Abstract

The invention relates to a brake disc for a rail vehicle, with which a hub body ( ) and a brake ring ( ) are connected to one another such that with braking procedures a thermal expansion of the brake ring ( ) relative to the hub body ( ) is possible. At the same time screws ( ) pass through axially aligned openings in a hub flange ( ) arranged on the hub body ( ) and a brake ring flange ( ) arranged on the brake ring ( ). According to the invention the screws at their end exiting the brake ring flange ( ), by way of a retaining element which, for example, may be a retaining lug ( ) formed integrally on the hub body ( ) or a retaining bracket fixed on the hub body, may be fixed relative to the hub body ( ) so that an axially parallel position of the screws ( ) and a centering of the brake ring ( ) is ensured even with thermal expansions. The mounting of the screws ( ) is effected indirectly via an axially displaceably movable sleeve ( ) or by a retaining braket engaging into a groove on the hub. Furthermore there are provided radial guides for the brake ring ( ) which may be realised, for example, by the guiding of the sleeve ( ) in a slide block.
