<p>A braking band (14) for use in disk-brake disks (10), comprises two plates (16, 18) coaxial with an axis (Z-Z), facing one another. The plates (16, 18) having facing surfaces (22) from which pillar-like elements (24, 26, 28) extend, transversely, to connect the plates, the pillar-like elements being distributed in circular rings or rows concentric with the plates so as to be distributed uniformly in the space (20), those pillar-like elements (24, 26) which are disposed in inside rows of the braking band (14) having rhombic cross-sections. The rhombic cross-sections of the pillar-like elements which are in inside rows of the band are symmetrical with respect to an axis transverse the direction of flow.</p> |
