Abstract
In a composite disc for heavy-vehicle disc brakes, an annular braking band comprises at least two portions which are divided along at least one axial separation plane defining, on these portions, respective pairs of flat surfaces which can be arranged face to face in pairs. Radially-oriented, calibrated, semicylindrical cavities are formed in the flat coupling surfaces in order to define cylindrical seats for housing corresponding calibrated locating pins after the assembly of the portions of the band. This solution ensures precise axial alignment between the braking surfaces of the portions of the band.

A composite disc-brake disc comprising:
- a hub;
- and
- an annular braking band, said band comprising at least a first portion and a second portion,
- wherein said first portion and said second portion are divided along at least one axial separation plane such that respective pairs of flat surfaces are defined on the first and second portions and which can be arranged face to face in pairs in order to assemble the band,
- wherein the respective pairs of flat surfaces include respective cavities extending radially which define cylindrical seats extending radially when said first portion and said second portion are fixed together, said cylindrical seats house corresponding locating pins, and
- wherein said first portion and said second portion are fixed together by means of tangentially-oriented, threaded connecting members.
