Abstract: A brake disk for a disk brake includes a friction ring as first connection partner and a carrier part as second connection partner, wherein the connection partners are connected to one another for co-rotation by radially-oriented projections, which are formed as single pieces onto one of the connection partners and engage in positive fit in correspondingly shaped cut-out apertures of the respective other connection partner. The brake disk according to the invention can be manufactured cheaply, guarantees high operational reliability, and at the same time has optimized behavior under the influence of the heat which is unavoidably generated during a braking procedure. This is achieved in that at least one of the projections has a passage channel, and in that at least one ventilation channel is formed in the friction ring for conducting away ambient air or for introducing ambient air into the passage channel of the individual projection.

Abstract: The invention relates to a method for producing a brake disk (B) that comprises a supporting part (2) and a friction ring (R). The inventive method involves the following working steps: manufacturing, especially by casting, the supporting part (2) with at least one radially protruding projection (10) situated on the periphery of the supporting part; forming a cast core (14), which is made of core sand and which surrounds the projection (10) over a foot section (10a) that is assigned to the supporting part (2), onto the supporting part (2) while sealing a free end section (10b) of the projection (10) so that this end section (10b) is not made wet by the sand of the cast core (14); casting the friction ring (R) onto the supporting part (2), which is provided with the cast core (14), while casting around the free end section (10b) of the projection (10).
