Patent attributes
The disk includes a bell (2), an annular braking band (3) and coupling (11, 12, 13) between bell and band. The bell (2) is provided with a plurality of openings (6) along its periphery, the band (3) is provided in the vicinity of its inner edge with a corresponding plurality of slots (9) having parallel sides in the radial direction, while the coupling includes a plurality of dragging elements (11), each of which engages with an opening (6) of the bell and a slot (9) of the band to create a tangential constraint between bell (2) and band (3). In order to reduce the specific pressure between the dragging elements (11) and the slots (9), each of the dragging elements (11) includes a part (16) with two parallel opposite faces (20) that engage with the parallel sides of the slot (9) in such a manner as to be in contact with them.
