Abstract

L'invention se rapporte à un dispositif d'écrou pour un mécanisme vis-écrou destiné à appliquer un effort axial de serrage sur un piston de frein (50) à partir d'un entraînement rotatif, au sein d'un d'actionneur motorisé. Le dispositif d'écrou comprend un fil métallique (20) comprenant une portion enroulée (21) de sorte qu'elle forme un enroulement hélicoïdal apte à être enroulé autour d'un arbre fileté d'actionnement (40). Le fil métallique comprend une portion d'arrêt en rotation (25) du fil qui dépasse radialement autour dudit enroulement (21) de façon à coopérer par engagement de formes avec un logement (52) du piston pour arrêter la rotation dudit enroulement. Le dispositif d'écrou comprend un manchon d'actionnement (30) entourant la portion enroulée (21) qui est insérée dans une rainure hélicoïdale dudit manchon. Le manchon comprend une face d'appui axial pour appuyer au moins en fonctionnement sur une face arrière d'appui du piston de frein. Le domaine de l'invention est celui des systèmes de freinage pour automobiles.The invention relates to a nut device for a screw-nut mechanism intended to apply an axial clamping force on a brake piston (50) from a rotary drive, within a motorized actuator . The nut device comprises a metal wire (20) comprising a wound portion (21) so that it forms a helical winding capable of being wound around a threaded actuating shaft (40). The metal wire comprises a portion of rotation stop (25) of the wire which protrudes radially around said winding (21) so as to cooperate by engagement of shapes with a housing (52) of the piston to stop the rotation of said winding. The nut device includes an actuating sleeve (30) surrounding the coiled portion (21) which is inserted into a helical groove of said sleeve. The sleeve includes an axial bearing face for pressing at least in operation on a rear bearing face of the brake piston. The field of the invention is that of automobile braking systems.
