Planetary gear transmission is not only suitable for high-speed, high power and canbeused in low speed andheavy torqueofmechanical device，these effectshavea very important significance for modern mechanical transmission development. In this paper, we adopt two 2K-H planetary gear reducer.This reducer has advantages of small volume, big transmission ratio, high transmission efficiency, input shaft and the output shaft with the same shaft.When the truck doesnot need electric power walking,we can easily achieve power separation from the motor to the drive wheels by manipulating theclutch operatingmechanism.Wecan slidethetruck easily.
