Abstract
Description
Technical Field
[0001] This utility model belongs to the field of brake pad technology, specifically relating to an assembled automotive brake pad. 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 blocks withstand external pressure, generating friction to achieve vehicle deceleration. Automotive brake pads generally consist of a steel plate, an adhesive layer, and friction blocks. Currently, the main problem with automotive brake pads is that overheating of the friction blocks leads to reduced friction. To solve this problem, holes are often made in the friction blocks for heat dissipation. However, since the friction blocks are connected by the adhesive layer, when the friction blocks wear out, the entire brake pad needs to be replaced, resulting in resource waste. Utility Model Content
[0003] The purpose of this utility model is to provide an assembled automotive brake pad with a simple structure. The friction block can be installed through a fixing mechanism, making the friction block replaceable. When the fixing mechanism is fixed, it forms a through gap on the friction block, which enhances the heat dissipation of the friction block. It is highly practical and suitable for widespread application.
[0004] This utility model provides the following technical solution: an assembled automotive brake pad, comprising an outer fixing plate, a steel plate, and a friction block. The steel plate is fixed with an array of insertion sleeves facing the friction block. The steel plate has a through threaded hole at the insertion sleeve. The insertion sleeve has a converging section offset inward. The insertion sleeve has an outwardly protruding push block fixed at the front end of the converging section. The insertion sleeve has a partition gap that divides the insertion sleeve into multiple segments arranged in a circumferential array around the threaded hole.
[0005] The friction block has a through hole at the corresponding insertion sleeve. A limiting hole is provided on the side of the through hole away from the steel plate. The center of the limiting hole coincides with the center of the through hole, and its diameter is larger than the diameter of the through hole.
[0006] The fixing plate is provided with a fixing bolt at the corresponding threaded hole. The push thread on the inner wall of the threaded hole extends to the inner wall of the insertion sleeve. The push thread is connected to the raised thread of the fixing bolt.
[0007] Preferably, the insertion sleeve is connected to the inner wall of the threaded hole, the insertion sleeve is elastic, and the cross-sectional diameter of the fixing bolt matches the threaded hole.
[0008] Preferably, a pad is fixedly provided on the side of the steel plate facing the friction block. The pad is an elastic strip. When the pad is sandwiched between the steel plate and the friction block, the push block is located at the limiting hole.
[0009] Preferably, the jacking block has an inclined pressing surface on the side facing the limiting hole, and the inclined pressing surface is slidably connected to the edge of the limiting hole.
[0010] The beneficial effects of this utility model are: simple structure, friction blocks can be installed through a fixing mechanism, making the friction blocks replaceable, and the fixing mechanism forms a through gap on the friction blocks during fixing, enhancing heat dissipation of the friction blocks, making it highly practical, as detailed below:
[0011] (1) This utility model is equipped with an insertion sleeve. When installing the brake pad, the insertion sleeve is pressed into the corresponding through hole. At this time, the edge of the limiting hole is located at the front end of the inclined pressing surface of the push block. The fixing bolt of the outer fixing plate is driven into the corresponding threaded hole. During the driving of the fixing bolt, its front end is pressed against the constriction section of the insertion sleeve, which opens the constriction section. During the opening of the constriction section, the push block moves outward. The inclined pressing surface of the push block squeezes the edge of the limiting hole, so that the steel plate and the friction block are close together and the pad is pressed tightly. After the fixing bolt is fully inserted, it is fixed in the through hole, so that the outer fixing plate, the steel plate and the friction block are fixed together to form a brake pad. After the friction block is worn, the fixing bolt can be removed to replace the friction block. The outer fixing plate and the steel plate can be reused.
