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.
