AI Technical Summary
In existing vibration damper structures, the installation angle is fixed, resulting in poor versatility. It is necessary to redesign the connecting seat or pin connection to change the installation angle.
The ball joint and ball head are designed to enable multi-angle installation through the multi-directional freedom of the ball head, and the tapered wall structure forms a uniform tightening preload on the friction-reducing sleeve to ensure the reliability of the vibration damper.
This technology enables multi-angle installation and adaptation of the vibration damper, maintains the axial force state, achieves the optimal vibration reduction effect, and improves the reliability and stability of the vibration damper.
