【技术实现步骤摘要】
无内胎钢圈
本技术属于机动车钢圈
,尤其是涉及一种无内胎钢圈。
技术介绍
轮毂又叫轮圈、钢圈、轱辘、胎铃,是轮胎内廓支撑轮胎的圆桶形的、中心装在轴上的金属部件。轮毂根据直径、宽度、成型方式、材料不同种类繁多。由于无内胎轮胎安全性、经济性、环保性等性能均较好,目前已普遍采用,取代有内胎的车轮,因此无内胎钢圈应用越来越广泛。安装在无内胎钢圈上的轮胎需要更换时,先卸下车轮,再扒下轮胎。普通的更换方式是,在扒胎时用竹板撬起一边后,将车胎两边尽量向中间压,此种换胎方式稍不注意容易将车胎两边缘弄破。
技术实现思路
本技术的目的是要解决现有技术的不足之处,而提供一种可快速拆卸无内胎轮胎,且不伤害钢圈的无内胎钢圈。本技术的目的是通过下列技术方案解决的:一种无内胎钢圈,其特征在于:包括轮辋、辐板和气门嘴;所述轮辋边缘向两侧延伸并凸起形成轮胎座,轮胎座边缘向两侧延伸凸起形成轮缘;所述轮辋内圆侧设有辐板,辐板上设有气门嘴;所述轮缘上设有轮胎更换辅助装置,包括撬板和把手;所述撬板为弧形板状结构,设置在轮缘上,且其弧度与轮缘相配合,所述撬板外侧设有一转轴,轮缘外侧设有与转轴相配合转轴支撑座,所述撬板通过转轴与转轴支撑座转动连接,撬板边缘设有一圈密封条;所述转轴一端开有一盲孔,盲孔的横截面为多边形,所述把手包括一长条形手柄,手柄一端垂直设有柄头,所述柄头的形状和盲孔形状相配合。基于上述结构,在更换无内胎轮胎时,将把手的柄头嵌入盲孔内,转动手柄即可带动转轴转动,撬板即可轻松将轮胎边缘撬起,将无内胎轮胎从无内胎钢圈上拆下,同时不对钢圈造成伤害。可选择的,本技术所述轮胎更换辅助装置的个数为1 ...
