Abstract
A method for sealing a liquid composite spring, includes the steps of: placing a sleeve-shaped outer wall around an upper portion of a core shaft, and forming an upper liquid chamber and a lower liquid chamber inside the outer wall; and arranging a sealing member at a bottom of the outer wall to seal the lower liquid chamber, wherein the sealing member is made of flexible material. The liquid composite spring is provided with the rigid outer wall and the flexible sealing member. The volume and shape of the lower liquid chamber can be changed through the flexible sealing member, so that the chamber is formed as a flexible chamber.
