The invention discloses a monorail driving unit. The monorail driving unit comprises a motor and a gear box, the gear box is of a speed reduction structure of a planetary speed reduction mechanism, the motor and the gear box share the same box body, the box body comprises a front box body and a rear box body, one part of the front box body is used for forming a motor shell, and the other part of the front box body and the rear box body jointly form a gear box shell. Preferably, the motor shell also comprises a water cooling wall and a front box cover, and water cooling channels are arranged onthe water cooling wall and the front box body; the motor comprises a stator and a rotor fixed on a rotor inner core, and two ends of the rotor inner core are rotatably supported on the front box cover and the front box body respectively; the rotor inner core is of a hollow structure, a gear shaft is arranged in the rotor inner core in a penetrating mode, and the rotor inner core and the gear shaft are connected in a spline fit mode. The gear shaft forms a sun gear of the planetary reduction mechanism. The monorail driving unit has the beneficial effects of compact layout, small structural size, light weight, sufficient cooling of the motor and the gear box, good heat dissipation effect, large output torque and long service life.
