Abstract: A wheel hub assembly includes inner and outer hubs rotatably coupled by first and second ballsets of rollers. A plurality of sensors for sensing strain within the outer hub generated by the ballsets are disposed on exterior mounting surface sections. These surface sections are located at radial spacing distances within empirically derived radial boundaries to prevent interference from one ballset affecting the measurements taken by sensors monitoring the other ballset. To prevent excessive distortion of strain measurements taken through the outer hub, a certain amount of hub material is required to smooth signals generated by the first and second rollers passing proximal to each sensor, thus affecting the radial location of the mounting surfaces. Further, the sensor mounting surface sections are also located within empirically derived axial boundaries determined to enable each sensor to sense strain from one ballset while avoiding the detection of strain generated by the other ballset.

Abstract: An electrically conductive assembly is for a bearing disposed about a shaft and disposed within a housing. The conductive assembly includes an annular retainer coupleable with a bearing outer ring or with the bearing housing and having a centerline and an open inner end defining an annular groove. At least two and preferably several conductors each have a radially outer end disposed within the retainer groove and a radially inner end contactable with the shaft. Each conductor is formed of a plurality of conductive fibers arranged to extend radially inwardly from the retainer inner end. The at least two conductors are spaced apart circumferentially about the centerline so as to define at least two axial passages between the retainer and the shaft. Preferably, the conductors are separated by spacers formed of conductive fibers each having a length shorter than the length of the fibers of the conductors.

Abstract: A combined electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing. An annular insulator is disposeable about the bearing and configured to prevent electric current flow between an outer ring and the housing. An electrical conductor has retainer(s) releasably engaged with the insulator so as to couple the conductor with the bearing, an outer radial end and an inner radial end. The conductor outer radial end, or/and a portion of the conductor between the outer and inner ends, is conductively engageable with the housing and the conductor inner radial end is conductively engageable with the shaft so as to provide an electrically conductive path between the shaft and the housing. Preferably, the conductor includes a conductive disk having arcuate retainer clips engageable with an insulator groove of the insulator and a brush subassembly including conductive fibers engaged with the shaft outer surface.

Abstract: A strut mount and bearing assembly includes a strut mount having upper and lower ends, a central bore for receiving a shock absorber end and an annular upper race surface between the upper and lower ends and extending circumferentially about the bore. The upper end is fixedly connectable with a vehicle body and has a flat attachment surface disposeable against a vehicle surface of the vehicle body. A first bearing race is disposed on the mount and a spring seat having a second bearing race is movably coupled with the strut mount. The seat also has a lower end with spring engagement surface and a second bearing race is disposed on the seat spaced axially from the first bearing race. Rolling elements are disposed between the first and second bearing races to form a bearing. The various components are formed and sized to make an axially compact assembly.

Abstract: An insulated bearing assembly for coupling a shaft with an outer member includes an inner race disposed upon the shaft and an outer race disposed about the inner race and having an outer circumferential surface and axial ends. An annular insulator is formed of an electrically insulative and thermally conductive material and is coupled with either the outer race or the inner race such that the insulator is generally disposed between the outer race and the outer member or between the inner race and the shaft. A polymeric member has an annular portion(s) disposed against one of the two axial ends of the coupled outer race or inner race and an axial portion(s) extending from the annular portion and coupled with the insulator member so as to retain the insulator member coupled with the outer race or the inner race when the bearing assembly is separate from the outer member.
