The invention provides a double-valve shock absorber and a suspension system.The shock absorber comprises a liquid storage barrel and a piston rod, an energy storage device cavity and a working cylinder are arranged in the liquid storage barrel, the interior of the working cylinder is divided into a recovery cavity and a compression cavity through a piston on the piston rod, and a safety valve is arranged on the piston; a bottom valve is arranged on the working cylinder; a rebuilt valve and a compression valve are arranged outside the liquid storage cylinder, the rebuilt valve comprises a first one-way electromagnetic valve and a rebuilt oil cavity, the rebuilt oil cavity is communicated with a rebuilt cavity, the rebuilt oil cavity is communicated with the energy storage device cavity through the first one-way electromagnetic valve, the compression valve comprises a second one-way electromagnetic valve and a compressed oil cavity, and the compressed oil cavity is communicated with the energy storage device cavity. The compressed oil liquid cavity is communicated with the recovery cavity through a second one-way electromagnetic valve, and the recovery oil liquid cavity is communicated with the compressed oil liquid cavity through conveying equipment. Stepless damping adjustment can be achieved, the wheels can be actively lifted, damping can be adjusted in real time according to different driving conditions when a vehicle is applied, the height of a vehicle body is adjustable, and the driving experience is optimized.

    本发明提出了一种双阀减振器及悬架系统,减振器包括贮液筒和活塞杆,贮液筒内设有储能器腔和工作缸,工作缸内部通过活塞杆上的活塞分为复原腔和压缩腔,活塞上设有安全阀;工作缸上设有底阀;贮液筒外分别设有复原阀和压缩阀,复原阀包括第一单向电磁阀和复原油液腔,复原油液腔与复原腔连通,复原油液腔通过第一单向电磁阀与储能器腔连通,压缩阀包括第二单向电磁阀和压缩油液腔,压缩油液腔与储能器腔连通,压缩油液腔通过第二单向电磁阀与复原腔连通,复原油液腔和压缩油液腔通过输送设备连通。本发明可实现无级调节阻尼且能够主动升降车轮,车辆应用本发明可根据不同行驶状况实时调节阻尼,且车辆车身高度可调,优化驾驶体验。
