The invention relates to the technical field of automobiles, in particular to an active shock absorber capable of reducing unsprung mass. 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 energy accumulator. The weight of the heaviest component, namely the electric hydraulic pump, on the active shock absorber is transferred into sprung mass, so that the influence of the active shock absorber on unsprung mass is reduced, in addition, the piston rod is connected with the suspension, and the unsprung mass can be greatly reduced in this way due to the fact that the piston rod only occupies a small part of the weight of the active shock absorber, and the service life of the active shock absorber is prolonged. Therefore, the comfort of the whole vehicle is improved.
本发明涉及汽车技术领域,具体的说是一种降低簧下质量的主动减振器。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,另一端与蓄能器连接。本发明将主动减振器上最重的部件即电动液压泵重量转移为簧载质量,从而降低主动减振器对簧下质量的影响,另外,活塞杆与悬架连接,由于活塞杆只占主动减振器重量的很小一部分,通过这种方式可以大大减小簧下质量,从而提高整车舒适性。
