[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides a high-strength hub mounting sleeve for motorcycle swingarm components. Please refer to [link / reference]. Figures 1-5 The device includes a hub spindle 2, a sleeve 3 fitted on the hub spindle 2, a reinforcing sleeve 10 fitted on the sleeve 3, the reinforcing sleeve 10 is used to reinforce the strength of the sleeve 3, a bearing is installed between the sleeve 3 and the hub spindle 2, the two ends of the sleeve 3 have hub discs, and the hub discs and the hub spindle 2 are together fitted with an installation sleeve structure;

[0026] The mounting sleeve structure has a limiting block 1113, and the hub spindle 2 has an annular groove 21, the end of the hub spindle 2 is inserted into the annular groove 21.

[0027] The sleeve 3 has a left hub plate 4 and a right hub plate 6 at its two ends, respectively. A sprocket 8 is fixedly installed on the right hub plate 6. A left bearing 5 is installed between the left hub plate 4 and the hub spindle 2. A right bearing 7 is installed between the right hub plate 6 and the hub spindle 2.

[0028] The mounting sleeve structure includes a first collar 9, and the first collar 9 is bolted to a second collar 11;

[0029] The inner wall of the first ring 9 is provided with an internal thread that matches the thread on the outer wall of the left hub 4 and the right hub 6; the left hub 4 and the right hub 6 are both threadedly connected to the first ring 9.

[0030] The second ring 11 is composed of two semicircular rings 111. The ends of the two semicircular rings 111 are each welded with a first fixing block 1111. The two semicircular rings 111 are fixed together by bolts. The limiting block 1113 is welded to the inner wall of the semicircular ring 111. Under normal circumstances, the limiting block 1113 does not contact the inner wall of the ring groove 21, so it will not affect the normal operation of the sleeve 3 and the mounting sleeve structure.

[0031] A second fixing block 1112 is welded onto the semi-circular ring 111. The second fixing block 1112 and the first collar 9 are provided with internal threaded holes at corresponding positions. The second fixing block 1112 and the first collar 9 are fixed together by bolts.

[0032] In practical use, the two first rings 9 are respectively fitted from both ends of the hub spindle 2, and then the two first rings 9 are threaded to the left hub disc 4 and the right hub disc 6 respectively. The two semi-circular rings 111 are fitted from the top and bottom of the hub spindle 2, and then the two semi-circular rings 111 are fixed together with bolts. Then the semi-circular rings 111 are fixed to the first rings 9 with bolts. At this time, the end of the limiting block 1113 is inserted into the ring groove 21 of the hub spindle 2.

[0033] Under normal circumstances, the limiting block 1113 does not contact the inner wall of the ring groove 21, thus not affecting the normal operation of the sleeve 3, the first ring 9, and the second ring 11. When the left bearing 5 or the right bearing 7 malfunctions, the left bearing 5 or the right bearing 7 will not overflow from the inner cavity of the left hub plate 4 and the right hub plate 6 due to the obstruction of the second ring 11 and the first ring 9, thus avoiding the occurrence of danger.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
