The invention discloses a vibration reduction suspension structure, and aims to provide a multi-stage vibration reduction suspension structure which is rich in vibration reduction means, good in vibration reduction effect and durable. The multi-stage vibration reduction suspension structure comprises an upper support, a lower support, main spring rubber and a supporting arm which is used for connecting an engine assembly; the main spring rubber comprises a main spring inner framework used for fixing the supporting arm and two main spring bases arranged on the two sides of the main spring innerframework in a bilateral symmetry mode; a vulcanized middle framework is arranged in the middle of the main spring rubber; the vulcanized middle framework comprises two side plates arranged in a bilateral symmetry mode and a bottom plate located between the side plates; the side plates are embedded in the ends, close to the main spring inner framework, of the main spring bases; a columnar limiting rubber block is arranged below the bottom plate; first gaps exist between the main spring inner framework and the side plates; and a second gap exist between the limiting rubber block and the lowersupport. With the multi-stage vibration reduction suspension structure adopted, multi-stage vibration isolation can be achieved, the problem that the high-frequency dynamic stiffness of a pure rubbersuspension is too high is solved, and NVH performance is optimized.
本发明公开了一种减振悬置结构,旨在提供一种减振手段丰富、减振效果好、经久耐用的多级减振悬置结构。它包括上支架、下支架、主簧橡胶和用于连接发动机总成的托臂,所述主簧橡胶包括用于固定所述托臂的主簧内骨架和两个左右对称布置在主簧内骨架两侧的主簧基座,主簧橡胶中部设有硫化中骨架,所述硫化中骨架包括两个左右对称布置的侧板和位于侧板之间的底板,侧板嵌设在主簧基座邻近主簧内骨架的一端,所述底板下方设有柱状的限位胶块,所述主簧内骨架与侧板之间存在第一间隙,限位胶块和下支架之间存在第二间隙。采用本设计,能够实现多级隔振,解决纯橡胶悬置高频动刚度过高的问题,优化NVH性能。
