A longitudinal variable-stiffness inner-layer liquid cavity rubber composite conical spring comprises a mandrel and a first bush which are coaxially arranged, a conical rubber body is connected between the mandrel and the first bush in a vulcanized mode, a pair of hollow hydraulic cavities is formed in the rubber body, and the hydraulic cavities are symmetrically distributed relative to the mandrel in the longitudinal direction. A liquid flow channel is communicated between the opposite hydraulic cavities, and at least one hydraulic cavity is communicated with a filling opening communicated with the outside. The rubber body is made of multiple layers of rubber, a plurality of partition plates are arranged on the rubber body at intervals, the hydraulic cavity is located in the rubber body close to the innermost layer of the mandrel, and the second opening of the hydraulic cavity is adjacent to the side wall of the mandrel. The conical spring provided by the invention has low longitudinal static rigidity under a low-frequency load and high static rigidity under a high-frequency load when being subjected to a longitudinal load, so that a high dynamic-static ratio of the longitudinal rigidity is realized, the sealing performance of the hydraulic chamber arranged on the innermost layer is better, and meanwhile, a runner and a pouring channel are conveniently formed in the position of the core shaft.
一种纵向变刚度内层液体空腔橡胶复合锥形簧,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,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。所述橡胶体为多层橡胶,橡胶体间隔有若干隔板,液压腔室位于靠近芯轴最内层的橡胶体中,液压腔室的开口二和芯轴的侧壁邻接。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,并且最内层设置液压腔室密封性能更佳的同时,便于在芯轴处开设流道以及灌注通道。
