The invention discloses a feedback type hydraulic suspension which comprises a shell, a rubber main spring and a vibration isolation mechanism, a sealing cavity is formed by the rubber main spring and the shell, the sealing cavity is divided into an upper liquid chamber and a lower liquid chamber by the vibration isolation mechanism, the feedback type hydraulic suspension further comprises a first adjusting rod, a second adjusting rod, a first one-way valve and a second one-way valve, the elastic block comprises a fixed area and a deformation area, the fixed area is fixed to the shell, and the deformation area is located in the upper liquid chamber and the lower liquid chamber; the elastic block is provided with a liquid storage cavity, a second through hole and a third through hole. The first one-way valve and the second one-way valve are installed on the elastic block. According to the feedback type hydraulic suspension, the first adjusting rod or the second adjusting rod is driven to move through deformation of the rubber block, then the communication condition of the second communicating hole and the fourth communicating hole with the liquid storage cavity is adjusted, the deformation of the rubber block is determined according to the vibration frequency, and then the rubber block is made to adapt to different frequencies.

    本发明公开了一种反馈式液压悬置,包括壳体、橡胶主簧和隔振机构,橡胶主簧和壳体形成密封腔,隔振机构将密封腔分隔为上液室和下液室,还包括第一调节杆、第二调节杆、第一单向阀和第二单向阀,其中:隔振机构包括弹性块,弹性块包括固定区和形变区,固定区与壳体固定,形变区位于上液室和下液室;弹性块具有储液腔、第二通孔和第三通孔,第一单向阀和第二单向阀安装在弹性块上;本发明中,所提出的反馈式液压悬置,通过橡胶块形变进而带动第一调节杆或第二调节杆移动,进而调节第二连通孔和第四连通孔与储液腔的连通情况,而橡胶块的形变大小是根据振动频率大小来定的,进而使其适应不同频率。
