FIG. 3 is a front view showing an example of a four-spring tandem suspension for use in the present invention. FIG. 3 is a front view showing an equalizer in the prior art and an equalizer in the present invention. FIG. Figure 5 is a schematic diagram illustrating how the effective lever ratio changes when an equalizer with no eccentricity at the center of rotation and an equalizer with upward eccentricity are rotated by the same angle. Figure 6 shows the eccentricity of the equalizer's rotation center and the equalizing stroke (step stroke on the drive shaft mounting/lowering side that can maintain a constant equalizing characteristic, when the drive shaft load is 0.85 times the horizontal axle load of 1G loaded vehicle) Figure 7 is a diagram showing actual measured values of the relationship between the initial shaft angle of the driven shaft side and the equalizing stroke, and Figure 8 is a diagram showing actual measured values of the relationship between the shaft length and the equalizing stroke. Diagram showing actual measured values of relationship with equalizing stroke, No. 9
The figure is a diagram showing actual measured values comparing the equalizing characteristics of the suspension of the prior art and the suspension of the present invention with that of the balance arm type 4-spring suspension. It is a comprehensive equalizing characteristic diagram at the time of backward wind up. 1... Chassis frame; 2... Front hanger; 3... Center hanger; 4... Rear hanger;
