CA 2278719

A noise barrier in a road wheel assembly is described: the barrier can be made from any suitable noise absorbing/deadening material manufactured to exacting safety specifications as far as width, thickness and retention. A solid synthetic or natural rubber or plastics material which is an extremely poor medium for transmitting vibrations can be used. For example a specially prepared durable rubber extruded and vulcanised between two steel or other metal rings or plates situated between a road wheel rim and a wheel hub assembly is suitable. The invention can be incorporated into a new wheel or as a modification to an existing wheel.

La présente invention concerne une barrière antibruit qui peut équiper un roue de véhicule routier. Cette barrière, que l'on peut réaliser dans n'importe quel matériau convenant pour absorber ou amortir le bruit, peut se fabriquer en respectant des normes de sécurité, notamment en ce qui concerne la largeur, l'épaisseur et la fixation. On peut utiliser à cet effet de la gomme solide synthétique ou naturelle ou de la matière plastique, dans la mesure où c'est un matériau transmettant extrêmement mal les vibrations. Il est ainsi possible d'utiliser une gomme durable spécialement préparée que l'on extrude et que l'on vulcanise entre deux couronnes, d'acier ou d'autre métal, montées entre une jante de roue de véhicule routier et l'ensemble moyeu. L'invention peut se poser sur une roue neuve ou faire l'objet d'une modification d'une roue existante.
