The invention relates to a device with active lifting and automatic damping throwing. The device comprises a primary suspension, an upper connecting rod, a primary left rocking arm, a primary right rocking arm, a secondary left rocking arm, a secondary right rocking arm, a secondary suspension, a lower connecting rod, and an electrohydraulic actuator, wherein the electrohydraulic actuator is connected with the primary left rocking arm and the primary right rocking arm. A connecting rod mechanism is used for realizing the up-down movement of the secondary suspension by the stretching and retraction of a piston rod of the electrohydraulic actuator and under the restriction of the primary left rocking arm, the primary right rocking arm, the secondary left rocking arm, and the secondary rightrocking arm; by the restriction of the lower connecting rod to the secondary left rocking arm and the secondary right rocking arm, the secondary suspension is guaranteed to be always in a horizontal state; a damper on the electrohydraulic actuator can be used for limiting hydraulic pressure to drop too quickly, and can be used for performing damping deceleration when a load is thrown; and the connecting rod device is simple in structure, and is safe and reliable.

    本发明涉及一种具有主动提升和自动阻尼投放的装置,包括一级悬挂、上连杆、一级左摇臂、一级右摇臂、二级左摇臂、二级右摇臂、二级悬挂、下连杆和电液作动器,电液作动器与一级左摇臂和一级右摇臂连接,连杆机构通过电液作动器的活塞杆伸缩和在一级左摇臂、一级左摇臂、一级右摇臂、二级左摇臂、二级右摇臂的约束下,实现二级悬挂的上下移动,通过下连杆对二级左摇臂和二级右摇臂的约束,保证二级悬挂始终处于水平状态;电液作动器上的阻尼器,可以限制液压下降过快,可以对负载投放时进行阻尼减速;本连杆装置结构简单,安全可靠。
