Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
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 and being of a type which includes an excitor ring mounted within a hub cap of said wheel and a magnetic sensor device capable of electrically transmitting a speed signal through electrical wiring extending through the interior of said axle; wherein the improvement comprises: said sensor device being disposed within a sensor housing; said sensor housing being disposed within said hub cap and mounted thereon for relative rotation about a central axis of said hub cap with said sensor device in alignment with said excitor ring; said sensor housing having a connector portion generally extending toward and aligned with said open-ended spindle and electrically coupled to said wiring when said hub cap is secured on said wheel; and means disposed between said spindle and said sensor housing for providing frictional contact therebetween to prevent relative rotation of said spindle and said sensor housing during operation of said assembly.
Claim 2
Dependent Claim
172 words
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 and being of a type which includes an excitor ring mounted within a hub cap of said wheel and a magnetic sensor device capable of electrically transmitting a speed signal through electrical wiring extending through the interior of said axle; wherein the improvement comprises: said sensor device being disposed within a sensor housing; said sensor housing being disposed within said hub cap and mounted thereon for relative rotation about a central axis of said hub cap with said sensor device in alignment with said excitor ring; said sensor housing having a connector portion generally extending toward and aligned with said open-ended spindle and electrically coupled to said wiring when said hub cap is secured on said wheel; and means disposed between said spindle and said sensor housing for providing frictional contact therebetween to prevent relative rotation of said spindle and said sensor housing during operation of said assembly.
Claim 3
Dependent Claim
31 words
