The invention relates to a brake disk comprising a friction ring ( 2 ) and a linking element ( 4 ) which are interconnected by means of a screwing arrangement ( 6 ). The screwing arrangement ( 6 ) encompasses a screw, a nut, and an intermediate element ( 12 ). Said intermediate element ( 12 ) prevents direct contact between the friction ring ( 2 ) and the linking element ( 4 ). Also provided is a sleeve element ( 14 ) that is disposed on a shaft ( 16 ) of the screw ( 8 ). A sliding block ( 18 ) is plugged onto the sleeve element ( 14 ). The intermediate element ( 12 ) at least partly encloses the sliding block such that thermal expansions acting in a radial direction can be compensated by a relative movement between the sliding block ( 18 ) and the intermediate element ( 12 ). The intermediate element also has a springy effect in an axial direction, by means of which mechanical and thermal stresses can be compensated in said axial direction.
