In an embodiment as one of the present embodiments, each of the shock absorption assemblies includes an oil chamber and a damping piston 1 disposed inside the oil chamber, the oil chamber is divided into an upper oil chamber 2 and a lower oil chamber 3 by the damping piston 1, the top of the damping piston 1 is connected to a damping piston rod 4, and energy attenuation is realized by the up-and-down movement of the damping piston 1; the upper oil chambers 2 are communicated with each other through first oil passages 5, and the lower oil chambers 3 are communicated with each other through second oil passages 6.

As an example, the upper oil chamber 2 and the lower oil chamber 3 are sleeved with damping springs 7 on the peripheral sides, and the damping springs 7 are used for generating vibration when the wheels of the automobile are subjected to impact force.

As an example, a plurality of damping holes 8 are arranged on the damping piston 1, the damping holes 8 are used for repeatedly flowing hydraulic oil from one oil chamber to another oil chamber from the damping holes 8 when the damping piston 1 moves up and down in the oil chambers, the hydraulic pressures of the two oil chambers are inconsistent due to the damping action of the damping holes 8, the oil repeatedly flows in the oil chambers and generates friction with the wall of the oil chambers, so that damping force is formed on vibration, the vibration energy of the automobile is converted into oil heat energy, and the oil heat energy is emitted to the atmosphere, thereby having a damping action on the automobile.

In a specific embodiment, when one wheel of an automobile is subjected to a large external force, a damping piston 1 of a shock absorption assembly corresponding to the wheel moves downwards, at this time, the pressure of hydraulic oil in an upper oil chamber 2 of the shock absorption assembly is less than that of a lower oil chamber 3, the hydraulic oil in the upper oil chamber 2 flows into the upper oil chambers 2 of the other three shock absorption assemblies through a first oil path 5, the hydraulic oil in the lower oil chamber 3 flows into the lower oil chambers 3 of the other three shock absorption assemblies through a second oil path 6, so that the pressures of the upper oil chambers 2 of the four shock absorption assemblies are synchronous, the pressures of the lower oil chambers 3 are also synchronous, therefore, the pressures of the lower oil chambers 3 of the other three shock absorption assemblies are all greater than that of the upper oil chamber 2, the piston moves upwards synchronously under the pressure action, so that the acting force is uniformly dispersed to the four shock absorption assemblies for shock absorption, and the shock absorption effect is improved, the automobile is more stable in the driving process.

Furthermore, when the hydraulic oil circularly flows in the first oil path 5 and the second oil path 6, the oil temperature is reduced, the working temperature of the damping assembly is reduced, the damping assembly is protected from being easily broken in long-term use, and the service life of the damping assembly is prolonged.
