Abstract
Dispositif de freinage assisté. Un servomoteur pneumatique est associé à un amplificateur hydraulique. Le servomoteur comporte une paroi mobile avec un noyau comportant un alésage, à l'intérieur duquel est introduit une portion cylindrique d'un piston de l'amplificateur hydraulique. La portion cylindrique comporte une gorge annulaire de section ovale, à l'intérieur de laquelle sont positionnées deux pièces de serrage en forme d'étrier. Les pièces de serrage comportent des languettes qui pénètrent à l'intérieur d'encoches prévues dans l'alésage du noyau pour une position angulaire prédéterminée de la gorge de la portion cylindrique, de façon à solidariser cette dernière avec le noyau. Application aux systèmes de freinage.
