An exciter ring assembly to detect rotational parameters of an axle within
a tube has an exciter ring attached to the axle by an elastomer insert.
The insert provides a frictional interference fit with the axle. The
insert affixes the exciter ring to rotate with the axle. The elastomer
insert is supplied with radially-spaced axial channels to enable oil flow
past the assembly. The outer member of the assembly is press fit into the
axle tube. The outer member remains stationary with respect to the axle
tube. The outer member restricts the axial movement of the exciter ring
and enables rotation of the exciter ring and provides oil flow across the
exciter ring assembly.
