Abstract

The invention discloses a load capacity self-measuring system of a freight vehicle. The transducer comprises a self-measuring transducer device installed on the bottom portion of a steel plate spring of the freight vehicle, medium pipelines drawn forth from the bottom portion of the self-measuring transducer device, a pipeline connecting device used for enabling the tail ends of a plurality of the medium pipelines to be connected, a gathering device which is connected with the pipeline connecting device through a gathering pipeline and guide wires used for sending all signals sent by the gathering device to a cab and showing in a form of a weight numerical value finally. The load capacity self-measuring system has the advantages of being simple in structure, stable in operation and accurate in measurement, and avoiding damaging the structure of an original car body because the whole device is installed on the bottom portion of the steel plate spring of the original car body. Through hydraulic medium, not only is pressure transmitted in an even distributing mode conveniently, but also a good resetting function is achieved, and with the change of load capacities, a piston device changes in real time under the effects of the hydraulic medium and the steel plate spring.

Description

Technical field [0001] The invention relates to a measurement system, in particular to a self-measurement system for the load of a freight car. Background technique [0002] Recently, traffic accidents caused by overloading of heavy vehicles have occurred frequently, and they have also caused damage to the road. At present, the detection of the load capacity of a car often depends on a weighbridge fixed near the detection station, which not only affects the traffic problem, but also brings inconvenience to the driver 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 of the car in real time in the cab, it will effectively prevent the occurrence of overweight from the source. The existing operation of detecting the weight through the platform scale is troublesome, which is not conducive to the real-time observation of the load of the vehicle by the driver. Summary of the in...
