Description

Combination of bicycle spoke wire and flower hub

The invention mainly discloses a combination of a bicycle spoke wire and a flower hub, in particular a combination of a spoke wire and a flower hub for preventing the spoke wire from directly pressing against the flower hub.

Referring to the Patent No. M246192 of the Republic of China Patent No. M246192, the aperture shape of the spoke wire hole is in the shape of a flying saucer. The circumference of the aperture of the spiro wire hole has a radius of different lengths, which is rounded. The aperture is formed by overlapping the aperture and the aperture, which can simultaneously allow the circular spoke and the flat spoke to pass through. The spokes are arranged at one end of the spoke hole of the flower hub, and the other end is set on the rim and the flower is arranged. The hub and the rim are combined, and on the one hand, the human body can step on the pedal to apply the rotational force of the flower hub, and the rotation of the spoke can drive the rim to roll, so that the bicycle can advance; The spokes are used to form a support between the hub and the rim to withstand the weight of the frame, components and the human body. However, the existing wire spokes are limited by the high density of the material itself, so that the overall weight is greatly increased. In addition to causing the rider to make the ride more laborious, the rust corrosion of the wire also increases the maintenance cost.

In order to improve the shortcomings of the conventional wire spokes, the industry has developed a spoke structure with a composite material as a spoke. Referring to the Patent No. M325932 of the Republic of China Patent No. M325932, which comprises a plate body and a connecting group, the plate system is a long plate of a composite material, and the two ends of the plate body are respectively set to one. a first end edge and a second end edge; the connection group is set The first and second connecting members of the first and second connecting members are respectively in a non-continuous state and are in a non-continuous state. A fixing portion is provided in an enlarged state, and each of the first fixing portions is embedded in each of the first and second end edges. With the above-mentioned members, the design of each of the fixing portions to have a larger outer edge than the rod body ensures that the connection group and the plate body are firmly snap-fitted, and the tension of the joint portion is effectively enhanced.

However, the existing composite spoke wire technology still has a lack of use, the spoke wire directly penetrates the spoke wire hole, and the head of the spoke wire blocks the spoke hole of the flower hub, when the rim rotates, the spoke wire Will pull the force, the head of the spokes will be pressed around the spoke hole, but the splice head will be pressed around the spoke hole to cause stress concentration, which may cause the flower hub to crack, especially It is a carbon fiber material hub, and it is easy to crack because the stress is concentrated on the filament hole. Furthermore, only one end of each spoke is bonded to the rim, so that all the forces acting on the spoke are transmitted from one end of the rim to the spoke and the hub, long term, not only the length of each spoke There will be differences, and the part of the rim combined with the spokes will also be concentrated and damaged, which will affect the smoothness of the rim operation. For the above problems, there is a need for improvement.

Accordingly, the present invention is intended to obviate or at least alleviate the problems encountered in the prior art.

The technical problem to be solved by the present invention is to provide a combination of a bicycle spoke and a flower hub in view of the above-mentioned shortcomings existing in the prior art.

The main object of the present invention is that the spoke has an assembly portion and at least two joint portions, and the assembly portion is integrally formed on the seat plate to prevent the spokes and the seat plate from being loosened due to vibration, and The one-piece design allows the stress transmitted from the spokes to the seat plate to be dispersed to the seat pan. The joint effectively disperses the stress acting on the rim, so the limit of the rim and the spokes is not damaged by stress concentration. The service life of the rim.

A secondary object of the present invention is to form a limiting surface at the end of the protruding portion, and the limiting surface forms a limit against the bottom surface of the mounting portion to prevent the seat disk from moving toward the second end of the flower hub.

Another object of the present invention is that the portion of the spoke wire that is adjacent to the assembly portion is passed through the notch of the restriction portion, and the spoke wire is restrained by the notch without rotating relative to the hub.

Still another object of the present invention is that the distance between the spoke link portion and the assembly portion is a fixed value, and the distance between the rim and the hub can be defined to increase the smoothness of the rim rotation when riding.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.
