Problems solved by technology

[0004] Due to the heavy weight of the half-frame and the wheels, and for the power bogie, the half-frame is also equipped with a relatively heavy traction motor, so the requirements for the cooperation between the frame and the ground track changing device are relatively high, and the ground changer is required. The rail device provides enough driving force to push the semi-frame to move, and the contact wear between the frame and the ground rail changing device is also relatively serious

Embodiment 1

[0054] This embodiment provides a bogie suitable for a rail vehicle, enabling the rail vehicle to switch between tracks of different gauges. figure 1 It is a schematic structural diagram of the bogie provided in Embodiment 1 of the present application, figure 2 It is a cross-sectional view of the connection between the wheel set and the axle box provided in Embodiment 1 of the present application. Such as figure 1 with figure 2 As shown, the bogie includes: a frame 1 , an axle box 2 , a wheel set 3 , a locking device 4 and an unlocking device 5 . Wherein, the frame 1 may be an "H"-shaped structure, including two longitudinal beams parallel to each other and extending along the longitudinal direction, and a cross beam spanning between the middle parts of the two longitudinal beams.

[0055] The axle box 2 is connected to the frame 1 through a series of suspensions. Specifically, there are two axle boxes 2, each of which is connected to the end of the longitudinal beam thr...

Embodiment 2

[0095] This embodiment optimizes the implementation of the bogie on the basis of the above embodiments.

[0096] The driving force for the above-mentioned relief plate 42 to move in the first direction can be provided by the track changing device on the ground, or by a driving mechanism arranged on the frame. This embodiment provides a method provided by a ground track changing device.

[0097] Such as figure 2 As shown, the unlocking device 5 can be used to cooperate with the ground track changing device to apply a thrust in the first direction to the relief plate 42 to push the relief plate 42 to move in the first direction.

[0098] Figure 16 It is a schematic structural diagram of the unlocking device provided in Embodiment 2 of the present application. Such as Figure 16 As shown, the unlocking device 5 includes: a first push rod 51 and a second push rod 52 . Wherein, the first push rod 51 extends along the vertical direction, and a first guiding inclined surface i...

Embodiment 3

[0121] This embodiment provides a ground track changing device, which is used to drive the above-mentioned wheels 32 to move in the axial direction, and to drive the unlocking device 5 to act.

[0122] Figure 22 It is a schematic structural diagram of the ground track changing device provided in Embodiment 3 of the present application. Such as Figure 22 As shown, the ground track changing device is arranged between the first track 61 and the second track 62 , assuming that the gauge of the first track 61 is smaller than that of the second track 62 .

[0123] The ground track changing device includes: guide rail 71 and unlocking rail 72 . Wherein, the guide rail 71 is used to apply a driving force to the wheel 32 to make the wheel 32 move toward or move toward each other along the axial direction. The unlocking rail 72 is used to support the axle box 2 , and is also used to apply a driving force to the unlocking device 5 , prompting the unlocking device 5 to act, and then ...

Abstract

Embodiments of the present application provide a bogie and a rail vehicle, wherein the bogie includes: a frame; an axle box; an axle; a wheel, which is arranged on the axle and can move in an axial direction; At least two groups of locking grooves are arranged; a positioning disc, which is arranged on the axle and rotates synchronously with the axle; a clamp; two clamp claws arranged symmetrically; the clamp claws are connected with the positioning disc through a pin shaft; The upper part rotates synchronously with the positioning disc; the release disc moves in the first direction to exert force on the jaws, so that the jaws rotate until they come out of the locking groove; the release disc moves in the second direction to exert force on the jaws to rotate the jaws to The locking slot is inserted; the unlocking device is arranged on the axle box or the frame, and is used for applying an axial thrust to the relief disc, so that the relief disc can move in the first direction. The bogie and the rail vehicle provided in the embodiments of the present application can reduce the requirements on the ground rail changing device.

Description

technical field [0001] The present application relates to rail vehicle structure technology, in particular to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are generally divided into monorail trains and double-track trains, wherein a double-track train runs along two equidistant tracks. The gauge is the distance between two tracks. Most countries or regions adopt a unified gauge, while some countries or regions have different gauges. Before the rail train drives from a track of one gauge to another gauge of track, it needs to change the track, that is: adjust the distance between the two wheels connected on the same axle in the rail train, so that the wheels The distance between them can be adapted to the new gauge. [0003] By investigating the research on variable gauge bogies in various countries in the world, some countries have different degrees of research, development, testing and even operation of variable gauge bogies. The inventor under...
