Abstract
Pneumatic tyre for mounting on a metal rim of a vehicle wheel comprises >=1 electrical conductor part of which comes into contact with the rim, and part of which extends to the outer surface of the tyre which comes into contact with the ground. The tyre may also have a conductive outer layer, e.g. an elastomer to which conductive rubber is added.The arrangement allows permanent efficient earthing of the metal mass of the vehicle, whether earthbound or airborne, to prevent a dangerous accumulation of static electricity in the vehicle. The tyre is easy to mfr., and its cost is only slightly greater than that of a conventional tyre.
Description
La présente invention a pour objet un pneumatique destiné à être fixé sur une jante métallique d'une roue d'un véhicule.
On sait que les pneumatiques connus isolent électriquement le véhicule du sol. Cette isolation est la cause d'une accumulation d'électricité statique, sur la surface de la carrosserie du véhicule, due à la friction de l'air et au passage dans des zones à champ électrique élevé. Cette charge électrique de la carrosserie est la cause de nombreux inconvénients: secousses électriques lorsque l'on touche le véhicule, étincelles pouvant allumer des vapeurs de carburant lors du remplissage du réservoir, malaises divers, etc.
On a tenté de pallier ces inconvénients en fixant, sur le châssis du véhicule, une bande conductrice lourde qui, frottant sur le sol, relie électriquement la masse métallique au sol et décharge ainsi le véhicule. Toutefois, ces bandes conductrices, frottant sur le sol, s'usent assez rapidement. D'autre part, le contact électrique entre la bande et le sol n'est pas continu: la bande flotte à grande vitesse; le contact est de qualité médiocre à l'arrêt du véhicule, les surfaces en contact étant minimes.
Le but de la présente invention est d'obtenir, au moyen d'un pneumatique spécialement conçu, une mise à la terre permanente et efficace de la masse métallique du véhicule, ce véhicule pouvant être terrestre ou aérien.
Le pneumatique selon l'invention est caractérisé par le fait qu'il comporte au moins un conducteur électrique dont une partie est destinée à venir en contact avec ladite jante métallique du véhicule, une autre partie de ce conducteur affleurant la surface de roulement du pneumatique destinée à venir en contact avec le sol.
Le dessin annexé représente, à titre d'exemple, deux formes d'exécution de l'invention:
la fig. 1 est une vue schématique, en coupe radiale, de la première forme d'exécution,
la fig. 2 est une vue schématique, en coupe radiale, de la deuxième forme d'exécution.
Le pneumatique, schématiquement représenté en coupe axiale en fig. 1, est formé d'une enveloppe 1 renforcée par une carcasse 2, de préférence en acier. Ce pneumatique a été fixé, comme connu, sur la jante métallique 4 d'une roue d'un véhicule non représenté. Cette jante 4 est en contact électrique avec le châssis métallique de ce véhicule.
Le pneumatique comporte des conducteurs électriques 5 qui sont en contact avec la jante 4, d'une part, et, d'autre part,
affleurent la surface de roulement 6 du pneumatique et sont ainsi
en contact avec le sol. Par ces conducteurs 5, le châssis du véhi
cule est donc en contact constant avec le sol, une charge électrique
de ce véhicule par rapport au sol est donc impossible. Dans une
forme préférée de l'invention, ces fils métalliques 5 sont tissés avec
ceux de la carcasse, traversant la gomme en regard du chemin de
roulement 6 et en regard de la jante 4.
Le pneumatique représenté schématiquement en fig. 2 com
prend une enveloppe 11 sur laquelle est appliquée de façon permanente une couche de matière conductrice 12, représentée au
dessin de façon agrandie. Cette couche sera, de préférence, une
couche d'élastomère dopé tel qu'un caoutchouc conducteur, elle
recouvrira tout ou partie de la surface extérieure de l'enve
loppe 11. Cette couche 12 relie électriquement la surface de
roulement 13 de la jante métallique 14, cette dernière étant en
contact électrique avec l'ensemble du véhicule.
