The invention relates to the technical field of automobiles, in particular to an active shock absorber. Comprising an active shock absorber body, an electric hydraulic pump, an energy accumulator, a compression cavity oil way and a recovery cavity oil way. The active shock absorber body is connected with a vehicle body and a suspension; one end of the compression cavity oil way is connected with a compression cavity of the active shock absorber body, and the other end is connected with the electric hydraulic pump; one end of the recovery cavity oil way is connected with a recovery cavity of the active shock absorber body, and the other end of the recovery cavity oil way is connected with the electric hydraulic pump and the energy accumulator. The defect that the response bandwidth of the active shock absorber is insufficient can be overcome, the high-frequency-band damping force which cannot be responded by the active shock absorber is reduced, and the high-frequency vibration comfort of the whole vehicle is improved.

    本发明涉及汽车技术领域,具体的说是一种主动减振器。包括主动减振器本体、电动液压泵、蓄能器、压缩腔油路和复原腔油路;所述主动减振器本体与车身和悬架连接;所述压缩腔油路一端与主动减振器本体的压缩腔连接,另一端与电动液压泵连接;所述复原腔油路的一端与主动减振器本体的复原腔连接,另一端与电动液压泵和蓄能器连接。本发明可以弥补主动减振器响应带宽不足的缺点,降低主动减振器无法响应的高频段阻尼力,提高整车高频振动舒适性。
