A longitudinal variable-rigidity multilayer liquid rubber composite conical spring comprises a mandrel and a first bushing which are coaxially arranged, a conical rubber body is connected between the mandrel and the first bushing in a vulcanization mode, the rubber body is multilayer rubber, a plurality of partition plates are arranged on the rubber body at intervals, a pair of hollow hydraulic cavities is formed in the rubber body, and the hydraulic cavities are communicated with the first bushing. The hydraulic chambers are symmetrically distributed along the longitudinal direction relative to the mandrel, the opposite hydraulic chambers are communicated with a liquid flow channel, and at least one hydraulic chamber is communicated with a filling port communicated with the outside; the first lining is provided with a first opening, and the hydraulic cavity extends to the partition plate from the first opening to the central spindle in the longitudinal direction. When being subjected to longitudinal load, the longitudinal static rigidity is low under low-frequency load, the static rigidity is high under high-frequency load, the high dynamic-static ratio of the longitudinal rigidity is achieved, and meanwhile the influence of the vertical rigidity and the transverse rigidity is small under improvement and optimization.

    一种纵向变刚度多层液体橡胶复合锥形簧,包括同轴设置的芯轴和衬套一,在芯轴和衬套一之间硫化连接有锥型的橡胶体,所述橡胶体为多层橡胶,橡胶体间隔有若干隔板,在橡胶体内具有一对中空的液压腔室,所述液压腔室相对芯轴沿纵向对称分布,相对的液压腔室之间连通液体流道,至少一个液压腔室连通有和外部连通的灌注口;衬套一开设开口一,所述液压腔室自所述开口一沿纵向向芯轴延伸至隔板。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。
