Description

Composite hub spokes for applicable wheels

This creation is related to a technical field related to transportation equipment, especially the spokes of bicycle or motorcycle wheel hubs are set as a composite structure to improve strength.

According to a bicycle or a locomotive, the wheel will include a hub, a wheel frame and tires mounted on the periphery of the wheel frame. A number of spokes are connected between the wheel hub and the wheel frame. The two ends of the spokes are generally set as a threaded end and a hook head. In the early days, the spokes were all made of metal. As bicycles increasingly pursued the trend of lightweight, the spokes of bicycles gradually changed to composite materials such as carbon fiber. Although carbon fiber is lightweight and has high tensile strength, it is quite difficult to process the threaded end from composite materials. Therefore, if you refer to the patent application for the invention of "Bicycle Spoke Fixing Structure" No. 097105202 of the previous case 1, the above reasons will be discussed. Improvement is made, the spokes are mainly made of composite material, the first end extends through the wheel frame and forms an enlarged end, and the second end extends through an adjustment member and the adjustment hole of the hub to form an enlarged end, so refer to the previous case A main body of composite material, plus an adjustment piece forming a hook head at both ends, and an adjustment piece forming a threaded end, can be combined with the hub and the wheel frame, but the adjustment piece of carbon fiber composite material and metal is only in the The sleeve combination of the two ends of the spokes has a small contact area and poor bonding force. In the case of repeated vibrations on the riding road, It is easy to cause the main body of the composite material to peel off from the adjusting member, and even the spoke loses its connection with the adjusting member, resulting in a dangerous situation where the spoke is detached.

In addition, refer to the previous case No. 2, which is the invention patent of the "spoke structure of the wheel" with the certificate number I375627. Its structure includes a main body made of carbon fiber and two connecting parts, at least one of which has a head at one end of the connecting part , its inner end is connected to a diameter-reducing section, and a bonding layer is arranged on the reducing-diameter section, and the bonding layer is made of the same material as the main body; one end of the main body wraps the head of the connector and the The bonding layer is closely connected with the bonding layer, so that the bonding strength between the connecting piece and the main body can be greatly improved.

The main body of the above-mentioned reference to the previous case 2 is made of carbon fiber composite material, and a connecting piece is connected to each of the two ends of the corresponding wheel frame and hub. Around joints; although referring to the previous case 2, the main body is made of carbon fiber composite material, which improves the lightweight characteristics, but the connection between the connector and the main body requires a complicated manufacturing process, because the connector needs to be pre-processed into a flat or a bonded layer with a predetermined shape The bonding layer is then covered with carbon fiber composite material, so that it can be combined with the main carbon fiber composite material, so the manufacturing cost is high and the manufacturing process is complicated.

In view of the aforementioned problems, the author researched and developed it. The main purpose of this creation is to provide a composite hub spoke suitable for wheels. Composite materials such as carbon fiber are coated on the outside of the main pole, which can provide good strength, light weight, and greatly reduce The process and cost of bonding additional components.

The reason is that according to the invention, a composite hub spoke suitable for wheels, a spoke system includes a main rod and a cladding material, wherein: the main rod is integrated with metal material, and one end of the main rod is set as a threaded end , the other end is a hook head, and the area between the threaded end and the hook head is set at least one curved waist section, the outer diameter of the main body rod decreases gradually toward the curved waist section, and the center of the curved waist section The smaller outer diameter is defined as a central area; the cladding material is a composite material, which is used to cover and fix the outer surface of the main body rod, and it is from the place adjacent to the thread end to the main body of the hook head The outer surface of the rod is tightly covered and fixed, and the covering range of the covering material includes the curved waist section and the peripheral side of the hook head, and the covering material is thicker in the central area.

Therefore, this creation provides the following effects:

1. The spokes of this creation are composed of an integrated main rod covered with cladding material on the outside, so the two ends of the main rod are integrally formed with a hook head and a threaded end, so the main rod, hook head, and threaded end are One piece, different from the previous components that are additionally connected to the hook head or threaded end, so the integrated spoke is strong enough, and there is no worry that the hook head and threaded end will fall off.

2. In the spokes of this creation, the one-piece main body rod forms at least one curved waist section at the center, so that the outer diameter of the main body rod in the overall axial range presents a difference in size, so the overall outer diameter of the main body rod is different. Due to the restriction formed by the change of the outer diameter of the main body rod, the thickness of the main body rod covered by the cladding material is different, which effectively and significantly increases the occlusal contact area between the main rod and the cladding material, making it extremely difficult for the cladding material to slip from the main rod Departure It is separated, and the combination is good, and the main rod is combined with the cladding material, which improves the tensile strength, reinforces the overall strength, and makes the spokes have the advantage of being lightweight.

3. The spokes are also covered with cladding material at the end of the hook head, which moderately enhances the bonding strength of the hooking contour of the hook head.
