Description

Technical Field

[0001] This utility model relates to the field of railway vehicle bogie technology, specifically to a lateral vibration damper structure for railway vehicle bogies. Background Technology

[0002] When rail vehicles are in operation, especially when traveling on curves, the inertia of the rail vehicle can easily cause the vehicle body to tilt, resulting in particularly large vibrations and noises. This not only reduces the comfort of the train ride, but also brings safety hazards to the rail vehicle during operation.

[0003] In the prior art, such as the announcement number CN215621983U, a T-shaped buffer for a railway vehicle bogie is proposed. This technical solution belongs to the technical field of vibration reduction and noise reduction in rail transit, and discloses a T-shaped buffer for a railway vehicle bogie, including a vertical buffer mechanism and a lateral buffer mechanism with a T-shaped structure. One end of the vertical buffer mechanism is connected to the underframe of the car body, and the other end is connected to the center of the lateral buffer mechanism. The two ends of the lateral buffer mechanism are respectively installed laterally on the side beams of the bogie. The vertical buffer mechanism is used to buffer vertical vibrations from the car body, and the lateral buffer mechanism is used to buffer lateral vibrations from between the car body and the bogie. The overall structure of this utility model is simple, easy to use, and has strong applicability.

[0004] However, in the existing technical solution, the transverse bar on the bogie of the rail vehicle needs to be fixed to the bogie with multiple bolts, which makes the disassembly and assembly of the transverse bar inconvenient, thus making it inconvenient for the staff to maintain the rail vehicle bogie.

[0005] To address the aforementioned issues, this application proposes a transverse vibration damper structure for a railway vehicle bogie. Utility Model Content

[0006] This utility model aims to provide a transverse vibration damper structure for a rail vehicle bogie, mainly to solve the problem that the transverse rods on existing rail vehicle bogies need to be fixed to the bogie with multiple bolts, which makes the disassembly and assembly of the transverse rods inconvenient, thus making it inconvenient for workers to maintain the rail vehicle bogie.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A transverse vibration damper structure for a railway vehicle bogie includes a bogie, a transverse rod, and a linear bearing mounted on the transverse rod. Both ends of the transverse rod are slidably connected to mounting blocks. One end of the mounting block has a sliding cavity that matches the transverse rod. The outer wall of the transverse rod is fitted with symmetrical first springs. One end of the first spring is fixedly connected to the linear bearing, and the other end is fixedly connected to the mounting block. The bogie has mounting grooves that match the mounting blocks, and the mounting blocks are provided with limit components.

[0009] The working principle and beneficial effects of this utility model:

[0010] Working principle: When installing the transverse bar on the bogie of this rail vehicle, first insert the mounting block at one end of the transverse bar into one of the mounting slots on the bogie, and then squeeze the mounting block at the other end of the transverse bar. This compresses the two first springs on the transverse bar simultaneously. When the two first springs are compressed to a certain extent, the mounting block can be inserted into the other mounting slot on the bogie. The two mounting blocks will be inserted into the mounting slot under the action of the first springs. At the same time, the mounting blocks can be fixed inside the mounting slot by the limiting components set on the mounting blocks. (When the car body swings left and right, i.e., when lateral vibration occurs, this lateral vibration is transmitted to the hydraulic telescopic bar through the connecting cover connected to the car body, and then to the springs at both ends of the linear bearing. The elastic extension and contraction of the springs effectively consume the lateral vibration and reduce the lateral vibration of the car body.) The part in parentheses is the prior art, which is not described in detail in this application. After releasing the limiting components, the mounting blocks at both ends of the transverse bar are pulled to disengage them from the mounting slots on the bogie, and then the transverse bar can be removed.

[0011] Beneficial effects: After inserting the mounting blocks at both ends of the transverse bar into the mounting slots, the mounting blocks can be fixed inside the mounting slots by the first spring. At the same time, the mounting blocks can be further fixed inside the mounting slots by the limiting component. This makes the device more stable during operation. After releasing the limiting component, the mounting blocks at both ends of the transverse bar can be pulled to disengage them from the mounting slots on the bogie, and the transverse bar can be removed. This makes the disassembly and assembly of the transverse bar more convenient, thereby facilitating the maintenance of the bogie of the rail vehicle by the staff.

