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.

Braking band, a ventilated disk-brake disk, and a core box for the production of a disk-brake disk core

A braking band for a disk-brake disk which is capable of exceptionally quiet braking comprises at least two plates connected to one another by connecting elements, in which the space between the plates forms an internal air-duct for the cooling of the braking band. At least one of the plates has, in one of its surfaces defining the air-ducts, at least one groove which extends along at least a portion of an orbit around the axis of symmetry of the disk and the cross-section of which becomes wider towards the air-duct.

Braking band for a brake disk

The invention relates to a method and tools for producing a braking band () of a disk-brake disk () by casting, in which the disk comprises at least two plates (') connected to one another by connecting elements () forming an internal air-duct () for the cooling of the braking band (). With the method and the tools, a disk is produced in which at least one of the plates (&#x2032;) has, in its surface (&#x2032;) defining the air-ducts (), at least one groove (&#x2032;) having a cross-section which becomes wider towards the air-duct.
