Motorcycle hub adjustment sleeve

Abstract

To provide a hub adjusting sleeve for a motorcycle which has a simple structure, greatly simplifies the work of mounting and dismounting, and can be operated quickly and easily. [Solution] A motorcycle hub adjustment sleeve includes a coaxially arranged large sleeve 1 and small sleeve 2, one end of which is fixedly connected to the small sleeve, the large sleeve and small sleeve having the same inner diameter and a larger outer diameter than the small sleeve. The coaxially arranged large sleeve / small sleeve is attached to the hub central shaft, and one end abuts against the suspension frame 4 and the other end abuts against the hub 3, allowing the hub position to be quickly and reliably adjusted to the center.

Description

[Technical Field]

[0001] This utility model relates to the technical field of motorcycle parts, and in particular to a hub adjustment sleeve for motorcycles. [Background technology]

[0002] A sleeve is a cylindrical part that fits onto a rotating shaft and is used as a component of a plain bearing or as a part to adjust the clearance on the shaft. The sleeve usually has a loose fit with the shaft. Adjustable sleeves for motorcycles are designed to protect the axle and adjust the position of the hub, keeping it centered in the suspension. A conventional technique is to attach each sleeve individually to the hub central shaft and stack the required number of sleeves to adjust the clearance and keep the hub always centered in the suspension. However, the individually attached sleeves are prone to becoming dislodged when being attached or removed, and multiple people are required to adjust them by adding spacers, which makes the work process complicated and takes a lot of time and effort. Therefore, in order to solve the above problems, the applicant has devised a new motorcycle hub adjustment sleeve that is easy to install and remove. Summary of the Invention

[0003] The purpose of this utility model is to overcome the drawbacks of the prior art and provide a motorcycle hub adjustment sleeve that can be attached to the hub central shaft to quickly adjust the hub position and keep it centered on the suspension. Furthermore, it objectively solves the problems of the prior art, such as the scattering of individual sleeves and the complicated installation and removal process.

[0004] The invention is configured as follows: A motorcycle hub adjustment sleeve includes a large sleeve and a small sleeve arranged coaxially, one end of the large sleeve is fixedly connected to the small sleeve, the large sleeve and the small sleeve have the same inner diameter, and the large sleeve has a larger outer diameter than the small sleeve. Furthermore, the large sleeve and small sleeve are integrally molded and attached to the hub central shaft.

[0005] This utility model has the following advantages over the prior art: This utility model uses a coaxially arranged large sleeve / small sleeve attached to the hub central shaft, with one end abutting the suspension frame and the other end abutting the hub, allowing for quick and reliable central adjustment of the hub position. This utility model has a simple structure, greatly simplifies installation and removal, and is quick and easy to operate, saving labor and providing high practicality. [Brief explanation of the drawings]

[0006] [Figure 1] FIG. 1 is a schematic diagram of a motorcycle hub adjustment sleeve according to the present invention. [Figure 2] FIG. 2 is a diagram showing the mounted state of the motorcycle hub adjustment sleeve according to the present utility model. DETAILED DESCRIPTION OF THE INVENTION

[0007] Example 1: As shown in the drawings, this is a motorcycle hub adjustment sleeve comprising a large sleeve 1 and a small sleeve 2 arranged coaxially, one end of the large sleeve 1 is fixedly connected to the small sleeve 2, the large sleeve 1 and the small sleeve 2 have the same inner diameter, and the outer diameter of the large sleeve 1 is larger than the outer diameter of the small sleeve 2. In a preferred embodiment, the large sleeve 1 and the small sleeve 2 are integrally molded and are mounted integrally on the hub central shaft. Specifically, by abutting the large sleeve against the suspension frame and the small sleeve against the hub and setting the lengths of both sleeves appropriately, the hub position can be quickly adjusted to the center with a single structure, without the need to prepare and attach multiple individual sleeves.This means that installation and removal work can be carried out by one person more reliably and in a shorter time than before, greatly improving practicality. In a more preferred embodiment, the large sleeve 1 and the small sleeve 2 are made of 7075 aeronautical grade aluminum alloy, which is lightweight, has excellent corrosion resistance, and can ensure a long life.

[0008] Although the present utility model and its embodiments have been described above, this description is not limiting, and the drawings are merely examples of the present utility model, and actual applications are not limited thereto. In other words, any structural aspects and embodiments similar to the technical means designed by a person skilled in the art based on the suggestions and without departing from the spirit of the invention of the present utility model shall all fall within the scope of protection of the present utility model.
