摘要： The load transducer for measuring forces and/or moments on a rotatable member. In one embodiment, the transducer includes an inner ring member attachable to a wheel hub and an outer ring member attachable to a wheel rim. At least one and, preferably, a plurality of beams unitarily extend between the inner and outer ring members and are circumferentially spaced apart. Each beam is formed of a stem and a perpendicular crossleg. Wells are formed in the exterior surfaces of the stem and the crossleg for mounting a strain gage in a force or moment measurement orientation. Additional strain gages may be mounted on the exterior sidewalls of each stem. The strain gages are inter-connected in a bridge configuration for measuring forces and moments exerted on the wheel. Bores formed in the stem and the crossleg provide a passage for the conductors from each strain gage to an electrical connector mounted between the inner and outer ring members.
