Driving module of robot, robot chassis with driving module and cleaning robot

The invention discloses a driving module of a robot, a robot chassis with the driving module and a cleaning robot. The driving module of the robot comprises a support and at least one driving assembly, and the driving assembly comprises a motor, a speed reducer and a driving wheel. The motor is arranged on the support, the speed reducer comprises a supporting body, an input shaft and an output shaft, the supporting body is connected with the support, the output shaft and the input shaft are in differential connection with the supporting body, the input shaft is connected with a motor shaft ofthe motor, the output shaft forms a shell of the speed reducer, and the driving wheel sleeves the output shaft, is a rubber-coated wheel and is connected onto the output shaft in an integral rubber-coated manner. The installation and arrangement manner of the driving module reduces the overall size of the driving assembly, so that the size of the driving module is reduced, the driving module can move on a road surface wit
