AI Technical Summary

Problems solved by technology

The wear of the wheel tread is limited, which greatly shortens the life of the wheel, and the cost of the whole life cycle of the vehicle is high
[0004] If the running gear fails or the wear of the wheel diameter exceeds the limit, the wheel set needs to be disassembled, replaced or repaired. The disassembly process is cumbersome, the cost is high, and the maintainability is poor.

Abstract

The invention provides a running gear structure and a gear vehicle wheel set, and belongs to the field of rail transit vehicles. The running gear structure comprises a first half ring gear, a second half ring gear and a gear hub; the gear hub is provided with a first mounting member, and the second half ring gear and the first half ring gear are provided with second mounting members respectively;the first half ring gear and the second half ring gear are fixed on the gear hub to be combined into an integral gear; the axis of the gear hub is further provided with a mounting through hole used for cooperating with an axle. The running gear structure and the gear vehicle wheel set have the advantages that a plurality of split ring gear sets with different pitch diameters can be predesigned, and after wheel running abrasion reaches the meshing tolerance limitation of a running gear and rack, another split ring gear set with an adaptive pitch circle replaces the corresponding split gear set,so that the wheel service life can be prolonged by about 4 times, and the economical efficiency of vehicle use is improved.

Description

technical field [0001] The invention relates to the field of rail transit vehicles, in particular to a traveling gear structure and a gear vehicle wheel set. Background technique [0002] The running gears on the wheel sets of existing rack railway vehicles at home and abroad are almost all integral gears, which are installed in the middle of the wheel set through interference or bolts. In the assembly sequence, the running gear must be installed first, then the middle part of the axle shaft, and finally the wheels at both ends. The wheels are press-fitted onto the axles with interference, requiring specific press-fitting equipment and complex processes. [0003] During the operation of the rack vehicle, the wheels on both sides have tread wear, and the diameter of the wheel becomes smaller accordingly. At the same time, the wheel and the running gear are installed on the same axis, and the meshing relationship between the gear and the rack will change with the diameter of...
