The wheel braking device comprises a fixing shaft, a first sleeve and a second sleeve, the two ends of a steel ball containing frame are sleeved with the first sleeve and the second sleeve respectively, the fixing shaft is sleeved with the first sleeve, the second sleeve and the steel ball containing frame, and the first sleeve and the second sleeve rotate synchronously with the steel ball containing frame. The steel ball containing frame comprises a lantern ring, a containing ring plate, a supporting ring containing groove and a plurality of mounting cavities. The end fixing plates are arranged on the opposite side walls of the mounting cavity, it can be guaranteed that the first sleeve or the second sleeve extrudes the first steel ball movable frame and the second steel ball movable frame between the sliding rods and is not hindered by the end fixing plates, and the first steel ball movable frame and the second steel ball movable frame stretch out and draw back in the mounting cavity; it needs to be explained that the diameter of the braking steel ball is larger than the thickness of the mounting cavity, and therefore it can be guaranteed that the first sleeve or the second sleeve extrudes the braking steel ball and is not hindered by the placing annular plate.

    本发明公开了一种用于骑行单车的车轮制动装置,包括固定轴以及分别套设在钢珠容纳架两端的第一套管和第二套管,所述第一套管、第二套管和钢珠容纳架均套设在固定轴上,且第一套管和第二套管均与钢珠容纳架同步转动,所述钢珠容纳架包括套环、放置环板、支撑环放置槽和多个安装腔。本发明采用端部固定板设置在安装腔相对侧壁可以保证第一套管或第二套管通过挤压滑动杆之间的第一钢珠活动架与第二钢珠活动架并不会受到端部固定板的阻碍,而第一钢珠活动架与第二钢珠活动架在安装腔内伸缩,需要说明的是,制动钢珠的直径大于安装腔的厚度这样能够保证第一套管或第二套管挤压制动钢珠不会受到放置环板的阻碍。
