ABSTRACT:
A transducer which includes a central portion (12) having two longitudinally extending parallel rigid beam members (14,16) and two transverse parallel flexure members (30,32) which extend between the two rigid beam members (14,16) at right angles thereto. The rigid beam members (14,16) include end element portions (18,20). Flexure joints (58,60) and mounting portions (62,64) are located longitudinally outboard of the flexure joints (58,60). The flexure members (30,32) each include two cutout portions (34,36,40,42) defining flexure points. Strain gauges (46,48,50,52) are placed in the vicinity of the cutout portions (34,36,40,42) and are electrically connected into a bridge to produce an electrical signal output indicative of the load on the vehicle. The transducer is mounted by means of a mounting element (79) which includes two opposing mounting pad portions (82,84) and an intermedicate center portion (86). The mounting pad portions (82,84) are secured to a base member (87) on the vehicle, and then the center section (86) is removed, with the transducer then being securely and precisely connected between the two remaining mounting pad portions (82,84).
