Abstract

L'invention concerne une fixation de plaquette de frein pour un frein à disque, en particulier pour des véhicules utilitaires. Des deux côtés d'un disque de frein, des plaquettes de frein associées (2) sont respectivement montées de manière contrainte par ressort dans un compartiment de garniture d'une flasque de frein stationnaire, lesquelles présentent respectivement un ressort de retenue de garniture (6) réalisé avec une forme courbe, lesquelles sont maintenues de manière à ne pas être perdues et à pouvoir se déformer radialement sur une plaquette de support de garniture (5) portant une garniture de friction (4) d'une plaquette de frein (2), ce qui entraîne l'éloignement radial de l'axe du disque de frein et le rapprochement contre un étrier de retenue de garniture (3) maintenu dans un étrier de frein (1). La fixation de plaquette de frein est réalisée de manière à ce que le ressort de retenue de garniture (6) soit formé par un fil de fer, courbé de manière ondulée et réalisé en forme de ruban sur ses extrémités.
