The invention belongs to an amphibious vehicle spare tire and a sailing propulsion device in the technical field of amphibious vehicles. A servo motor (2-1) of the switching device (2) is connected with a screw rod (2-4), a connecting piece (2-3) is sleeved on the screw rod (2-4), a driving motor (2-5) is arranged at one end of the connecting piece (2-3), a connecting part (2-2) is connected with an upper positioning part (2-6) and a lower positioning part (2-7), the other end of the connecting piece (2-3) is clamped with the connecting part (2-2), and the screw rod (2-4) movably penetrates through the lower positioning part (2-7). And a propelling propeller (3-2) of the spare tire/sailing propelling device (3) is positioned on the inner ring of the tire (3-1). According to the amphibious vehicle spare tire and sailing propulsion device, the structure is simple, switching between the spare tire and the sailing propeller can be achieved, land operation of the vehicle is not affected when the spare tire is switched to the sailing propeller, the caster angle of the vehicle in water is increased when the sailing propeller is switched to the sailing propeller, meanwhile, water resistance is reduced, and the trafficability of the vehicle in water is improved.
本发明属于两栖车辆技术领域的两栖车辆备胎和航行推进装置。切换装置(2)的伺服电机(2‑1)连接丝杆(2‑4),丝杆(2‑4)上套装联结件(2‑3),联结件(2‑3)一端设置驱动电机(2‑5),连接部件(2‑2)连接上部定位部(2‑6)和下部定位部(2‑7),联接件(2‑3)另一端卡装连接部件(2‑2),丝杆(2‑4)活动穿过下部定位部(2‑7),备胎/航行推进装置(3)的推进螺旋桨(3‑2)位于轮胎(3‑1)内圈。本发明所述的两栖车辆备胎和航行推进装置,结构简单,能够实现备胎和航行推进器切换,切换为备胎时,不影响车辆在陆地行事,切换为推进器时增大车辆在水中的后倾角,同时减小水阻力,提高车辆在水中的通过性。
