The invention relates to an axle-mounted brake disk for a rail vehicle, comprising two friction rings which are arranged in parallel and at a distance from each other and are interconnected by a plurality of ribs extending in the direction of the rotational axis of the friction rings, where at least some of the ribs are embodied with different cross-sections from each other, where the cross-sections of a first subset of the ribs, embodied as supporting elements transmitting pressure forces, do not fall below a minimum cross-section, defined by the stability required in relation to the mechanical load during a brake process, and the cross-section of a second subset of the ribs, used to radiate thermal energy, falls below the minimum cross-section.
