Patent ID: 8220600

Claim:
Internally ventilated disc brake, comprising: a brake disc having two friction rings only spaced apart by ribs, a plurality of air cooling channels formed between the ribs and at least one heat dissipating element arranged between the friction rings wherein the two friction rings and the heat dissipating element comprise an integral molding so that the at least one heat dissipating element is cast into the molding in at least several areas, the at least one heat dissipating element projects into at least one of the brake disc cooling air channels in at least several areas, the at least one heat dissipating element is disposed substantially in a parting plane of the molding, said parting plane running parallel to the friction rings, the at least one heat dissipating element is configured as a double walled component formed of two main ribs and a plurality of cross struts disposed between the two main ribs, the heat dissipating element having an annular ring cross sectional shape configured substantially as a disc-shaped and/or plate-shaped component, the heat dissipating element running in the parting plane spaced from inner walls of the friction rings.
