ABSTRACT:
A speed sensor tone wheel has a plurality of serrations formed on an inner periphery for engagement with an axially extending annular surface formed on a wheel bearing seal support. The tone wheel is mounted on the support and an outwardly facing surface of the serrations is coined to force the inner ends of the serrations into contact with the annular surface to prevent relative rotation between the tone wheel and the support. Tabs can be formed in the outer periphery of a radially outwardly extending flange of the wheel bearing seal support for extending through open spaces between the serrations and engaging a surface of the tone wheel to trap the tone wheel between the support flange and the tab. Alternatively, an indentation can be formed in the flange to project into an associated one of the serrations.
