The conical spring provided by the invention has lower longitudinal static rigidity under a low-frequency load and higher static rigidity under a high-frequency load when being subjected to a longitudinal load, so that the high dynamic-static ratio of the longitudinal rigidity is realized, and meanwhile, the influence of the vertical rigidity and the transverse rigidity of the conical spring is smaller under the improvement and optimization of the conical spring. And the hydraulic cavity penetrates through the whole rubber body and has a large volume, so that the hydraulic cavity has smaller longitudinal static rigidity, and a larger dynamic-static ratio is realized. Due to the design of the hydraulic chamber, the arrangement of the communication runner and the filling port is very convenient.

    本发明提出的锥形簧,在受到纵向载荷时,低频载荷下具有较低的纵向静刚度,高频载荷下则具有较高静刚度,实现了纵向刚度的高动静比,同时在本发明的改进优化下其垂向刚度和横向刚度影响较小。并且由于液压腔室贯穿整个橡胶体具有较大的体积,使其具有更小的纵向静态刚度,从而实现更大的动静比。该液压腔室的设计使得连通流道和灌注口的设置十分便利。
