ABSTRACT:
An improved wheel mounting means is provided for a wheel speed sensor which is capable of being mounted at the end of a spindle and includes wiring which passes through a central passageway in the spindle. The sensor is of a type to be employed with a toothed ring or rotor mounted in the hub cap for relative rotation between the sensor and the rotor to generate a signal indicative of wheel speed. The improvement to the sensor includes providing the sensor with a support structure which can be bolted to a keyed lock ring of the wheel mounting assembly and which encircles an extended portion of the spindle to provide the desired coaxial alignment of the sensor and rotor. A sealing member between the support structure and the extended portion of the spindle prevents wheel bearing lubricating fluid in the hub cap area from escaping through the passageway in the spindle. The improved wheel mounting means, with or without the sensor being installed, includes an adjusting nut on the spindle against the wheel bearing, a keyed lock ring to prevent rotation of the adjusting nut, and a jam nut to prevent removal of the keyed lock ring. A pair of bolt means threaded into the keyed lock ring fit in close alignment with the flat edges of the jam nut to prevent its accidental removal whether or not the bolt means are also used to mount the sensor.
