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.
