Patent ID: 8474580

Claim:
A floating brake disc comprising: an outer ring having a brake band; and an inner ring via which the floating brake disc is to be connected to a wheel of a vehicle, wherein: said outer ring and said inner ring have a number of contact regions between the outer ring and the inner ring; the contact region is formed on a circular arc extending between the outer ring and the inner ring such that said contact region follows said circular arc; the contact regions are arranged concentrically with the floating brake disc; the outer ring and the inner ring are connected to one another in the contact regions; the contact regions have at least one connecting means, in particular a rivet; the outer ring has an indentation; and next to the at least one contact region the inner ring has a projection which engages in said indentation in the outer ring in such a way that a bearing surface between the inner ring and the outer ring is formed, at least at times when the brake disc is in operation in said vehicle; wherein there is a clearance between the projection and the indentation, the clearance being formed such that there is no substantial contact between the projection and the indentation until the bearing surface is formed by a relative movement, during a braking operation, between the inner ring and the outer ring and wherein during an unbraked operation of the vehicle the bearing surface is not formed and substantially all force transmitted to the outer ring from the inner ring is transferred via the at least one connecting mean.
