Abstract
The utility model discloses an automatic load metering device for automobile. The automatic load metering device for automobile adopts a sensor with resistor foil gauge type double bend beam structure. The automatic load metering device for automobile is arranged on a cross beam under the box board of an automobile used for transporting goods. When the automobile loads, the carriage of the automobile is stressed, the sensor outputs 0-12 m V voltage signals, and the voltage signals are sent to a quadbit half number display meter arranged on a meter panel in the cab of the automobile for reading load value through an electric bridge circuit. The automatic load metering device for automobile has the advantages of simple structure, low cost, easy installation, accurate metering, visual display, etc.
Description
The utility model belongs to the automatic metering equipment of carload.
Usually for the loading metering of goods vehicle, mainly be to adopt evaluation method or ground heavily to weigh loadage is measured.The former is because the existing error of estimation makes purchasing unit or supply unit cause loss in various degree; Though latter's metering is more accurate, its equipment is installed complicated, needs certain place and fund, just is not difficult for installing if condition does not possess, and is not easy to apply.
The purpose of this utility model provides a kind of being installed on the goods vehicle, accurate measurement, measuring apparatus easy to use.
The utility model is to adopt resistance-strain chip double bent tube structure sensor to be installed on the crossbeam under the goods vehicle boxboard, when carload, railway carriage is stressed to sensor generation 0～12mv voltage signal, send four semi-digital-display-meters that install on the indoor panel board of car steering to read loading value through bridge diagram.
The utlity model has simple in structurely, cost is low, and is easy for installation, accurate measurement, and advantages such as intuitive display, easy to utilize, its advanced design, rationally.
Description of drawings:
Fig. 1 is an embodiment synoptic diagram of the present utility model.
Fig. 2 is a sensor construction synoptic diagram of the present utility model.
Fig. 3 is sensor of the present utility model installation site synoptic diagram on automobile.
The double bent tube sensor of installing below the automobile boxboard is one group four, the body of sensor (4) is installed in the interior (see figure 2) of housing (5), two ends respectively are the equilateral triangle edge of a knife below the body (4), have above apart from two equidistant equilateral triangle edges of a knife of the following edge of a knife, the quenching hardness of body (4) is HRC48-52, post (3) four of foil gauges above the body (4), the impedance of foil gauge (3) is 120 Ω, four tunnel outputs of foil gauge (3) connect together, and deliver to the bridge diagram input end by connection plug (6).When automobile loads, steel ball (1) moves downward and passes to body (4) through pressing plate (2) foil gauge (3) is deformed, output correspondent voltage signal, output voltage range is 0～12mv, but check weighing 0～8T, the voltage signal of bridge diagram output is connected to four semi-digital-display-meters in the pilothouse, shows load weight, the digital display meter model is ICL7135, measuring accuracy ± 1%.
The position that install for digital display meter (7) among Fig. 3, the position that install for sensor (8).
Claims (3)
1, a kind of automobile loading measuring apparatus, form by sensor and metering display, it is characterized in that sensor adopts resistance-strain chip double bent tube structure, be installed on the crossbeam under the goods vehicle boxboard, railway carriage is stressed during load-carrying, and sensor output 0～12mv voltage signal send four semi-digital-display-meters through bridge diagram.
