Abstract
A brake disk for a disk brake, which consists of a brake disk chamber and at least one friction ring connected to the brake disk chamber by rivets, wherein a jacket of the brake disk chamber is provided with sections having reduced wall thickness and/or through-holes, which are axially directed material cut-outs located on the outer periphery of the brake disk chamber jacket, which material cut-outs are used to at least partially place the axially directed rivets. The friction ring and the brake disk chamber are centered with respect to each other exclusively by the rivets. The friction ring has at least one fastening extension directed inward from the friction surface, to which fastening extension a collar of the brake disk chamber jacket is connected by the rivets in that the side of the friction ring directed toward the brake disk chamber has an axially directed depression for accommodating the collar of the brake disk chamber, which depression is designed in such a way that there is radial play between the brake disk chamber and the friction ring.
