Abstract: A disc assembly for a disc brake and energizing ring, or flywheel includes a disc brake disc, a braking band, a bell connecting the brake disc to a vehicle hub; and a connecting portion between the braking band and the bell. An energizing ring includes an energizing ring body having an energizing side, opposite the disc, and coupling side, facing the disc. An energizing ring connecting portion connects cantilevered to the bell to avoid interfering with the braking band and forms an end surface parallel to the radial direction. Projections and/or recesses are provided in the energizing side. A coupling portion cantilevers from the energizing ring body axially and includes a free end portion. The free end portion is received in the energizing ring connecting portion passing through the radial end surface. The energizing ring connecting portion closely surrounds the free end portion, leaving the energizing ring body free.
