The invention discloses a universal wheel and a transportation device comprising the same. The universal wheel comprises a wheel body, a wheel body support connected with a wheel body shaft, a middlesupport installed on the wheel body support and a wheel seat installed on the middle support. The wheel body support and the middle support form a first revolute pair, and the wheel seat and the middle support form a second revolute pair. A rotating shaft of the first revolute pair penetrates through the mounting center of the middle support and deviates from the radial center of the wheel body, and a rotating shaft of the second revolute pair deviates from the mounting center of the middle support and deviates from the radial center of the wheel body. The universal wheel is provided with thetwo revolute pairs used for steering, so that when the universal wheel is steered, the two revolute pairs act together, the sliding distance of the wheel body is reduced, and then the steering resistance of the universal wheel is reduced.

    本申请公开了一种万向轮以及包括其的运输装置。该万向轮包括轮体,与轮体轴连接的轮体支架,安装在轮体支架上的中间支架,以及安装在中间支架上的轮座,轮体支架与中间支架形成第一转动副,轮座与中间支架形成第二转动副,第一转动副的转轴穿过中间支架的安装中心并偏离轮体的径向中心,第二转动副的转轴偏离中间支架的安装中心并偏离轮体的径向中心。根据本申请的万向轮具有两个用于转向的转动副,在万向轮转向时,两个转动副共同作用,减小了轮体的滑动距离,进而减小了万向轮的转向阻力。
