Problems solved by technology

[0003] The variable gauge bogie in Spain adopts the form of independent wheel sets, which requires additional guide structure, which is complex in structure; the variable gauge bogie in Japan sets the sliding mechanism on the inner side of the wheel, and adds an outer wheel to the outside of the axle. The sleeve is equivalent to increasing the diameter of the axle, thus limiting the design space of the motor and gearbox, and putting forward higher requirements for the gearbox bearings, increasing the cost and reducing the service life

Abstract

The invention relates to the technical field of rail vehicle gauge-changeable, and discloses a gauge-changeable wheel set. The gauge-changeable wheel set comprises vehicle wheels, an axle and lockingmechanisms. The vehicle wheels are arranged at both ends of the axle and connected with the axle through splines. The locking mechanisms are separately arranged on the outer sides of the vehicle wheels and located in axle box bodies at both ends of the axle, and the locking mechanisms are connected with the vehicle wheels and used for locking and unlocking the vehicle wheels so as to achieve gaugechange of the vehicle wheels. The gauge-changeable wheel set is simple in structure, modification to the structure of an existing vehicle is little, batch transformation of the existing vehicle is facilitated, and the universality and reliability of the gauge-changeable wheel set are improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle gauge change, in particular to a variable gauge wheel set. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, which can run continuously between tracks of different gauges. [0003] The variable gauge bogie in Spain adopts the form of independent wheel sets, which requires additional guide structure, which is complex in structure; the variable gauge bogie in Japan sets the sliding mechanism on the inner side of the wheel, and adds an outer wheel to the outside of the axle. The sleeve is equivalent to increasing the diameter of the axle, thereby limiting the design space of the motor and the gearbox, and putting for...
