Patent ID: 7967115

Claim:
An internally ventilated brake disc, having at least one friction ring, which is connected to a brake-disc chamber via fastening elements and take up the friction ring so as to form an annular gap with respect to the brake-disc chamber, which has a cylindrical fastening section with several through-holes, so that, between an outer circumference of the fastening section and an inner circumference of the friction ring, the annular gap is formed, which is larger than a maximum change in the inner circumference of the friction ring and in the outer circumference of the fastening section that is afforded at least by thermal or mechanical load, characterized in that the friction ring is replaceably mounted to the brake-disc chamber by the fastening elements which take the form of threaded bolts, each having a cylindrical section and a threaded section, the threaded bolts being inserted into these through-holes of the brake-disc chamber from the inside of the brake-disc chamber toward the outside and being screwed into the brake-disc chamber in such a way that the cylindrical sections of the threaded bolts extend outward in the radial force direction over an outer circumference of the brake-disc chamber and that the cylindrical sections of the threaded bolts are guided with play in holding sections of the friction ring and that the threaded bolts are fastened in the through-holes of the brake-disc chamber.
