[0002] The working principle of the ball joint damper mainly relies on the viscous resistance of the fluid or the compression and flow of the gas to dissipate the vibration energy. When the system is vibrated, the rocker will drive the rolling ball joint to move in the oil chamber or air chamber, and the resistance of the fluid (or gas) will hinder this movement, thereby converting the vibration energy into heat energy or other forms of energy consumption.
[0003] According to the description in the disclosed hinged gap elimination structure for viscous damper (authorization announcement number: CN215054163U), "the hinged gap elimination structure for viscous damper includes a damper, a ball joint is fixed at each axial end of the damper, and each of the ball joints is matched and connected to a base; the base includes a bottom plate and a hemispherical portion fixedly connected to the bottom plate, the ball joint is matched and connected to the hemispherical portion, the inner wall thread of the hemispherical portion is matched and connected to the outer peripheral thread of the pressure cover, and the inner hemispherical matching surface of the pressure cover is pressed and matched with the axial outer end of the ball joint.
