Load capacity self-measuring transducer of freight vehicle

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 [0001] The invention relates to a measuring device, in particular to a load capacity self-measuring sensor of a freight vehicle. Background technique [0002] Recently, traffic accidents caused by overloading of heavy-duty vehicles have occurred frequently, and have also caused damage to road surfaces. At present, the detection of vehicle load capacity is often realized by the weighbridge fixed near the detection station, which has not only affected traffic problems, but also brought inconvenience to drivers or staff. Therefore solving the overload problem every year has become a big problem for the traffic management department. If the driver can know the load status of the car in real time in the cab, it will effectively prevent the occurrence of vehicle overweight from the source. The existing operation of detecting the weight through the weighbridge is troublesome, which is not conducive to the driver's real-time observation of the load capacity of his ...
