The elastically demultiplying dynamometer of the invention is divided into a frame bearer (1) and a load bearer (5) which are secured respectively to a frame (13) on the frame and to a load bridge (14) on the bridge side by means of screws (15) inserted through holes (2) in the frame bearer (1) and the load bearer (5). Both the frame bearer (1) and the load bearer (5) are secured to two short flexible rods (25) each with a vertical rod (6, 7); the two rods (6, 7) are in turn secured by two horizontal, superimposed, substantially parallel leaf springs (3, 4). From the rod (6) on the frame bearer side projects another leaf spring, referred to there as the measuring spring (10), substantially parallel and adjacent to the lower leaf spring (4) into the space between the rods (6, 7) and the leaf springs (3, 4); a similar measuring spring (11) projects from the rod (7) on the load bearer side substantially parallel and adjacent to the upper leaf spring (3) into the same space. A force sensor (12) is clamped between the two measuring springs (10, 11). The basic material for all the aforementioned components, except for the screws (15) and the force sensor (12), is a flat plate which is preferably divided and shaped into the components described and enumerated by wire erosion. It is thus possible to form the rod (6) and frame bearer (1) through a narrow slit (8) and the rod (6) and load bearer (5) through a similar narrow slit (9). |
