A braking band extends between an inner diameter and an outer diameter. The braking band has two plates having inner surfaces delimiting a gap, outer surfaces having opposite flat circumferential portions and a plate body having an extension in axial direction. The plates are joined by connecting elements. At least one plate has at least one projection projecting into the gap without reaching the opposite plate, forming a localized narrowing of the gap and a thickening of the plate body, creating a localized increase of the thickness of plate. The projection extends from a first connecting element to an adjacent connecting element, connecting them, and along the circumferential direction, connecting at least two adjacent connecting elements. A group of projections extends circumferentially along a discontinuous annular path, avoiding a uniform distribution in circumferential direction.

Braking band of a disc for a disc brake of the ventilated type

A ventilated braking band for brake disc having a first plate and a second plate; the first plate has at least a first inner surface, and the second plate has a second inner surface. The first inner surface defines a first inner surface plane or level (z-z) coinciding with said first inner surface, and the said second inner surface defines a second inner surface plane or level (z-z) coinciding with the second inner surface. The ventilated braking band has connecting elements which extend in an axial direction between the first inner surface and the second inner surface. The ventilated braking band has at least one bulge. The at least one bulge is partially interpenetrated with: at least one portion of the first foot, thus forming a structural continuity with the first foot, thus avoiding the first inner surface level from being reached; or at least one portion of a second foot, thus forming a structural continuity with the second foot, thus avoiding the second inner surface level from being reached.

Ventilated braking band, assembly of ventilated brake disc and method of ventilation

A ventilated braking band for ventilated brake disc, unusually capable of an efficient cooling and structural resistance, has a first plate and a second plate. The ventilated braking band has protrusions which project from a plate without reaching the other plate. Some of the protrusions which project from one of the first or second plate form a protrusion group. The protrusion group forms a continuous or interrupted protrusion group path. The protrusion group projects from both plates, thus forming at least a first and a second protrusion group path. The projections of the first and second protrusion group path cross one another on a plane parallel to the first or second braking surface of the respective plates.
