Abstract
The utility model relates to a vehicle-mounted weighing sensor which is installed at the tail end of an automobile steel spring plate. The vehicle-mounted weighting sensor comprises a sensor front end (2), a sensor middle stress end (3) and a sensor rear end (4), two blind grooves (5) are symmetrically distributed in the sensor middle stress end (3), a strain gage (6) is attached to the bottom of each blind groove (5), two strain gages constitute a Wheatstone full bridge circuit which senses the weight of an automobile. When the vehicle-mounted weighting sensor is used, the sensor front end (2) is connected with an automotive frame or an automotive shaft, the sensor rear end (4) is connected with the tail end of the automobile steel spring plate. The design principle of the vehicle-mounted weighting sensor is that a design of mature thin-wall pressure-direction normal stress is applied, and therefore the measuring accuracy is guaranteed. The vehicle-mounted weighing sensor can be suitable for installation of a single-shaft automobile steel spring plate and a shaft-coupling automobile steel spring plate at the same time, and therefore real-time detection of load of the automobile is achieved. In addition, the vehicle-mounted weighing sensor is simple in structure, convenient to install, and small in changing amount of an original structure of the automobile.
Description
Technical field
The utility model relates to a kind of LOAD CELLS, relates in particular to a kind of vehicular weighing sensor that is installed in the automobile spring plate end.
Background technology
At present, the work of state treatment highway overrun and overload has been implemented for many years, and the situation of serious overrun and overload is contained that effectively road traffic accident obviously descends, and the highway traffic efficiency obviously improves.The vehicle load metering outfit of administering the highway overrun and overload mainly is to adopt truck scale, main equipments such as axle load meter, and it costs an arm and a leg, the cost of installation height, and can't accomplish that vehicle load monitors in real time.The problem that vehicle load detects has in real time obtained research at home, and has proposed multiple terms of settlement, but since well do not solve install complicated, change big and problem such as measuring accuracy is low to vehicle structure, never be used widely.
The utility model content
The utility model proposes a kind of vehicular weighing sensor at the prior art deficiency, and is simple in structure, easy for installation, little to automobile original structure change amount, and can install on the automobile spring plate of single shaft and shaft coupling simultaneously, is applied to vehicle load and detects in real time.
The technical scheme that the utility model adopted:
A kind of vehicular weighing sensor comprises sensor front end (2), the middle force side (3) of sensor and sensor rear end (4); Force side (3) symmetrical distribution 2 blind grooves (5) in the middle of described sensor, strain-gauge (6) is posted in described blind groove (5) bottom, described strain-gauge (6) is formed the Hui Sideng full-bridge circuit, the perception vehicle weight, sensor front end during use (2) is connected with vehicle frame or axletree, and sensor rear end (4) are connected with automobile spring plate is terminal.
When sensor was installed in single shaft spring plate structure vehicle, sensor front end was connected with carriage frame, and vehicle load is delivered on the sensor by vehicle frame, converted to and the cooresponding electric signal output of vehicle load through the Hui Sideng full-bridge circuit.
When sensor was installed in shaft coupling spring plate structure vehicle, sensor front end was connected with axletree, and vehicle load is delivered on the sensor by spring plate, transferred and the cooresponding electric signal output of vehicle load through the Hui Sideng full-bridge circuit.
Described vehicular weighing sensor, sensor rear end prop up admittedly by bolt and are installed in the automobile spring plate end.
Described vehicular weighing sensor, the sensor rear end is fixed on the automobile spring plate end by the intermediate transit part.
Useful good effect of the present utility model:
1, the utility model vehicular weighing sensor, principle of design are to adopt ripe thin-walled to press to the normal stress design, have guaranteed measuring accuracy, the measuring accuracy height.Be installed in the vehicle spring steel plate end, gross vehicle weight equals the summation of the terminal sensor output weight of installing of all spring plates.
2, the utility model vehicular weighing sensor is simple in structure, and is easy for installation, little to automobile original structure change amount, and can be applicable to the installation of the automobile spring plate of single shaft and shaft coupling simultaneously, realizes that vehicle load detects in real time.

The specific embodiment
Embodiment one: referring to Fig. 1, Fig. 2, the utility model vehicular weighing sensor comprises sensor front end 2, the middle force side 3 of sensor and sensor rear end 4; Two blind grooves 5 of force side 3 symmetrical distributions in the middle of described sensor, strain-gauge 6 is posted in described blind groove 5 bottoms, and described strain-gauge 6 is formed Hui Sideng full-bridge circuit, perception vehicle weight, sensor front end 2 is connected with vehicle frame or axletree during use, and sensor rear end 4 is connected with automobile spring plate is terminal.
As seen from Figure 3: when vehicular weighing sensor 1 is installed on the single shaft spring plate 7 structure vehicles, sensor rear end 4 is completely fixed in automobile spring plate 7 ends, sensor front end 2 is connected with carriage frame 8 by intermediate connector 9 or 10, vehicle load is delivered on the sensor 1 by vehicle frame 8, and the Hui Sideng full-bridge circuit of forming by the blind groove 5 bottom strain-gaugies 6 of force side 3 in the middle of the sensor converts cooresponding electric signal output to.
As seen from Figure 4: when vehicular weighing sensor 1 is installed on the shaft coupling spring plate 7 structure vehicles, sensor rear end 4 is completely fixed in automobile spring plate 7 ends, sensor front end 2 is completely fixed on the Automobile shaft 11, vehicle load is delivered on the sensor 1 by automobile spring plate 7, and the Hui Sideng full-bridge circuit of forming by the blind groove 5 bottom strain-gaugies 6 of force side 3 in the middle of the sensor converts cooresponding electric signal output to.
