AI Technical Summary
In existing dual-air-path differential shafts, the tension generation air path and the expansion plate control air path cannot be controlled independently, resulting in mutual interference.
Independent first and second air intake groups were designed for the tension adjustment section and the expansion plate control section, respectively. The tension and the size of the expansion plate can be independently controlled by the up and down sliding of the slip section and the movement of the piston. The tension can be precisely adjusted by utilizing the cooperation of the air intake and the piston.
It achieves independence of tension and expansion plate control, and the tension of the differential shaft is not affected during installation and disassembly. Furthermore, the tension of the differential shaft can be precisely controlled by adjusting the gas pressure.
