Abstract
A brake disk with a friction ring () and a linking element () which are interconnected by a threaded fastener arrangement (). The threaded fastener arrangement ()encompasses a screw, a nut, and an intermediate element (). The intermediate element () prevents direct contact between the friction ring () and the linking element (). Also provided is a sleeve element () that is disposed on a shaft () of the screw (). A sliding block () is plugged onto the sleeve element (). The intermediate element ()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 () and the intermediate element (). The intermediate element also has a springy effect in an axial direction, whereby mechanical and thermal stresses can be compensated in the axial direction.
