[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0028] This embodiment mainly describes the structure of a high-strength gear ring easy-to-assemble automobile wheel hub, as follows:

[0029] like Figures 1-9 As shown, a high-strength gear ring 8 easy-to-assemble automobile wheel hub includes a hub body 1 and a spoke installed in the hub body 1, a connecting seat 3 connected to the vehicle is provided on the spoke, and a fixing assembly and a connecting hole 31 are provided on the connecting seat 3, and a gear ring 8 rotatably installed on the connecting seat 3, and a first bearing 9 is provided between the connecting seat 3 and the gear ring 8, and the inner ring of the first bearing 9 is interference-connected with the mounting ring 81, which facilitates the rotation of the gear ring 8 on the connecting seat 3. Finally, a cover 6 for covering the fixing assembly is provided on the connecting seat 3, so that impurities and dirt can be prevented from entering the fixing assembly when the wheel hub is in use, thereby facilitating the use of the fixing assembly;

[0030] Among them, the gear ring 8 includes a mounting ring 81 rotatably connected to the connecting seat 3 and a plurality of racks 82 mounted on the inner wall of the mounting ring 81, and the plurality of racks 82 are all arranged in an arc shape, so that the racks 82 can better fit the inner wall of the mounting ring 81, and the racks 82 are connected to the mounting ring 81 by bolts 85, thereby facilitating the disassembly and assembly of the racks 82. In this way, when the gear ring 8 needs to be replaced due to wear during use, it is convenient to replace the racks 82. The racks 82 are arranged in plurality, so when the rack 82 at a certain position is worn, only the rack 82 needs to be replaced, thereby reducing waste of materials. Fee, and the setting of the mounting ring 81 can ensure the strength of the ring gear 8, and then a connecting groove 83 matching the mounting ring 81 is opened on the outer wall of the rack 82, and the mounting ring 81 is located in the connecting groove 83, so that the connection between the rack 82 and the mounting ring 81 can be more stable; and a plurality of teeth 84 are evenly arranged on the inner wall of the rack 82, and a corrosion-resistant layer 841 is provided on the surface of the tooth body 84, thereby improving the corrosion resistance of the tooth body 84, and then a ceramic layer 842 is provided on the surface of the corrosion-resistant layer 841, which can improve the wear resistance of the tooth body 84, thereby extending the service life of the tooth body 84.

[0031] Furthermore, the connecting seat 3 is provided with a receiving groove 5 on the side wall close to the vehicle side, so that when the hub body 1 is installed on the vehicle, the hub body 1 can better fit with the output end of the vehicle.

[0032] The fixing assembly includes a plurality of mounting holes 12 opened on the connecting seat 3, and the mounting holes 12 and the connecting holes 31 are not only coaxially arranged but also interconnected, and a second bearing 11 is provided in each of the plurality of mounting holes 12, and then a screw sleeve 10 is respectively installed in each of the mounting holes 12, and the outer wall of the screw sleeve 10 is respectively interference-connected with the inner ring of the second bearing 11, and finally, a gear 7 capable of meshing with the ring gear 8 is respectively provided on the outer wall of the plurality of screw sleeves 10, and a polygonal adjustment groove 71 is respectively opened on the outer wall of the wheel, wherein the polygonal adjustment groove 71 is a hexagonal adjustment groove 71;

[0033] In this way, when connecting the wheel hub to the vehicle, first align the connecting hole 31 on the wheel hub with the screw on the vehicle, then push the wheel hub to insert the screw into the connecting hole 31 until it abuts against the screw sleeve 10, and then insert the Allen wrench into any adjusting slot 71 and rotate it. In this way, the screw sleeve 10 connected to the gear 7 can be rotated in the mounting hole 12 due to the cooperation with the second bearing 11, so the screw can enter the screw sleeve 10 as the screw sleeve 10 rotates, and because multiple gears 7 are respectively engaged with the ring gear 8, and the ring gear 8 is rotatably connected to the connecting seat 3, when one gear 7 is rotated, multiple gears 7 can be driven to rotate simultaneously through the ring gear 8. In this way, when disassembling and assembling the wheel hub, only one gear 7 needs to be screwed, which facilitates the disassembly and assembly of the wheel hub.

[0034] The spokes include a support ring 2 installed in the hub body 1 and a plurality of support frames 4 circumferentially installed on the connecting seat 3, and the support frames 4 are respectively connected to the support ring 2 at one end away from the connecting seat 3, so that the supporting effect of the spokes on the hub body 1 is improved, thereby improving the strength of the hub, wherein the support frames 4 include two support plates 41 obliquely installed in the hub body 1, and one end of the support plate 41 is connected to the connecting seat 3 and the other end is connected to the support ring 2, and then two K-shaped reinforcement frames 42 are arranged on the connecting seat 3 between the two support plates 41, and the two reinforcement frames 42 are arranged to abut each other, so that the support effect of the hub on the hub body 1 can be further improved by the coordinated use of the support plates 41 and the reinforcement frames 42, thereby further improving the strength of the hub.
