SHEET METAL SHIELD AND A WHEEL END ASSEMBLY PROVIDED THEREWITH

摘要

The invention concerns a sheet metal shield (1) that is adapted to be mounted against a radially extending flange (15) of a flanged hub (11), where the flanged hub is made of a metallic material and further comprises a shaft section (13) that is adapted to be coupled to a rotating part of at least one rolling element bearing (23). In order to provide the radially extending flange (15) with corrosion protection, at least the surface of the shield (1) that is in contact with the flange (15) consists of a sacrificial metal with a higher galvanic potential than the metallic material from which the flange (15) is made. Thus, in the presence of an electrolyte such as moisture, the shield (1) will sacrificially corrode to protect the flange (15). The invention also concerns a wheel end assembly provided with a sacrificial sheet metal shield.
