<p>The present invention relates to a brake disk for a disk brake, which is intended particularly for use in motor vehicles, comprising a friction ring (2) as the first connecting part and a carrier part (3) as the second connecting part, wherein the connecting parts (2, 3) are rotatably fixed to each other by radially oriented projections (10), which are integrally formed as one piece on one of the connecting parts (2, 3) and positively engage in correspondingly shaped recesses (19) of the other connecting part (2, 3). The brake disk (1) according to the invention can be produced cost-effectively, guarantees high operating reliability, and at the same time exhibits optimized behavior under the influence of the heat that inevitably develops during a braking operation. This is achieved in that at least one of the projections has a through-channel (12) and that in the friction ring (2) at least one ventilation channel (7) for removing ambient air from, or for feeding ambient air to, the through-channel (12) of the respective projection (10).</p> |
