DRIVING & CHASSIS - DRIVING SYSTEM HS120V 1.1 OVERVIEW 1. DRIVING SYSTEM G5:9HM:=FGH 8F=J=B;7 756=B 9B;=B9 9@97HF=7GMGH9A =B89L As the engine’s rotating power is supplied to the HST pump through the coupling assembly of the engine flywheel, the hydraulic oil pressure built in the HST pump is delivered to the driving HST motors on the left and right sides of the vehicle. Meanwhile, the front and rear wheels are installed on the axle cases in a row and the sprocket of each axle case is connected and fixed to the driving motor with a chain to deliver rotating power from the driving motor to the wheels.
