Abstract

The tyre is made from a number of layers, including at least one layer (2,3) of an elastic rubber and an outer tread (4). Between the outer layer (3) of elastic rubber and the tread (4) the tyre is equipped with a layer (5) of a material which can be vulcanised in place, e.g. of steel mesh or a coated textile. The additional layer can have a number of components, and it can extend across the whole width of the tyre or be intermittent across its width. ADVANTAGE - Increased tread strength and longer life.

Description

Pneu plein
L'invention concerne un pneu plein compose de plusieurs couches dans lequel au moins une couche en caoutchouc élastique porte un caoutchouc de bande de roulement exterieur, a faible usure.Solid tire
The invention relates to a solid tire composed of several layers in which at least one elastic rubber layer carries a low-wear outer tread rubber.

Par le EP-A 0 144 582, on connaSt un pneu plein présentant une couche intermédiaire sous forme de bande, en vue d'atteindre des vitesses êlevees. Cette couche intermédiaire est réalisée sous forme de bande annulaire et est composee soit en métal soit en corde. EP-A 0 144 582 discloses a solid tire having an intermediate layer in the form of a strip, in order to achieve high speeds. This intermediate layer is produced in the form of an annular band and is composed either of metal or of rope.

En outre, par le DE 32 29 580 C2 on connaSt un pneu plein avec une structure à trois couches. La masse de caoutchouc de base porte une couche de caoutchouc plastique, pourvue ensuite d'un caoutchouc de bandage de roulement a faible usure. Le coussin en caoutchouc fait à peu près 60 å 65 % de la quantité de caoutchouc totale du pneu. Il a été constaté que cette couche composée usuellement en caoutchouc naturel passait en réversion pendant la vulcanisation d'une nouvelle couche d'usure lors d'une réfection à chaud. Ceci a pour conséquence la perte des propriétés plastiques notamment l'augmentation du module de perte, ainsi que de la tangente delta a et ainsi de la résistance au roulement. Furthermore, from DE 32 29 580 C2 we know a solid tire with a three-layer structure. The base rubber mass carries a layer of plastic rubber, which is then provided with low-wear tread rubber. The rubber cushion makes about 60 to 65% of the total amount of rubber in the tire. It has been observed that this layer, usually composed of natural rubber, goes into reversion during the vulcanization of a new wear layer during a hot repair. This results in the loss of plastic properties, in particular the increase in the loss modulus, as well as in the tangent delta a and thus in the rolling resistance.

L'invention a pour but de proposer un pneu plein presentant après réfection à chaud une résistance de roulement correspondant a celle de pneus neufs. The object of the invention is to propose a solid tire having, after hot repair, a rolling resistance corresponding to that of new tires.

L'invention résout se problème par le fait qu'entre la couche en caoutchouc plastique et le caoutchouc de bande de roulement est prévu un bandage vulcanisable. The invention solves the problem that a vulcanizable tire is provided between the layer of plastic rubber and the tread rubber.

D'autres perfectionnements avantageux de l'invention sont caractérisés par le fait que
- le bandage est compose d'un treillis en acier ou textile revêtu. Other advantageous improvements of the invention are characterized in that
- the bandage is made up of a coated steel or textile mesh.

- le bandage est réalisé en caoutchouc sans support de résistance spécial , cependant avec une dureté augmenté et de bonne propriétés dynamiques. - the bandage is made of rubber without special resistance support, however with increased hardness and good dynamic properties.

- le bandage est composé de plusieurs couches. - the bandage is made up of several layers.

- le bandage s'étend sur toute la largeur du pneu plein. - the tire extends over the entire width of the solid tire.

- le bandage n'est prévu que partiellement. - the bandage is only partially planned.

Selon l'invention, le pneu présente un raidissement dans la direction circonférentielle. Le raidissement est dispose entre la couche en caoutchouc élastique et le caoutchouc de bande de roulement. According to the invention, the tire has a stiffening in the circumferential direction. The stiffening is arranged between the elastic rubber layer and the tread rubber.

Le raidissement est réalisé de manière correspondante à la sollicitation du pneu. The stiffening is carried out in a manner corresponding to the stress on the tire.

Des exemples de réalisations de l'invention sont représentés dans le dessin, dans lequel
La figure 1 représente un pneu plein en coupe transversale,
les figures 2 a 4 représentent un pneu plein selon la figure 1, avec d'autres modes de réalisation du bandage.Examples of embodiments of the invention are shown in the drawing, in which
FIG. 1 represents a solid tire in cross section,
Figures 2 to 4 show a solid tire according to Figure 1, with other embodiments of the tire.

Selon la figure 1 un pneu plein 1 est compose d'une couche de base, d'une couche en caoutchouc plastique 3, d'un caoutchouc de bande de roulement 4 et d'un bandage 5. According to FIG. 1, a solid tire 1 is composed of a base layer, a layer of plastic rubber 3, a tread rubber 4 and a tire 5.

Le bandage est composé d'un treillis en acier recouvert. Il peut etre composé d'un treillis en textile ou bien d'un caoutchouc, sans support de résistance spéciale. Ce caoutchouc sans support de resistance spéciale présente une dureté augmentée et de bonnes propriétés dynamiques. The bandage is composed of a covered steel mesh. It can be made of a textile mesh or a rubber, without special resistance support. This rubber without a special resistance support has increased hardness and good dynamic properties.

Le bandage 5 est situe sur une interface 6 et s'étend jusqu'aux zones marginales 7, 8, sur toute la largeur 9 de l'interface 6. The bandage 5 is located on an interface 6 and extends to the marginal zones 7, 8, over the entire width 9 of the interface 6.

Les pneus pleins 10 a 12 des figures 2 a 4 présentent la même structure que le pneu plein 1 de la figure 1. Seuls les bandages 13 3 15 décrits ci-après plus en détail sont différents. The solid tires 10 to 12 of FIGS. 2 to 4 have the same structure as the solid tire 1 of FIG. 1. Only the tires 13 3 15 described below in more detail are different.

Selon la figure 2, le bandage 13 est compose de plusieurs couches en caoutchouc, sans support de résistance spécial, cependant avec une dureté augmenté et de bonnes propriétés dynamiques. According to Figure 2, the bandage 13 is composed of several layers of rubber, without special resistance support, however with increased hardness and good dynamic properties.

Le bandage 14 s'étend, de manière correspondante la figure 3, sur toute la largeur 20 du pneu plein 11. The tire 14 extends, correspondingly in FIG. 3, over the entire width 20 of the solid tire 11.

Selon la figure 4, le bandage 15 est composé d'anneaux 21 à 23 disposés les uns 3 coté des autres. According to Figure 4, the bandage 15 is composed of rings 21 to 23 arranged one next to the other.

Le matériau prevu est un treillis en textile. La largeur des anneaux et l'agencement des anneaux sur l'interface 6 dépendent de la sollicitation â laquelle le pneu plein 12 est soumis. The material provided is a textile lattice. The width of the rings and the arrangement of the rings on the interface 6 depend on the stress to which the solid tire 12 is subjected.
