A bogie system, comprising a framework (1), walking wheels (2), horizontal wheels (3), a driving device, a traction device, a suspension device and a foundation brake device (4). The framework comprises a frame in the shape of the Chinese character "工" and four supporting legs (7). The frame in the shape of the Chinese character "工" comprises two cross beams (5) and a center beam (6) connected to the two cross beams (5). The four supporting legs (7) are respectively arranged on the bottom faces of two ends of the two cross beams (5). Two walking wheels (2) are provided and are respectively arranged on two sides of the center beam (6). The framework of the bogie system is a frame in the shape of the Chinese character "工", and the two walking wheels (2) are respectively arranged on two sides of the center beam (6) of the frame in the shape of the Chinese character "工", that is, the walking wheels (2) are mounted in an open manner. Thus, when the walking wheels (2) need to be replaced, a bogie does not need to be disassembled from a vehicle, only the walking wheels (2) need to be disengaged from a driving rail, and the replacing of the walking wheels (2) can be directly carried out on the bogie, such that the process of replacing wheels is simplified, the working efficiency is improved and the cost is controlled.
