The invention belongs to the technical field of trundles, and particularly relates to a multifunctional heavy-load dustproof damping universal wheel which comprises a mounting plate, supporting rings,supporting discs, wedge-shaped rings, a connecting ring, an annular sheet, a rivet, first steel balls, a second steel ball, a supporting plate, rollers, a first rotating shaft and brake components. According to the universal wheel, through the combination of the supporting rings, the supporting discs and the first steel balls and the combination of annular arc protrusions, annular bosses and thefirst steel balls, the universal wheel can bear axial loads and radial loads when rotating horizontally, and then the bearing capacity of the universal wheel is improved; the rollers are locked by controlling brake parts, meanwhile, the brake components drive the connecting rings to move upwards, then the wedge-shaped rings are driven to move upwards, then the two side walls of each wedge-shaped ring make contact with the inner wall of the corresponding annular protrusion and the side wall of the corresponding supporting disc correspondingly, then the supporting rings and the supporting discsdo not rotate any more, and horizontal rotation of the universal wheel is locked; and therefore, the universal wheel is prevented from rotating, and the safety of the universal wheel is improved.

    本发明属于脚轮技术领域,具体的说是一种多功能重载防尘减震万向轮,包括安装板、支撑环、支撑盘、楔形环、连接环、环形薄片、铆钉、一号钢球、二号钢球、支撑板、滚轮、一号转动轴和刹车部件;本发明中通过支撑环、支撑盘和一号钢球组合,并且环状圆弧凸起、环形凸台和一号钢球组合,进而使得万向轮水平转动即能承受轴向载荷又能承受径向载荷,进而提高了万向路的承载能力;通过控制刹车部件锁死滚轮,同时刹车部件带动连接环向上运动,进而带动楔形环向上运动,进而楔形环的两个侧壁分别与环状凸起的内壁和支撑盘的侧壁接触,进而使得支撑环和支撑盘之间不在转动,进而锁死了万向轮的水平转动,进而防止万向轮发生转动,提高了万向轮的安全性。
