WHEEL HUB AND BRAKE DISC ARRANGEMENT

摘要

A wheel hub and brake disc arrangement (1) for a motor vehicle is proposed, comprising a wheel hub (2) with a wheel hub flange (3), wherein the latter has at least one receiving aperture (4), a brake disc (5) which is arranged adjacent to the wheel hub (2) and has a fastening flange (6), and at least one connecting bolt (7), for connecting the wheel hub and brake disc arrangement (1) to a vehicle wheel (13). The invention is distinguished in that the bolt head (9) of the connecting bolt (7) has at least one supporting portion (10) with an outer contour which deviates from the conceived circular shape of the bolt head (9) and corresponds to at least one portion of the outer contour of the fastening flange (6) of the brake disc (5), wherein the supporting portion (10) lies tangentially against the corresponding outer contour of the fastening flange (6) of the brake disc (5) and therefore forms a form-fitting connection with the fastening flange (6) of the brake disc (5), said form-fitting connection opposing an uncontrolled rotation of the connecting bolt (7).
