The invention relates to the technical field of children products. The utility model discloses an automatic deceleration safety wheel for a buggy. The automatic deceleration safety wheel comprises a supporting shaft and a wheel body movably connected to the exterior of the supporting shaft in a sleeving mode. Wherein a reduction gearbox is fixedly installed in the wheel body, the reduction gearboxis movably connected to the outer portion of the supporting shaft in a sleeving mode, movable sleeving portions of the reduction gearbox and the supporting shaft are rotationally connected and sealedthrough a sealing bearing, and a separation cylinder is fixedly installed on the inner wall of the reduction gearbox and is in a cylinder shape. The reduction gearbox is arranged in the wheel body; the separation cylinder is arranged in the reduction gearbox; the reduction gearbox and the separation cylinder are filled with water; due to the fact that the reduction gearbox and the separation cylinder are filled with water and are communicated through damping holes, when the vehicle speed is too high, the flow quantity of water driven by auger blades is remarkably increased, the passing flow of the damping holes in unit time is limited, the water in the separation cylinder has rotating resistance relative to the auger blades, and then self-deceleration can be effectively achieved.

    本发明涉及儿童用品技术领域,且公开了一种儿童车用自动减速安全轮,包括支撑轴以及活动套接于支撑轴外部的车轮本体,所述车轮本体的内部固定安装有减速箱,所述减速箱活动套接于支撑轴的外部,且减速箱和支撑轴的活动套接部位采用密封轴承实现转动连接并密封,所述减速箱的内壁固定安装有分隔筒,所述分隔筒为圆筒型。本发明通过在车轮本体内设减速箱,在减速箱内设分隔筒,并向减速箱和分隔筒内填充满水,由于减速箱和分隔筒内均灌满水且由阻尼孔连通,当车速过快时,绞龙叶片驱动水的流动量显著提高,而阻尼孔单位时间内的通行流量有限,从而使得分隔筒内水相对绞龙叶片存在转动阻力,进而可以有效实现自减速。
