Abstract

L’invention se rapporte à un dispositif (7) de serrage pour système (1) de freinage destiné à exercer un déplacement relatif entre des éléments de friction et comportant un bâti (8) supportant un actionneur (12) électrique destiné à fournir la force de serrage et un mécanisme (15) de conversion du mouvement de rotation d’un arbre (13) de sortie de l’actionneur (12) électrique en mouvement de translation qui est couplé à l’actionneur (12) électrique afin de permettre le mouvement de déplacement relatif entre les éléments de friction selon une direction rectiligne axiale (A). Selon l'invention, le mécanisme (15) de conversion est du type à vis à billes et le dispositif (7) de serrage comporte au moins un élément (19a, 19b) de guidage radial et/ou tangentiel de la vis (17) du mécanisme (15) de conversion afin d’améliorer la résistance mécanique de ce dernier.
