Abstract

The invention relates to the field of rail vehicle variable gauges, and discloses a movable disc assembly for a variable gauge wheel set; the movable disc assembly comprises a movable disc and a bearing, and the movable disc is provided with a central through hole and a connecting hole located outside the central through hole; an outer ring of the bearing is fastened in the central through hole, and an inner ring of the bearing is used for being fixedly arranged on an outer hub of a wheel in a sleeving mode. The movable disc assembly is simple in structure, and is capable of being fastened towheels and small in an occupied wheel space; a transverse driving mechanism pushes or pulls the movable disc to drive the wheels to move, and gauge changing of the wheels is achieved; by using the movable disc assembly, the transmission torque is large, the reliability is high, the gauge changing reliability is improved, and the gauge changing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of track gauge change for rail vehicles, in particular to a moving disc assembly used for track gauge wheel sets. 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, the existing track-changing structures are all passive, and the track-changing action of the wheels can only be completed with the help of external auxiliary facilities, and the efficiency is low. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related ...
