Abstract

Ensemble d'une roue (1) et d'un pneumatique (2) sans chambre pour véhicule automobile, prévu pour fournir une indication d'usure du pneumatique. Le pneumatique (2) comporte au moins un élément optique (4), conducteur de rayonnement lumineux, traversant la bande de roulement (3) et la paroi (B) du pneumatique, et propre ô introduire dans le volume intérieur du pneumatique un flux lumineux dépendant de l'usure du pneumatique ; un détecteur (11) de rayonnement lumineux est installé dans le volume intérieur du pneumatique et est propre ô émettre un signal indicateur de l'usure en réponse au flux lumineux.
