The invention discloses a hydraulic suspension structure, and aims to provide the hydraulic suspension structure with stronger shock absorption and energy absorption effects and better sealing performance. The structure comprises a bottom plate bracket, a main spring rubber, an upper liquid cavity and a lower liquid cavity. The main spring rubber, the upper liquid cavity and the lower liquid cavity are sequentially arranged from top to bottom. An opening connected with the upper liquid cavity is arranged in the main spring rubber, a protruding strip is arranged in the opening, the protruding strip is arranged on an inner side wall of the main spring rubber in a circumferential direction, a first annular groove is arranged in the bottom of the main spring rubber and formed in the outer sidewall of the main spring rubber, an annular buckle matched with the first annular groove is arranged on an upper edge of the bottom plate bracket, and the annular buckle is in interference fit with the first annular groove. By the adoption of the design, a problem that a dynamic hardening frequency of hydraulic suspension is too low can be solved, a liquid seal percent of pass is increased, and reliability of the hydraulic suspension is effectively improved.

    本发明公开了一种液压悬置结构,旨在提供一种减震吸能效果更强、密封性能更好的液压悬置结构。它包括底板支架、主簧橡胶、上液腔和下液腔,主簧橡胶、上液腔和下液腔从上至下依次布置,主簧橡胶内部包括与上液腔连通的开口,开口中设有凸条,凸条周向设置在主簧橡胶的内侧壁上,主簧橡胶底部设有第一环形凹槽,第一环形凹槽布置在主簧橡胶的外侧壁上,底板支架上缘设有与第一环形凹槽适配的环形卡扣,环形卡扣与所述第一环形凹槽为过盈配合。采用本设计,可以解决液压悬置动态硬化频率过低问题且其中的液封合格率得到提高,使液压悬置的可靠性得到有效提升。
