The invention relates to the technical field of trundles, in particular to a high-load universal wheel. The high-load universal wheel comprises a wheel body, a shaft bracket and a supporting plate, under the action of the flatness of the ground and the gravity center of loaded goods, differentiated stress conditions can occur among a plurality of universal wheels, after the upper limit of the bearing capacity of the universal wheels is broken through, abrasion to a steering structure can be aggravated in the moving steering process of the universal wheels, and finally the effective service life of the high-load universal wheels is affected. Therefore, through the arranged supporting spring, the supporting column on the shaft bracket and the supporting frame make contact with the supporting plate in the overload state of the universal wheel, the universal wheel is converted into a directional wheel, the situation that the universal wheel turns in the overload state and consequently the structure of the universal wheel is abraded is avoided, and after the universal wheel recovers to the limit of the bearing stress value, the rotating action of the thrust bearing is recovered through the supporting spring, so that the using effect of the high-load universal wheel is maintained.

    本发明涉及脚轮技术领域,具体涉及一种高载重万向轮;包括轮体、轴架和支承板;由于地面的平整度和装载货物的重心作用下,在多个万向轮间会出现差异化的受力情况,且在突破了万向轮的承载力上限后,会在万向轮移动的转向过程中加剧对转向结构的磨损,最终影响到高载重万向轮的有效使用寿命;故此,本发明通过设置的支承弹簧,使万向轮在超载状态下将轴架上的支承柱和支承架与支承板相接触,将万向轮转变为定向轮,避免万向轮在超载状态下产生转向而造成其结构的磨损,并在万向轮恢复到承载应力值的限度后,通过支承弹簧恢复推力轴承的转动作用,从而维持高载重万向轮的使用效果。
