The invention relates to the field of rail vehicle variable gauges and discloses a locking mechanism for a bearing outer sleeve and a locking rod. The inner circumference of the bearing outer sleeve is provided with a locking working face, a plurality of inner ring grooves are axially disposed at intervals in the locking working face, the locking working face is provided with a sliding groove axially passing through the plurality of inner ring grooves, the locking rod includes a locking head and an unlocking head, and the locking head is used for being clamped into the inner ring groove, to achieve locking. The unlocking head extends out of the sliding groove and can make the locking head away from the inner ring groove where the locking head is located under the action of an external force, to achieve unlocking. The invention also discloses the variable gauge wheel set. According to the locking mechanism, locking and unlocking can be achieved reliably, the operation is convenient, andthus variable gauges of a train can be achieved conveniently and reliably.
Description
technical field [0001] The invention relates to the field of gauge change of rail vehicles, in particular to a locking mechanism for a gauge change wheel set and a gauge change wheel set. Background technique [0002] With the rapid development of global economic integration, cross-border passenger and cargo transportation has grown rapidly in recent years. However, due to the different gauges of railways in various countries, it has caused serious obstacles to cross-border railway transportation. In order to solve the problem that the different gauges of railways in various countries hinder cross-border railway transportation, a variable-gauge bogie is proposed, that is, when the train travels on the railways of other countries, by changing the wheels on its own wheelset The distance between them is adapted to the gauge of other countries' railways. [0003] In the process of changing the gauge of the train, relative motion will occur between the wheels on the same wheel s...
