ABSTRACT:
A wheel bearing speed sensor includes an annular rotor mounted to a vehicle axle spindle, having a plurality of teeth extending radially outwardly, which is received within a stationary stator assembly. The stator assembly includes an annular stator having a corresponding plurality of teeth extending from one end and positioned proximate to the rotor teeth. A bobbin member is slidably received within the stator just above the radially aligned rotor and stator teeth and is restricted from movement toward the teeth. A flexible magnetic strip is magnetically adhered to the inner surface of the stator adjacent the bobbin member, wherein the magnetic strip restricts movement of the bobbin member axially away from the radially aligned teeth. A variable reluctance magnetic flux path is established simultaneously between all of the rotor and stator teeth as the spindle rotates, thereby inducing a corresponding variable voltage in the bobbin windings.
