Brake disc mounting.

摘要

An improved mounting structure (10) for mounting a brake disc (12) to a hub member (14) for rotation therewith and a degree of axial (22) and radial (24) freedom relative thereto is provided. The hub is provided with an array of internally threaded bores (26) and the disc (12) is provided with a radially inwardly extending flange (30) having a plurality of radially elongated slots (32) alignable with said internally threaded bores. Threaded fastener members, such as studs (46) are threadably received within the internally threaded bores (26) and extend through the radially elongated slots (32) and include a rotatable bearing member (50) on the other end thereof. A generally tubular spacer (38) having an axial length (40) greater than the axial thickness (42) of the disc flange (30) surrounds the shanks of the externally threaded stud (46). One end of the spacer bears against the hub member and the other end (54) of the spacer is engagable by the rotatable bearing member bears directly or indirectly solely against the spacer. A resilient thrust washer such as a Belleville washer (52) may be interposed the rotatable bearing member (50) and the flange (30) to provide a resilient axial force tending to urge the disc (12) axially toward the hub (14).
