Some pin elements may have a substantially circular cross section, forming a circumference-shaped edge. Other pin elements may have a substantially rhomboidal cross section, forming a symmetric rhombus-shaped edge with respect to a radial direction and a circumferential direction orthogonal to this radial direction. Yet other pin elements may have a substantially circular cross section, forming a circumference-shaped edge.

Braking band of a disc for disc brake of ventilated type

Brake band () of a disc for a ventilated disc brake, unusually capable of reducing braking whistling, extends between an inner diameter (D), close to a rotation axis (X-X) of the brake band (), and an outer diameter (D), far from said rotation axis (X-X) of the disc, said brake band () comprising two plates () facing one another and defining a gap (), comprising two plates () being joined together by heat dissipation and connection means or elements (), said connection means () being shaped like small columns that project from one plate towards the opposite plate in the form of pins () remaining inside said gap (), said pins () being grouped in at least two rows or tiers () arranged circumferentially. Some of the pins () arranged in said second tier (or) having a section shaped like a rhombus or diamond with four vertices joined by four sides in which said sides defining said section are substantially rectilinear in shape.

Brake band for a ventilated disc brake

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.
