Description

Technical Field

[0001] This utility model belongs to the technical field of brake pad heat dissipation and noise reduction structure, specifically a modular heat dissipation and noise reduction structure for train brake pads that can be quickly replaced. Background Technology

[0002] The train brake pad module is a key component of the train braking system, used to slow down or stop a moving train. Its working principle is to generate friction through contact with the wheels or brake discs, converting the train's kinetic energy into heat energy and dissipating it into the atmosphere, thereby achieving the purpose of braking.

[0003] In existing technology, train brake pads typically have a heat dissipation and noise reduction structure on their inner side. This structure effectively dissipates heat and reduces noise by using heat dissipation fins and sound-absorbing cotton. However, when the heat dissipation and noise reduction structure is used in conjunction with the train brake pads, the brake pads on the inner side are usually connected to the structure via bolts with multiple holes. Therefore, when the structure needs to be replaced, it is necessary to loosen the connecting bolts one by one using auxiliary tools. This process is relatively complicated and time-consuming, so improvements are needed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a modular heat dissipation and noise reduction structure for train brake pads that can be quickly replaced.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular heat dissipation and noise reduction structure for train brake pads that can be quickly replaced, comprising a heat dissipation and noise reduction structure, a brake structure being provided inside the heat dissipation and noise reduction structure, and a snap-fit ​​component being provided inside the heat dissipation and noise reduction structure, the snap-fit ​​component extending into the interior of the brake structure;

[0006] The heat dissipation and noise reduction structure includes a mounting frame, the inner cavity of which is provided with sound-absorbing cotton, and a limit ring is provided inside the sound-absorbing cotton;

[0007] The brake structure includes a brake pad, a connecting rod is provided on the outer side of the brake pad, the inner side of the connecting rod passes through the limiting ring and extends into the inner cavity of the mounting bracket, and an inclined groove is provided inside the connecting rod;

A bolt is provided on the outer side of the mounting bracket, and a pressure block located in the inner cavity of the mounting bracket is threaded onto the outer surface of the bolt. The outer wall of the pressure block is movably connected to the outer surface of the connecting post, and the snap-fit ​​block is elastically connected to the mounting bracket through a spring piece.

[0009] Preferably, the mounting bracket is provided on both sides, and the bracket has a mounting groove inside.

[0010] Preferably, the mounting bracket is provided with heat dissipation fins on its outer side, and the heat dissipation fins are wavy in shape.

[0011] Preferably, the outer side of the card block is provided with an inclined surface, which is adapted to the inner wall of the inclined groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model is equipped with a pressure block and a locking block.

[0022] 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.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, this is the first embodiment of the utility model, which provides a modular heat dissipation and noise reduction structure for train brake pads that can be quickly replaced. It includes a heat dissipation and noise reduction structure 1, a brake structure 2 disposed inside the heat dissipation and noise reduction structure 1, and a snap-fit ​​component 3 disposed inside the heat dissipation and noise reduction structure 1, which extends into the brake structure 2.

[0025] Among them, the heat dissipation and noise reduction structure 1 includes a mounting bracket 101, and the inner cavity of the mounting bracket 101 is provided with sound-absorbing cotton 105, and the sound-absorbing cotton 105 is provided with a limit ring 104 inside;

[0026] Brake structure 2 includes brake pad 201. A connecting rod 202 is provided on the outer side of brake pad 201. The inner side of the connecting rod 202 passes through the limiting ring 104 and extends into the inner cavity of the mounting bracket 101. An inclined groove 203 is provided inside the connecting rod 202.

[0027] The snap-fit ​​assembly 3 includes a mounting ring 301. The outer side of the mounting ring 301 is connected to the inner wall of the mounting bracket 101. The inner wall of the mounting ring 301 is movably connected to the outer surface of the connecting rod 202. A snap-fit ​​block 303 is provided on the inner wall of the mounting bracket 101. The outer side of the snap-fit ​​block 303 extends into the inner cavity of the inclined groove 203. A connecting post 304 is provided at the other end of the snap-fit ​​block 303. A bolt 307 is provided on the outer side of the mounting bracket 101. A pressure block 306 located in the inner cavity of the mounting bracket 101 is threaded onto the outer surface of the bolt 307. The outer wall of the pressure block 306 is movably connected to the outer surface of the connecting post 304. The snap-fit ​​block 303 is elastically connected to the mounting bracket 101 through a spring piece 302.

