Transmission System

With closed double-loop hydraulic transmission system and planet decelerator, tension wheel is driven by primary gear. With inversion, the magnitude of reverse traction force is led by exit pressure of pump. In tension condition, hydraulic motor rotation is driven by the tension wheel; the magnitude of tension is controlled by regulating the motor exit pressure.
