WHEEL HUB AND BRAKE DISC ARRANGEMENT FOR HEAVY TRUCKS

摘要

Wheel hub and brake disc arrangement for a vehicle wheel. The wheel hub (6) has a region with sequential V-shaped ridges (10) and troughs (11). The brake disc (8) has a central hole with corresponding troughs (13) and ridges (14) for non-rotational locking of the disc to the hub. A slot (19) extends from alternate troughs in the brake disc to provide thermal relief for the hub section of the brake disc.
