Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts, in particular to a motorcycle wheel hub adjusting bushing. Background Art

[0002] A bushing is a cylindrical mechanical part sleeved on a rotating shaft. It can be a component of a sliding bearing or an adjusting part for adjusting the distance on the shaft. Generally, the bushing has a clearance fit with the shaft. A motorcycle adjusting bushing is a protective and adjusting part for a motorcycle axle, used to adjust the wheel hub so that the wheel hub remains in the center of the shock absorption. The existing motorcycle bushings are sleeved on the central shaft of the wheel hub in a bulk manner, and the technical effect of adjusting the distance is achieved by stacking, so as to adjust the wheel hub to always remain in the center of the shock absorption.

[0003] However, the bulk bushings are easy to scatter when disassembled or installed. When adjusting, multiple people are required to cooperate to insert shims to adjust the center, and the installation and disassembly operations are inconvenient, time-consuming and laborious.

[0004] Therefore, in view of the above-described technical problems, the applicant has designed a motorcycle wheel hub adjusting bushing that is convenient for disassembly and installation in combination with the existing bushings. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the above-mentioned technical defects, and provide a motorcycle wheel hub adjusting bushing. The purpose is to achieve the technical effect of quickly adjusting the wheel hub to maintain the shock absorption center by the adjusting bushing sleeved on the central shaft of the wheel hub, and objectively solve the technical problem that the existing bulk bushings are easy to scatter and difficult to disassemble and install.

[0006] To solve the above technical problems, the technical solution provided by the utility model is: a motorcycle wheel hub adjusting bushing, including a large bushing and a small bushing arranged coaxially. One end of the large bushing is fixedly connected to the small bushing. The large bushing and the small bushing have the same inner diameter, and the outer diameter of the large bushing is greater than the outer diameter of the small bushing.

[0007] Further, the large bushing and the small bushing are integrally arranged, and the large bushing and the small bushing are sleeved on the central shaft of the wheel hub together.

[0008] The advantages of the utility model compared with the prior art are as follows: the utility model is provided with a large bushing and a small bushing arranged coaxially, sleeved on the central shaft of the wheel hub, with one end in contact connection with the wheel hub and the other end in contact connection with the shock absorber frame, so that the position of the wheel hub can be quickly adjusted to be centered. The structure design of the utility model is simple, greatly simplifies the installation and disassembly process, is convenient and fast for installation and disassembly, saves time and effort, and has strong practicability.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0013] In the description of the embodiments of the present utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this utility model is usually placed when in use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0014] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0017] Embodiment 1:

[0018] With reference to the attached drawings, a motorcycle wheel hub adjusting shaft sleeve includes 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, and the outer diameter of the large shaft sleeve 1 is greater than the outer diameter of the small shaft sleeve 2.

[0019] In a preferred embodiment of this example, the large shaft sleeve 1 and the small shaft sleeve 2 are integrally formed and are sleeved together on the hub central axis.

[0020] During specific implementation, the large shaft sleeve is in contact connection with the shock absorber frame, and the small shaft sleeve is in contact connection with the wheel hub. The lengths of the large shaft sleeve and the small shaft sleeve are appropriate, which can quickly center the wheel hub. There is no need for multiple people to operate by adding loose shaft sleeves. One person can complete the installation and disassembly alone. The adjustment is fast and convenient, and it has strong practicability.

[0021] In a preferred embodiment of this example, the large shaft sleeve 1 and the small shaft sleeve 2 are made of 7075 aviation aluminum material. This material is light in weight, not easily corroded, and has a long service life.

[0022] Through the design of one end of the shaft sleeve being large and the other end being small, the small end is designed according to the bearing size, which can reduce the friction force and make the bearing run more smoothly. The large end has a larger diameter and is more firmly and durably stuck on the central axis, with better fixity.

[0023] The above describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
