[0039] The side ring 2 is in the shape of a circular ring as a whole, and the material of the side ring 2 can also be aluminum alloy, magnesium alloy, etc. The side ring 2 can be located at the rear side of the wheel hub 1, and an annular groove 21 can be provided in the side ring 2, and the annular groove 21 can be a step groove, and the annular groove 21 can be extended along the circumference of the side ring 2 to be closed into a circle. During assembly, the annular portion 11 can be embedded in the annular groove 21 as a whole, and the annular portion 11 and the annular groove 21 are used to form the above-mentioned bonding surface with the surfaces that fit each other.

[0040] like Figure 2 and Figure 3 As shown, the sealing ring groove 113 can be only provided on the joint surface of the annular portion 11, the sealing ring groove 113 is annular as a whole, and the sealing ring groove 113 can be extended along the circumference of the annular portion 11 to be closed into a circle. In some other embodiments, the sealing ring groove 113 can also be provided on the side ring 2, specifically, it can be located on the inner circumference of the side ring 2. In this case, the sealing ring groove 113 is also annular and can be extended along the circumference of the side ring 2 to be closed into a circle.

[0041] The fastener 3 passes through the edge ring 2 and is connected to the annular portion 11. For example, the fastener 3 may be a bolt, a screw, etc., and may be a M6 high-strength screw. Figure 3 As shown, the fastener 3 can pass through the side ring 2 and be threadedly connected to the annular portion 11. The fastener 3 can realize the detachable assembly of the side ring 2 and the wheel hub 1.

[0042] The sealing ring 4 is embedded in the sealing ring groove 113 and is sealed between the joint surface of the annular portion 11 and the annular groove 21. Figure 1 and Figure 3 As shown, the sealing ring 4 can be a rubber ring, and the sealing ring 4 is annular. When assembled, the sealing ring 4 can be embedded in the sealing ring groove 113 and can be exposed from the sealing ring groove 113. When the side ring 2 is fixed to the wheel hub 1 by the fastener 3, the sealing ring 4 can be clamped between the side ring 2 and the wheel hub 1, and the sealing surface of the side ring 2 and the wheel hub 1 can be sealed by the extrusion deformation of the sealing ring 4.

[0043] The rim of the embodiment of the utility model can be assembled with the tire on the outer peripheral side of the rim. When the tire needs to be repaired and maintained, the side ring 2 can be removed from the wheel hub 1, and then the tire can be directly pushed out from the wheel hub 1, thereby facilitating the installation and removal of the tire and improving the convenience of tire repair and maintenance.

[0044] Secondly, the cooperation between the annular portion 11 and the annular groove 21 can, on the one hand, enhance the limiting cooperation effect between the hub 1 and the side ring 2, and on the other hand, further improve the overall air tightness of the hub 1 and the side ring 2 after assembly, and also ensure the overall assembly structure strength.

[0045] In some embodiments, the side ring 2 includes a first ring portion 22 and a second ring portion 23.

The angle space formed by the first ring portion 22 and the second ring portion 23 constitutes an annular groove 21, and the annular groove 21 is located on the inner side of the second ring portion 23.

[0046] For example, Figure 3 As shown, the first ring portion 22 can be disc-shaped as a whole, and the second ring portion 23 can be cylindrical as a whole. The second ring portion 23 can be integrally formed on the left side of the first ring portion 22, and the cross section of the overall structure formed by the first ring portion 22 and the second ring portion 23 can be substantially "T"-shaped. Therefore, in the radial direction of the edge ring 2, the first ring portion 22 and the second ring portion 23 can limit two angle spaces, and the second ring portion 23 is located between the two angle spaces, wherein the angle space located inside the second ring portion 23 is the above-mentioned annular groove 21.

[0047] When assembling, Figure 3 As shown, the annular portion 11 is directly plugged into the angle space limited by the first annular portion 22 and the second annular portion 23 , and the annular portion 11 is simultaneously stop-fitted with the first annular portion 22 and the second annular portion 23 .

[0048] In some embodiments, the mating surface of the annular portion 11 includes an end surface 111 facing the end of the hub 1 and a peripheral surface 112 facing the outer peripheral side of the hub 1, the end surface 111 is in contact with the first ring portion 22, the peripheral surface 112 is in contact with the second ring portion 23, and a sealing ring groove 113 is provided on the peripheral surface 112.

[0049] For example, Figure 3 As shown, the end surface 111 may be the right end surface of the annular portion 11, the peripheral surface 112 may be the outer peripheral surface of the annular portion 11, and both the end surface 111 and the peripheral surface 112 may be annular. When the side ring 2 and the wheel hub 1 are assembled, the end surface 111 may be in contact with the left side surface of part of the first ring portion 22, and the peripheral surface 112 may be in contact with the inner peripheral wall of the second ring portion 23.
