Abstract

Dispositif de serrage D pour système de freinage 2 comportant : - un actionneur électrique 10 destiné à fournir une force de serrage, - un organe d’application de force de serrage 7 à au moins un élément de friction, et - des moyens 11, du type à vis à billes, de conversion du mouvement de rotation d’un arbre de sortie 10A de l’actionneur électrique 10 en mouvement de translation de l’organe d’application de force de serrage 7, les moyens de conversion 11 comportant un écrou 12, recevant le mouvement de rotation de l’arbre de sortie 10A de l’actionneur 10 pour le transmettre à une vis 14 en mouvement de translation entre une position de repos n’appliquant pas de force de serrage et une position d’application de force de serrage, caractérisé en ce qu’il comporte en outre un organe 22 pour le rappel élastique de la vis 14 en position de repos, cet organe 22 comportant une première extrémité 2, liée en translation à la vis 14, et une seconde extrémité 26, fixe par rapport au mouvement de translation de la vis 14. Figure pour l’abrégé : figure 3Clamping device D for braking system 2 comprising: - an electric actuator 10 intended to provide a clamping force, - a clamping force application member 7 to at least one friction element, and - means 11, of ball screw type, for converting the rotational movement of an output shaft 10A of the electric actuator 10 into translational movement of the clamping force application member 7, the conversion means 11 comprising a nut 12, receiving the rotational movement of the output shaft 10A of the actuator 10 to transmit it to a screw 14 in translation movement between a rest position not applying clamping force and a position of application of tightening force, characterized in that it further comprises a member 22 for the elastic return of the screw 14 to the rest position, this member 22 comprising a first end 2, linked in translation to the screw 14, and a second end 26, fixed relative to the translational movement of the screw 14.
