Abstract

The invention relates to the field of variable gauges for rail vehicles, and discloses a wheel set for a variable gauge bogie and the bogie. The wheel set comprises wheels, an axle and variable gaugemechanisms, and the variable gauge mechanism comprises a fixed sleeve, a locking pin, a mitigation sleeve and an unlocking disc. The wheels are slidably disposed at two ends of the axle, and the variable gauge mechanisms are respectively disposed on the inner side axle of the wheel, and by pushing the unlocking disc to drive the locking pin to move upwards, the fixed sleeve is unlocked with the mitigation sleeve. Therefore, the wheels are locked or unlocked conveniently, to achieve the variable gauge. The wheel set variable gauge process is convenient and reliable.

Description

technical field [0001] The invention relates to the field of gauge changing of rail vehicles, in particular to a wheel set and a bogie used for 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 gauges of railways in various countries are different, which hinders cross-border railway transportation, a variable-gauge train is proposed. The distance between them is adapted to the gauge of other countries' railways. [0003] In the process of changing the gauge of the train, the distance between the wheels arranged at both ends of the axle will be adjusted. At this time, the wheels need to be moved in the axial direction of the axle. After the distance bet...
