The invention relates to a brake disc comprising a support bell, intended for being connected to a wheel hub of a vehicle, and a braking band intended for cooperating with a caliper arranged astride of the brake disc. The braking band comprises two flanges connected by a plurality of connecting elements that define ventilation channels. The brake disc is characterized in that it comprises driving elements between the braking band and the bell, which elements improve the efficiency of the ventilation inside the braking band, as well as the mechanical deformation of the brake disc during the braking step. |
