Embodiment 1

[0026] Refer to Figures 1-4 As shown, the present utility model discloses a fastening structure for a floating cover of an automobile wheel hub, including:

[0027] A rotating part 1, the rotating part 1 includes a turntable 11 and a bearing 12, a seat ring 111 is arranged at the center of one side of the turntable 11, and the inner ring of the bearing 12 is sleeved outside the seat ring 111;

[0028] A supporting part 2, the supporting part 2 includes a mounting seat 21 and a retaining ring 22, a snap ring 211 is arranged at the center of one side of the mounting seat 21, the side of the mounting seat 21 provided with the snap ring 211 is buckled on the side of the turntable 11 provided with the seat ring 111, and the snap ring 211 is clamped outside the outer ring of the bearing 12; the bearing 12 is in interference fit with both the seat ring 111 and the snap ring 211; the retaining ring 22 is sleeved outside the snap ring 211.

[0029] As can be seen from the above structure, the structure of the rotating part 1 in the present utility model consists of a turntable 11 and a bearing 12. Specifically, a seat ring 111 that cooperates with the bearing 12 is provided at the center of the surface of the turntable 11. The seat ring 111 is connected to the inner ring of the bearing 12, and the turntable 11 can rotate through the inner ring of the bearing 12. The mounting seat 21 of the supporting part 2 is used for mounting the bearing 12. Specifically, a snap ring 211 is provided at the center of the surface of the mounting seat 21. By snapping the snap ring 211 onto the outer ring of the bearing 12, the bearing 12 is fixed on the mounting seat 21, enabling the turntable 11 to rotate on the mounting seat 21. As a preferred solution of the present utility model, the inner ring and the outer ring of the bearing 12 are respectively installed in an interference fit with the seat ring 111 and the snap ring 211, restricting the axial and radial displacements of the bearing 12 and ensuring the stability of the installation of the bearing 12. Secondly, in the present utility model, a retaining ring 22 is sleeved outside the snap ring 211 to limit the deformation of the snap ring 211 and the seat ring 111, so that an interference fit state is always maintained between the outer ring of the bearing 12 and the snap ring 211, restricting the position of the bearing 12 and preventing the bearing 12 from falling off due to long-term rotation, and further preventing the turntable 11 from falling off.

[0030] In the present utility model, by sleeving the retaining ring 22 outside the snap ring 211, the snap ring 211 is made to closely adhere to the outer ring of the bearing 12, so that an interference fit state is always maintained between the outer ring of the bearing 12 and the snap ring 211, thereby restricting the position of the bearing 12 and preventing the bearing 12 from falling off due to long-term rotation, and further preventing the turntable 11 from falling off.

[0031] Furthermore, a first clamping groove 112 that cooperates with the bearing 12 is provided on the outer side of the seat ring 111, and a first guiding surface 113 is provided on one side of the first clamping groove 112. A second clamping groove 212 that cooperates with the bearing 12 is provided on the inner side of the snap ring 211, and a second guiding surface 213 is provided on one side of the second clamping groove 212.

[0032] Specifically, the inner ring of the bearing 12 is embedded in the first clamping groove 112 of the seat ring 111, and the axial and radial directions of the inner ring of the bearing 12 are fixed by the first clamping groove 112. During the installation process, the inner ring of the bearing 12 is aligned with the seat ring 111, and the inner ring is pressed into the first clamping groove 112 through the first guiding surface 113. Similarly, through the second guiding surface 213, the snap ring 211 can be smoothly buckled onto the outer ring of the bearing 12, so that the outer ring of the bearing 12 is clamped in the second clamping groove 212.

[0033] Furthermore, a first installation groove 214 is provided on the outer side of the snap ring 211, and the retaining ring 22 is embedded in the first installation groove 214.

[0034] Specifically, in the present utility model, the snap ring 211 is limited by the retaining ring 22 to prevent the snap ring 211 from loosening during rotation. The retaining ring 22 is clamped in the first installation groove 214 to prevent the retaining ring 22 from falling off, further improving the stability of the installation and cooperation of the internal bearing 12.

[0035] Furthermore, a logo plate 13 is provided on the side of the turntable 11 away from the seat ring 111, and the logo plate 13 is clamped outside the turntable 11. The support portion 2 further includes a transparent cover 23, and the transparent cover 23 is detachably connected to the side of the mounting seat 21 close to the snap ring 211, and the transparent cover 23 is buckled outside the logo plate 13.

[0036] Specifically, the logo plate 13 is connected to the turntable 11. When the turntable 11 rotates, the logo plate 13 will rotate synchronously. The logo plate 13 is encapsulated by the transparent cover 23 to prevent the logo plate 13 from being directly exposed to the outside. As a preferred solution of the present utility model, the transparent cover 23 and the mounting seat 21 are connected by threads.

[0037] Furthermore, a second installation groove 231 is provided on the side of the transparent cover 23 connected to the mounting seat 21, and a sealing ring 24 is embedded in the second installation groove 231.

[0038] Specifically, the sealing ring 24 can improve the sealing performance between the transparent cover 23 and the mounting seat 21. On the one hand, it can prevent moisture from entering and causing rust of the components. On the other hand, it can ensure the normal display of the logo plate 13.

[0039] Furthermore, a counterweight 14 is provided on the side of the turntable 11 close to the seat ring 111, and the counterweight 14 is detachably connected to the turntable 11.

[0040] Specifically, in the above structure, the logo plate 13 is directly connected to the turntable 11, and the turntable 11 rotates under the action of the bearing 12. By adding a counterweight 14 to the turntable 11, when the wheel hub rotates, the side of the turntable 11 provided with the counterweight 14 is affected by its own gravity, always ensuring that the entire logo plate 13 is in the vertical direction, ensuring the normal display of the logo on the logo plate 13 and not rotating with the rotation of the wheel hub.

[0041] Furthermore, a plurality of buckles 215 are circumferentially provided on the side of the mounting seat 21 away from the snap ring 211, and a snap spring 25 is provided between the plurality of buckles 215.

[0042] Specifically, the installation of the entire floating cover is connected and fixed through a plurality of buckles 215 on the surface of the mounting seat 21. As a preferred solution of the present invention, the snap ring 25 is lined between the plurality of buckles 215, which can prevent the floating cover from falling off due to the bumps during the vehicle driving, and improve the stability of the installation of the entire floating cover. Embodiment 2

[0043] An automobile wheel hub includes the automobile wheel hub floating cover fastening structure described in Embodiment 1.

[0044] In summary, the present invention introduces an automobile wheel hub floating cover fastening structure and an automobile wheel hub. By adding a retaining ring 22 outside the snap ring 211 of the fixed bearing 12 and sleeving the retaining ring 22 outside the snap ring 211, the snap ring 211 is made to closely contact the outer ring of the bearing 12, so that an interference fit state is always maintained between the outer ring of the bearing 12 and the snap ring 211, thereby restricting the position of the bearing 12 and preventing the bearing 12 from falling off due to long-term rotation, which further causes the turntable 11 to fall off.
