ABSTRACT:
A diametral runout reducer adapted to drive a rotor for exciting a stator of a speed sensor located in a differential carrier. The rotor is driven by a diametral runout reducer. The runout reducer includes an annular axially extending member having a first end which engages a vehicle axle shaft driven by the differential case and a second end which drives the rotor. Intermediate the first and second end of the runout reducer is a radial protrusion disposed proximate the second end defining a peripheral surface which extends equidistantly from a central point. The rotatable axially extending flange defines a bore whose central axis is maintained coincident with a preferred axis of rotation by means of bearings supporting the differential case. The bore has a dimensional interrelationship with a radial protrusion which facilitates sliding, thereby maintaining the central point of the annular axially extending flange coincident with the preferred central axis. In this manner, diametral runout of the second end with respect to the first end is reduced by a factor determined by the distance between the central point and the first end divided by the distance between the central point and the second end. A stator element in an axial flange on the adjusting ring.