[0012] Preferably, the limiting component includes cavities symmetrically arranged inside the mounting block. Each cavity has a sliding plate slidably connected to it. A second spring is fixedly connected to one side of each sliding plate, and the other end of the second spring is fixedly connected to the inner wall of the cavity. A limiting block is fixedly connected to the side of the sliding plate away from the second spring. The side of the limiting block away from the sliding plate extends out of the mounting block, and the limiting block is slidably connected to the mounting block. A limiting groove matching the limiting block is formed on the inner wall of the mounting groove. A button is fixedly connected to the side of the sliding plate opposite the limiting block. The side of the button away from the sliding plate extends out of the mounting block, and the button is slidably connected to the mounting block. Pressing the buttons on the two mounting blocks causes the sliding plate to move into the cavity. Slide the sliding plate while simultaneously compressing the second spring. As the sliding plate slides into the cavity, it simultaneously moves the limiting block. Once the limiting block has moved to a certain extent, the mounting blocks at both ends of the transverse rod can be inserted into the mounting slots on the bogie. After the mounting blocks are fully inserted into the mounting slots, release the button. The sliding plate will then move the limiting block under the action of the second spring and engage with the limiting groove inside the mounting slot, thus fixing the mounting block inside the mounting slot. This makes the device more stable during operation. By pressing the button, the sliding plate moves the limiting block. When the limiting block disengages from the limiting groove, the mounting blocks at both ends of the transverse rod are simultaneously pulled to disengage from the mounting slots on the bogie, allowing the transverse rod to be removed.

[0013] Preferably, symmetrical guide blocks are fixedly connected to both ends of the outer wall of the transverse rod, and guide grooves matching the guide blocks are opened on the inner wall of the sliding cavity. When the mounting block slides at both ends of the transverse rod, the guide blocks at both ends of the transverse rod and the guide grooves opened on the inner wall of the sliding cavity can play a good role in limiting and guiding the mounting block. This not only makes the mounting block more stable when sliding at both ends of the transverse rod, but also effectively prevents the mounting block from detaching from the transverse rod, thereby effectively ensuring the normal operation of the device.

[0014] Preferably, the corner of the limiting block away from the button is set as an inclined surface. By setting the corner of the limiting block away from the button as an inclined surface, when the operator installs the horizontal bar, the inner wall of the installation groove will squeeze the inclined surface of the limiting block to make it move automatically during the process of inserting the mounting block into the installation groove. This eliminates the need for people to press the button to move the limiting block through the sliding plate, thus making the installation of the horizontal bar more convenient.

[0015] Preferably, all corners at the opening of the mounting slot are chamfered. By chamfering all corners at the opening of the mounting slot, it is easier to insert the mounting block into the mounting slot, thus making the installation of the horizontal bar easier.

[0016] Preferably, a rubber pad is fixedly connected to the end of the mounting block away from the transverse bar. By setting the rubber pad at the end of the mounting block away from the transverse bar, not only can the stability of the mounting block be improved when it is inserted into the mounting groove, but also the hard contact between the mounting block and the bogie can be effectively avoided, thereby effectively extending the service life of the bogie.

[0017] Preferably, all corners of the mounting blocks are rounded. By making all corners of the mounting blocks rounded, it is possible to effectively prevent workers from getting their hands scratched by the corners of the mounting blocks when assembling or disassembling the horizontal bars, thus making the assembly and disassembly of the horizontal bars more convenient.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A transverse vibration damper structure for a railway vehicle bogie includes a bogie 1, a transverse rod 2, and a linear bearing 3 mounted on the transverse rod 2. Mounting blocks 4 are slidably connected to both ends of the transverse rod 2. The corners of the mounting blocks 4 are rounded to effectively prevent workers from being scratched by the corners of the mounting blocks 4 when assembling or disassembling the transverse rod 2. One end of the mounting block 4 has a sliding cavity 5 that matches the transverse rod 2. Symmetrical guide blocks 13 are fixedly connected to both ends of the outer wall of the transverse rod 2. The inner wall of the sliding cavity 5 has a guide groove 14 that matches the guide block 13. This not only makes the mounting block 4 more stable when sliding at both ends of the transverse rod 2, but also effectively prevents the mounting block 4 from detaching from the transverse rod 2, thus ensuring the normal operation of the device. Symmetrical first springs 16 are mounted on the outer wall of the transverse rod 2. One end of the first spring 16 is fixedly connected to the linear bearing 3, and the other end is fixedly connected to the mounting block 4. The bogie 1 has mounting grooves 6 that match the mounting blocks 4. When installing the transverse rod 2 on the railway vehicle bogie, firstly... The mounting block 4 at one end of the rod 2 is inserted into one of the mounting slots 6 on the bogie 1. Then, the mounting block 4 at the other end of the transverse rod 2 is squeezed, which simultaneously compresses the two first springs 16 on the transverse rod 2. When the two first springs 16 are compressed to a certain extent, the mounting block 4 can be inserted into the other mounting slot 6 on the bogie 1. The two mounting blocks 4 will be inserted into the mounting slot 6 under the action of the first springs 16. The end of the mounting block 4 away from the transverse rod 2 is fixedly connected with a rubber pad 15. This not only makes the mounting block 4 more stable when inserted into the mounting slot 6, but also effectively avoids hard contact between the mounting block 4 and the bogie 1, thereby effectively extending the service life of the bogie 1. The corners at the opening of the mounting slot 6 are all chamfered, which makes it easier to insert the mounting block 4 into the mounting slot 6, thus making the installation of the transverse rod 2 more convenient. The mounting block 4 is provided with a limit component, which can further fix the mounting block 4 inside the mounting slot 6, thus making the device more stable during operation.

