The invention discloses a vehicle-mounted spare tire carrying and transporting device. The vehicle-mounted spare tire carrying and transporting device mainly comprises spare tires, a tire fixing disc,a tire swing rod, a rotating shaft support, lug ring supports, a shaft bracket support, a spare tire underframe, a hydraulic cylinder and a limiting mechanism; the spare tire underframe is fixed to avehicle chassis or a platform, and the shaft bracket support is fixed to the front end and the rear end of the spare tire underframe respectively; and the two lug ring supports are symmetrically arranged in the middle of the spare tire underframe, and one lug ring support is fixed to the edge of the rotating shaft support. The vehicle-mounted spare tire carrying and transporting device is reasonable in structural design, the two spare tires can be carried at the same time through a swing rod mechanism, a locomotive hydraulic system serves as a power source, automatic lifting of the side wallsof the spare tires is achieved, and the problem that the lifting height of a straight arm type spare tire lifting device is limited is solved; the fixing disc can carry multiple types of spare tires,so that the space utilization rate of a whole vehicle is increased; and the device is provided with the synchronous and stable limiting mechanism, so that the spare tires are firmly fixed and can adapt to a bumpy environment, and the problems of large spare tire, heavy weight, different hub sizes, complex driving environment and cumbersome loading and unloading of special equipment vehicles are solved.

    本发明公开了一种车载备胎携运装置,主要包括备胎、轮胎固定盘、轮胎摆杆、旋转轴支架、耳环支座、轴架支座、备胎底架、液压缸和限位机构,所述备胎底架固定于车辆底盘或平台上面,备胎底架前后端分别固定轴架支座,备胎底架中部对称设置两个耳环支座,旋转轴支架边缘固定一个耳环支座。本发明在结构上设计合理,通过摆杆机构,可同时携运两个备胎,以机车液压系统为动力源,实现备胎侧壁自动升降,解决直臂式备胎升降装置吊高有限问题;其固定盘可携运多型号备胎,提高了整车空间利用率;装置带有同步稳定的限位机构,使得备胎固定牢固且可以适应颠簸环境,解决特种装备车辆备胎大、质量重、轮毂尺寸不一、行车环境复杂、装卸烦琐的问题。
