Description

Technical Field

[0001] This utility model relates to the field of brake shoe technology, and in particular to a brake shoe heat dissipation structure. Background Technology

[0002] Brake shoes are a key component of a car's braking system. They typically refer to the friction pairs in a drum brake, used to work with the brake drum to achieve the braking function. When the driver presses the brake pedal, the brake shoes press firmly against the brake drum through the brake control mechanism, using the friction between them to slow down the rotation of the wheels and ultimately bring the vehicle to a stop.

[0003] Brake shoes effectively brake the wheels. During braking, intense friction can cause the temperature of the brake shoes to rise rapidly. Existing brake shoe structures are simple and cannot effectively dissipate heat. Prolonged high temperatures will shorten the service life of the brake shoes and increase costs. Therefore, a brake shoe heat dissipation structure is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing brake shoe structures, such as their simple design, ineffective heat dissipation, and the fact that prolonged high temperatures shorten the service life of the brake shoes, leading to increased costs. Therefore, this invention proposes a brake shoe heat dissipation structure.

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

[0006] A brake shoe heat dissipation structure includes an arc-shaped plate, a support plate on one side of the arc-shaped plate, connecting rings fixedly connected to both ends of the support plate, heat dissipation holes on the support plate, a first heat-conducting plate and a second heat-conducting plate respectively connected to both sides of the support plate, receiving cavities formed inside the first heat-conducting plate and the second heat-conducting plate, a first connecting pipe fixedly connected to one side of the first heat-conducting plate, and a second connecting pipe fixedly connected to one side of the second heat-conducting plate.

[0007] Preferably, a liquid inlet is provided on one side of the first heat-conducting plate, and a sealing cap is connected to the liquid inlet. Both ends of the first heat-conducting plate and the second heat-conducting plate are fixedly connected to a first mounting plate.

[0008] Preferably, the first mounting plate has a first fixing hole, and the support plate has second fixing holes at both ends. Fixing bolts are connected in the first fixing hole and the second fixing hole, and the fixing bolts are threaded with screws.

[0009] Preferably, a sealing plate is fixedly connected to one end of the first connecting pipe, and a sealing groove is opened at one end of the second connecting pipe, with the sealing plate located inside the sealing groove.

[0010] Preferably, a mounting groove is provided on one side of the arc-shaped plate, and a second mounting plate is fixedly connected to one side of the support plate, the second mounting plate being located within the mounting groove.

[0011] Preferably, the side of the arc-shaped plate is provided with a first threaded hole, and the side of the second mounting plate is provided with a second threaded hole, and a long bolt is internally threaded into the first threaded hole and the second threaded hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When in use, coolant can be added to the cavity of the first heat-conducting plate. The coolant then enters the second heat-conducting plate through the first and second connecting pipes in the heat dissipation holes. The first and second heat-conducting plates simultaneously cool and dissipate heat on both sides of the support plate, effectively dissipating heat and avoiding prolonged high temperatures. This extends the service life of the brake shoes and effectively saves costs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-4 A brake shoe heat dissipation structure includes an arc-shaped plate 1, a support plate 2 on one side of the arc-shaped plate 1, connecting rings fixedly connected to both ends of the support plate 2, heat dissipation holes 3 on the support plate 2, a first heat-conducting plate 4 and a second heat-conducting plate 5 respectively connected to both sides of the support plate 2, receiving cavities opened inside the first heat-conducting plate 4 and the second heat-conducting plate 5, a first connecting pipe 6 fixedly connected to one side of the first heat-conducting plate 4, and a second connecting pipe 7 fixedly connected to one side of the second heat-conducting plate 5.

[0021] Coolant is added to the cavity of the first heat-conducting plate 4. The coolant enters the second heat-conducting plate 5 through the first connecting pipe 6 and the second connecting pipe 7 in the heat dissipation hole 3. The first heat-conducting plate 4 and the second heat-conducting plate 5 simultaneously cool down both sides of the support plate 2.

[0022] Furthermore, a liquid inlet 8 is provided on one side of the first heat-conducting plate 4, and a sealing cap 9 is connected to the liquid inlet 8. Both ends of the first heat-conducting plate 4 and the second heat-conducting plate 5 are fixedly connected to the first mounting plate 10.

[0023] The first mounting plate 10 has a first fixing hole, and the support plate 2 has second fixing holes at both ends. Fixing bolts 11 are connected in the first fixing hole and the second fixing hole, and nuts are threaded onto the fixing bolts 11.

[0024] Coolant is added into the receiving cavity through the liquid inlet 8, and then sealed through the sealing cap 9.

[0025] The first heat-conducting plate 4 and the second heat-conducting plate 5 are fixed to both sides of the support plate 2 using fixing bolts 11 and nuts through the first fixing hole on the first mounting plate 10 and the second fixing hole on the support plate 2.

[0026] Furthermore, a sealing plate is fixedly connected to one end of the first connecting pipe 6, and a sealing groove is opened at one end of the second connecting pipe 7, with the sealing plate located in the sealing groove.

[0027] When one end of the first connecting pipe 6 and the second connecting pipe 7 are connected together, the sealing plate and the sealing groove seal the connection between the first connecting pipe 6 and the second connecting pipe 7 to prevent coolant from flowing out from the connection between the first connecting pipe 6 and the second connecting pipe 7.

[0028] Furthermore, an installation groove 12 is provided on one side of the arc plate 1, and a second installation plate 13 is fixedly connected to one side of the support plate 2. The second installation plate 13 is located in the installation groove 12.

[0029] The side of the arc plate 1 is provided with a first threaded hole 14, and the side of the second mounting plate 13 is provided with a second threaded hole 15. The first threaded hole 14 and the second threaded hole 15 are internally threaded with long bolts 16.

[0030] The arc plate 1 and the support plate 2 can be produced separately. After production, they are assembled so that the second mounting plate 13 enters the mounting groove 12. Long bolts 16 are screwed into the first threaded hole 14 and the second threaded hole 15 for fixation. Multiple long bolts 16 fix the arc plate 1 and the second mounting plate 13, and the fixing effect is good.

[0031] The working principle of this utility model:

[0032] Open the sealing cover 9 and add coolant into the receiving cavity of the first heat-conducting plate 4 through the liquid inlet 8. The coolant enters the second heat-conducting plate 5 through the first connecting pipe 6 and the second connecting pipe 7 in the heat dissipation hole 3. The first heat-conducting plate 4 and the second heat-conducting plate 5 simultaneously cool down both sides of the support plate 2, which can effectively dissipate heat and has a better heat dissipation effect. This avoids prolonged high temperature, extends the service life of the brake shoes, and effectively saves costs.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
