made of metal threads with a diameter of 0.1 up to 0.3 m, which are arranged in meridional and circumferential directions and braided as a network with a mesh size of 1.5 to 0. G times the thread diameter.

Die Lauffläche 1 schützt eine Laufflächeneinlage 3, die auf dem mit meridional gerichteten Kordgewebefäden versehenen Unterbau 4 liegt. The tread 1 protects a tread insert 3, which is on the with Meridionally directed cord fabric threads provided substructure 4 lies.

Die Bewehrungsschicht 2 kann in der Lauffläche 1 entweder wie in Fig. 1, oder direkt über der Einlage 3 gemäß Fig, 2 angeordnet werden. The reinforcement layer 2 can be in the tread 1 either as in Fig. 1, or be arranged directly above the insert 3 according to FIG.

Die Bewehrungsschicht 2 kann aus vermessingtem Stahldraht oder Metall mit einem Elastizitätsmodul bis kp/cm² gefertigt werden. The reinforcement layer 2 can be made of brass-plated steel wire or metal can be manufactured with a modulus of elasticity of up to kp / cm².

Nachstehend wird eine Tabelle der Probeergebnisse von Luftreifendecken angeführt. The following is a table of the test results of pneumatic tire covers cited.
