Abstract

本实用新型公开了一种脚踏车省力车轮,其包括有轮胎(1)、瓦圈(2)及轴承座(3)等,其特征在于:在瓦圈(2)与轴承座(3)之间联接有若干个扇叶状辐条板(4),辐条板(4)左右对称,其左侧面与右侧面均为具有一定弧度的凹面。本实用新型在侧风向行驶时,风吹扇叶会产生车轮转动的推动力,从而可达到省力的目的。

Description

一种脚踏车省力车轮
本实用新型属于脚踏车部件,具体地系一种脚踏车的车轮。
在现有技术中,脚踏车的车轮均是由轮胎、瓦圈、辐条及轴承座等组成,辐条为直杆或平面条板状体,只起到支撑和定圆的作用。因而这种车轮没有省力装置。
本实用新型的目的在于提供一种改进的自行车车轮,其克服现有技术上述之不足,具有省力作用。
为达到上述之目的,本实用新型采取的技术方案是:本实用新型包括有轮胎、瓦圈及轴承座等,其特征在于:在瓦圈与轴承座之间联接有若干个扇叶状辐条板,辐条板左右对称,其左侧面和右侧面均为具有一定弧度的凹面。
本实用新型采取上述之结构,具有以下的有益效果:
由于本实用新型在瓦圈与轴承座之间安装了扇叶状辐条板,且辐条板左右对称,因而脚踏车在处于侧风向行驶时,风吹扇叶会产生车轮转动的推动力,从而达到省力的目的。
下面结合附图对本实用新型做进一步详细介绍:
图1为本实用新型结构简图。
由图1可以看出:本实用新型包括有轮胎1、瓦圈2、轴承座3及辐条板4,辐条板4为左右对称扇叶状,其左侧面与右侧面均为具有一定弧度的凹面。
