Embodiment Construction
[0026] figure 1 It is a schematic diagram of the structure and principle of the hydraulic disc spring mechanism of the double disc spring group accumulator in embodiment 1,
[0027] Such as figure 1As shown, the disc spring accumulator in embodiment 1 is a double disc spring group accumulator, which is symmetrically distributed on both sides of the working cylinder 11, the outer end of the disc spring group 3 is fixed, and the inner end is pressed against the outer end surface of the support ring 4 , The energy storage piston 5 tightly presses the inner end surface of the support ring 4 and is installed in the energy storage cylinder 2; the internal oil passage of the energy storage cylinder 2 communicates with the working cylinder 11. In this structure, the disc spring assembly 3 is mounted on the periphery of the accumulator bracket 27, which is pressed on the accumulator bracket 27 by the support ring 4, and the accumulator bracket 27 is connected with the accumulator cy...
