Problems solved by technology

[0003] The variable gauge bogie in Spain adopts the form of independent wheelset, which needs to set up 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 installation space of the brake device or other components, increasing the cost and reducing the service life

Abstract

The invention relates to the field of railway vehicle bogies and discloses a trailer gauge-changeable bogie used for a railway vehicle. The trailer gauge-changeable bogie comprises a framework. The framework comprises a pair of side beams arranged in parallel and a pair of crossbeams connected between the pair of the side beams and arranged in parallel, a gauge-changeable wheel set is arranged onthe outer side of each of the pair of the crossbeams, and each gauge-changeable wheel set comprises an axle, wheels and locking mechanisms. Axle box bodies are arranged at the two ends of each of thepair of the side beams, the two ends of each axle extend into the corresponding axle box bodies, the wheels are installed on the axles and connected with the axles through splines, the locking mechanisms are arranged on the outer sides of the wheels, located in the axle box bodies, connected with the wheels and used for transversely locking and unlocking the wheels, and therefore transverse gaugeswitchover of the wheels is achieved. The structures of existing vehicles are slightly changed, bogies / wheel sets of the existing vehicles can be conveniently transformed in batches, the universalityand reliability of the gauge-changeable bogie and the transport efficiency of a whole vehicle are improved, and reliable stopping and braking can be achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a trailer-gauge variable-gauge bogie for rail vehicles. 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 installation space of the brake devi...
