Abstract

L'invention concerne une structure de circlip de bloc de frein fractionné dans un ensemble étrier de frein flottant. La section transversale de la structure de circlip de bloc de frein est en forme de "己", et la partie inférieure de celle-ci est pourvue d'une structure de retour active. La structure de retour active est principalement composée de première et deuxième portions élastiques, d'une portion de liaison de structure de retour ayant une fonction de support, et d'un crochet incurvé destiné à tirer un bloc de frein qui sont agencés et connectés l'un après l'autre. La première portion élastique est pliée en forme de U et se trouve au niveau de la racine, et la deuxième portion élastique est une structure courbée en forme d'arc. La structure de circlip de bloc de frein comprend une structure saillante supérieure et une portion de liaison de corps de circlip inférieure, et la structure de retour active est disposée au niveau de la portion de liaison de corps de circlip. Sous la traction de la structure de retour active, la présente invention se sépare rapidement d'une surface d'un disque de frein pour réduire la pression de contact du disque, ce qui permet de réduire la résistance au roulement, d'améliorer la consommation d'énergie de l'ensemble du véhicule, et d'atténuer le bruit de cliquetis généré par le cognement du disque.
