ABSTRACT:
A triple-axle-drive multistage transmission for heavy machinery includes an input part and a speed changing part. The input part includes a clutch part including a forward clutch part and a reverse clutch part to control transmission of the power received from a bevel gear unit, an input drive shaft coupled to the forward clutch part to mediate forward power transmission, a forward drive gear provided on a first end of the input drive shaft, and a reverse drive gear coupled to the reverse clutch part. The speed changing part includes a speed change drive shaft to mediate a change of speed of the power input from the input part, a planetary gear unit coupled to a first end of the speed changed drive shaft, and a reverse driven gear provided on a second end of the speed change drive shaft and engaging with the reverse drive gear.
