Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
In combination with an elongate vehicle axle and a wheel rotatably mounted on said axle, a wheel speed sensor assembly comprising a ring member having discontinuities on a radial face thereof, said ring member being secured by a press fit about a portion of said wheel for rotation therewith with said discontinuities facing axIally inwardly, a magnetic sensor assembly, a mounting member for said sensor assembly, said mounting member having an axially outwardly facing radial face supporting said sensor assembly and an axially extending annular portion secured by a press fit onto said axle, said sensor assembly and said ring being disposed in a predetermined relation with a predetermined spacing betwen said sensor and said discontinuities on said ring.
Claim 2
Dependent Claim
119 words
