1. A wheel sensor configuration for a vehicle comprising:
- an axle defining a centerline;
a wheel hub surrounding said axle;
at least one nut mounted on an end of said axle, said nut having a predetermined inner diameter thereby defining an inner diameter dimension around said axle;
a hub cap mounted to said wheel hub;
an exciting element mounted within said hub cap;
a member mounted on an end of said axle and having a portion which extends outwardly from said end of said axle;
a sensor provided on said portion of said member, said sensor and said exciting element being concentrically arranged from each other relative to said centerline of said axle and being radially spaced apart from each other relative to said centerline of said axle, said sensor being configured to sense said exciting element, said sensor having an outermost extent that does not extend beyond said inner diameter dimension of said nut, said sensor being spaced from said exciting element; and
a controller connected to said member to determine a predetermined property of said wheel hub.

Abstract
A system for a vehicle includes a hollow axle, a wheel hub which surrounds the axle, bearings provided therebetween, at least one nut having a predetermined inner diameter mounted on an end of the axle, and a hub cap mounted to the wheel hub. An exciting element is mounted within the hub cap by a mounting wheel. A sensor member is mounted in the end of the axle and radially spaced from the exciting element. The sensor member has an outer diameter which is less than the inner diameter of the nut such that the wheel hub, the bearings, the nut, the hub cap, the exciting element and the mounting wheel can be removed without having to remove the sensor member from the axle.

15. A wheel sensor configuration comprising:
-
an axle defining a centerline;
a wheel hub mounted on said axle;
at least one bearing disposed between said axle and said wheel hub;
a hub cap mounted to said wheel hub;
an exciting element disposed generally within said hub cap;
a member disposed at an end of said axle; and
a sensor on said member, said sensor and said exciting element being concentrically arranged from each other relative to said centerline of said axle and being radially spaced apart from each other relative to said centerline of said axle, said sensor configured to sense said exciting element, said member and said at least one bearing configured such that said at least one bearing is removable from said axle without having to disengage said member and said sensor from the end of said axle. - View Dependent Claims (16, 17, 18, 19)
