Transmission System
With closed double-loop hydraulic transmission system and planet decelerator, tension wheel is driven by primary gear. hen inverted, 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. | ||
