The invention relates to the technical field of universal wheels, and provides an anti-jamming universal wheel special for a suitcase, which comprises a universal wheel special for the suitcase, the right side of the universal wheel special for the suitcase is movably connected with a limiting block, and the top end of the universal wheel special for the suitcase is fixedly connected with a connecting frame; a main rotating wheel is movably connected to the center of the special universal wheel for the traveling case, and cleaning devices are movably connected to the upper side and the lower side of the special universal wheel for the traveling case through the main rotating wheel. When the outer part rotates at the same power, the outer part is easy to oxidize with air, and the rotating friction force of the outer part is larger, higher external power is required under the condition of keeping the same rotating speed, so that the inner heat is larger, and higher external power is required under the condition of keeping the same rotating speed, so that the inner heat is larger, and the small airbags around the rotating shaft are expanded, and the torque spring is extruded.

    本发明涉及万向轮技术领域,提供一种避免卡死的旅行箱专用万向轮,包括旅行箱专用万向轮,所述旅行箱专用万向轮的右侧活动连接有限位块,所述旅行箱专用万向轮的顶端固定连接有连接架,所述旅行箱专用万向轮的中央活动连接有主转轮,所述旅行箱专用万向轮的上下两侧均通过主转轮活动连接有清理装置,该避免卡死的旅行箱专用万向轮,通过转动轴长时间工作时,其表面没有足够的润滑油时,其外部在同功率下转动易于与空气发生氧化,且其转动的摩擦力较大,则保持同转速的情况下,需要较高的外部功率,致使内部的热量较大,则保持同转速的情况下,需要较高的外部功率,致使内部的热量较大,使转动轴四周的小型气囊膨胀,其挤压扭矩弹簧。
