Abstract

本实用新型公开了一种能增大刹车摩擦系数的车圈,属于自行车部件,该能增大刹车摩擦系数的车圈,包括车圈侧壁、内胎、外胎、辐条,其特征是:所述车圈两侧壁表面有条形斑纹或点状的凹凸体。本实用新型的有益效果是因为车圈两侧壁的表面粗糙不光滑,这样当捏轧刹车时,能极大地增加轧皮和车圈之间接触面的摩擦系数,增大摩擦力,提高刹车性能,用较小的力就能灵敏刹车。

Description

能增大刹车摩擦系数的车圈
技术领域
本实用新型属于自行车部件。
背景技术
一般自行车金属车圈的两侧壁都是光滑的,在捏轧刹车时,靠外力挤压轧皮使其增加与车圈侧壁间的摩擦力,达到刹车效果,这样比较费力,刹车不灵敏。
实用新型内容
为了克服现有自行车刹车比较费力且不灵敏的不足,本实用新型的目的是提供一种能增大刹车摩擦系数的车圈。
本实用新型解决其技术问题所采用的技术方案是:一种能增大刹车摩擦系数的车圈,包括车圈侧壁、内胎、外胎、辐条,其特征是:所述车圈两侧壁表面有条形斑纹,或点状的凹凸体。
本实用新型的有益效果是因为车圈两侧壁的表面粗糙不光滑,这样当捏轧刹车时,能极大地增加轧皮和车圈之间接触面的摩擦系数,增大摩擦力,提高刹车性能,用较小的力就能灵敏刹车。
附图说明
附图1为本实用新型的结构示意图,
图中,1.车圈侧壁,2.内胎,3.外胎,4.辐条,5侧壁表面。
具体实施方式
本实用新型的具体实施方式是,如图所示:
实施例1,一种能增大刹车摩擦系数的车圈,包括车圈侧壁1、内胎2、外胎3、辐条4,所述车圈两侧壁表面5有条形斑纹或点状的凹凸体。
