Abstract
The utility model provides an automobile weighing apparatus which is mainly composed of a weighing meter, a sensor, a working circuit which is connected with the weighing meter and the sensor, the sensor mainly comprises a driving axle (3), a groove wheel (4), a gear set, a variable resistance (5) and a reset spring (6), wherein, the groove of the groove wheel (4) is matched with the driving axle (3), which means that the axial movement of the driving axle (3) drives the groove wheel (4) to rotate without relative slide; the rotation of the groove wheel (4) drives a regulating shaft (7) of the variable resistance (5) to rotate through the gear set.
Description
The utility model relates to a kind of device of judging the contained goods weight of automobile.
Existing carload weighing device mainly adopts on-ground weigher, weighs with on-ground weigher etc. and can not accomplish at any time, weigh everywhere, and it is convenient inadequately to use.
The purpose of this utility model provides a kind of automobile weighing machine of can be at any time, automobile institute dead weight capacity being measured everywhere.
To achieve these goals, technical solution of the present utility model is such: the automobile weighing machine is mainly heavily shown by meter, sensor, the connection meter is heavily shown and the operating circuit of sensor constitutes, wherein, sensor mainly comprises transmission shaft, drop center wheel, gear set, variable resistor and back-moving spring, it is that moving axially of transmission shaft drives drop center wheel and do not have relative to rotating slidably that the groove of drop center wheel and transmission shaft match, the rotation of drop center wheel is rotated by the variable-resistance regulating shaft of gear set drive, when no external force is done the time spent, back-moving spring resets transmission shaft, sensor is installed on the fixed head of automotive wheel steel spring plate top, and its transmission shaft bottom is towards steel spring plate.
Because in the above-mentioned technical solution, the transmission shaft bottom of sensor is towards steel spring plate, steel spring plate is subjected to the effect of goods pressure when the automobile loading, transmission shaft is pushed by steel spring plate move certain distance, the variable-resistance regulating shaft of drop center wheel, gear set drive that moves through of transmission shaft rotates, make variable-resistance resistance value change certain numerical value, the corresponding change of reading that the change of this resistance value is heavily shown the meter that links together by operating circuit and sensor, thereby the purpose that can realize at any time, everywhere automobile institute dead weight capacity be measured.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural representation of sensor among the utility model embodiment.
Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is the circuit theory diagrams of the utility model embodiment work.
Wherein: 1, meter is heavily shown; 2, sensor; 3, transmission shaft; 4, drop center wheel; 5, variable resistor; 6, back-moving spring; 7, regulating shaft; 8, set screw; 9, clamp nut; 10, gear wheel; 11, pinion wheel; 12, semifixed resistor; 13, configuration resistance.
As Fig. 1, sensor shown in Figure 2 mainly comprises transmission shaft 3, drop center wheel 4, gear wheel 10, pinion wheel 11, variable resistor 5, back-moving spring 6, wherein the regulating shaft 7 that can correspondingly drive variable resistor 5 that moves up and down of transmission shaft 3 rotates, thereby change the resistance value of variable resistor 5, the bottom of transmission shaft 3 is provided with set screw 8 and clamp nut 9, therefore the active length of transmission shaft 3 can do different adjustment, the working surface of drop center wheel 4 is that rubber layer makes the cooperation of itself and transmission shaft 3 more accurate, be difficult for producing relatively and slide, in sensor, also be provided with a semifixed resistor 12 near the variable resistor 5, variable resistor 5 and semifixed resistor 12 coupled in series.
When the automobile weighing machine that foregoing sensor is formed is applied to four-wheel automobile, the automobile weighing machine has four sensors 2, four sensors 2 are installed in respectively on the fixed head of four wheel steel spring plate tops, the circuit theory diagrams of automobile weighing machine work as shown in Figure 3, after connecting mutually, the resistance of four sensors 2 is connected on the operating circuit, a configuration resistance 13 also is set in the operating circuit, counts and form operating circuit realization the purpose of this utility model after heavily table 1 is connected with the resistance that disposes resistance 13 and four sensors 2.
When the automobile weighing machine was applied to tricar or other automobile, the quantity of sensor can make corresponding changes, and can realize the purpose of this utility model equally.
