The invention relates to the field of vehicle body posture adjusting active suspensions, in particular to a vehicle body posture adjusting active suspension actuator, a system and a control method, and the vehicle body posture adjusting active suspension actuator comprises a shock absorber, a hydraulic two-way pump, an energy accumulator and a fluid loop; the shock absorber comprises a cylinder body, a piston rod and a piston head, the piston rod and the piston head are assembled and then slidably installed in the cylinder body, and the cylinder body is divided into a rod cavity and a rodless cavity. The fluid loop comprises a first hydraulic pipeline and a second hydraulic pipeline, the first hydraulic pipeline is communicated between the rod cavity and the hydraulic two-way pump, and the second hydraulic pipeline is communicated between the rodless cavity and the hydraulic two-way pump; a first hydraulic branch and a second hydraulic branch are sequentially connected to the fluid loop in parallel in the direction from the shock absorber to the hydraulic two-way pump. The whole device has the advantages that active output force can be automatically changed in real time according to changes of external conditions and environments, ideal suspension performance can be obtained under various working conditions, and comfort and operation stability can be both considered.

    本发明涉及车身姿态调节主动悬架领域,特别涉及了一种车身姿态调节主动悬架作动器、系统及控制方法,车身姿态调节主动悬架作动器包括减振器、液压双向泵、蓄能器及流体回路;减振器包括缸体、活塞杆、活塞头,活塞杆、活塞头组装后可滑动的安装在缸体内,并将缸体分隔为有杆腔和无杆腔;流体回路包括第一液压管线、第二液压管线,第一液压管线连通于有杆腔与液压双向泵之间,第二液压管线连通于无杆腔与液压双向泵之间;流体回路上自减振器向液压双向泵的方向上依次并联有第一液压支路、第二液压支路;整个装置的优点在于可以根据外界条件及环境的变化自动实时地改变主动输出力,在各种工况下都获得理想的悬架性能,能够兼顾舒适性和操稳性。
