WEIGHING MODULE FOR STATIC OR DYNAMIC WEIGHING OF LOADS AND FORCE TRANSMISSION APPLIED THEREBY

摘要

A weighing module for statically or dynamically weighing loads, and this weighing module (1) consists of a main frame (2), an auxiliary frame (3) on which the loads to be weighed are placed, and between the two frames (2 and 3) there is a force sensor (4) for measuring or determining the forces exerted on the force sensor (4), whereby between the force sensor (4) and the auxiliary frame (3) there is an elastic force transmission (5) or 'elastomer' for transmitting the forces from the auxiliary frame (3) to the main frame (2), primarily along a vertical direction (Ζ-Ζ') and a horizontal direction (X-X', Y-Y' ), characterised in that the force transmission (5) consists of a first elastic compressible element (6) that is held in the vertical direction (X-X' ) between a first housing part (7), by which the force transmission (5) is secured to the auxiliary frame (3) or forms part of it, and a second housing part (8) located below it that is movable with respect to the first housing part (7), and whereby the force transmission (5) rests on the force sensor (4) for a direct vertical force transmission via the first elastic element (6), and whereby at rest an open play (9) is left between the two housing parts (7 and 8), at least along two horizontal directions (X-X' and Y-Y' ) that are transverse to one another, in order to enable, when there are limited horizontal forces on the auxiliary frame (3), a limited horizontal freedom of movement up to the play between the two housing parts (7 and 8), thanks to the elasticity of the first elastic element (6), and whereby this play (9) is chosen such that when the horizontal forces exceed a certain value in an aforementioned horizontal direction, the play (9) in this direction is eliminated and both housing parts (7 and 8) come into contact with one another in the horizontal direction.
