Description

Technical Field

[0001] This utility model relates to the field of brake shoe technology, and in particular to an assembled brake shoe assembly. Background Technology

[0002] Brake shoes are a key component of drum brakes. Their function is to work with the brake drum to enable the vehicle to brake. The effectiveness of vehicle braking depends on the brake shoes. Brake shoes are classified as leading shoes and trailing shoes according to whether their rotation direction when opening is consistent with the rotation direction of the brake drum. Among them, leading shoes have a braking force amplification function.

[0003] To this end, patent CN203477135U discloses a brake shoe assembly, including a brake shoe and a friction pad. The brake shoe includes a liner and a rib, with a return spring hook hole on the rib and a liner rivet hole on the liner. The liner and the rib are welded together. The friction pad has a friction pad rivet hole corresponding to the liner rivet hole and an anti-wear platform at the edge. The friction pad is riveted to the brake shoe. This utility model reduces the production cost and weight of the brake shoe assembly and improves the reliability and durability of the brake shoe assembly.

[0004] In existing brake shoe assemblies, the friction pads are prone to wear during use. Once the wear is severe, it is difficult to remove and replace them, making replacement challenging and affecting their performance. Utility Model Content

[0005] The purpose of this invention is to provide an assembled brake shoe assembly to solve the defect of an existing assembled brake shoe assembly that makes it inconvenient to replace the friction pads.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an assembled brake shoe assembly, including brake shoes, brake ribs installed on the inner side of the brake shoes, friction pads provided on the outer side of the brake shoes, and a disassembly and assembly structure provided on the brake shoes. The disassembly and assembly structure includes an assembly baffle installed on the friction pads, an assembly plate installed on the assembly baffle, limiting blocks evenly installed on the inner side of the assembly plate, and fixing bolts symmetrically installed on the brake shoes. An assembly groove that mates with the assembly plate is opened inside the brake shoes, and a limiting groove that mates with the limiting block is opened on the inner wall of the assembly groove.

[0007] Preferably, the mounting plate has threaded holes that mate with fixing bolts.

[0008] The above structure allows for the fixing bolts to secure the assembly plates.

[0009] Preferably, the limiting blocks are arranged at equal intervals on the inner side of the mounting plate.

[0010] The above structure improves the limiting effect on the assembly plates.

[0011] Preferably, the width of the assembly baffle is greater than the width of the assembly groove.

[0012] With the above structure, the assembly baffle can shield and protect the assembly slot.

[0013] Preferably, one end of the brake shoe is provided with heat dissipation holes.

[0014] The above structure allows the heat from the friction pads to be dissipated.

[0015] Preferably, the inner side of the friction pad is uniformly provided with slots, and the outer surface of the brake shoe is uniformly provided with blocks.

[0016] Preferably, the card block and the card slot cooperate to form an engaging structure.

[0017] The above structure can limit the friction plate to a certain extent, thereby improving the stability of the friction plate installation.

[0018] The advantages of the assembled brake shoe assembly provided by this utility model are as follows:

[0019] The disassembly and assembly structure allows for quick disassembly and assembly of the friction pads, facilitating the replacement of severely worn friction pads. When assembling the friction pads, the locking block engages with the slot, which provides a certain degree of restraint on the friction pads, improving the stability of the friction pad installation and preventing relative sliding between the friction pads and brake shoes.

[0020] By removing the fixing bolts through the designed disassembly and assembly structure, the fixing restriction on the assembly plate is released. The assembly baffle is pulled, and the assembly plate moves away from the brake shoe until the assembly plate is removed from the assembly slot. This allows the friction pad, the assembly plate, and the brake shoe to be separated, thus achieving the purpose of replacing the friction pad.

[0021] Furthermore, by setting limit blocks and limit grooves, when assembling the friction plate, the limit blocks are inserted into the limit grooves, which can play a certain limiting role on the assembly plate and improve its installation stability. The assembly plate and assembly baffle can be heat-conducting materials, which can conduct the heat of the friction plate and dissipate it through the heat dissipation holes.

[0022] By using the locking blocks, when assembling the friction pads, the blocks engage with the slots, which can limit the movement of the friction pads, improve the stability of the friction pad installation, and prevent the friction pads from sliding relative to the brake shoes.

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.

[0030] Please see Figures 1-5 The present invention provides an assembled brake shoe assembly, including brake shoe 3.

[0031] Reference Figures 1-5 As shown, brake ribs 2 are installed on the inner side of brake pad 3, and heat dissipation holes 5 are evenly opened at one end of brake pad 3 to dissipate the heat of friction pad 4. Friction pad 4 is provided on the outer side of brake pad 3, and slots 6 are evenly opened on the inner side of friction pad 4. Blocks 7 are evenly installed on the outer surface of brake pad 3. Blocks 7 cooperate with slots 6, and blocks 7 and slots 6 form a locking structure to limit the friction pad 4.

[0032] The brake shoe 3 is provided with a disassembly and assembly structure 1, which includes an assembly baffle 12 installed on the friction pad 4, an assembly plate 13 installed on the assembly baffle 12, a threaded hole on the assembly plate 13 that mates with the fixing bolt 11 so that the fixing bolt 11 can fix the assembly plate 13, a limiting block 14 evenly installed on the inner side of the assembly plate 13, the limiting block 14 being evenly spaced on the inner side of the assembly plate 13, the evenly spaced limiting block 14 enhancing the limiting effect on the assembly plate 13, and a fixing bolt 11 symmetrically installed on the brake shoe 3. The brake shoe 3 has an assembly groove 15 that mates with the assembly plate 13 inside, the width of the assembly baffle 12 is greater than the width of the assembly groove 15, and a limiting groove 16 that mates with the limiting block 14 is opened on the inner wall of the assembly groove 15.

[0033] During assembly, the mounting plate 13 is pushed into the mounting groove 15, the limiting block 14 engages with the limiting groove 16, and the locking block 7 engages with the locking groove 6 until the mounting baffle 12 contacts the brake shoe 3. The fixing bolt 11 is then tightened to fix the mounting plate 13 and the brake shoe 3 together, completing the installation of the friction pad 4. The limiting block 14 engages with the limiting groove 16, which can limit the mounting plate 13 to a certain extent and improve its installation stability. The mounting plate 13 and the mounting baffle 12 can be heat-conducting materials, which can conduct the heat of the friction pad 4 and dissipate it through the heat dissipation hole 5. The locking block 7 engages with the locking groove 6, which can limit the friction pad 4 to a certain extent and improve the installation stability of the friction pad 4, preventing the friction pad 4 and the brake shoe 3 from sliding relative to each other.

[0034] During disassembly, remove the fixing bolts 11 to release the fixing restriction on the mounting plate 13, pull the mounting baffle 12, and move the mounting plate 13 away from the brake shoe 3 until the mounting plate 13 is removed from the mounting groove 15. This will separate the friction plate 4, the mounting plate 13 and the brake shoe 3, thus achieving the purpose of replacing the friction plate 4.
