Abstract

L’invention concerne un disque (1) de frein comportant des première et deuxième plaques (1a, 1b) annulaires séparées par un intervalle (9), la première plaque (1a) présentant un évidement central dans lequel pénètre un bol central (2) raccordé par une piste intérieure (3) à la deuxième plaque (1b), une couronne entourant le bol central (2) étant laissée libre dans l’évidement central, des ailettes (4) de ventilation s’étendant au moins partiellement dans l’intervalle (9). Une portion (4a) d’au moins une partie des ailettes (4) débouche dans la couronne en pointant vers le bol central (2) et en étant visible d’un extérieur du disque du frein à l’opposé de la deuxième plaque (1b) annulaire, ladite portion débouchante (4a) d’au moins une partie des ailettes (4) étant revêtue d’une peinture la différenciant d’une peinture au moins du bol central (2). FIGURE 1The invention relates to a brake disc (1) comprising first and second annular plates (1a, 1b) separated by a gap (9), the first plate (1a) having a central recess into which a central bowl (2) penetrates connected by an inner track (3) to the second plate (1b), a crown surrounding the central bowl (2) being left free in the central recess, ventilation fins (4) extending at least partially into the interval (9). A portion (4a) of at least part of the fins (4) opens out into the crown, pointing towards the central bowl (2) and being visible from outside the brake disc opposite the second plate ( 1b) annular, said opening portion (4a) of at least part of the fins (4) being coated with a paint differentiating it from a paint at least of the central bowl (2).
