Description

Wheel structure

The present invention relates to a wheel structure, in particular, when the rim and the hub are combined by the two-way upright screw assembly of the plurality of spoke wires, the rim is used to align the center of the wheel shaft and the force is averaged. The overall structural strength of the rim of the present invention is greatly improved and stable, and is an innovative structural designer who is not prone to deformation.

General wheels can be used in wheelchairs or bicycles. As the generations evolve, wheels are constantly improving various components to increase strength. The conventional wheel set structure is mainly formed by the outer rim, the central hub, and the plural spoke wires connected between the rim and the hub. The inner wall of the rim is perforated with plural perforations, and one end of each spoke wire It is fixedly connected to the hub, and the other end of the spoke wire is penetrated into the rim, and a fixing member is used to interlock and fix the spoke wire. However, since most of the rim is processed by aluminum extrusion, when the spoke wire is added with the fixing locking nut, the joint surface between the spoke wire locking nut and the inner wall of the rim A circular arc surface prevents the fixing parts and nuts from fully fitting with the end face of the perforated outer edge of the rim. In severe cases, the uneven force on the deflection may be caused, and the center of the wheel shaft cannot be aligned, resulting in the overall structure of the rim being unstable; In addition, please refer to the Republic of China Patent Announcement No. M442280 "Bicycle Rim Assembly Device", which includes a rim, a wheel hub and plural spokes, among which: the inner side of the rim is provided with multiple sets of connectors, and each assembly has a set Built in the inner end of the rim, and a joint end exposed on the inner side of the rim; each spoke is provided with a fixed end set on the wheel hub, and at the other end is provided with a joint end that engages with the assembly A fixed locking groove; however, the inner side of the conventional rim is provided with multiple sets of connectors It is not through the screw-lock connection, but only through the clamping connection method that the structural strength is likely to be insufficient. For example, the long-term vibration state of the wheel body may easily cause the clamping connection element to fall off or break.

In view of the above phenomenon, the creator of this case based on years of experience in production, and then created the use of alignment to the center of the wheel shaft and average force, so that the overall structural strength of the rim of the present invention is greatly improved and the structure is stable, and it is not easy to deform. The wheel has a structure.

That is, the main purpose of the present invention is to provide a wheel structure; the problem it intends to solve is that most of the conventional wheel rims are manufactured by aluminum extrusion when they are processed. When the spoke wire is added After the fixing part locks the nut, the joint surface between the spoke wire lock nut and the inner wall of the rim is a circular arc surface, which causes the fixing part and the nut to be unable to completely fit the end surface of the perforated outer edge of the rim. In severe cases, the deflection will be unevenly applied and the center of the wheel cannot be aligned, resulting in the problem of instability in the overall structure of the rim. The technical features to solve the problem include a rim with an inner peripheral surface ring. A plurality of penetrating parts are evenly distributed in the shape of the rim, and a hub is provided at the center of the inner part of the rim. The hub is provided with a corresponding through hole on both sides of the hub corresponding to each penetrating part of the rim. The penetrating part and the through hole are respectively It is assembled by relatively staggered combination of a plurality of spoke wires, wherein the spoke wires respectively have a first connecting thread segment and a second connecting thread segment. The first connecting thread segment is inserted through the through holes on both sides of the hub. It is combined by a screw assembly, and the second connecting screw segment is inserted into each through part of the rim, and then relatively screwed to the rim by a first nut member and a second nut member The second connecting screw segment makes the first nut member and the second nut member pair-locked at the inner and outer end surfaces of the peripheral edge of the penetration portion; a plurality of forcing end surfaces are respectively formed on the inner peripheral surface of the rim and opposite to each other The relative vertical connection position of each spoke wire, that is, a unit of spoke wire is vertically opposed to the pressing end face of a unit, wherein the relative angle between the center axis of each spoke wire and the corresponding pressing end face It is a 90-degree vertical vertical surface, and an angle turning area is formed between each of the forcing end faces. By the angle turning area, each of the forcing end faces forms an inclined surface facing inward and outward, and in sequence Arranged so that the first nut member and the second nut member are locked to the second connecting screw segment of the spoke wire and fastened to the rim, the first nut member and the second nut The contact end surface of the cap relative to the rim can more completely contact the corresponding urging end surface; by this innovative and unique design, the present invention uses the central axis of each spoke wire and the rim The relative arrangement angle of the corresponding force end face and the hub is a vertical vertical surface, and through the angle turning area, each of the force end faces forms an inward and outward inclined surface, and they are arranged in order to make the When the first nut member and the second nut member are locked to the second connecting screw segment of the spoke wire and fastened to the rim, the first nut member and the second nut member are opposite to the The contact end surface of the rim can completely contact the corresponding force end surface, so that when the rim and the hub are combined by the two-way upright screw assembly of the plural spoke wires, the use of the rim is Aligning with the center of the wheel shaft and then applying the force evenly, the overall structural strength of the wheel set of the present invention is greatly improved and the structure is stable, and it is difficult to deform.
