Description

Technical Field

[0001] This utility model relates to the field of automotive brake pad technology, and in particular to an automotive brake pad that is resistant to high temperatures and has high heat dissipation. Background Technology

[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction pads bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Friction generates a lot of heat, so automotive brake pads need to be cooled to ensure their normal use.

[0003] Most existing automotive brake pads rely solely on the material itself for heat dissipation, which is insufficient. They cannot quickly reduce the temperature of overheated brake pads, causing them to soften and wear more severely over time, which is detrimental to the device's performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature resistant and high-heat-dissipation automotive brake pad.

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

[0006] A high-temperature resistant and high-heat-dissipation automotive brake pad includes: a mounting base on which a brake pad is fixedly mounted, the brake pad having multiple heat dissipation holes; a fixing ring rotatably connected to the mounting base; a connecting pipe rotatably connected to the fixing ring; and a water tank fixedly connected to the connecting pipe; and a striking structure including a connecting block slidably mounted on the mounting base, a mounting block fixedly connected to the side wall of the connecting block, a fixing block fixedly connected to the side wall of the mounting block, and a striking plate fixedly mounted on the fixing block. The striking plate is slidably connected to the mounting base, and the striking plate has a specific shape. Corresponding to the brake pads, a transmission structure is installed on the mounting base. The transmission structure includes an impact impeller fixedly connected to the inner wall of a fixed ring. A fixed shaft is rotatably connected to the top of the mounting base. The fixed ring and the fixed shaft are connected by a belt drive assembly. A fixed cam is fixedly connected to the fixed shaft. The position of the fixed cam corresponds to that of the connecting block. A sliding block is fixedly connected to the bottom of the connecting block. A sliding groove matching the sliding block is opened on the mounting base. A fixed spring is fixedly connected to the side wall of the sliding block. The fixed spring is fixedly connected to the inner wall of the sliding groove.

[0007] Preferably, both the fixed cam and the connecting block are fixedly wrapped with a protective layer on their outer sides, and the sidewalls of the connecting block have rounded corners.

[0008] Preferably, a rotating fan blade is fixedly sleeved on the outer side of the fixing ring, and the rotating fan blade is installed facing the brake pad.

[0009] Preferably, the mounting base has a cooling cavity inside, the cooling cavity is in contact with the brake pad, and the connection between the fixing ring and the mounting base and the connecting pipe is fixedly fitted with a sealing gasket.

[0010] Preferably, a control valve is installed inside the connecting pipe, and the control valve is controlled by the vehicle system.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By combining a striking structure with heat dissipation holes, the brake pads are slightly deformed when struck, causing the heat dissipation holes to contract and expand, essentially "breathing," thus expelling heat. At the same time, the circulation of water further dissipates heat, allowing the brake pad temperature to drop quickly and extending the lifespan of the brake pads. Attached Figure Description

