During long-term use, the connecting parts fixed between the disc brake and the hub are prone to deformation and loosening. Moreover, when overhauling or replacing the disc brake, it is inconvenient to separate the disc brake from the hub, which is time-consuming and laborious, reducing work efficiency and thus failing to achieve the best use effect.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0022] Refer to Figures 1-5 , a disc brake hub provided by the present invention includes a hub body 1. Retaining rings 2 are fixedly connected to both sides of the outer wall of the hub body 1. When installing a tire on the hub body 1 through the retaining rings 2, the two sides of the tire are blocked and limited. Reinforcing ribs 3 are fixedly connected to the periphery of the inner wall of the hub body 1. When the hub body 1 is under greater pressure, the reinforcing ribs 3 can prevent deformation. A fixing mechanism 4 is provided at the center of the outer wall of the hub body 1, and a mounting disc 5 is fixedly installed at the center of the inner wall of the hub body 1. A through hole 6 is opened at the center of the inner wall of the mounting disc 5, and bolt holes 7 are opened around the outer wall of the mounting disc 5. One end of the reinforcing rib 3 is fixedly connected to the outer wall of the mounting disc 5, and the other end of the reinforcing rib 3 is fixedly connected to the inner side wall of the hub body 1.

[0023] The fixing mechanism 4 includes a brake disc 41. A brake caliper support 42 is fixedly connected to the outer side wall of the brake disc 41. Limiting grooves 43 are opened around the outer wall of the brake caliper support 42. A mounting mechanism 44 is provided on the outer side wall of the brake caliper support 42. A positioning bolt 45 passes through the inner wall of the mounting mechanism 44. A washer 46 is sleeved on the outer wall of the positioning bolt 45. Fixing bolts 47 pass through the periphery of the outer wall of the mounting mechanism 44. A stud 48 is provided on the outer side wall of the mounting mechanism 44, and a nut 49 is provided on the outer wall of the stud 48.

[0024] The mounting mechanism 44 includes a positioning disk 441. Around the outer wall of the positioning disk 441, clamping blocks 442 are fixedly connected. At the center of the inner wall of the positioning disk 441, a limiting sleeve 443 is provided. Inside the inner wall of the limiting sleeve 443, a dust-proof ring 444 is provided. Around the outer wall of the positioning disk 441, positioning holes 445 are opened. The positioning bolts 45 pass through the limiting sleeve 443 and penetrate the through holes 6. The fixing bolts 47 pass through the positioning holes 445 and penetrate the bolt holes 7, respectively, to support and fix the center and the periphery of the hub body 1. Then, by screwing the screw sleeve 48 and the nut 49, the hub body 1 is locked and connected to the positioning disk 441, making it integrated with the brake disk 41. The positioning disk 441 is engaged with the brake caliper support 42 through the clamping blocks 442, which facilitates the quick separation of the disc brake and the hub during the inspection, replacement, disassembly, or assembly of the disc brake. The positioning disk 441 is engaged with the limiting groove 43 through the clamping blocks 442, and the outer side wall of the positioning disk 441 is correspondingly installed with the outer wall of the mounting disk 5.

[0025] Working principle: When installing the wheel belt on the hub body 1, the retaining ring 2 blocks and limits both sides of the wheel belt. When the hub body 1 is under relatively large pressure, the reinforcing ribs 3 can prevent deformation. The positioning bolts 45 pass through the limiting sleeve 443 and penetrate the through holes 6. The fixing bolts 47 pass through the positioning holes 445 and penetrate the bolt holes 7, respectively, to support and fix the center and the periphery of the hub body 1. Then, by screwing the screw sleeve 48 and the nut 49, the hub body 1 is locked and connected to the positioning disk 441, making it integrated with the brake disk 41. The positioning disk 441 is engaged with the brake caliper support 42 through the clamping blocks 442, which facilitates the quick separation of the disc brake and the hub during the inspection, replacement, disassembly, or assembly of the disc brake.
