Therefore, an anti-fatigue brake drum is required. The anti-fatigue brake drum can avoid the deterioration of the braking effect caused by metal fatigue and improve the braking effect.

[0004] In the prior art, decelerating a moving vehicle relies on the driver stepping on the brake, and the speed of the wheel is reduced by the friction between the brake shoe and the brake drum. However, due to stepping on the brake for a long time, the brake drum will continuously be subjected to friction, resulting in excessive temperature, leading to metal fatigue and causing brake failure, resulting in inevitable traffic accidents. Summary of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 2 And Figure 5 , an embodiment provided by the present utility model: an anti-fatigue brake drum, including a drum brake main body 1 and a back assembly 7. A groove 3 is provided inside the drum brake main body 1. First sliding grooves 4 are provided around the inner wall of the groove 3. Second sliding grooves 19 are provided around the outside of the groove 3. A sliding rod 5 is slidably connected inside the first sliding groove 4. The other end of the sliding rod 5 is slidably connected inside the second sliding groove 19. A rotating rod 6 is fixedly connected to the middle of the sliding rod 5. A fan 8 is rotatably connected to the middle of the outer wall of the rotating rod 6. A connecting mechanism 2 is installed on the outer wall of the back assembly 7. The connecting mechanism 2 connects the drum brake main body 1 and the back assembly 7; Particle protrusions 9 are provided on the inner wall of the drum brake main body 1. The particle protrusions 9 are provided at equal intervals on the inner wall of the drum brake main body 1;

[0033] Specifically, during the driving of the vehicle, the continuous rotation of the wheels will drive the connected brake drum to rotate together. During this process, the fan 8 will be affected by an external force due to the rotation of the brake drum and start to rotate accordingly. Due to the opening of the first chute 4 and the second chute 19, under the restrictive action of the rotating rod 6 and the guiding of the sliding rod 5, the fan 8 can slide back and forth inside the first chute 4 and the second chute 19, enabling the effective circulation of the gas inside the brake drum groove 3, thereby accelerating the heat dissipation. In this way, the braking effect of the vehicle is enhanced, ensuring the driving safety and the efficient operation of the braking system. At the same time, the brake drum itself has good anti-fatigue performance, reducing traffic accidents caused by vehicle braking failure. The particle protrusions 9 can effectively increase the friction inside the brake drum and enhance the braking effect.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.

[0035] Specifically, during the connection process of the brake drum and the back assembly 7, the second ring 203 is engaged with the first ring 201 by using the circular groove 202 pre-opened on the outer wall of the first ring 201, and the threaded connection between the first ring 201 and the second ring 203 is realized by using the threaded rings 204 pre-opened on the outer wall of the second ring 203. To further ensure the reliability of the connection, the bolt 206 is rotated to threadedly connect the bolt 206 with the nut 205 fixedly connected to the outer wall of the second ring 203. At this time, the connection effect between the brake drum and the back assembly 7 is further enhanced, ensuring the stability and safety of the overall structure. Through the expansion of the brake shoe 10, the brake pad 11 contacts the brake drum, thereby decelerating the brake drum and generating a braking effect.

[0036] Refer to Figure 2 and Figure 4 As shown in FIGS.

[0037] Specifically, the brake shoe 10 is limited by the fixing plate 13 , and the brake shoe 10 is fixed by the fixing bolt 12 . After the brake shoe 10 is expanded, the brake shoe 10 is restored to its original position by the action of the pull-back spring 16 .

[0038] Reference Figure 2 and Figure 3 A hydraulic assembly 14 is installed on the top of the front side of the outer wall of the back assembly 7, and hydraulic rods 15 are installed on the left and right sides of the outer wall of the hydraulic assembly 14; a rubber ring 17 is installed inside the circular groove 202, and a rubber ring 2 18 is installed in the middle of the rear side of the outer wall of the circular ring 203;

[0039] Specifically, through the action of the hydraulic assembly 14, the hydraulic rod 15 is expanded to both sides, so that the brake shoe 10 can expand outward, and the rubber ring 17 and the rubber ring 2 18 can strengthen the connection between the brake drum and the back assembly 7 to achieve a sealing effect.

[0040] Working principle: During the driving process of the car, the rotation of the wheel will drive the rotation of the brake drum. Under this effect, the fan 8 starts to rotate due to the external force. Due to the opening of the slide groove 1 4 and the slide groove 2 19, the fan 8 will slide forward and backward along the slide groove 1 4 and the slide groove 2 19 under the limit of the rotating rod 6 and the drive of the sliding rod 5, so that the gas inside the brake drum groove 3 can circulate, the heat can be dissipated faster, and the braking effect of the car can be enhanced. At the same time, the brake drum is made of high-alloy cast iron, and the brake drum itself has good fatigue resistance, which greatly enhances the braking effect of the car during driving and reduces traffic accidents caused by brake failure of the car.

[0041] When the brake drum and the back component 7 are connected, the ring 203 is engaged through the circular groove 202 opened on the outer wall of the ring 1 201, and the ring 1 201 and the ring 2 203 are threadedly connected through the threaded ring 204 opened on the outer wall of the ring 203. After the connection, the bolt 206 is rotated to thread the bolt 206 and the nut 205 fixedly connected to the outer wall of the ring 203, thereby further enhancing the connection effect between the brake drum and the back component 7.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
