Embodiment 1

[0043] This embodiment discloses a railway vehicle, which includes a variable-gauge bogie.

[0044] figure 1 It is a structural schematic diagram of the variable-gauge bogie of the present embodiment, figure 2 for figure 1 The schematic diagram of the top view, image 3 for figure 1 A schematic side view of the combined Figure 1-Figure 3 , the variable gauge bogie of the present embodiment comprises two wheelsets to form 1, four sets of axle positioning devices 2, a frame, a bolster to form 4, a set of braking device 5, two lower side bearings 6 and Two sets of central spring suspension damping devices 7 etc. are formed, wherein, the frame of the present embodiment comprises two side frames to form 3 .

[0045] Figure 4 It is a structural schematic diagram of the braking device of this embodiment, combined with Figure 4 In this embodiment, the braking device 5 adopts four sets of caliper braking units 51, and the caliper braking units 51 are assembled on the braking...

Embodiment 2

[0061] The difference between the second embodiment and the first embodiment is that the second embodiment does not set the clamping hoop 22, Figure 9 It is the structural intention of another implementation of the wheel axle positioning device of this embodiment, combining Figure 9 , in this case, the central angle of the first positioning opening is less than or equal to 180°, the bearing saddle 22 is connected to the side frame composition 3 of the frame on the same side through a flexible piece 26, and the flexible piece 26 can be in the form of a chain, a steel cable, etc. , has a certain amount of looseness. In this case, the bearing saddle 21 is not loaded and unloaded together with the wheel axle composition. When the wheel axle composition 1 is in place, the wheel axle composition 1 is placed within the correct range through the cooperation of the bearing saddle 21 and the positioning block 23.

Embodiment 3

[0063] Based on the above-mentioned railway vehicle with gauge-changing bogies, this embodiment also discloses a method of gauge-changing railway vehicles.

[0064] Figure 10 It is a schematic diagram of the system used by a method for changing the gauge of railway vehicles in this embodiment, combined with Figure 10 , the system used in a method for changing the gauge of railway vehicles in this embodiment includes a train system 100, an axle storage system 200, an unloading axle system 300, and a push system 400, wherein: the vehicle 110 in the train system 100 is equipped with the above-mentioned rapid The bogie 111 of the unloaded axle composition 1; the axle warehouse system 200 is a three-dimensional intelligent warehouse for classifying and storing the axle composition 1; the unloading axle composition 1 is unloaded from the vehicle 110 and transmitted to the axle warehouse system 200 for storage. Or take out the axle assembly 1 from the axle storage system 200, and ...

Abstract

The invention relates to a gauge-changeable bogie and a railway vehicle. The gauge-changeable bogie comprises wheel set assemblies and a framework, the two wheel set assemblies are oppositely arrangedon the framework in the longitudinal direction, each wheel set assembly comprises an axle, axle positioning devices are arranged at the two axial ends of each axle, and a first positioning opening isformed in the bottom of a bearing saddle of each axle positioning device; the axial end of each axle is arranged in the corresponding first positioning opening, a first positioning groove is formed in the top of each bearing saddle, a second positioning groove is formed in the side of each bearing saddle, positioning blocks are fixedly arranged on the framework, the positioning blocks and the bearing saddles are correspondingly arranged, and each positioning block is provided with a first positioning protrusion; and the first positioning protrusions of the positioning blocks can be embedded in the first positioning grooves of the corresponding bearing saddles, second positioning protrusions are arranged on side frames, and the second positioning protrusions can be embedded in the second positioning grooves of the corresponding bearing saddles. High-efficiency and high-reliability gauge-changeable railway transportation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, in particular to a variable-gauge bogie and a railway vehicle. 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. Solving the gap between different gauges The transport issue has major implications. [0003] In the prior art, the measures to solve the problem of railway intermodal transportation with different gauges mainly include unifying the line, transshipment, exchanging running parts and adopting variable-gauge bogies. , it needs to occupy a large space and manpower, and the track change efficiency is low. The method of unifying the track can fundamentally solve the problem of gauge differences, but the input cost is hig...
