Abstract
Description
La présente invention concerne le domaine des bandages pneumatiques.The present invention relates to the field of pneumatic tires.
Un pneumatique ou pneu (suivant l'appellation courante de la langue Française) est une enveloppe de caoutchouc constituant le revêtement d'une chambre à air (ou faisant office de chambre à air) et fixée à la jante d'une roue. A tire or tire (according to the current name of the French language) is a rubber envelope constituting the coating of an inner tube (or acting as a tube) and attached to the rim of a wheel.
Les pneumatiques sont conçus d'un assemblage de matériaux pouvant permettre de contenir une quantité variable d'air comprimé tout en conservant à la fois rigidité et souplesse et offrant une bonne résistance à l'usure. The tires are designed with an assembly of materials that can accommodate a variable amount of compressed air while maintaining both rigidity and flexibility and good wear resistance.
Les pneumatiques représentent le point de contact entre un véhicule et la surface sur laquelle ce véhicule évolue. Ils permettent d'absorber certaines irrégularités de cette surface, une grande partie des vibrations et l'utilisation d'un dessin approprié de la bande de roulement leur apporte une grande diversité d'utilisation dans le rôle principal pour lequel ils ont été conçus: un rôle d'amortisseur et de facteur d'adhérence avec la surface en contact. Tires represent the point of contact between a vehicle and the surface on which the vehicle is moving. They make it possible to absorb certain irregularities of this surface, a large part of the vibrations and the use of an appropriate design of the tread bring them a great diversity of use in the main role for which they were designed: a role of damper and adhesion factor with the surface in contact.
Un des problèmes techniques liés à l'utilisation de pneumatiques est un problème de résistance à l'usure. One of the technical problems related to the use of tires is a problem of wear resistance.
La présente invention concerne précisément un dispositif mis en oeuvre lors de la fabrication d'un pneumatique dans le but d'en accroître la durée de vie de manière significative. The present invention specifically relates to a device used in the manufacture of a tire in order to increase the life significantly.
Dans une utilisation normale, la durée de vie d'un pneumatique dépend principalement de ses propriétés de résistance à l'usure de la bande de roulement. In normal use, the life of a tire depends mainly on its wear-resistant properties of the tread.
Il existe divers procédés qui permettent une résistance accrue à l'usure par apport de particules dures dans la composition de la gomme qui constitue la bande de roulement, mais on constate alors une perte d'adhérence due à la dureté du matériau. Il existe aussi des dispositions permettant à un pneumatique de voir ses sculptures retaillées à l'aide d'un outil adapté mais l'opération est délicate et les résultats imparfaits. There are various methods that allow increased resistance to hard particle wear in the gum compound which constitutes the tread, but there is a loss of adhesion due to the hardness of the material. There are also provisions allowing a tire to see his sculptures resized using a suitable tool but the operation is delicate and imperfect results.
Le dispositif, selon l'invention permet par exemple de doubler la durée de vie d'un pneumatique dans ses conditions habituelles d'utilisation sans utiliser de gomme plus dure dans la composition de la bande de roulement, ce qui altérerait les capacités d'adhérence. The device according to the invention makes it possible, for example, to double the service life of a tire under its usual conditions of use without using a harder rubber in the composition of the tread, which would impair the adhesion capacities. .
Lors de sa fabrication, le pneumatique devra comporter une bande de roulement plus épaisse (4) (fig.2) (par exemple deux fois plus épaisse par rapport à un pneu normal fig.1) présentant de ce fait des rainures plus profondes (5) (par exemple deux fois plus profondes). During manufacture, the tire must have a thicker tread (4) (fig.2) (for example twice as thick compared to a normal tire fig.1) thus having deeper grooves (5). ) (for example twice as deep).
Le dispositif consiste en une structure réticulée renforcée (6) dont la composition sera compatible avec l'utilisation du pneumatique et qui, après montage en usine, viendra combler en partie (par exemple la moitié) la profondeur des rainures (5) de la bande de roulement (4) du pneumatique prévue à cet effet. The device consists of a reinforced reticulated structure (6) whose composition will be compatible with the use of the tire and which, after assembly in the factory, will partially fill (for example half) the depth of the grooves (5) of the strip rolling (4) of the tire provided for this purpose.
