A brake disc for a disc brake of a motor vehicle includes a pot-shaped carrier part; a friction ring, and multiple connecting elements distributed in circumferential direction of the disc brake extending in radial direction, and configured as separate components, wherein the carrier part and the friction ring are fixedly interconnected in radial direction via the multiple connecting elements, wherein the connecting elements are form fittingly connected with the carrier part and with the friction ring.

Brake disc for a disc brake of a motor vehicle

The invention relates to a method for producing a brake disk (B) that comprises a supporting part () and a friction ring (R). The inventive method involves the following working steps: manufacturing, especially by casting, the supporting part () with at least one radially protruding projection () situated on the periphery of the supporting part; forming a cast core (), which is made of core sand and which surrounds the projection () over a foot section () that is assigned to the supporting part (), onto the supporting part () while sealing a free end section () of the projection () so that this end section () is not made wet by the sand of the cast core (); casting the friction ring (R) onto the supporting part (), which is provided with the cast core (), while casting around the free end section () of the projection (). The inventive method enables the production of brake disks, which are additionally optimized with regard to their function, with a supporting part and friction ring that are cast at different times. The invention also relates to a core forming tool, which is particularly suited for carrying out the inventive method.
