5-10t Internal Combustion Counterbalance Forklift Truck Operation & Maintenance Manual
pulley will rotate freely, when the abovementioned reactively moment effects reversely, and
under such working condition, the input torque is equal to the output torque, this to ensure a
high-efficiency work.
The torque converter changes the transmission of moment of force depending on mechanical
method (clutch), and it plays the two functions of coupler and torque converter, hence called
two phases. It is characterized by stable operation and improved efficiency.
One-way clutch, turbine, pump impeller, and guide pulley are installed inside the torque
converter, and the internal part of the torque converter is filled up with torque converter oil,
with warning point of oil temperature as 105ā.
One gear in the end part of pump impeller is mutually engaged with the driving gear of oil
feed pump, to actuate the oil feed pump.
Turbine is coupled with the input shaft (transmission) using spline, and it plays the function
for power to be transmitted to hydraulic clutch.
Refer to Fig 3-2 for structure of torque converter.
