Abstract:
The force-transmitting mechanism (400) includes a parallel-motion guide mechanism with a movable parallel leg (440), a stationary parallel leg, and at least two parallel-guiding members (450), wherein the parallel legs and the parallel-guiding members are connected to each other by flexure pivots and the movable parallel leg is constrained to the stationary parallel leg in guided mobility by the parallel-guiding members. The force-transmitting mechanism further includes a force-transmitting lever (480) which is pivotally supported on a fulcrum pivot (490) arranged on the stationary parallel leg, with a first lever arm (481) having a force-transmitting connection to the movable parallel leg by way of a coupling member (470), and a second lever arm (482) to which a measurement transducer (410) can be attached through a force-transmitting connection. The second lever arm includes a first partial lever arm (482A) and a second partial lever arm (482B), wherein the first partial lever arm is designed to receive the compensation force generated by the measurement transducer, and the second partial lever arm is designed for the detection of a displacement of the pivotally supported force-transmitting lever relative to a null reference of a position sensor (420).
