Abstract
The invention discloses a load capacity self-measuring transducer of a freight vehicle. The transducer comprises a transducer shell body, hydraulic medium, a pressure transducer, a n-shaped fixed steel tube, a guide wire and a piston device, wherein the piston device is respectively formed by two piston rods and two piston plates and the upper portion and the lower portion of the piston device are symmetrical, the hydraulic medium is filled between the upper portion of the piston device and the lower portion of the piston device, the pressure transducer is installed on a fixed steel plate and converts a pressure value to an electrical signal, the middle section of the fixed steel tube bypasses an axle, the right end and the left end of the fixed steel tube penetrate through the fixed steel plate, the shape of the fixed steel tube is n-shaped, and the guide wire is used for transmitting the signal output by the pressure transducer to a cab and showing in a form of a weight numerical value finally. The transducer has the advantages of being simple in structure, stable in operation and accurate in measurement, and not damaging the structure of an original car body because the whole device is installed on the bottom portion of a steel plate spring of the original car body. Through the hydraulic medium, the pressure is distributed uniformly to be passed on conveniently and the device is also good in reset function and with the change of load weight, the piston device changes in real-time mode under an effect of the hydraulic medium and the steel plate spring.
Description
Technical field
The present invention relates to a kind of measurement mechanism, especially relate to a kind of transport truck load carrying ability from survey sensor.
Background technology
Recently, the traffic accident that the heavy motor vehicle overload causes occurs again and again, and also road pavement has caused destruction simultaneously.And the detection of carload lot at present often will realize by being fixed near the weighbridge of detecting test station, has both affected traffic problems, has brought inconvenience also for driver or staff.Therefore annual solution overload problems has become the large problem of traffic management system.If the driver can understand in real time at operator's compartment the load condition of automobile, actv. is prevented the generation of vehicle overload from the source.Existing by weighbridge sense weight troublesome poeration, be unfavorable for that the driver is to the Real Time Observation of own vehicle capacity.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, provide a kind of transport truck load carrying ability from survey sensor, during use with described installation of sensors in transport truck steel spring bottom, by hydraulic medium, vehicle weight is passed to the pressure sensor of sensor base, finally by pressure sensor, the force value of weight is converted into electric signal and shows by read out instrument.
for solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of transport truck load carrying ability is from survey sensor, it is characterized in that: comprise sensor housing, respectively by two piston rods and two laterally zygomorphic piston apparatus that piston plate forms, be filled in the piston apparatus hydraulic medium between two parts up and down, be arranged on fixation steel plate and force value be converted into the pressure sensor of electric signal, the stage casing is walked around vehicle bridge and two ends, left and right and is passed fixation steel plate and be inverted U-shaped fixedly steel pipe, and the signal of pressure sensor output is passed to operator's compartment and the final wire that shows with weight numerical value, the upper end piston rod of described piston apparatus is connected to bottom steel spring, the lower end piston rod end of described piston apparatus is connected to the pressure sensor upper surface, described fixedly steel pipe and fixation steel plate are fixed by bolt tightening and housing and pressure sensor are surrounded, described steel spring is fixed on bottom vehicle bridge, described wire passes fixation steel plate and pressure sensor joins, and two piston plates and the hydraulic medium of described piston apparatus all are positioned at housing.
