Abstract

The invention relates to the field of rail vehicle gauge changing, and discloses a traction electromagnet for a gauge-changeable wheel set and a locking mechanism for the gauge-changeable wheel set. The traction electromagnet comprises a shell, a traction coil and a movable iron core; the traction coil is arranged in the shell; one end of the movable iron core penetrates through the traction coil;the movable iron core is controlled to move by the on-off of the traction coil; the other end of the movable iron core stretches out of the shell and is fixedly connected with a locking pin; the movable iron core can drive the locking pin to stretch into or leave a locking hole in a wheel hub, and the traction electromagnet further comprises at least one sucker coil and a lockpin matched with each sucker coil. The traction electromagnet can actively stretch out and withdraw, and wheel locking and unlocking can be directly achieved without the help of external equipment; and the reliability and the gauge changing efficiency of the gauge changing action are improved.

Description

technical field [0001] The invention relates to the technical field of gauge change of rail vehicles, in particular to a traction electromagnet for a gauge change wheel set and a locking mechanism for 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...
