Hydro-pneumatic spring assembly

The hydro-pneumatic spring assembly comprises a base, a working cylinder and an energy storage cylinder, the base and the opening ends of the working cylinder and the energy storage cylinder are correspondingly sealed and fixed, a working piston and a piston rod are arranged in the working cylinder, and a movable blind hole is formed in the middle of the whole of the working piston and the piston rod from the end face of the working piston in the axial direction of the piston rod. A displacement sensing magnetic ring is arranged in the movable blind hole, an electronic bin is arranged at the position, right opposite to the first installation blind hole, of the movable blind hole, an induction rod is arranged on the electronic bin, the induction rod is matched with the electronic bin and used for measuring the displacement of the working piston, a two-way damping valve set is arranged on the bottom face of the second installation blind hole, and a circulation hole channel is formed in the base. One end of the
