The invention provides a novel double-electromagnetic-valve full-active suspension actuator. The novel double-electromagnetic-valve full-active suspension actuator comprises a shock absorber, a hydraulic valve block, a recovery electromagnetic valve and a compression electromagnetic valve. The hydraulic valve block is arranged at the cylinder bottom in a sealed mode and internally provided with a compression oil channel communicated with the lower cavity of the working cylinder and a recovery oil channel communicated with the upper cavity of the working cylinder, and the compression oil channel and the recovery oil channel are outwards connected with a power pump. The recovery electromagnetic valve is arranged on the outer wall of the oil storage cylinder, is communicated with the upper cavity and the oil storage cylinder, and is also provided with a recovery one-way valve communicated with the oil storage cylinder and the upper cavity; the compression electromagnetic valve is connected to the valve block and communicated with the lower cavity and the oil storage cylinder, and is further provided with a compression one-way valve communicated with the oil storage cylinder and the lower cavity. According to the novel double-electromagnetic-valve full-active suspension actuator, the structure is optimized, the occupied space of a chassis is reduced, the actuator has multiple working modes including a full-active mode, an active ADS mode and an ADS mode, full-active adjustment with higher jacking capacity and compression capacity can be achieved, the damping adjustment broadband in the ADS mode is increased, and the energy recovery function is achieved.

    本发明提供一种新型双电磁阀全主动悬架执行器,包括减振器、液压阀块、复原电磁阀、压缩电磁阀;液压阀块密封设置在缸底,内部具有连通工作缸下腔的压缩油道、连通工作缸上腔的复原油道,压缩油道和复原油道向外连接动力泵;复原电磁阀设置在贮油缸外壁并连通上腔和贮油缸,还带有连通贮油缸和上腔的复原单向阀;压缩电磁阀连接在阀块上并连通下腔和贮油缸,还带有连通贮油缸和下腔的压缩单向阀。该新型双电磁阀全主动悬架执行器优化了结构、减小底盘占用空间,具有全主动模式、主动ADS模式、ADS模式多种工作模式,能够实现更大顶升能力和压缩能力的全主动调节、增大ADS模式下的阻尼调节宽带、以及实现能量回收功能。
