Abstract
A brake disk for a disk brake mounted on either the axle or wheel of a rail vehicle has on its inner peripheral portion a flange ring provided with parallel annular surfaces which are inclined to a central plane of the disk brake. These inclined surfaces are clamped between an inclined surface on a hub and an inclined surface on a retaining ring. The retainer ring is closely positioned upon the hub but in such a manner that any thermal expansion of the brake disk will enable the flange ring to move unhindered in an oblique radial outward direction while at the same time maintaining the brake disk locked and centered without overstressing the fastening bolts which pass through the hub portion and the retainer ring.