Mis en place sur un pneumatique dont la bande de roulement est plus épaisse (4), le dispositif (6) a pour but de permettre au pneumatique de conserver les capacités dynamiques adéquates, modifiées par cette bande de roulement plus épaisse (4) mais nécessaires à son utilisation, il agit comme renfort à l'intérieur des sculptures (5) de la bande de roulement. Put in place on a tire whose tread is thicker (4), the device (6) is intended to allow the tire to maintain adequate dynamic capacities, modified by this tread thicker (4) but necessary when used, it acts as a reinforcement inside the tread (5) of the tread.
Suivant l'utilisation recherchée, il peut s'avérer opportun d'adapter le diamètre du pneumatique et judicieux d'apporter une coloration à la structure rapportée (6), ce qui, outre un aspect esthétique lui conférerait un rôle de témoin visuel rapide renseignant par sa présence ou son absence sur le potentiel d'usure disponible du pneumatique. Depending on the desired use, it may be appropriate to adapt the tire diameter and judicious to bring a color to the reported structure (6), which, in addition to an aesthetic appearance would confer a role of rapid visual witness inquiring by its presence or absence on the available wear potential of the tire.
Lorsqu'une usure limite de la bande de roulement est constatée, il suffit de procéder par coupure (par exemple à un emplacement de moindre épaisseur prévu à cet effet) à l'ablation du dispositif de structure rapportée (voir fig.3) afin de restaurer la bande de roulement qui est toujours d'une épaisseur équivalente à celle d'un pneu normal (7) avec des rainures ainsi libérées présentant le potentiel d'usure d'un pneumatique standard en état neuf. When a limit wear of the tread is noted, it is sufficient to proceed by cutting (for example at a location of less thickness provided for this purpose) to the ablation of the reported structure device (see fig.3) in order to restoring the tread which is always of a thickness equivalent to that of a normal tire (7) with grooves thus released having the wear potential of a standard tire in new condition.
Le dispositif selon l'invention permet d'accroître la durée de vie d'un pneumatique ce qui présente des avantages d'un point de vue écologique. The device according to the invention makes it possible to increase the service life of a tire, which has advantages from an ecological point of view.
Par sa conception, le dispositif permet aussi l'emploi d'une gomme plus tendre afin de privilégier si nécessaire les propriétés d'adhérence au sol par rapport à la longévité tout en conservant un potentiel d'usure augmenté. Dans ce cas, l'utilisation de gomme plus tendre devra être réservée à la bande de roulement et si l'utilisation de cette gomme plus tendre devait être étendue à l'ensemble du pneumatique, il conviendrait alors de renforcer de manière appropriée la structure même du pneumatique (la carcasse ) (3) afin de préserver la rigidité globale du pneumatique. By its design, the device also allows the use of a softer rubber to prefer if necessary the properties of adhesion to the ground compared to longevity while maintaining an increased wear potential. In this case, the use of softer rubber should be reserved for the tread and if the use of this softer rubber was to be extended to the tire as a whole, the structure should be appropriately reinforced. of the tire (the carcass) (3) in order to preserve the overall rigidity of the tire.
Le dispositif présente de plus l'avantage de réduire le risque de crevaison par perforation de la bande de roulement (4) car celle-ci est plus épaisse à l'origine mais aussi du fait de la présence de la structure (6) qui comble la moitié de la profondeur des rainures (5) pendant une partie de la durée de vie du pneumatique (par exemple la moitié). On peut dire que dans le cas de crevaison due à de petites perforations de la bande de roulement (corps étranger de petite taille), on verrait le risque de crevaison proportionnellement diminué de moitié (par exemple). The device also has the advantage of reducing the risk of perforation puncture of the tread (4) because it is thicker at the origin but also because of the presence of the structure (6) which fills half the depth of the grooves (5) during a part of the life of the tire (for example half). We can say that in the case of puncture due to small perforations of the tread (small foreign body), we would see the risk of puncture proportionally halved (for example).
