The specific embodiment
See Fig. 1 and Fig. 2; Present embodiment comprises vehicle frame 1, front frame 2, after poppet 3, steel spring 4 and vehicle bridge 5; Steel spring 4 is fixed on the vehicle bridge 5, and said forward and backward support 2,3 is connected to the front and back end of vehicle frame 1, and the two ends of steel spring 4 are connected on the forward and backward support 2,3.Be provided with height sensor 6 between said vehicle bridge 5 and the vehicle frame 1, said height sensor 6 has housing 6-1, S. A. 6-2, two photoelectrical coupler 6-3, blanking disc 6-4, connecting rod 6-5 and pull bar 6-6; Said housing 6-1 is fixed on the vehicle frame 1; Said S. A. 6-2 is supported by the pair of bearings that is installed on the housing 6-1; Said blanking disc 6-4 is in the housing 6-1 and is fixed on the said S. A. 6-2, and blanking disc 6-4 is provided with unequal interval and length has three different light tank 6-4a, and said two photoelectrical coupler 6-3 are to differ 180 ° fixed angle on housing 6-1; Blanking disc 6-4 rotates; Two photoelectrical coupler 6-3 accept the optical signal from light tank 6-4a, are fixed with sensor stand 7 by U-bolt on the vehicle bridge 2, and the lower end of said pull bar 6-6 is hinged on the sensor stand 7; The end of the upper end of pull bar 6-6 and connecting rod 6-5 is hinged, and the other end key of connecting rod 6-5 is connected on the S. A. 6-2.
Increase along with vehicle loading weight; Steel spring 4 deflections increase; Distance between vehicle frame 1 and the vehicle bridge 5 changes; Sensor pull bar 6-6, drives blanking disc 6-4 through connecting rod 6-5 again and rotatablely moves, thereby the conducting state of two photoelectrical couplers is changed along with vehicle bridge 5 moves up with respect to vehicle frame 1 with sensor stand 7.Calibrate the relation between height sensor output signal and the car load in advance, can judge the overload situation of vehicle through the conduction status of two photoelectrical couplers.
When photoelectrical coupler can't accept optical signal, the photoelectrical coupler output circuit ended; When the light tank position to the photoelectrical coupler place, the conducting of photoelectrical coupler output circuit.Rotation along with blanking disc; Two photoelectrical couplers combine to have " conducting, by ", " by, conducting ", " conducting, conducting " reach " by, by " four kinds of states, corresponding respectively according to demarcating in advance " not overload ", " overload 0-10% ", " overload 10-20% " reach " overloading more than 20% ".
On starter power line, fuel injector supply line and ignition signal line, install a contact normally closed solenoid valve respectively additional, be used to control the conducting of three circuits and end.
See Fig. 3, the control system of present embodiment comprises height sensor, car speed sensor, control unit, starter power line electromagnetic valve, fuel injector supply line electromagnetic valve, ignition signal line electromagnetic valve and overload warning device.Height sensor is used to discern the overload situation of vehicle, and car speed sensor is used to judge whether vehicle is quiescence.The overload of vehicle warning device comprises overload warning light and audible alarm unit, is installed in the operator's compartment.When electromagnetic valve coil does not have electric current to pass through, the electromagnetic valve closing of contact, place circuit turn-on; When electromagnetic valve coil has electric current to pass through, the electromagnetic valve contact open, the place circuit ends.
See Fig. 4, the native system control flow is following: control unit at first judges through car speed sensor whether vehicle is quiescence, if be not quiescence, considers the vibration effect of vehicle along with Uneven road, and the overload control system is inoperative; If quiescence, control unit judges according to height sensor whether vehicle overloads.If vehicle is overload not, then control system is not worked; If overload capacity is in 0-10%, then control unit sends instruction and makes overload warning light Chang Liang, and the sound prompting device sends and " note that vehicle has reached limit load! " sound prompting; If overload capacity is in 10-20%, then control unit sends to instruct the overload warning light is glimmered at a slow speed, and the sound prompting device sends and " note that vehicle has exceeded rated load! " sound prompting; If overload capacity is more than 20%, then control unit sends instruction and makes the fast blink of overload warning light, and the sound prompting device sends that " vehicle seriously overloads, and forbids vehicle '! " sound prompting; give the coil electricity of starter power line electromagnetic valve, fuel injector supply line electromagnetic valve, ignition signal line electromagnetic valve simultaneously; cut off starter power line, fuel injector supply line and ignition signal line, driving engine can't be started or normal operation, the Don't Exceed Weight Limit vehicle '.
