The invention discloses a pressure feedback type damping self-adjusting energy feedback oil gas suspension and a working method, and belongs to the field of vehicle oil gas suspensions. The pressure feedback type damping self-adjusting energy feedback oil gas suspension comprises a first-stage small-range damping multi-stage adjuster, a second-stage large-range damping multi-stage adjuster and a one-way energy feedback and energy recovery system, an oil outlet of the first-stage small-range damping multi-stage regulator is connected with an oil inlet of the one-way energy feedback and energy recovery system through an oil inlet pipe, an oil outlet of the one-way energy feedback and energy recovery system is connected with an oil inlet of the first-stage small-range damping multi-stage regulator through an oil return pipe, and a throttling valve is arranged on the oil inlet pipe. And pipelines at the two ends of the two-stage large-range damping multi-stage regulator are arranged on the two sides of the throttle valve on the oil inlet pipe in parallel. The working number of damping holes of the suspension system can be changed, self-adaptive adjustment of damping of the suspension system under the condition that the stroke is changed is achieved, power equipment is not needed, and automatic damping adjustment can be achieved through a mechanical structure. And damping vibration attenuation energy consumption recovery is realized.

    本发明公开了一种压力反馈式阻尼自主调节馈能油气悬架及工作方法,属于车辆油气悬架领域包括相互管路连接的一级小范围阻尼多级调节器、二级大范围阻尼多级调节器和单向馈能及能量回收系统,其中一级小范围阻尼多级调节器的出油口与单向馈能及能量回收系统的进油口通过进油管连接,单向馈能及能量回收系统的出油口与一级小范围阻尼多级调节器的进油口通过回油管连接,其中进油管上设置有节流阀,二级大范围阻尼多级调节器的两端管路并联设置在进油管上节流阀的两侧。其能够实现悬架系统阻尼孔工作数量的改变,实现悬架系统的阻尼在行程改变的情况下自适应调节,无需电力设备,通过机械结构即可实现阻尼自动调节;并实现阻尼减振耗能回收。
