DRIVING WHEEL

A driving wheel comprises an axle, a wheel body, and a driving assembly. The wheel body is of a hollow structure and is rotatably arranged on the axle. The driving assembly comprises a shell, a motor, and a transmission mechanism. The shell is fixedly arranged on the axle and located in the wheel body, and the motor is fixedly arranged in the shell and connected to the wheel body by the transmission mechanism. An output shaft of the motor is arranged perpendicular to the axle, which can reduce the space occupied by the motor and improve space utilization.
