The invention relates to an inverted single-cylinder type cylindrical linear motor active suspension. The inverted single-cylinder type cylindrical linear motor active suspension actuator comprises a cylindrical linear motor type actuator assembly, an inverted single-cylinder type damper assembly and a spiral spring assembly. The cylindrical linear motor type actuator assembly comprises a primary assembly with a through hole in a specific shape and a secondary assembly installed in association with the primary assembly, the primary assembly comprises a winding iron core and a primary outer cylinder, and the primary iron core is of a circular ring structure; and the secondary assembly comprises permanent magnets and magnetic conducting rings, the permanent magnets and the magnetic conducting rings are sequentially and alternately installed on the side face of a damper outer cylinder, the magnetic pole direction of each permanent magnet is parallel to the central axis of a damper, and the permanent magnets are arranged in the mode that polarities are opposite. According to the inverted single-cylinder type cylindrical linear motor active suspension, the mounting space is saved, the structural complexity is reduced, the control force is generated for active control, and the suspension performance is improved; and the Fail-Safe (failure protection) characteristic is realized, the basic mechanical structure is reserved, the suspension can still work normally after a motor fails, and the operation stability and the running stability of a vehicle are improved.

    本发明涉及一种倒置单筒式圆筒直线电机主动悬架,包括圆筒直线电机式作动器组件、倒置单筒式阻尼器组件和螺旋弹簧组件。圆筒直线电机式作动器组件为具有特定形状的通孔的初级组件和与初级关联安装的次级装组件,初级组件包括有绕组铁芯和初级外筒,初级铁芯结构为圆环状;次级组件包括永磁体、导磁环,永磁体与导磁环依次交替安装在阻尼器外筒侧面,且每个永磁体磁极方向与阻尼器中心轴线平行,布置方式为极性相对。本发明节省安装空间、降低结构复杂性的同时,又产生控制力进行主动控制,改善悬架性能,同时具有Fail‑Safe(失效保护)特性,保留了基本的机械结构,确保保障电机失效后,悬架仍能正常工作,提高了车辆操作稳定性和行驶平稳性。
