ABSTRACT:
The weighing device for wheel loads has a platform (3) which distributes the load over a plurality of elongated hollow elements (2) disposed parallel with and at equal distances apart from and alongside one another on a baseplate (1). The hollow elements (2) consists of springing material and their cavities (12) are filled with fluid. A connecting line links the cavities (12) to a measuring device which is calibrated in units of weight and measures the volume of fluid displaced from the cavities (12) under load. The cavities (12) in the hollow elements (2) have a split or gap-shaped cross-section, and are substantially parallel with the platform (3). The gap width in the hollow elements (2) is so dimensioned that the inside faces of the hollow elements (2) which define the gap (12) at least partially abut each other when the weighing device is overloaded, prior to the elasticity limit of the hollow elements (2) being reached. By virtue of the cross-sectionally split or gap-shaped construction of the cavities (12 ), a plastic deformation of the hollow elements (2) is easily avoided without the disposition of rod elements in the cavities.
