Abstract

The invention relates to the field of vehicle variable gauge, and provides a variable gauge bogie, which comprises a frame, two pairs of variable gauge wheel pairs arranged on both transverse sides ofthe frame, each pair of variable gauge wheel pair comprises a axle, wheels arranged at both ends of the axle, and a transmission mechanism matched to the corresponding wheels; a driving motor corresponding to the wheels is arranged in the longitudinal of the frame. An output shaft of the driving motor is connected with a driving gear through a pair of bevel gear wheel set. An output shaft of thedriving motor is coaxially arranged with a first bevel gear in the bevel gear wheel set, the second bevel gear in the bevel gear wheel set is coaxial with the driving gear, the first bevel gear is meshed with the second bevel gear in the vertical direction, and a driven gear is fixed in the periphery of the transmission mechanism. The driven gear is meshed with the driving gear. Each wheel is driven by a corresponding driving motor and rotates independently of the axle. The bogie can improve the running efficiency of a wheel pair on different tracks, ensure the running safety of a vehicle andimprove the dynamic performance of a variable gauge train.

Description

technical field [0001] The invention relates to the technical field of gauge changing of rail vehicles, in particular to a gauge changing bogie. 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 a train travels on a railway in another country, it changes the distance between the wheels on its own wheelset The distance between them is adapted to the gauge of other countries' railways. [0003] However, the structure of the traditional wheel set is affected by the serpentine motion performance, the critical speed is limited, the structu...
