Brake disc assembly with segments

A brake disc assembly comprising a central drive hub and a wear disc comprising first and second faces, the faces being held together axially around the hub, each face having a respective inner surface facing the inner surface of the other face, each face being formed of at least two distinct segments, each segment extending between two radial edges,

• the radial edges of the segments of one face not extending opposite the radial edges of the segments of the other face, each face segment being adapted to be secured to a segment of the other face via at least one fastening member adapted to hold said faces,
• wherein each face comprises the same predetermined number (n) of segments, each segment having an equal angular extent (α) for all segments of the face, and wherein the angular offset (θ) between segments of facing faces is substantially equal to the angular extent divided by the predetermined number of segments,
• wherein each segment comprises at least one fastening tab at the hub, each fastening tab defining a fastening through-hole between the inner surface and the outer surface,
• wherein each fastening tab has an inner surface and an outer surface, with the inner surface of one fastening tab facing an inner surface of a fastening tab of an opposite segment,
• the fastening holes of mating fastening tabs being aligned,
• the assembly comprising, for each pair of fastening holes mating with each other, a fastening device, the fastening device comprising a fastening sleeve provided with two opposite end portions, each suitable for being inserted respectively in one of the fastening holes.
