Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle bogies, specifically to a quick-adjustment mounting bracket for a bogie anti-hunting shock absorber. Background Technology

[0002] During railway vehicle operation, the snaking motion of the bogie is an important factor affecting the stability and safety of vehicle operation. As a key component for suppressing this motion, the installation accuracy and stability of the anti-snaking damper are directly related to the damping effect.

[0003] Currently, the installation of anti-hunting shock absorber mounting brackets often suffers from problems such as inconvenient adjustment, low installation efficiency, and insufficient stability in connection with the bogie. Traditional mounting brackets mostly employ fixed structures, making rapid adjustments impossible based on actual installation conditions. This leads to difficulties in accurately positioning the anti-hunting shock absorber during installation and makes it prone to loosening due to vibrations during vehicle operation, affecting damping performance and increasing maintenance costs and safety hazards. Therefore, those skilled in the art have provided a quick-adjustment mounting bracket for bogie anti-hunting shock absorbers to address these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a quick-adjustment mounting bracket for a bogie anti-hunting shock absorber.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] The quick-adjustable mounting bracket for the bogie anti-hunting damper includes:

[0007] The two supports are set in parallel.

[0008] A mounting plate is located between the two brackets;

[0009] Multiple threaded posts are symmetrically arranged on both sides of the mounting plate, and the threaded posts pass through two of the brackets respectively;

[0010] Multiple guide grooves are symmetrically distributed within the mounting plate, with one end perpendicular to the bracket and the other end parallel to the bracket, and the middle part is arc-shaped.

[0011] Multiple sliders are slidably disposed at the openings of the multiple guide grooves, and can slide along their own central axis.

[0012] Multiple balls are located within the guide groove;

[0013] Multiple springs are located between the balls and can extend and retract along the arc-shaped portion of the guide groove;

[0014] When the slider abuts against the bracket, the mounting plate is positioned between the two brackets. During the process of fixing the anti-hunting damper to the mounting plate, the other slider is squeezed, which compresses the spring and increases the contact force with the bracket.

[0015] Preferably, the mounting plate is provided with mounting holes for the anti-hunting damper, and a plurality of sliders parallel to the bracket are located between the mounting holes.

[0016] Preferably, the outer diameter of the spring, the diameter of the ball, and the diameter of the guide groove are equal, and are equal to the diameter of the portion of the slider located in the guide groove.

[0017] Preferably, the bracket is configured as an "L" shape, and the bend of the bracket is provided with reinforcing ribs.

[0018] Preferably, a nut is threaded onto the threaded post, and the nut is located on the outside of the bracket.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] 1. After the slider and the bracket abut against each other, the mounting plate is positioned in the middle of the two brackets. During the process of fixing the anti-hunting damper to the mounting plate, the other slider is squeezed, which compresses the spring and increases the contact force with the bracket, making the installation more stable. Since the nut is located on the outside of the bracket, the gap between the bracket and the mounting plate can be supported, ensuring the stability of the inner and outer sides of the bracket.

[0021] 2. By rotating the nut, the position of the mounting plate can also be adjusted, causing the mounting plate to tilt towards one side of the bracket. When the position of the hole on the side beam of the vehicle body for connecting the bracket is inaccurate, or when the drilling position is within a certain range, it can be adjusted adaptively. The operation is simple and quick, and can ensure the alignment of the anti-hunting shock absorber and the bogie. Attached Figure Description

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Quick-adjustable mounting bracket for bogie anti-hunting shock absorber, refer to Figure 1-3 ,include:

[0029] Two supports 1 are set in parallel. The supports 1 are set in an "L" shape, and the bends of the supports 1 are reinforced with ribs to enhance the structural strength of the supports 1. The two supports 1 are installed on the side beam of the chassis of the vehicle body.

[0030] Mounting plate 2 is located between two brackets 1. Mounting plate 2 is provided with mounting holes for anti-hunting vibration dampers, which facilitates the installation and fixing of anti-hunting vibration dampers.

[0031] Multiple threaded posts 21 are symmetrically arranged on both sides of the mounting plate 2, and the threaded posts 21 pass through the two brackets 1 respectively. Nuts are installed on the threaded posts 21 by threads. The nuts are located on the outside of the brackets 1. By tightening the nuts, the relative positions of the mounting plate 2 and the brackets 1 can be initially fixed.

[0032] Multiple guide grooves 3 are symmetrically distributed within the mounting plate 2, with one end perpendicular to the bracket 1 and the other end parallel to the bracket 1, and the middle part is arc-shaped.

[0033] Multiple sliders 31 are slidably disposed at the openings of multiple guide grooves 3, and can slide along their own central axis. The multiple sliders 31 parallel to the bracket 1 are located between the mounting holes for the anti-hunting vibration damper.

[0034] Multiple balls 32 are located in the guide groove 3 for force transmission and to facilitate changing the direction of force.

[0035] Multiple springs 33 are located between the balls 32 and can extend and retract along the arc of the guide groove 3. The compressed springs 33 provide strong cushioning force and can also adapt to the gap between the two supports 1, resulting in good performance. The outer diameter of the springs 33, the diameter of the balls 32, and the diameter of the guide groove 3 are equal, and the diameter of the portion of the slider 31 located in the guide groove 3 is also equal. This design ensures that the slider 31, balls 32, and springs 33 can move smoothly within the guide groove 3.

[0036] After the slider 31 abuts against the bracket 1, the mounting plate 2 is positioned in the middle of the two brackets 1. During the process of fixing the anti-hunting damper to the mounting plate 2, the other slider 31 is squeezed, which compresses the spring 33 and increases the contact force with the bracket 1, making the installation more stable. Since the nut is located on the outside of the bracket 1, the gap between the bracket 1 and the mounting plate 2 can be supported, ensuring the stability of the inner and outer sides of the bracket 1.

[0037] By rotating the nut, the position of the mounting plate 2 can be adjusted so that the mounting plate 2 is tilted toward the bracket 1 on one side. When the position of the hole on the side beam of the chassis for connecting the bracket 1 is inaccurate, or when the position of the hole is within a certain range, it can be adjusted adaptively. The operation is simple and quick, and can ensure the alignment of the anti-hunting shock absorber and the bogie.

[0038] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
