Abstract
The invention relates to a brake disk comprising two friction rings which are connected via links and between which an air channel is configured, as well as support elements which are molded to the inner peripheral area of the brake disk and designed for engaging cams of a hub of an axle of a (utility) vehicle. In the inner peripheral area of the brake disk, the support elements bridge the air channel in the manner of links and axially protrude into the area of the friction rings to such an extent that the outer surfaces of the friction rings are situated at an axial distance from the outer surfaces of the support elements even in the maximum permissible state of wear. Openings in the axle hub and the brake disk ensure sufficient cooling.
