The explosion-proof rubber-tyred vehicle mainly works in flammable and explosive environments such as gas, coal dust and the like, has explosion-proof performance, and meets the requirements of technical inspection standards of explosion-proof diesel engines for coal mines. However, in the actual production process of the underground coal mine, the situations of narrow roadway width, multiple turns and the like exist objectively, and due to the design problems (large volume, long length and the like), the common explosion-proof trackless rubber-tyred vehicle is difficult to adapt to the transportation environment with narrow width and multiple turns, so that the problem of unsmooth underground transportation can be caused, and the efficiency and safety of underground production are seriously influenced. From the analysis of principle, the split rubber-tyred vehicle (the rubber-tyred vehicle formed by the hinged connection of the front vehicle body and the rear vehicle body) should have good applicability to the transportation environment with multiple turns, but in the actual production, because the design of the hinge device between the vehicle bodies is unreasonable, the effect of the rubber-tyred vehicle in the actual use process is very unsatisfactory. Therefore, it is very important to design a vehicle body hinge device with a completely new structure.
