The novel load-bearing self-locking universal wheel comprises an outer frame, a middle plate is installed in the middle of the outer frame, and the middle plate is fixedly connected with the outer frame; the wheel set comprises a wheel shaft and wheel bodies, the wheel bodies are symmetrically installed on the wheel shaft, and the wheel bodies are fixedly connected with the wheel shaft; and the shaft gear is arranged in the middle of the wheel shaft in a sleeving mode, and the shaft gear is fixedly connected with the wheel shaft. The movable shaft is installed on the outer frame, it is guaranteed that the movable shaft can achieve meshing and separation between the clamping assembly and the shaft gear through the supporting spring, and when the universal wheels are installed at the bottom of the ladder truck and the ladder truck bears loads, the movable shaft moves downwards, and the clamping assembly and the shaft gear are clamped. When the movable shaft moves upwards, the clamping assembly on the movable shaft is meshed with the shaft gear on the axle to limit the bearing to drive the wheel body to rotate, when the movable shaft moves upwards, the clamping assembly is separated from the shaft gear, at the moment, the universal wheel can move freely, and then the automatic locking and unlocking effects are achieved.

    本发明公开了一种新型负重自锁万向轮,包括:外框架,所述外框架的中部安装有中板,所述中板与外框架固定连接;轮组,所述轮组包括轮轴和轮体,所述轮体对称安装有轮轴上,且轮体与轮轴固定连接;轴齿轮,所述轴齿轮套设在轮轴的中部,且轴齿轮与轮轴固定连接。本发明通过在外框架上安装活动轴,保证活动轴可以通过支撑弹簧来实现卡合组件与轴齿轮之间的咬合和分离,当万向轮安装在登高车底部,当登高车负重时,活动轴下移,活动轴上的卡合组件与车轴上的轴齿轮相互咬合从而限制轴承带动轮体转动,活动轴上移时,卡合组件与轴齿轮相互分离,此时万向轮可以自由活动,进而实现自动锁定和解锁的效果。
