[0002] As a special traffic mode suitable for large slope and complex road conditions, the stability of the gear and rack tooth engagement of the mountain rack railway directly relates to the driving safety and riding comfort, and is a core technical link to ensure the operation of the line.

[0003] At present, the tooth entering device of the existing mountain rack railway generally adopts an active driving mode, that is, a driving mechanism is additionally arranged to drive the gear to rotate to realize the engagement with the rack. Although this kind of device can complete the basic tooth entering function, it has significant defects: on the one hand, the additional driving mechanism leads to a complex structure and high manufacturing cost of the device, and the operation and maintenance space is limited in the mountain environment and the working conditions are harsh, which further increases the difficulty of equipment maintenance and operation and maintenance cost; on the other hand, the traditional tooth entering structure lacks the self-adaptive adjustment capability of the gear and rack spacing, and a rigid impact is easily generated in the engagement moment, which not only aggravates the wear of the gear and rack, shortens the service life of the parts, but also affects the driving stability.
