Abstract

A load cell (150) for transmitting forces and moments in plural directions includes a central hub (154), an annular ring (156) concentric with the central hub (154), and sensing structures (160) connecting the central hub (154) with the annular ring (156). In one embodiment, the sensing structures (160) include radial tubes (160). Each radial tube (160) has an outer surface (190) having a plurality of concave portions (196A, 196B, 198A and 198B). In another embodiment, the annular ring (156) includes spaced apart flanges (218A and 218B) that are adapted to support a tire.
