Patent ID: 7770699

Claim:
A brake disk with a friction ring ( 2 ) made of a carbon fiber reinforced ceramic, a linking element ( 4 ) made from an aluminum alloy and a threaded fastener arrangement for the connection of linking element ( 4 ) and friction ring ( 2 ), in which the threaded fastener arrangement comprises at least one screw ( 8 ), a nut ( 10 ) and an intermediate element ( 12 ) which prevents a direct contact of the friction ring ( 2 ) and the linking element ( 4 ), wherein the intermediate element ( 12 ) is essentially U-shaped with two long sides ( 22 ), provides a resilient force between friction ring ( 2 ) and linking element ( 4 ) in the axial direction and features on its long sides ( 22 ) flaps ( 24 ) with resilient moldings ( 26 , 42 ) for the engagement with oblong recesses ( 20 ) of the linking element ( 4 ), the flaps ( 24 ) are bent such that they are positioned above boundaries ( 36 ) of the oblong recesses ( 20 ) of the linking element, thereby retaining the intermediate element ( 12 ) also in radial direction within these oblong recesses ( 20 ), a sliding block ( 18 ) is provided, the intermediate element ( 12 ) is arranged such that it at least partially encloses the sliding block ( 18 ) to compensate for a radial movement of the friction ring ( 2 ) and the linking element ( 4 ), and the friction ring ( 2 ) features an inner revolving retainer ring ( 21 ) with fixing holes ( 23 ).
