Abstract

L'invention concerne les articulations élastiques et les procédés pour les établir. Ces articulations, plus spécialement destinées aux tourillons utilisés dans la suspension de véhicules, avec interposition d'un manchon en. matière plastique coopérant avec un manchon en matière élastomère, comme décrit dans le brevet principal, se caractérise par le fait que la matière plastique est choisie parmi celles qui sont susceptibles de se déformer à chaud pour permettre la formation des cannelures sur un noyau approprié, mais de s'opposer à la migration du soufre ou autres ingrédients de vulcanisation à partir du manchon extérieur en élastomère. En particulier, on choisit un polyamide ou encore une matière du genre Téflon. L'invention peut s'appliquer au cas où il s'agit d'un manchon en élastomère intérieur et d'un manchon en matière plastique extérieur. Application plus spécialement aux tourillons pour véhicules.
