Rim with high-strength spoke weave

Abstract

The invention provides a rim with a high-strength spoke weaving mode. The rim comprises a hub, a wheel frame and at least three first spoke sets; the hub is equipped with a first virtual circle; the wheel frame is annularly arranged at the outside of the hub; the first spoke sets are arranged between the hub and the wheel frame, each comprising a first spoke and two second spokes; the first spoke and the two second spokes form an unique intersection point; an included angle ranging from 30 to 80 degrees is formed between the first spoke and the second spokes; the second spokes are positioned at two sides of the first spoke; a virtual extending line of the first spoke passes through the center of the first virtual circle; the second spokes are tangent to the first virtual circle. According to the rim, the first spoke and the second spokes are intersected, so that the first spoke can be effectively avoided being deformed due to bearing excessive pressure; particularly the second spokes can effectively share the tension force on the first spoke when the included angle ranges from 30 to 80 degrees.

Description

technical field [0001] The invention mainly discloses a wheel rim, especially a wheel rim with a high-strength weaving method, which is braided with three spokes as a group and intersecting at one point. Background technique [0002] With the improvement of people's quality of life, the requirements for the quality of leisure activities are getting higher and higher. Riding a bicycle is a very common way of leisure for modern people. It can not only achieve exercise effects and maintain health, but also can be used as a means of transportation for sightseeing. Very convenient. [0003] In order to make the bicycle take into account both performance and safety, the rim of the bicycle plays a very important role, and the weaving method of the spokes in the rim is the most critical. The most common weaving methods of the spokes are straight-pull and half-tangential. Pulled spokes pass through the center of the rim, while half-tangential spokes do the opposite. When the spokes...

Problems solved by technology

[0004] However, when the spokes of the rim are woven with straight-pull spokes, the rim is easily deformed by running over potholes or being hit

When the spokes of the rim are woven with half-tangential spokes, the efficiency of the spokes to transmit force is poor, and it will increase the wind resistance of the rim

[0005] For this reason, knowledgeable people in the technical field have developed a kind of wheel rim that uses two kinds of different weave way spokes at the same time, but this type of wheel rim still can't improve the above-mentioned problem, and the straight-pull type spoke that uses is many, Then the compressive strength is poor, and it is not impact-resistant, and when there are many half-tangential spokes, the efficiency of power transmission is poor, and the manufacturer must produce a variety of different rims according to various riding environments. Riders need to evaluate their own riding environment in advance and choose different tires, which is quite troublesome
