[0031] The rotating column 31 is rotatably installed at one end of the hub column 11, the rotating disk 32 is rotatably installed inside one end of the hub column 11, the snap-fit bolt 33 is movably sleeved inside the movable groove 14, and the second limiting hole 36 inside the rotating disk 32 and the side disk 34 corresponds to the first limiting hole 15.
[0032] like Figure 4 As shown, the brake disc assembly 2 includes a brake disc 21 and a mounting block 22. The side of the brake disc 21 is fixedly mounted to the mounting block 22. The inner wall of the brake disc 21 has multiple positioning cavities 23. One end of each positioning cavity 23 has a snap-fit groove 24. The mounting block 22 has a limiting groove 25 on the side away from the brake disc 21. Both sides of the limiting groove 25 have locking holes 26.
[0033] Among them, the brake disc 21 is movably sleeved on the outer surface of the wheel hub pillar 11, the positioning cavity 23 is embedded in the outer surface of the inner insert block 13, and the snap-fit groove 24 is sleeved on the outer surface of the snap-fit bolt 33.
[0034] The positioning cavity 23 is inserted into the outer surface of the inner block 13 to prevent the brake disc assembly 2 from rotating on the outer surface of the wheel hub post 11, thereby maintaining the fixation between the wheel hub assembly 1 and the brake disc assembly 2.
[0035] like Figures 5-6 As shown, the fixing device 4 includes a fixing block 41. Multiple connecting plates 42 are fixedly installed on the outer surface of the fixing block 41.

[0036] The connecting plate 42 and the positioning block 43 are respectively embedded in the positioning groove 35 and the limiting groove 25 to fix the brake disc assembly 2 and the snap-fit assembly 3. The positioning bolt 46 is inserted into the second limiting hole 36 and the first limiting hole 15 to prevent the brake disc assembly 2 and the snap-fit assembly 3 from rotating on the outer surface of the wheel hub assembly 1. At the same time, the snap-fit bolt 33 is snapped into the snap-fit groove 24 to complete the fixation of the brake disc assembly 2 and the wheel hub assembly 1.
[0037] The connecting plate 42 is movably fitted with a movable rod 47. Both ends of the positioning block 43 are movably fitted with fixed bolt rods 48. One end of the movable rod 47 is movably fitted inside the fixed block 41. The opposite side of the two fixed bolt rods 48 is an inclined surface. A connecting block 49 is fixedly installed on the side of the two fixed bolt rods 48 away from the fixed block 41. The connecting block 49 is movably fitted inside the positioning block 43.

[0038] With inclined surfaces on opposite sides of the two fixed bolt rods 48, when the frustum insert 44 is inserted into the fixed block 41, the inclined surfaces of the frustum insert 44 push the movable rod 47 to move outward. The movable rod 47 is inserted between the two fixed bolt rods 48. The inclined surfaces of the fixed bolt rods 48 cause the fixed bolt rods 48 to move outward at both ends of the positioning block 43 and engage inside the bolt holes 26, thus completing the fixation of the brake disc assembly 2 and the engagement assembly 3.
[0039] like Figure 7 As shown, the disassembly tool 5 includes a fixing plate 51, a push rod 52 is fixedly installed at one end of the fixing plate 51, a side block 53 is fixedly installed on the side of the fixing plate 51, a rotating bolt 54 is fixedly installed at one end of the side block 53, the side block 53 is embedded in the positioning groove 35, and the rotating bolt 54 is inserted into the second limiting hole 36 inside the side plate 34.
[0040] Using the disassembly tool 5, the side block 53 is fitted into the positioning groove 35. The bolt 54 is rotated and inserted into the second limiting hole 36 in the side plate 34. By rotating the push rod 52, the disassembly tool 5 can rotate the locking assembly 3 through the lever principle, thereby facilitating the disassembly and assembly of the wheel hub assembly 1 and the brake disc assembly 2.
[0041] The working process of this utility model is as follows:
[0042] During installation, the brake disc 21 is fitted onto the outer surface of the wheel hub post 11, so that the positioning cavity 23 passes through the outer surface of the locking bolt 33. One end of the positioning cavity 23 is fitted onto the outer surface of the inner insert 13, and the side block 53 is fitted into the inside of the positioning groove 35. The locking bolt 54 is rotated and inserted into the second limiting hole 36 in the side plate 34. By rotating the push rod 52, the locking assembly 3 rotates inside the wheel hub post 11 through the lever principle. The rotating disk 32 rotates, so that the locking bolt 33 is inserted into the inside of the locking groove 24, thus completing the assembly of the brake disc assembly 2 and the wheel hub assembly 1. At this time, the second limiting hole 36 inside the rotating disk 32 and the side plate 34 are located on both sides of the first limiting hole 15.
[0043] The positioning bolts 46 on the side of the connecting plate 42 are inserted into the second limiting hole 36 and the first limiting hole 15, and the connecting plate 42 and the positioning block 43 are engaged in the positioning groove 35 and the limiting groove 25 to prevent the brake disc assembly 2 from rotating on the outer surface of the wheel hub assembly 1. Then, by rotating the fixing bolt 45, the fixing bolt 45 is fixedly installed at one end of the wheel hub column 11 through the rotating column 31. As the fixing bolt 45 is gradually tightened, the frustum insert 44 moves into the interior of the fixing block 41, thereby causing the movable rod 47 to move outward. The movable rod 47 is inserted between the two fixing bolt rods 48. Using the inclined surface of the fixing bolt rod 48, the fixing bolt rod 48 moves outward at both ends of the positioning block 43 and engages in the interior of the bolt hole 26, thus completing the fixation of the brake disc assembly 2 and the engaging assembly 3.
