<p>The invention relates to a brake disk for railway rolling equipment intended to be secured to a wheel to be braked and to engage, during braking, with a composite material lining that is mounted onto a movable jaw and capable of being placed in contact with the disk via a control means. The brake disk is characterized in that the disk is divided into three identical parts that each comprise, on the inner surface (6) thereof opposite the braking surface, stiffening elements made of ribs (8) that are regularly directed in a radial direction and a concentric direction at the same time relative to the axis of the wheel so as to control the changes in the shape of said disk due to the braking heat.</p> |
