  • Patent number: 7040466
    Abstract: The invention relates to a brake disc for a disc brake, in particular in motor vehicles. Said brake disc comprises a friction ring (12) and a pot-shaped supporting part (14), the friction ring consisting of several ring segments (18), which adjoin one another in a circumferential direction. To provide a construction that can be commercially produced in a cost-effective manner and that is not prone to warping, the ring segments are provided with semi-circular recesses (18a), which encompass retaining bolts (16) that extend radially. The retaining bolts are fixed in circumferential sections of the supporting part and support the ring segments by means of a positive fit in a centrifugal direction. The retaining bolts are preferably configured in a tubular manner.
