Abstract

Gaine destinée à assurer l'étanchéité entre le piston et le cylindre de commande d'un frein à disque pour les protéger de l'humidité et de la poussière. Cette gaine comprend une armature annulaire en métal à laquelle adhère un manchon monobloc en élastomère moulé dont la paroi comporte sept tronçons d'épaisseurs différentes ou variables, ce qui lui permet de se plisser dans l'intervalle annulaire compris entre le piston et le cylindre lorsque le premier s'enfonce dans le second, par exemple au cours du remplacement des patins du frein à disque. Application à la protection des freins à disque d'automobiles.Sheath intended to ensure the seal between the piston and the control cylinder of a disc brake to protect them from humidity and dust. This sheath comprises an annular metal frame to which adheres a one-piece molded elastomer sleeve, the wall of which comprises seven sections of different or variable thicknesses, which allows it to crease in the annular gap between the piston and the cylinder when the first sinks into the second, for example during the replacement of the disc brake pads. Application to the protection of automobile disc brakes.