[0028] When the operator rotates the bolt 307, the pressure block 306 moves within the mounting bracket 101, releasing the pressure on the connecting post 304. Since the spring plate 302 is under pressure, it applies upward pressure to the locking block 303, causing the entire locking block 303 to move upwards, bringing the connecting post 304 into close contact with the pressure block 306. Simultaneously, the other end of the locking block 303 moves out of the inclined groove 203, releasing its engagement with the connecting rod 202. This allows the operator to easily remove the connecting rod 202 from the mounting bracket 101 and the inner cavity of the limiting ring 104, releasing its overall fixation to the brake pad 201 and the sound-absorbing cotton 105. This facilitates quick replacement by the operator, eliminating the need to rotate multiple bolts sequentially for connection, thus providing greater convenience.

[0029] Example 2

[0030] like Figure 2 and Figure 4 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that brackets 102 are provided on both sides of the mounting bracket 101, and mounting grooves are provided inside the brackets 102.

[0031] The assembled train wheel module is mounted on the outside of the wheel hub through the mounting slot on the bracket 102, and brakes are applied to it through the brake pads 201.

[0032] Among them, heat dissipation fins 103 are provided on the outer side of the mounting bracket 101, and the heat dissipation fins 103 are wavy in shape;

[0033] When the brake pads 201 are in use, the heat generated by braking is absorbed by the connecting rod 202 and directed to the outside of the heat dissipation fins 103. At the same time, when the vehicle is moving, the external airflow blows onto the outside of the heat dissipation fins 103. The wave-shaped heat dissipation fins 103 guide the airflow, increasing the area of ​​the airflow passing through the heat dissipation fins 103 and thus increasing the amount of heat it carries, which greatly improves the heat dissipation effect on the connecting rod 202.

[0034] Among them, the outer side of the card block 303 is provided with an inclined surface, which is adapted to the inner wall of the inclined groove 203;

[0035] The bolt 307 drives the pressure block 306 to press down continuously, squeezing and moving the connecting column 304 downward, thereby driving the locking block 303 to be inserted into the inclined groove 203. Through the inclined surface squeezing, the connecting rod 202 is moved inward, so that the brake pad 201 is tightly attached to the outside of the mounting bracket 101 to prevent unstable installation.

[0036] Among them, the inner wall of the mounting bracket 101 is provided with a limit block, and the inner side of the limit block is movably connected to the outer surface of the locking block 303;

[0037] When the card block 303 moves, the card block 303 is limited by the limit block to prevent it from shifting its position and thus prevent the fixed position from shifting.

[0038] Among them, the inner wall of the mounting bracket 101 is provided with a limiting rod 305, and the outer surface of the limiting rod 305 is connected to the inner wall of the mounting bracket 101;

[0039] When the operator rotates the bolt 307, the bolt 307 drives the pressure block 306 to move on the outer surface of the limit rod 305, thereby limiting the pressure block 306 through the limit rod 305 to prevent it from shifting position.

[0040] Working principle and usage process of this utility model:

[0041] First, when the operator replaces a damaged component of the modular heat dissipation and noise reduction structure for train brake pads, rotating the bolt 307 causes the pressure block 306 to move upward on the outer surface of the limit rod 305, moving the pressure block 306 away from the top of the connecting post 304 and relieving it from pressing against the connecting post 304. Simultaneously, due to the elastic force of the spring piece 302, the locking block 303 moves obliquely upward, causing the connecting post 304 and the pressure block 306 to fit tightly together. As the locking block 303 moves obliquely upward, its other end moves out of the inclined groove 203. This releases the pressure on the connecting rod 202 and removes its fixation, allowing the operator to easily remove the connecting rod 202 from the mounting bracket 101. This facilitates the disassembly of the brake pad 201 and also releases the restriction on the sound-absorbing cotton 105 and the limiting ring 104, making it easier to remove the sound-absorbing cotton 105 entirely from the inner cavity of the mounting bracket 101 for replacement. This allows the operator to easily replace different parts without having to replace the entire device, reducing operating costs and improving installation efficiency.
