  • Patent number: 8596429
    Abstract: The invention relates to a brake disk comprising a ceramic friction ring (4) and a connecting flange (6) that is disposed concentric to the friction ring (4). The friction ring (4) is provided with a fastening ring (8) in an interior area, which encompasses fastening bores (10). The friction ring (4) is joined to the connecting flange (6) at the fastening bores (10) by means of fixing means. The invention is characterized in that the friction ring (4) is provided with relief slots (12) between the fastening bores (10) in the fastening ring (8), said relief slots (12) radially extending from an interior area of the fastening ring (8) in the direction of a friction zone (20) of the friction ring (4).

  • Patent number: 7770699
    Abstract: 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.

  • Patent number: 7472777
    Abstract: The invention relates to a brake disk (2) comprising a friction ring (4) and a brake disk hub (6). Both the friction ring (4) and the brake disk hub (6) are provided with a ring land (8, 10) which overlap in a concentric manner. The ring land (8, 10) encompass recesses (14, 16) through which a joining arrangement (12) is guided in the form of a connecting pin (20). Also provided is a support ring (18) which encloses the ring land (8) of the friction ring (4) in a sandwich-type manner along with the ring land (10) of the brake disk hub (6). The support ring (18) comprises recesses (22) within which ends of the connecting pin (20) are supportingly mounted.
