The invention discloses a suspension mechanism of a wheel type lunar rover. The suspension mechanism comprises a rover body and wheels, wherein the rover body and the wheels are connected through a lower cross arm; and a four-connecting-rod supporting mechanism is connected between the middle of the rover body and the wheels and is of a bilateral symmetry structure. The four-connecting-rod supporting mechanism comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, the four connecting rods are hinged to form a rhombus structure, and a shock absorber is arranged on the four-connecting-rod supporting mechanism and used for adjusting the vertical deformation positions of the connecting rods. The dual-connecting-rod symmetrical arrangementstiffness-adjustable suspension structure is driven by ascrew rod, so that the wheeled vehicle has the functions of heeling resistance, static vehicle height adjustment, dynamic vehicle posture adjustment and large-range ground height adjustment which can be realized by the hydro-pneumatic spring.

    本发明公开了一种轮式月球车的悬架机构,包括车体和车轮,所述车体和车轮之间通过下横臂连接,包括车体中间部位与车轮之间连接有四连杆支撑机构,所述四连杆支撑机构互为左右对称结构,所述四连杆支撑机构包括第一连杆、第二连杆第三连杆和第四连杆,四个所述连杆铰接互为菱形结构,所述四连杆支撑机构上设置有减振器用以调整连杆垂直的形变位置,本发明通过螺杆驱动双连杆对称布置式刚度可调悬架结构,使得轮式车辆具有可实现油气弹簧所能实现的抗侧倾、静态车高调节、动态车姿调节,大范围的距地高调节功能。
