Ball Joint

They are generally made of elastic materials such as rubber, polyurethane, etc., which can absorb the impact force during movement, reduce the mechanical transmission of vibration, improve the comfort of riding and the service life of equipment.

In rail transit, Ball Joints are commonly used in the following situations:
1. Connection between tracks and equipment: such as bushings between wheels and tracks, which help absorb the impact generated during movement and reduce noise.
2. Connection between the train body and frame: Reduce the transmission of vibration during train operation and improve passenger comfort.
3. System buffering: such as buffers and shock absorbers, to prevent equipment damage caused by external impacts
