They can continuously and automatically adjust damping forces in real time to adapt to different driving conditions, providing a smoother and more comfortable driving experience. They enhance vehicle stability, reduce body roll and vibration, and improve handling and safety. Damping material has the characteristics of high-tech, non-toxic, pollution-free, high and low temperature resistance, aging resistance, chemical resistance and so on. In addition, the liquid spring is simple in structure, easy to install, and requires little maintenance.
