Abstract
A driving system having a hollow shaft, a solid shaft arranged in the hollow shaft, a stator, a rotor connected to the hollow shaft, a clutch mechanism selectively engaged to one of the stator and the rotor, and a speed reduction mechanism having a planetary carrier assembly engaged to the clutch mechanism, and a planetary gear train connected between the solid shaft and the rotor, wherein where the clutch mechanism is engaged to the stator in a transmission manner, the planetary carrier assembly is connected with the stator, and the rotor drives the solid shaft and the hollow shaft to operate at a differential speed, and where the clutch mechanism is engaged to the rotor in the transmission manner, the planetary carrier assembly is connected with the rotor, and the rotor drives the solid shaft and the hollow shaft to operate at a same speed by the planetary gear train.
