Abstract

La présente invention concerne un frein à disque, notamment pour un véhicule utilitaire, présentant un étrier de frein (2) qui comprend un disque de frein (1) et qui est fixé sur la flasque de frein (7) par deux éléments de fixation (5, 6) de manière à pouvoir se déplacer en direction axiale par rapport au disque de frein (1). Un élément de fixation (6) est conçu sous forme de palier fixe et l'autre (5) est conçu sous forme de palier libre qui présente une douille de guidage (8) montée dans l'étrier de frein (2). Un longeron de guidage (10) fixement relié à la flasque de frein (7) peut se déplacer en direction axiale dans cette douille de guidage. Au moins une zone partielle de la douille de guidage (8) est formée par une bague de glissement (11) qui entoure le longeron de guidage (10). Un ressort (12) se trouvant sur la périphérie extérieure de la bague de glissement s'appuie sur un composant de l'étrier de frein (2). Le frein à disque selon cette invention est caractérisé en ce que le ressort (12) est constitué d'un arceau (18) entourant au moins partiellement la bague de glissement (11) et de pattes adjacentes (19) qui s'étendent dans la direction de l'axe longitudinal de la bague de glissement (11) et qui se trouvent au moins par endroits sur la bague de glissement (11) et sur le composant de l'étrier de frein (2).
