Abstract

Une coupelle inférieure monobloc (14) de butée de suspension (10), destinée à être interposée entre une extrémité supérieure d'un ressort hélicoïdal et un appui supérieur (12), présente une face inférieure (40) formant un épaulement d'appui axial (42) pour l'extrémité supérieure du ressort hélicoïdal, qui comporte une butée d'indexation (46) s'étendant dans un plan axial, pour une indexation angulaire de l'extrémité supérieure du ressort hélicoïdal par rapport à la coupelle inférieure monobloc (14) d'un axe de révolution (100) de la butée de suspension. La coupelle inférieure monobloc (14) comporte un renfort de rigidification différentiée (50, 150, 250) conférant à la coupelle inférieure monobloc (14) une raideur en compression axiale dont la valeur est supérieure à un seuil donné en tout point de l'épaulement d'appui axial (42) situé dans une première zone angulaire (A) autour de l'axe de révolution (100) englobant la butée d'indexation (46), et est inférieure audit seuil donné en tout point de l'épaulement d'appui axial (42) situé dans une deuxième zone angulaire autour de l'axe de révolution (100).A one-piece lower cup (14) for the suspension stop (10), intended to be interposed between an upper end of a helical spring and an upper support (12), has a lower face (40) forming an axial support shoulder (42) for the upper end of the coil spring, which has an indexing stop (46) extending in an axial plane, for angular indexing of the upper end of the coil spring relative to the one-piece lower cup ( 14) of an axis of revolution (100) of the suspension stop. The one-piece lower cup (14) comprises a differentiated stiffening reinforcement (50, 150, 250) giving the one-piece lower cup (14) a stiffness in axial compression whose value is greater than a given threshold at any point of the shoulder. axial bearing (42) located in a first angular zone (A) around the axis of revolution (100) including the indexing stop (46), and is below said given threshold at any point of the shoulder d 'axial support (42) located in a second angular zone around the axis of revolution (100).
