Ventilated disk braking band for a disk brake

摘要

A braking band of a disc for a disc brake of the ventilated type extends between an inner diameter (D1) close to an axis of rotation of the disc and an outer diameter (D2) away from the said axis of rotation of the disc. The braking band comprises two leaves defining an intermediate space and joined by connection means. The ratio between the outer diameter of the surface (D2) and the thickness or maximum dimension of the said intermediate space (22) between the two leaves measured in a direction parallel to the axis of the disc lies between 15 and 32.
