Abstract

L’invention concerne un dispositif de freinage (1) qui comporte un disque de frein du type bi-matière et un étrier de frein (3), le disque de frein comportant une première partie (21) qui forme un bol et une seconde partie (22) surmoulée autour du bol (21), avec deux parties de surmoulage (221) de la seconde partie (22) qui recouvrent un bord périphérique (211) du bol (21), la seconde partie (22) du disque de frein comportant sur chaque face une piste de freinage (222) adaptée pour freiner la rotation du disque de frein par friction contre des plaquettes de frein (31) de l’étrier de frein (3), l’épaisseur de chacune des deux parties de surmoulage (221) étant d’au moins 4 mm et la surface de friction sur la piste de freinage (222) des deux plaquettes de frein (31) recouvre au moins en partie lesdites parties de surmoulage (221). Fig. 1The invention relates to a braking device (1) which comprises a brake disc of the bi-material type and a brake caliper (3), the brake disc comprising a first part (21) which forms a bowl and a second part (22) overmolded around the bowl (21), with two overmolding parts (221) of the second part (22) which cover a peripheral edge (211) of the bowl (21), the second part (22) of the brake disc comprising on each face a braking track (222) adapted to brake the rotation of the brake disc by friction against brake pads (31) of the brake caliper (3), the thickness of each of the two overmolding parts (221) being at least 4 mm and the friction surface on the braking track (222) of the two brake pads (31) covers at least partly said overmolding parts (221).
