Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically a brake pad. Background Technology

[0002] Brake pads decelerate or stop trains by generating friction with the brake disc. During the braking process of high-speed trains, a strong frictional force is generated between the brake pads and the brake disc, forming a braking force that prevents the train wheels from rotating. Therefore, the performance of the brake pads directly affects the braking performance of the train. The brake pads used in trains are generally fixed with rivets. This brake pad structure is not convenient when installing the connection between the friction pads and the steel backing. At the same time, the disassembly process is relatively cumbersome and inefficient when replacing or maintaining the friction pads. Summary of the Invention

[0025] 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.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a brake pad, comprising: a steel backing 1; mounting through holes 2 equidistantly opened inside the steel backing 1; mounting posts 4 installed inside the mounting through holes 2; friction pads 7 fixedly connected to one end of the mounting posts 4; a bottom fixing box 9 fixedly connected to the end of the mounting posts 4 away from the friction pads 7; a limiting mounting assembly placed inside the bottom fixing box 9, the limiting mounting assembly including inclined plate blocks 10, the inclined plate blocks 10 being equidistantly slidably arranged inside the bottom fixing box 9; and inner grooves 20 equidistantly opened inside the mounting through holes 2, the inner grooves 20 cooperating with the inclined plate blocks 10.

[0027] It is understood that, in this invention, when installing the friction plate 7, the mounting post 4 is aligned with the mounting through hole 2, a butterfly spring 8 is fitted on the outside of the mounting post 4, the limiting side plate 5 on the outside of the mounting post 4 is aligned with each limiting inner groove 6 on the inside of the mounting through hole 2, the mounting post 4 is inserted into the mounting through hole 2, and the mounting post 4 is pressed down. The mounting post 4 drives the bottom fixing box 9 into the mounting through hole 2. When the bottom fixing box 9 enters, the connecting groove 3 at the top of the mounting through hole 2 will push against the bottom slope of the inclined plate block 10. The inclined plate block 10 drives the fixed slide frame 11 to move into the bottom fixing box 9. When the fixed slide frame 11 moves, it passes through the limiting groove 1. 4. The adjusting rod 13 moves, which in turn moves the fixed top plate 12 and the adjusting slide plate 15, pressing the return spring 16. When the inclined block 10 reaches the position of the inner slot 20, the return spring 16 resets and moves the adjusting slide plate 15 and the fixed top plate 12 back to their original positions. The fixed top plate 12 then moves the adjusting rod 13 back to its original position. The adjusting rod 13 pushes the limiting slide groove 14, which in turn moves the fixed slide frame 11 and the inclined block 10 back to their original positions. The inclined block 10 moves outward into the inner slot 20, which restricts its position. Then, the inner threaded limiting cap 19 is threaded onto the bottom of the outer threaded cylinder 18. The internal thread limiting cap 19 tightens and limits the position of the pull rod 17, the adjusting slide plate 15, and the fixed top plate 12, and stabilizes the bottom fixing box 9 and the mounting column 4 inside the mounting through hole 2. The disc spring 8 pushes the friction plate 7 inside the connecting groove 3. The inclined block 10 is limited by the internal slot 20 to facilitate buffering when the friction plate 7 is under force. The train decelerates through friction between each friction plate 7 and the brake disc. When it is necessary to disassemble the friction plate 7 as a whole, the internal thread limiting cap 19 on the outside of the external threaded cylinder 18 is removed by rotating it, and the pull rod 17 is pulled down. The adjusting slide plate 15 and the fixed top plate 12 move downwards, the adjusting slide plate 15 presses the return spring 16, the fixed top plate 12 drives the adjusting rod 13 to move, the adjusting rod 13 drives the fixed slide frame 11 and the inclined block 10 to move inwards through the limiting slide groove 14, completing the disengagement between the inclined block 10 and the inner groove 20. At this time, the friction plate 7 can be pulled upwards, and the butterfly spring 8 is also forced to push the friction plate 7 upwards. When the mounting column 4 drives the bottom fixing box 9 and the inclined block 10 to the position above the inner groove 20, the friction plate 7, the mounting column 4, and the bottom fixing box 9 can be taken out from the mounting through hole 2 for overall replacement, which improves efficiency.

[0028] Please see Figure 1 and Figure 6The bottom fixed box 9 has multiple fixed sliding frames 11 equidistantly slidably arranged inside. The outer side of the fixed sliding frame 11 is fixedly connected to the inclined block 10. The inner side of the fixed sliding frame 11 is movably connected to the fixed top plate 12. The fixed top plate 12 is slidably connected to the bottom fixed box 9. The outer side of the fixed top plate 12 is symmetrically fixedly connected to the adjusting rod 13. The fixed sliding frame 11 has a limit sliding groove 14 inside. The adjusting rod 13 is slidably connected to the limit sliding groove 14.

[0029] It is understood that the present invention can drive the adjusting rod 13 to move synchronously by moving the fixed top plate 12. When the adjusting rod 13 moves, it pushes the fixed slide frame 11 through the limiting slide groove 14 to move, thereby completing the position adjustment of the inclined block 10.

[0030] Please see Figure 1 and Figure 6 An adjustable slide plate 15 is slidably installed inside the bottom fixing box 9. The bottom of the fixed top plate 12 is fixedly connected to the adjustable slide plate 15. Multiple return springs 16 are equidistantly arranged at the bottom of the adjustable slide plate 15. One end of the return spring 16 is fixedly connected to the bottom fixing box 9. A pull rod 17 is fixedly connected to the bottom of the adjustable slide plate 15. The pull rod 17 is slidably connected to the bottom fixing box 9.

[0031] It is understood that this utility model uses a reset spring 16 to reset the sliding adjustment slide 15 inside the bottom fixing box 9.

[0032] Please see Figure 1 and Figure 6 It also includes a connecting groove 3, which is opened at the top of the mounting through hole 2, and a butterfly spring 8 is provided on the outside of the mounting post 4.

[0033] It is understood that this utility model uses a butterfly spring 8 to push the friction plate 7, mounting post 4 and bottom fixing box 9 upward, so that each friction plate 7 is in full contact with the brake disc.

[0034] Please see Figure 1 and Figure 6 The bottom of the bottom fixing box 9 is fixedly connected to an external threaded cylinder 18, which is located outside the pull rod 17. An internal threaded limiting cap 19 is installed below the external threaded cylinder 18 and cooperates with the pull rod 17.

[0035] It is understood that the internal thread limiting cap 19 of this utility model is installed on the outer thread of the external thread cylinder 18. The internal thread limiting cap 19 limits the position of the pull rod 17 inside the external thread cylinder 18, thereby ensuring that the positions of the pull rod 17, the adjusting slide plate 15 and the fixed top plate 12 are fixed.

[0036] Please see Figure 1 and Figure 6Multiple limiting side plates 5 are fixed at equal intervals on the outer side of the mounting column 4, and multiple limiting inner grooves 6 that cooperate with the limiting side plates 5 are symmetrically opened on the inner side of the mounting through hole 2.

[0037] It is understood that this utility model uses the limiting side plate 5 on the outside of the mounting column 4 and the limiting inner groove 6 on the inside of the mounting through hole 2 to limit and fix the device, which facilitates the limiting installation.
