The universal wheel with the double-brake structure comprises a support, two rotating wheels, a universal structure and the double-brake structure, the universal structure comprises a main shaft and a main bearing, the double-brake structure comprises a brake locking handle, a brake unlocking handle, a shifting fork, a shaft locking unit and a wheel locking unit, and the shaft locking unit is connected with the main shaft and the shifting fork. The wheel locking unit is arranged at the other end of the shifting fork and matched with the brake wheel. The middle of the shifting fork is hinged to the support through a pin. According to the universal wheel with the double-brake structure, locking and unlocking of the main shaft are achieved through meshing and separation of the upper fluted disc and the lower fluted disc, the reliability is good, locking and unlocking of the rotating wheel are achieved through contact and separation of the brake pad and the brake wheel, and then the rotating wheel is locked and unlocked through cooperation of the locking brake handle, the unlocking brake handle and the shifting fork. Meanwhile, the meshing state of the upper fluted disc and the lower fluted disc and the contact state of the brake pad and the brake wheel are controlled, so that the rotating wheel and the main shaft are locked at the same time, all-directional braking is achieved, and operation is convenient and fast.
本发明公开一种具有双刹结构的万向轮,包括支架、两个转动轮、万向结构和双刹结构,万向结构包括主轴和主轴承,双刹结构包括锁刹把、开刹把、拨叉、轴锁止单元和轮锁止单元,轴锁止单元与主轴和拨叉连接,轮锁止单元设置于拨叉另一端且与刹轮配合,拨叉中部通过销钉铰接于支架;本发明的具有双刹结构的万向轮,通过上齿盘和下齿盘的啮合和分离,实现对主轴的锁死和解锁,可靠性好,通过刹片与刹轮的接触和脱离,实现对转动轮的锁死和解锁,进而通过锁刹把、开刹把和拨叉的配合,同时控制上齿盘与下齿盘的啮合状态和刹片与刹轮的接触状态,以同时对转动轮和主轴实施锁止,实现全方位刹车制动,操作便捷。
