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.
