The invention provides a trundle. The trundle comprises a trundle frame, a first driving wheel, a second driving wheel, a first driving mechanism, a second driving mechanism and a vehicle body connecting seat, the vehicle body connecting seat is installed on the wheel carrier and used for connecting the wheel carrier to a vehicle body, a hinge head is arranged between the vehicle body connecting seat and the wheel carrier, the upper end of the hinge head is rotationally connected to the vehicle body connecting seat, the lower end of the hinge head is hinged to the middle of the wheel carrier, and the rotating axis of the upper end of the hinge head is perpendicular to the rotating axis of the lower end of the hinge head; the first driving wheel and the second driving wheel are rotationally connected to the two ends of the wheel frame correspondingly and located on the two radial sides of the rotating axis of the lower end of the hinge head correspondingly. The first driving mechanism and the second driving mechanism are both installed on the wheel frame and used for driving the first driving wheel and the second driving wheel to rotate correspondingly. The structure can prevent the trundle from being suspended, keep the adhesive force between the driving wheel and the ground, and ensure the driving reliability of the driving wheel.
本发明提供了一种脚轮,包括轮架、第一驱动轮、第二驱动轮、第一驱动机构、第二驱动机构和车体连接座;车体连接座安装在轮架上并用于将轮架连接在车体上,车体连接座与轮架之间设有铰链头,铰链头上端转动连接在车体连接座上,铰链头下端铰接在轮架的中部,铰链头上端的转动轴心线与铰链头下端的转动轴心线相互垂直设置;第一驱动轮和第二驱动轮分别转动连接在轮架的两端,且分别位于铰链头下端的转动轴心线的径向两侧;第一驱动机构和第二驱动机构均安装在轮架上,第一驱动机构和第二驱动机构分别用于驱动第一驱动轮和第二驱动轮的转动。该结构能避免脚轮悬空,保持驱动轮与地面的附着力,保证驱动轮的驱动可靠性。
