A lock key assembly applied to variable gauge bogie

Abstract

The invention belongs to the technical field of bogie systems and particularly relates to a key component applied to a bogie with variable gauges. The key component comprises a locking piece and an unlocking piece, wherein the locking piece comprises a lock rod; the lock rod is in slip connection with an axle box, the upper part of the lock rod is positioned in the axle box, and the lower part ofthe lock rod extends from the axle box to the outside of the axle box; and the unlocking piece comprises a base frame which is V-shaped, and two ends of the base frame are connected with the lower endof the lock rod. Aiming at the problem of low transport efficiency when a train passes through railways with different gauges, the invention provides the unlocking piece, the unlocking piece is applied to the bogie, and wheels are adjusted relative to an axle in an axial direction and then can be locked and unlocked, so that the wheel gauge between two wheels of the bogie can be transformed so asto adapt to railways with different gauges. The railway transport developing the silk road economic belt has the problem of non-uniform railway gauges, so that the development of design for the bogiesystems with variable gauges has very important and profound significance.

Description

Technical field [0001] The invention belongs to the technical field of bogie systems, and specifically relates to a key assembly applied to a gauge-changing bogie. Background technique [0002] Due to historical reasons, railways in different countries and regions have adopted different gauge specifications. [0003] At present, there are two options to choose from when the train passes through railways with different gauge specifications. The first method is to transfer the cargo box, that is, the cargo box is hoisted from the train of one gauge specification to the train of another gauge specification; the other is the method of replacing the bogie, that is, the train is lifted up and suspended by the support device, and then the The bogie of one gauge specification is removed, and the bogie of another gauge specification is installed. The inefficiency of these two modes of transport has brought many restrictions on the development of international combined transport. Summary ...
