Description

PROCEDE DE FABRICATION D'UNE MASSE D'EQUILIBRAGE POUR ROUE DE VEHICULES ET MASSE OBTENUE.METHOD FOR MANUFACTURING BALANCING MASS FOR VEHICLE WHEEL AND MASS OBTAINED
La présente invention concerne le domaine de la fabrication des équipements automobiles et a pour objet un procédé de fabrication d'une masse d'équilibrage pour roues de véhicules, constituée d'une masse destinée à être rapportée sur la jante d'une roue au moyen d'une agrafe.The present invention relates to the field of the manufacture of automotive equipment and relates to a method of manufacturing a balance weight for vehicle wheels, consisting of a mass intended to be attached to the rim of a wheel by means of a staple.
L'invention concerne également les masses d'équilibrage issues de la mise en oeuvre dudit procédé.The invention also relates to the balancing masses resulting from the implementation of said method.
Obtenir un parfait équilibrage des roues est une opération fondamentale concernant tous les types de véhicules, et destinée aussi bien à prévenir une usure prématurée des organes de suspension, des organes de direction ou des pneumatiques, que d'éviter un inconfort de conduite.Achieving perfect wheel balancing is a fundamental operation for all types of vehicles, designed to prevent premature wear of suspension components, steering devices or tires, as well as to avoid driving discomfort.
L'équilibrage des roues est également une opération incontournable, car le fait de monter un pneu neuf sur une roue nuit naturellement à son équilibre, que ce soit en raison de l'excentricité des pneumatiques, d'un décentrage radial ou latéral de la jante ou d'une position inadéquate de la valve.Balancing the wheels is also an essential operation, because mounting a new tire on a wheel naturally interferes with its balance, whether due to the eccentricity of the tires, a radial or lateral decentering of the rim. or improper position of the valve.
D'autre part, l'utilisation normale d'un véhicule et la moindre irrégularité d'usure des pneus issue de quelques freinages brusques modifient également l'équilibre des roues.On the other hand, the normal use of a vehicle and the slightest irregularity of tire wear resulting from a few sudden braking also modify the balance of the wheels.
De manière classique, l'équilibrage d'une roue consiste, entre autres, à obtenir un équilibre statique au travers d'une ou plusieurs masses d'équilibrage, disposées entre la jante et le pneu, à l'opposé de la masse déséquilibrante, au moyen d'une agrafe.In a conventional manner, the balancing of a wheel consists, inter alia, in obtaining a static equilibrium through one or more balancing masses, disposed between the rim and the tire, opposite the unbalancing mass, by means of a staple.
Jusqu'à encore récemment, il était d'usage d'utiliser des masses d'équilibrage réalisées en plomb, telles que celles décrites dans les documents FR 1.237.596, DE 31 18 222 et US 2.221.747. A l'heure actuelle cependant, les fabricants se tournent plutôt vers d'autres matériaux, notamment davantage compatibles avec les exigences réglementaires en matière environnementale les plus récentes. L'emploi de matériaux autres que le plomb soulève à présent de nouveaux problèmes, et implique en outre la mise au point de procédés de fabrication adaptés.Until recently, it was customary to use balance weights made of lead, such as those described in documents FR 1,237,596, DE 31 18 222 and US 2,221,747. AT currently, however, manufacturers are turning to other materials, including more consistent with the latest environmental regulatory requirements. The use of materials other than lead now raises new problems, and also involves the development of suitable manufacturing processes.
Plusieurs publications traitent d'ores et déjà de masses d'équilibrage conçues au moyen de matériaux autres que le plomb, et de leur procédé de fabrication.Several publications already deal with balancing masses designed using materials other than lead, and their manufacturing process.
La demande de brevet EP 1.113.188, par exemple, décrit une masse d'équilibrage réalisée par frittage d'un matériau inoxydable, à savoir un alliage de fer comportant au moins 12% en poids de chrome. La masse est pourvue d'une fente en forme de "V" dans laquelle on positionne conjointement une lame d'acier faisant office d'agrafe et une lame de brasure avant de porter le tout à une température supérieure à 11000C.The patent application EP 1.113.188, for example, describes a balancing mass produced by sintering a stainless material, namely an iron alloy comprising at least 12% by weight of chromium. The mass is provided with a "V" -shaped slot in which a steel plate acting as a staple and a solder blade is positioned before bringing the whole to a temperature above 1100 ° C.
Le document DE 101.02.321 concerne une masse d'équilibrage en zinc ou en alliage de zinc pouvant être fixée soit au moyen d'une bande collante, soit au moyen d'une agrafe en acier sur laquelle la masse est surmoulée.Document DE 101.02.321 relates to a balancing mass of zinc or zinc alloy that can be fixed either by means of a sticky tape or by means of a steel clip on which the mass is overmolded.
Le document EP 1.355.084 décrit des masses d'équilibrage en zinc ou en alliage de zinc qui comportent au moins une gorge qui permet d'adapter la courbure de la masse en fonction du rayon de la jante.The document EP 1.355.084 describes balancing masses of zinc or zinc alloy which comprise at least one groove which makes it possible to adapt the curvature of the mass as a function of the radius of the rim.
Le document WO2004/007993 a trait à une masse d'équilibrage conçue en zinc ou en alliage de zinc et reliée à une agrafe en acier.WO2004 / 007993 relates to a balancing mass designed zinc or zinc alloy and connected to a steel clip.
Le document WO 2004/025139 a pour objet une masse d'équilibrage réalisée en zinc ou en alliage de zinc, comportant une agrafe noyée dans la masse par surmoulage, l'ensemble étant recouvert d'un revêtement anticorrosion.WO 2004/025139 relates to a balancing mass made of zinc or zinc alloy, comprising a staple embedded in the mass by overmolding, the assembly being covered with an anticorrosive coating.

Les avantages et les caractéristiques du procédé selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the method according to the invention will become more clearly apparent from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé la figure unique représente une vue schématique en perspective et en éclaté d'un mode de réalisation particulier d'une masse d'équilibrage conforme à l'invention. La présente invention a pour objet un procédé de fabrication de masses d'équilibrage 1 pour roues de véhicule constituées chacune d'une masse 2 destinée à être rapportée sur la jante, non représentée, d'une roue au moyen d'une agrafe 3.In the accompanying drawing the single figure shows a diagrammatic perspective and exploded view of a particular embodiment of a balancing mass according to the invention. The subject of the present invention is a method for manufacturing balancing weights 1 for vehicle wheels, each consisting of a mass 2 intended to be attached to the rim, not shown, of a wheel by means of a staple 3.
Selon l'invention, un tel procédé prévoit de ménager dans l'épaisseur de ladite masse 2 une cavité 4 destinée à accueillir une partie 5 de l'agrafe 3, puis de déposer de la colle dans la cavité 4, de sorte à introduire la partie 5 et fixer l'agrafe 3 par collage.According to the invention, such a method provides for forming in the thickness of said mass 2 a cavity 4 intended to receive a portion 5 of the staple 3, then depositing glue in the cavity 4, so as to introduce the part 5 and fix the clip 3 by gluing.
Avantageusement, selon une caractéristique propre à l'invention, l'on utilise une masse 2 injectée en alliage de zinc, permettant d'éviter les problèmes liés à l'utilisation du plomb aussi bien en termes environnementaux, qu'en termes de corrosion. De manière avantageuse, la masse 2 est réalisée en zamak.Advantageously, according to a characteristic of the invention, it uses a mass 2 injected zinc alloy, to avoid the problems associated with the use of lead both in environmental terms, in terms of corrosion.
