Patent ID: 7360756

Claim:
A bushing assembly comprising: an outer member; an inner member arranged substantially concentrically with the outer member; an elastomeric member disposed between and interconnecting the inner and outer members; and a sensor assembly at least partially embedded within the elastomeric member intermediate said inner and outer members, said sensor assembly comprising, a stator assembly including a first flux guide carried by one of said members for displacement therewith, a rotor ring including a second flux guide carried by the other of said members for displacement therewith concentrically with said stator assembly, said first and second flux guides defining opposed pole faces defining a radial air gap therebetween, a magnet magnetically coupled with one of said flux guides, a galvanomagnetic position sensing element coupled to one of said flux guides, and an inductor magnetically coupled with one of said flux guides and operative to generate an output voltage signal as a direct function of the instantaneous relative speed of rotation between said stator assembly and rotor ring.