Par cette description, on voit la simplicité de fabrication d'un
tel pneumatique et son efficacité pour lutter contre l'accumulation
dangereuse d'électricité statique par un véhicule, que celui-ci soit
terrestre (automobile, camion, etc.) ou aérien (avion ou hélicop
tère).
Le prix de revient d'un pneumatique selon l'invention n'est
que très légèrement supérieur à celui d'un pneumatique courant.

The present invention relates to a tire intended to be fixed to a metal rim of a wheel of a vehicle.
It is known that the known tires electrically insulate the vehicle from the ground. This insulation is the cause of an accumulation of static electricity, on the surface of the body of the vehicle, due to the friction of the air and the passage in areas with high electric field. This electrical charge on the bodywork is the cause of many drawbacks: electric shocks when you touch the vehicle, sparks that can ignite fuel vapors when filling the tank, various complaints, etc.
Attempts have been made to overcome these drawbacks by fixing a heavy conductive strip on the vehicle frame which, rubbing on the ground, electrically connects the metal mass to the ground and thus discharges the vehicle. However, these conductive strips, rubbing on the ground, wear out quite quickly. On the other hand, the electrical contact between the strip and the ground is not continuous: the strip floats at high speed; the contact is of poor quality when the vehicle is stationary, the contact surfaces being minimal.
The aim of the present invention is to obtain, by means of a specially designed tire, a permanent and efficient earthing of the metallic mass of the vehicle, this vehicle possibly being land or air.
The tire according to the invention is characterized by the fact that it comprises at least one electrical conductor, part of which is intended to come into contact with said metal rim of the vehicle, another part of this conductor flush with the tread surface of the tire intended for to come into contact with the ground.
The appended drawing represents, by way of example, two embodiments of the invention:
fig. 1 is a schematic view, in radial section, of the first embodiment,
fig. 2 is a schematic view, in radial section, of the second embodiment.
The tire, schematically shown in axial section in FIG. 1, is formed of a casing 1 reinforced by a carcass 2, preferably of steel. This tire has been fixed, as known, on the metal rim 4 of a wheel of a vehicle, not shown. This rim 4 is in electrical contact with the metal frame of this vehicle.
The tire comprises electrical conductors 5 which are in contact with the rim 4, on the one hand, and, on the other hand,
are flush with the tread surface 6 of the tire and are thus
in contact with the ground. By these 5 conductors, the vehicle chassis
cule is therefore in constant contact with the ground, an electric charge
of this vehicle relative to the ground is therefore impossible. In
preferred form of the invention, these metallic threads 5 are woven with
those of the carcass, crossing the rubber opposite the path of
bearing 6 and facing the rim 4.
The tire shown schematically in FIG. 2 com
takes an envelope 11 on which is permanently applied a layer of conductive material 12, shown in
enlarged drawing. This layer will preferably be a
layer of doped elastomer such as a conductive rubber, it
will cover all or part of the outer surface of the envelope
loppe 11. This layer 12 electrically connects the surface of
bearing 13 of the metal rim 14, the latter being in
electrical contact with the entire vehicle.
By this description, we see the simplicity of manufacturing a
such tire and its effectiveness in combating accumulation
dangerous static electricity by a vehicle, whether it is
land (automobile, truck, etc.) or air (plane or helicopter
ter).
The cost price of a tire according to the invention is not
that very slightly higher than that of a common tire.
CLAIM
Tire intended to be fixed on a metal rim with a
wheel of a vehicle, characterized in that it comprises at least
an electrical conductor, part of which is intended to come in
contact with said vehicle rim, another part of this
conductor flush with the tread surface of the tire
intended to come into contact with the ground.
SUB-CLAIMS
1. A tire according to claim, characterized by the fact
that metallic electrical conductors come into contact
on the one hand, with the rim and, on the other hand, with the ground.
2. A tire according to claim, characterized by the fact
that it has a conductive outer layer.
