Abstract

Lesdits freins à disque actionnés électriquement (10, 210) peuvent comprendre un mécanisme à vis et à écrou de grande efficacité (60) et/ou un mécanisme d'embrayage unidirectionnel (230). Le mécanisme à vis et à écrou de grande efficacité (60) comporte une vis (86) dont le filet de vis (89) a un pas prédéterminé, et au moins un écrou (77, 97) disposé autour de la vis (86) et ayant une ouverture intérieure (78, 98) avec un filet d'écrou (79, 99) à l'intérieur. Le pas du filet d'écrou (79, 99) est semblable au pas du filet de vis (89) et le diamètre du pas du filet d'écrou (79, 99) est supérieur au diamètre du pas du filet de vis (89). La vis (86) est entraînée par le moteur électrique (40) du frein à disque (10, 210). Le mécanisme d'embrayage unidirectionnel (230) comprend un élément d'entraînement à roue solaire (252) qui présente des fentes d'entraînement radiales (257) disposées face à face, à travers lesquelles s'étend une broche (243), laquelle s'étend transversalement à l'arbre d'entraînement (241) du moteur électrique (240). L'élément d'entraînement à roue solaire (252) est tourillonné à l'intérieur d'un élément à cage (281), qui présente des fentes de cage radiales disposées face à face (282) à l'intérieur desquelles s'étend la broche d'entraînement (243). Les fentes de cage radiales (282) se trouvent en non-alignement circonférentiel par rapport aux fentes d'entraînement radiales (257) de l'élément d'entraînement à roue solaire (252). L'élément d'entraînement à roue solaire (252) comporte des surfaces de came (253) recevant des roulements à rouleaux (290), lesquelles s'étendent à travers des ouvertures disposées face à face (284) ménagées dans l'élément de cage (281) pour se placer en prise avec une surface intérieure (297) d'un logement annulaire (295). Le mécanisme d'embrayage (230) permet à l'élément d'entraînement à roue solaire (252) d'être entraîné en rotation dans les deux directions par l'arbre d'entraînement (241), mais lorsque les forces de réaction tentent d'inverser la rotation de l'élément d'entraînement (252) et du moteur électrique (240), le mécanisme d'embrayage (230) se bloque et empêche une telle inversion de la rotation.
