Abstract
A braking band with a remarkable capacity for improved cooling, for use in disk-brake disks, comprises two plates coaxial with an axis, facing one another, and spaced apart to form a space in which an air-flow takes place from the axis towards the outer side of the band, the plates having facing surfaces from which pillar-like elements 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, those pillar-like elements which are disposed in inside rows of the braking band 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 and each element for connection between the plates extends from one plate to the other whilst remaining within the space.
