Embodiment 1
[0059] This embodiment discloses a railway vehicle, which includes a variable-gauge bogie.
[0060] 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 wheel shafts 1, four sets of wheel shaft positioning devices 2, a frame, a bolster composition 4, a set of braking devices 5, two lower side bearings 6 and two Cover the central spring suspension damping device 7 etc. to form, and wherein, the framework of the present embodiment comprises two side frames and forms 3.
[0061] 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 ...
Embodiment 2
[0077] 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 21 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
[0079] Based on the above-mentioned railway vehicle with gauge-changing bogies, this embodiment also discloses a method of gauge-changing railway vehicles.
[0080] 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 ...
