ABSTRACT:
An annular wheel speed sensor having an efficient magnetic configuration to provide a high level of electrical output even at relatively low wheel speeds. The sensor comprises a magnetic tone ring having both axial and radial magnetic fields and a stator configured to read both the axial and radial magnetic fields as the tone ring rotates. The sensor is configured to minimize the effects of variation in the axial air gap between the tone ring and stator to provide an accurate and reliable wheel speed signal. The wheel speed sensor incorporates many of the bearing components to provide a compact and efficient hub and bearing assembly. Moreover, the construction of the hub and bearing of the invention provides a sealed environment for the speed sensor, isolating it from environmental factors.
