Adjustable carbon fiber wheel rim combined structure

Abstract

The invention belongs to the field of vehicle wheel accessories and particularly discloses an adjustable carbon fiber wheel rim combined structure which comprises a wheel frame, spokes and a hub. The adjustable carbon fiber wheel rim combined structure is characterized in that the wheel frame and the spokes are both made of a carbon fiber composite material, the two ends of the spokes are respectively connected with the two sides of the wheel frame and the hub, and the spokes are arranged symmetrically on two sides of the hub and distributed on the wheel frame evenly. The adjustable carbon fiber wheel rim combined structure is simple in structure, is convenient to use and is applicable to composite material vehicle wheels with or without an inner tube. By the adjustable carbon fiber wheel rim combined structure, the circular degree of the wheel frame can be changed through simple adjustment so that circular degree of a whole vehicle wheel can be ensured and the quality reliability of the carbon fiber composite material vehicle wheel can be improved.

Description

(1) Technical field The invention belongs to the field of wheel accessories, in particular to an adjustable carbon fiber rim composite structure. (2) Background technology The bicycle is mainly a means of transportation powered by human pedaling. It combines the principles of ergonomics and aerodynamics, and has many parts, including frame, fork, handle, rim, chain and so on. In order to reduce the weight of bicycles and save the physical strength of riders, bicycles have been gradually developed from metal materials to carbon fiber composite materials. Compared with metal materials, carbon fiber composite materials have a density of only 1.6g / m 3 , which is only 1 / 5 of steel, so it can greatly reduce the weight of bicycles; in addition, carbon fiber composite materials also have the advantages of excellent corrosion resistance, high specific strength, and high specific modulus; firstly, composite parts made of carbon fiber composite materials include front and rear fork...

AI Technical Summary

Problems solved by technology

For a bicycle, the wheel is the only part in direct contact with the ground among all its components, and it is also the part with the most frequent force changes. The quality of the wheel is of great significance to the smooth and safe driving of the bicycle; the roundness of the wheel is of great importance to The driving process has the greatest impact, and the roundness of the wheel is guaranteed by the rim. If the roundness of the rim is not good, it will cause problems such as poor fit between the tire and the rim, low conversion rate of riding energy, and unstable driving. , will affect the riding effect

For traditional bicycles, the roundness of the rim depends on the simultaneous action of dozens of steel wire spokes between the left and right sides of the wheel hub and the rim to keep it round, while for new carbon fiber bicycles, especially carbon fiber rims , due to its hardness and wear resistance compared with metal materials have a certain gap, so it is difficult to adjust the roundness with the traditional spoke adjustment method, but can only be guaranteed by the precision of the mold during the forming process
