A wheelset locking mechanism for a variable gauge bogie

Abstract

The invention discloses a gauge-changeable bogie wheel set locking mechanism. The gauge-changeable bogie wheel set locking mechanism comprises a lock sleeve, key covers, keys, an unlocking guide shaft, a trapezoidal lock arm, a locking spring and an unlocking roller assembly; guide holes and key grooves are formed in the lock sleeve; the guide holes are matched with locking arms and end surface driving arms in shape; the key cover is arranged in key cover mounting threaded holes in the lock sleeve through bolts; lock blocks are arranged on the keys, are matched with locking grooves in the locking arms in shape and extend into the key grooves; the unlocking guide shaft is formed by welding an unlocking guide shaft rod and unlocking roller bases; and the unlocking guide shaft rod is in clearance fit with an end cover locking guide hole. The wheel pair locking mechanism is used for unlocking and locking in the gauge-changeable process.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and relates to gauge change technology, in particular to a wheel pair locking mechanism of a variable gauge bogie. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, my country has carried out larger-scale, higher-level, and deeper regional cooperation with countries along the route, and is committed to building an all-round interconnection network. Among them, railway transportation has increasingly become the most important part of the Eurasian road. However, railways with different gauge specifications in different countries and regions have brought many restrictions to the development of international intermodal transport. [0003] Aiming at railways with different gauges, domestic and foreign are committed to researching a variable-gauge bogie, which can adapt to railways with different gauges by changing the wheel set wheelbase of the variable-g...
