The invention provides a novel double-electromagnetic-valve shock absorber which comprises an oil storage cylinder, a middle cylinder, a working cylinder and a piston rod and further comprises a recovery valve assembly, a compression valve assembly, a recovery electromagnetic valve and a compression electromagnetic valve. The rebuilt valve assembly is connected to the lower end of the piston rod to divide the working cylinder into an upper cavity and a lower cavity; the compression valve assembly is arranged at the bottom end of the working cylinder to communicate the lower cavity with the oil storage cylinder; the restoring electromagnetic valve is connected to the outer side of the oil storage cylinder, and the upper cavity is communicated with the oil storage cylinder; the compression electromagnetic valve is arranged at the bottom of the oil storage cylinder to communicate the lower cavity with the oil storage cylinder; when the piston rod moves upwards, part of oil in the upper cavity flows into the oil storage cavity through the recovery electromagnetic valve, and part flows into the lower cavity through the recovery valve assembly. When the piston rod moves downwards, part of oil in the lower cavity flows into the oil storage cylinder through the compression electromagnetic valve, part flows into the oil storage cylinder through the compression valve assembly, and part flows into the upper cavity through the rebuilt valve. According to the novel double-electromagnetic-valve shock absorber, damping force adjustment in a large range can be achieved under the condition that the occupied chassis space is small.

    本发明提供一种新型双电磁阀减振器,包括贮油缸、中间缸、工作缸和活塞杆,还包括复原阀组件、压缩阀组件、复原电磁阀、压缩电磁阀;复原阀组件连接在活塞杆的下端将工作缸分隔为上腔和下腔,压缩阀组件设置在工作缸的底端将下腔与贮油缸连通;复原电磁阀连接在贮油缸的外侧,将上腔与贮油缸连通;压缩电磁阀设置在贮油缸的底部,将下腔与贮油缸连通;活塞杆上行时上腔中部分油液经过复原电磁阀流入贮油腔,部分经过复原阀组件流入下腔;活塞杆下行时下腔部分油液经过压缩电磁阀流入贮油缸,部分经过压缩阀组件流入贮油缸,部分经过复原阀流入上腔。该新型双电磁阀减振器,能够占用较小底盘空间较小的情况下,实现了较大范围的阻尼力调节。
