The invention relates to the technical field of dune buggies, in particular to a damping connecting structure of a dune buggy, which comprises a frame, a suspension and a damping device, the suspension is hinged to the frame, the damping device is arranged between the suspension and the frame, one end of the damping device is hinged to the suspension, and the other end of the damping device is hinged to the frame; the damping device comprises an inner rod, an outer rod and a piston; the piston is fixed with the inner rod, so that a first floating oil cavity is formed between the piston and the first end of the first channel; the protection piece is fixed with the inner rod and is in sliding sealing fit with the outer rod along the axial direction; a closed second floating oil cavity is formed in the protection piece and communicates with the first floating oil cavity through the gap. The elastic piece is used for providing elastic force so that the inner rod and the outer rod tend to be far away from each other in the axial direction; the flowing of the lubricating oil does not need extra power, and the acting force generated by the damping device in the damping process is partially converted into energy for pushing the lubricating oil to flow.

    本申请涉及沙滩车技术领域,具体涉及一种沙滩车的减震连接结构,包括车架、悬架和减震装置;所述悬架铰接于车架,所述减震装置设于悬架和车架之间,其一端与悬架相铰接,另一端与车架铰接;所述减震装置包括包括内杆、外杆、活塞;活塞与内杆相固定,以使活塞与第一通道的第一端之间形成第一浮动油腔;防护件与内杆相固定,并与外杆沿轴向滑动密封配合;所述防护件形成有封闭的第二浮动油腔,所述第二浮动油腔通过间隙与第一浮动油腔连通;弹性件用于提供弹性力以使内杆和外杆具有沿轴向相互远离的趋势;润滑油的流动无需额外提供动力,而是将减震装置在减震过程中所产生的作用力部分地转化为推动润滑油流动的能量。
