Description

Bicycle hub structure

This creation is related to a bicycle hub structure, especially a multi-piece hub structure with a bonding glue between the middle tube and the face plate to provide a stable and lightweight hub structure.

At the junction of the front fork or rear fork and the wheel of a bicycle, a hub is mainly used. The hub provides the function of a fixed shaft and can be combined with the spokes of the wheel so that the wheel can rotate relative to the hub to provide the vehicle forward Or the driving function of backwards.

The general hub structure has a shaft tube, two faceplates and two bearing parts. The two faceplates are respectively assembled at the two ends of the shaft tube, and the two bearing parts are respectively assembled between the two facets and the shaft tube. And the two faceplates are provided with multiple perforations for combining with the spokes of the wheels.

Common hub structures are mostly one-piece or multi-piece, forming the structural design of each shaft tube and faceplate. The one-piece hub structure has better strength, but the one-piece hub requires multiple additional processing. Program processing, resulting in increased manufacturing costs.

By the way, the conventional multi-piece hub structure, such as the "Human Hub Improved Structure (2)" disclosed in the domestic new patent No. 084204738, mainly includes a hub body with a double open end and a ring of the hub body. There are bumps on the circumference and spaced apart, and a shoulder is provided at both ends of the bump; two drive systems are used to sleeve the two ends of the hub body, and the circumference of the drive body is provided with a web The inner ring is provided with a concave part and a convex part; two sets of caps are formed with a threaded part at one end for screwing into the hub body.

Another multi-piece hub structure, such as the "bicycle hub" disclosed in the domestic new patent No. 095221755, includes: a shaft tube, which is a hollow tube body and includes a plurality of side surfaces to form a multi-faceted tube Body, each end of the shaft tube has a polygonal cross section perpendicular to its axis; two faceplate parts are separately provided at both ends of the shaft tube, each of the faceplate parts includes a joint part that is joined to the corresponding The shaft tube end has a coupling hole whose shape corresponds to the polygonal cross section of the coupling end; and a face plate connected to the coupling portion and has a plurality of web holes.

In the above-mentioned structure, the former structure is provided with convex blocks on the circumference of the hub body, and the inner rings of the two driving blocks are provided with concave and convex parts, so that the two driving blocks are respectively sleeved on the hub body Two ends; the latter structure is that the shaft tube system is formed with multiple side surfaces, and the two faceplate parts correspond to the shape of the shaft tube for setting at both ends of the shaft tube.

However, the concave and convex parts of the inner ring of the two driving blocks of the former structure are not easy to process and shape, and the accuracy of the forming is poor, which affects the tightening ability of the two drivers and the hub body; the latter has the structure of the aforementioned two known pieces The type of hub structure has the advantages of easier assembly and lower cost, but its tightening ability is low, and it is easy to loosen. Therefore, the creator of this case, based on the concept of multi-piece combination, further provides a joint part with plural side surfaces formed between the two ends of the middle tube and the two faceplates for mutual penetration, matching the extension seat and the faceplate of the faceplate. The groove design has better covering properties, strong tightening force, easy forming, low cost, and its multi-piece type is easy to assemble, which can effectively improve convenience and practicality.

This creation provides a bicycle hub structure, which contains: a middle tube and two Each end has a first coupling part; two wheel discs are respectively assembled on the two ends of the middle tube, and a plurality of assembly connection holes are provided around the wheel disc for assembly and combination with the spokes. The axis of the wheel disc There is a set of connecting parts and a second connecting part. The outer circumference of the roulette corresponds to the shape of the first connecting part for mutual insertion; a glued part is provided for each of the first connecting parts of the middle tube Part, and the roulette knows between each of the second joint parts, so that the first joint part and the second joint part are tightly glued, and multiple sets are connected to form a single-piece hub set to improve the design kinetic energy and flexible production to solve the current problem. Those who have manufacturing process problems, reduce inventory and time costs, truly have excellent innovation and convenience and practicability, and improve the convenience of production, and the overall components are simple and the production time is shortened, so that they can achieve excellent practicability and convenience; , The groove design can be used to make the gluing tighter, and the gold mold can be quickly assembled to facilitate the production of hub bodies of different specifications and achieve the convenience of quick assembly.

The first figure is a three-dimensional external view of a preferred embodiment of the creation.

The second figure is a three-dimensional exploded view of a preferred embodiment of the creation.

The third figure is a combined cross-sectional view of a preferred embodiment of the creation.

The fourth figure is a partial cross-sectional view of the creation of a preferred embodiment.

First of all, please refer to the first to fourth pictures. The bicycle hub structure provided by this creation includes: a middle tube (10) and two wheels (20).

The middle tube (10) is a hollow tube body, and its two ends respectively have a first joining portion (11), wherein the first joining portion (11) is tied to the inner circumference of the middle pipe (10), and the The middle tube (10) can be made of carbon fiber material, aluminum material, or other lightweight materials.
