Description

Technical Field

[0001] This utility model relates to the field of bogie technology, and in particular to a swing device for a swing bogie. Background Technology

[0002] The oscillation mechanism of a swaying bogie is a key technology in modern railway vehicles, mainly used to improve the vehicle's operational stability and efficiency.

[0003] However, the following drawbacks still exist. Traditional bogie designs mainly rely on fixed wheelbase and bogie structure, which to some extent limits the performance of vehicles under complex terrain and high-speed operating conditions. In contrast, the swing bogie introduces a swing mechanism, which allows the wheels to swing flexibly relative to the bogie, thereby effectively reducing the impact force between the wheel and rail, improving the vehicle's running stability, reducing wheel and rail wear, extending service life, and improving operating efficiency. In order to better address the above problems, promote the development of industry technology, and enhance core competitiveness, this application proposes a new composition structure that is different from the existing technology. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a swing device for a swing bogie.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A swing device for a swing bogie includes an H-frame. A docking plate for connecting a train is fixedly connected at the center of the H-frame. Two air springs are fixedly connected to the top of the H-frame. Wheelsets are rotatably connected to both ends of the H-frame via bearings. Two limiting blocks are fixedly connected to the outer side of the wheelsets. Two L-shaped plates are fixedly connected to the H-frame, and the wheelsets pass through the L-shaped plates. Two fixing blocks are fixedly connected to the top of the L-shaped plates. A rotating plate is fixedly connected to one side of each of the two fixing blocks. A connecting plate fixed to the H-frame is fixedly connected to the top of the multiple limiting blocks, and the rotating plate is fixed to the connecting plate.

[0007] As a further embodiment of this utility model, the H-shaped frame is fixedly connected to a limiting frame and a connecting frame at multiple ends, and a vertical shock absorber is fixedly connected between the upper and lower opposing limiting frames and connecting frames.

[0008] As a further embodiment of this utility model, counterweights are fixedly connected to both sides of the H-shaped frame, and the two counterweights are symmetrically distributed.

[0009] As a further improvement of this utility model, limit rings are fixedly connected to both ends of the counterweight.

[0010] As a further improvement of this utility model, a first anti-snake-like shock absorber is fixedly connected to both sides of the docking plate inside the H-shaped frame.

[0011] As a further embodiment of this utility model, the H-shaped frame is fixedly connected to a fixing frame at both ends of the counterweight on both sides.

[0012] As a further improvement of this utility model, a U-shaped frame is fixedly connected to one side of the fixed frame, and a second anti-snake-like shock absorber is fixedly connected inside the U-shaped frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using H-frames and wheelsets in combination, when a train is running on curved tracks, the H-frames and wheelsets can cause the carriages to sway, thereby effectively reducing the impact force between the wheels and rails, improving the smoothness of vehicle operation, reducing wheel and rail wear, extending service life, and improving operating efficiency.

[0015] 2. Through the combined use of the first and second anti-hunting shock absorbers, the first and second anti-hunting shock absorbers are used to suppress the lateral vibration and swaying of the carriage in the horizontal plane, especially to prevent dangerous "hunting motion" and ensure smooth operation and safety.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0021] Reference Figures 1-3 A swing device for a swing bogie includes an H-frame 10, a docking plate 11 for connecting a train is fixed to the center of the H-frame 10 by bolts, and two air springs 1 are fixed to the top of the H-frame 10 by bolts, the model of which can be selected as appropriate, such as one of Kurashiki PSB-1-500Y or Matsumoto GF40 / 60-1;

[0022] Inside the H-frame 10, wheelsets 12 are rotatably connected at both ends via bearings. The H-frame 10 is installed at the bottom of the carriage via the docking plate 11, allowing the carriage to move via the wheelsets 12 on the H-frame 10.

[0023] When the car travels on a curved track, the H-frame 10 and wheelset 12 cause the car to sway. When the bogie deviates, the lateral stiffness characteristics of the air spring 1 generate an automatic restoring torque. The restoring force accumulated by the spring deformation pulls the car body back to the center position, thus keeping the sway amplitude of the H-frame 10 and wheelset 12 within 3.0°. This prevents the wheelset 12 from detaching from the track, effectively reducing the impact force between the wheel and rail, improving the smoothness of vehicle operation, reducing wheel and rail wear, extending service life, and improving operating efficiency.

[0024] In this utility model, two limiting blocks 3 are welded to the outer side of the wheelset 12, and a connecting plate 2 fixed to the H-shaped frame 10 is welded to the top of the multiple limiting blocks 3. Two L-shaped plates 4 are fixed inside the H-shaped frame 10 by bolts, and the wheelset 12 passes through the L-shaped plates 4. Two fixing blocks 6 are welded to the top of the L-shaped plates 4, and a rotating plate 5 is welded to one side of each of the two fixing blocks 6, and the rotating plate 5 is fixed to the connecting plate 2.

[0025] Limiting block 3 limits the movement of wheelset 12. When the bogie rotates close to 3.0°, mechanical interference forces further deviation to avoid running beyond the angle, thus ensuring the stability of wheelset 12's movement. At the same time, connecting plate 2 is fixed to limiting block 3, further ensuring the stability of wheelset 12.

[0026] In particular, limit frames 15 and connecting frames 13 are welded to multiple ends of the H-frame 10. Vertical shock absorbers 14 are fixed between the upper and lower opposing limit frames 15 and connecting frames 13 by bolts. The vertical shock absorbers 14 can reduce the vertical sway of the carriage and further ensure the safety of the carriage.

[0027] The H-frame 10 has counterweights 8 fixed to both sides by bolts, and the two counterweights 8 are symmetrically distributed. Limiting rings 7 are welded to both ends of the counterweights 8. The counterweights 8 can increase the vertical weight of the H-frame 10, further improving the safety of the H-frame 10.

[0028] In particular, the first anti-snake shock absorber 16 is fixed to both sides of the docking plate 11 inside the H-shaped frame 10 by bolts. The fixing frame 9 is fixed to both sides of the counterweight block 8 by bolts. The U-shaped frame 18 is fixed to one side of the fixing frame 9 by bolts. The second anti-snake shock absorber 17 is fixed to the U-shaped frame 18 by bolts. The model of the two shock absorbers can be selected as 04R-1722.

[0029] During the swaying of the carriage, the first anti-sway damper 16 and the second anti-sway damper 17 are used to suppress the lateral vibration and swaying of the carriage in the horizontal plane, especially to prevent dangerous "swaying motion" and ensure smooth operation and safety.

[0030] Working principle: When needed, the H-frame 10 is installed at the bottom of the carriage via the docking plate 11, allowing the carriage to move via the wheelsets 12 on the H-frame 10. When the carriage travels on the curved track, the carriage swings via the H-frame 10 and wheelsets 12, and the swing amplitude of the H-frame 10 and wheelsets 12 is within 3.0°, thus preventing the wheelsets 12 from detaching from the track.

[0031] During the swaying of the carriage, the first anti-sway shock absorber 16 and the second anti-sway shock absorber 17 are used to suppress the lateral vibration and swaying of the carriage in the horizontal plane, especially to prevent dangerous "swaying motion" and ensure smooth operation and safety. Thus, the vertical shock absorber 14 can reduce the vertical sway of the carriage and further ensure the safety of the carriage. At the same time, the counterweight 8 can increase the vertical weight of the H-frame 10 and further improve the safety of the H-frame 10.
