The invention relates to the field of rail vehicle variable gauges, and discloses a dust cover of a locking mechanism for a gauge-changeable wheel set and the gauge-changeable wheel set. The dust cover comprises an annular cover body and check rings arranged at two axial ends of the annular cover body, and at least one pair of electric brushes are arranged on an inner wall of the annular cover body; an outer wall of an installation sleeve of the locking mechanism is provided with chips in one-to-one correspondence with the electric brushes; the installation sleeve is provided with a pair of annular installation grooves surrounding the periphery of the installation sleeve at intervals in the axial direction of the installation sleeve; the inner circumferences of the check rings are installed in the annular installation grooves respectively, and the chips and the electric brushes are in friction to form electric connection through rotation of the installation sleeve. According to the dust cover, electric connection is formed through friction between the chips and the electric brushes, so that a power supply circuit is formed between the locking mechanism and an external power supplyunit; locking and unlocking can be directly achieved without the help of external equipment, so ground gauge changing facilities become relatively simple; gauge changing signals are output by a vehicle control system, and the reliability and gauge changing efficiency of gauge changing actions are improved.
Description
technical field [0001] The invention relates to the technical field of gauge change of rail vehicles, in particular to a dust cover of a locking mechanism for a gauge change wheel set and a gauge change wheel set. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, which can run continuously between tracks of different gauges. [0003] However, in the existing track changing structure, especially the locking mechanism is passive, and the track changing action can only be completed with the help of external auxiliary facilities, which has low efficiency and high investment cost. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at ...
