A method for increasing axial stiffness, reducing radial and deflection stiffness of an elastic compounded component, which can increase axial stiffness and reduce radial and deflection stiffness of the elastic compounded component by axial precompression and suspended load bearing structure its elastic subcomponent with multiple free surfaces, wherein the elastic subcomponent with multiple free surfaces is a compounded elastic component of elastic material and metallic components (2) , the elastic subcomponent has three or more free surfaces after being compounded, so that the stress of the elastic subcomponent in all directions is substantially reduced, and the fatigue life of the elastic subcomponent (3) is prolonged; the axial precompression means that the elastic subcomponent is always in an axial compressed state while they are working, so that the axial stiffness is substantially increased; the suspended bearing structure means (1) that at least one of the metallic component of the elastic subcomponent is in a suspended state while they are working, so that the metallic component does not bear the load in radial direction on one hand, and thus the elastic material at this position is in a shearing state completely and only provide very little radial and deflection stiffness, on the other hand, the suspended metallic component will bear the load in axial direction and make great contribution to axial stiffness, thereby increasing axial stiffness, reducing radial and deflection stiffness of the elastic compounded component.
