Abstract

A brake disk includes a friction ring, a brake disk hat and a securing ring. The friction ring has an inner side, on which a plurality of projections and intermediate spaces for connecting the friction ring to the brake disk hat are disposed. The brake disk hat has, on its outer side, intermediate spaces and projections which correspond with the projections and intermediate spaces of the friction ring and are shaped to engage in a positively locking manner into the projections and intermediate spaces of the friction ring, with the result that the friction ring is connected fixedly to the brake disk hat so as to rotate therewith. The securing ring secures the friction ring on the brake disk hat in the axial direction. The securing ring includes a number of spring elements which are spaced apart from one another in the circumferential direction of the securing ring.
