The invention concerns an anti-vibration balance weight for motor vehicle, of the wheel balance type or noise damper type, produced by injection moulding of a thermoplastic material (in particular of the polyamide, polypropylene or polycarbonate type) containing a weight filling of metal particles. Preferably, the weight filling consists of tungsten powder which represents between 80 and 90 wt. % of the final material.

Description

MASSE ANTIVIBRATOIRE POUR VÉHICULE AUTOMOBILE La présente invention concerne une nouvelle structure de masse antivibratoire pour véhicule automobile, du genre masse d'équilibrage de roue ou étouffeur de bruit. The present invention relates to a new structure for an anti-vibration mass for a motor vehicle, of the wheel balancing mass or noise suppressor type.
Les masses antivibratoires installées sur les véhicules automobiles sont de deux types principaux : les masses d'équilibrage de roues et les étouffeurs de bruits.The anti-vibration masses installed on motor vehicles are of two main types: wheel balancing masses and noise suppressors.
Les masses d'équilibrage pour roues de véhicules sont constituées d'une barrette ou plaque pesante, généralement en plomb, agrafée ou collée sur le rebord de la jante.Balance weights for vehicle wheels consist of a heavy bar or plate, usually made of lead, stapled or glued to the rim flange.
Les étouffeurs de bruits se présentent en règle générale sous la forme de masses en plomb qui sont fixées à des endroits judicieusement choisis du châssis du véhicule au moyen de systèmes vis-écrou associés à des organes d'amortissement élastiques.Noise suppressors are generally in the form of lead weights which are fixed at carefully chosen locations on the vehicle chassis by means of screw-nut systems associated with elastic damping members.
Mais l'usage du plomb est de plus en plus réglementé, en raison notamment de sa toxicité et des problèmes environnementaux ou écologiques qu'il pose ; il est en conséquence intéressant, en particulier dans ce domaine des masses antivibratoires pour véhicules automobiles, de trouver des substituts à ce matériau, ou tout au moins de limiter ses possibilités de dissémination par contact.But the use of lead is increasingly regulated, in particular because of its toxicity and the environmental or ecological problems it poses; it is therefore advantageous, in particular in this field of anti-vibration masses for motor vehicles, to find substitutes for this material, or at least to limit its possibilities of dissemination by contact.
A cet effet, la masse antivibratoire conforme à la présente invention est réalisée par moulage-injection d'une matière thermoplastique renfermant une charge pondérale constituée de particules métalliques.To this end, the anti-vibration mass in accordance with the present invention is produced by injection molding of a thermoplastic material containing a weight load consisting of metal particles.
La masse antivibratoire correspondante est très simple à fabriquer après mélange homogène de la base plastique avec la charge métallique. Cette technique permet d'obtenir très facilement toute forme de produit chimiquement stable, la charge métallique incluse dans la base plastique étant rendue absolument inerte.The corresponding anti-vibration mass is very simple to manufacture after homogeneous mixing of the plastic base with the metallic load. This technique makes it very easy to obtain any form of chemically stable product, the metallic charge included in the plastic base being made absolutely inert.
La matière thermoplastique mise en œuvre est de préférence choisie parmi le polyamide, le polypropylene ou le polycarbonate. La charge pondérale métallique peut se présenter sous la forme de paillettes ou de fibres, mais on l'utilise de préférence sous la forme d'une poudre dont les dimensions de particules sont comprises entre 0,5 et 300 μm (et de préférence comprises entre 5 μm et 50 μm).The thermoplastic material used is preferably chosen from polyamide, polypropylene or polycarbonate. The metallic weight charge may be in the form of flakes or fibers, but it is preferably used in the form of a powder whose particle sizes are between 0.5 and 300 μm (and preferably between 5 μm and 50 μm).
On utilise avantageusement des métaux de forte densité tels le plomb, l'étain, le cuivre, tungstène, le baryum, le bismuth ou des dérivés de ces métaux (notamment des oxydes ou alliages).Advantageously, high density metals such as lead, tin, copper, tungsten, barium, bismuth or derivatives of these metals (in particular oxides or alloys) are used.
Il est également possible d'utiliser des mélanges de métaux, ou encore des particules d'un alliage métallique comme le bronze ou l'acier.It is also possible to use mixtures of metals, or even particles of a metal alloy such as bronze or steel.
La nature de la charge métallique, et son taux d'incorporation dans la base thermoplastique sont adaptés pour obtenir un matériau composite moulé dont la densité est supérieure à 8, et de préférence comprise entre 10 et 12, c'est-à-dire proche de la densité du plomb utilisé de manière traditionnelle.The nature of the metallic filler, and its rate of incorporation into the thermoplastic base are suitable for obtaining a molded composite material whose density is greater than 8, and preferably between 10 and 12, that is to say close to the density of lead conventionally used.
Selon une forme de réalisation préférée, et de manière à obtenir un produit final peu onéreux dont les caractéristiques massiques se rapprochent de celles du plomb, la charge pondérale est constituée de particules de tungstène, ou d'un dérivé du tungstène, présentes dans des proportions comprises entre 80 et 95 % du poids du-matériau final.-According to a preferred embodiment, and in order to obtain an inexpensive final product whose mass characteristics approach those of lead, the weight charge consists of tungsten particles, or of a tungsten derivative, present in proportions between 80 and 95% of the weight of the final material.
De préférence encore, les particules de tungstène (ou dérivé) représentent environ 90 % du poids du matériau final.More preferably, the tungsten (or derivative) particles represent approximately 90% of the weight of the final material.
Les figures 1 et 2 annexées sont des vues en coupe, respectivement d'une masse d'équilibrage de roues et d'un étouffeur de bruit, réalisés par moulage-injection de matière thermoplastique contenant une charge pondérale métallique.Figures 1 and 2 attached are sectional views, respectively of a wheel balancing mass and a noise suppressor, produced by injection molding of thermoplastic material containing a metallic weight charge.
Ces deux masses antivibratoires sont obtenues après mélange homogène de la charge pondérale métallique avec la matière thermoplastique de base.These two anti-vibration masses are obtained after homogeneous mixing of the metallic weight charge with the basic thermoplastic material.
Sur ces deux figures, on remarque la répartition homogène des particules métalliques incluses dans la matière thermoplastique. Plus les particules métalliques utilisées sont fines, moins elles sont visibles et accessibles, notamment au niveau de la surface externe de la pièce.In these two figures, the homogeneous distribution of the metallic particles included in the thermoplastic material is noted. The finer the metal particles used, the less visible and accessible they are, in particular at the level of the external surface of the part.
