Above-mentioned elastic body can be made by the alloy steel of the high strength limit, mainly is weight to be converted to can measure electric signal, so that follow-up computing.
Above-mentioned carrying base can be made by pure stainless steel, and the transmission of holding capacity makes elastic body form the effect of stress surface, contacts with foundation ditch simultaneously, and the displacement of limiting sensor guarantees operating accuracy.
Above-mentioned spacer pin can be made by stainless steel, and restriction is subjected to displacement because of the transverse force of vehicle makes between carrying base and the elastic body.
As preferably, above-mentioned elastomeric 2 ends evenly are provided with several strain bores respectively, are respectively equipped with foil gauge in the strain bore, constitute several strainometers, are in series between the strainometer and/or in parallel.Above-mentioned structure is formed resistance bridge, has better linearity, and horizontal one is straightforward.Preferred again mode is: above-mentioned elastomeric 2 ends evenly are provided with 4 strain bores respectively, constitute 8 strainometers.
As preferably, to fixedly connected by screw A between above-mentioned bearing plate, yielding rubber pad and the elastic body, screw A is arranged in the screw mounting hole A on the elastic body.
As preferably, the screw B that passes through between above-mentioned elastic body and the carrying base is fixedlyed connected, and screw B is arranged in the screw mounting hole B on the elastic body, and is provided with spacer pin in described screw mounting hole B.Spacer pin is made by stainless steel, and restriction is subjected to displacement because of the transverse force of vehicle makes between carrying base and the elastic body.
As preferably, above-mentioned elastic body skin is provided with protective paint.
As preferably, above-mentioned carrying base and elastic body surface of contact are provided with some protruding blocks, form overload protection arrangement, prevent to destroy sensor because of overload.
Technical deficiencies such as the utility model has overcome the conventional dynamic truck scale and used the precision of sensor not high owing to adopted above-mentioned technical scheme, and less stable is easily got rusty, and is fragile, the measuring accuracy of raising sensor, long-time stability.
