A brake disk with a friction ring (2) and a linking element (4) which are interconnected by a threaded fastener arrangement (6). The threaded fastener arrangement (6)encompasses a screw, a nut, and an intermediate element (12). The 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, whereby mechanical and thermal stresses can be compensated in the axial direction.

We claim: 1. 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). 2. The brake disk according to claim 1, wherein the oblong recesses (20) extend in radial direction to retain the threaded fastener arrangement (6). 3. The brake disk according to claim 1, wherein the intermediate element (12) features a radial suspension (46) with respect to the linking element (4).
