Connection of disk brake rotor to vehicle wheel hub

摘要

The invention relates to a disk brake unit for a vehicle wheel with a hub (30) having a rotational axis (28) and with a brake disk (20) which is slidable in the direction of the rotational axis (28) but solidly connected to the hub (30) both in circumferential and in radial direction, the hub (30) being provided on its external casing (36) for this purpose with outer dogs and the brake disk (20) having an internal casing (34) which is in contact with the external casing (36) and is provided with inner dogs. The brake disk (20) is provided with an outer ring (22) and with an inner ring (24), the inner ring (24) only forms the internal casing (34) with the inner dogs, the inner ring (24) and the outer ring (22) are non-rotatably linked together, the outer ring (22) only is provided with a friction ring, and means are provided which prevent heat from being transmitted from the friction ring to the internal casing (34), said means being arranged between friction ring and internal casing (34). <IMAGE>
