Abstract: In this paper, according to the conditions of the underground roadway and the characteristics of the typical work vehicle demand of the underground maintenance team, the design of the underground explosion-proof trackless rubber tyred vehicle is studied. By comparing the structure and traffic ability of the integrated and articulated explosion-proof trackless rubber tyred vehicles, it is determined that the design vehicle adopts the integrated structure, and the overall scheme design and the hard point parameters of the vehicle design are given. According to the requirements of the overall design scheme, the key systems such as the power system, transmission system, brake hydraulic system and hydraulic interconnected suspension of the trackless rubber tyred vehicle are designed and calculated, and the core components of each system are selected according to the calculation results. The explosion-proof trackless rubber tyred vehicle researched and designed in this scheme has compact structure and good power performance, can adapt to various working conditions in the coal mine, and has good comfort, and solves the vehicle demand of the underground maintenance team.
