ABSTRACT:
An improved wheel speed sensor assembly for installation in association with a wheel rotatably mounted on a hollow axle which has an open-ended spindle is of a type which includes an excitor ring mounted within a hub cap of the wheel and a magnetic sensor device capable of electrically transmitting a speed signal through electrical wiring extending through the interior of the axle. The improvement includes the sensor device being disposed within a sensor housing which is, in turn, disposed within the hub cap and mounted thereon for relative rotation about a central axis of hub cap with the sensor device in alignment with the excitor ring. The sensor housing has a connector portion generally extending toward and aligned with the open-ended spindle and electrically coupled to the wiring when the hub cap is secured on the wheel. A friction and sealing member between the spindle and the sensor housing prevents relative rotation of the spindle and the sensor housing prevents lubricating fluid within the hub cap from entering the hollow axle through the open-ended spindle during operation of the assembly.
