ABSTRACT:
An anti-lock brake system includes a relatively low cost, toothed ring for sensing vehicle speed. The toothed ring can be molded out of an elastomeric material containing finely divided particulates that are magnetically permeable. The molded, toothed ring includes magnetically permeable projecting teeth which magnetically interact with a magnetic field generated in a speed sensor to provide a pulsating voltage related to vehicle wheel speed. The toothed ring can be an integral part of an oil seal or wear sleeve positioned between a vehicle axle and wheel hub.
