Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0023] The brake hub with a wear-resistant layer disclosed in the utility model is mainly used in the scene of brake hub.
[0024] Reference Figures 1 to 5 A brake hub with a wear-resistant layer comprises: a brake hub shell 1, characterized in that a first mounting hole 2 is opened on one side of the brake hub shell 1, two mounting plates 3 are arranged inside the brake hub shell 1, brake pads 4 are arranged on the outer sides of the two mounting plates 3, the brake pads 4 are fitted with the mounting plates 3, and a positioning component is arranged between the brake pads 4 and one side of the mounting plates 3, a first through groove 12 is opened inside the brake hub shell 1, a connecting rod 15 is arranged inside the first through groove 12, two limiting plates 16 are fixedly connected to the outer side of the connecting rod 15, one end of the mounting plate 3 is rotatably connected to the outer side of the connecting rod 15, and an adjustment component is arranged inside the brake hub shell 1.
[0025] In the above technical scheme, it is taken into consideration that the friction between the traditional brake disc and the brake pad will cause the brake disc to wear, and the brake disc and brake pad need to be replaced frequently. In order to solve such problems, the specific operations are as follows: by setting a positioning component, the brake pad 4 can be installed on the mounting plate 3, so that the brake pad 4 is tightly fitted with the mounting plate 3, and the two mounting plates 3 are opened by rotating the adjusting component, and then the brake pad 4 is opened to frictionally decelerate with the tire to achieve the braking effect. By adjusting the opening distance between the brake pads 4, the friction between the brake pad 4 and the wheel can be effectively controlled, the wear rate of the brake pad 4 can be reduced, the frequency of replacing the brake pad 4 and the brake disc can be reduced, and its service life can be extended, thereby saving maintenance costs. At the same time, the brake pad 4 can be made of organic resin brake pad 4, which is inexpensive, generates relatively less braking noise during braking, causes less wear on the brake disc, and has good wear resistance.
[0026] Reference Figures 1 to 5 In a preferred embodiment, the adjustment component includes a second through slot 14, which is opened inside the brake hub shell 1, and a rotating rod 17 is rotatably connected inside the second through slot 14, and one end of the rotating rod 17 is fixedly connected to two extrusion blocks 19. The adjustment component also includes a notch 8, which is opened at the bottom of the mounting plate 3, and a roller 9 is rotatably connected inside the notch 8, and the outer side of the roller 9 conflicts with one side of the extrusion block 19. One end of the rotating rod 17 extends to the outer side of the brake hub shell 1 and is provided with a connecting rod 13, and a nut 18 is threadedly connected to one end of the rotating rod 17. The outer side of the rotating rod 17 and the inner side of the connecting rod 13 are both provided with teeth. The positioning component includes a second mounting hole 5, which is equidistantly opened inside the mounting plate 3, and a mounting block 6 is equidistantly fixedly connected to one side of the brake pad 4, and the outer side of the mounting block 6 is slidably connected to the inner side of the second mounting hole 5. A skeleton 10 is provided inside the mounting plate 3, and through holes 11 are equidistantly opened inside the skeleton 10, and double hook springs 7 are provided between the through holes 11;
[0027] In the above technical scheme, considering that the friction between the traditional brake disc and the brake pad will cause the brake disc to wear, the brake disc and the brake pad need to be replaced frequently, in order to solve such problems, the specific operation is as follows: through the swing of the connecting rod 13, the rotating rod 17 is driven to rotate, thereby driving the extrusion block 19 to rotate, so that one side of the extrusion block 19 conflicts with the roller 9, and pushes the roller 9 to one side, thereby driving the mounting plate 3 and the brake pad 4 to expand to both sides with the connecting rod 15 as the center, and contacting with the wheel to generate friction, so as to achieve the braking effect. By setting the roller 9, the extrusion block 19 can be prevented from directly contacting the mounting plate 3, and the resistance of expansion can be reduced. By setting the fan-shaped extrusion block 19, the contact force between the roller 9 and the roller 9 can be controlled, the distance between them can be adjusted, and the expansion range of the brake pad 4 can be controlled. The performance of the braking system can be adjusted, so that the braking effect always remains sensitive, better adapts to the braking needs under different driving conditions, and improves the driver's sense of control and driving safety.
[0028] Working principle: When in use, first swing through the connecting rod 13, then drive the rotating rod 17 to rotate, thereby driving the extrusion block 19 to rotate, so that one side of the extrusion block 19 conflicts with the roller 9, and pushes the roller 9 to one side, thereby driving the mounting plate 3 and the brake pad 4 to expand to both sides with the connecting rod 15 as the center, and generate friction with the wheel contact. At this time, the double hook spring 7 is in a stretched state, and the braking effect is achieved. By setting the roller 9, the extrusion block 19 can be prevented from directly contacting the mounting plate 3, and the resistance to expansion can be reduced. By setting the fan-shaped extrusion block 19, the contact force between the roller 9 and the distance between them can be controlled, and the expansion range of the brake pad 4 can be controlled. The performance of the braking system can be adjusted, so that the braking effect always remains sensitive, which is more suitable for braking needs under different driving conditions, and improves the driver's sense of control and driving safety.

[0029] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