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Reference Figures 1-3A high-temperature resistant and high-heat-dissipation automotive brake pad includes: a mounting base 1, on which a brake pad 2 is fixedly mounted, the brake pad 2 having multiple heat dissipation holes; a fixing ring 3 rotatably connected to the mounting base 1; a connecting pipe 4 rotatably connected to the fixing ring 3; and a water tank, which is the vehicle's own water tank, fixedly connected to the connecting pipe 4; and a striking structure, including a connecting block 8 slidably mounted on the mounting base 1; a mounting block 10 fixedly connected to the side wall of the connecting block 8; a fixing block 7 fixedly connected to the side wall of the mounting block 10; and a striking plate 6 fixedly mounted on the fixing block 7. The striking plate 6 is slidably connected to the mounting base 1, and the shape of the striking plate 6 corresponds to the brake pad 2. The brake pad 2 has a certain elasticity and can undergo elastic deformation. A transmission structure is installed on the mounting base 1. Under the action of the transmission structure, the connecting block 8 moves back and forth, driving the mounting block 10 and the fixing block 7 to move back and forth together, so that the striking plate 6, which is fixedly connected to the fixing block 7, moves accordingly. During the movement of the striking plate 6, it will strike the brake pad 2, causing the brake pad 2 to undergo slight deformation, so that the heat dissipation holes will continuously contract and expand, forming a breathing state for heat dissipation; the transmission structure The structure includes an impact impeller 16 fixedly connected to the inner wall of a fixed ring 3, a fixed shaft 14 rotatably connected to the top of a mounting base 1, a belt drive assembly 9 connecting the fixed ring 3 and the fixed shaft 14, a fixed cam 11 fixedly connected to the fixed shaft 14, the position of the fixed cam 11 corresponding to the connecting block 8, a sliding block 15 fixedly connected to the bottom of the connecting block 8, a sliding groove 12 matching the sliding block 15 on the mounting base 1, a fixed spring 13 fixedly connected to the side wall of the sliding block 12, and the fixed spring 13 fixedly connected to the inner wall of the sliding groove 12; water When the flow passes through the fixed ring 3, it impacts the impeller 16, causing the impeller 16 to rotate and drive the fixed ring 3 to rotate as well. Under the action of the belt drive assembly 9, the fixed shaft 14 rotates with the fixed ring 3. When the fixed shaft 14 rotates, it rotates together with the fixed cam 11 that is fixedly connected to it. When the fixed cam 11 rotates, it squeezes the connecting block 8, causing the connecting block 8 to move and deform the fixed spring 13. After the fixed cam 11 rotates to the point where it separates from the connecting block 8, the fixed spring 13 returns to its original shape and pushes the connecting block 8 to move back and forth.

[0019] The outer sides of the fixed cam 11 and the connecting block 8 are both covered with a protective layer. The side wall of the connecting block 8 has rounded corners to protect the fixed cam 11 and the connecting block 8. A rotating fan blade 5 is fixedly sleeved on the outer side of the fixed ring 3. The rotating fan blade 5 is installed facing the brake pad 2. When the fixed ring 3 rotates, the rotating fan blade 5 fixedly sleeved on the fixed ring 3 rotates accordingly, generating airflow to further cool the brake pad 2.

[0020] The mounting base 1 has a cooling chamber inside, which is in contact with the brake pad 2. The connection between the retaining ring 3 and the mounting base 1 and the connecting pipe 4 is fixedly equipped with a sealing gasket to seal the connecting pipe 4 and prevent coolant leakage. The connecting pipe 4 has a control valve installed inside, which is controlled by the vehicle system. The vehicle system automatically adjusts the control valve to regulate the opening degree of the control valve, thereby regulating the flow rate of coolant.

[0021] In this invention, during heat dissipation, water flows through the connecting pipe 4 and the mounting base 1 to dissipate heat from the brake pads 2. As the water flows through the fixed ring 3, it impacts the impeller 16, causing it to rotate and thus rotating the fixed ring 3. Under the action of the belt drive assembly 9, the fixed shaft 14 rotates with the fixed ring 3. When the fixed shaft 14 rotates, the fixed cam 11, which is fixedly connected to it, also rotates. The rotation of the fixed cam 11 presses against the connecting block 8, causing the connecting block 8 to move and deforming the fixing spring 13. After the fixing cam 11 rotates to the point of separating from the connecting block 8, the fixed... Spring 13 returns to its original state, pushing connecting block 8 back and forth. The back-and-forth movement of connecting block 8 will cause mounting block 10 and fixing block 7 to move back and forth together, causing the striking plate 6 fixedly connected to fixing block 7 to move accordingly. During the movement of striking plate 6, it will strike brake pad 2, causing brake pad 2 to undergo slight deformation. This causes the heat dissipation holes to continuously contract and expand, forming a breathing state for heat dissipation. Moreover, when fixing ring 3 rotates, the rotating fan blade 5 fixedly sleeved on fixing ring 3 will also rotate, generating wind to further cool brake pad 2.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
