📋 Original Product Description:

Hyundai Hl780-3aWheel Loader Workshop Repair Service Manual Download

The Torque converter is composed of 3 main components :

Pump wheel – turbine wheel – stator(Reaction member)
These 3 impeller wheels are arranged in such a ring-shape system that the fluid is streaming through
the circuit components in the indicated order.
Pressure oil is constantly streaming out of the transmission pump through the converter. In this way, the
converter can fulfill its task to multiply the torque of the engine, and at the same time, the heat created in
the converter is dissipated through the escaping oil.
The oil, escaping out of the pump wheel, enters the turbine wheel and is there inversed in the direction
of flow.
According to the rate of inversion, the turbine wheel and with it also the output shaft, receive a more or
less high reaction moment. The stator(Reaction member), following the turbine, has the task to inverse
again the oil which is escaping out of the turbine and to delivery it under the suitable discharge direction
to the pump wheel.
Due to the inversion, the stator receives a reaction moment.
The relation turbine moment/pump moment is called torque conversion. This is the higher the greater
the speed difference of pump wheel and turbine wheel will be.
Therefore, the maximum conversion is created at standing turbine wheel.
With increasing output speed, the torque conversion is decreasing. The adoption of the output speed to
a certain required output moment is infinitely variable and automatically achieved by the torque
converter.
