Referring to fig. 3 and 4, fig. 3 and 4 are schematic diagrams of the four-wheel independent hydraulic damping system of the present invention. When the vibration damping chassis 1 runs on a flat road surface, the dead weight of the vibration damping chassis 1 and the upward thrust generated by the hydraulic oil cylinder 16 are balanced, the tire mounting frame 14 is in a stable state, and the piston rod 161 of the hydraulic oil cylinder 16 is in a pre-extending position. When a certain tire of the vibration reduction chassis 1 meets a road surface bulge (see fig. 3), when the tire is turned over the bulge, an upward additional thrust is applied to the tire by the bulge, the original force balance is broken, the tire mounting frame 14 rotates upwards by taking the rotating pin shaft 133 as the center under the action of the additional thrust, the length of the hydraulic oil cylinder 16 connected between the oil cylinder connecting pin fixing plate 131 and the fixing plate 143 is shortened, the piston rod 161 is forced to move upwards, the volume of the inner cavity of the cylinder 162 is reduced, hydraulic oil in the inner cavity is pressed into the inner cavity of the energy accumulator 110 through the first communicating pipe 17, the tee joint 18 and the second communicating pipe 19, the hydraulic oil volume in the energy accumulator 110 is increased, the volume of the air chamber is reduced, the gas pressure is increased. When the tire mounting bracket 14 is rotated upward around the rotation pin 133 by the additional thrust, the length of the hydraulic damper 113 connected between the damper connecting pin fixing plate 132 and the fixing plate 143 is simultaneously shortened, the piston moves upward, the volume of the upper chamber 1131 becomes small, the pressure rises, and the oil in the upper chamber 1131 flows into the lower chamber 1132 through the orifice. Due to the orifice, a large damping force is generated in the opposite direction (downward direction) to the movement direction of the piston when the oil flows, so that the vibration is damped. Vibrations transmitted by the tires to frame 12 are effectively damped and isolated by the combination of hydraulic ram 16-accumulator 110 and hydraulic damper 113.

When the piston rod 161 extends downwards, the hydraulic oil stored in the accumulator 110 is pressed into the cylinder 162 through the second communicating pipe 19, the tee joint 18 and the first communicating pipe 17, the volume of the air chamber in the inner cavity of the accumulator 110 is increased, the gas pressure is reduced, and the absorbed energy is released. When the tire mounting frame 14 rotates downward around the rotation pin 133, the length of the hydraulic damper 113 is increased, the piston moves downward, the volume of the lower cavity 1132 is reduced, the pressure is increased, oil in the lower cavity 1132 flows into the upper cavity 1131 through the throttling hole, and the oil generates a damping force in the upward direction when flowing, so that the vibration is attenuated. Vibrations transmitted by the tires to frame 12 are effectively damped and isolated by the combination of hydraulic ram 16-accumulator 110 and hydraulic damper 113. The amplitude of the vibrations of the frame 12 is reduced to 4 compared to the road pit depth 3 (see fig. 4).
