The invention discloses a steel bowl assembly of an electric bicycle with a simple structure. The steel bowl assembly is composed of a steel bowl, a steel ball and ball frame, a retaining ring and convex points, and is characterized in that the steel ball and ball frame are placed in the steel bowl, the retaining ring is placed on the steel ball and ball frame, the convex points are arranged on the retaining ring and distributed on the inner side surface of the steel bowl, and the convex points are symmetrically or equidistantly distributed on the inner circumferential edge of the steel bowl;the number of convex points can be even or odd except 1; and the convex points are spot welded with a spot welder after the retaining ring is placed. The steel bowl assembly has the beneficial effectsthat a clamping ring is removed, the convex points in the steel bowl are increased, the convex points are used for playing the role of the clamping ring, the retaining ring is clamped to be unable toslide outwards, thus accessories of one clamping ring are saved, and the cost of a product is lowered; and meanwhile the procedure of placing the clamping ring is reduced, and the production efficiency is improved.
本发明公开了一种结构简单的电动车自行车钢碗组件,由钢碗、钢珠及球架、挡圈和凸点组成,其特征在于:所述的钢碗内放置钢珠及球架,在钢珠及球架上放置挡圈,挡圈上有凸点,所述的凸点分布在钢碗内侧面上,所述的凸点在钢碗内圆周边上是对称分布,或等距离分布的;凸点个数可以是除1以外的偶数与奇数;所述的凸点是在放置挡圈后,用点焊机点焊上去的。有益效果是:通过去除卡圈、增加在钢碗内的凸点、用凸点起到卡圈的作用,卡住挡圈不能向外滑动,这样节省了一个卡圈的配件,降低了产品的成本;同时少了一道放置卡圈的工序,提高了生产效率。
