The wheel loading balance has a platform (1), of which one side (13) is, by a first pair of tibs (2), supported for horizontal movement on a first lever member (4) while the opposite side (14) is supported for horizontal movement on a second lever member (5) by a second pair of ribs (3). The two lever members (4, 5) are connected to each other pivotally and in such a way as to be secured against mutual displacement by a spring steel plate (33), being rotatably and horizontally movably mounted in a base (6) (38 to 41) at their remote ends (36, 37). One of the two facing ends of the lever members is rigidly connected to a pressure transmitting member (7) while the other is rotatably supported thereon (31,32). The pressure transmitting member (7) loaded by the lever members lies freely on a diaphragm (23) of a pressure force measuring cell (8) which together with a weight indicating pressure gauge and a connecting line (25) forms a component assembly which is exchangeably mounted in the base (6). The wheel loading balance is easily assembled, is rugged and accurate and its accuracy of measurement is not adversely affected by shocks or vibrations.

Balance, particularly a wheel loading balance

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.
