The subject of the invention is a one-piece brake disc for rolling stock with improved hub mounting, namely two brake plates are mounted to a hub via flexible brackets. The brake disc (1) consists of two coaxial brake plates (2) which are interconnected by cooling ribs (7), a hub (3) and flexible brackets (4) that are equidistantly arranged circumferentially on an outer circumference (3a) of the hub (3), the brake plates (2) being inseparably fastened to the hub (3) via the flexible brackets (4). The bracket (4) is formed of a rigid portion (4a), with which the bracket (4) is inseparably attached to the outer circumference (3a) of the hub (3), and of a flexible portion (4b) which continues from the rigid portion (4a), the flexible portion (4b) being made at a certain inclination with respect to axis of rotation, and the flexible portion (4b) is provided at the point of attachment to the brake plate (2) with an attachment point (5), with which it is inseparably attached to both brake plates (2) via a cast connection (6). By attaching the brake plate (2) to the hub (3) via flexible brackets (4), a free thermal expansion of the brake plates (2) in the radial direction is enabled, thus significantly reducing the stresses on the brackets (4) caused by thermal deformations that occur during braking operation of rolling stock.