[0012] (2) This utility model is provided with a partition gap, which allows the converging section to open outward. When the friction block is working, it is a cavity at the limiting hole, and the insertion sleeve is located inside the limiting hole. The limiting hole is a through-hole at the partition gap, so that a through hole is formed on the friction block. The steel plate and the friction block are spaced by a pad strip to achieve the purpose of opening a hole on the friction block for heat dissipation. Attached Figure Description

[0022] See Figure 1-3 An assembled automotive brake pad includes an outer fixing plate 1, a steel plate 2, and a friction block 3. An array of insertion sleeves 4 are fixed on the side of the steel plate 2 facing the friction block 3, and the steel plate 2 and the friction block 3 are joined by the insertion sleeves 4. The steel plate 2 has a through threaded hole 12 at the insertion sleeve 4, and the insertion sleeve 4 is connected to the inner wall of the threaded hole 12 for the insertion of the same bolt. The insertion sleeve 4 has a converging section 10, which is offset inward so that the push block 11 connected to it can be inserted into the friction block 3. The insertion sleeve 4 has an outwardly protruding push block 11 fixed at the front end of the converging section 10. The insertion sleeve 4 has a partition gap 5 and is elastic. The partition gap 5 divides the insertion sleeve 4 into multiple segments arranged in a circumferential array around the threaded hole 12. A pad 6 is fixed on the side of the steel plate 2 facing the friction block 3. The pad 6 is an elastic strip that provides a gap between the steel plate 2 and the friction block 3.
[0023] See Figure 2-3The friction block 3 has a through hole 8 corresponding to the insertion sleeve 4. The through hole 8 has a limiting hole 7 on the side away from the steel plate 2. The center of the limiting hole 7 coincides with the center of the through hole 8, and its diameter is larger than that of the through hole 8. By fastening the push block 11 to the limiting hole 7, the steel plate 2 and the friction block 3 are fixed. When the pad 6 is sandwiched between the steel plate 2 and the friction block 3, the push block 11 is located at the limiting hole 7. The push block 11 has an inclined pressure surface 14 on the side facing the limiting hole 7. The inclined pressure surface 14 is slidably connected to the edge of the limiting hole 7. When the insertion sleeve 4 opens outward, the push block 11 is inserted into the limiting hole 7. During the insertion process, the inclined pressure surface 14 squeezes the edge of the limiting hole 7, making the steel plate 2 and the friction block 3 closer together and pressing the pad 6 tightly.
[0024] See Figure 1-2 A fixing bolt 9 is provided on the fixing plate 1 at the corresponding threaded hole 12. The push thread 13 on the inner wall of the threaded hole 12 extends to the inner wall of the insertion sleeve 4. The push thread 13 is connected to the raised thread of the fixing bolt 9. The cross-sectional diameter of the fixing bolt 9 matches the threaded hole 12. The fixing bolt 9 is driven into the corresponding threaded hole 12 to connect the fixing plate 1 and the steel plate 2. The insertion sleeve 4 is opened by the fixing bolt 9, and the fixing bolt 9 provides support in the through hole 8.
[0025] The assembled automotive brake pads of this utility model have a simple structure. The friction blocks can be installed through a fixing mechanism, which allows the friction blocks to be replaced. When the fixing mechanism is fixed, it forms a through gap on the friction blocks, which enhances the heat dissipation of the friction blocks. It is highly practical and suitable for widespread application.
[0026] For specific usage, please refer to... Figure 1-3 When installing the brake pads, the insert sleeve 4 is pressed into the corresponding through hole 8. At this time, the edge of the limiting hole 7 is located at the front end of the inclined pressing surface 14 of the push block 11. The fixing bolt 9 of the outer fixing plate 1 is driven into the corresponding threaded hole 12. During the driving of the fixing bolt 9, its front end presses against the constriction section 10 of the insert sleeve 4, opening the constriction section 10. During the opening of the constriction section 10, the push block 11 moves outward, and the inclined pressing surface 14 of the push block 11 squeezes the edge of the limiting hole 7, so that the steel plate 2 and the friction block... 3. Press the pad 6 close to the edge. After the fixing bolt 9 is fully inserted, it is fixed in the through hole 8, which fixes the outer fixing plate 1, steel plate 2, and friction block 3 together to form a brake pad. After the friction block 3 wears, the fixing bolt 9 can be removed to replace the friction block 3. When the friction block 3 is working, it is a cavity at the limit hole 7. The insertion sleeve 4 is located in the limit hole 7. The limit hole 7 is a through hole at the partition gap 5, which forms a through hole on the friction block 3. The steel plate 2 and the friction block 3 are separated by the pad 6, which is used as a heat dissipation hole.
