Abstract: The invention relates to a brake disc for a rail vehicle, with which a hub body (16) and a brake ring (12) are connected to one another such that with braking procedures a thermal expansion of the brake ring (12) relative to the hub body (16) is possible. At the same time screws (15) pass through axially aligned openings in a hub flange (14) arranged on the hub body (16) and a brake ring flange (13) arranged on the brake ring (12). According to the invention the screws at their end exiting the brake ring flange (13), by way of a retaining element which, for example, may be a retaining lug (17) formed integrally on the hub body (16) or a retaining bracket fixed on the hub body, may be fixed relative to the hub body (16) so that an axially parallel position of the screws (15) and a centering of the brake ring (12) is ensured even with thermal expansions.
