FLANGED HUB OF A WHEEL BEARING UNIT

摘要

The present invention resides in a flanged hub (120) of a wheel bearing unit (100) comprising a hub part (122) and a flange part (127), the hub part having a raceway (125) made of a bearing steel material and the flange part having a mounting surface (130) for the attachment of a brake rotor (140) and vehicle wheel rim. The flange part (127) predominantly comprises a second material that is joined to the hub part in a moulding process. According to the invention, the flange part further comprises an integrally moulded heat shield (150) made of a third material which, in comparison with the second material, has a lower coefficient of thermal conductivity.
