Description

Technical area

[0001] The utility model relates to the technical field of motorcycle parts, specifically it relates to an adjusting shaft sleeve for motorcycle wheel hubs. Background technology

[0002] The shaft sleeve is a cylindrical mechanical part that is mounted on the rotating shaft. It can be part of the plain bearing or an adjustment component for adjusting the clearance on the shaft. The sleeve is generally mounted on the shaft with a clearance fit. The motorcycle adjustment sleeve is a protective and adjustment component for the motorcycle axle. It is used to adjust the wheel hub so that the wheel hub remains in the center position of the shock absorber. The existing motorcycle axle sleeve is sleeved solidly on the central shaft of the wheel hub, and the technical effect of adjusting the clearance is achieved through superposition, so that the adjustment wheel hub is always held in the position of the shock absorption center.

[0003] However, the loose shaft sleeves are easily scattered all over the floor during disassembly or installation, and multiple people are required to coordinate the center during adjustment and adding gaskets, making the installation and disassembly processes cumbersome, time-consuming and labor-intensive.

[0004] Therefore, in view of the technical problems described above, the applicant has developed an adjusting shaft sleeve for motorcycle wheel hubs which can be easily disassembled and assembled in combination with existing sleeves. Contents of the utility model

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned technology and provide an adjusting shaft sleeve for motorcycle wheel hubs. The purpose is to achieve the technical effect of quickly adjusting the wheel hub to maintain the shock absorption center through a sleeve mounted on the center axis of the wheel hub, and objectively solve the technical problem that existing mass sleeves are prone to falling apart and difficult to disassemble and install.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the utility model is to provide an adjusting shaft sleeve for a motorcycle wheel hub, comprising a large shaft sleeve and a small shaft sleeve arranged coaxially. One end of the large shaft sleeve is fixedly connected to the small shaft sleeve. The inner diameters of the large shaft sleeve and the small shaft sleeve are the same. The outer diameter of the large shaft sleeve is larger than the outer diameter of the small shaft sleeve.

[0007] In addition, the large shaft sleeve and the small shaft sleeve are integrated and fixed together on the center axis of the wheel hub.

[0008] Compared with the prior art, the utility model has the following advantages: The utility model discloses a large shaft sleeve and a small shaft sleeve arranged coaxially and mounted on the center axis of the wheel hub. One end is connected to the wheel hub, and the other end is connected to the shock absorber frame, allowing the position of the wheel hub to be quickly adjusted to keep it centered. The utility model discloses a simple structural design, greatly simplifies the installation and disassembly process, and installation and disassembly are convenient and quick, saving time and effort, and offering strong practicality. Description with drawings Fig. is a schematic structural diagram of the utility model motorcycle wheel hub adjusting shaft sleeve. Fig.is a schematic structural diagram of the assembly of the adjusting shaft sleeve for motorcycle wheel hubs according to the utility model.

[0009] As shown in the figure: 1. Large shaft sleeve, 2. Small shaft sleeve, 3. Wheel hub, 4. Shock absorber frame. The specific embodimentEmbodiment 1:

[0010] In conjunction with the attached drawings, an adjusting shaft sleeve for motorcycle wheel hubs comprises a large shaft sleeve 1 and a small shaft sleeve 2 arranged coaxially. One end of the large shaft sleeve 1 is fixedly connected to the small shaft sleeve 2. The inner diameters of the large shaft sleeve 1 and the small shaft sleeve 2 are the same. The outer diameter of the large shaft sleeve 1 is larger than the outer diameter of the small shaft sleeve 2.

[0011] A preferred implementation of this embodiment is that the large shaft sleeve 1 and the small shaft sleeve 2 are integrated and the large shaft sleeve 1 and the small shaft sleeve 2 are fixed together on the center axis of the wheel hub.

[0012] In the actual implementation, the large shaft sleeve rests against the shock absorber frame, and the small shaft sleeve rests against the wheel hub. The lengths of the large shaft sleeve and the small shaft sleeve are moderate, allowing the wheel hub to be quickly adjusted to the center. Multiple people are not required to operate the shaft sleeves repeatedly. Installation and removal can be performed by a single person. The adjustment is quick and convenient, making it extremely practical.

[0013] A preferred implementation of this embodiment is for the large shaft sleeve 1 and the small shaft sleeve 2 to be made of 7075 aircraft-grade aluminum. This material is lightweight, resistant to corrosion, and has a long service life.

[0014] The utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited to it. In short, if an average person skilled in the art can be inspired by it and, without deviating from the creative purpose of the utility model, design a structural method and embodiment similar to the technical solution without creativity, they all fall under the protection of the utility model.
