The undercarriage comprises a supporting arm, a buffer supporting column outer barrel, a buffer supporting column piston rod, a folding and unfolding device, the frame and a multi-connecting-rod mechanism, the buffer supporting column piston rod and the folding and unfolding device are connected with the buffer supporting column outer barrel, the frame is connected with the outer end of the buffer supporting column piston rod, and the upper end of the buffer supporting column outer barrel is hinged to a D installation point at the lower end of the supporting arm; one end of the multi-connecting-rod mechanism is hinged to an E mounting point at the lower end of the supporting arm, the other end of the multi-connecting-rod mechanism is hinged to the frame, and a C mounting point can rotate around a D mounting point; when the undercarriage starts to be folded, the folding and unfolding device retracts and drives the buffer supporting column outer cylinder to rotate, so that the multi-connecting-rod mechanism rotates and drives the frame to rotate and fold. According to the undercarriage with the frame capable of being folded and unfolded in a follow-up rotating mode, the multi-connecting-rod mechanism is driven by the folding and unfolding movement of the folding and unfolding device to drive the frame to rotate, so that the undercarriage is folded into the undercarriage cabin in the most suitable contour, and the space of the undercarriage storage cabin is compact.

    本发明公开一种车架可随动旋转收放的起落架,包括支臂、缓冲支柱外筒、与缓冲支柱外筒相连的缓冲支柱活塞杆和收放装置、与缓冲支柱活塞杆外端部相连的车架、以及多连杆机构,缓冲支柱外筒上端与支臂下端的D安装点铰接;所述多连杆机构一端与支臂下端的E安装点铰接,另一端与车架铰接,C安装点可绕D安装点转动;当起落架开始收起,收放装置缩回且驱动缓冲支柱外筒转动,使得多连杆机构转动并驱动车架旋转折叠。本发明的车架可随动旋转收放的起落架,通过收放装置的收放运动带动多连杆机构驱动车架旋转使起落架以最适宜轮廓收进起落架舱,使得起落架收藏舱空间紧凑。
