ABSTRACT:
A wheel speed sensor for a wheel mounted on the end of an axle shaft of a drive axle can be utilized in an anti-wheel lock brake control system. The sensor includes an electromagnetic sensing device which is mounted on the drive axle housing in alignment with the axle shaft inwardly of the wheel. An excitor rotor of the sensor is preferably mounted on the differential casing about the axle shaft in alignment with the sensing device for rotation while maintaining the distance between the sensing device and the rotor within a predetermined limit without allowing contact therebetween. A C-shaped spring partially encircles the rotor as a pair of tabs at its ends extend inwardly through the rotor to make contact with a corresponding pair of grooves in the axle shaft. The C-shaped spring member drives the rotor in response to rotary movement of the axle shaft but allows removal of the axle shaft for maintenance while the rotor is retained within the protective interior of the housing.