[0025] like Figure 2 and Figure 4As shown, the limiting assembly includes cavities 7 opened inside the mounting block 4, and the cavities 7 are symmetrically arranged inside the mounting block 4. Sliding plates 8 are slidably connected inside each cavity 7. A second spring 9 is fixedly connected to one side of each sliding plate 8, and the other end of the second spring 9 is fixedly connected to the inner wall of the cavity 7. A limiting block 10 is fixedly connected to the side of the sliding plate 8 away from the second spring 9. The side of the limiting block 10 away from the sliding plate 8 extends out of the mounting block 4, and the limiting block 10 is slidably connected to the mounting block 4. A limiting groove 11 matching the limiting block 10 is opened on the inner wall of the mounting groove 6. A button 12 is fixedly connected to one side of the sliding plate 8 located on the limiting block 10. The side of the button 12 away from the sliding plate 8 extends out of the mounting block 4, and the button 12 is slidably connected to the mounting block 4. By pressing the button 12 on the two mounting blocks 4, the sliding plate 8 can be moved towards the cavity 7. The sliding plate 8 slides internally, simultaneously compressing the second spring 9 and placing it in a compressed state. When the sliding plate 8 slides into the cavity 7, it can simultaneously drive the limiting block 10 to move. After the limiting block 10 moves to a certain extent, the mounting blocks 4 at both ends of the transverse rod 2 can be inserted into the mounting slots 6 on the bogie 1. After the mounting blocks 4 are fully inserted into the mounting slots 6, the button 12 is released. The sliding plate 8 will drive the limiting block 10 to move under the action of the second spring 9 and engage with the limiting groove 11 inside the mounting slot 6, thus fixing the mounting blocks 4 inside the mounting slot 6. This makes the device more stable during operation. By pressing the button 12, the sliding plate 8 drives the limiting block 10 to move. When the limiting block 10 disengages from the limiting groove 11, the mounting blocks 4 at both ends of the transverse rod 2 are pulled to disengage from the mounting slots 6 on the bogie 1, thus removing the transverse rod 2.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When installing the transverse bar 2 on the bogie of this rail vehicle, first insert the mounting block 4 at one end of the transverse bar 2 into one of the mounting slots 6 on the bogie 1. During the insertion of the mounting block 4 into the mounting slot 6, the inner wall of the mounting slot 6 will press against the inclined surface of the limiting block 10, causing it to move. At the same time, the sliding plate 8 slides into the cavity 7, which will compress the second spring 9. After the mounting block 4 is fully inserted into the mounting slot 6, the sliding plate 8 will drive the limiting block 10 to move under the action of the second spring 9 and engage with the limiting groove 11 inside the mounting slot 6, thus fixing the mounting block 4 inside the mounting slot 6. Then, press the mounting block 4 at the other end of the transverse bar 2, which will simultaneously compress the two first springs 16 on the transverse bar 2. When the two first springs 16 are compressed to a certain extent, the mounting block 4 can be inserted into the other mounting slot 6 on the bogie 1. Inside the mounting slot 6, once the limiting block 10 on the mounting block 4 engages with the limiting slot 11, the installation of the transverse rod 2 can be completed. (When the car body swings left and right, i.e., transverse vibration occurs, this transverse vibration is transmitted to the hydraulic telescopic rod through the connecting cover connected to the car body, and then to the springs at both ends of the linear bearing. The elastic extension and contraction of the springs effectively consumes the transverse vibration and reduces the transverse vibration of the car body.) The part in parentheses is prior art, which is not described in detail in this application. By pressing the button 12, the limiting block 10 is moved through the sliding plate 8. When the limiting block 10 disengages from the limiting slot 11, the mounting blocks 4 at both ends of the transverse rod 2 are pulled to disengage from the mounting slot 6 on the bogie 1, and the transverse rod 2 can be disassembled. This makes the disassembly and assembly of the transverse rod 2 more convenient, thereby facilitating the maintenance of the bogie of the rail vehicle by the staff.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
