DISC FOR DISC BRAKES AND PROCESS FOR MANUFACTURING THE SAME

摘要

Disc for disc brakes comprising a metallic bell (2) and a radially external band (3) in composite material comprising carbon fibers. The bell (2) is co-casted on the radially external band (3). The radially external band (3) presents side braking surfaces (4) suitable to cooperate with brake calipers to exert a braking action on a vehicle. The radially external band (3) is shaped to form a plurality of protrusions (8) of composite material, which protrusions (8) are placed around a symmetry axis. In a radial plane, a terminal portion (20) of each protrusion (8) juts radially inwards and tapers towards the symmetry axis and the co-casted bell (2) incorporates the terminal portions (20).
