<p>A disk-brake disk comprising a bell (2) and an annular braking band (3) connected coaxially to the bell by means of coupling elements (4), in which the braking band (3) has an inner cylindrical surface facing an outer cylindrical surface of the bell (2). To form a simple and reliable coupling between the bell and the braking band (2), the latter has radial recesses (10) which extend from its inner cylindrical surface, the bell (2) has a plurality of peripheral openings (9; 9') in its outer cylindrical surface, and the coupling elements (4) have portions (4a; 4b) which engage the peripheral openings of the bell (2) and the radial recesses (10) of the braking band (3).</p> |
