Spoke-free bamboo ring wheel

Abstract

The invention relates to a spoke-free bamboo ring wheel, which is characterized by comprising a wheel disk, a central hub, large bamboo rings, small bamboo rings and limiting blocks, wherein a triangular block matched with outer-diameter circular arcs of the large bamboo rings is arranged on the outer circle of the central hub; the large bamboo rings are coincided with circular arcs of the triangular block of the central hub; the small bamboo rings are arranged in spaces among the large bamboo rings; and the limiting blocks are arranged on two sides of contacts between the large and small bamboo rings and the inner side of the wheel disk. The spoke-free bamboo ring wheel has the advantages of greatly shortening the assembly working hours of wheels and simplifying the assembly of the wheels. Bamboos are put into water and can float on the water; due to the use of bamboo wheels, the gravity of a bicycle can be reduced; the elasticity and the strength of the bamboo wheels are much higherthan those of a spoke; if a large batch of bamboo wheels appear in the market, metal spoke wheels can be replaced gradually; and by using rich resources of natural bamboos in China, a large quantity of metal resources can be saved.

Description

technical field [0001] The invention belongs to bicycle parts, in particular to a spokeless bamboo rim wheel for bicycles and tricycles. Background technique [0002] Bicycle wheels with metal spokes tensioning the rim are two hundred years old. The installation of the wheel of this kind of structure requires manual "taking the dragon" to adjust the roundness, which is very time-consuming. The installation workload of two wheels accounts for 60%-70% of the entire bicycle assembly. After one to two years, the spokes and nipples will be rusted, and the deformed wheel cannot be adjusted by threading, and the wheel cannot be repaired and can only be scrapped. At the same time, bicycle wheels are made of metal, which consumes a large amount of iron, aluminum, and copper, which is not environmentally friendly and consumes a large amount of energy, causing great waste to the society and the country. [0003] my country's bamboo production area is very wide, as long as there is w...
