The invention provides a novel trundle device which enables the resistance of a trundle to be reduced when the trundle rotates in situ so as to slow down the abrasion speed of a trundle body. The trundle device comprises a caster mounting seat and wheels, the trundle mounting seat is integrated with a rotating shaft part and a wheel assembling frame, the rotating shaft part drives the whole wheel assembling frame to rotate, and the wheel assembling frame is used for mounting the wheels; each wheel comprises a supporting outer ring and a center assembling part, the bottom of each supporting outer ring is supported on the ground, and each center assembling part is fixedly connected to the corresponding wheel assembling frame; a rotation center shaft of the rotating shaft part is vertically arranged, and the offset distance of the center point of the wheel in the thickness direction relative to a wheel parallel arrangement surface where the rotation center shaft is located is p, so a deflection angle theta exists between a connecting line between the rotation center shaft and the center point of the wheel in the thickness direction and the wheel parallel arrangement surface; and the wear rate of the wheel is reduced by introducing the deflection angle theta so that the service life of the wheel is prolonged.
本发明提供了一种新型脚轮装置,其使得脚轮在原地回转时的阻力减小,从而减缓轮体的磨损速度。其包括脚轮安装座、轮子;所述脚轮安装座集成有转轴部分、轮子组装架,所述转轴部分驱动轮子组装架的整体旋转,所述轮子组装架用于安装所述轮子;所述轮子包括支承外圈、中心组装部分,所述支承外圈的底部支承于地面,所述中心组装部分固接于所述轮子组装架;所述转轴部分的回转中心轴竖直向布置,所述轮子的厚度方向中心点相对于回转中心轴所在的轮子平行布置面的偏置距离为p,使得回转中心轴和轮子的厚度方向中心点之间的连线和轮子平行布置面之间存在偏角θ,通过引入此偏角θ减缓轮子的磨损速率,从而增加轮子的使用寿命。
