Abstract

Dispositif de détection de crevaison de pneumatique de véhicule, utilisé pour détecter un signal de crevaison de pneumatique, le dispositif de détection comprenant : une source (2) de signaux et un élément de détection (3). La source (2) de signaux est montée dans la cavité intérieure ou sur l’extérieur de la paroi de cavité du pneumatique (1). L’élément de détection (3) est monté sur le support d’une roue (12) en vue de détecter le signal provenant de la source (2) de signaux, lequel signal est ensuite transmis par fil à une unité de commande centrale (4). Si la pression du pneumatique est normale, la source (2) de signaux occupe une première position. En cas de crevaison, la déformation du pneumatique (1) fait s’écarter la source (2) de signaux de la première position jusqu’à une deuxième position ce qui permet à l’élément de détection (3) de détecter la variation du signal provenant de la source (2) de signaux.
